Subject: [PATCH 0001/1722] openvswitch: Use eth_mac_addr() instead of
 duplicating it

bonus: if we ever are to use IFF_LIVE_ADDR_CHANGE for
anything further than to check availability in eth_mac_addr(),
Open vSwitch will be ready for that.

Subject: [PATCH 0004/1722] openvswitch: Change ENOENT return value to ENODEV
 in lookup_vport().

This reduces the number of valid "no such device" error values that
need special attention by the caller.

Userspace code will need to keep on checking for both ENODEV and
ENOENT as long as older kernel modules are around.

Subject: [PATCH 0005/1722] openvswitch: Allow OVS_USERSPACE_ATTR_USERDATA to
 be variable length.

Until now, the optional OVS_USERSPACE_ATTR_USERDATA attribute had to be
exactly 64 bits long, if it was present.  However, 64 bits is not enough
space to associate as much information with a flow as would be convenient
for some userspace features now under development.  This commit generalizes
the attribute, allowing it to be any length.

This generalization is backward-compatible: if userspace only uses 64-bit
attributes, then it will not see any change in behavior.

BQL (Byte Queue Limits) proper operation needs TX completion

bnx2x uses a non standard NAPI poll weight, and thats not fair to other
napi poll handlers, and even not reasonable.

Use the default value instead.

Subject: [PATCH 0017/1722] xfrm: allow to avoid copying DSCP during
 encapsulation

By default, DSCP is copying during encapsulation.
Copying the DSCP in IPsec tunneling may be a bit dangerous because packets with
different DSCP may get reordered relative to each other in the network and then
dropped by the remote IPsec GW if the reordering becomes too big compared to the
replay window.

It is possible to avoid this copy with netfilter rules, but it's very convenient
to be able to configure it for each SA directly.

This patch adds a toogle for this purpose. By default, it's not set to maintain
backward compatibility.

Field flags in struct xfrm_usersa_info is full, hence I add a new attribute.

magic -1 variable that isn't in the enum, but an explicit change
flag; reject invalid plink states or actions and move the needed
constants for plink actions to the right header file. Also
reject plink_state changes for non-mesh interfaces.

All the pointers point right into the skb data and
not to anything that would be useful to change, so
make them const.

drivers are called, and as a result it is difficult to see
what should be allowed and what not.

In order to comprehensively check the API parameters parse
everything first, and then have the driver call a function
(cfg80211_check_station_change()) with the additionally
information about the kind of station that is being changed;
this allows the function to make better decisions than the
old code could.

While at it, also add a few checks, particularly in mesh
and clarify the TDLS station lifetime in documentation.

To be able to reduce a few checks, ignore any flag set bits
when the mask isn't set, they shouldn't be applied then.

Subject: [PATCH 0024/1722] net: rfkill: Fix sparse warning in
 rfkill-regulator.c

'rfkill_regulator_ops' is used only in this file. Hence make it static.
Silences the following warning:
net/rfkill/rfkill-regulator.c:54:19: warning:
symbol 'rfkill_regulator_ops' was not declared. Should it be static?

Subject: [PATCH 0025/1722] mac80211: clarify alignment comment

The comment says something about __skb_push(), but that
isn't even called in the code any more. Looking at the
git history, that comment never even made sense when it
was still called, so just replace that part to note it
still works even when align isn't 0 or 2.

Subject: [PATCH 0026/1722] nl80211: allow splitting wiphy information in dumps

The per-wiphy information is getting large, to the point
where with more than the typical number of channels it's
too large and overflows, and userspace can't get any of
the information at all.

To address this (in a way that doesn't require making all
messages bigger) allow userspace to specify that it can
deal with wiphy information split across multiple parts
of the dump, and if it can split up the data. This also
splits up each channel separately so an arbitrary number
of channels can be supported.

Additionally, since GET_WIPHY has the same problem, add
support for filtering the wiphy dump and get information
for a single wiphy only, this allows userspace apps to
use dump in this case to retrieve all data from a single
device.

As userspace needs to know if all this this is supported,
add a global nl80211 feature set and include a bit for
this behaviour in it.

From cdc89b97bf23ae3a7869804b6dc13be011ec8f4c Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Mon, 18 Feb 2013 23:54:36 +0100
Subject: [PATCH 0027/1722] nl80211: conditionally add back radar information

If userspace is updated to deal with large split wiphy
information dumps, add back the radar information that
could otherwise push the data over the limit of the
netlink dump messages.

Subject: [PATCH 0028/1722] nl80211: conditionally add back TCP WoWLAN
 information

Add back the previously removed TCP WoWLAN information,
but only if userspace is prepared to deal with large
wiphy capability data dumps.

Subject: [PATCH 0029/1722] wireless: move sequence number arithmetic to
 ieee80211.h

Move the sequence number arithmetic code from mac80211 to
ieee80211.h so others can use it. Also rename the functions
from _seq to _sn, they operate on the sequence number, not
the sequence_control field.

Also move macros to convert the sequence control to/from
the sequence number value from various drivers.

Subject: [PATCH 0030/1722] ieee80211: mark 802.11 related structs as being
 2-byte aligned

Regardless of what header features they use, or if they align the IP
header or not, 802.11 packets from all drivers guarantee a 2-byte
alignment (and there's a debug WARN_ON in case they don't).

Annotate packet structs with __aligned(2) to allow the compiler to use
16-bit load/store operations on platforms with extremely inefficient
unaligned access (e.g. MIPS).

This reduces code size and improves performance on affected platforms
and causes no binary code change on others.

Subject: [PATCH 0032/1722] cfg80211: move exported event functions into
 nl80211

This is the sort of thing gcc's LTO could do, but since
we don't have that yet we can also do it manually. The
advantage is reduced code, both source and binary, e.g.
on x86-64

   text	   data	    bss	    dec	    hex	filename
 442825	  56230	    776	 499831	  7a077	cfg80211.ko (before)
 441585	  56230	    776	 498591	  79b9f	cfg80211.ko (after)

a reduction of ~1k.

But in order to not complicate the code move only those
functions that are simple wrappers, not those that have
functionality of their own.

Subject: [PATCH 0033/1722] wireless: remove unused VHT MCS defines

There's an enum with the same values (but slightly
different names except for NOT_SUPPORTED) that is
actually used, so remove the defines.

Subject: [PATCH 0034/1722] cfg80211: add ability to override VHT capabilities

For testing it's sometimes useful to be able to
override certain VHT capability advertisement,
add the ability to do that in cfg80211.

Subject: [PATCH 0036/1722] cfg80211: refactor association parameters

cfg80211_mlme_assoc() has grown far too many arguments,
make the caller build almost all of the driver struct
and pass that to the function instead.

From d339d5ca8eee34f3c70386cf2545edc53e546a13 Mon Sep 17 00:00:00 2001

Subject: [PATCH 0037/1722] mac80211: Allow drivers to differentiate between
 ROC types

Some devices can handle remain on channel requests differently
based on the request type/priority. Add support to
differentiate between different ROC types, i.e., indicate that
the ROC is required for sending managment frames.

Subject: [PATCH 0038/1722] cfg80211: prohibit zero keepalive interval

It's not useful to specify a 0 keepalive interval, this
would send too much data. Prohibit this to also avoid
device issues.

Subject: [PATCH 0039/1722] cfg80211: Extend support for IEEE 802.11r Fast BSS
 Transition

Add NL80211_CMD_UPDATE_FT_IES to support update of FT IEs to the WLAN
driver and NL80211_CMD_FT_EVENT to send FT events from the WLAN driver.
This will carry the target AP's MAC address along with the relevant
Information Elements. This event is used to report received FT IEs
(MDIE, FTIE, RSN IE, TIE, RICIE). These changes allow FT to be supported
with drivers that use an internal SME instead of user space option (like
FT implementation in wpa_supplicant with mac80211-based drivers).

Subject: [PATCH 0040/1722] mac80211/minstrel_ht: improve accuracy of
 throughput metric at high data rates

At high data rates the average frame transmission durations are small
enough for rounding errors to matter, sometimes causing minstrel to use
slightly lower transmit rates than necessary.
To fix this, change the unit of the duration value to nanoseconds
instead of microseconds, and reorder the multiplications/divisions when
calculating the throughput metric so that they don't overflow or
truncate prematurely.
At 2-stream HT40 this makes TCP throughput a bit more stable.

 selection

max_prob_rate should be selected to be very reliable, however limiting
it to single-stream on 3-stream devices is a bit much.
Allow max_prob_rate to use one stream less than the max_tp_rate.

Try to sample all available rates, as sample attempts do not cost much
airtime and are appropriately spaced based on the average A-MPDU length.
This helps with faster recovery on rate fluctuations.

Subject: [PATCH 0043/1722] mac80211/minstrel_ht: increase sampling frequency
 of some slower rates

If a rate is below the max_tp_rate, sample it frequently if:
- it is above max_tp_rate2, or
- it is above max_prob_rate and is a candidate for max_prob_rate
  (has fewer streams than max_tp_rate).
This helps the retry chain recover more quickly from bad statistics
caused by collisions or interference, and slightly reduces throughput
fluctuations with higher rates.

To fix the problem disconnect from any associated network before
suspend. User space is responsible to establish connection again
after resume. This basically need to be done by user space anyway,
because associated stations can go away during suspend (for example
NetworkManager disconnects on suspend and connect on resume by default).

Patch also handle situation when driver refuse to suspend with wowlan
configured and try to suspend again without it.

Subject: [PATCH 0047/1722] mac80211: cleanup generic suspend/resume procedures

Since now we disconnect before suspend, various code which save
connection state can now be removed from suspend and resume
procedure. Cleanup on resume side is smaller as ieee80211_reconfig()
is also used for H/W restart.

Subject: [PATCH 0052/1722] mac80211: remove IEEE80211_KEY_FLAG_WMM_STA

There's no driver using this flag, so it seems
that all drivers support HW crypto with WMM or
don't support it at all. Remove the flag and
code setting it.

Subject: [PATCH 0053/1722] mac80211: defer tailroom counter manipulation when
 roaming

During roaming, the crypto_tx_tailroom_needed_cnt counter
will often take values 2,1,0,1,2 because first keys are
removed and then new keys are added. This is inefficient
because during the 0->1 transition, synchronize_net must
be called to avoid packet races, although typically no
packets would be flowing during that time.

To avoid that, defer the decrement (2->1, 1->0) when keys
are removed (by half a second). This means the counter
will really have the values 2,2,2,3,4 ... 2, thus never
reaching 0 and having to do the 0->1 transition.

Note that this patch entirely disregards the drivers for
which this optimisation was done to start with, for them
the key removal itself will be expensive because it has
to synchronize_net() after the counter is incremented to
remove the key from HW crypto. For them the sequence will
look like this: 0,1,0,1,0,1,0,1,0 (*) which is clearly a
lot more inefficient. This could be addressed separately,
during key removal the 0->1->0 sequence isn't necessary.

(*) it starts at 0 because HW crypto is on, then goes to
    1 when HW crypto is disabled for a key, then back to
    0 because the key is deleted; this happens for both
    keys in the example. When new keys are added, it goes
    to 1 first because they're added in software; when a
    key is moved to hardware it goes back to 0

Subject: [PATCH 0054/1722] mac80211: flush keys when stopping AP

Since hostapd will remove keys this isn't usually
an issue, but we shouldn't leak keys to the next
BSS started on the same interface. For VLANs this
also fixes a bug, keys that aren't removed would
otherwise be leaked.

Subject: [PATCH 0057/1722] mac80211: fix HT capability overrides for AP
 station

HT capabilites are asymmetric -- e.g. beamforming is both an
RX and TX capability. If, for example, we support RX but not
TX, the RX capability of the AP station is masked out (if it
supports it). This works correctly if it's really the driver
capability.

If, on the other hand, the reason for not supporting TX BF
is that it was removed by HT capability overrides then the
wrong thing happens: the AP's TX capability will be removed
rather than its RX capability, because the override function
works on own capabilities, not remote ones, and doesn't take
the asymmetry into account.

To fix this make a copy of our own capabilities, apply the
overrides to them (where needed) and then use that to set up
the peer's capabilities.

Subject: [PATCH 0058/1722] mac80211: restrict peer's VHT capabilities to own

Implement restricting peer VHT capabilities to the device's own
capabilities. This is useful when a single driver supports more
than one device and the devices have different capabilities
(often they will differ in the number of spatial streams), but
in particular is also necessary for VHT capability overrides to
work correctly -- otherwise it'd be possible to e.g. advertise,
due to overrides, that TX-STBC is not supported, but then still
use it to TX to the AP because it supports RX-STBC.

Subject: [PATCH 0061/1722] regulatory: allow VHT channels in world roaming

For VHT, the wider bandwidths (up to 160 MHz) need
to be allowed. Since world roaming only covers the
case of connecting to an AP, it can be opened up
there, we will rely on the AP to know the local
regulations.

Subject: [PATCH 0062/1722] mac80211/minstrel_ht: disable multiple consecutive
 sample attempts

The last minstrel_ht changes increased the sampling frequency for
potentially useful rates to decrease the response time to rate
fluctuations. This caused an increase in sampling frequency that can
slightly reduce throughput, so this patch limits the sampling attempts
to one per rate instead of two.

 minstrel

Both rate control algorithms (minstrel and minstrel_ht) calculate
averages based on EWMA. Shift function minstrel_ewma() into
rc80211_minstrel.h and make use of it in both minstrel version.
Also shift the default EWMA level (75%) definition to the header file
and clean up variable usage.

Subject: [PATCH 0066/1722] mac80211: extend minstrel's rate sampling to avoid
 unsampled rates

Minstrel's decision which rate should be directly sampled within the
1st mrr stage is limited to such rates faster than the current max
throughput rate. All rates below the current max. throughput rate
are indirectly sampled via the 2nd mrr stage.
This approach leads to deprecated per rate statistics and therfore
a deprecated mrr chain setup.

This patch uses the sampling approach from minstrel_ht. A counter is
added to sum all indirect sample attempts per rate. After 20 indirect
sampling attempts the rate is directly sampled within the 1st mrr stage.
Therefore more up-to-date statistics for all rates are maintained and
used to setup the mrr chain.

Subject: [PATCH 0067/1722] mac80211: add lowest rate into minstrel's random
 rate sampling table

While minstrel bootstraps and fills the success probabilities of each
rate the lowest rate has typically a very high success probability
(often 100% in our tests).
Its statistics are never updated but considered to setup the mrr chain.
In our tests we see that especially the 3rd mrr stage (which is that
rate providing highest success probability) is filled with the lowest rate
because its initial high sucess probability is never updated. By design
the 4th mrr stage is filled with the lowest rate so often 3rd and 4th
mrr stage are equal.

This patch follows minstrels general approach of assuming as little
as possible about rate dependencies. Consequently we include the
lowest rate into the random sampling table to get balanced up-to-date
statistics of all rates and therefore balanced decisions.

Subject: [PATCH 0069/1722] mac80211: improve minstrels rate sorting by means
 of throughput & probability

This patch improves the way minstrel sorts rates according to throughput
and success probability. 3 FOR-loops across the entire rate set in function
minstrel_update_stats() which where used to determine the fastest, second
fastest and most robust rate are reduced to 1 FOR-loop.

The sorted list of rates according throughput is extended to the best four
rates as we need them in upcoming joint rate and power control. The sorting
is done via the new function minstrel_sort_best_tp_rates().

The most robust rate selection is aligned with minstrel_ht's approach.
Once any success probability is above 95% the one with the highest
throughput is chosen as most robust rate. If success probabilities of all
rates are below 95%, the rate with the highest succ. prob. is elected as
most robust one

Subject: [PATCH 0071/1722] cfg80211: rename mesh station types

The mesh station types used to refer to whether the
station was secure or nonsecure. Really the salient
information is whether it is managed by the kernel or
userspace

Subject: [PATCH 0075/1722] mac80211: init mesh timer for user authed STAs

There is a corner case which wasn't being covered:
userspace may authenticate and allocate stations,
but still leave the peering up to the kernel.

Initialize the peering timer if the MPM is not in
userspace, in a path which is taken by both the kernel and
userspace when allocating stations.

Subject: [PATCH 0076/1722] iwlwifi: a few fixes in license

7000.c was released as GPL only by mistake: it should be
dual licensed - GPL / BSD.
The file that contains the license in the kernel is COPYING
and not LICENSE.GPL.

Subject: [PATCH 0078/1722] iwlwifi: mvm: free AGG queue when we STA is removed

When we stop an AGG session, we need to look at the sequence
numbers in in the private area of the ieee80211_sta struct.
This allows us to know is the queue is empty. To get access
to this private area, we use fw_id_to_mac_id that maps
sta_id (index of the STA in fw table) to ieee80211_sta.

When the STA exists in fw, but not in mac80211, we set
an ERR ptr in fw_id_to_mac_id.

But if we first set an ERR ptr to fw_id_to_mac_id, and only
then flush the queues, then we won't be able to access the
sequence numbers in ieee80211_sta from the reclaim flow.
This means that we will never be able to release an AGG
queue when a station is deleted.

So first, flush the queue. That will let the reclaim flow
call iwl_mvm_check_ratid_empty which will disable the AGG
queue as needed, and only then, remove the mapping in
fw_id_to_mac_id.

Subject: [PATCH 0082/1722] iwlwifi: disable greenfield transmissions as a
 workaround

There's a bug that causes the rate scaling to get stuck
when it has to use single-stream rates with a peer that
can do GF and SGI; the two are incompatible so we can't
use them together, but that causes the algorithm to not
work at all, it always rejects updates.

Disable greenfield for now to prevent that problem. The
MVM driver currently only works on devices that don't
support greenfield anyway, but better be safe and not
allow us to forget about this.

Subject: [PATCH 0084/1722] iwlwifi: mvm: support IEEE80211_AMPDU_TX_STOP_FLUSH

mac80211 tells us when we need to dump the frames from the
AGG queue instead of releasing them as single MPDUs.
Being able to differentiate between the different cases
(IEEE80211_AMPDU_TX_STOP_*) allows us to handle races better.

When the station is removed, mac80211 asks to flush and
removes the station right away.
This allows to avoid a case where we still have frames in
AGG queues, but the station has been remove already.

Note that we can have frames on the shared queues, but this
is not a problem: the station in the fw will be kept until
all the frames on the shared queues have been drained.
AGG queues are a special case since they are dynamically
allocated.

All hardware after 4965 supports this. It's likely that
it wasn't set because for 4965 it was irrelevant (HT is
only supported on 5 GHz there) and then never updated.

Instead of using (char *)__get_dynamic_array use
__get_str. The latter is actually a macro that
expands to the former in the code, but trace-cmd
in userspace can parse __get_str only.

Subject: [PATCH 0088/1722] iwlwifi: mvm: implement remote wake

With remote wake, the firmware creates a TCP connection
and sends some configurable data on it, until a special
TCP data packet from the server is received that triggers
a wakeup. The configuration is a bit tricky because it is
based on packet pattern matching but this is hidden in
the driver and the exposed API in cfg80211 is just based
on the required TCP connection parameters.

Subject: [PATCH 0089/1722] iwlwifi: mvm: set up initial SMPS/NSS station info

When a station is added, we need to tell the firmware what
the SMPS settings and number of streams are. After having
the initial data, the firmware will track future changes
by itself.

Update the NVM parsing functions to add VHT capabilities;
they are only added for 5 GHz, of course. This assumes
that all devices with NVM reading (rather than EEPROM)
that support 5 GHz have VHT, which is true right now.

Subject: [PATCH 0092/1722] iwlwifi: make device configuration bus agnostic

Newer devices can work on different buses. This means that
their configuration can be shared between different buses.
Hence the configuration structures should exported to all
the buses and not only to PCIE. Change this.

Note that this requires all the fields to be the same
amongst the buses. If differences will appear, we can always
define a part that is bus dependent. Today, this is not
needed.

Subject: [PATCH 0093/1722] iwlwifi: mvm: don't read system time when modifying
 AP/GO MAC

When modifying a MAC, we update its beacon system time which
is taken as a base to calculate TBTT. The firmware doesn't use
the new timestamp because the time is never used after the MAC
and broadcast station were added, but it is safer to not rely
on this and avoids the overhead of reading the register every
time the MAC is updated.

Subject: [PATCH 0095/1722] iwlwifi: allow selecting only MVM driver

Now that we have two drivers (DVM and MVM) stop selecting
the DVM one (but make it default) and allow enabling only
the MVM driver if so desired. Add a warning for the case
of having neither DVM nor MVM enabled -- that's useless.

From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
Date: Thu, 17 Jan 2013 09:42:25 +0200
Subject: [PATCH 0099/1722] iwlwifi: mvm: begin basic BT-Coex implementation

Send the PRIO table before the calibrations. This table
tells the fw what priority to give to what (WiFi / BT)
according to events.

Send a hardcoded BT_COEX command to the fw to enable basic
BT coexistence.

Subject: [PATCH 0100/1722] iwlwifi: mvm: handle BT-coex notification

The BT-Coex notification is sent by the fw when there are
updates wrt. BT activity. Driver action might be taken
based on the info in this notification.

For now, update the Ack/Cts_kill_msk if HID / SCO / A2DP
profiles are active.

Subject: [PATCH 0101/1722] iwlwifi: mvm: update SMPS when BT gets active

When BT traffic load gets higher, we want to avoid using the
shared antenna. In order to do so, we need to tell the AP
that we don't support MIMO any more, or at least not all
the time: in short, use the SMPS to achieve this.

Subject: [PATCH 0103/1722] iwlwifi: mvm: update firmware API - MAC ID in RX

The firmware tells the driver to what MACs the received frame
belongs (based on the time slot in which it was received).

Note that there can be several MACs if they share the same
binding.

Subject: [PATCH 0104/1722] iwlwifi: move firmware restart debugfs hook to
 op_mode

This allows to test fw restart flow. The hook in transport
layer doesn't really make the fw assert. Moving this hook
to the op_mode allows to use the fw API to actually send a
host command that will make the fw assert.

Change the restart_fw module parameter to be a boolean on
the way.

Fix a bug in writing to indirect (periphery) registers; although
writes seem successful the data is not written to the desired
address). Also fix address mask for HBUS_TARG_PRPH_RADDR and
HBUS_TARG_PRPH_WADDR registers.

Subject: [PATCH 0108/1722] team: introduce random mode

As suggested by Eric Dumazet, allow user to select mode which chooses
TX port randomly. Functionality should be more of less similar to
round-robin mode with even lower overhead.

Update r6040_phy_{read,write} to report the busy waiting result
accordingly.

HTB uses an internal pfifo queue, which limit is not reported
to userland tools (tc), and value inherited from device tx_queue_len
at setup time.

Introduce TCA_HTB_DIRECT_QLEN attribute to allow finer control.

Remove two obsolete pr_err() calls as well.

Subject: [PATCH 0112/1722] ssb: fix unaligned access to mac address

The mac address should be aligned to u16 to prevent an unaligned access
in drivers/ssb/pci.c where it is casted to __be16.

 register access failure once

BugLink: http://bugs.launchpad.net/bugs/1128840

It appears that when this register read fails it never recovers, so
I think there is no need to repeat the same error message ad infinitum.

Subject: [PATCH 0118/1722] carl9170: fix frame drop and WARN due to
 minstrel_ht change

With "mac80211/minstrel_ht: add support for using CCK rates"
minstrel_ht selects legacy CCK rates as viable rates for
outgoing frames which might be sent as part of an A-MPDU
[IEEE80211_TX_CTL_AMPDU is set].

This behavior triggered the following WARN_ON in the driver:
> WARNING: at carl9170/tx.c:995 carl9170_op_tx+0x1dd/0x6fd
The driver assumed that the rate control algorithm made a
mistake and dropped the frame.

This patch removes the noisy warning altogether and allows
said A-MPDU frames with CCK sample and/or fallback rates to
be transmitted seamlessly.

Stop returning negative values from ath5k_eeprom_mode_from_channel.
Yell loudly about that case in that function instead and return the
default/zero/mode A. This cleans up the callers, but needs to pass ah
down to ath5k_eeprom_mode_from_channel for ATH5K_WARN. For that
purpose we also need the declaration to be moved to ath5k.h.

Subject: [PATCH 0125/1722] ray_cs: read past the end of the array

"translate" should either be set or disabled.  We also use it an
offset into the framing[] array when we're generating the proc
file.  Framing looks like this:

static const char *framing[] = { "Encapsulation", "Translation" }

So when we're setting translate we need to restrict the values to
either 1 or 0 or it can an out of bounds read.

Subject: [PATCH 0126/1722] ath9k: simplify ATH_EP_RND

Remove the embedded branch to make the ATH_EP_RND macro a little
clearer.  The new version also generates better code, saving 24
bytes of text:

   text	   data	    bss	    dec	    hex	filename
  87858	   1641	     24	  89523	  15db3	ath9k_orig.ko
  87834	   1641	     24	  89499	  15d9b	ath9k_new.ko

Although neither version handles negative values particularly well,
the lone caller clamps all negative values to zero anyway.  I have
verified that the results are the same for the range of possible
positive rssi values.

Subject: [PATCH 0133/1722] brcmfmac: make debug module parameter more clear

The module parameter definition for brcmf_msg_level has been
reworked to a named module parameter with description so
modinfo is a bit more informative:

parm:           debug:level of debug output (int)

information macros are used in multiple source files:

Subject: [PATCH 0138/1722] brcmfmac: add support for TLV based firmware
 signalling

The firmware and host can exchange signals which are carried within
the data packets. These are TLV based signals that are inserted
before the actual data, ie. ethernet frame.

This commit adds the new source module for this feature and enables
RSSI signals from firmware.

Subject: [PATCH 0139/1722] brcmfmac: release transmit packet in
 brcmf_txcomplete()

In the bus-specific driver code each call to brcmf_txcomplete() is
following by a free of that packet. This patch moves that free to
the brcmf_txcomplete() function.

Subject: [PATCH 0140/1722] brcmfmac: assure brcmf_txcomplete() is called in
 failure paths

For transmit packets the function brcmf_txcomplete() must be
called. This should be done as well when for some reason the
transmit fails to assure proper tx post processing. This patch
fixes the code paths in brcmf_usb_tx() that forgot to do so.

Subject: [PATCH 0142/1722] brcmfmac: add parameter to brcmf_proto_hdrpush()
 for data offset

The function brcmf_proto_hdrpush() increases the header space and
fills in the protocol header fields. One field is the data offset
which is currently fixed to zero meaning the data follows right
after the header. The parameter is added to determine the actual
start of data. This will be used for firmware signalling.

Subject: [PATCH 0146/1722] ath9k_hw: Fix fixed antenna for AR9462

When the RX chainmask is set to 0x2 for AR9462, certain values
from chain1 have to be programmed for chain0 also.

Subject: [PATCH 0147/1722] b43: HT-PHY: make it BCMA-only
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

HT-PHY was found only on BCM4331 which is a BCMA-based chipset. This is
reallly unlikely we will ever see HT-PHY on SSB thus make the whole code
BCMA specific. This will allow us to call various BCMA-specific

Subject: [PATCH 0153/1722] mwifiex: modify skb->truesize for PCIE Rx

We allocate SKB buffers of 4K size to make sure that we process
RX AMSDU of 4K. So when skb->len is lesser than 4K; we should
modify skb->truesize. This resolves an issue where kernel has
allocated packets with 2K assumption and starts dropping packets
for large size data transfer.

This fix is already present for USB; extend it to PCIE.

Subject: [PATCH 0155/1722] mwifiex: add "ethtool wol" command support

Host sleep wakeup condition is configured using this command.

Supports Wake-on: pumb

For examples:

wake-on any unicast packets:
ethtool -s mlan0 wol u

wake-on multicast/broadcast packet:
ethtool -s mlan0 wol mb

wake-on unicast packets and MAC events:
ethtool -s mlan0 wol pu

wake-on unicast/multicast/broadcast packets and MAC events:
ethtool -s mlan0 wol pmbu

disable all wake-on options:
ethtool -s mlan0 wol d

Subject: [PATCH 0156/1722] mwifiex: add WOWLAN support

Currently 'magic-packet' and 'patterns' options in 'iw wowlan'
command are supported.

Appropriate packet filters for wowlan are configured in firmware
based on provided patterns and/or magic-packet option.

For examples,

wake-on ARP request for 192.168.0.100:
iw phy0 wowlan enable patterns ff:ff:ff:ff:ff:ff 20+08:06
  46+c0:a8:00:64

wake-on RX packets sent from IP address 192.168.0.88:
iw phy0 wowlan enable patterns 34+c0:a8:00:58

wake-on RX packets with TCP destination port 80
iw phy0 wowlan enable patterns 44+50

wake-on MagicPacket:
iw phy0 wowlan enable magic-packet

wake-on MagicPacket or patterns:
iw phy0 wowlan enable magic-packet patterns 12+00:11:22:33:44:55
  18+00:50:43:21

wake-on IPv4 multicast packets:
iw phy0 wowlan enable patterns 01:00:5e

wake-on IPv6 multicast packets:
iw phy0 wowlan enable patterns 33:33

disable all wowlan options
iw phy0 wowlan disable

Subject: [PATCH 0157/1722] mac80211: provide race-free 64-bit traffic counters

Make the TX bytes/packets counters race-free by keeping
them per AC so concurrent TX on queues can't cause lost
or wrong updates. This works since each station belongs
to a single interface. While at it also make the bytes
counters 64-bit.

Subject: [PATCH 0158/1722] mac80211: provide ieee80211_sta_eosp()

The irqsafe version ieee80211_sta_eosp_irqsafe() exists, but
drivers must not mix calls to any irqsafe/non-irqsafe function.
Both ath9k and iwlwifi, the likely first users of this interface,
use non-irqsafe RX/TX/TX status so must also use a non-irqsafe
version of this function. Since no driver uses the _irqsafe()
version, remove that.

Subject: [PATCH 0159/1722] mac80211: Call drv_set_tim only if there is a
 change

It is possible that sta_info_recalc_tim() is called consecutively
without changing the station's tim bit. In such cases there is no
need to call the driver's set_tim() callback.

Subject: [PATCH 0161/1722] sfc: PTP changes to support improved UUID filtering
 mode

There is a long-standing problem with the packet-timestamp matching in
the driver. When a PTP packet is received by the MC, the FPGA
timestamps the packet and the MC sends the timestamp and 6 bytes of
the UUID to the driver. The driver then matches the timestamp against
received packets using the same 6 bytes of UUID.

The problem comes from the choice of which 6 bytes to use. The PTP
spec is slightly contradictory and misleading in one of the two places
where the UUIDs are discussed. From section 7.2.2.2 of the spec, a
PTPD2 UUID can be either a EUI-64 or a EUI-64 constructed from a
EUI-48. The typical ethernet based implementation uses a EUI-64
constructed from a EUI-48. This works by taking the first 3 bytes of
the MAC address of the NIC being used for PTP (the OUI), then
inserting 0xFF, 0xFE, then taking the last 3 bytes of the MAC address
giving
          MAC[0], MAC[1], MAC[2], 0xFF, 0xFE, MAC[3], MAC[4], MAC[5]
The current MC firmware and driver discard the first two bytes of this
UUID and packets are matched against timestamps using bytes 2 to 7 so
there is a small risk that in a deployment of Solarflare PTP NICs used
with other vendors NICs, that a PTP packet could be matched against
the wrong timestamp. This applies to all other organisations whose
third byte of the OUI is 0x53. It's a long list but I notice that it
includes Cisco.

The necessary modifications to use bytes 0-2 and 5-7 of the UUID to
match against are quite small but introduce incompatibility between
older version of the firmware and driver.

When PTP is enabled via SO_TIMESTAMPING specifying PTP V2, the driver
will try to enable PTP in the firmware using the enhanced mode
(above). If the firmware returns an error, the driver will enable PTP
in the firmware using the old mode.

- * rx_alloc_method - RX buffer allocation method
- *
- * This driver supports two methods for allocating and using RX buffers:
- * each RX buffer may be backed by an skb or by an order-n page.
- *
- * When GRO is in use then the second method has a lower overhead,
- * since we don't have to allocate then free skbs on reassembled frames.
- *
- * Values:
- *   - RX_ALLOC_METHOD_AUTO = 0
- *   - RX_ALLOC_METHOD_SKB  = 1
- *   - RX_ALLOC_METHOD_PAGE = 2
- *
- * The heuristic for %RX_ALLOC_METHOD_AUTO is a simple hysteresis count
- * controlled by the parameters below.
- *
- *   - Since pushing and popping descriptors are separated by the rx_queue
- *     size, so the watermarks should be ~rxd_size.
- *   - The performance win by using page-based allocation for GRO is less
- *     than the performance hit of using page-based allocation of non-GRO,
- *     so the watermarks should reflect this.
- *
- * Per channel we maintain a single variable, updated by each channel:
- *
- *   rx_alloc_level += (gro_performed ? RX_ALLOC_FACTOR_GRO :
- *                      RX_ALLOC_FACTOR_SKB)
- * Per NAPI poll interval, we constrain rx_alloc_level to 0..MAX (which
- * limits the hysteresis), and update the allocation strategy:
- *
- *   rx_alloc_method = (rx_alloc_level > RX_ALLOC_LEVEL_GRO ?
- *                      RX_ALLOC_METHOD_PAGE : RX_ALLOC_METHOD_SKB)

Subject: [PATCH 0164/1722] sfc: More sensible semantics for
 efx_filter_insert_filter() replace flag

The 'replace' flag to efx_filter_insert_filter() controls whether the
new filter may replace *any* filter, and is checked even before
priority comparison.  But lower-priority filters should never
block insertion of higher-priority filters.

Change the priority checking so that lower-priority filters are
replaced regardless of the value of the flag, and rename the
flag to 'replace_equal'.

Subject: [PATCH 0166/1722] sfc: Don't use efx_filter_{build,hash,increment}()
 for default MAC filters

These functions happen to work for default MAC filters: they generate
an initial index of 1/0 for unicast/multicast respectively and an
increment of 1 for either, so a search succeeds at depth 2.  But this
is a matter of luck rather than design, and it really won't work well
with the bug fix we're about to do.

efx_filter_search() is only called from efx_filter_insert(), and
neither function is very long.  The following bug fix requires a more
sophisticated search with a third result, which is going to be easier
to implement as part of the same function.

Subject: [PATCH 0168/1722] sfc: Fix replacement detection in
 efx_filter_insert_filter()

efx_filter_insert_filter() uses the first table entry in the hash chain
that either has the same match values or is empty.  This means that
replacement doesn't always work correctly:

1. Insert filter F1 with match values M1, hashing to H1, at first
   possible entry E1.
2. Insert filter F2 with match values M2, hashing to H1, at second
   possible entry E2.
3. Remove filter F1.
4. Insert filter F3 with match values M2, hashing to H1, at first
   possible entry E1.

F3 should have either replaced F2 or been rejected (depending on
priority and the replace_equal parameter).

Instead, search for both a matching filter that the inserted filter
would replace, and an available insertion point, up to the applicable
maximum search depths.  If we insert at lower depth than a replaced
filter, clear the replaced filter.

Subject: [PATCH 0169/1722] sfc: Disable RSS when using SR-IOV and only 1 RX
 queue on the PF

On Siena, VFs share RSS configuration with the PF.  We attempted to
support configurations where the PF only uses 1 RX queue and VFs use
multiple RX queues, by (1) setting up RSS for the number of RX queues
per VF (2) disabling RSS in the PF's RX default filters.

Unfortunately commit cd2d5b529cdb ('sfc: Add SR-IOV back-end support
for SFC9000 family') only included (1).  This is (2).

Subject: [PATCH 0170/1722] sfc: Add AER and EEH support for Siena

The Linux side of EEH is triggered by MMIO reads, but this
driver's data path does not issue any MMIO reads (except in
legacy interrupt mode).  Therefore add a monitor function
to poll EEH periodically.

When preparing to reset the device based on our own error
detection, also poll EEH and defer to its recovery mechanism
if appropriate.

[bwh: Use a separate condition for the initial link poll; fix some
 style errors]

Currently we prefetch from the Ethernet header, but we will also read
the hash prefix.  In practice they should be in the same cache line
and this won't hurt, but it is still pointless to add on the hash
prefix size.

Subject: [PATCH 0178/1722] sfc: Enable RX DMA scattering where possible

Enable RX DMA scattering iff an RX buffer large enough for the current
MTU will not fit into a single page and the NIC supports DMA
scattering for kernel-mode RX queues.

On Falcon and Siena, the RX_USR_BUF_SIZE field is used as the DMA
limit for both all RX queues with scatter enabled.  Set it to 1824,
matching what Onload uses now.

Maintain a statistic for frames truncated due to lack of descriptors
(rx_nodesc_trunc).  This is distinct from rx_frm_trunc which may be
incremented when scattering is disabled and implies an over-length
frame.

Whenever an MTU change causes scattering to be turned on or off,
update filters that point to the PF queues, but leave others
unchanged, as VF drivers assume scattering is off.

Add n_frags parameters to various functions, and make them iterate:
- efx_rx_packet()
- efx_recycle_rx_buffers()
- efx_rx_mk_skb()
- efx_rx_deliver()

Make efx_handle_rx_event() responsible for updating
efx_rx_queue::removed_count.

Change the RX pipeline state to a starting ring index and number of
fragments, and make __efx_rx_packet() responsible for clearing it.

Based on earlier versions by David Riddoch and Jon Cooper.

Subject: [PATCH 0179/1722] sfc: reuse pages to avoid DMA mapping/unmapping
 costs

On POWER systems, DMA mapping/unmapping operations are very expensive.
These changes reduce these costs by trying to reuse DMA mapped pages.

After all the buffers associated with a page have been processed and
passed up, the page is placed into a ring (if there is room).  For
each page that is required for a refill operation, a page in the ring
is examined to determine if its page count has fallen to 1, ie. the
kernel has released its reference to these packets.  If this is the
case, the page can be immediately added back into the RX descriptor
ring, without having to re-map it for DMA.

If the kernel is still holding a reference to this page, it is removed
from the ring and unmapped for DMA.  Then a new page, which can
immediately be used by RX buffers in the descriptor ring, is allocated
and DMA mapped.

The time a page needs to spend in the recycle ring before the kernel
has released its page references is based on the number of buffers
that use this page.  As large pages can hold more RX buffers, the RX
recycle ring can be shorter.  This reduces memory usage on POWER
systems, while maintaining the performance gain achieved by recycling
pages, following the driver change to pack more than two RX buffers
into large pages.

When an IOMMU is not present, the recycle ring can be small to reduce
memory usage, since DMA mapping operations are inexpensive.

With a small recycle ring, attempting to refill the descriptor queue
with more buffers than the equivalent size of the recycle ring could
ultimately lead to memory leaks if page entries in the recycle ring
were overwritten.  To prevent this, the check to see if the recycle
ring is full is changed to check if the next entry to be written is
NULL.

[bwh: Combine and rebase several commits so this is complete
 before the following buffer-packing changes.  Remove module
 parameter.]

Date: Thu, 7 Mar 2013 16:31:17 +0000
Subject: [PATCH 0180/1722] sfc: Replace efx_rx_is_last_buffer() with a flag

This condition is brittle and we have lots of flags to spare.

Subject: [PATCH 0181/1722] sfc: allocate more RX buffers per page

Allocating 2 buffers per page is insanely inefficient when MTU is 1500
and PAGE_SIZE is 64K (as it usually is on POWER).  Allocate as many as
we can fit, and choose the refill batch size at run-time so that we
still always use a whole page at once.

[bwh: Fix loop condition to allow for compound pages; rebase]

Subject: [PATCH 0182/1722] net: generic fdb support for drivers without
 ndo_fdb_<op>

If the driver does not support the ndo_op use the generic
handler for it. This should work in the majority of cases.
Eventually the fdb_dflt_add call gets translated into a
__dev_set_rx_mode() call which should handle hardware
support for filtering via the IFF_UNICAST_FLT flag.

Namely IFF_UNICAST_FLT indicates if the hardware can do
unicast address filtering. If no support is available
the device is put into promisc mode.

Subject: [PATCH 0185/1722] qlcnic: Use generic fdb handler when driver options
 are not enabled.

Allow qlcnic to use the generic fdb handler when the driver options
are not enabled.   Untill the driver is fully fixed, this allows
the use of the FDB interface with qlogic driver, but simply puts
the driver into promisc mode since the driver currently does not
support IFF_UNICAST_FLT.

Subject: [PATCH 0186/1722] tg3: Add new FW_TSO flag

tg3 used the fw_needed member loosely as a synonym for firmware TSO. Now
that the 57766 needs firmware download support, fw_needed can no longer be
used like this. This patch creates a new FW_TSO flag and changes the
code to use it.

Also rearrange all the TSO flags together in the enum.

The 57766 rxcpu needs to be paused/resumed when we download the firmware just
like we do for existing firmware. Refactor the pause/resume code to be
reusable.

This patch also renames the "offset" argument of tg3_halt_cpu to "cpu_base"
since that's what it really is.

Subject: [PATCH 0189/1722] tg3: Cleanup firmware parsing code

The current firmware header parsing is complicated due to interpreting it as a
u32 array and accessing header members via array offsets. Add tg3_firmware_hdr
structure to access the firmware fields instead of hardcoding offsets. The same
header format will be used for individual firmware fragments in the 57766.

The fw_hdr and tg3 structures have all the information required for
loading the fw. Remove the redundant fw_info structure and pass fw_hdr
instead.

From e757e3e198795bfc56a28b41c494bcb27c0ee2ab Mon Sep 17 00:00:00 2001

Subject: [PATCH 0198/1722] ixgbevf: Make next_to_watch a pointer and adjust
 memory barriers to avoid races

This change is meant to address several race issues that become possible
because next_to_watch could possibly be set to a value that shows that the
descriptor is done when it is not.  In order to correct that we instead make
next_to_watch a pointer that is set to NULL during cleanup, and set to the
eop_desc after the descriptor rings have been written.

To enforce proper ordering the next_to_watch pointer is not set until after
a wmb writing the values to the last descriptor in a transmit.  In order to
guarantee that the descriptor is not read until after the eop_desc we use the
read_barrier_depends which is only really necessary on the alpha architecture.

From ce43a2168c59bc47b5f0c1825fd5f9a2a9e3b447 Mon Sep 17 00:00:00 2001
From: Bruce Allan <bruce.w.allan@intel.com>
Date: Wed, 20 Feb 2013 04:06:32 +0000
Subject: [PATCH 0210/1722] e1000e: cleanup USLEEP_RANGE checkpatch checks

Resolve strict checkpatch USLEEP_RANGE checks by converting delays and
sleeps as described in ./Documentation/timers/timers-howto.txt.  Three
other violations of the text have also been fixed.

CHECK:USLEEP_RANGE: usleep_range is preferred over udelay; see
Documentation/timers/timers-howto.txt

As hci_acl_disconn function basically sends the HCI Disconnect Command
and it is used to disconnect ACL, SCO and LE links, renaming it to
hci_disconnect is more suitable.

Subject: [PATCH 0214/1722] Bluetooth: Make hidp_get_raw_report abort if the
 session is terminating

After linux 3.2 the hid_destroy_device call in hidp_session
cleaning up invokes a hook to the power_supply code which
in turn tries to read the battery capacity. This read will
trigger a call to hidp_get_raw_report which is bound to fail
because the device is being taken away - so rather than
wait for the 5 second timeout failure this changes enables
it to fail straight away.

Subject: [PATCH 0215/1722] Bluetooth: discard bt_sock_unregister() errors

After we successfully registered a socket via bt_sock_register() there is
no reason to ever check the return code of bt_sock_unregister(). If
bt_sock_unregister() fails, it means the socket _is_ already unregistered
so we have what we want, don't we?

Also, to get bt_sock_unregister() to fail, another part of the kernel has
to unregister _our_ socket. This is sooo _wrong_ that it will break way
earlier than when we unregister our socket.

Subject: [PATCH 0216/1722] Bluetooth: change bt_sock_unregister() to return
 void

There is no reason a caller ever wants to check the return type of this
call. _Iff_ a user successfully called bt_sock_register(), they're allowed
to call bt_sock_unregister().
All other calls in the kernel (device_del, device_unregister, kfree(), ..)
that are logically equivalent return void. Lets not make callers think
they have to check the return type of this call and instead simply return
void.

We guarantee that after bt_sock_unregister() is called, the socket type
_is_ unregistered. If that is not what the caller wants, they're using the
wrong function, anyway.

Subject: [PATCH 0217/1722] Bluetooth: Avoid rfcomm_session_timeout using freed
 session

Use del_timer_sync() instead of del_timer() as this ensures
that rfcomm_session_timeout() is not running on a different
CPU when rfcomm_session_put() is called. This avoids a race
condition on SMP systems because potentially
rfcomm_session_timeout() could reuse the freed RFCOMM session
structure caused by the execution of rfcomm_session_put().

Note that this modification makes the reason for the RFCOMM
session refcnt mechanism redundant.

Subject: [PATCH 0218/1722] Bluetooth: Check rfcomm session and DLC exists on
 socket close

A race condition exists between near simultaneous asynchronous
DLC data channel disconnection requests from the host and remote device.
This causes the socket layer to request a socket shutdown at the same
time the rfcomm core is processing the disconnect request from the remote
device.

The socket layer retains a copy of a struct rfcomm_dlc d pointer.
The d pointer refers to a copy of a struct rfcomm_session.
When the socket layer thread performs a socket shutdown, the thread
may wait on a rfcomm lock in rfcomm_dlc_close(). This means that
whilst the thread waits, the rfcomm_session and/or rfcomm_dlc structures
pointed to by d maybe freed due to rfcomm core handling. Consequently,
when the rfcomm lock becomes available and the thread runs, a
malfunction could occur as a freed rfcomm_session structure and/or a
freed rfcomm_dlc structure will be erroneously accessed.

Therefore, after the rfcomm lock is acquired, check that the struct
rfcomm_session is still valid by searching the rfcomm session list.
If the session is valid then validate the d pointer by searching the
rfcomm session list of active DLCs for the rfcomm_dlc structure
pointed by d.

Subject: [PATCH 0219/1722] Bluetooth: Return RFCOMM session ptrs to avoid
 freed session

Unfortunately, the design retains local copies of the s RFCOMM
session pointer in various code blocks and this invites the erroneous
access to a freed RFCOMM session structure.

Therefore, return the RFCOMM session pointer back up the call stack
to avoid accessing a freed RFCOMM session structure. When the RFCOMM
session is deleted, NULL is passed up the call stack.

If active DLCs exist when the rfcomm session is terminating,
avoid a memory leak of rfcomm_dlc structures by ensuring that
rfcomm_session_close() is used instead of rfcomm_session_del().

Subject: [PATCH 0220/1722] Bluetooth: Remove RFCOMM session refcnt

Previous commits have improved the handling of the RFCOMM session
timer and the RFCOMM session pointers such that freed RFCOMM
session structures should no longer be erroneously accessed. The
RFCOMM session refcnt now has no purpose and will be deleted by
this commit.

Note that the RFCOMM session is now deleted as soon as the
RFCOMM control channel link is no longer required. This makes the
lifetime of the RFCOMM session deterministic and absolute.
Previously with the refcnt, there was uncertainty about when
the session structure would be deleted because the relative
refcnt prevented the session structure from being deleted at will.

It was noted that the refcnt could malfunction under very heavy
real-time processor loading in embedded SMP environments. This
could cause premature RFCOMM session deletion or double session
deletion that could result in kernel crashes. Removal of the
refcnt prevents this issue.

There are 4 connection / disconnection RFCOMM session scenarios:
host initiated control link ---> host disconnected control link
host initiated ctrl link ---> remote device disconnected ctrl link
remote device initiated ctrl link ---> host disconnected ctrl link
remote device initiated ctrl link ---> remote device disc'ed ctrl link

The control channel connection procedures are independent of the
disconnection procedures. Strangely, the RFCOMM session refcnt was
applying special treatment so erroneously combining connection and
disconnection events. This commit fixes this issue by removing
some session code that used the "initiator" member of the session
structure that was intended for use with the data channels.

Subject: [PATCH 0222/1722] Bluetooth: Remove redundant RFCOMM BT_CLOSED
 settings

rfcomm_session_close() sets the RFCOMM session state to BT_CLOSED.
However, in multiple places immediately before the function is
called, the RFCOMM session is set to BT_CLOSED. Therefore,
remove these unnecessary state settings.

Subject: [PATCH 0224/1722] Bluetooth: Fix __hci_req_sync() handling of empty
 requests

If a request callback doesn't send any commands __hci_req_sync() should
fail imediately instead of waiting for the inevitable timeout to occur.
This is particularly important once we start creating requests with
conditional command sending which can potentially result in no commands
being sent at all.

Subject: [PATCH 0225/1722] Bluetooth: Split HCI init sequence into three
 stages

Having conditional command sending during a request has always been
problematic and caused hacks like the hdev->init_last_cmd variable. This
patch removes these conditionals and instead splits the init sequence
into three stages, each with its own __hci_req_sync() call.

This also paves the way to the upcoming asynchronous request support
swhich will also benefit by having a simpler implementation if it
doesn't need to cater for requests that change on the fly.

Subject: [PATCH 0226/1722] Bluetooth: Add initial skeleton for asynchronous
 HCI requests

This patch adds the initial definitions and functions for asynchronous
HCI requests. Asynchronous requests are essentially a group of HCI
commands together with an optional completion callback. The request is
tracked through the already existing command queue by having the
necessary context information as part of the control buffer of each skb.

The only information needed in the skb control buffer is a flag for
indicating that the skb is the start of a request as well as the
optional complete callback that should be used when the request is
complete (this will be found in the last skb of the request).

This patch moves out the skb creation from hci_send_cmd() into its own
prepare_cmd() function. This is essential so the same prepare_cmd()
function can be easily reused for skb creation for asynchronous HCI
requests.

Subject: [PATCH 0228/1722] Bluetooth: Introduce new hci_req_add function

This function is analogous to hci_send_cmd() but instead of directly
queuing the command to hdev->cmd_q it adds it to the local queue of the
asynchronous HCI request being build (inside struct hci_request).

This is the main function used for building asynchronous requests and
there should be one or more calls to it between calls to hci_req_init
and hci_req_run.

Subject: [PATCH 0229/1722] Bluetooth: Fix stand-alone HCI command handling

To have a consistent content for hdev->cmd_q all entries need to follow
the semantics of asynchronous HCI requests. This means that even single
commands need to be dressed as requests by having a request start
indicator. This patch adds these indicators to the two places needing
it (hci_send_cmd and hci_sock_sendmsg).

Subject: [PATCH 0230/1722] Bluetooth: Add request cmd_complete and cmd_status
 functions

This patch introduces functions to process the HCI request state when
receiving HCI Command Status or Command Complete events. Some HCI
commands, like Inquiry do not result in a Command complete event so
special handling is needed for them. Inquiry is a particularly important
one since it is the only forseeable "non-cmd_complete" command that will
make good use of the request functionality, and its completion is either
indicated by an Inquiry Complete event of a successful Command Complete
for HCI_Inquiry_Cancel.

From 42c6b129cd8c2aa5012a78ec39672e7052cc677a Mon Sep 17 00:00:00 2001

Subject: [PATCH 0231/1722] Bluetooth: Use async requests internally in
 hci_req_sync

This patch converts the hci_req_sync() procedure to internaly use the
asynchronous HCI requests.

The hci_req_sync mechanism relies on hci_req_complete() calls from
hci_event.c into hci_core.c whenever a HCI command completes. This is
very similar to what asynchronous requests do and makes the conversion
fairly straight forward by converting hci_req_complete into a request
complete callback. By this change hci_req_complete (renamed to
hci_req_sync_complete) becomes private to hci_core.c and all calls to it
can be removed from hci_event.c.

The commands in each hci_req_sync procedure are collected into their own
request by passing the hci_request pointer to the request callback
(instead of the hci_dev pointer). The one slight exception is the HCI
init request which has the special handling of HCI driver specific
initialization commands. These commands are run in their own request
prior to the "main" init request.

One other extra change that this patch must contain is the handling of
spontaneous HCI reset complete events that some controllers exhibit.
These were previously handled in the hci_req_complete function but the
right place for them now becomes the hci_req_cmd_complete function.

Subject: [PATCH 0232/1722] Bluetooth: Remove unused hdev->init_last_cmd

This variable is no longer needed (due to async HCI request support and
the conversion of hci_req_sync to use it), so it can be safely removed.

Subject: [PATCH 0233/1722] Bluetooth: Remove empty HCI event handlers

With the removal of hci_req_complete() several HCI event handlers have
essentially become empty and can be removed. The only potential benefit
of these could have been logging, but the hci_event, hci_cmd_complete
and hci_cmd_status already provide a log for events which they do not
have an explicit handler for.

Subject: [PATCH 0234/1722] VSOCK: Split vm_sockets.h into kernel/uapi

Split the vSockets header into kernel and UAPI parts.  The former gets the bits
that used to be in __KERNEL__ guards, while the latter gets everything that is
user-visible.  Tested by compiling vsock (+transport) and a simple user-mode
vSockets application.

From: Hannes Frederic Sowa <hannes@stressinduktion.org>
Date: Fri, 8 Mar 2013 02:07:16 +0000
Subject: [PATCH 0236/1722] ipv6: introdcue __ipv6_addr_needs_scope_id and
 ipv6_iface_scope_id helper functions

__ipv6_addr_needs_scope_id checks if an ipv6 address needs to supply
a 'sin6_scope_id != 0'. 'sin6_scope_id != 0' was enforced in case
of link-local addresses. To support interface-local multicast these
checks had to be enhanced and are now consolidated into these new helper
functions.

v2:
a) migrated to struct ipv6_addr_props

v3:
a) reverted changes for ipv6_addr_props
b) test for address type instead of comparing scope

v4:
a) unchanged

From: Hannes Frederic Sowa <hannes@stressinduktion.org>
Date: Fri, 8 Mar 2013 02:07:19 +0000
Subject: [PATCH 0237/1722] ipv6: use newly introduced
 __ipv6_addr_needs_scope_id and ipv6_iface_scope_id

This patch requires multicast interface-scoped addresses to supply a
sin6_scope_id. Because the sin6_scope_id is now also correctly used
in case of interface-scoped multicast traffic this enables one to use
interface scoped addresses over interfaces which are not targeted by the
default multicast route (the route has to be put there manually, though).

getsockname() and getpeername() now return the correct sin6_scope_id in
case of interface-local mc addresses.

v2:
a) rebased ontop of patch 1/4 (now uses ipv6_addr_props)

v3:
a) reverted changes for ipv6_addr_props

v4:
a) unchanged

Subject: [PATCH 0240/1722] mwifiex: Trigger a card reset on reaching
 tx_timeout threshold

tx_timeout doesn't always lead to a cmd_timeout. There are
occurrences where cmd_timeout never gets triggered for a long
time and we encounter a kernel crash. In this patch, we track
the consecutive timeouts (tx_timeout_cnt). When tx_timeout_cnt
exceeds the threshold, trigger a card reset thereby avoiding a
kernel crash.

Subject: [PATCH 0243/1722] Bluetooth: Fix __hci_req_sync

If hci_req_run returns error, we erroneously leave the current
process in TASK_INTERRUPTABLE state. If we leave the process in
TASK_INTERRUPTABLE and it is preempted, this process will never
be scheduled again.

This patch fixes this issue by moving the preparation for scheduling
(add to waitqueue and set process state) to just after the hci_req_run
call.

Since hci_req_run will be returning more than one error code, we
should check its returning value in __hci_req_sync.

Subject: [PATCH 0246/1722] Bluetooth: HCI request error handling

When we are building a HCI request with more than one HCI command
and one of the hci_req_add calls fail, we should have some cleanup
routine so the HCI commands already queued on HCI request can be
deleted. Otherwise, we will face some memory leaks issues.

This patch implements the HCI request error handling which is the
following: If a hci_req_add fails, we save the error code in hci_
request. Once hci_req_run is called, we verify the error field. If
it is different from zero, we delete all HCI commands already queued
and return the error code.

Since no one checks the returning value of hci_req_add and HCI
request errors are now handled in hci_req_run, we can make hci_
req_add returning void.

Subject: [PATCH 0249/1722] Bluetooth: Fix endianness handling of
 cmd_status/complete opcodes

The opcode in cmd_complete and cmd_status events is 16 bits, so we
should only be comparing it after having converted it to the host
endianness. There's already an opcode variable in both functions which
is in host endiannes so the right fix is to just start using it instead
of ev->opcode.

Subject: [PATCH 0250/1722] net: Kill link between CSUM and SG features.

Earlier SG was unset if CSUM was not available for given device to
force skb copy to avoid sending inconsistent csum.
Commit c9af6db4c11c (net: Fix possible wrong checksum generation)
added explicit flag to force copy to fix this issue.  Therefore
there is no need to link SG and CSUM, following patch kills this
link between there two features.

This patch is also required following patch in series.

Subject: [PATCH 0253/1722] tunneling: Capture inner mac header during
 encapsulation.

This patch adds inner mac header. This will be used in next patch
to find tunner header length. Header len is required to copy tunnel
header to each gso segment.
This patch does not change any functionality.

From 731362674580cb0c696cd1b1a03d8461a10cf90a Mon Sep 17 00:00:00 2001

Date: Thu, 7 Mar 2013 13:21:51 +0000
Subject: [PATCH 0254/1722] tunneling: Add generic Tunnel segmentation.

Adds generic tunneling offloading support for IPv4-UDP based
tunnels.
GSO type is added to request this offload for a skb.
netdev feature NETIF_F_UDP_TUNNEL is added for hardware offloaded
udp-tunnel support. Currently no device supports this feature,
software offload is used.

This can be used by tunneling protocols like VXLAN.

From: Joe Perches <joe@perches.com>
Date: Fri, 8 Mar 2013 15:03:25 +0000
Subject: [PATCH 0266/1722] drivers:net: Remove unnecessary OOM messages after
 netdev_alloc_skb

Emitting netdev_alloc_skb and netdev_alloc_skb_ip_align OOM
messages is unnecessary as there is already a dump_stack
after allocation failures.

Other trivial changes around these removals:

Convert a few comparisons of pointer to 0 to !pointer.
Change flow to remove unnecessary label.
Remove now unused variable.
Hoist assignment from if.

Subject: [PATCH 0269/1722] tunnel: use iptunnel_xmit() again

With recent patches from Pravin, most tunnels can't use iptunnel_xmit()
any more, due to ip_select_ident() and skb->ip_summed. But we can just
move these operations out of iptunnel_xmit(), so that tunnels can
use it again.

This by the way fixes a bug in vxlan (missing nf_reset()) for net-next.

Subject: [PATCH 0271/1722] ipv6: introduce ip6tunnel_xmit() helper

Similar to iptunnel_xmit(), group these operations into a
helper function.

This by the way fixes the missing u64_stats_update_begin()
and u64_stats_update_end() for 32 bit arch.

tw_cookie_values is never used in the TCP-stack.

It was added by 435cf559f (TCPCT part 1d: define TCP cookie option,
extend existing struct's), but already at that time it was not used at
all, nor mentioned in the commit-message.

They really are remote peer parameters, and we need to distinguish them
from the local ones as we'll modify the latter with socket options.

Subject: [PATCH 0279/1722] NFC: llcp: Implement socket options

Some LLCP services (e.g. the validation ones) require some control over
the LLCP link parameters like the receive window (RW) or the MIU extension
(MIUX). This can only be done through socket options.

Subject: [PATCH 0284/1722] NFC: llcp: Service Name Lookup SDRES aggregation

This modifies the way SDRES PDUs are sent back. If multiple SDREQs are
received within a single SNL PDU, all SDRES replies are sent packed in
one SNL PDU too.

Subject: [PATCH 0285/1722] NFC: llcp: Service Name Lookup netlink interface

This adds a netlink interface for service name lookup support.
Multiple URIs can be passed nested into the NFC_ATTR_LLC_SDP attribute
using the NFC_CMD_LLC_SDREQ netlink command.
When the SNL reply is received, a NFC_EVENT_LLC_SDRES event is sent to
the user space. URI and SAP tuples are passed back, nested into
NFC_ATTR_LLC_SDP attribute.

Subject: [PATCH 0286/1722] NFC: llcp: Add cleanup support for unreplied SNL
 requests

If the remote LLC doesn't reply in time to our SNL requests we remove
them from the list of pending requests. The timeout is fixed to an
arbitrary value of 3 times remote_lto.

When not replied, the local LLC broadcasts NFC_EVENT_LLC_SDRES nl events for
the concerned uris with sap values set to LLCP_SDP_UNBOUND (which is 65).

Subject: [PATCH 0288/1722] mac80211: clean up key freeing a bit

When a key is allocated but not really added, there's no
need to go through the entire teardown process. Also, if
adding a key fails, ieee80211_key_link() can take care of
freeing it instead of the (only) caller.

Subject: [PATCH 0290/1722] mac80211: batch key free synchronize_net()

Instead of calling synchronize_net() for every key
on an interface or when a station is removed, do it
only once for all keys in both of these cases.

As a side-effect, removing station keys now always
calls synchronize_net() even if there are no keys,
which fixes an issue with station removal happening
in the driver while the station could still be used
for TX.

Subject: [PATCH 0292/1722] mac80211: add driver callback for per-interface
 multicast filter

Some devices have multicast filter capability for each individual
virtual interface rather than just a global one. Add an interface
specific driver callback allowing such drivers to configure this.

Subject: [PATCH 0296/1722] mwl8k: don't overwrite regulatory settings on fw
 reload

Currently the caps are parsed on every firmware reload, causing any
channel flags to be cleared.
When there is a firmware to interface mode mismatch, the triggered
firmware reload causes a reset of the regulatory settings, causing all
channels to become available:

root@openrouter:/# iw phy phy0 info
Wiphy phy0
        Band 1:
		(...)
                Frequencies:
                        * 2412 MHz [1] (0.0 dBm)

                        * 2422 MHz [3] (0.0 dBm)
                        * 2427 MHz [4] (0.0 dBm)

                        * 2442 MHz [7] (0.0 dBm)
                        * 2447 MHz [8] (0.0 dBm)
                        * 2452 MHz [9] (0.0 dBm)
                        * 2457 MHz [10] (0.0 dBm)
                        * 2462 MHz [11] (0.0 dBm)
                        * 2467 MHz [12] (0.0 dBm)
                        * 2472 MHz [13] (0.0 dBm)
                        * 2484 MHz [14] (0.0 dBm)
		(...)

To prevent this, only parse the caps on the first firmware load during
hardware probe, and store them locally to know we have already parsed
them.

Subject: [PATCH 0299/1722] phy/micrel: move flag handling to function for
 common use

The flag MICREL_PHY_50MHZ_CLK is not of exclusive use of KSZ8051
model. At least KSZ8021 and KSZ8031 models also use it.
This patch moves the handling of this and future flags to a
separate function so that the different PHY models can call it on
their init function, if needed.

Subject: [PATCH 0302/1722] bnx2x: Set ethtool ops for vfs

Virtual functions don't have access to HW registers, therefore most ethtool ops
are forbidden to them. Instead of checking in each op whether the device being
driven is a virtual function or a physical function, this patch creates a
separate ethtool ops struct for virtual functions and uses it to initialize
the ethtool ops of the driver in case it is driving a virtual function device.

From 6ba8a3b19e764b6a65e4030ab0999be50c291e6c Mon Sep 17 00:00:00 2001
From: Nandita Dukkipati <nanditad@google.com>
Date: Mon, 11 Mar 2013 10:00:43 +0000
Subject: [PATCH 0320/1722] tcp: Tail loss probe (TLP)

This patch series implement the Tail loss probe (TLP) algorithm described
in http://tools.ietf.org/html/draft-dukkipati-tcpm-tcp-loss-probe-01. The
first patch implements the basic algorithm.

TLP's goal is to reduce tail latency of short transactions. It achieves
this by converting retransmission timeouts (RTOs) occuring due
to tail losses (losses at end of transactions) into fast recovery.
TLP transmits one packet in two round-trips when a connection is in
Open state and isn't receiving any ACKs. The transmitted packet, aka
loss probe, can be either new or a retransmission. When there is tail
loss, the ACK from a loss probe triggers FACK/early-retransmit based
fast recovery, thus avoiding a costly RTO. In the absence of loss,
there is no change in the connection state.

PTO stands for probe timeout. It is a timer event indicating
that an ACK is overdue and triggers a loss probe packet. The PTO value
is set to max(2*SRTT, 10ms) and is adjusted to account for delayed
ACK timer when there is only one oustanding packet.

TLP Algorithm

On transmission of new data in Open state:
  -> packets_out > 1: schedule PTO in max(2*SRTT, 10ms).
  -> packets_out == 1: schedule PTO in max(2*RTT, 1.5*RTT + 200ms)
  -> PTO = min(PTO, RTO)

Conditions for scheduling PTO:
  -> Connection is in Open state.
  -> Connection is either cwnd limited or no new data to send.
  -> Number of probes per tail loss episode is limited to one.
  -> Connection is SACK enabled.

When PTO fires:
  new_segment_exists:
    -> transmit new segment.
    -> packets_out++. cwnd remains same.

  no_new_packet:
    -> retransmit the last segment.
       Its ACK triggers FACK or early retransmit based recovery.

ACK path:
  -> rearm RTO at start of ACK processing.
  -> reschedule PTO if need be.

In addition, the patch includes a small variation to the Early Retransmit
(ER) algorithm, such that ER and TLP together can in principle recover any
N-degree of tail loss through fast recovery. TLP is controlled by the same
sysctl as ER, tcp_early_retrans sysctl.
tcp_early_retrans==0; disables TLP and ER.
		 ==1; enables RFC5827 ER.
		 ==2; delayed ER.
		 ==3; TLP and delayed ER. [DEFAULT]
		 ==4; TLP only.

The TLP patch series have been extensively tested on Google Web servers.
It is most effective for short Web trasactions, where it reduced RTOs by 15%
and improved HTTP response time (average by 6%, 99th percentile by 10%).
The transmitted probes account for <0.5% of the overall transmissions.

From 9b717a8d245075ffb8e95a2dfb4ee97ce4747457 Mon Sep 17 00:00:00 2001
From: Nandita Dukkipati <nanditad@google.com>
Date: Mon, 11 Mar 2013 10:00:44 +0000
Subject: [PATCH 0321/1722] tcp: TLP loss detection.

This is the second of the TLP patch series; it augments the basic TLP
algorithm with a loss detection scheme.

This patch implements a mechanism for loss detection when a Tail
loss probe retransmission plugs a hole thereby masking packet loss
from the sender. The loss detection algorithm relies on counting
TLP dupacks as outlined in Sec. 3 of:
http://tools.ietf.org/html/draft-dukkipati-tcpm-tcp-loss-probe-01

The basic idea is: Sender keeps track of TLP "episode" upon
retransmission of a TLP packet. An episode ends when the sender receives
an ACK above the SND.NXT (tracked by tlp_high_seq) at the time of the
episode. We want to make sure that before the episode ends the sender
receives a "TLP dupack", indicating that the TLP retransmission was
unnecessary, so there was no loss/hole that needed plugging. If the
sender gets no TLP dupack before the end of the episode, then it reduces
ssthresh and the congestion window, because the TLP packet arriving at
the receiver probably plugged a hole.

Subject: [PATCH 0322/1722] phy: add set_wol/get_wol functions

This allows ethernet drivers (such as the mv643xx_eth) to support
Wake on LAN on platforms where PHY registers have to be configured
for Wake on LAN (e.g. the Marvell Kirkwood based qnap TS-119P II).

Subject: [PATCH 0323/1722] mv643xx_eth with 88E1318S: support Wake on LAN

This has been tested on a qnap TS-119P II. Note that enabling WOL with
"ethtool -s eth0 wol g" is not enough; you also need to tell the PIC
microcontroller inside the qnap that WOL should be enabled by sending
0xF2 with qcontrol(1) and you have to disable EUP ("Energy-using
Products", a European power-saving thing) by sending 0xF4.

Subject: [PATCH 0334/1722] firewire net: No need to reset dev->local_fifo
 after failure of fw_core_add_address_handler().

fwnet_broadcast_start() try to register address handler at first
if it was not registered yet; dev->local_fifo ==
FWNET_NO_FIFO_ADDR.

Since dev->local_info not changed if fw_core_add_address_hander()
has failed, we do not need to set dev->local_info to
FWNET_NO_FIFO_ADDR.

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since commit e565275 entitled "ssb: pci: Standardize a function to get mac
address", the SPROM readout of the MAC has had the values flipped so that
00:11:22:33:44:55 became 11:00:33:22:55:44. The fix has been tested on both
little- and big-endian architectures.

On the DMG band, there is no 'normal' beacon frame.
Instead, transmitted is short 'DMG beacon' frame, that do not include IE's
So, beacon IE's are not relevant for the DMG band.

user space get notified through kobject_uevent_env(), that might sleep and thus
should run in thread context.

Move user space notification to the thread handler, while mark FW is non-functional
right in the hard IRQ.

Subject: [PATCH 0360/1722] wil6210: new SW reset

New firmware allows for shorter SW reset procedure.
After SW reset, FW raises "fw done" IRQ, at this
moment mailbox control structures are initialized, driver caches it.

New status bit wil_status_reset_done introduced to track completion
of the reset. It is set by "fw ready" irq, and required for WMI rx flow
to access control structures.

WMI Tx flow protected by other status bit, wil_status_fwready. It can't
be set before wil_status_reset_done is set by design.

Subject: [PATCH 0361/1722] wil6210: sync with new firmware

Adjust driver for changes in the FW API.
Noticeable changes in the FW are:
- temperature sensing
- infrastructure for multiple connections
- infrastructure for P2P
- signal strength indication

This commit introduces only changes that are required to support same functionality
as previous firmware, no new features.

Subject: [PATCH 0363/1722] b43: HT-PHY: rename AFE defines
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

It you take a look at N-PHY analog switch function it touches every core
on the chipset. It seems HT-PHY does they same, it just has 3 cores
instead of 2 (which make sense since BCM4331 is 3x3). Rename AFE defines
to include core id.

Content-Transfer-Encoding: 8bit

After comparing operations on reg 0xB on N and HT it seems to be the
same register with similar ops. Implement them for HT-PHY.

Subject: [PATCH 0365/1722] b43: HT-PHY: move TX fix to the separated function
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On N-PHY after B43_PHY_B_TEST operation there is a call to TX power fix
function which iterates over available cores. It matches our HT-PHY code
which means it's probably also some TX fix.

On N-PHY it's also done after TX power fix, so it was easy to spot.
Unfortunately the MMIO logs I have from ndsiwrapper include channels
1-12 only, so enabling code for 13 and 14 is just a N-PHY-based guess.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Don't enable it until we have (almost?) whole TX power management
figured out. It's similar to the N-PHY, the difference is that we call a
"fix" *before* disabling power control.

 playback
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

It was another sequence I recognized in HT-PHY dump:
 phy_read(0x00c7) -> 0x0001
 phy_read(0x00c3) -> 0x0000
phy_write(0x00c3) <- 0x0002
 phy_read(0x00c3) -> 0x0000
phy_write(0x00c3) <- 0x0000
The difference to N-PHY is that it writes to 6 tables instead of a one
(after above).

Subject: [PATCH 0376/1722] batman-adv: replace redundant primary_if_get calls

The batadv_priv struct carries a pointer to its own interface
struct. Therefore, it is not necessary to retrieve the soft_iface
via the primary interface.

Subject: [PATCH 0379/1722] batman-adv: network coding - add the initial
 infrastructure code
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Network coding exploits the 802.11 shared medium to allow multiple
packets to be sent in a single transmission. In brief, a relay can XOR
two packets, and send the coded packet to two destinations. The
receivers can decode one of the original packets by XOR'ing the coded
packet with the other original packet. This will lead to increased
throughput in topologies where two packets cross one relay.

In a simple topology with three nodes, it takes four transmissions
without network coding to get one packet from Node A to Node B and one
from Node B to Node A:

 1.  Node A  ---- p1 --->  Node R                Node B
 2.  Node A                Node R  <--- p2 ----  Node B
 3.  Node A  <--- p2 ----  Node R                Node B
 4.  Node A                Node R  ---- p1 --->  Node B

With network coding, the relay only needs one transmission, which saves
us one slot of valuable airtime:

 1.  Node A  ---- p1 --->  Node R                Node B
 2.  Node A                Node R  <--- p2 ----  Node B
 3.  Node A  <- p1 x p2 -  Node R  - p1 x p2 ->  Node B

The same principle holds for a topology including five nodes. Here the
packets from Node A and Node B are overheard by Node C and Node D,
respectively. This allows Node R to send a network coded packet to save
one transmission:

   Node A                  Node B

    |     \              /    |
    |      p1          p2     |
    |       \          /      |
    p1       > Node R <       p2
    |                         |
    |         /      \        |
    |    p1 x p2    p1 x p2   |
    v       /          \      v
           /            \
   Node C <              > Node D

More information is available on the open-mesh.org wiki[1].

This patch adds the initial code to support network coding in
batman-adv. It sets up a worker thread to do house keeping and adds a
sysfs file to enable/disable network coding. The feature is disabled by
default, as it requires a wifi-driver with working promiscuous mode, and
also because it adds a small delay at each hop.

Subject: [PATCH 0380/1722] batman-adv: network coding - detect coding nodes
 and remove these after timeout
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

To use network coding efficiently, a relay must know when neighbor nodes
are likely to have enough information to be able to decode a network
coded packet. This is detected by using OGMs from batman-adv to discover
when one neighbor is in range of another neighbor. The relay check the
TLL to detect when an OGM is forwarded from one neighbor by another
neighbor, and thereby knows that the two neighbors are in range and thus
overhear packets sent by each other.

This information is saved in the orig_node struct to be used when
searching for coding opportunities. Two lists are added to the
orig_node struct: One for neighbors that can hear the orig_node
(outgoing nc_nodes) and one for neighbors that the orig_node can hear
(incoming nc_nodes).

Information about nc_nodes is kept for 10 seconds and is available
through debugfs in batman_adv/nc_nodes to use when debugging network
coding.

Subject: [PATCH 0381/1722] batman-adv: network coding - buffer unicast packets
 before forward
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two be able to network code two packets, one packet must be buffered
until the next is available. This is done in a "coding buffer", which is
essentially a hash table with lists of packets. Each entry in the hash
table corresponds to a specific src-dst pair, which has a linked list of
packets that are buffered.

This patch adds skbs to the buffer just before forwarding them. The
buffer is traversed every 10 ms, where timed skbs are removed from the
buffer and transmitted. To allow experiments with the network coding
scheme, the timeout is tunable through a file in debugfs.

Subject: [PATCH 0382/1722] batman-adv: network coding - code and transmit
 packets if possible
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Before adding forward-skbs to the coding buffer, the buffer is searched
for a potential coding opportunity. If one is found, the two packets are
network coded and transmitted right away. If not, the forward-skb is
added to the buffer.

Network coded packets are transmitted with information about the two
receivers and the two coded packets. The first receiver is given by the
MAC header, while the second is given in the payload/bat-header. The
second receiver uses promiscuous mode to receive the packet and check
the second destination.

Subject: [PATCH 0383/1722] batman-adv: network coding - save overheard and tx
 packets for decoding
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

To be able to decode a network coded packet, a node must already know
one of the two coded packets. This is done by buffering skbs before
transmission and buffering packets sniffed with promiscuous mode from
other hosts.

Packets are kept in a buffer similar to the one with forward-skbs: A
hash table, where each entry, which corresponds to a src-dst pair, has a
linked list packets.

Subject: [PATCH 0384/1722] batman-adv: network coding - receive coded packets
 and decode them
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When receiving a network coded packet, the decoding buffer is searched
for a packet to use for decoding. The source, destination, and crc32 from
the coded packet is used to identify the wanted packet. The decoded
packet is passed to the usual unicast receiver function, as had it never
been network coded.

Subject: [PATCH 0389/1722] cxgb4: Add T5 write combining support

This patch implements a low latency Write Combining (aka Write Coalescing) work
request path. PCIE maps User Space Doorbell BAR2 region writes to the new
interface to SGE. SGE pulls a new message from PCIE new interface and if its a
coalesced write work request then pushes it for processing. This patch copies
coalesced work request to memory mapped BAR2 space.

Subject: [PATCH 0394/1722] cxgb4: Disable SR-IOV support for PF4-7 for T5

All T5 adapters will only support VFs on PF0-3 despite the ability of the
hardware to support them on PF4-7.  This keeps our T4 and T5 adapters more
similar which simplifies host driver software.

Subject: [PATCH 0399/1722] RDMA/cxgb4: Use DSGLs for fastreg and adapter
 memory writes for T5.

It enables direct DMA by HW to memory region PBL arrays and fast register PBL
arrays from host memory, vs the T4 way of passing these arrays in the WR itself.
The result is lower latency for memory registration, and larger PBL array
support for fast register operations.

This patch also updates ULP_TX_MEM_WRITE command fields for T5. Ordering bit of
ULP_TX_MEM_WRITE is at bit position 22 in T5 and at 23 in T4.

Subject: [PATCH 0402/1722] RDMA/cxgb4: Fix onchip queue support for T5

T5 adapter does not support onchip queue memory. Present logic fails to
allocate QP for T5 and returns an error. Also, if module parameter ocqp_support
is zero then we are unable to allocate QP which should not be the case. Ideally
if ocqp_support parameter is 0 or onchip queue support is disable then host QP
should be allocated before returning an error.

From d69630e8a42220b04318995d8ed0637ea79a717e Mon Sep 17 00:00:00 2001
From: Arvind Bhushan <arvindb@chelsio.com>
Date: Thu, 14 Mar 2013 05:09:07 +0000
Subject: [PATCH 0405/1722] csiostor: Header file modifications for chip
 support and bug fixes.

This patch defines the common operations to support multiple chips. It
includes common header file modifications to support the current chips
(T4 and T5). It also includes the following bug fixes:
- reconfirms the rnode state after an implicit logo.
- corrects the stats array size.
- sets up and checks flags correctly when coming up as master and finding
the card initialized

Subject: [PATCH 0411/1722] netfilter: ebt_ulog: remove unnecessary spin lock
 protection

No need for spinlock to protect the netlink skb in the
ebt_ulog_fini path. We are sure there is noone using it
at that stage.

Subject: [PATCH 0413/1722] netxen: write IP address to firmware when using
 bonding

This patch allows LRO aggregation on bonded devices that contain an
NX3031 device. It also adds a for_each_netdev_in_bond_rcu(bond, slave)
macro which executes for each slave that has bond as master.

V3: After testing and discussing this with Rajesh, I decided to keep the
    vlan ip cache and just rename it to ip_cache since it will store bond
    ip addresses too. A new master flag has been added to the ip cache to
    denote that the address has been added because of a master device.
    I've taken care of the enslave/release cases by checking for various
    combinations of events and flags (e.g. netxen has a master, it's a
    bond master and it's not marked as a slave means it is being enslaved
    and is dev_open()ed in bond_enslave).
    I've changed netxen_free_ip_list() to have a "master" parameter which
    causes all IP addresses marked as master to be deleted (used when a
    netxen is being released). I've made the patch use the new upper
    device API as well. The following cases were tested:
    - bond -> netxen
    - vlan -> netxen
    - vlan -> bond -> netxen

V2: Remove local ip caching, retrieve addresses dynamically and
    restore them if necessary.

Note: Tested with NX3031 adapter.

Subject: [PATCH 0414/1722] VSOCK: Support VM sockets connected to the
 hypervisor.

The resource ID used for VM socket control packets (0) is already
used for the VMCI_GET_CONTEXT_ID hypercall so a new ID (15) must be
used when the guest sends these datagrams to the hypervisor.

The hypervisor context ID must also be removed from the internal
blacklist.

Subject: [PATCH 0415/1722] net: clean leftover of COMPAT_NET_DEV_OPS removal

COMPAT_NET_DEV_OPS was removed a while back and with it the definition of
netdev_resync_ops() went away. Let's finish the clean-up.

Subject: [PATCH 0416/1722] be2net: enable interrupts in be_probe() (RoCE and
 other ULPs need them)

As the NIC PCI function may be used by other protocols, the chip interrupts
must be enabled in be_probe() itself rather than be_open().

Subject: [PATCH 0418/1722] drivers:net: Remove dma_alloc_coherent OOM messages

I believe these error messages are already logged
on allocation failure by warn_alloc_failed and so
get a dump_stack on OOM.

Remove the unnecessary additional error logging.

Around these deletions:

o Alignment neatening.
o Remove unnecessary casts of dma_alloc_coherent.
o Hoist assigns from ifs.

Subject: [PATCH 0422/1722] bluetooth: btmrvl_sdio: look for sd8688 firmware in
 proper location

The firmware images are shared with libertas_sdio WiFi chip and used to be
in libertas/ subtree in linux-firmware. As btmrvl_sdio used to look into
the linux-firmware root, it ended up being unsuccessful. Since the
firmware files are not specific to the libertas hardware, they're being
moved into mrvl/ now.

Subject: [PATCH 0423/1722] caif: remove caif_shm

caif_shm is an old implementation
caif_shm will be replaced by caif_virtio

[ As explained by Linus Walleij: "U5500 used this, but was cancelled
  and the silicon did not reach anyone outside ST-Ericsson.  Then for
  the next platforms, we have gone for the leaner & cleaner approach
  of using virtio, rpmesg and rproc." ]

Subject: [PATCH 0424/1722] vxlan: generalize forwarding tables

This patch generalizes VXLAN forwarding table entries allowing an administrator
to:
	1) specify multiple destinations for a given MAC
	2) specify alternate vni's in the VXLAN header
	3) specify alternate destination UDP ports
	4) use multicast MAC addresses as fdb lookup keys
	5) specify multicast destinations
	6) specify the outgoing interface for forwarded packets

The combination allows configuration of more complex topologies using VXLAN
encapsulation.

Changes since v1: rebase to 3.9.0-rc2

From 1f9061d27d3d2028805549c4a306324a48209057 Mon Sep 17 00:00:00 2001

Subject: [PATCH 0426/1722] drivers:net: dma_alloc_coherent: use __GFP_ZERO
 instead of memset(, 0)

Reduce the number of calls required to alloc
a zeroed block of memory.

Trivially reduces overall object size.

Other changes around these removals
o Neaten call argument alignment
o Remove an unnecessary OOM message after dma_alloc_coherent failure
o Remove unnecessary gfp_t stack variable

Subject: [PATCH 0430/1722] tcp: Remove TCPCT

TCPCT uses option-number 253, reserved for experimental use and should
not be used in production environments.
Further, TCPCT does not fully implement RFC 6013.

As a nice side-effect, removing TCPCT increases TCP's performance for
very short flows:

Doing an apache-benchmark with -c 100 -n 100000, sending HTTP-requests
for files of 1KB size.

before this patch:
	average (among 7 runs) of 20845.5 Requests/Second
after:
	average (among 7 runs) of 21403.6 Requests/Second

Subject: [PATCH 0433/1722] ath6kl: fix usb related error handling and warnings

It was annoying to debug usb warm reboot initialisation problems as many usb
related functions just ignored errors and it wasn't obvious from the kernel
logs what was failing. Fix all that so that error messages are printed and
errors are handled properly.

Subject: [PATCH 0434/1722] ath6kl: cold reset target after host warm boot

Julien reported that ar6004 usb device fails to initialise
after host has been rebooted and power is still on for the ar6004 device. He
found out that doing a cold reset fixes the issue.

I wasn't sure what would be the best way to detect if target needs a reset so I
settled on checking a timeout from htc_wait_recv_ctrl_message().

Subject: [PATCH 0437/1722] ath6kl: add tracing point for hif irqs

Add a tracing point for hif irq and dump the register content to user space.
This is in hif.c as we could use the same code also with SPI but, as ath6kl
doesn't SPI and most likely never will be, this is used just by SDIO so
name the trace point as ath6kl_sdio_irq to make it easier to manage filters.

Subject: [PATCH 0438/1722] ath6kl: adding tracing points for htc_mbox

Add tracing points for htc layer, just dumping the packets to user space.
I wasn't really sure what to do with the status value, it might not always
be accurate, but I included it anyway.

I skipped htc_pipe (and usb) implementation for now. Need to add those
tracepoints later.

Subject: [PATCH 0441/1722] ath6kl: add tracing support to debug message macros

Now all log messages are sent through the tracing infrastruture as well.
Tracing point doesn't follow debug_mask module parameter, instead it sends
all debug messages, so once you enable ath6kl_log_dbg tracing point you will
get a lot of messages. Needs to be discussed if this is sensible or not.
The overhead should be small enough and we anyway include debug level as
well so it's easy to filter in user space.

I wasn't really sure what to do with ath6kl_dbg_dump() and for now decided
that it also sends the buffer to user space. But most likely in the future
ath6kl_dbg_dump() should go away in favor of using proper tracing points, but
we will see.

Subject: [PATCH 0442/1722] ath6kl: add an extra band check to
 ath6kl_wmi_beginscan_cmd()

Dan reported that smatch found a possible issue in ath6kl_wmi_beginscan_cmd()
where we might access sc->supp_rates beyond the end. It shouldn't happen as
ar->wiphy->bands always have just the first two bands set, but add an extra
check just to be sure.

Subject: [PATCH 0443/1722] ath6kl: remove false check from ath6kl_rx()

Dan found a check from ath6kl_rx() which doesn't make any sense at all:

"  1327          if (status || !(skb->data + HTC_HDR_LENGTH)) {
                                ^^^^^^^^^^^^^^^^^^^^^^^^^^
skb->data is a pointer.  This pointer math is always going to be false.
Should it be testing "packet->act_len < HTC_HDR_LENGTH" or something?"

I don't know what the check really was supposed to do, but I think Dan's guess
is right. Fix it accordingly.

Subject: [PATCH 0444/1722] ath6kl: Fix the byte alignment rule to avoid loss
 of bytes in a TCP segment

Either first 3 bytes of the first received tcp segment or last one
over MTU size file can be loss due to the byte alignment problem.
Although ATH6KL_HTC_ALIGN_BYTES was defined for 'extra bytes for htc header
alignment' in the patch "Fix buffer alignment for scatter-gather
I/O"(1df94a857), there exists the bytes loss issue which means that it will be
truncated 3 bytes in the transmitted file contents if a file which has over MTU
size is transferred through TCP/IP stack.  It doesn't look like TCP/IP stack
bug of 3.5 or the latest version of kernel but the byte alignment issue.  This
patch is to use the roundup() function for the byte alignment rather than the
predefined ATH6KL_HTC_ALIGN_BYTES.

Subject: [PATCH 0450/1722] Bluetooth: Update mgmt powered HCI commands to use
 async requests

This patch updates sending of HCI commands related to mgmt_set_powered
(e.g. class, name and EIR data) to be sent using asynchronous requests.
This is necessary since it's the only (well, at least the cleanest) way
to keep the power on procedure synchronized and let user space know it
has completed only when all HCI commands are completed (this actual fix
is coming in a subsequent patch).

Subject: [PATCH 0451/1722] Bluetooth: Wait for HCI command completion with
 mgmt_set_powered

We should only notify user space that the adapter has been powered on
after all HCI commands related to the action have completed. This patch
fixes the issue by instating an async request complete callback for
these HCI commands and only notifies user space in the callback.

Subject: [PATCH 0452/1722] Bluetooth: Fix busy condition testing for EIR and
 class updates

The add/remove_uuid and set_dev_class mgmt commands can trigger both EIR
and class HCI commands, so testing just for a pending class command is
enough. The simplest way to monitor conflicts that should trigger "busy"
error returns is to check for any pending mgmt command that can trigger
these HCI commands. This patch adds a helper function for this
(pending_eir_or_class) and uses it instead of the old HCI_PENDING_CLASS
flag to test for busy conditions.

Subject: [PATCH 0453/1722] Bluetooth: Fix UUID/class mgmt command response
 synchronization

We should only return a mgmt command complete once all HCI commands to a
mgmt_set_dev_class or mgmt_add/remove_uuid command have completed. This
patch fixes the issue by having a proper async request complete callback
for these actions and responding to user space in the callback.

When powering off the device the hdev->flags and hdev->dev_flags need to
be cleared before calling mgmt_powered(). If this is not done the
resulting events sent to user space may contain incorrect values.

Note that the HCI_AUTO_OFF flag accessed right after this is part of the
persistent flags, so it's unchanged by the hdev->dev_flags reset.

Subject: [PATCH 0458/1722] Bluetooth: Fix waiting for EIR update when setting
 local name

We shouldn't respond to the mgmt_set_local_name command until all
related HCI commands have completed. This patch fixes the issue by
running the local name HCI command and the EIR update in the same
asynchronous request, and returning the mgmt command complete through
the complete callback of the request.

The downside of this is that we must set hdev->dev_name before the local
name HCI command has completed since otherwise the generated EIR
command doesn't contain the new name. This means that we can no-longer
reliably detect when the name has really changed and when not. Luckily
this only affects scenarios where the mgmt interface is *not* used (e.g.
hciconfig) so redundant mgmt_ev_local_name_changed events in these cases
are an acceptable drawback.

Subject: [PATCH 0459/1722] Bluetooth: Handle AD updating through an async
 request

For proper control of the AD update and the related HCI commands it's
best to run the AD update through an async request instead of a
standalone HCI command. This patch changes the hci_update_ad() function
to take a request pointer and updates its users appropriately. E.g. the
function is no longer called after the init sequence but during stage 3
of the init sequence.

The TX power is read during the init sequence, so we don't need an
explicit update whenever it is read and the AD update based on the local
name should be done through the local name mgmt handler. The only other
user is the update based on enabling advertising. This part is still
kept as there is no mgmt API to enable it.

data should only be sent for BR/EDR capable controllers whereas an
update to the AD should only happen for LE capable controllers.

Subject: [PATCH 0465/1722] Bluetooth: Fix error response for simultaneous fast
 connectable commands

If there's another pending mgmt_set_fast_connectable command we should
return a "busy" error response.

Subject: [PATCH 0466/1722] Bluetooth: Add proper flag for fast connectable
 mode

In order to be able to represent fast connectable mode in the mgmt
settings we need to have a HCI dev flag for it. This patch adds the flag
and makes sure its value is changed whenever a mgmt_set_fast_connectable
command completes.

 connectable

When the connectable setting is disabled the fast connectable setting
must also be disabled. This is so that we're consistent with the
pre-requisites for enabling fast connectable, one of which is that the
connectable setting is enabled.

Subject: [PATCH 0476/1722] Bluetooth: Add reading of page scan parameters

These parameters are related to the "fast connectable" mode that can be
changed through the mgmt interface. Not all controllers properly reset
these values with HCI_Reset so they need to be read in order to be able
to verify whether the values are correct or not before enabling page
scan.

 successful write commands

The page scan parameters (interval, window and type) stored in struct
hci_dev should not only be updated after successful reads but also after
successful writes. This patch adds the necessary handlers for the write
command complete events and updates the stored values through them.

Subject: [PATCH 0479/1722] Bluetooth: Fix fast connectable state when enabling
 page scan

When powering on or enabling page scan we need to ensure that the page
scan parameters are as they should be. This is because some controllers
do not properly reset these values upon HCI_Reset. Since the
write_scan_parameters function is now called from several new places it
also checks for the >= 1.2 HCI version requirement before sending the
commands.

Subject: [PATCH 0482/1722] mac80211: move sdata debugfs dir to vif

There is need create driver own per interface debugfs files. This is
currently done by drv_{add,remove}_interface_debugfs() callbacks. But it
is possible that after we remove interface from the driver (i.e.
on suspend) we call drv_remove_interface_debugfs() function. Fixing this
problem will require to add call drv_{add,remove}_interface_debugfs()
anytime we create and remove interface in mac80211. So it's better to
add debugfs dir dentry to vif structure to allow to create/remove
custom debugfs driver files on drv_{add,remove}_interface().

Subject: [PATCH 0483/1722] mac80211: remove vif debugfs driver callbacks

This basically reverts commit b207cdb07f3f01ec1adaac62e9d0cc918c60a81a.

Now is possible to use drv_{add,remove}_interface() and vif->debugfs_dir
to create/remove per interface debugfs files. Remove redundant
callbacks.

Subject: [PATCH 0484/1722] mac80211/minstrel_ht: improve rate selection
 stability

Under load, otherwise stable rates can easily fluctuate because of
collisions. In my tests on a clean channel, the success probability of
the max throughput rate often stays somewhere between 90% and 100% under
load. This can cause some unnecessary switching to lower rates.
This patch improves stability by treating success probability values
between 90% and 100% the same.
In my tests on a 3x3 HT20 link with lots of TCP traffic, it improves the
average throughput by a few mbit/s.

Subject: [PATCH 0485/1722] mac80211/minstrel_ht: avoid useless sampling of
 high-probability slower rates

Slow rates that have >95% success probability do not need to be
monitored continuously. When the channel conditions change rapidly, the
slow sampling results are useless anyway. When conditions change slowly,
they will be monitored by gradual downgrading of the actively used
rates. This patch slightly improves throughput under good conditions.

There are a number of situations in which mac80211 only
really needs to flush queues for one virtual interface,
and in fact during this frames might be transmitted on
other virtual interfaces. Calculate and pass a queue
bitmap to the driver so it knows which queues to flush.

From 445ea4e83ec50668cc9ad7e5cf96d242f19165e8 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Wed, 13 Feb 2013 12:25:28 +0100
Subject: [PATCH 0488/1722] mac80211: stop queues temporarily for flushing

Sometimes queues are flushed in the middle of
operation, which can lead to driver issues.
Stop queues temporarily, while flushing, to
avoid transmitting new packets while they are
being flushed.

Subject: [PATCH 0489/1722] mwifiex: cleanup VHT cap

Firmware returned VHT cap has the same format that cfg80211
expects. There is no need to parse the vht cap from the firmware
and then set it to ieee80211_sta_vht_cap. Just copying is
sufficient.

Subject: [PATCH 0491/1722] rt2x00: Fix tx status reporting for reordered
 frames in rt2800pci

rt2800 hardware sometimes reorders tx frames when transmitting to
multiple BA enabled STAs concurrently.

For example a tx queue
	[ STA1 | STA2 | STA1 | STA2 ]
can result in the tx status reports
	[ STA1 | STA1 | STA2 | STA2 ]
when the hw decides to put the frames for STA1 in one AMPDU.

To mitigate this effect associate the currently processed tx status
to the first frame in the tx queue with a matching wcid.

This patch fixes several problems related to incorrect tx status
reporting. Furthermore the tx rate selection is much more stable when
communicating with multiple STAs.

Subject: [PATCH 0496/1722] rt2800: 5592: MAC registers initalization

Based on:
NICInitRT5592MacRegisters()

from:
DPO_RT5572_LinuxSTA_2.6.1.3_20121022/chips/rt5592.c

On vendor driver we do not initialize TX_SW_CFG{1,2}. However the same
difference is between rt2x00 and vendor driver for 5390 chip.

NICInitRT5592RFRegisters()
RF5592Reg_2G_5G[]

from:
DPO_RT5572_LinuxSTA_2.6.1.3_20121022/chips/rt5592.c

This patch also merge common frequency adjustment (RF_R17 settings)
code. Further work is needed, to setup more RF/BBP/MAC registers after
that.

Subject: [PATCH 0520/1722] can: dump stack on protocol bugs

The rework of the kernel hlist implementation "hlist: drop the node parameter
from iterators" (b67bfe0d42cac56c512dd5da4b1b347a23f4b70a) created some
fallout in the form of non matching comments and obsolete code.

Additionally to the cleanup this patch adds a WARN() statement to catch the
caller of the wrong filter removal request.

Subject: [PATCH 0526/1722] xfrm: use xfrm direction when lookup policy

because xfrm policy direction has same value with corresponding
flow direction, so this problem is covered.

In xfrm_lookup and __xfrm_policy_check, flow_cache_lookup is used to
accelerate the lookup.

Flow direction is given to flow_cache_lookup by policy_to_flow_dir.

When the flow cache is mismatched, callback 'resolver' is called.

'resolver' requires xfrm direction,
so convert direction back to xfrm direction.

Subject: [PATCH 0528/1722] netfilter: nfnetlink_queue: zero copy support

nfqnl_build_packet_message() actually copy the packet
inside the netlink message, while it can instead use
zero copy.

Make sure the skb 'copy' is the last component of the
cooked netlink message, as we cant add anything after it.

Patch cooked in Copenhagen at Netfilter Workshop ;)

Still to be addressed in separate patches :

-GRO/GSO packets are segmented in nf_queue()
and checksummed in nfqnl_build_packet_message().

Proper support for GSO/GRO packets (no segmentation,
and no checksumming) needs application cooperation, if we
want no regressions.

Subject: [PATCH 0530/1722] netfilter: nf_conntrack: speed up module removal
 path if netns in use

The patch introduces nf_conntrack_cleanup_net_list(), which cleanups
nf_conntrack for a list of netns and calls synchronize_net() only once
for them all. This should reduce netns destruction time.

I've measured cleanup time for 1k dummy net ns. Here are the results:

 <without the patch>
 # modprobe nf_conntrack
 # time modprobe -r nf_conntrack

 real	0m10.337s
 user	0m0.000s

 <with the patch>
 # modprobe nf_conntrack
 # time modprobe -r nf_conntrack

Subject: [PATCH 0532/1722] packet: packet fanout rollover during socket
 overload

Changes:
  v3->v2: rebase (no other changes)
          passes selftest
  v2->v1: read f->num_members only once
          fix bug: test rollover mode + flag

Minimize packet drop in a fanout group. If one socket is full,
roll over packets to another from the group. Maintain flow
affinity during normal load using an rxhash fanout policy, while
dispersing unexpected traffic storms that hit a single cpu, such
as spoofed-source DoS flows. Rollover breaks affinity for flows
arriving at saturated sockets during those conditions.

The patch adds a fanout policy ROLLOVER that rotates between sockets,
filling each socket before moving to the next. It also adds a fanout
flag ROLLOVER. If passed along with any other fanout policy, the
primary policy is applied until the chosen socket is full. Then,
rollover selects another socket, to delay packet drop until the
entire system is saturated.

Probing sockets is not free. Selecting the last used socket, as
rollover does, is a greedy approach that maximizes chance of
success, at the cost of extreme load imbalance. In practice, with
sufficiently long queues to absorb bursts, sockets are drained in
parallel and load balance looks uniform in `top`.

To avoid contention, scales counters with number of sockets and
accesses them lockfree. Values are bounds checked to ensure
correctness.

Tested using an application with 9 threads pinned to CPUs, one socket
per thread and sufficient busywork per packet operation to limits each
thread to handling 32 Kpps. When sent 500 Kpps single UDP stream
packets, a FANOUT_CPU setup processes 32 Kpps in total without this
patch, 270 Kpps with the patch. Tested with read() and with a packet
ring (V1).

Also, passes psock_fanout.c unit test added to selftests.

Subject: [PATCH 0535/1722] iwlwifi: mvm: MVM op_mode is supported on 7000 only

The code removed in this patch was used for bring up on
older NICs. No MVM capable fw will ever be released for
older NICs, so remove that code.

Subject: [PATCH 0536/1722] iwlwifi: mvm: suppress key error messages in AP
 mode

In AP mode, don't attempt to program GTKs into the
device, they're used for TX only so not needed and
programming them causes error messages. Also, in
this case and if key programming fails, avoid trying
to remove the key that isn't present later.

Subject: [PATCH 0539/1722] cfg80211: fix potential connection work crash

If wpa_supplicant and iw/iwconfig are used together, very
rarely the system crashes. It seems to be related to the
connection parameters not being set up, but it's not all
clear to me how this happens. In any case, checking that
the conn pointer exists here is probably a good idea.

Subject: [PATCH 0541/1722] iwlwifi: mvm: fix the {ack,cts}_kill_msk

The masks were wrong. They should be 0xffffffff when SCO,
HID or SNIFF profiles are used. They should be 0xffff0000
in any other case (default) to get a bit more throughput
when the BT profile allows for it.

Fix a debug print on the way.

This data should taken from TLVs and not from the NVM. This
is true for the value written in CSR_HW_IF_CONFIG_REG too.

Also, no need to set the CSR_HW_IF_CONFIG_REG_BIT_MAC_SI bit
for 7000 devices which are the only devices currently
supported.

Subject: [PATCH 0554/1722] iwlwifi: mvm: Increase the max remain on channel
 time

Increase the maximal remain on channel time as longer remain
on channel requests are handled by the FW using fragmented
time events.

This reduces the number of user/kernel space iterations during
flows such as p2p_listen. In addition it is currently required
for flows which require longer duration such as p2p_sd.

Subject: [PATCH 0556/1722] net: fix psock_fanout selftest hash collision

Fix flaky results with PACKET_FANOUT_HASH depending on whether the
two flows hash into the same packet socket or not.

Also adds tests for PACKET_FANOUT_LB and PACKET_FANOUT_CPU and
replaces the counting method with a packet ring.

Subject: [PATCH 0558/1722] filter: add ANC_PAY_OFFSET instruction for loading
 payload start offset

It is very useful to do dynamic truncation of packets. In particular,
we're interested to push the necessary header bytes to the user space and
cut off user payload that should probably not be transferred for some reasons
(e.g. privacy, speed, or others). With the ancillary extension PAY_OFFSET,
we can load it into the accumulator, and return it. E.g. in bpfc syntax ...

        ld #poff        ; { 0x20, 0, 0, 0xfffff034 },
        ret a           ; { 0x16, 0, 0, 0x00000000 },

... as a filter will accomplish this without having to do a big hackery in
a BPF filter itself. Follow-up JIT implementations are welcome.

Thanks to Eric Dumazet for suggesting and discussing this during the
Netfilter Workshop in Copenhagen.

Subject: [PATCH 0560/1722] gianfar: Fix tx napi polling

There are 2 issues with the current napi poll routine, with regards
to tx ring cleanup:
1) for multi-queue devices (MQ_MG_MODE), should tx_bit_map != rx_bit_map,
which is possible (and supported in h/w) if the DT property "fsl,tx-bit-map"
holds a different value than rx_bit_map, the current polling routine will
service the wrong Tx queues in this case (i.e. the interrupt group will
receive interrupts from tx queues that it will not service)
2) Tx cleanup completion consumes napi budget, whereas the napi budget
should be reserved for Rx work only.

The patch fixes these issues and provides a clean napi polling routine.
Napi poll completion is reached when all the Rx queues have been
serviced and there is no Tx work to do.

Subject: [PATCH 0561/1722] gianfar: Poll only active Rx queues

Split the napi budget fairly among the active queues only, instead
of dividing it by the total number of Rx queues assigned to the
given interrupt group.
Use the h/w indication field RXFi in rstat (receive status register)
to identify the active rx queues from the current interrupt group
(i.e. receive event occured on ring i, if ring i is part of the current
interrupt group). This indication field in rstat, RXFi i=0..7,
allows us to find out on which queues of the same interrupt group
do we have incomming traffic once we entered the polling routine for
the given interrupt group. After servicing the ring i, the corresponding
bit RXFi will be written with 1 to clear the active queue indication for
that ring.

For Multi Q Multi Group (MQ_MG_MODE) mode, the Rx/Tx colescing registers [rt]xic
are aliased with the [rt]xic0 registers (coalescing setting regs for Q0). This
avoids programming twice in a row the coalescing registers for the Rx/Tx hw Q0.

Subject: [PATCH 0563/1722] gianfar: Refactor config coalescing calls for all
 queues

The only place where gfar_configure_coalescing is called
with an actual bitmask (other than 0xff) is in gfar_poll
(on the hot path). So make gfar_configure_coalescing()
static for the buffer processing path, and export
gfar_configure_coalescing_all() for the remaining cases
that require to set coalescing for all the queues at once
(on the slow path).

Subject: [PATCH 0564/1722] connector: Added coredumping event to the process
 connector

Process connector can now also detect coredumping events.

Main aim of patch is get notified at start of coredumping, instead of
having to wait for it to finish and then being notified through EXIT
event.

Could be used for instance by process-managers that want to get
notified as soon as possible about process failures, and not
necessarily beeing notified after coredump, which could be in the
order of minutes depending on size of coredump, piping and so on.

Subject: [PATCH 0573/1722] dynticks: avoid flow_cache_flush() interrupting
 every core

Previously, if you did an "ifconfig down" or similar on one core, and
the kernel had CONFIG_XFRM enabled, every core would be interrupted to
check its percpu flow list for items that could be garbage collected.

With this change, we generate a mask of cores that actually have any
percpu items, and only interrupt those cores.  When we are trying to
isolate a set of cpus from interrupts, this is important to do.

Subject: [PATCH 0574/1722] chelsio: add headroom in RX path

Drivers should reserve some headroom in skb used in receive path,
to avoid future head reallocation.

One possible way to do that is to use dev_alloc_skb() instead
of alloc_skb(), so that NET_SKB_PAD bytes are reserved.

Subject: [PATCH 0579/1722] filter: add minimal BPF JIT image disassembler

This is a minimal stand-alone user space helper, that allows for debugging or
verification of emitted BPF JIT images. This is in particular useful for
emitted opcode debugging, since minor bugs in the JIT compiler can be fatal.
The disassembler is architecture generic and uses libopcodes and libbfd.

How to get to the disassembly, example:

  1) `echo 2 > /proc/sys/net/core/bpf_jit_enable`
  2) Load a BPF filter (e.g. `tcpdump -p -n -s 0 -i eth1 host 192.168.20.0/24`)
  3) Run e.g. `bpf_jit_disasm -o` to disassemble the most recent JIT code output

`bpf_jit_disasm -o` will display the related opcodes to a particular instruction
as well. Example for x86_64:

$ ./bpf_jit_disasm
94 bytes emitted from JIT compiler (pass:3, flen:9)
ffffffffa0356000 + <x>:
   0:	push   %rbp
   1:	mov    %rsp,%rbp
   4:	sub    $0x60,%rsp
   8:	mov    %rbx,-0x8(%rbp)
   c:	mov    0x68(%rdi),%r9d
  10:	sub    0x6c(%rdi),%r9d

Subject: [PATCH 0580/1722] tcp: refactor F-RTO

The patch series refactor the F-RTO feature (RFC4138/5682).

This is to simplify the loss recovery processing. Existing F-RTO
was developed during the experimental stage (RFC4138) and has
many experimental features.  It takes a separate code path from
the traditional timeout processing by overloading CA_Disorder
instead of using CA_Loss state. This complicates CA_Disorder state
handling because it's also used for handling dubious ACKs and undos.
While the algorithm in the RFC does not change the congestion control,
the implementation intercepts congestion control in various places
(e.g., frto_cwnd in tcp_ack()).

The new code implements newer F-RTO RFC5682 using CA_Loss processing
path.  F-RTO becomes a small extension in the timeout processing
and interfaces with congestion control and Eifel undo modules.
It lets congestion control (module) determines how many to send
independently.  F-RTO only chooses what to send in order to detect
spurious retranmission. If timeout is found spurious it invokes
existing Eifel undo algorithms like DSACK or TCP timestamp based
detection.

The first patch removes all F-RTO code except the sysctl_tcp_frto is
left for the new implementation.  Since CA_EVENT_FRTO is removed, TCP
westwood now computes ssthresh on regular timeout CA_EVENT_LOSS event.

- * Otherwise (basically on duplicate ACK), RTO was (likely) caused by a loss
- * and TCP falls back to conventional RTO recovery. F-RTO allows overriding
- * of Nagle, this is done using frto_counter states 2 and 3, when a new data

- * SACK version:
- *   on first step, wait until first cumulative ACK arrives, then move to
- *   the second step. In second step, the next ACK decides.

- * F-RTO is implemented (mainly) in four functions:
- *   - tcp_use_frto() is used to determine if TCP is can use F-RTO
- *   - tcp_enter_frto() prepares TCP state on RTO if F-RTO is used, it is
- *     called when tcp_use_frto() showed green light
- *   - tcp_process_frto() handles incoming ACKs during F-RTO algorithm
- *   - tcp_enter_frto_loss() is called if there is not enough evidence

From ab42d9ee3d215ab74a49818ffc53771a88ce7ddf Mon Sep 17 00:00:00 2001
From: Yuchung Cheng <ycheng@google.com>
Date: Wed, 20 Mar 2013 13:32:59 +0000
Subject: [PATCH 0581/1722] tcp: refactor CA_Loss state processing

Consolidate all of TCP CA_Loss state processing in
tcp_fastretrans_alert() into a new function called tcp_process_loss().
This is to prepare the new F-RTO implementation in the next patch.

From e33099f96d99c391b3325caa9c44258de04aae86 Mon Sep 17 00:00:00 2001

Subject: [PATCH 0582/1722] tcp: implement RFC5682 F-RTO

This patch implements F-RTO (foward RTO recovery):

When the first retransmission after timeout is acknowledged, F-RTO
sends new data instead of old data. If the next ACK acknowledges
some never-retransmitted data, then the timeout was spurious and the
congestion state is reverted.  Otherwise if the next ACK selectively
acknowledges the new data, then the timeout was genuine and the
loss recovery continues. This idea applies to recurring timeouts
as well. While F-RTO sends different data during timeout recovery,
it does not (and should not) change the congestion control.

The implementaion follows the three steps of SACK enhanced algorithm
(section 3) in RFC5682. Step 1 is in tcp_enter_loss(). Step 2 and
3 are in tcp_process_loss().  The basic version is not supported
because SACK enhanced version also works for non-SACK connections.

The new implementation is functionally in parity with the old F-RTO
implementation except the one case where it increases undo events:
In addition to the RFC algorithm, a spurious timeout may be detected
without sending data in step 2, as long as the SACK confirms not
all the original data are dropped. When this happens, the sender
will undo the cwnd and perhaps enter fast recovery instead. This
additional check increases the F-RTO undo events by 5x compared
to the prior implementation on Google Web servers, since the sender
often does not have new data to send for HTTP.

Note F-RTO may detect spurious timeout before Eifel with timestamps
does so.

budget_per_q won't be used uninitialized since the only time

Subject: [PATCH 0587/1722] gianfar: Remove superfluous kernel_dropped local
 counter

The GRO_DROP return code is handled by the core network layer.
The current kernel approach is to factorize this kind of statistics into
the upper layers, instead of having all the drivers maintaining them.

Subject: [PATCH 0589/1722] netlink: Diag core and basic socket info dumping
 (v2)

The netlink_diag can be built as a module, just like it's done in
unix sockets.

The core dumping message carries the basic info about netlink sockets:
family, type and protocol, portis, dst_group, dst_portid, state.

Groups can be received as an optional parameter NETLINK_DIAG_GROUPS.

Netlink sockets cab be filtered by protocols.

The socket inode number and cookie is reserved for future per-socket info
retrieving. The per-protocol filtering is also reserved for future by
requiring the sdiag_protocol to be zero.

The file /proc/net/netlink doesn't provide enough information for
dumping netlink sockets. It doesn't provide dst_group, dst_portid,
groups above 32.

v2: fix NETLINK_DIAG_MAX. Now it's equal to the last constant.

Subject: [PATCH 0590/1722] net: fix psock_fanout on sparc64

The packetsocket fanout test uses a packet ring. Use TPACKET_V2
instead of TPACKET_V1 to work around a known 32/64 bit issue in
the older ring that manifests on sparc64.

Subject: [PATCH 0591/1722] sh_eth: use PIR_* bits

sh_mdio_init() uses the bare numbers instead of the PHY interface bits, despite
these are declared in sh_eth.h as 'enum PIR_BIT'...

Subject: [PATCH 0592/1722] sh_eth: kill unneeded typecast in
 sh_eth_drv_probe()

sh_eth_drv_probe() does cast from 'void *' when assigning to the 'pd'  variable
which is automatic anyway. Turn the assignment into initializer, while removing
the cast...

Subject: [PATCH 0593/1722] sh_eth: use managed device API

Switch the driver to the managed device API by replacing ioremap() calls with
devm_ioremap_resource() (that will also result in calling request_mem_region()
which the driver forgot to do until now) and k[mz]alloc() with devm_kzalloc() --
this permits to simplify driver's probe()/remove() method cleanup. We can now
remove the ioremap() error messages since the error messages are printed by
 devm_ioremap_resource() itself. We can also remove the 'bitbang' field from
'struct sh_eth_private' as we don't need it anymore in order to free the memory
behind it...

Subject: [PATCH 0594/1722] filter: bpf_jit_comp: refactor and unify BPF JIT
 image dump output

If bpf_jit_enable > 1, then we dump the emitted JIT compiled image
after creation. Currently, only SPARC and PowerPC has similar output
as in the reference implementation on x86_64. Make a small helper
function in order to reduce duplicated code and make the dump output
uniform across architectures x86_64, SPARC, PPC, ARM (e.g. on ARM
flen, pass and proglen are currently not shown, but would be
interesting to know as well), also for future BPF JIT implementations
on other archs.

Subject: [PATCH 0607/1722] net: mvmdio: allow platform device style
 registration

This patch changes the mvmdio driver not to use device tree
helper functions such as of_mdiobus_register() and of_iomap() so we can
instantiate this driver using a classic platform_device approach. Use
the device manager helper to ioremap() the base register cookie so we
get automatic freeing upon error and removal. This change is harmless
for Device Tree platforms because they will get the driver be registered
the same way as it was before.

 error/done interrupts

This patch enhances the "mvmdio" to support a SMI error/done interrupt
line which can be used along with a wait queue instead of doing
busy-waiting on the registers. This is a feature which is available in
the mv643xx_eth SMI code and thus reduces again the gap between the two.

Subject: [PATCH 0610/1722] mv643xx_eth: convert to use the Marvell Orion MDIO
 driver

This patch converts the Marvell MV643XX ethernet driver to use the
Marvell Orion MDIO driver. As a result, PowerPC and ARM platforms
registering the Marvell MV643XX ethernet driver are also updated to
register a Marvell Orion MDIO driver. This driver voluntarily overlaps
with the Marvell Ethernet shared registers because it will use a subset
of this shared register (shared_base + 0x4 to shared_base + 0x84). The
Ethernet driver is also updated to look up for a PHY device using the
Orion MDIO bus driver.

For ARM and PowerPC we register a single instance of the "mvmdio" driver
in the system like it used to be done with the use of the "shared_smi"
platform_data cookie on ARM.

Note that it is safe to register the mvmdio driver only for the "ge00"
instance of the driver because this "ge00" interface is guaranteed to
always be explicitely registered by consumers of
arch/arm/plat-orion/common.c and other instances (ge01, ge10 and ge11)
were all pointing their shared_smi to ge00. For PowerPC the in-tree
Device Tree Source files mention only one MV643XX ethernet MAC instance
so the MDIO bus driver is registered only when id == 0.

From 58d7d8f9b20ee6f883532b952f246e4289fe06eb Mon Sep 17 00:00:00 2001
From: Thomas Graf <tgraf@suug.ch>
Date: Thu, 21 Mar 2013 07:45:28 +0000
Subject: [PATCH 0611/1722] decnet: Parse netlink attributes on our own

decnet is the only subsystem left that is relying on the global
netlink attribute buffer rta_buf. It's horrible design and we
want to get rid of it.

This converts all of decnet to do implicit attribute parsing. It
also gets rid of the error prone struct dn_kern_rta.

Yes, the fib_magic() stuff is not pretty.

It's compiled tested but I need someone with appropriate hardware
to test the patch since I don't have access to it.

From 661d2967b3f1b34eeaa7e212e7b9bbe8ee072b59 Mon Sep 17 00:00:00 2001
From: Thomas Graf <tgraf@suug.ch>
Date: Thu, 21 Mar 2013 07:45:29 +0000
Subject: [PATCH 0612/1722] rtnetlink: Remove passing of attributes into
 rtnl_doit functions

With decnet converted, we can finally get rid of rta_buf and its
computations around it. It also gets rid of the minimal header
length verification since all message handlers do that explicitly
anyway.

o Due to improper data type of variable "type", interrupt resources were
  not getting deleted in hardware which was causing resource exhaustion
  in hardware. Hence mailbox command fails after some iterations of context change.

Subject: [PATCH 0619/1722] ioat/dca: Update DCA BIOS workarounds to use
 TAINT_FIRMWARE_WORKAROUND

This patch is meant to be a follow-up for a patch originally submitted under
the title "ioat: Do not enable DCA if tag map is invalid".  It was brought to
my attention that the preferred approach for BIOS workarounds is to set the
taint flag for TAINT_FIRMWARE_WORKAROUND for systems that require BIOS
workarounds.

This change makes it so that the DCA workarounds for broken BIOSes will now
use WARN_TAINT_ONCE(1, TAINT_FIRMWARE_WORKAROUND, ...) instead of just
printing a message via dev_err.

 device

The mvmdio driver can be instantiated using device tree or as a classic
platform device.  In order to load the driver automatically by udev in
the latter case, the driver needs to define a module alias for the
platform device.

 driver not loaded

When both the Marvell MV643XX ethernet driver and the Orion MDIO driver
are compiled as modules, the ethernet driver may be probed before the
MDIO driver.  Let mv643xx_eth_probe() return EPROBE_DEFER in this case,
i.e. when it cannot find the PHY.

This patch takes benefit of dev_addr_genid and dev_base_seq to check if a change
occurs during a netlink dump. If a change is detected, the flag NLM_F_DUMP_INTR
is set in the first message after the dump was interrupted.

Note that seq and prev_seq must be reset between each family in rtnl_dump_all()
because they are specific to each family.

This patch adds a dev_addr_genid for IPv6. The goal is to use it, combined with
dev_base_seq to check if a change occurs during a netlink dump.
If a change is detected, the flag NLM_F_DUMP_INTR is set in the first message
after the dump was interrupted.

Note that only dump of unicast addresses is checked (multicast and anycast are
not checked).

also renamed ip4_frag_ecn_table to ip_frag_ecn_table.

Hello!

After patch 1 got accepted to net-next I will also send a patch to
netfilter-devel to make the corresponding changes to the netfilter
reassembly logic.

Thanks,

Subject: [PATCH 0627/1722] dsa: add device tree bindings to register DSA
 switches

This patch adds support for registering DSA switches using Device Tree
bindings. Note that we support programming the switch routing table even
though no in-tree user seems to require it. I tested this on Armada 370
with a Marvell 88E6172 (not supported by mainline yet).

+Marvell Distributed Switch Architecture Device Tree Bindings
+------------------------------------------------------------
+
+Required properties:
+- compatible		: Should be "marvell,dsa"
+- #address-cells	: Must be 2, first cell is the address on the MDIO bus
+			  and second cell is the address in the switch tree.
+			  Second cell is used only when cascading/chaining.
+- #size-cells		: Must be 0
+- dsa,ethernet		: Should be a phandle to a valid Ethernet device node
+- dsa,mii-bus		: Should be a phandle to a valid MDIO bus device node
+
+Optionnal properties:
+- interrupts		: property with a value describing the switch
+			  interrupt number (not supported by the driver)
+
+A DSA node can contain multiple switch chips which are therefore child nodes of
+the parent DSA node. The maximum number of allowed child nodes is 4
+(DSA_MAX_SWITCHES).
+Each of these switch child nodes should have the following required properties:
+
+- reg			: Describes the switch address on the MII bus
+- #address-cells	: Must be 1
+- #size-cells		: Must be 0
+
+A switch may have multiple "port" children nodes
+
+Each port children node must have the following mandatory properties:
+- reg			: Describes the port address in the switch
+- label			: Describes the label associated with this port, special
+			  labels are "cpu" to indicate a CPU port and "dsa" to
+			  indicate an uplink/downlink port.
+
+Note that a port labelled "dsa" will imply checking for the uplink phandle
+described below.
+
+Optionnal property:
+- link			: Should be a phandle to another switch's DSA port.
+			  This property is only used when switches are being
+			  chained/cascaded together.
+
+Example:
+
+	dsa@0 {
+		compatible = "marvell,dsa";
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		interrupts = <10>;
+		dsa,ethernet = <&ethernet0>;
+		dsa,mii-bus = <&mii_bus0>;
+
+		switch@0 {
+			#address-cells = <1>;
+			#size-cells = <0>;
+			reg = <16 0>;	/* MDIO address 16, switch 0 in tree */
+
+			port@0 {
+				reg = <0>;
+				label = "lan1";
+			};
+
+			port@1 {
+				reg = <1>;
+				label = "lan2";
+			};
+
+			port@5 {
+				reg = <5>;
+				label = "cpu";
+			};
+
+			switch0uplink: port@6 {
+				reg = <6>;
+				label = "dsa";
+				link = <&switch1uplink>;
+			};
+		};
+
+		switch@1 {
+			#address-cells = <1>;
+			#size-cells = <0>;
+			reg = <17 1>;	/* MDIO address 17, switch 1 in tree */
+
+			switch1uplink: port@0 {
+				reg = <0>;
+				label = "dsa";
+				link = <&switch0uplink>;
+			};
+		};
+	};

When neither IFF_BRIDGE nor IFF_BRIDGE_PORT is set,
and afspec == NULL but  protinfo != NULL, we run into
"if (err == 0) br_ifinfo_notify(RTM_NEWLINK, p);" with
random value in ret.

Thanks to Sergei for pointing out the error in commit comments.

Subject: [PATCH 0632/1722] wlcore: fix link count in single-link-PSM
 optimization

commit 144614f3eebd7d only allowed a single active link when
turning on the optimization, ignoring the fact that an AP has two
additional global links.
Use 3 links as an indication for a single active link. Use the
FW PSM bits to verify the extra active link belongs to the AP role.

Subject: [PATCH 0634/1722] wlcore: consolidate tx_seq handling on recovery

Accumulate the total number of sent packets per-link to find out how far
the encryption sequence number has progressed. Use this number as the
initial security sequence number after recovery.

This consolidates security sequence handling for both chip families, as
we no longer have to rely on 12xx specific Tx completion.

A fortunate side effect of this is correct management of seq numbers for
AP roles and multi-role scenarios.

When a link is removed we save the last seq number on a persistent part
of the wlvif. This helps the data survive through recoveries/suspends,
which also entail changes in the hlid of the link.

This functionality is STA only currently.

For STA we report beacon loss to higher levels so that wpa_s
can attempt to roam without disconnecting. In case of P2P CLI
we don't want to attempt roaming and instead disconnect immediately
upon beacon loss.

Subject: [PATCH 0641/1722] wlcore: correctly check state before regdomain conf

The wlcore state was checked without the mutex being taken. This leads
to WARN_ONs sometimes if a notification arrives when the driver
is on, but the mutex is only taken after it is off. This usually
happens if stopping the driver while connected to a network.

Subject: [PATCH 0642/1722] wlcore: consider dummy packets when tx queues are
 empty

Don't ignore dummy packets when our queues are empty. This causes dummy
packets never to be sent when traffic is not suspended by FW thresholds,
which happens only in high Tx throughput situations. This may hurt Rx
performance.

Subject: [PATCH 0644/1722] wlcore: move handling from hardirq to the irq
 thread function

Spin locks and completions are expensive in hard IRQ context and cause
problems with RT kernels.  In RT kernels, both spin locks and
completions can schedule(), so we can't use them in hard irq context.

Move handling code into the irq thread function to avoid that.

Subject: [PATCH 0647/1722] mac80211: allow drivers to set default uAPSD
 parameters

mac80211 currently sets uAPSD parameters to have VO AC trigger-
and delivery-enabled, with maximum service period length.

Allow drivers to change these default settings since different
uAPSD client implementations may handle errors differently and
be able to recover from some errors.

Note: some APs may not function correctly if one or all ACs are
trigger- and delivery-enabled, see
http://thread.gmane.org/gmane.linux.kernel.wireless.general/93577.
We retested with this AP and later firmware doesn't have this
bug any more.

This variable is supposed to hold reference to the last extra_info in the

extra info is missing, so this variable is never used and causes confusion.

Remove it at the moment. We can add it back when necessary.

This function is in fact counting the ring slots required for responses.
Separate the concepts of ring slots and skb frags make the code clearer, as
now netfront and netback can have different MAX_SKB_FRAGS, slot and frag are
not mapped 1:1 any more.

Subject: [PATCH 0654/1722] dsa: fix freeing of sparse port allocation

If we have defined a sparse port allocation which is non-contiguous and
contains gaps, the code freeing port_names will just stop when it
encouters a first NULL port_names, which is not right, we should iterate
over all possible number of ports (DSA_MAX_PORTS) until we are done.

ip-header id needs to be incremented even if IP_DF flag is set.
This behaviour was changed in commit 490ab08127cebc25e3a26
(IP_GRE: Fix IP-Identification).

Following patch fixes it so that identification is always
incremented.

From 872de8ff04922e4ad95c5af39131ae9fbefe6ac5 Mon Sep 17 00:00:00 2001
From: Jussi Kivilinna <jussi.kivilinna@iki.fi>
Date: Sun, 17 Mar 2013 11:59:13 +0200
Subject: [PATCH 0660/1722] rtlwifi: usb: use usb_alloc_coherent for RX buffers

Use dedicated DMA coherent buffers for RX urbs, to avoid allocation of large
skbuffs in hard-irq context and improve performance.

Subject: [PATCH 0664/1722] mwifiex: add support to configure VHT for AP mode

Currently, default VHT configuration from the firmware is used
for the VHT operations. Adding vhtcfg command to configure the
firmware based on input received from cfg.

Enable VHT for AP mode only when cfg80211_ap_settings has a
VHT IE i.e., when ieee80211ac is set to 1 in the hostapd.conf.

Subject: [PATCH 0675/1722] GRE: Refactor GRE tunneling code.

Following patch refactors GRE code into ip tunneling code and GRE
specific code. Common tunneling code is moved to ip_tunnel module.
ip_tunnel module is written as generic library which can be used
by different tunneling implementations.

ip_tunnel module contains following components:
 - packet xmit and rcv generic code. xmit flow looks like
   (gre_xmit/ipip_xmit)->ip_tunnel_xmit->ip_local_out.
 - hash table of all devices.
 - lookup for tunnel devices.
 - control plane operations like device create, destroy, ioctl, netlink
   operations code.
 - registration for tunneling modules, like gre, ipip etc.
 - define single pcpu_tstats dev->tstats.
 - struct tnl_ptk_info added to pass parsed tunnel packet parameters.

ipip.h header is renamed to ip_tunnel.h

Subject: [PATCH 0677/1722] VXLAN: Fix vxlan stats handling.

Fixes bug in VXLAN code where is iptunnel_xmit() called with NULL
dev->tstats.
This bug was introduced in commit 6aed0c8bf7d2f389b (tunnel: use
iptunnel_xmit() again).

Following patch fixes bug by setting dev->tstats. It uses ip_tunnel
module code to share stats function.

Subject: [PATCH 0680/1722] net/davinci_emac: use devres APIs

Use devres APIs where possible to simplify error handling
in driver probe.

While at it, also rename the goto targets in error path to
introduce some consistency in how they are named.

 registering net_device.

Allocate FIFO address before registering net_device.
This is preparation to change the pseudo hardware address format
for firewire devices to include the offset of the FIFO for receipt
of unicast datagrams, instead of mangling ARP/NDP messages in the
driver layer.

Subject: [PATCH 0684/1722] firewire net: Ignore spd and max_payload advertised
 by ARP.

Stefan Richter <stefanr@s5r6.in-berlin.de> says:
| As far as I can tell, it would be best to ignore max_rec and sspd from ARP
| and NDP but keep using the respective information from firewire-core
| instead (handed over by fwnet_probe()).
|
| Why?  As I noted earlier, RFC 2734:1999 and RFC 3146:2001 were apparently
| written with a too simplistic notion of IEEE 1394 bus topology, resulting
| in max_rec and sspd in ARP-1394 and NDP-1394 to be useless, IMO.
|
| Consider a bus like this:
|
|     A ---- B ==== C
|
| A, B, C are all IP-over-1394 capable nodes.  ---- is an S400 cable hop,
| and ==== is an S800 cable hop.
|
| In case of unicasts or multicasts in which node A is involved as
| transmitter or receiver, as well as in case of broadcasts, the speeds
| S100, S200, S400 work and speed S400 is optimal.
|
| In case of anything else, IOW in case of unicasts or multicasts in which
| only nodes B and C are involved, the speeds S100, S200, S400, S800 work
| and speed S800 is optimal.
|
| Clearly, node A should indicate sspd = S400 in its ARP or NDP packets.
| But which sspd should nodes B and C set there?  Maybe they set S400, which
| would work but would waste half of the available bandwidth in the second
| case.  Or maybe they set S800, which is OK in the second case but would
| prohibit any communication with node A if blindly taken for correct.
|
| On the other hand, firewire-core *always* gives us the correct and optimum
| peer-to-peer speed and asynchronous packet payload, no matter how simple
| or complex the bus topology is and no matter in which temporal order nodes
| join the bus and are discovered.

Subject: [PATCH 0685/1722] firewire net, ipv4 arp: Extend hardware address and
 remove driver-level packet inspection.

Inspection of upper layer protocol is considered harmful, especially
if it is about ARP or other stateful upper layer protocol; driver
cannot (and should not) have full state of them.

IPv4 over Firewire module used to inspect ARP (both in sending path
and in receiving path), and record peer's GUID, max packet size, max
speed and fifo address.  This patch removes such inspection by extending
our "hardware address" definition to include other information as well:
max packet size, max speed and fifo.  By doing this, The neighbour
module in networking subsystem can cache them.

Note: As we have started ignoring sspd and max_rec in ARP/NDP, those
      information will not be used in the driver when sending.

When a packet is being sent, the IP layer fills our pseudo header with
the extended "hardware address", including GUID and fifo.  The driver
can look-up node-id (the real but rather volatile low-level address)
by GUID, and then the module can send the packet to the wire using
parameters provided in the extendedn hardware address.

This approach is realistic because IP over IEEE1394 (RFC2734) and IPv6
over IEEE1394 (RFC3146) share same "hardware address" format
in their address resolution protocols.

Here, extended "hardware address" is defined as follows:

union fwnet_hwaddr {
	u8 u[16];
	struct {
		__be64 uniq_id;		/* EUI-64			*/
		u8 max_rec;		/* max packet size		*/
		u8 sspd;		/* max speed			*/
		__be16 fifo_hi;		/* hi 16bits of FIFO addr	*/
		__be32 fifo_lo;		/* lo 32bits of FIFO addr	*/
	} __packed uc;
};

Note that Hardware address is declared as union, so that we can map full
IP address into this, when implementing MCAP (Multicast Cannel Allocation
Protocol) for IPv6, but IP and ARP subsystem do not need to know this
format in detail.

One difference between original ARP (RFC826) and 1394 ARP (RFC2734)
is that 1394 ARP Request/Reply do not contain the target hardware address
field (aka ar$tha).  This difference is handled in the ARP subsystem.

Subject: [PATCH 0687/1722] netlink: have length check of rtnl msg before deref

When the legacy array rtm_min still exists, the length check within
these functions is covered by rtm_min[RTM_NEWTFILTER],
rtm_min[RTM_NEWQDISC] and rtm_min[RTM_NEWTCLASS].

But after Thomas Graf removed rtm_min several days ago, these checks
are missing. Other doit functions should be OK.

Subject: [PATCH 0690/1722] 6lowpan: always enable link-layer acknowledgments

This feature is especially important when using fragmentation, because
the reassembly mechanism cannot recover from the loss of a fragment.

Note that some hardware ignore this flag and not will not transmit
acknowledgments even if this is set.

Subject: [PATCH 0693/1722] 6lowpan: fix first fragment (FRAG1) handling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The first fragment, FRAG1, must contain some payload according to the
specs. However, as it is currently written, the first fragment will
remain empty and only contain the 6lowpan headers.

This patch also extracts the transport layer information from the first
fragment. This information is used later on when uncompressing UDP
header.

Thanks to Wolf-Bastian Pöttner for noticing that the offset value was
not properly initialized.

NLMSG_HDRLEN is already aligned value. It's for directly reference

Subject: [PATCH 0701/1722] macvtap: set transport header before passing skb to
 lower device

Set the transport header for 1) some drivers (e.g ixgbe) needs l4 header 2)
precise packet length estimation (introduced in 1def9238) needs l4 header to
compute header length.

For the packets with partial checksum, the patch just set the transport header
to csum_start. Otherwise tries to use skb_flow_dissect() to get l4 offset, if it
fails, just pretend no l4 header.

 length for untrusted packets

gso_segs were reset to zero when kernel receive packets from untrusted

wrong. So this patch tries to estimate the correct gso_segs value before using
it in qdisc_pkt_len_init().

Subject: [PATCH 0708/1722] net: wireless: iwlegacy: add CONFIG_PM_SLEEP to
 suspend/resume functions

Add CONFIG_PM_SLEEP to suspend/resume functions to fix the following
build warning when CONFIG_PM_SLEEP is not selected. This is because
sleep PM callbacks defined by SIMPLE_DEV_PM_OPS are only used when
the CONFIG_PM_SLEEP is enabled.

drivers/net/wireless/iwlegacy/common.c:4894:1: warning: 'il_pci_suspend' defined but not used [-Wunused-function]

bond_resend_igmp_join_requests_delayed() calls _resend_igmp_join_requests()
under rcu_read_lock(), while it gets its own rcu_read_lock() for the whole
function. Remove the lock from the _delayed function.

Subject: [PATCH 0712/1722] stmmac: reorganize chain/ring modes removing
 Koptions

Previously we had two Koptions to decide if the stmmac
had to use either a ring or a chain to manage its descriptors.
This patch removes the Kernel configuration options and it allow us
to use the chain mode by passing a module option.
Ring mode continues to be the default.

Also with this patch, it will be easier to validate the driver built and
guarantee that all the two modes always compile fine.

From c24602ef86649376e9d71ea808cd877e414d340b Mon Sep 17 00:00:00 2001
From: Giuseppe CAVALLARO <peppe.cavallaro@st.com>
Date: Tue, 26 Mar 2013 04:43:06 +0000
Subject: [PATCH 0713/1722] stmmac: support extend descriptors

This patch is to support the extend descriptors available
in the chips newer than the 3.50.

In case of the extend descriptors cannot be supported,
at runtime, the driver will continue to work using the old style.

In detail, this support extends the main descriptor structure
adding new descriptors: 4, 5, 6, 7. The desc4 gives us extra
information about the received ethernet payload when it is
carrying PTP packets or TCP/UDP/ICMP over IP packets.
The descriptors 6 and 7 are used for saving HW L/H timestamps (PTP).

V2: this new version removes the Koption added in the first implementation
because all the checks now to verify if the extended descriptors are
actually supported happen at probe time.

Subject: [PATCH 0714/1722] stmmac: start adding pcs and rgmii core irq

This patch starts adding in the main ISR the management of the PCS and
RGMII/SGMII core interrupts. This is to help further development
on this area. Currently the core irq handler only clears the
PCS and S-R_MII interrupts and reports the event in the ethtool stats.

Subject: [PATCH 0715/1722] stmmac: initial support to manage pcs modes

This patch adds the minimal support to manage the PCS
modes (RGMII/SGMII) and restart the ANE.
Both TBI and RTBI are not yet supported.

Thanks to Byungho that wrote some part of this code
and tested SGMII too.

The only thing to be fixed is the get/set pause in
ethtool.

Subject: [PATCH 0716/1722] stmmac: add tx_skbuff_dma to save descriptors used
 by PTP

This patch adds a new pointer variable called "tx_skbuff_dma" to private
data structure. This variable will holds the physical address of packet
to be transmitted & same will be used to free/unmap the memory once the
corresponding packet is transmitted by device.

Prior to this patch the descriptor buffer pointer(ie des2) itself was
being used for freeing/unmapping the buffer memory. But in case PTP v1
with normal descriptor the field(des2) will be overwritten by device
with timestamp value, hence driver will loose the buffer pointer to be
freed/unmapped.

From 891434b18ec0a21cfa4788695165b74e8d4c0474 Mon Sep 17 00:00:00 2001
From: Rayagond Kokatanur <rayagond@vayavyalabs.com>
Date: Tue, 26 Mar 2013 04:43:10 +0000
Subject: [PATCH 0717/1722] stmmac: add IEEE PTPv1 and PTPv2 support.

This patch enhances the stmmac driver to support IEEE 1588-2002
PTP (Precision Time Protocol) version 1 and IEEE 1588-2008 PPT
version 2.

Precision Time Protocol(PTP),which enables precise synchronization
of clocks in measurement and control systems implemented with
technologies such as network communication,local computing,
& distributed objects.

Both PTPv1 and PTPv2 is selected at run-time using the HW capability
register.

The PTPv1 TimeStamp support can be used on chips that have the normal
descriptor structures and PTPv2 TimeStamp support can be used on chips
that have the Extended descriptors(DES4-5-6-7). All such sanity checks
are done and verified by using HW capability register.

V2: in this version the ethtool support has been included in this patch;
Koptions have been completely removed (previously added to select
PTP and PTPv2). PTPv1 and PTPv2 is now added in a single patch instead of
two patches.
get_timestamp() and get_systemtime() L/H have been combined into single APIs.

+7) Extended descriptors
+The extended descriptors give us information about the receive Ethernet payload
+when it is carrying PTP packets or TCP/UDP/ICMP over IP.
+These are not available on GMAC Synopsys chips older than the 3.50.

+Timestamps, new GMAC cores support the advanced timestamp features.
+IEEE 1588-2008 that can be enabled when configure the Kernel.
+
+9) SGMII/RGMII supports
+New GMAC devices provide own way to manage RGMII/SGMII.
+This information is available at run-time by looking at the
+HW capability register. This means that the stmmac can manage
+auto-negotiation and link status w/o using the PHYLIB stuff
+In fact, the HW provides a subset of extended registers to
+restart the ANE, verify Full/Half duplex mode and Speed.
+Also thanks to these registers it is possible to look at the
+Auto-negotiated Link Parter Ability.
+
+10) TODO:
  o XGMAC is not supported.
- o Add the PTP - precision time protocol
+ o Complete the TBI & RTBI support.
+ o extened VLAN support for 3.70a SYNP GMAC.

 coding
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a htonl() in network_coding.c when reading the sequence number
from received ogm_packet, to avoid wrong byte ordering when comparing
with a host value. This bug was introduced in
3ed7ada3f0bbcd058567bc0a8f9729a73eba7db6 ("batman-adv: network coding -
detect coding nodes and remove these after timeout").

Change the type of coded_packet->coded_len from uint16 to __be16 to
avoid wrong assumptions about endianness in later uses. Introduced in
c3289f3650d34b60296000a629c99f2488f7c3dd ("batman-adv: network coding -
code and transmit packets if possible").

Subject: [PATCH 0731/1722] batman-adv: Don't always delete softif when last
 slave was removed

batman-adv has an unusual way to manage softinterfaces. These will be created
automatically when a user writes to the batman-adv/mesh_iface file in sysfs and
removed when no slave device exists anymore.

This behaviour cannot be changed without breaking compatibility with existing
code. Instead other interfaces should be able to slightly reduce this behaviour
and provide a more common reaction to a removal of a slave interface.

Subject: [PATCH 0733/1722] batman-adv: Allow to use rntl_link for device
 creation/deletion

The sysfs configuration interface of batman-adv to add/remove soft-interfaces
is not deadlock free and doesn't follow the currently common way to create new
virtual interfaces.

An additional interface though rtnl_link is introduced which provides easy device
creation/deletion with tools like "ip":

$ ip link add dev bat0 type batadv
$ ip link del dev bat0

Subject: [PATCH 0734/1722] batman-adv: Allow to modify slaves of
 soft-interfaces through rntl_link

The sysfs configuration interface of batman-adv to add/remove slaves of an
soft-iface is not deadlock free and doesn't follow the currently common way to
modify slaves of an interface.

An additional configuration interface though rtnl_link is introduced which
provides easy device adding/removing with tools like "ip":
$ ip link set dev eth0 master bat0
$ ip link set dev eth0 nomaster

Subject: [PATCH 0735/1722] batman-adv: free an hard-interface before adding it

When adding a new hard interface (e.g. wlan0) to a soft interface (e.g. bat0)
and the former is already enslaved in another virtual interface (e.g. a software
bridge) batman-adv has to free it first and then continue with the adding
mechanism.

In this way the behaviour becomes consistent with what "ip link set master"
does. At the moment batman-adv enslaves the hard interface without checking for
the master device, possibly causing strange behaviours which are never wanted by
the users.

SAMA5D3 devices also embed CAN feature. Moreover if we want to produce a single
kernel image it is not useful to be too restrictive.

Subject: [PATCH 0741/1722] can: mcp251x: Remove redundant spi driver bus
 initialization

In ancient times it was necessary to manually initialize the bus field of an
spi_driver to spi_bus_type. These days this is done in spi_driver_register() so
we can drop the manual assignment.

The patch was generated using the following coccinelle semantic patch:
// <smpl>

identifier _driver;

struct spi_driver _driver = {
	.driver = {
-		.bus = &spi_bus_type,

Sometimes, we need probe and set the transport header for packets (e.g from

skb_probe_transport_header() which tries to probe and set the l4 header through
skb_flow_dissect(), if not just set the transport header to the hint passed by
caller.

Subject: [PATCH 0752/1722] bnx2x: Fix VF outer vlan removal

Outer vlan removal in VF queues was made according to the VF's
multi-function mode (which is never set).
Instead, the PF's multi-function mode should be used to determine
if outer vlan removal is needed.

Subject: [PATCH 0753/1722] bnx2x: Prevent VF race

The mail box containing the Vf-Pf messages is susceptible
to a race - it's possible for 2 flows to try and write commands,
causing one to override the other's message.
Use a mutex to synchronize the access, preventing said race.

Subject: [PATCH 0758/1722] net: frag, avoid several CPUs grabbing same frag
 queue during LRU evictor loop

The LRU list is protected by its own lock, since commit 3ef0eb0db4
(net: frag, move LRU list maintenance outside of rwlock), and
no-longer by a read_lock.

This makes it possible, to remove the inet_frag_queue, which is about
to be "evicted", from the LRU list head.  This avoids the problem, of
several CPUs grabbing the same frag queue.

Note, cannot remove the inet_frag_lru_del() call in fq_unlink()
called by inet_frag_kill(), because inet_frag_kill() is also used in
other situations.  Thus, we use list_del_init() to allow this
double list_del to work.

In case of fixed speed set up for a NIC (e.g. ethtool -s eth0 autoneg off speed
100 duplex full) with an ethernet cable plugged off, the mentioned algorithm
slows down a NIC speed, so further cable hook-up leads to nonoperable link state.

 card

FW can be woken up even by accessing device registers; we need
not explicitily enable interrupts for doing this. Future PCIe
devices will not be woken up by writing to host registers.
This patch enables driver to wake up device by reading FW status
register.

Also devices with sleep cookie enabled need some more time before
proceeding with processing. Handle this by adding a delay loop.

Subject: [PATCH 0769/1722] brcmsmac: remove brcms_bss_cfg->BSS

This was a read only member. The checks using BSS are replaced by
better fitting checks of the new type member.

The change in brcms_c_tbtt() was based on code from b43, in
brcms_c_ps_allowed() the same happens with BSS being true or false,
beaconing and probe responses are just needed in ap mode.

Subject: [PATCH 0776/1722] brcmsmac: add beacon template support

This makes it possible that a beacon template provided by mac80211 is
written to the hardware for constant beaconing.

This is based on an old version of brcmsmac, on b43 and the spec b43 is
based on.

Subject: [PATCH 0778/1722] brcmsmac: add support for probe response template

The ucode is able to answer probe response by itself. This writes such
a template into the specific memory. Currently the probe requests are
also send to mac80211 so there are more answers send to a requesting
client. We have to make the ucode stop sending probe requests to the
driver.

Subject: [PATCH 0779/1722] brcmsmac: deactivate ucode sending probe responses

It is possible to configure the ucode to automatically send the probe
responses to the clients after they send a probe request. At least for
WPS the userspace needs to answer the probe requests and we do not know
a way to say to the ucode to just handle the normal probe requests, so
for now no probe requests should be handled by the ucode.

Subject: [PATCH 0782/1722] mwl8k: always apply configuration even when device
 is idle

Fix settings not being applied when the device is idle and the firmware
gets reloaded (because of changing from STA to AP mode). This caused
the device using the wrong channel (and likely band), e.g. a 5 GHz only
card still defaulted to channel 6 in the 2.4 GHz band when left
unconfigured.

This issue was always present, but only made visible with "mwl8k: Do not
call mwl8k_cmd_set_rf_channel unconditionally" (0f4316b9), since before
that the channel was (re-)configured at the next _config call even when
it did not change from the mac80211 perspective.

Subject: [PATCH 0783/1722] carl9170: remove fast channel change feature

Marco Fonseca reported a issue with his carl9170 device:
"I'm seeing a problem with the carl driver. If I change channels
repeatedly on the 2.4ghz band, monitoring (e.g. tcpdump) will
eventually halt.  I've seen this on various versions of the carl
driver/firmware (both from 1.9.4 to 1.9.7)"
<http://marc.info/?l=linux-wireless&m=136381302428113>

The culprit was identified as "fast channel change feature" which
according to Adrian Chadd is: "... notoriously unreliable and
really only fully debugged on some very later chips."
<http://marc.info/?l=linux-wireless&m=136416984531380>

Therefore, this patch removes the fast channel change feature.
The phy will now always have to go through a cold reset when
changing channels, but it should no longer become deaf.

Date: Wed, 27 Mar 2013 17:26:05 +0100
Subject: [PATCH 0790/1722] brcmsmac: remove some pmu functions and use the
 bcma equivalents

This removes the following functions:
si_pmu_chipcontrol() => bcma_chipco_chipctl_maskset()
si_pmu_regcontrol() => bcma_chipco_regctl_maskset()
si_pmu_pllcontrol() => bcma_chipco_pll_maskset()
si_pmu_pllupd() => bcma_cc_set32()
si_pmu_alp_clock() => bcma_chipco_get_alp_clock()

This also removed the sih member from struct shared_phy.

Subject: [PATCH 0791/1722] yam: remove redundant null check on dev

yam_open has a redundant null check on null,  it will
never be called with dev == NULL. Remove this redundant check.
This also cleans up a smatch warning:

drivers/net/hamradio/yam.c:869 yam_open() warn: variable

Subject: [PATCH 0792/1722] net: fix compile error of implicit declaration of
 skb_probe_transport_header
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The commit 40893fd(net: switch to use skb_probe_transport_header())
involes a new error accidently. When NET_SKBUFF_DATA_USES_OFFSE is
not enabled, below compile error happens:

  CC      net/packet/af_packet.o
  net/packet/af_packet.c: In function ‘packet_sendmsg_spkt’:
  net/packet/af_packet.c:1516:2: error: implicit declaration of function ‘skb_probe_transport_header’ [-Werror=implicit-function-declaration]
  cc1: some warnings being treated as errors
  make[2]: *** [net/packet/af_packet.o] Error 1
  make[1]: *** [net/packet] Error 2
  make: *** [net] Error 2

As it seems skb_probe_transport_header() is not related to
NET_SKBUFF_DATA_USES_OFFSE, we should move the definition of
skb_probe_transport_header() out of scope of
NET_SKBUFF_DATA_USES_OFFSE macro.

Subject: [PATCH 0795/1722] net: add ETH_P_802_3_MIN

Add a new constant ETH_P_802_3_MIN, the minimum ethernet type for
an 802.3 frame. Frames with a lower value in the ethernet type field
are Ethernet II.

Also update all the users of this value that David Miller and
I could find to use the new constant.

Also correct a bug in util.c. The comparison with ETH_P_802_3_MIN
should be >= not >.

As suggested by Jesse Gross.

Compile tested only.

Subject: [PATCH 0796/1722] e1000e: additional error handling on PHY register
 accesses

PHY reads/writes via the MDIC register could potentially return results
from a previous PHY register access.  If that happens, the offset in the
returned results will be that of the previous access and if that is
different from the expected offset, log a debug message and error out.

Subject: [PATCH 0797/1722] e1000e: slow performance between two 82579
 connected via 10Mbit hub

Two 82579 LOMs connected via a 10Mb hub experience extraordinarily low
performance.  This is because 82579 is excessively aggressive on transmit
at 10Mb half-duplex and will not provide sufficient time for the link
partner to transmit.  When the link partner is also 82579, the result is a
lot of collisions (and corresponding re-transmits) that cause the poor
performance. To work-around this issue, significantly increase the IPG in
the MAC to allow enough gap for the link partner to transmit and reduce the
Rx latency in the analog PHY to 0 to reduce the number of collisions.

When the MAC and PHY are in two different modes (different power levels
and interconnect speeds), it could take a long time before a PHY register
access timed out using the existing MAC-PHY interconnect configuration
coded into the driver for ICH- and PCH-based LOMs.  Introduce an I217/I218-
specific .setup_physical_interface operation which does not override the
interconnect configuration in the NVM.

 set/disabled as required

Devices supported by the driver which support EEE (currently 82579, I217
and I218) are advertising EEE capabilities during auto-negotiation even
when EEE has been disabled.  In addition to not acting as expected, this
also caused the EEE status reported by 'ethtool --show-eee' to be wrong
when two of these devices are connected back-to-back and EEE is disabled
on one.  In addition to fixing this issue, the ability for the user to
specify which speeds (100 or 1000 full-duplex) to advertise EEE support
has been added.

Subject: [PATCH 0801/1722] e1000e: enable EEE by default

Now that IEEE802.3az-2010 Energy Efficient Ethernet has been approved as
standard (September 2010) and the driver can enable and disable it via
ethtool, enable the feature by default on parts which support it.

Subject: [PATCH 0802/1722] e1000e: add support for LTR on I217/I218

Set the Latency Tolerance Reporting (LTR) values for the "PCIe-like"
GbE MAC in the Lynx Point PCH based on Rx buffer size and link speed
when link is up (which must not exceed the maximum latency supported
by the platform), otherwise specify there is no LTR requirement.
Unlike true-PCIe devices which set the LTR maximum snoop/no-snoop
latencies in the LTR Extended Capability Structure in the PCIe Extended
Capability register set, on this device LTR is set by writing the
equivalent snoop/no-snoop latencies in the LTRV register in the MAC and
set the SEND bit to send an Intel On-chip System Fabric sideband (IOSF-SB)
message to the PMC.

Subject: [PATCH 0805/1722] e1000e: fix scheduling while atomic bugs

The previous commit ce43a2168c59bc47b5f0c1825fd5f9a2a9e3b447 (e1000e:
cleanup USLEEP_RANGE checkpatch checks) converted a number of delays and
sleeps as recommended in ./Documentation/timers/timers-howto.txt.
Unfortunately, a few of the udelay() to usleep_range() conversions are in
code paths that are in an atomic context in which usleep_range() should
not be used.  Revert those specific changes.

Subject: [PATCH 0806/1722] ixgbe: Don't give VFs random MAC addresses

If the user has not assigned a MAC address to a VM, then don't give it a
random one. Instead, just give it zeros and let it figure out what to do
with them.

Subject: [PATCH 0807/1722] ixgbevf: Adjust to handle unassigned MAC address
 from PF

If the administrator has not assigned a MAC address to the VF via the
PF then handle it gracefully by generating a temporary MAC address.
This ensures that we always know when we have a random address and
udev won't get upset about it.

At least in the cadence IP core on the Xilinx Zynq SoC the TCOMP/RCOMP flags
are not auto-cleaned. As these flags are evaluated, they need to be cleaned.

Subject: [PATCH 0815/1722] net/macb: force endian_swp_pkt_en to off

The core has a bit for swapping packet data endianism.
Reset default from Cadence is off. Xilinx however, who uses this core on the
Zynq SoCs, opted for on.
Force it to off. This shouldn't change the behaviour for current users of the
macb, but enables usage on Zynq devices.

Commit 941912133025926307c7a65b203fa38403b1063a replaced the macros
NLMSG_NEXT with calls to nlmsg_next which produces this warning:

kernel/audit.c: In function ‘audit_receive_skb’:
kernel/audit.c:928:3: warning: passing argument 2 of ‘nlmsg_next’ makes pointer from integer without a cast

                 from kernel/audit.c:55:

Fix this by sending the intended pointer.

In rtnl_fdb_dump() when the fdb_dump ndo op is not populated
we never set the idx value so that cb->arg[0] is always 0.
Resulting in a endless loop of messages.

Subject: [PATCH 0824/1722] sh_eth: add R-Car support for real

Commit d0418bb7123f44b23d69ac349eec7daf9103472f (net: sh_eth: Add eth support
for R8A7779 device) was a failed attempt to add support for one of members of
the R-Car SoC family.  That's for three reasons: it treated R8A7779 the  same
as SH7724 except including quite dirty hack adding ECMR_ELB  bit  to the mask
in sh_eth_set_rate() while not removing ECMR_RTM bit (despite it's reserved in
R-Car Ether), and it didn't add a new register offset array despite the closest
SH_ETH_REG_FAST_SH4 mapping differs by 0x200 to the offsets all the R-Car Ether
registers have, and also some of the registers in this old mapping don't exist
on R-Car Ether (due to this, SH7724's 'sh_eth_my_cpu_data' structure is not
adequeate for R-Car too).  Fix all these shortcomings, restoring the SH7724
related section to its pristine state...

Subject: [PATCH 0825/1722] cirrus: cs89x0: remove two obsolete Kconfig macros

The CONFIG_ARCH_IXDP2X01 and CONFIG_MACH_IXDP2351 Kconfig macros are
unused since the ixp23xx and ixp2000 platforms were removed in v3.5. So
remove the last code still depending on these macros. And since
CS89x0_NONISA_IRQ was only set if either of these two macros was defined
we can also remove that macro and the code depending on it.

Subject: [PATCH 0826/1722] qlcnic: Support SR-IOV enable and disable

o Add QLCNIC_SRIOV to Kconfig.
o Provide PCI sysfs hooks to enable and disable SR-IOV.
o Allow enabling only when CONFIG_QLCNIC_SRIOV is defined.
o qlcnic_sriov_pf.c has all the PF related SR-IOV
  functionality.
o qlcnic_sriov_common.c has VF functionality and SR-IOV
  functionality which is common between VF and PF.
o qlcnic_sriov.h is a common header file for SR-IOV defines.

Subject: [PATCH 0828/1722] qlcnic: Use shared interrupt vector for Tx and Rx

o VF will use shared MSI-X interrupt vector for Tx and Rx.
o When QLCNIC_INTR_SHARED flag is set Tx and Rx will
  share MSI-X interrupt vector. Tx will use a separate
  MSI-X interrupt vector from Rx otherwise.

Subject: [PATCH 0829/1722] qlcnic: VF-PF communication channel implementation

o Adapter provides communication channel between VF and PF.
  Any control commands from the VF driver are sent to the PF driver
  through this communication channel. PF driver validates the
  commands before sending them to the adapter. Similarly PF driver
  forwards any control command responses  to the VF driver
  through this communication channel.  Adapter sends message pending
  event to VF or PF when there is an outstanding response or a command
  for VF or PF respectively. When a command or a response is sent over
  a channel VF or PF cannot send another command or a response
  until adapter sends a channel free event. Adapter allocates 1K area to
  VF and  PF each for this communication.
o Commands and  responses are encapsulated in a header. Header determines
  sequence id, number of fragments, fragment number etc.

From 7cb03b2347d5edace4fb8e7dd9d6c3889368a179 Mon Sep 17 00:00:00 2001
From: Rajesh Borundia <rajesh.borundia@qlogic.com>
Date: Fri, 29 Mar 2013 05:46:37 +0000
Subject: [PATCH 0830/1722] qlcnic: Support VF-PF communication channel
 commands.

o Add support for commands from VF to PF.
o PF validates the commands sent by the VF before sending
  it to adapter.
o vPort is a container of resources. PF creates vPort
  for VFs and attach resources to it. vPort is
  transparent to the VF.
o Separate 83xx TX and RX hardware resource cleanup from 82xx.

Subject: [PATCH 0834/1722] openvswitch: Use nla_memcpy() to memcpy() data from
 attributes

Less error prone as it takes into account the length of both the
destination buffer and the source attribute and documents when
data is copied from an attribute.

Subject: [PATCH 0835/1722] openvswitch: Refine Netlink message size
 calculation and kill FLOW_BUFSIZE

Kills the FLOW_BUFSIZE constant which needs to be calculated manually
and replaces it with key_attr_size() based on nla_total_size().
Calculates the size of datapath messages instead of relying on
NLMSG_DEFAULT_SIZE and moves the existing message size calculations
into own functions for clarity.

Subject: [PATCH 0840/1722] ip_gre: don't overwrite iflink during net_dev init

iflink is currently set to 0 in __gre_tunnel_init(). This
function is invoked in gre_tap_init() and
ipgre_tunnel_init() which are both used to initialise the
ndo_init field of the respective net_device_ops structs
(ipgre.. and gre_tap..) used by GRE interfaces.

However, in netdevice_register() iflink is first set to -1,
then ndo_init is invoked and then iflink is assigned to a
proper value if and only if it still was -1.

Assigning 0 to iflink in ndo_init is therefore first
preventing netdev_register() to correctly assign it a proper
value and then breaking iflink at all since 0 has not
correct meaning.

Fix this by removing the iflink assignment in
__gre_tunnel_init().

Introduced by c54419321455631079c7d6e60bc732dd0c5914c5

Subject: [PATCH 0842/1722] net: reorder some fields of net_device

As time passed, some fields were added in net_device, and not
at sensible offsets.

Lets reorder some fields to reduce number of cache lines in RX path.
Fields not used in data path should be moved out of this critical cache
line.

In particular, move broadcast[] to the end of the rx section,
as it is less used, and ethernet uses only the beginning of the 32bytes
field.

Before patch :

offsetof(struct net_device,dev_addr)=0x258
offsetof(struct net_device,rx_handler)=0x2b8
offsetof(struct net_device,ingress_queue)=0x2c8
offsetof(struct net_device,broadcast)=0x278

After :

offsetof(struct net_device,dev_addr)=0x280
offsetof(struct net_device,rx_handler)=0x298
offsetof(struct net_device,ingress_queue)=0x2a8
offsetof(struct net_device,broadcast)=0x2b0

Subject: [PATCH 0843/1722] macvlan: use the right RCU api

Make sure we use proper API to fetch dev->rx_handler_data,
instead of ugly casts.

Rename macvlan_port_get() to macvlan_port_get_rtnl() to document fact
that we hold RTNL when needed, with lockdep support.

This removes sparse warnings as well (CONFIG_SPARSE_RCU_POINTER=y)

Subject: [PATCH 0844/1722] doc: packet: add minimal TPACKET_V3 example code

Lost in space for a long time, but it finally came back to us from
some ancient code tombs. This patch adds a minimal runnable example
of Linux' packet mmap(2) from Chetan Loke's TPACKET_V3. Special
thanks to David S. Miller, and also Eric Leblond and Victor Julien!

++ AF_PACKET TPACKET_V3 example
+-------------------------------------------------------------------------------
+
+AF_PACKET's TPACKET_V3 ring buffer can be configured to use non-static frame
+sizes by doing it's own memory management. It is based on blocks where polling
+works on a per block basis instead of per ring as in TPACKET_V2 and predecessor.
+
+It is said that TPACKET_V3 brings the following benefits:
+ *) ~15 - 20% reduction in CPU-usage
+ *) ~20% increase in packet capture rate
+ *) ~2x increase in packet density
+ *) Port aggregation analysis
+ *) Non static frame size to capture entire packet payload
+
+So it seems to be a good candidate to be used with packet fanout.
+
+Minimal example code by Daniel Borkmann based on Chetan Loke's lolpcap (compile
+it with gcc -Wall -O2 blob.c, and try things like "./a.out eth0", etc.):

Subject: [PATCH 0845/1722] net: add option to enable error queue packets
 waking select

Currently, when a socket receives something on the error queue it only wakes up
the socket on select if it is in the "read" list, that is the socket has
something to read. It is useful also to wake the socket if it is in the error
list, which would enable software to wait on error queue packets without waking
up for regular data on the socket. The main use case is for receiving
timestamped transmit packets which return the timestamp to the socket via the
error queue. This enables an application to select on the socket for the error
queue only instead of for the regular traffic.

-v2-
* Added the SO_SELECT_ERR_QUEUE socket option to every architechture specific file
* Modified every socket poll function that checks error queue

Subject: [PATCH 0846/1722] mwifiex: change default tx/rx win_size for BA setup

This patch fixes an issue where RX throughput values observed
were substantially lower than TX counterparts for PCIe8897 STA.
PCIe8897 supports larger rx_win_size. After changing these values
we see big improvement for TX and RX throughput values.

Different tx_win_size and rx_win_size are used for AP mode.

All BA setup related initialization has been moved to separate
function.

Subject: [PATCH 0847/1722] mwifiex: use separate AMPDU tx/rx window sizes in
 11ac networks

Newer 11ac enabled chipsets have more TX and RX buffers in FW
and hardware; so they may support larger TX and RX window sizes
for BA. Reset BA settings during association, adhoc join/start
or start_ap() if we are joining/creating 11ac network.

Subject: [PATCH 0852/1722] rt2x00: rt2800lib: probe RT chipset earlier

The 'rt2800_validate_eeprom' function uses the type of
the RT chipset for verifying the number of RX streams
on RT28x0 devices. However the type of the RT chipset
is not yet detected when the 'rt2800_validate_eeprom'
function is called.

Move the RT chipset detection code into a separate helper
function, and call it before rt2800_validate_eeprom.

Subject: [PATCH 0857/1722] rtlwifi: Rework rtl_lps_leave() and rtl_lps_enter()
 to use work queue

In commit a5ffbe0, some of the calls to rtl_lps_leave() were switched
to be called from a work queue to avoid a scheduling while atomic bug.
This patch converts the remaining calls to use the work queue. In
addition, the call to rtl_lps_enter() is also switched to the work
queue. None of these newly converted calls had triggered the bug (yet),
but this change make all of them fit a single pattern.

From e6deaf810cc4b6437d55179660776e131ac059df Mon Sep 17 00:00:00 2001
From: Larry Finger <Larry.Finger@lwfinger.net>
Date: Sun, 24 Mar 2013 22:06:55 -0500
Subject: [PATCH 0859/1722] rtlwifi: rtl8192c: rtl8192ce: rtl8192cu: rtl8192de:
 rtl8723ae: Add changes required by adding rtl81988ee

This patch combines the remaining changes in the rtlwifi family to handle
the addition of rtl8188ee. A number of these changes eliminate some CamelCase
variable names, and other shorten common variable names so that long lines
in the new driver could be shortened.

Subject: [PATCH 0862/1722] net: add skb_dst_set_noref_force

Rename skb_dst_set_noref to __skb_dst_set_noref and
add force flag as suggested by David Miller. The new wrapper
skb_dst_set_noref_force will force dst entries that are not
cached to be attached as skb dst without taking reference
as long as provided dst is reclaimed after RCU grace period.

Subject: [PATCH 0863/1722] ipvs: avoid routing by TOS for real server

Avoid replacing the cached route for real server
on every packet with different TOS. I doubt that routing
by TOS for real server is used at all, so we should be
better with such optimization.

The real server becomes unreachable on down event,
no need to wait device unregistration. Should help in
releasing dsts early before dst->dev is replaced with lo.

Subject: [PATCH 0867/1722] ipvs: no need to reroute anymore on DNAT over
 loopback

After commit 70e7341673 (ipv4: Show that ip_send_reply()
is purely unicast routine.) we do not need to reroute DNAT-ed
traffic over loopback because reply uses iph daddr and not
rt_spec_dst.

From 4115ded131645a7311a5d9afa9ff2b263dd91c2d Mon Sep 17 00:00:00 2001
From: Julian Anastasov <ja@ssi.bg>
Date: Thu, 21 Mar 2013 11:58:05 +0200
Subject: [PATCH 0869/1722] ipvs: consolidate all dst checks on transmit in one
 place

Consolidate the PMTU checks, ICMP sending and
skb_dst modification in __ip_vs_get_out_rt and
__ip_vs_get_out_rt_v6. Now skb_dst is changed early
to simplify the transmitters.

Make sure update_pmtu is called only for local clients.

From 026ace060dfe29275d2188297a62fa37d6c1a02c Mon Sep 17 00:00:00 2001
From: Julian Anastasov <ja@ssi.bg>

Subject: [PATCH 0870/1722] ipvs: optimize dst usage for real server

Currently when forwarding requests to real servers
we use dst_lock and atomic operations when cloning the
dst_cache value. As the dst_cache value does not change
most of the time it is better to use RCU and to lock
dst_lock only when we need to replace the obsoleted dst.
For this to work we keep dst_cache in new structure protected
by RCU. For packets to remote real servers we will use noref
version of dst_cache, it will be valid while we are in RCU
read-side critical section because now dst_release for replaced
dsts will be invoked after the grace period. Packets to
local real servers that are passed to local stack with
NF_ACCEPT need a dst clone.

Subject: [PATCH 0871/1722] ipvs: convert app locks

We use locks like tcp_app_lock, udp_app_lock,
sctp_app_lock to protect access to the protocol hash tables
from readers in packet context while the application
instances (inc) are [un]registered under global mutex.

As the hash tables are mostly read when conns are
created and bound to app, use RCU for readers and reclaim
app instance after grace period.

Simplify ip_vs_app_inc_get because we use usecnt
only for statistics and rely on module refcounting.

Subject: [PATCH 0872/1722] ipvs: remove rs_lock by using RCU

rs_lock was used to protect rs_table (hash table)
from updaters (under global mutex) and readers (packet handlers).
We can remove rs_lock by using RCU lock for readers. Reclaiming
dest only with kfree_rcu is enough because the readers access
only fields from the ip_vs_dest structure.

Use hlist for rs_table.

As we are now using hlist_del_rcu, introduce in_rs_table
flag as replacement for the list_empty checks which do not
work with RCU. It is needed because only NAT dests are in
the rs_table.

Subject: [PATCH 0873/1722] ipvs: convert locks used in persistence engines

Allow the readers to use RCU lock and for
PE module registrations use global mutex instead of
spinlock. All PE modules need to use synchronize_rcu
in their module exit handler.

From 088339a57d6042a8a19a3d5794594b558cd7b624 Mon Sep 17 00:00:00 2001
From: Julian Anastasov <ja@ssi.bg>

Subject: [PATCH 0874/1722] ipvs: convert connection locking

Convert __ip_vs_conntbl_lock_array as follows:

- readers that do not modify conn lists will use RCU lock
- updaters that modify lists will use spinlock_t

Now for conn lookups we will use RCU read-side
critical section. Without using __ip_vs_conn_get such
places have access to connection fields and can
dereference some pointers like pe and pe_data plus
the ability to update timer expiration. If full access
is required we contend for reference.

We add barrier in __ip_vs_conn_put, so that
other CPUs see the refcnt operation after other writes.

With the introduction of ip_vs_conn_unlink()
we try to reorganize ip_vs_conn_expire(), so that
unhashing of connections that should stay more time is
avoided, even if it is for very short time.

Subject: [PATCH 0875/1722] ipvs: reorder keys in connection structure

__ip_vs_conn_in_get and ip_vs_conn_out_get are
hot places. Optimize them, so that ports are matched first.
By moving net and fwmark below, on 32-bit arch we can fit
caddr in 32-byte cache line and all addresses in 64-byte
cache line.

Subject: [PATCH 0877/1722] ipvs: change ip_vs_sched_lock to mutex

The global list with schedulers ip_vs_schedulers
is accessed only from user context - configuration and
scheduler module [un]registration. Use ip_vs_sched_mutex
instead.

Date: Fri, 22 Mar 2013 11:46:37 +0200
Subject: [PATCH 0878/1722] ipvs: preparations for using rcu in schedulers

Allow schedulers to use rcu_dereference when
returning destination on lookup. The RCU read-side critical
section will allow ip_vs_bind_dest to get dest refcnt as
preparation for the step where destinations will be
deleted without an IP_VS_WAIT_WHILE guard that holds the
packet processing during update.

	Add new optional scheduler methods add_dest,
del_dest and upd_dest. For now the methods are called
together with update_service but update_service will be
removed in a following change.

some schedulers.

Subject: [PATCH 0881/1722] ipvs: convert lblc scheduler to rcu

The schedule method now needs _rcu list-traversal
primitive for svc->destinations. The read_lock for sched_lock is
removed. Use a dead flag to prevent new entries to be created
while scheduler is reclaimed. Use hlist for the hash table.

The schedule method now needs _rcu list-traversal

removed. The set.lock is removed because now it is used in
rare cases, mostly under sched_lock.

Subject: [PATCH 0889/1722] ipvs: convert wrr scheduler to rcu

The schedule method now needs _rcu list-traversal
primitive for svc->destinations. As the weight for some
dest can be reduced during dest selection, change the
algorithm to check weights by using minimum weights in the
1 .. max_weight-(di-1) range, with the same step (di). By this
way we ensure that there will be always a weight >= 1 check
before claiming that all destinations are overloaded.

Subject: [PATCH 0890/1722] ipvs: reorganize dest trash

All dests will go to trash, no exceptions.
But we have to use new list node t_list for this, due
to RCU changes in following patches. Dests will wait there
initial grace period and later all conns and schedulers to
put their reference. The dests don't get reference for
staying in dest trash as before.

	As result, we do not load ip_vs_dest_put with
extra checks for last refcnt and the schedulers do not
need to play games with atomic_inc_not_zero while
selecting best destination.

From 413c2d04e9494ca38629d8a7ffeff1e4398a9fe3 Mon Sep 17 00:00:00 2001
From: Julian Anastasov <ja@ssi.bg>
Date: Fri, 22 Mar 2013 11:46:52 +0200
Subject: [PATCH 0893/1722] ipvs: convert dests to rcu

In previous commits the schedulers started to access
svc->destinations with _rcu list traversal primitives
because the IP_VS_WAIT_WHILE macro still plays the role of
grace period. Now it is time to finish the updating part,
i.e. adding and deleting of dests with _rcu suffix before
removing the IP_VS_WAIT_WHILE in next commit.

We use the same rule for conns as for the
schedulers: dests can be searched in RCU read-side critical
section where ip_vs_dest_hold can be called by ip_vs_bind_dest.

Some things are not perfect, for example, calling
functions like ip_vs_lookup_dest from updating code under
RCU, just because we use some function both from reader
and from updater.

From ceec4c3816818459d90c92152e61371ff5b1d5a1 Mon Sep 17 00:00:00 2001
From: Julian Anastasov <ja@ssi.bg>
Date: Fri, 22 Mar 2013 11:46:53 +0200
Subject: [PATCH 0894/1722] ipvs: convert services to rcu

This is the final step in RCU conversion.

Things that are removed:

- svc->usecnt: now svc is accessed under RCU read lock
- svc->inc: and some unused code
- ip_vs_bind_pe and ip_vs_unbind_pe: no ability to replace PE
- __ip_vs_svc_lock: replaced with RCU
- IP_VS_WAIT_WHILE: now readers lookup svcs and dests under
	RCU and work in parallel with configuration

Other changes:

- before now, a RCU read-side critical section included the
calling of the schedule method, now it is extended to include
service lookup
- ip_vs_svc_table and ip_vs_svc_fwm_table are now using hlist
- svc->pe and svc->scheduler remain to the end (of grace period),
	the schedulers are prepared for such RCU readers
	even after done_service is called but they need
	to use synchronize_rcu because last ip_vs_scheduler_put
	can happen while RCU read-side critical sections
	use an outdated svc->scheduler pointer
- as planned, update_service is removed
- empty services can be freed immediately after grace period.
	If dests were present, the services are freed from
	the dest trash code

From ac69269a45e84c1772dcb9e77db976a932f4af22 Mon Sep 17 00:00:00 2001
From: Julian Anastasov <ja@ssi.bg>
Date: Fri, 22 Mar 2013 11:46:54 +0200
Subject: [PATCH 0895/1722] ipvs: do not disable bh for long time

We used a global BH disable in LOCAL_OUT hook.
Add _bh suffix to all places that need it and remove
the disabling from LOCAL_OUT and sync code.

Functions like ip_defrag need protection from
BH, so add it. As for nf_nat_mangle_tcp_packet, it needs
RCU lock.

Subject: [PATCH 0897/1722] netfilter: xt_NFQUEUE: introduce CPU fanout

Current NFQUEUE target uses a hash, computed over source and
destination address (and other parameters), for steering the packet
to the actual NFQUEUE. This, however forgets about the fact that the
packet eventually is handled by a particular CPU on user request.

If E. g.

  1) IRQ affinity is used to handle packets on a particular CPU already
     (both single-queue or multi-queue case)

and/or

  2) RPS is used to steer packets to a specific softirq

the target easily chooses an NFQUEUE which is not handled by a process
pinned to the same CPU.

The idea is therefore to use the CPU index for determining the
NFQUEUE handling the packet.

E. g. when having a system with 4 CPUs, 4 MQ queues and 4 NFQUEUEs it
looks like this:

 +-----+  +-----+  +-----+  +-----+
 |NFQ#0|  |NFQ#1|  |NFQ#2|  |NFQ#3|
 +-----+  +-----+  +-----+  +-----+
    ^        ^        ^        ^
    |        |NFQUEUE |        |
    +        +        +        +
 +-----+  +-----+  +-----+  +-----+
 |rx-0 |  |rx-1 |  |rx-2 |  |rx-3 |
 +-----+  +-----+  +-----+  +-----+

The NFQUEUEs not necessarily have to start with number 0, setups with
less NFQUEUEs than packet-handling CPUs are not a problem as well.

This patch extends the NFQUEUE target to accept a new
NFQ_FLAG_CPU_FANOUT flag. If this is specified the target uses the
CPU index for determining the NFQUEUE being used. I have to introduce
rev3 for this. The 'flags' are folded into _v2 'bypass'.

By changing the way which queue is assigned, I'm able to improve the
performance if the processes reading on the NFQUEUs are pinned
correctly.

Its pretty plainly the result of an skb fragment getting unmapped without having
its initial mapping operation checked for errors.  This patch corrects that.

Subject: [PATCH 0908/1722] ipconfig: add informative timeout messages while
 waiting for carrier

Commit 3fb72f1e6e6165c5f495e8dc11c5bbd14c73385c ("ipconfig wait
for carrier") added a "wait for carrier on at least one interface"
policy, with a worst case maximum wait of two minutes.

However, if you encounter this, you won't get any feedback from
the console as to the nature of what is going on.  You just see
the booting process hang for two minutes and then continue.

Here we add a message so the user knows what is going on, and
hence can take action to rectify the situation (e.g. fix network
cable or whatever.)  After the 1st 10s pause, output now begins
that looks like this:

	Waiting up to 110 more seconds for network.
	Waiting up to 100 more seconds for network.
	Waiting up to 90 more seconds for network.
	Waiting up to 80 more seconds for network.
	...

Since most systems will have no problem getting link/carrier in the
1st 10s, the only people who will see these messages are people with
genuine issues that need to be resolved.

Subject: [PATCH 0909/1722] of_net.h: Provide empty functions if OF_NET is not
 configured

of_get_mac_address() and of_get_phy_mode() are only provided if OF_NET
is configured. While most callers check for the define, not all do, and those
who do require #ifdef around the code. For those who don't, the missing check
can result in errors such as

arch/powerpc/sysdev/tsi108_dev.c:107:3: error: implicit declaration of
	function 'of_get_mac_address' [-Werror=implicit-function-declaration]
arch/powerpc/sysdev/mv64x60_dev.c:253:2: error: implicit declaration of
	function 'of_get_mac_address' [-Werror=implicit-function-declaration]

Provide empty functions if OF_NET is not configured.
This is safe because all callers do check the return values.

Since of_get_mac_address() is now defined even if CONFIG_OF_NET
is not configured, the ifdef around the code calling it is no longer
necessary and can be removed.

Similar, since of_get_phy_mode() is now defined as dummy function
if OF_NET is not configured, it is no longer necessary to provide
an OF dependent function as front-end. Also, the function depends
on OF_NET, not on OF, so the conditional code was not correct anyway.

Subject: [PATCH 0913/1722] net/nxp/lpc_eth: Drop ifdef CONFIG_OF_NET

Since of_get_mac_address() is now declared even if CONFIG_OF_NET
is not configured, the ifdef is no longer necessary and can be
removed.

Subject: [PATCH 0914/1722] net: fix smatch warnings inside datagram_poll

Commit 7d4c04fc170087119727119074e72445f2bb192b ("net: add option to enable
error queue packets waking select") has an issue due to operator precedence
causing the bit-wise OR to bind to the sock_flags call instead of the result of
the terniary conditional. This fixes the *_poll functions to work properly. The
old code results in "mask |= POLLPRI" instead of what was intended, which is to
only include POLLPRI when the socket option is enabled.

Subject: [PATCH 0919/1722] brcmfmac: minor optimization of
 brcmf_sdbrcm_txpkt() function

When taking care of packet alignment to 64-byte boundary padding may
be added between SDPCM header and CDC data. It clear both SDPCM header
space and padding space. Changed it to only clear padding space. In
filling the SDPCM header it uses unaligned access to set SDPCM software
header, but preceding code assures it is properly aligned.

Subject: [PATCH 0920/1722] brcmfmac: use skb_cow() in brcmf_sdbrcm_txpkt() to
 assure alignment

In brcmf_sdbrcm_txpkt() a new packet is allocated and used to transmit
to firmware freeing up the original packet. However, that packet is
still referenced in firmware-signalling so this would result in a
double free. Using skb_cow() avoids this as the packet reference is
unchanged.

Subject: [PATCH 0921/1722] brcmfmac: determine the wiphy->bands property
 correctly.

Use information from the device to determine the bands property
of the wiphy object. After this change the support of 80211n is
correctly presented in the bands property.

Subject: [PATCH 0926/1722] brcmfmac: allow stopping netif queue for different
 reasons

Currently, the netif queue is only stopped when the bus interface is
giving a push back. This will change soon so prepare the driver by
adding a stop reason and stop/resume the queue accordingly.

Subject: [PATCH 0927/1722] brcmfmac: add definitions for handling sk_buff
 control buffer data

The sk_buff structure contains a control buffer that can be used
by different layers in the networking stack for holding packet
associated information. In brcmfmac it is used to hold firmware
signalling related information.

Subject: [PATCH 0931/1722] brcmfmac: add flow-control mode to firmware
 signalling

Upcoming patches will add firmware signalled flow control. Prepare
by adding the mode, which defaults to disable it. The mode can be
queried by brcmf_fws_fc_active() and set by a module parameter.

Subject: [PATCH 0933/1722] brcmfmac: fix handling sk_buff cleanup upon bus tx
 failure

When firmware-signalling is active the brcmf_txcomplete() does
a free of the sk_buff when transfer to firmware fails in the
bus-specific driver code. However, it should also cleanup the
packet from the hanger. This patch fixes that.

Subject: [PATCH 0934/1722] brcmfmac: avoid error output in receive path

Parsing the tlv upon receiving frames can fail. Instead of printing
an error message, just count the parse failure. On some devices we
receive a lot of invalid tlv signals.

this commit will be squashed.

Subject: [PATCH 0936/1722] brcmfmac: add dedicated log level for low-level
 sdio debugging

The low-level sdio code has a large number of trace and info messages
that are mostly useful looking into bus specific issues. For tracing
higher-level driver functions it is better to have a dedicated level
for low-level sdio debugging.

Subject: [PATCH 0937/1722] brcmfmac: initialize struct brcmf_fws_info fields
 before iovar

If iovar to the firmware fails the firmware-signalling module
does a cleanup for which it needs pointer to struct brcmf_pub, which
it gets from struct brcmf_fws_info::drvr. Assign this field before
doing the tlv iovar.

Subject: [PATCH 0943/1722] iwlwifi: mvm: add per-interface debugfs with
 mac_params file

Use the per-interface debugfs infrastructure to create a
directory and symlink, and add a file containing debug
data related to each virtual interface.

Subject: [PATCH 0944/1722] iwlwifi: mvm: implement reduced Tx power

This allows to have better wifi TPT when BT is active under
good RSSI conditions.
Wifi will have better chance to send Acks and Cts even if BT
is active.

Subject: [PATCH 0945/1722] iwlwifi: mvm: remove BT Coex constraints upon
 roaming to A band

When we roam to A band, we don't need to constraint WiFi
any more since it is operating on a different band.

Subject: [PATCH 0946/1722] iwlwifi: mvm: downgrade to old power management API

Current available FW still doesn't support new PM API.
Therefore, to enable basic power management with the
existing firmware, change the API in the driver back
to the API used in the current firmware.

Subject: [PATCH 0948/1722] iwlwifi: mvm: don't disable power management due to
 P2P device

Currently power management is supported only when only a single
virtual interface is present. The driver verifies number of created
interfaces and disables power management when multiple interfaces
present. However, this rule does not extend to a P2P device that is
handled differently in the firmware. If a P2P device is added power
management can remain enabled.

Subject: [PATCH 0950/1722] iwlwifi: mvm: always send power table command

The driver distinguishes between power management and device's power
down enablement. Power management enablement depends both on driver's
module power parameters and mac80211 decision. The device's power down
depends only on driver's module power parameters. Change the driver to
always send Power Table command to enable or disable both power
management and device's power down.

Subject: [PATCH 0956/1722] iwlwifi: sleep for at least 10 seconds

Many platforms have issues processing a wakeup signal
while they're still suspending, and will ignore it.
Since our device thinks it woke the platform, and the
platform ignored the signal, it will sleep without
WoWLAN being enabled as the device disables WoWLAN
when having woken the platform.

Resolve this by making the device wait for 10 seconds
after getting the suspend signal before waking up the
platform.

Subject: [PATCH 0958/1722] iwlwifi: mvm: beautify code in BT Coex

The iterators don't need to know what bt_kill_msk means.
All they need to know is if reduced Tx power is enabled
on an interface or not. So change the member of the
iterator to be a bool.

Subject: [PATCH 0960/1722] iwlwifi: mvm: clean up invalid station handling

Using IWL_MVM_STATION_COUNT and IWL_INVALID_STATION together
isn't a good idea as they have different values. Always use
IWL_MVM_STATION_COUNT for an invalid station in MVM and move
the definition of the IWL_INVALID_STATION constant into the
DVM driver to avoid making such mistakes again. The one use
in the transport code can be hard-coded to -1 instead as the
station ID is passed as an integer there.

It actually handles a BT coex notification, so rename it
to be more self explained.
Also, this function can always look at mvm->last_bt_notif
provided that the latter is updated on time.

Subject: [PATCH 0963/1722] Bluetooth: Fix HCI request framework

Some HCI commands don't send a Command Complete Event once the HCI
command has completed so they require some special handling from the
HCI request framework. These HCI commands, however, send a Command
Status Event to indicate that the command has been received, and
that the controller is currently performing the task for the command.

So, in order to properly handle those HCI commands, the HCI request
framework should consider the HCI command has completed once the
Command Status Event is received.

This way, we fix some issues regarding the Inquiry command support,
as well as add support for all those HCI commands which would require
some special handling from the HCI request framework.

Subject: [PATCH 0964/1722] Bluetooth: Fix hci_inquiry ioctl usage

Since the HCI request framework was properly fixed, the hci_req_sync
call, in hci_inquiry, will return as soon as the HCI command completes
(not the Inquiry procedure). However, in inquiry ioctl implementation,
we want to sleep the user process until the inquiry procedure finishes.

This patch changes hci_inquiry so, in case the HCI Inquiry command
was executed successfully, it waits the HCI_INQUIRY flag to be cleared.
This way, the user process will sleep until the inquiry procedure
finishes.

Subject: [PATCH 0966/1722] Bluetooth: Fix H4 crash from incoming UART packets

This patch adds a check HCI_UART_REGISTERED before reading UART data in
the HCI UART H4 driver. UART data could arrive when inside the
hci_uart_tty_ioctl function after calling test_and_set_bit for
HCI_UART_PROTO_SET but before the hci_uart_set_proto function has
returned.

Subject: [PATCH 0970/1722] Bluetooth: Add __hci_cmd_sync() helper function

This patch adds a helper function for sending a single HCI command
waiting for its completion and then returning back the parameters in the
resulting command complete event (if there was one).

The implementation is very similar to that of hci_req_sync() except that
instead of invocing a callback for sending HCI commands the function
constructs and sends one itself and after being woken up picks the last
received event from hdev->recv_evt (if it matches the right criteria)
and returns it.

Subject: [PATCH 0971/1722] Bluetooth: Add support for custom event terminated
 commands

This patch adds support for having commands within HCI requests that do
not result in a command complete but some other event. This is at least
needed for some vendor specific commands to be issued in the
hdev->setup() procecure, but might also be useful for other commands.

The way that the support is implemented is by extending the skb control
buffer to have a field to indicate that the command is expected to
terminate with a special event. After sending the command each received
event can then be compared against this field through hdev->sent_cmd.

Subject: [PATCH 0972/1722] Bluetooth: Add __hci_cmd_sync_ev function

This patch adds a __hci_cmd_sync_ev function, analogous to
__hci_cmd_sync except that it also takes an event parameter to indicate
that the command completes with a special event instead of command
complete. Internally this new function takes advantage of the
hci_req_add_ev function introduced in the previous patch.

The primary expected user of this new function are the setup routines of
HCI drivers which may want to send custom commands and return only when
they have completed.

Subject: [PATCH 0973/1722] Bluetooth: Add driver setup stage for early init

Some drivers require a special stage for their early init. This is
always specific to the driver or transport. So call back into driver to
allow bringing up the device.

The advantage with this stage is that the Bluetooth core is actually
handling the HCI layer now. This means that command and event processing
is available.

Subject: [PATCH 0976/1722] net: frag queue per hash bucket locking

This patch implements per hash bucket locking for the frag queue
hash.  This removes two write locks, and the only remaining write
lock is for protecting hash rebuild.  This essentially reduce the
readers-writer lock to a rebuild lock.

This patch is part of "net: frag performance followup"
 http://thread.gmane.org/gmane.linux.network/263644
of which two patches have already been accepted:

Same test setup as previous:
 (http://thread.gmane.org/gmane.linux.network/257155)
 Two 10G interfaces, on seperate NUMA nodes, are under-test, and uses
 Ethernet flow-control.  A third interface is used for generating the
 DoS attack (with trafgen).

Notice, I have changed the frag DoS generator script to be more
efficient/deadly.  Before it would only hit one RX queue, now its
sending packets causing multi-queue RX, due to "better" RX hashing.

Test types summary (netperf UDP_STREAM):
 Test-20G64K     == 2x10G with 65K fragments
 Test-20G3F      == 2x10G with 3x fragments (3*1472 bytes)
 Test-20G64K+DoS == Same as 20G64K with frag DoS
 Test-20G3F+DoS  == Same as 20G3F  with frag DoS
 Test-20G64K+MQ  == Same as 20G64K with Multi-Queue frag DoS
 Test-20G3F+MQ   == Same as 20G3F  with Multi-Queue frag DoS

When I rebased this-patch(03) (on top of net-next commit a210576c) and
removed the _bh spinlock, I saw a performance regression.  BUT this
was caused by some unrelated change in-between.  See tests below.

Test (A) is what I reported before for patch-02, accepted in commit 1b5ab0de.
Test (B) verifying-retest of commit 1b5ab0de corrospond to patch-02.
Test (C) is what I reported before for this-patch

Test (D) is net-next master HEAD (commit a210576c), which reveals some
(unknown) performance regression (compared against test (B)).
Test (D) function as a new base-test.

Performance table summary (in Mbit/s):

(F) without bh: 17471.3   11298.7   3818.05     6102.11     165.7    406.3

Test (E) and (F) is this-patch(03), with(V1) and without(V2) the _bh spinlocks.

I cannot explain the slow down for 20G64K (but its an artificial
"lab-test" so I'm not worried).  But the other results does show
improvements.  And test (E) "with _bh" version is slightly better.

V2:
- By analysis from Hannes Frederic Sowa and Eric Dumazet, we don't
  need the spinlock _bh versions, as Netfilter currently does a
  local_bh_disable() before entering inet_fragment.
- Fold-in desc from cover-mail
V3:
- Drop the chain_len counter per hash bucket.

Subject: [PATCH 0978/1722] netfilter: nf_log: prepare net namespace support
 for loggers

This patch adds netns support to nf_log and it prepares netns
support for existing loggers. It is composed of four major
changes.

1) nf_log_register has been split to two functions: nf_log_register
   and nf_log_set. The new nf_log_register is used to globally
   register the nf_logger and nf_log_set is used for enabling
   pernet support from nf_loggers.

   Per netns is not yet complete after this patch, it comes in
   separate follow up patches.

2) Add net as a parameter of nf_log_bind_pf. Per netns is not
   yet complete after this patch, it only allows to bind the
   nf_logger to the protocol family from init_net and it skips
   other cases.

3) Adapt all nf_log_packet callers to pass netns as parameter.
   After this patch, this function only works for init_net.

4) Make the sysctl net/netfilter/nf_log pernet.

Subject: [PATCH 0979/1722] netfilter: ebt_log: add net namespace support for
 ebt_log

Add pernet support to ebt_log by means of the new nf_log_set
function added in (30e0c6a netfilter: nf_log: prepare net
namespace support for loggers).

Since syslog ns has yet not been implemented, we don't want
the containers to DDOS host's syslogd. So only enable ebt_log
only from init_net and wait for syslog ns support.

Subject: [PATCH 0982/1722] netfilter: ipt_ULOG: add net namespace support for
 ipt_ULOG

Add pernet support to ipt_ULOG by means of the new nf_log_set
function added in (30e0c6a netfilter: nf_log: prepare net
namespace support for loggers).

This patch also make ulog_buffers and netlink socket
nflognl per netns.

Subject: [PATCH 0984/1722] netfilter: enable per netns support for nf_loggers

After this patch, all nf_loggers support net namespace. Still
xt_LOG and ebt_log require syslog netns support.

 support for nfnetlink_queue

This patch makes /proc/net/netfilter/nfnetlink_queue pernet.
Moreover, there's a pernet instance table and lock.

Subject: [PATCH 0986/1722] netfilter: remove unneeded variable
 proc_net_netfilter

Now that this supports net namespace for nflog and nfqueue,
we can remove the global proc_net_netfilter which has no
clients anymore.

Based on patch from Gao feng.

Subject: [PATCH 0988/1722] Bluetooth: hidp: verify l2cap sockets

We need to verify that the given sockets actually are l2cap sockets. If
they aren't, we are not supposed to access bt_sk(sock) and we shouldn't
start the session if the offsets turn out to be valid local BT addresses.

That is, if someone passes a TCP socket to HIDCONNADD, then we access some
random offset in the TCP socket (which isn't even guaranteed to be valid).

Fix this by checking that the socket is an l2cap socket.

Remove useless action PHY_READ_EFUSE, PHY_READ_MAC_BYTE, PHY_WRITE_MAC_BYTE,
PHY_WRITE_ERI_WORD. And define the new action PHY_MDIO_CHG.

PHY_MDIO_CHG is used to modify the mdio operation. By the way, the
firmware could support setting mac ocp.

Date: Mon, 1 Apr 2013 22:23:41 +0000
Subject: [PATCH 0996/1722] r8169: adjust the flow of hw_start

The suggestion as following:
- initial settings or default settings
- rtl_hw_start_xxx. rtl_hw_start_xxx may change some default settings.
- enable tx/rx. This has to be after the above two steps.
- rtl_set_rx_mode. AcceptXXXs have to be enabled after enabling tx/rx.

Subject: [PATCH 1000/1722] net: ethernet: ks8851: use spi_get_drvdata() and

Use the wrapper functions for getting and setting the driver data using
spi_device instead of using dev_{get|set}_drvdata with &spi->dev, so we
can directly pass a struct spi_device.

Subject: [PATCH 1009/1722] selftests: net: add PF_PACKET TPACKET v1/v2/v3
 selftests

This patch adds a simple test case that probes the packet socket's
TPACKET_V1, TPACKET_V2 and TPACKET_V3 behavior regarding mmap(2)'ed
I/O for a small burst of 100 packets. The test currently runs for ...

  TPACKET_V1: RX_RING, TX_RING
  TPACKET_V2: RX_RING, TX_RING
  TPACKET_V3: RX_RING

... and will output on success:

  test: TPACKET_V1 with PACKET_RX_RING .................... 100 pkts (9600 bytes)
  test: TPACKET_V1 with PACKET_TX_RING .................... 100 pkts (9600 bytes)
  test: TPACKET_V2 with PACKET_RX_RING .................... 100 pkts (9600 bytes)
  test: TPACKET_V2 with PACKET_TX_RING .................... 100 pkts (9600 bytes)
  test: TPACKET_V3 with PACKET_RX_RING .................... 100 pkts (9600 bytes)
  OK. All tests passed

Reusable parts of psock_fanout.c have been put into a psock_lib.h
file for common usage. Test case successfully tested on x86_64.

+ * Copyright 2013 Red Hat, Inc.
+ * Author: Daniel Borkmann <dborkman@redhat.com>
+ *
+ * A basic test of packet socket's TPACKET_V1/TPACKET_V2/TPACKET_V3 behavior.
+ *
+ * Control:
+ *   Test the setup of the TPACKET socket with different patterns that are
+ *   known to fail (TODO) resp. succeed (OK).
+ *
+ * Datapath:
+ *   Open a pair of packet sockets and send resp. receive an a priori known
+ *   packet pattern accross the sockets and check if it was received resp.
+ *   sent correctly. Fanout in combination with RX_RING is currently not
+ *   tested here.
+ *
+ *   The test currently runs for
+ *   - TPACKET_V1: RX_RING, TX_RING
+ *   - TPACKET_V2: RX_RING, TX_RING
+ *   - TPACKET_V3: RX_RING

Subject: [PATCH 1010/1722] 802: fix a possible race condition

(Resend with a better changelog)

garp_pdu_queue() should ways be called with this spin lock.
garp_uninit_applicant() only holds rtnl lock which is not
enough here.  A possible race can happen as garp_pdu_rcv()
is called in BH context:

	garp_pdu_rcv()
	  |->garp_pdu_parse_msg()
	    |->garp_pdu_parse_attr()
	      |-> garp_gid_event()

Found by code inspection.

Subject: [PATCH 1012/1722] mac802154: Do not try to resend failed packets

When ops->xmit() fails, drop the packet. Devices which support hardware
ack and retry (which include all devices currently supported by mainline),
will automatically retry sending the packet (in the hardware) up to 3
times, per the 802.15.4 spec.  There is no need, and it is incorrect to
try to do it in mac802154.

Use netif_stop_queue() and netif_wake_queue() to control the flow of
packets to mac802154 devices.  Since many IEEE 802.15.4 devices have no
output buffer, and since the mac802154 xmit() function is designed to
block, netif_stop_queue() is called after each packet.

Subject: [PATCH 1014/1722] mac802154: Increase tx_buffer_len

Increase the buffer length from 10 to 300 packets. Consider that traffic on
mac802154 devices will often be 6LoWPAN, and a full-length (1280 octet)
IPv6 packet will fragment into 15 6LoWPAN fragments (because the MTU of
IEEE 802.15.4 is 127).  A 300-packet queue is really 20 full-length IPv6
packets.

With a queue length of 10, an entire IPv6 packet was unable to get queued
at one time, causing fragments to be dropped, and making reassembly
impossible.

Subject: [PATCH 1015/1722] 6lowpan: handle dev_queue_xmit() error code
 properly

dev_queue_xmit() will return a positive value if the packet could not be
queued, often because the real network device (in our case the mac802154
wpan device) has its queue stopped.  lowpan_xmit() should handle the
positive return code (for the debug statement) and return that value to
the higher layer so the higher layer will retry sending the packet.

Subject: [PATCH 1019/1722] scm: Stop passing struct cred

Now that uids and gids are completely encapsulated in kuid_t
and kgid_t we no longer need to pass struct cred which allowed
us to test both the uid and the user namespace for equality.

Passing struct cred potentially allows us to pass the entire group
list as BSD does but I don't believe the cost of cache line misses
justifies retaining code for a future potential application.

Subject: [PATCH 1024/1722] mac80211: remove ancient reference to master
 interface

The master interface no longer exists ... and hasn't for
a few years now, so remove this reference :-)

There's no need to parse IEs that aren't used
so just remove them.

Subject: [PATCH 1029/1722] mac80211: fix the PREP mesh hwmp debug message

The mesh hwmp debug message is a bit confusing. The "sending PREP
to %p" should be the MAC address of mesh STA that has originated
the PREQ message and the "received PREP from %pM" should be the MAC
address of the mesh STA that has originated the PREP message.

Subject: [PATCH 1030/1722] mac80211: return new mpath from mesh_path_add()

Most times that mesh_path_add() is called, it is followed by
a lookup to get the just-added mpath.  We can instead just
return the new mpath in the case that we allocated one (or the
existing one if already there), so do that.  Also, reorder the
code in mesh_path_add a bit so that we don't need to allocate
in the pre-existing case.

Subject: [PATCH 1032/1722] mac80211: purge remain-on-channel items when
 suspending

They can't really be executed while suspended and could
trigger work warnings, so abort all ROC items. When the
system resumes the notifications about this will be
delivered to userspace which can then act accordingly
(though it will assume they were canceled/finished.)

doesn't have to happen later when it's removed.

Subject: [PATCH 1034/1722] mac80211: fix do_stop handling while suspended

When a device is unplugged while suspended, mac80211 is
de-initialized and all interfaces are removed while no
state is actually present in the driver. This can cause
warnings and driver confusion.

Fix this by reordering the do_stop code to not call the
driver when it is suspended, i.e. when there's no state
in the driver anyway.

The previous patches removed a few corner cases in ROC
and virtual monitor interfaces so that now this is safe
to do and no state should be left over.

Subject: [PATCH 1035/1722] mac80211: disable uAPSD if all ACs are under ACM

It's unlikely that an AP requires WMM mandatory admission control
for all access categories, and if it does then we still transmit
on the background AC without requesting admission. However, avoid
using uAPSD in this case since the implementation could run into
issues and might use other ACs etc.

Subject: [PATCH 1036/1722] mac80211: don't fiddle with netdev queues in MLME
 code

The netdev queues should always represent the state that
the driver gave them, so fiddling with them isn't really
appropriate in the mlme code. Also, since we stop queues
for flushing now, this really isn't necessary any more.

As the scan/offchannel code has also been modified to no
longer do this a while ago, remove the outdated smp_mb()
and comments about it.

While at it, also add a pair of braces that was missing.

Subject: [PATCH 1038/1722] mac80211: don't start new netdev queues if driver
 stopped

If a new netdev (e.g. an AP VLAN) is created while the driver
has queues stopped, the new netdev queues will be started even
though they shouldn't. This will lead to frames accumulating
on the internal mac80211 pending queues instead of properly
being held on the netdev queues.

Subject: [PATCH 1043/1722] iwlwifi: print warning on request_module failure

If request_module() failed then we didn't have the correct
opmode module that the driver needs to function, so print
a warning in this case to make it more obvious what could
be wrong. This still won't catch the case where the module
simply doesn't exist because it wasn't compiled though.

 nvm_data->valid_tx_ant

In commit 332235427a566d8be04b9676a7ac380c8853aa9b
"iwlwifi: mvm: take the valid_{rx,tx}_ant from the TLV"

I replaced the access to nvm_data->valid_tx_ant to an inline
cheking the TLV flags but forgot a few occurences. Fix that.

Subject: [PATCH 1045/1722] iwlwifi: dvm: handle FLUSH ampdu actions from
 mac80211

Until now we didn't handle properly the FLUSH ampdu action
coming from mac80211. This could result in SCD queue leak:
mac80211 would STOP_FLUSH an AMPDU Tx session and remove
the station. If we had still packets on the ring, we
wouldn't deallocate the SCD queue and wait for it to be
empty.
The indication of the queue being empty comes from the Tx
response flow which relies on the tid_data structure. The
problem is that this structure has been cleared when the
station has been removed.
In order to solve this issue, block in the STOP_FLUSH
ampdu_action until the SCD queue is flushed, and only then,
let mac80211 move forward to remove the station.
iwlagn_txfifo_flush had to be enhanced to allow this.

The bug fixed here caused the "txq_id mismatch: 12 0" print.

Subject: [PATCH 1046/1722] IEEE 802.15.4: remove get_bsn from "struct
 ieee802154_mlme_ops"

It served no purpose: we never call it from anywhere in the stack
and the only driver that did implement it (fakehard) merely provided
a dummy value.

There is also considerable doubt whether it would make sense to
even attempt beacon processing at this level in the Linux kernel.

Date: Thu, 4 Apr 2013 06:32:35 +0000
Subject: [PATCH 1047/1722] ieee802154/nl-mac.c: make some MLME operations
 optional

Check for NULL before calling the following operations from "struct
ieee802154_mlme_ops": assoc_req, assoc_resp, disassoc_req, start_req,
and scan_req.

This fixes a current oops where those functions are called but not
implemented. It also updates the documentation to clarify that they
are now optional by design. If a call to an unimplemented function
is attempted, the kernel returns EOPNOTSUPP via netlink.

The following operations are still required: get_phy, get_pan_id,
get_short_addr, and get_dsn.

Note that the places where this patch changes the initialization
of "ret" should not affect the rest of the code since "ret" was
always set (again) before returning its value.

Subject: [PATCH 1050/1722] ip_gre: fix a possible crash in parse_gre_header()

pskb_may_pull() can change skb->head, so we must init iph/greh after
calling it.

Bug added in commit c54419321455 (GRE: Refactor GRE tunneling code.)

Hi Greg,

I'm unsure if you or Dave should take that one as it's for one a TTY
patch but also living under net/. So I'm uncertain and let you decide!

Thanks,
Mathias

Subject: [PATCH] TTY: ircomm, use GFP_KERNEL in ircomm_open()

We're clearly running in non-atomic context as our only call site is
able to call wait_event_interruptible(). So we're safe to use GFP_KERNEL
here instead of GFP_ATOMIC.

Subject: [PATCH 1054/1722] mrf24j40: Enable link-layer acknowledgement and
 retry

On the MRF24J40, link-layer acknowledgment request and retry must be
turned on explicitly for each packet.  Turn this on in the hardware based
on the FC_ACK_REQ bit being set in the packet.

Also, now that failure to receive an ACK will cause the hardware to report
failure of transmission, change the log level for this failure to debug
level.

2. net/mac802154/mib.c: Lock (pib_lock) accesses to current_channel and

Subject: [PATCH 1056/1722] mwifiex: fix negative cmd_pending count

cmd_pending is increased in mwifiex_wait_queue_complete() and
decreased in mwifiex_complete_cmd() currently.
If there are two or more commands in the cmd_pending_q the main
worker thread will pick up next command from cmd_pending_q
automatically after finishing current command. As a result
mwifiex_wait_queue_complete() will not be called because
the command is alreay completed. This leads to a negative
number in cmd_pending count.

Fix it by increasing cmd_pending when a cmd is queued into
cmd_pending_q and decreasing when that cmd is recycled. For scan
commands we don't perform inc/dec operations until it's moved
from scan_pending_q to cmd_pending_q. This covers both
synchronous and asynchronous commands.

Subject: [PATCH 1060/1722] ath9k: add support for DFS master mode

These are the remaining knobs in ath9k to support DFS:
* mark AR9280 and AR9580 as DFS tested
* synchronize DFS regulatory domain to reg notifyer
* set required RX filter flags for radar detection
* process radar PHY errors at DFS detector
* notify DFS master on radar detection

DFS support requires CONFIG_ATH9K_DFS_CERTIFIED to be set.

adapter->bss_prio_tbl list has already been checked in outer loop.
The inner loop works with priv_tmp->wmm.tid_tbl_ptr list. Also the
lock taken, gives hint that this is likely a copy-paste error.

ra_list_spinlock is used to protect struct mwifiex_wmm_desc and
embedded structures such as ra_list. tid_tbl_lock while more fine
grained, is not used but in one function. That function is not
called reentrantly. To protect ra_list from concurrent modification
ra_list_spinlock must be held.

Subject: [PATCH 1065/1722] mwifiex: fix infinite loop by removing
 NO_PKT_PRIO_TID

Using NO_PKT_PRIO_TID and tx_pkts_queued to check for an empty
state, can lead to a contradictory state, resulting in an
infinite loop. Currently queueing and dequeuing of packets is
not synchronized, and can happen concurrently. While tx_pkts_queued
is incremented when adding a packet, max prio is set to NO_PKT when
the WMM list is empty. If a packet is added right after the check
for empty, but before setting max prio to NO_PKT, that packet is
trapped and creates an infinite loop.

Because of the new packet, tx_pkts_queued is at least 1, indicating
wmm lists are not empty. Opposing that max prio is NO_PKT, which
means "skip this wmm queue, it has no packets". The infinite loop
results, because the main loop checks the wmm lists for not empty
via tx_pkts_queued, but for dequeing it uses max_prio to see if it
can skip current list. This will never end, unless a new packet is
added which will restore max prio to the level of the trapped packet.

The solution here is to rely on tx_pkts_queued solely for checking
wmm queue to be empty, and drop the NO_PKT define. It does not
address the locking issue.

Subject: [PATCH 1066/1722] mwifiex: hold proper locks when accessing ra_list /
 bss_prio lists

Not locking ra_list when dequeuing packets creates race conditions.
When adding a packet 'tx_pkts_queued' is modified before setting
highest_priority_queue. If in-between the main loop starts, it will
see a packet queued (tx_pkts_queued > 0) but will not find it, since
max prio is not set yet. Depending on the scheduling, the thread
trying to add the packet could complete and restore the situation.
But this is not something to rely on.

Another race condition exists, if a new packet, exceeding current
max prio is added. If concurrently a packet is dequeued, the newly
set max prio will be overwritten with the value of the dequeued
packet. This can occur, because selecting a packet and modifying
the max prio is not atomic. The result in an infinite loop unless,
a new packet is added that has at least the priority of the hidden
packet.

Same applies to bss_prio_tbl. Forward iteration is no proper
lock-free technique and provides no protection from calls to
list_del. Although BSS are currently not added/removed dynamically,
this must not be the case in the future. Hence always hold proper
locks when accessing those lists.

Subject: [PATCH 1068/1722] brcmfmac: handle firmware signalling destination
 entry state

Firmware can signal whether the host driver may sent packets for
a specific destination or interface. This can happen when a
destination is sleeping or when going off-channel.

Subject: [PATCH 1069/1722] brcmfmac: handle firmware signals requesting for
 packets

The firmware can request the host driver for packets, by sending
either the MAC_REQUEST_CREDIT or the MAC_REQUEST_PACKET primitive.
This patch adds handling of these primitives.

Subject: [PATCH 1074/1722] brcmfmac: remove condition for calling event
 handler

In fweh module the event handler was only called if the
struct brcmf_if instance had a non-null netdev associated.
This restriction is no longer valid for P2P_DEVICE type
of interface. This patch removes that restriction.

With the introduction of the P2P_DEVICE interface type an instance of
struct wireless_dev does not always have a netdev assigned to it. Better
use container_of() construct to obtain internal structure and go from
there.

From 27f10e380ad912c7928e08c4d04b246e66022cc4 Mon Sep 17 00:00:00 2001
From: Arend van Spriel <arend@broadcom.com>
Date: Fri, 5 Apr 2013 10:57:50 +0200
Subject: [PATCH 1078/1722] brcmfmac: support creation of P2P_DEVICE through
 user-space

The current driver code creates a P2P_DEVICE through a module
parameter. This device has a dummy netdevice which is not how this
interface type is intended. This patch add proper support for the
P2P_DEVICE interface type. This requires a wpa_supplicant with such
support as well.

Subject: [PATCH 1079/1722] brcmfmac: wait for firmware event when creating
 P2P_DEVICE interface

The firmware sends a IF event to notify the host driver that the
P2P_DEVICE interface has been created. Wait for the event before
returning the related wireless_dev.

Subject: [PATCH 1081/1722] brcmfmac: obtain wdev using vif object in action
 frame rx

The function brcmf_p2p_notify_action_frame_rx() the wireless_dev
is needed to pass the action frame to cfg80211. The wireless_dev
is held in brcmf_cfg80211_vif object. Use that instead of the
ieee80211_ptr in net_device as P2P_DEVICE interface does not have
a net_device associated with it.

Subject: [PATCH 1082/1722] brcmfmac: only use ifidx from BDC header in
 brcmf_rx_frames()

In brcmf_rx_frames() the call to brcmf_fweh_process_skb() could
change the ifidx using information in the event data. This is
only different to the BDC ifidx for IF ADD event. However, the
creation of the new interface is deferred to event worker so
it does not exist. After brcmf_fweh_process_skb() it is only
used to set statistics.

Subject: [PATCH 1086/1722] net: of_mdio: scan mdiobus for PHYs without reg
 property

Using DT for mdiobus and ethernet-phy requires to know the PHY address, which
is hard to guess if you don't know it. This patch extends of_mdiobus_register
to scan mdiobus for PHYs if reg property of the corresponding node is not set.
This also allows to have phy nodes in SoC DT files where the reg property can
be overwritten in the board file later. To encourage people to finally set the
actual phy address, the mdiobus scan is noisier than required.

for example, there were some new fields (in the driver
module parameter section) and the ptp files were
not documented.

From ceb694997e1b5d45627553ac7b1f88ff16cb9507 Mon Sep 17 00:00:00 2001
From: Giuseppe CAVALLARO <peppe.cavallaro@st.com>
Date: Mon, 8 Apr 2013 02:10:01 +0000
Subject: [PATCH 1090/1722] stmmac: code tidy-up

This patch tidies up the code. I have run Linden (and verified with checkpatch)
many part of the driver trying to reorganize some sections respecting the
codying-style rules in the points where it was not done.

Subject: [PATCH 1091/1722] stmmac: review private structure fields

recently many new supports have been added in the stmmac driver w/o taking care
about where each new field had to be placed inside the private structure for
guaranteeing the best cache usage.
This is what I wanted in the beginning, so this patch reorganizes all the fields
in order to keep adjacent fields for cache effect.
I have also tried to optimize them by using pahole.

V2: do not abuse with ____cacheline_aligned_in_smp and keep fields that
potentially could stay in the same cache-line for better usage in SMP systems.

Subject: [PATCH 1093/1722] net: ipv6: add tokenized interface identifier
 support

This patch adds support for IPv6 tokenized IIDs, that allow
for administrators to assign well-known host-part addresses
to nodes whilst still obtaining global network prefix from
Router Advertisements. It is currently in draft status.

  The primary target for such support is server platforms
  where addresses are usually manually configured, rather
  than using DHCPv6 or SLAAC. By using tokenised identifiers,
  hosts can still determine their network prefix by use of
  SLAAC, but more readily be automatically renumbered should
  their network prefix change. [...]

  The disadvantage with static addresses is that they are
  likely to require manual editing should the network prefix
  in use change.  If instead there were a method to only
  manually configure the static identifier part of the IPv6
  address, then the address could be automatically updated
  when a new prefix was introduced, as described in [RFC4192]
  for example.  In such cases a DNS server might be
  configured with such a tokenised interface identifier of
  ::53, and SLAAC would use the token in constructing the
  interface address, using the advertised prefix. [...]

  http://tools.ietf.org/html/draft-chown-6man-tokenised-ipv6-identifiers-02

The implementation is partially based on top of Mark K.
Thompson's proof of concept. However, it uses the Netlink
interface for configuration resp. data retrival, so that
it can be easily extended in future. Successfully tested
by myself.

+Network classifier cgroup
+-------------------------
+
+The Network classifier cgroup provides an interface to
+tag network packets with a class identifier (classid).
+
+The Traffic Controller (tc) can be used to assign
+different priorities to packets from different cgroups.
+
+Creating a net_cls cgroups instance creates a net_cls.classid file.
+This net_cls.classid value is initialized to 0.
+
+You can write hexadecimal values to net_cls.classid; the format for these
+values is 0xAAAABBBB; AAAA is the major handle number and BBBB
+is the minor handle number.
+Reading net_cls.classid yields a decimal result.
+
+Example:
+mkdir /sys/fs/cgroup/net_cls
+mount -t cgroup -onet_cls net_cls /sys/fs/cgroup/net_cls
+mkdir /sys/fs/cgroup/net_cls/0
+echo 0x100001 >  /sys/fs/cgroup/net_cls/0/net_cls.classid
+	- setting a 10:1 handle.
+
+cat /sys/fs/cgroup/net_cls/0/net_cls.classid
+1048577
+
+configuring tc:
+tc qdisc add dev eth0 root handle 10: htb
+
+tc class add dev eth0 parent 10: classid 10:1 htb rate 40mbit
+ - creating traffic class 10:1
+

Receiving unhandled notifications is most certainly not an error
and should not be logged as one.  Knowing that the device sends
notifications we don't handle is useful for developers, but there
is very little a user can do about this.  The message is therefore
just annoying noise to most users with devices sending unhandled
notifications like e.g. USB_CDC_NOTIFY_RESPONSE_AVAILABLE

Subject: [PATCH 1097/1722] net: ipv6: also allow token to be set when device
 not ready

When we set the iftoken in inet6_set_iftoken(), we return -EINVAL
when the device does not have flag IF_READY. This is however not
necessary and rather an artificial usability barrier, since we
simply can set the token despite that, and in case the device is
ready, we just send out our rs, otherwise ifup et al. will do
this for us anyway.

Subject: [PATCH 1098/1722] net: ipv6: only invalidate previously tokenized
 addresses

Instead of invalidating all IPv6 addresses with global scope
when one decides to use IPv6 tokens, we should only invalidate
previous tokens and leave the rest intact until they expire
eventually (or are intact forever). For doing this less greedy
approach, we're adding a bool at the end of inet6_ifaddr structure
instead, for two reasons: i) per-inet6_ifaddr flag space is
already used up, making it wider might not be a good idea,
since ii) also we do not necessarily need to export this
information into user space.

Subject: [PATCH 1103/1722] net: sctp: introduce uapi header for sctp

This patch introduces an UAPI header for the SCTP protocol,
so that we can facilitate the maintenance and development of
user land applications or libraries, in particular in terms
of header synchronization.

To not break compatibility, some fragments from lksctp-tools'
netinet/sctp.h have been carefully included, while taking care
that neither kernel nor user land breaks, so both compile fine
with this change (for lksctp-tools I tested with the old
netinet/sctp.h header and with a newly adapted one that includes
the uapi sctp header). lksctp-tools smoke test run through
successfully as well in both cases.

Subject: [PATCH 1104/1722] tg3: Fix flow control settings not propagated to
 hardware

In tg3_setup_copper_phy(), if autonegotiation is disabled, we need to
relink only if the speed or duplex does not match the configured
setting.  If flow control does not match, a relink is not necessary as
flow control is not a PHY setting.  Later on, we'll call
tg3_setup_flow_ctrl() to set up the MAC to the desired flow control
settings if we're in full duplex mode.

The STM45PE20 pinstrap on 5762 devices supports multiple sizes. So treat
it just like the ST45_USPT and the size will be read from 0xf0 via
tg3_get_nvram_size().

Subject: [PATCH 1110/1722] tg3: Add support for link flap avoidance

This patch and the following two patches add support for link flap avoidance
by maintaining the link on power down. This feature is required for
management capable devices to have the management connection
uninterrupted on driver reload, reboot and interface up/down.

The other pros of this feature are
 - It speeds up boot up time by several seconds as DHCP addresses can be
   acquired faster.
 - It avoids lengthy Spanning Tree delay.

On powerup the hardware brings up the phy with default settings. If the
link is not up, the management software configures the phy to gigabit
and starts autonegotiate. Subsequently, as long as the link is up, the
driver and management refrain from resetting and/or changing any
configuration that the link depends on.

The LNK_FLAP_AVOID setting is an NVRAM user configurable bit and is
disabled by default.  If this setting is enabled, we skip powering down
the phy and resetting it.

A second NVRAM setting is 1G_ON_VAUX_OK (off by default). This adds
support for gigabit link speed when device is on auxiliary power.

Subject: [PATCH 1111/1722] tg3: Pull the phy advertised speed and flow control
 settings on driver load

Normally on driver load, we set the default settings for speed and flow
control. However, if the default setting is not compatible with the current link
state, we would autonegotiate and cause a link flap. To avoid this, we
pull the current advertised settings into the config.

A second scenario is if a user changes the speed/duplex/fc settings when
the interface is down. In this case we must not pull the settings from
the phy and overwrite user settings. We avoid that by checking the
USER_CONFIGURED flag.

Date: Tue, 9 Apr 2013 10:18:14 +0000
Subject: [PATCH 1115/1722] tg3: Use bool not int

Using bool can make code more readable.

Convert uses and tests of int to bool.

This also makes a comparison of tg3->link_up
(itself bool) a bool comparison instead of int.

Reorder stack variable declarations to make
bool fit declaration holes where appropriate.

From 58959bdcb08e82b0212b27202e74744f3cebc4d6 Mon Sep 17 00:00:00 2001
From: Gabor Juhos <juhosg@openwrt.org>
Date: Fri, 5 Apr 2013 08:27:00 +0200
Subject: [PATCH 1116/1722] rt2x00: rt2x00mmio: use rt2x00mmio prefix in
 function names

The functions in the rt2x00mmio module has been
moved from the rt2x00pci module. Each function
uses the rt2x00pci prefix which is a bit confusing.
Use the r2x000mmio prefix for each function to make
it consistent with the module name.

The renamed functions are used by several modules,
and updating the names in all of them would result
in a big patch. In order to keep the patch simple,
add compatibility defines for the old function
names. This allows to update the names in each
module separately. After each module is updated,
the defines can be removed.

The patch contains no functional changes.

From 172c5911a0b44c344637556726d8638587632e3c Mon Sep 17 00:00:00 2001
From: Gabor Juhos <juhosg@openwrt.org>
Date: Fri, 5 Apr 2013 08:27:01 +0200
Subject: [PATCH 1117/1722] rt2x00: rt2400pci: use the rt2x00mmio_* routines

Use the recently introduced rt2x00mmio_* routines
instead of the rt2x00pci_* variants.

The patch contains no functional changes.

From c517123a0ee98c9d41d09b1984cafce176d5858f Mon Sep 17 00:00:00 2001
From: Gabor Juhos <juhosg@openwrt.org>
Date: Fri, 5 Apr 2013 08:27:02 +0200
Subject: [PATCH 1118/1722] rt2x00: rt2500pci: use the rt2x00mmio_* routines

Use the recently introduced rt2x00mmio_* routines
instead of the rt2x00pci_* variants.

The patch contains no functional changes.

Date: Fri, 5 Apr 2013 08:27:03 +0200
Subject: [PATCH 1119/1722] rt2x00: rt61pci: use the rt2x00mmio_* routines

Use the recently introduced rt2x00mmio_* routines
instead of the rt2x00pci_* variants.

The patch contains no functional changes.

From b9570b66876039620aa36de4eab57f16443e1e18 Mon Sep 17 00:00:00 2001
From: Gabor Juhos <juhosg@openwrt.org>
Date: Fri, 5 Apr 2013 08:27:04 +0200
Subject: [PATCH 1120/1722] rt2x00: rt2800pci: use the rt2x00mmio_* routines

Use the recently introduced rt2x00mmio_* routines
instead of the rt2x00pci_* variants.

The patch contains no functional changes.

Subject: [PATCH 1121/1722] rt2x00: rt2x00mmio: remove unused rt2x00pci_*
 defines

All users are converted to use the rt2x00mmio_*
functions so remove the now unused defines.

The patch contain no functional changes.

Subject: [PATCH 1122/1722] ath9k_hw: clean up RF Bank6 handling on
 AR5416/AR91xx

There are two sets of initvals for this RF bank, one with TPC support and
one without.
The TPC one always gets used, so remove the other one to avoid confusion.

Subject: [PATCH 1126/1722] ath9k: fix handling of broken descriptors

As the comment in ath_get_next_rx_buf indicates, if a descriptor with
the done bit set follows one with the done bit cleared, both descriptors
should be discarded, however the driver is not doing that yet.

To fix this, use the rs->rs_more flag as an indicator that the following
frame should be discarded. This also helps with the split buffer case:
if the first part of the frame is discarded, the following parts need to
be discarded as well, since they contain no valid header or usable data.

Subject: [PATCH 1127/1722] ath9k: detect more kinds of invalid descriptors

If AR_CRCErr, AR_PHYErr, AR_DecryptCRCErr or AR_MichaelErr is indicated
in the rx status word, but AR_RxFrameOK is also set, the descriptor
contents are typically invalid. This can show up as a warning about
invalid MCS rates in a frame. Even with those checks in place, a
descriptor with invalid MCS rates can still sometimes make it through to
the driver (mostly on older hardware like AR91xx).

Detect such errors in the last descriptor of a frame and discard the
whole frame if present.

Subject: [PATCH 1128/1722] ath9k: implement buffer holding handling for EDMA
 FIFO

Inside one FIFO slot queue, EDMA chipsets have the same link pointer
re-read race condition as older chipsets, so the same buffer holding
logic needs to be used in order to avoid use-after-free bugs.
Unlike on older chips, it can be skipped for the end of the queue.

Subject: [PATCH 1134/1722] mac80211: fix recalc_radar hwconf sync problem

local->hw.conf maybe not be synced when recalcing whether radar is
enabled, sometimes leaving radar enabled even if it's not neccesary
anymore.

Fix this by:
 * setting radar_enabled when creating the chanctx
 * turning radar_enabled off before destroying the last channel context

Subject: [PATCH 1136/1722] mac80211: always advertise STBC/MCSes even if no AP
 support

Advertise STBC capabilities and MCS rates even if the AP
doesn't support them. This has always been the right thing
to do, but used to be problematic with some APs. Now WFA
testing requires this so re-enable it, problematic APs
would then presumably not pass the test and be fixed.

Subject: [PATCH 1137/1722] mac80211: provide SSID in IBSS mode

Some drivers need SSID in AP and IBSS mode. AP SSID is provided
through BSS_CHANGED_SSID notification. There was no easy way to
do the same for IBSS. In IBSS mode SSID is known but was not
stored in BSS configuration. Extend the AP-mode functionality
to also work in IBSS mode.

Subject: [PATCH 1143/1722] mac80211: always pick a basic rate to tx RTS/CTS
 for pre-HT rates

When the 1st rate control entry is a pre-HT rate we want to set
rts_cts_rate_idx "as the fastest basic rate that is not faster than the
data rate"(code comments).
But in case some bss allowed rate indexes are lower than the lowest bss
basic rate, if the rate control selects a rate among the formers for its
1st rate control entry, rts_cts_rate_idx remains 0 and is not a basic
rate index.
This commit sets rts_cts_rate_idx to the lowest bss basic rate index in
this situation.

Note that the code assumes that lowest indexes == lowest bitrates.

link goes down. That way, nfc_llcp_getsockopt won't return values corresponding
to the previous link parameters.

Depends on timing division by zero can happen when user stops
polling.

pn533_stop_poll() resets modulation counter on stop_poll, but
meanwhile we get response for last poll request and try, despite
of stop poll request, to schedule next modulation for polling.

Subject: [PATCH 1158/1722] NFC: pn533: Optimise issued cmd context tracking

Use struct pn533_cmd instead of pn533_send_async_complete_arg
to track the context of the issued cmd.

This way pn533_send_async_complete_arg struct is no needed
anymore. Just move issuer complete callback to pn533_cmd struct.

Subject: [PATCH 1162/1722] NFC: pn533: Simplify __pn533_send_frame_async

In all cases (send_cmd_async, send_data_async and send_sync)
pn533_send_async_complete() handles all responses internally,
so there is no need to pass this as a callback.

Cmd context is passed to __pn533_send_frame_async in all the
cases as well. It's already kept in struct pn533 which is
available all the time the device is attached. So we can make
use of it instead.

Therefore, cmd_complete and cmd_complete_arg are no needed any more.

Subject: [PATCH 1167/1722] NFC: pn533: Add support for ACS ACR122U reader

ACS ACR122U is an USB NFC reader, PC/SC and CCID compilant, based
on NXP PN532 chip.

Internally, it's build of MCU, PN532 and an antenna. MCU makes the
device CCID and PC/SC compilant and provide USB connection.

In this achitecture, a host cannot talk directly to PN532 and must
rely on MCU. Luckily, MCU exposes pseud-APDU through PC/SC Escape
mechanism which let the host to transmit standard PN532 commands
directly to PN532 chip with some limitations.

The frame roughly looks like:

    CCID header    |          APDU header           |    PN532 header
(pc_to_rdr_escape) |  (pseudo apdu Direct Tramsmit) | (len, TFI, cmd, params)

Accordign to limitations, ACR122U does't provide any mechanism to
abort last issued command.

Subject: [PATCH 1168/1722] NFC: pn533: Add pn533_abort_cmd procedure

pn533_abort_cmd() aborts last command sent to the controller
and cancels already requested urb.

As ACR122U does not support any mechanism (as ACK for standard
PN533) which aborts last command this cannot be issued for this
device. Otherwise, acr122u will behave in an unstable way.

Subject: [PATCH 1177/1722] Bluetooth: Use separate function for BCM92035
 vendor setup

Trying to squeeze every single vendor setup routine into the same function
and have it assigned all the time is actually a bad idea. Especially since
the core can handle the absence of a setup routine perfectly fine.

To make this a lot simpler for future additions of vendor setup code,
split the BCM92035 setup into its own function and only assign it when
this specific device has been detected.

Doing it like this has the nice side benefit that we do not have to keep
a copy of the driver_info around.

Subject: [PATCH 1178/1722] Bluetooth: rename hci_conn_put to hci_conn_drop

We use _get() and _put() for device ref-counting in the kernel. However,
hci_conn_put() is _not_ used for ref-counting, hence, rename it to
hci_conn_drop() so we can later fix ref-counting and introduce
hci_conn_put().

hci_conn_hold() and hci_conn_put() are currently used to manage how long a
connection should be held alive. When the last user drops the connection,
we spawn a delayed work that performs the disconnect. Obviously, this has
nothing to do with ref-counting for the _object_ but rather for the
keep-alive of the connection.

But we really _need_ proper ref-counting for the _object_ to allow
connection-users like rfcomm-tty, HIDP or others.

This patch fixes decrementing SCO connection reference right after
stablishing the SCO connection with defer setup enabled. The dump below
shows a disconnection command with handle 0, the connection is still in
BT_CONNECT2 state and there isn't a handle associated with it.

Subject: [PATCH 1180/1722] Bluetooth: Use GFP_KERNEL in sco_conn_add

This patch changes the memory allocation flags in the sco_conn_add
function, replacing the type to GFP_KERNEL. This function is executed
in process context and it is not called inside an atomic section.

Subject: [PATCH 1183/1722] Bluetooth: Reject SCO when hci connection timeouts

This patch sends Reject Synchronous Connection Request Command when
hci_conn_timeout is triggered, and the SCO connection is in BT_CONNECT2
state. It prevents inconsistency if the remote host doesn't implement
properly the timeout for the connection request, and it removes the
connection reference left when the socket is closed for incoming SCO
connections.

This patch introduces the API of usbnet_link_change, so that
usbnet can handle link change centrally, which may help to
implement killing traffic URBs for saving USB bus bandwidth
and host controller power.

Subject: [PATCH 1194/1722] usbnet: handle link change

The link change is detected via the interrupt pipe, and bulk
pipes are responsible for transfering packets, so it is reasonable
to stop bulk transfer after link is reported as off.

Two adavantages may be obtained with stopping bulk transfer
after link becomes off:

- USB bus bandwidth is saved(USB bus is shared bus except for
USB3.0), for example, lots of 'IN' token packets and 'NYET'
handshake packets is transfered on 2.0 bus.

- probabaly power might be saved for usb host controller since
cancelling bulk transfer may disable the asynchronous schedule of
host controller.

With this patch, when link becomes off, about ~10% performance
boost can be found on bulk transfer of anther usb device which
is attached to same bus with the usbnet device, see below
test on next-20130410:

- read from usb mass storage(Sandisk Extreme USB 3.0) on pandaboard
with below command after unplugging ethernet cable:

	dd if=/dev/sda iflag=direct of=/dev/null bs=1M count=800

Subject: [PATCH 1196/1722] net/mlx4_core: Translate guest B0 steering rules to
 DMFS

The different steering modes are global to the device, with DMFS
being introduced after SRIOV was merged. Hence, SRIOV guests running
legacy / older Linux kernels or non-Linux drivers may provide
B0 steering directives when the hypervisor is using DMFS and fail.

Under B0 only L2 steering rules are allowed, hence B0 is a subset of DMFS.
Use this fact to enable such legacy guests to run by modifying the SRIOV
B0 steering wrapper to translate guest B0 directives to DMFS ones when
the device uses DMFS. The translated B0 rule has to be kept in the
resource tracker as a B0 object to allow for lookup in case of detach.

Subject: [PATCH 1198/1722] vhost_net: remove tx polling state

After commit 2b8b328b61c799957a456a5a8dab8cc7dea68575 (vhost_net: handle polling
errors when setting backend), we in fact track the polling state through
poll->wqh, so there's no need to duplicate the work with an extra
vhost_net_polling_state. So this patch removes this and make the code simpler.

This patch also removes the all tx starting/stopping code in tx path according
to Michael's suggestion.

Netperf test shows almost the same result in stream test, but gets improvements
on TCP_RR tests (both zerocopy or copy) especially on low load cases.

Tested between multiqueue kvm guest and external host with two direct
connected 82599s.

zerocopy disabled:

This patch adds an optional shared block clock to avoid lockups on
clock gated controllers. Besides the new clock, clock handling for
existing clocks is cleaned up and moved to devm_clk_get. Device
tree binding documentation is updated for the new clocks property.

Subject: [PATCH 1202/1722] virtio-net: initialize vlan_features

There's nothing that prevent passing the device features of virtio_net to its
vlan device. So this patch simply passes those to vlan device to benefit from
advanced features.

Netperf shows better sending performance for vlan device since TSO can work on
vlan now.

Subject: [PATCH 1203/1722] tuntap: initialize vlan_features

The vlan_features was zero which prevents vlan GSO packets to be transmitted to
userspace. This is suboptimal so enable this by initialize vlan_features for
tuntap.

Netperf shows better performance of guest receiving since vlan TSO works for
tuntap:

Convert  use of devm_request_and_ioremap() to the newly introduced
devm_ioremap_resource() which provides more consistent error handling.

devm_ioremap_resource() provides its own error messages so all explicit
error messages can be removed from the failure code paths.

It causes build regressions, as per Stephen Rothwell:

====================
After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

Subject: [PATCH 1209/1722] NFC: RFKILL support

All NFC devices will now get proper RFKILL support as long as they provide
some dev_up and dev_down hooks. Rfkilling an NFC device will bring it down
while it is left to userspace to bring it back up when being rfkill unblocked.
This is very similar to what Bluetooth does.

Subject: [PATCH 1212/1722] brcmfmac: move chip download state code to
 sdio_chip.c

enter/exit download state routine is going to diverge with new ARM core
introduced. Move corresponding code to sdio_chip.c for new ARM core support.

Subject: [PATCH 1220/1722] brcmfmac: define and use platform specific data for
 SDIO.

This patch adds support for platform specific data for SDIO
fullmac devices. Currently OOB interrupts are configured by Kconfig
BRCMFMAC_SDIO_OOB but that is now determined dynamically by checking
availibility of platform data.

+ * strength, the exact drive strength which will be used depends on the
+ * capabilities of the device.
+ *
+ * oob_irq_supported: does the board have support for OOB interrupts. SDIO
+ * in-band interrupts are relatively slow and for having less overhead on
+ * interrupt processing an out of band interrupt can be used. If the HW
+ * supports this then enable this by setting this field to true and configure
+ * the oob related fields.
+ *
+ * oob_irq_nr, oob_irq_flags: the OOB interrupt information. The values are
+ * used for registering the irq using request_irq function.
+ *
+ * power_on: This function is called by the brcmfmac when the module gets
+ * loaded. This can be particularly useful for low power devices. The platform
+ * spcific routine may for example decide to power up the complete device.
+ * If there is no use-case for this function then provide NULL.
+ *
+ * power_off: This function is called by the brcmfmac when the module gets
+ * unloaded. At this point the device can be powered down or otherwise be reset.
+ * So if an actual power_off is not supported but reset is then reset the device
+ * when this function gets called. This can be particularly useful for low power
+ * devices. If there is no use-case for this function (either power-down or
+ * reset) then provide NULL.
+ *
+ * reset: This function can get called if the device communication broke down.
+ * This functionality is particularly useful in case of SDIO type devices. It is
+ * possible to reset a dongle via sdio data interface, but it requires that
+ * this is fully functional. This function is chip/module specific and this
+ * function should return only after the complete reset has completed.

Subject: [PATCH 1221/1722] brcmfmac: obtain iftype for firmware-signal
 descriptor lookup

The function brcmf_fws_find_mac_desc() determines the descriptor
associated with a sk_buff for firmware-signalling. It needs the
interface type to do that. For this a helper function is added in
wl_cfg80211.c.

Subject: [PATCH 1228/1722] act_csum: fix possible use after free
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

tcf_csum_skb_nextlayer() / pskb_may_pull() can change skb->head, so we
must be careful not keeping pointers to previous headers.

Subject: [PATCH 1230/1722] ath5k: use more idiomatic tracing include style

Pretty much everywhere that uses a trace definition
header that's not in include/trace/events/ uses the
make system for the include path rather than putting
it into the sources, so do that in ath5k as well.

This came up during backporting work (where this is
required), but since all other drivers do it this
way upstream it seemed applicable.

Subject: [PATCH 1232/1722] tcp: GSO should be TSQ friendly

I noticed that TSQ (TCP Small queues) was less effective when TSO is
turned off, and GSO is on. If BQL is not enabled, TSQ has then no
effect.

It turns out the GSO engine frees the original gso_skb at the time the
fragments are generated and queued to the NIC.

We should instead call the tcp_wfree() destructor for the last fragment,
to keep the flow control as intended in TSQ. This effectively limits
the number of queued packets on qdisc + NIC layers.

Subject: [PATCH 1233/1722] ptp: dynamic allocation of PHC char devices

As network adapters supporting PTP are becoming more common, machines with
many NICs suddenly have many PHCs, too. The current limit of eight /dev/ptp*
char devices (and thus, 8 network interfaces with PHC) is insufficient. Let
the ptp driver allocate the char devices dynamically.

Tested with 28 PHCs, removing and re-adding some of them.

Thanks to Ben Hutchings for advice leading to simpler and cleaner patch.

Subject: [PATCH 1239/1722] gianfar: Use netdev_<level> when possible

Use a more current logging style.

Convert pr_<level> to netdev_<level> when a struct net_device is
available.  Add pr_fmt and neaten other formats too.

Subject: [PATCH 1240/1722] ucc_geth: Convert ugeth_<level> to pr_<level>

Remove unnecessary macros that duplicate generic
kernel functions.

When a struct net_device is available:

Convert printks to netdev_<level>
Convert netif_msg_<foo> and ugeth_<level> to netif_<level>

Add pr_fmt.  Standardize on newlines at end of format.
Remove some duplicated newlines from output.
Coalesce formats.

Subject: [PATCH 1241/1722] vxlan: use htonl when snooping for loopback address

Currently "bridge fdb show dev vxlan0" lists loopback address as
"1.0.0.127". Using htonl(INADDR_LOOPBACK) rather than passing it
directly to vxlan_snoop fixes the problem.

Subject: [PATCH 1242/1722] net: sock: make sock_tx_timestamp void

Currently, sock_tx_timestamp() always returns 0. The comment that
describes the sock_tx_timestamp() function wrongly says that it
returns an error when an invalid argument is passed (from commit
20d4947353be, ``net: socket infrastructure for SO_TIMESTAMPING'').
Make the function void, so that we can also remove all the unneeded
if conditions that check for such a _non-existant_ error case in the
output path.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Commit 10b96f7306e5 (``tcp_memcontrol: remove a redundant statement
in tcp_destroy_cgroup()'') says ``We read the value but make no use
of it.'', but forgot to remove the variable declaration as well. This
was a follow-up commit of 3f1346193 (``memcg: decrement static keys
at real destroy time'') that removed the read of variable 'val'.

This fixes therefore:

Subject: [PATCH 1244/1722] vxlan: don't bypass encapsulation for multi- and
 broadcasts

The multicast and broadcast packets may have RTCF_LOCAL set in rt_flags
and therefore will be sent out bypassing encapsulation. This breaks
delivery of packets sent to the vxlan multicast group.
Disabling encapsulation bypass for multicasts and broadcasts fixes the
issue.

Subject: [PATCH 1247/1722] net: sctp: remove sctp_ep_common struct member
 'malloced'

There is actually no need to keep this member in the structure, because
after init it's always 1 anyway, thus always kfree called. This seems to
be an ancient leftover from the very initial implementation from 2.5
times. Only in case the initialization of an association fails, we leave
base.malloced as 0, but we nevertheless kfree it in the error path in
sctp_association_new().

Subject: [PATCH 1248/1722] net: sctp: minor: make sctp_ep_common's member
 'dead' a bool

Since dead only holds two states (0,1), make it a bool instead
of a 'char', which is more appropriate for its purpose.

Subject: [PATCH 1249/1722] net: add dev_uc_sync_multiple() and
 dev_mc_sync_multiple() api

The current implementation of dev_uc_sync/unsync() assumes that there is
a strict 1-to-1 relationship between the source and destination of the sync.
In other words, once an address has been synced to a destination device, it
will not be synced to any other device through the sync API.
However, there are some virtual devices that aggreate a number of lower
devices and need to sync addresses to all of them.  The current
API falls short there.

This patch introduces a new dev_uc_sync_multiple() api that can be called
in the above circumstances and allows sync to work for every invocation.

Subject: [PATCH 1250/1722] team: Use new sync_multiple api to sync devices
 adressess.

Team drivers attempts to sync addresses to each of the port
devices; however, the current api doesn't really perform the sync
for any device after the first one.  Switch to using the new api
that will actually sync the addresses to all ports.

Date: Mon, 15 Apr 2013 13:23:03 -0700
Subject: [PATCH 1251/1722] openvswitch: Simplify datapath locking.

Currently OVS uses combination of genl and rtnl lock to protect
datapath state.  This was done due to networking stack locking.
But this has complicated locking and there are few lock ordering
issues with new tunneling protocols.
Following patch simplifies locking by introducing new ovs mutex
and now this lock is used to protect entire ovs state.

Subject: [PATCH 1252/1722] openvswitch: Use generic struct pcpu_tstats.

Rather than defining ovs specific stats struct (vport_percpu_stats),
we can use existing pcpu_tstats to achieve exactly same functionality.

Subject: [PATCH 1253/1722] NFC: mei: Add a common mei bus API for NFC drivers

This isolates the common code that is required to use an mei bus nfc
device from an NFC HCI drivers. This prepares for future drivers for
NFC chips connected behind an Intel Management Engine controller.
The microread_mei HCI driver is also modified to use that common code.

From: Oliver Hartkopp <socketcan@hartkopp.net>
Date: Sat, 13 Apr 2013 21:35:49 +0200
Subject: [PATCH 1255/1722] can: sja1000: use common prefix for all sja1000
 defines

This is a follow up patch to:

    f901b6b can: sja1000: fix define conflict on SH

That patch fixed a define conflict between the SH architecture and the sja1000
driver, by addind a prefix to one macro only. This patch consistently renames
the prefix of the SJA1000 controller registers from "REG_" to "SJA1000_".

Subject: [PATCH 1256/1722] wireless: regulatory: fix channel disabling race
 condition

When a full scan 2.4 and 5 GHz scan is scheduled, but then the 2.4 GHz
part of the scan disables a 5.2 GHz channel due to, e.g. receiving
country or frequency information, that 5.2 GHz channel might already
be in the list of channels to scan next. Then, when the driver checks
if it should do a passive scan, that will return false and attempt an
active scan. This is not only wrong but can also lead to the iwlwifi
device firmware crashing since it checks regulatory as well.

Fix this by not setting the channel flags to just disabled but rather
OR'ing in the disabled flag. That way, even if the race happens, the
channel will be scanned passively which is still (mostly) correct.

have to set it to 0 anyway.

Subject: [PATCH 1258/1722] mac80211: unify CSA action frame/beacon processing

CSA action frame content should be processed as variable IEs
rather than fixed to make it extensible. Unify the code and
process them just like CSA in beacons to make it easier to
extend for HT/VHT.

Subject: [PATCH 1259/1722] cfg80211: add ieee80211_operating_class_to_band

This function converts a (global only!) operating
class to an internal band identifier. This will
be needed for extended channel switch support.

Subject: [PATCH 1260/1722] mac80211: support extended channel switch

Support extended channel switch when the operating
class is one of the global operating classes as
defined in Annex E of 802.11-2012. If it isn't,
disconnect from the AP instead.

Subject: [PATCH 1261/1722] mac80211: support secondary channel offset in CSA

Add support for the secondary channel offset IE in channel
switch announcements. This is necessary for proper handling
of CSA on HT access points.

For this to work it is also necessary to convert everything
here to use chandef structs instead of just channels. The
driver updates aren't really correct though. In particular,
the TI wl18xx driver update can't possibly be right since
it just ignores the new channel width for lack of firmware
API.

Subject: [PATCH 1262/1722] mac80211: handle extended channel switch
 announcement

Handle the (public) extended channel switch announcement
action frames. Parts of the data in these frames isn't
really in IEs, but put it into the elems struct anyway
to simplify the handling.

Subject: [PATCH 1263/1722] mac80211: parse VHT channel switch IEs

VHT introduces multiple IEs that need to be parsed for a
wide bandwidth channel switch. Two are (currently) needed
in mac80211:
 * wide bandwidth channel switch element
 * channel switch wrapper element

The former is contained in the latter for beacons and probe
responses, but not for the spectrum management action frames
so the IE parser needs a new argument to differentiate them.

Subject: [PATCH 1264/1722] mac80211: handle wide bandwidth channel switch

Parse and react to the wide bandwidth channel switch element
in beacons/action frames. Finding the element was done in a
previous patch (it has different positions in beacons/action
frames), now handle it. If there's something wrong with it
simply disconnect.

Subject: [PATCH 1265/1722] mac80211: remove warning from ieee80211_beacon_loss

Currently, mac80211 assumes that connection monitor offload
for BSS station implies that the device:
- sends periodic keep alive packets to associated AP
- monitors missed beacons
- actively probes the AP in case of missed beacons

In case of poor connection conditions it expects the function
ieee80211_connection_loss() to be called by driver. However,
some devices implement connection monitor offload excluding
active AP probing.

To allow them to call ieee80211_beacon_loss() cleanly, remove
the warning there and thus allow them to use mac80211 for the
AP probing even if connection monitor offload is supported.

first_antenna is supposed to return the first antenna as a
0-based bitmap: ANT_A is BIT(0), ANT_B is BIT(1), etc...
Since ffs is 1 based (ffs(BIT(0)) = 1), then we had an
off-by-one bug:
BIT(ffs(ANT_A)) = BIT(ffs(BIT(0))) = BIT(1) = ANT_B.
So what we really want is:
BIT(ffs(ANT_A) - 1) = BIT(ffs(BIT(0)) - 1) = BIT(0) = ANT_A.

Subject: [PATCH 1270/1722] mac80211: adjust initial chandefs assignments in
 ieee80211_register_hw

I noticed that monitor interfaces by default would start on 5GHz
while STA/AP ones would start 2GHZ - It stems from the fact that
ieee80211_register_hw unnecessarily adjusts the local->monitor_chandef
for each band.

This avoids this and while at it uses a single dflt_chandef to initialize
in one go local->{hw.conf.chandef,_oper_chandef,monitor_chandef}

Subject: [PATCH 1271/1722] mac80211: VHT off-by-one NSS

The number of VHT spatial streams (NSS) is found in:
- s8 ieee80211_tx_rate.rate.idx[6:4] (tx - filled by rate control)
- u8 ieee80211_rx_status.vht_nss     (rx - filled by driver)
Tx discriminates valid rates indexes with the sign bit and encodes NSS
starting from 0 to 7 (note this matches some hw encodings e.g IWLMVM).
Rx does not have the same constraints, and encodes NSS starting from 1
to 8 (note this matches what wireshark expects in the radiotap header).

To handle ieee80211_tx_rate.rate.idx[6:4] ieee80211_rate_set_vht() and
ieee80211_rate_get_vht_nss() assume their nss parameter and return value
respectively runs from 0 to 7.
ATM, there are only 2 users of these: cfg.c:sta_set_rate_info_t() and
iwlwifi/mvm/tx.c:iwl_mvm_hwrate_to_tx_control(), but both assume nss
runs from 1 to 8.
This patch fixes this inconsistency by making ieee80211_rate_set_vht()
and ieee80211_rate_get_vht_nss() handle an nss running from 1 to 8.

Subject: [PATCH 1279/1722] at86rf230: change irq handling to prevent lockups
 with edge type irq

Implemented separate irq handling for edge and level type interrupt
configuration. For edge type interrupts calls to disable_irq_nosync()
and enable_irq() are removed. The at86rf230 resets the irq line only
after the irq status register is read. Disabling the irq can lock the
driver in situations where a irq is set by the radio while the driver
is still reading the frame buffer.

With irq_type configuration set to 0 the original behavior is
preserverd.

Additional the irq filter register is set to filter out all unused
interrupts and the irq status register is read in the probe
function to clear the irq line.

Subject: [PATCH 1280/1722] neighbour: Convert NEIGH_PRINTK to neigh_dbg

Update debugging messages to a more current style.

Emit these debugging messages at KERN_DEBUG instead
of KERN_DEFAULT.

Add and use neigh_dbg(level, fmt, ...) macro
Add dynamic_debug capability via pr_debug
Convert embedded function names to "%s: ", __func__

the work has been scheduled from interrupt, and not been
cancelled when the driver is unloaded, which doesn't remove
the work item from the global workqueue. call the
cancel_work_sync when the driver is removed (rmmod'ed).

Subject: [PATCH 1282/1722] sctp: Add buffer utilization fields to
 /proc/net/sctp/assocs

sctp: Add buffer utilization fields to /proc/net/sctp/assocs

This patch adds the following fields to /proc/net/sctp/assocs output:

	- sk->sk_wmem_alloc as "wmema"	(transmit queue bytes committed)
	- sk->sk_wmem_queued as "wmemq"	(persistent queue size)
	- sk->sk_sndbuf as "sndbuf"	(size of send buffer in bytes)
	- sk->sk_rcvbuf as "rcvbuf"	(size of receive buffer in bytes)

When small DATA chunks containing 136 bytes data are sent the TX_QUEUE
(assoc->sndbuf_used) reaches a maximum of 40.9% of sk_sndbuf value when
peer.rwnd = 0. This was diagnosed from sk_wmem_alloc value reaching maximum
value of sk_sndbuf.

TX_QUEUE (assoc->sndbuf_used), sk_wmem_alloc and sk_wmem_queued values are
incremented in sctp_set_owner_w() for outgoing data chunks. Having access to
the above values in /proc/net/sctp/assocs will provide a better understanding
of SCTP buffer management.

With patch applied, example output when peer.rwnd = 0

 packet headers

There is no need to add a dozen unions each time at the start
of the function. So, do this once and use it instead. Thus, we
can remove some duplicate code and make it more readable.

Subject: [PATCH 1284/1722] vxlan: Allow setting destination to unicast
 address.

This patch allows setting VXLAN destination to unicast address.
It allows that VXLAN can be used as peer-to-peer tunnel without
multicast.

v4: generalize struct vxlan_dev, "gaddr" is replaced with vxlan_rdst.
    "GROUP" attribute is replaced with "REMOTE".
    they are based by David Stevens's comments.

v3: move a new attribute REMOTE into the last of an enum list
    based by Stephen Hemminger's comments.

v2: use a new attribute REMOTE instead of GROUP based by
    Cong Wang's comments.

Subject: [PATCH 1285/1722] pch_gbe: minor: report the actual error on MTU
 change

If we can't _up() after changing the MTU, report the actual error instead
of -ENOMEM. It can be really misleading cause pch_gbe is usually used in
scenarios where the memory amount is really small, and thus hiding the
real cause.

Subject: [PATCH 1287/1722] mac80211: fix and optimize MCS mask handling

Currently the code always copies the configured MCS mask (even if it is
set to default), but only uses it if legacy rates were also masked out.
Fix this by adding a flag that tracks whether the configured MCS mask is
set to default or not.
Optimize the code further by storing a pointer to the configured rate
mask in txrc instead of using memcpy.

Subject: [PATCH 1288/1722] mac80211: fix CTS protection handling

The rates[0] CTS and RTS flags are only set after rate control has been
called, so minstrel cannot use them to for setting the number of
retries. This patch adds two new flags to explicitly indicate RTS/CTS use.

commit 7b7a2bbb690 (atl1: Remove unneeded PM_OPS definitions) removed the

So only call atl1_suspend() when CONFIG_PM_SLEEP is defined and fix the

Subject: [PATCH 1290/1722] Bluetooth: remove unneeded
 hci_conn_hold/put_device()

hci_conn_hold/put_device() is used to control when hci_conn->dev is no
longer needed and can be deleted from the system. Lets first look how they
are currently used throughout the code (excluding HIDP!).

All code that uses hci_conn_hold_device() looks like this:
    ...
    hci_conn_hold_device();
    hci_conn_add_sysfs();
    ...
On the other side, hci_conn_put_device() is exclusively used in
hci_conn_del().

So, considering that hci_conn_del() must not be called twice (which would
fail horribly), we know that hci_conn_put_device() is only called _once_
(which is in hci_conn_del()).
On the other hand, hci_conn_add_sysfs() must not be called twice, either
(it would call device_add twice, which breaks the device, see
drivers/base/core.c). So we know that hci_conn_hold_device() is also
called only once (it's only called directly before hci_conn_add_sysfs()).

So hold and put are known to be called only once. That means we can safely
remove them and directly call hci_conn_del_sysfs() in hci_conn_del().

But there is one issue left: HIDP also uses hci_conn_hold/put_device().
However, this case can be ignored and simply removed as it is totally
broken. The issue is, the only thing HIDP delays with
hci_conn_hold_device() is the removal of the hci_conn->dev from sysfs.
But, the hci_conn device has no mechanism to get notified when its own
parent (hci_dev) gets removed from sysfs. hci_dev_hold/put() does _not_
control when it is removed but only when the device object is created
and destroyed.
And hci_dev calls hci_conn_flush_*() when it removes itself from sysfs,
which itself causes hci_conn_del() to be called, but it does _not_ cause
hci_conn_del_sysfs() to be called, which is wrong.

Hence, we fix it to call hci_conn_del_sysfs() in hci_conn_del(). This
guarantees that a hci_conn object is removed from sysfs _before_ its
parent hci_dev is removed.

The changes to HIDP look scary, wrong and broken. However, if you look at
the HIDP session management, you will notice they're already broken in the
exact _same_ way (ever tried "unplugging" HIDP devices? Breaks _all_ the
time).
So this patch only makes HIDP look _scary_ and _obviously broken_. It does
not break HIDP itself, it already is!

See later patches in this series which fix HIDP to use proper
session-management.

Subject: [PATCH 1291/1722] Bluetooth: introduce hci_conn ref-counting

We currently do not allow using hci_conn from outside of HCI-core.
However, several other users could make great use of it. This includes
HIDP, rfcomm and all other sub-protocols that rely on an active
connection.

Hence, we now introduce hci_conn ref-counting. We currently never call
get_device(). put_device() is exclusively used in hci_conn_del_sysfs().
Hence, we currently never have a greater device-refcnt than 1.
Therefore, it is safe to move the put_device() call from
hci_conn_del_sysfs() to hci_conn_del() (it's the only caller). In fact,
this even fixes a "use-after-free" bug as we access hci_conn after calling
hci_conn_del_sysfs() in hci_conn_del().

From now on we can add references to hci_conn objects in other layers
(like l2cap_sock, HIDP, rfcomm, ...) and grab a reference via
hci_conn_get(). This does _not_ guarantee, that the connection is still
alive. But, this isn't what we want. We can simply lock the hci_conn
device and use "device_is_registered(hci_conn->dev)" to test that.
However, this is hardly necessary as outside users should never rely on
the HCI connection to be alive, anyway. Instead, they should solely rely
on the device-object to be available.
But if sub-devices want the hci_conn object as sysfs parent, they need to
be notified when the connection drops. This will be introduced in later
patches with l2cap_users.

Subject: [PATCH 1292/1722] Bluetooth: hidp: remove unused session->state field

This field is always BT_CONNECTED. Remove it and set it to BT_CONNECTED in
hidp_copy_session() unconditionally.

Also note that this field is totally bogus. Userspace can query an
hidp-session for its state. However, whenever user-space queries us, this
field should be BT_CONNECTED. If it wasn't BT_CONNECTED, then we would be
currently cleaning up the session and the session itself would exit in the
next few milliseconds. Hence, there is no reason to let user-space know
that the session will exit now if they cannot make _any_ use of that.

Thus, remove the field and let user-space think that a session is always
BT_CONNECTED as long as they can query it.

Subject: [PATCH 1293/1722] Bluetooth: hidp: test "terminate" before sleeping

The "terminate" flag is guaranteed to be set before the session terminates
and the handlers are woken up. Hence, we need to add it to the
sleep-condition.

Note that testing the flags is not enough as nothing prevents us from
setting the flags again after the session-handler terminated.

Subject: [PATCH 1296/1722] Bluetooth: l2cap: introduce l2cap_conn ref-counting

If we want to use l2cap_conn outside of l2cap_core.c, we need refcounting
for these objects. Otherwise, we cannot synchronize l2cap locks with
outside locks and end up with deadlocks.

Hence, introduce ref-counting for l2cap_conn objects. This doesn't affect
l2cap internals at all, as they use a direct synchronization.
We also keep a reference to the parent hci_conn for locking purposes as
l2cap_conn depends on this. This doesn't affect the connection itself but
only the lifetime of the (dead) object.

Subject: [PATCH 1297/1722] Bluetooth: l2cap: add l2cap_user sub-modules

Several sub-modules like HIDP, rfcomm, ... need to track l2cap
connections. The l2cap_conn->hcon->dev object is used as parent for sysfs
devices so the sub-modules need to be notified when the hci_conn object is
removed from sysfs.

As submodules normally use the l2cap layer, the l2cap_user objects are
registered there instead of on the underlying hci_conn object. This avoids
any direct dependency on the HCI layer and lets the l2cap core handle any
specifics.

This patch introduces l2cap_user objects which contain a "probe" and
"remove" callback. You can register them on any l2cap_conn object and if
it is active, the "probe" callback will get called. Otherwise, an error is
returned.

The l2cap_conn object will call your "remove" callback directly before it
is removed from user-space. This allows you to remove your submodules
_before_ the parent l2cap_conn and hci_conn object is removed.

At any time you can asynchronously unregister your l2cap_user object if
your submodule vanishes before the l2cap_conn object does.

There is no way around l2cap_user. If we want wire-protocols in the
kernel, we always want the hci_conn object as parent in the sysfs tree. We
cannot use a channel here since we might need multiple channels for a
single protocol.
But the problem is, we _must_ get notified when an l2cap_conn object is
removed. We cannot use reference-counting for object-removal! This is not
how it works. If a hardware is removed, we should immediately remove the
object from sysfs. Any other behavior would be inconsistent with the rest
of the system. Also note that device_del() might sleep, but it doesn't
wait for user-space or block very long. It only _unlinks_ the object from
sysfs and the whole device-tree. Everything else is handled by ref-counts!
This is exactly what the other sub-modules must do: unlink their devices
when the "remove" l2cap_user callback is called. They should not do any
cleanup or synchronous shutdowns.

Subject: [PATCH 1298/1722] Bluetooth: hidp: add new session-management helpers

This is a rewrite of the HIDP session management. It implements HIDP as an
l2cap_user sub-module so we get proper notification when the underlying
connection goes away.

The helpers are not yet used but only added in this commit. The old
session management is still used and will be removed in a following patch.

The old session-management was flawed. Hotplugging is horribly broken and
we have no way of getting notified when the underlying connection goes
down. The whole idea of removing the HID/input sub-devices from within the
session itself is broken and suffers from major dead-locks. We never can
guarantee that the session can unregister itself as long as we use
synchronous shutdowns. This can only work with asynchronous shutdowns.
However, in this case we _must_ be able to unregister the session from the
outside as otherwise the l2cap_conn object might be unlinked before we
are.

The new session-management is based on l2cap_user. There is only one
way how to add a session and how to delete a session: "probe" and "remove"
callbacks from l2cap_user.
This guarantees that the session can be registered and unregistered at
_any_ time without any synchronous shutdown.
On the other hand, much work has been put into proper session-refcounting.
We can unregister/unlink the session only if we can guarantee that it will
stay alive. But for asynchronous shutdowns we never know when the last
user goes away so we must use proper ref-counting.

The old ->conn field has been renamed to ->hconn so we can reuse ->conn in
the new session management. No other existing HIDP code is modified.

Subject: [PATCH 1299/1722] Bluetooth: hidp: remove old session-management

We have the full new session-management now available so lets switch over
and remove all the old code. Few semantics changed, so we need to adjust
the sock.c callers a bit. But this mostly simplifies the logic.

Subject: [PATCH 1300/1722] Bluetooth: hidp: handle kernel_sendmsg() errors
 correctly

We shouldn't push back the skbs if kernel_sendmsg() fails. Instead, we
terminate the connection and drop the skb. Only on EAGAIN we push it back
and return.
l2cap doesn't return EAGAIN, yet, but this guarantees we're safe if it
will at some time in the future.

Subject: [PATCH 1301/1722] Bluetooth: hidp: merge
 hidp_process_{ctrl,intr}_transmit()

Both hidp_process_ctrl_transmit() and hidp_process_intr_transmit() are
exactly the same apart from the transmit-queue and socket pointers.
Therefore, pass them as argument and merge both functions into one so we
avoid 25 lines of code-duplication.

Subject: [PATCH 1302/1722] Bluetooth: hidp: merge 'send' functions into
 hidp_send_message()

We handle skb buffers all over the place, even though we have
hidp_send_*_message() helpers. This creates a more generic
hidp_send_message() helper and uses it instead of dealing with transmit
queues directly everywhere.

Subject: [PATCH 1303/1722] Bluetooth: hidp: don't send boot-protocol messages
 as HID-reports

If a device is registered as HID device, it is always in Report-Mode.
Therefore, we must not send Boot-Protocol messages on
hidinput_input_event() callbacks. This confuses devices and may cause
disconnects on protocol errors.

We disable the hidinput_input_event() callback for now. We can implement
it properly later, but lets first fix the current code by disabling it.

Subject: [PATCH 1304/1722] Bluetooth: hidp: fix sending output reports on intr
 channel

According to the specifications, data output reports must be sent on the
interrupt channel. See also usbhid implementation.
Sending these reports on the control channel breaks newer Wii Remotes.

Note that this will make output reports asynchronous. However, that's how
hid_output_raw_report() is supposed to work with HID_OUTPUT_REPORT as
report type. There are no responses to output reports.

Subject: [PATCH 1305/1722] mac80211: fix station entry leak/warning while
 suspending

Since Stanislaw's patches, when suspending while connected,
cfg80211 will disconnect. This causes the AP station to be
removed, which uses call_rcu() to clean up. Due to needing
process context, this queues a work struct on the mac80211
workqueue. This will warn and fail when already suspended,
which can happen if the rcu call doesn't happen quickly.

To fix this, replace the synchronize_net() which is really
just synchronize_rcu_expedited() with rcu_barrier(), which
unlike synchronize_rcu() waits until RCU callback have run
and thus avoids this issue.

In theory, this can even happen without Stanislaw's change
to disconnect on suspend since userspace might disconnect
just before suspending, though then it's unlikely that the
call_rcu() will be delayed long enough.

Subject: [PATCH 1309/1722] net: sctp: sctp_inq: remove dead code

sctp_inq is never kmalloced, since it's integrated into sctp_ep_common
and only initialized from eps and assocs. Therefore, remove the dead
code from there.

sctp_outq is embedded into sctp_association, and thus never
kmalloced in any way. Also, malloced is always 0, thus kfree()
is never called. Therefore, remove that dead piece of code.

Some network protocols, like InfiniBand, don't have a fixed broadcast
address but one that depends on the configuration. Move the bcast_addr
to struct tipc_bearer and initialize it with the broadcast address of
the network device when the bearer is enabled.

Subject: [PATCH 1318/1722] tipc: set skb->protocol in eth_media packet
 transmission

The skb->protocol field is used by packet classifiers and for AF_PACKET
cooked format, TIPC needs to set it properly.

Fixes packet classification and ethertype of 0x0000 in cooked captures:

Out 20:c9:d0:43:12:d9 ethertype Unknown (0x0000), length 56:
	0x0000:  5b50 0028 0000 30d4 0100 1000 0100 1001  [P.(..0.........
	0x0010:  0000 03e8 0000 0001 20c9 d043 12d9 0000  ...........C....
	0x0020:  0000 0000 0000 0000                      ........

Subject: [PATCH 1319/1722] tipc: add InfiniBand media type

Add InfiniBand media type based on the ethernet media type.

The only real difference is that in case of InfiniBand, we need the entire
20 bytes of space reserved for media addresses, so the TIPC media type ID is
not explicitly stored in the packet payload.

Sample output of tipc-config:

# tipc-config -v -addr -netid -nt=all -p -m -b -n -ls

Subject: [PATCH 1320/1722] IPoIB: add support for TIPC protocol

Support TIPC in the IPoIB driver. Since IPoIB now keeps track of its own
neighbour entries and doesn't require the packet to have a dst_entry
anymore, the only necessary changes are to:

- not drop multicast TIPC packets because of the unknown ethernet type
- handle unicast TIPC packets similar to IPv4/IPv6 unicast packets

in ipoib_start_xmit().

An alternative would be to remove all ethertype limitations since they're
not necessary anymore, all TIPC needs to know about is ARP and RARP since
it wants to always perform "path find", even if a path is already known.

Subject: [PATCH 1321/1722] Bluetooth: Fix incorrect SSP mode bit for non SSP
 devices

Some faulty non SSP devices send extended inquiry response
during device discovery which is a violation of 2.1 specification.
So for these devices we set SSP bit during acl connection
initiation thinking that it is an SSP device. But for these
devices, in remote host features event SSP supported bit
will be off. But we are not clearing the SSP bit in that case
and eventually SSP bit in conn flag will be incorrectly set for
these devices.

The software which has caused this issue is MecApp
http://www.mecel.se/products/bluetooth/downloads/MecApp_download

This patch does a workaround by clearing the SSP bit if it is
not supported in remote host features event

Subject: [PATCH 1323/1722] Bluetooth: Track feature pages in a single table

The local and remote features are organized by page number. Page 0
are the LMP features, page 1 the host features, and any pages beyond 1
features that future core specification versions may define. So far
we've only had the first two pages and two separate variables has been
convenient enough, however with the introduction of Core Specification
Addendum 4 there are features defined on page 2.

Instead of requiring the addition of a new variable each time a new page
number is defined, this patch refactors the code to use a single table
for the features. The patch needs to update both the hci_dev and
hci_conn structures since there are macros that depend on the features
being represented in the same way in both of them.

Subject: [PATCH 1324/1722] Bluetooth: Add reading of all local feature pages

With the introduction of CSA4 there is now also a features page number 2
available. This patch increments the maximum supported page number to 2
and adds code for reading all available pages (as long as we have
support for them - indicated by HCI_MAX_PAGES).

Subject: [PATCH 1327/1722] Bluetooth: Add macros for filter duplicates values

This patch adds macros for filter_duplicates parameter values from
HCI LE Set Scan Enable command. It also fixes le_scan_enable_req
function so it uses the LE_SCAN_FILTER_DUP_ENABLE macro instead of
a magic number.

The LE_SCAN_FILTER_DUP_DISABLE was also defined since it will be
required to properly support the GAP Observer Role.

Subject: [PATCH 1328/1722] Bluetooth: Rename LE_SCANNING_* macros

This patch renames LE_SCANNING_ENABLED and LE_SCANNING_DISABLED
macros to LE_SCAN_ENABLE and LE_SCAN_DISABLE in order to keep
the same prefix others LE scan macros have.

It also fixes le_scan_enable_req function so it uses the LE_SCAN_
ENABLE macro instead of a magic number.

Subject: [PATCH 1329/1722] ixgbe: Mask off check of frag_off as we only want
 fragment offset

We were incorrectly checking the entire frag_off field when we only wanted the
fragment offset.  As a result we were not pulling in TCP headers when the DNF
flag was set.

To correct that we will now check for frag off using the IP_OFFSET mask.

just drop the check and always compare the descriptors to the maximum size
supported.

Subject: [PATCH 1334/1722] ixgbe: enable devices with internal switch to read
 pci parent

This patch modifies the driver to enable certain devices, which have an internal
switch, to read data from the physical slot rather than reading data from the
internal switch. The internal switch will always report the same PCI width and
speed, which is not useful compared to knowing the width and speed of the slot
the physical card is plugged into.

Subject: [PATCH 1335/1722] ixgbe: fix MNG FW support when adapter not up

We were only turning the laser on when the adapter was up.  This
causes issues for those who wanted to access the MNG FW while the
port was in a down state.  This patch makes sure the laser is turned
on in probe and remain up even after the port is brought down.

Subject: [PATCH 1336/1722] ixgbe: Fix 1G link WoL

We reset during the shutdown path which will reset AUTOC register.  This
would change LMS to 10G.  If we were currently linked at 1G we will lose
link, which is a bad thing if we wanted WoL to work.  For the fix I needed
to know if WoL is supported so I created a new bool in the ixgbe_hw struct.
If this is set we will not allow the reset to change the current LMS value
in AUTOC.

Subject: [PATCH 1340/1722] iwlwifi: mvm: remove usage of power_save module
 parameter

Make power management in MVM driver enabled by default and
remove using the power_save module parameter. Rely only on
the power_scheme parameter to decide if power management
should be used.

When the stations are being restored because of unassoc
RXON, the LQ cmd may not have been initialized because it
is initialized only after association.
Sending zeroed LQ_CMD makes the fw unhappy: it raises
SYSASSERT_2078.

Subject: [PATCH 1344/1722] netfilter: add my copyright statements

Add copyright statements to all netfilter files which have had significant
changes done by myself in the past.

Some notes:

- nf_conntrack_ecache.c was incorrectly attributed to Rusty and Netfilter
  Core Team when it got split out of nf_conntrack_core.c. The copyrights
  even state a date which lies six years before it was written. It was
  written in 2005 by Harald and myself.

- net/ipv{4,6}/netfilter.c, net/netfitler/nf_queue.c were missing copyright
  statements. I've added the copyright statement from net/netfilter/core.c,
  where this code originated

- for nf_conntrack_proto_tcp.c I've also added Jozsef, since I didn't want
  it to give the wrong impression

Subject: [PATCH 1346/1722] tcp: introduce TCPSpuriousRtxHostQueues SNMP
 counter

Host queues (Qdisc + NIC) can hold packets so long that TCP can
eventually retransmit a packet before the first transmit even left
the host.

Its not clear right now if we could avoid this in the first place :

- We could arm RTO timer not at the time we enqueue packets, but
  at the time we TX complete them (tcp_wfree())

- Cancel the sending of the new copy of the packet if prior one
  is still in queue.

This patch adds instrumentation so that we can at least see how
often this problem happens.

TCPSpuriousRtxHostQueues SNMP counter is incremented every time
we detect the fast clone is not yet freed in tcp_transmit_skb()

Subject: [PATCH 1347/1722] ixgbe: in shutdown, do netif_running() under
 rtnl_lock

During shutdown it's possible for __dev_close() (which holds
rtnl_lock) to clear the __LINK_STATE_START bit, and for ixgbe
to then read that bit (without holding rtnl_lock), and then
not fail to free irqs, etc. The result is a crash like this:

Subject: [PATCH 1351/1722] mac80211: fix P2P-Device management frame RX

There's an issue in receiving broadcast management frames
on P2P Device virtual interfaces, such frames have the RX
flag IEEE80211_RX_RA_MATCH cleared and are thus dropped
in ieee80211_rx_h_mgmt_check(). They should be let through
to make it to ieee80211_rx_h_userspace_mgmt() and then to
userspace.

Subject: [PATCH 1354/1722] nl80211: allow using wdev identifiers to get scan
 results

Most dump callbacks, including the scan results one, use
the netdev to identify what to do, which is incorrect for
the P2P_DEVICE support, it needs to be able to get the
scan result from the wdev. Change all dumps to unify the
code, but ones other than scan don't really support being
executed on a wdev that has no netdev.

We were incorrectly checking the entire frag_off field when we only wanted the

flag was set.

To correct that we will now check for frag off using the IP_OFFSET mask.

Subject: [PATCH 1360/1722] igb: Use rx/tx_itr_setting when setting up initial
 value of itr

It turns out that the InterruptThrottleRate module parameter was only
having the effect of locking the ITR at the starting ITR value. This was
because the values stored in rx_itr_setting and tx_itr_setting were being
ignored when configuring the initial itr_val of the q_vector.

Subject: [PATCH 1366/1722] Bluetooth: Fix HCI command send functions to use
 const specifier

All HCI command send functions that take a pointer to the command
parameters do not need to modify the content in any way (they merely
copy the data to an skb). Therefore, the parameter type should be
declared const. This also allows passing already const parameters to
these APIs which previously would have generated a compiler warning.

Subject: [PATCH 1367/1722] net: vlan: rename NETIF_F_HW_VLAN_* feature flags
 to NETIF_F_HW_VLAN_CTAG_*

Rename the hardware VLAN acceleration features to include "CTAG" to indicate
that they only support CTAGs. Follow up patches will introduce 802.1ad
server provider tagging (STAGs) and require the distinction for hardware not
supporting acclerating both.

From 80d5c3689b886308247da295a228a54df49a44f6 Mon Sep 17 00:00:00 2001
From: Patrick McHardy <kaber@trash.net>
Date: Fri, 19 Apr 2013 02:04:28 +0000
Subject: [PATCH 1368/1722] net: vlan: prepare for 802.1ad VLAN filtering
 offload

Change the rx_{add,kill}_vid callbacks to take a protocol argument in
preparation of 802.1ad support. The protocol argument used so far is
always htons(ETH_P_8021Q).

From 1fd9b1fc310314911f66d2f14a8e4f0ef37bf47b Mon Sep 17 00:00:00 2001
From: Patrick McHardy <kaber@trash.net>
Date: Fri, 19 Apr 2013 02:04:29 +0000
Subject: [PATCH 1369/1722] net: vlan: prepare for 802.1ad support

Make the encapsulation protocol value a property of VLAN devices and change
the device lookup functions to take the protocol value into account.

From 86a9bad3ab6b6f858fd4443b48738cabbb6d094c Mon Sep 17 00:00:00 2001
From: Patrick McHardy <kaber@trash.net>
Date: Fri, 19 Apr 2013 02:04:30 +0000
Subject: [PATCH 1370/1722] net: vlan: add protocol argument to packet tagging
 functions

Add a protocol argument to the VLAN packet tagging functions. In case of HW
tagging, we need that protocol available in the ndo_start_xmit functions,
so it is stored in a new field in the skb. The new field fits into a hole
(on 64 bit) and doesn't increase the sks's size.

From 8ad227ff89a7e6f05d07cd0acfd95ed3a24450ca Mon Sep 17 00:00:00 2001
From: Patrick McHardy <kaber@trash.net>
Date: Fri, 19 Apr 2013 02:04:31 +0000
Subject: [PATCH 1371/1722] net: vlan: add 802.1ad support

Add support for 802.1ad VLAN devices. This mainly consists of checking for
ETH_P_8021AD in addition to ETH_P_8021Q in a couple of places and check
offloading capabilities based on the used protocol.

Configuration is done using "ip link":

# ip link add link eth0 eth0.1000 \
	type vlan proto 802.1ad id 1000
# ip link add link eth0.1000 eth0.1000.1000 \
	type vlan proto 802.1q id 1000

52:54:00:12:34:56 > 92:b1:54:28:e4:8c, ethertype 802.1Q (0x8100), length 106: vlan 1000, p 0, ethertype 802.1Q, vlan 1000, p 0, ethertype IPv4, (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto ICMP (1), length 84)
    20.1.0.2 > 20.1.0.1: ICMP echo request, id 3003, seq 8, length 64
92:b1:54:28:e4:8c > 52:54:00:12:34:56, ethertype 802.1Q-QinQ (0x88a8), length 106: vlan 1000, p 0, ethertype 802.1Q, vlan 1000, p 0, ethertype IPv4, (tos 0x0, ttl 64, id 47944, offset 0, flags [none], proto ICMP (1), length 84)
    20.1.0.1 > 20.1.0.2: ICMP echo reply, id 3003, seq 8, length 64

Subject: [PATCH 1374/1722] netlink: rename ssk to sk in struct
 netlink_skb_params

Memory mapped netlink needs to store the receiving userspace socket
when sending from the kernel to userspace. Rename 'ssk' to 'sk' to
avoid confusion.

Subject: [PATCH 1375/1722] net: add function to allocate sk_buff head without
 data area

Add a function to allocate a sk_buff head without any data. This will
be used by memory mapped netlink to attach data from the mmaped area
to the skb.

Additionally change skb_release_all() to check whether the skb has a
data area to allow the skb destructor to clear the data pointer in case
only a head has been allocated.

Subject: [PATCH 1376/1722] netlink: don't orphan skb in netlink_trim()

Netlink doesn't account skbs to the sending socket, so the there's no
need to orphan the skb before trimming it.

Removing the skb_orphan() call is required for mmap'ed netlink, which uses
a netlink specific skb destructor that must not be invoked before the
final freeing of the skb.

Subject: [PATCH 1377/1722] netlink: add netlink_skb_set_owner_r()

For mmap'ed I/O a netlink specific skb destructor needs to be invoked
after the final kfree_skb() to clean up state. This doesn't work currently
since the skb's ownership is transfered to the receiving socket using
skb_set_owner_r(), which orphans the skb, thereby invoking the destructor
prematurely.

Since netlink doesn't account skbs to the originating socket, there's no
need to orphan the skb. Add a netlink specific skb_set_owner_r() variant
that does not orphan the skb and use a netlink specific destructor to
call sock_rfree().

From: Patrick McHardy <kaber@trash.net>
Date: Wed, 17 Apr 2013 06:47:02 +0000
Subject: [PATCH 1379/1722] netlink: add mmap'ed netlink helper functions

Add helper functions for looking up mmap'ed frame headers, reading and
writing their status, allocating skbs with mmap'ed data areas and a poll
function.

Subject: [PATCH 1380/1722] netlink: implement memory mapped sendmsg()

Add support for mmap'ed sendmsg() to netlink. Since the kernel validates
received messages before processing them, the code makes sure userspace
can't modify the message contents after invoking sendmsg(). To do that
only a single mapping of the TX ring is allowed to exist and the socket
must not be shared. If either of these two conditions does not hold, it
falls back to copying.

Subject: [PATCH 1381/1722] netlink: implement memory mapped recvmsg()

Add support for mmap'ed recvmsg(). To allow the kernel to construct messages
into the mapped area, a dataless skb is allocated and the data pointer is
set to point into the ring frame. This means frames will be delivered to
userspace in order of allocation instead of order of transmission. This
usually doesn't matter since the order is either not determinable by
userspace or message creation/transmission is serialized. The only case
where this can have a visible difference is nfnetlink_queue. Userspace
can't assume mmap'ed messages have ordered IDs anymore and needs to check
this if using batched verdicts.

For non-mapped sockets, nothing changes.

Subject: [PATCH 1382/1722] netlink: add flow control for memory mapped I/O

Add flow control for memory mapped RX. Since user-space usually doesn't
invoke recvmsg() when using memory mapped I/O, flow control is performed
in netlink_poll(). Dumps are allowed to continue if at least half of the
ring frames are unused.

+This file documents how to use memory mapped I/O with netlink.
+
+Author: Patrick McHardy <kaber@trash.net>
+
+Overview
+--------
+
+Memory mapped netlink I/O can be used to increase throughput and decrease
+overhead of unicast receive and transmit operations. Some netlink subsystems
+require high throughput, these are mainly the netfilter subsystems
+nfnetlink_queue and nfnetlink_log, but it can also help speed up large
+dump operations of f.i. the routing database.
+
+Memory mapped netlink I/O used two circular ring buffers for RX and TX which
+are mapped into the processes address space.
+
+The RX ring is used by the kernel to directly construct netlink messages into
+user-space memory without copying them as done with regular socket I/O,
+additionally as long as the ring contains messages no recvmsg() or poll()
+syscalls have to be issued by user-space to get more message.
+
+The TX ring is used to process messages directly from user-space memory, the
+kernel processes all messages contained in the ring using a single sendmsg()
+call.
+
+Usage overview
+--------------
+
+In order to use memory mapped netlink I/O, user-space needs three main changes:
+
+- ring setup
+- conversion of the RX path to get messages from the ring instead of recvmsg()
+- conversion of the TX path to construct messages into the ring
+
+Ring setup is done using setsockopt() to provide the ring parameters to the
+kernel, then a call to mmap() to map the ring into the processes address space:
+
+- setsockopt(fd, SOL_NETLINK, NETLINK_RX_RING, &params, sizeof(params));
+- setsockopt(fd, SOL_NETLINK, NETLINK_TX_RING, &params, sizeof(params));
+- ring = mmap(NULL, size, PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0)
+
+Usage of either ring is optional, but even if only the RX ring is used the
+mapping still needs to be writable in order to update the frame status after
+processing.
+
+Conversion of the reception path involves calling poll() on the file
+descriptor, once the socket is readable the frames from the ring are
+processsed in order until no more messages are available, as indicated by
+a status word in the frame header.
+
+On kernel side, in order to make use of memory mapped I/O on receive, the
+originating netlink subsystem needs to support memory mapped I/O, otherwise
+it will use an allocated socket buffer as usual and the contents will be
+ copied to the ring on transmission, nullifying most of the performance gains.
+Dumps of kernel databases automatically support memory mapped I/O.
+
+Conversion of the transmit path involves changing message contruction to
+use memory from the TX ring instead of (usually) a buffer declared on the
+stack and setting up the frame header approriately. Optionally poll() can
+be used to wait for free frames in the TX ring.
+
+Structured and definitions for using memory mapped I/O are contained in
+<linux/netlink.h>.
+
+RX and TX rings
+----------------
+
+Each ring contains a number of continous memory blocks, containing frames of
+fixed size dependant on the parameters used for ring setup.
+
+Ring:	[ block 0 ]
+		[ frame 0 ]
+		[ frame 1 ]
+	[ block 1 ]
+		[ frame 2 ]
+		[ frame 3 ]
+	...
+	[ block n ]
+		[ frame 2 * n ]
+		[ frame 2 * n + 1 ]
+
+The blocks are only visible to the kernel, from the point of view of user-space
+the ring just contains the frames in a continous memory zone.
+
+The ring parameters used for setting up the ring are defined as follows:
+
+struct nl_mmap_req {
+	unsigned int	nm_block_size;
+	unsigned int	nm_block_nr;
+	unsigned int	nm_frame_size;
+	unsigned int	nm_frame_nr;
+};
+
+Frames are grouped into blocks, where each block is a continous region of memory
+and holds nm_block_size / nm_frame_size frames. The total number of frames in
+the ring is nm_frame_nr. The following invariants hold:
+
+- frames_per_block = nm_block_size / nm_frame_size
+
+- nm_frame_nr = frames_per_block * nm_block_nr
+
+Some parameters are constrained, specifically:
+
+- nm_block_size must be a multiple of the architectures memory page size.
+  The getpagesize() function can be used to get the page size.
+
+- nm_frame_size must be equal or larger to NL_MMAP_HDRLEN, IOW a frame must be
+  able to hold at least the frame header
+
+- nm_frame_size must be smaller or equal to nm_block_size
+
+- nm_frame_size must be a multiple of NL_MMAP_MSG_ALIGNMENT
+
+- nm_frame_nr must equal the actual number of frames as specified above.
+
+When the kernel can't allocate phsyically continous memory for a ring block,
+it will fall back to use physically discontinous memory. This might affect
+performance negatively, in order to avoid this the nm_frame_size parameter
+should be chosen to be as small as possible for the required frame size and
+the number of blocks should be increased instead.
+
+Ring frames
+------------
+
+Each frames contain a frame header, consisting of a synchronization word and some
+meta-data, and the message itself.
+
+Frame:	[ header message ]
+
+The frame header is defined as follows:
+
+struct nl_mmap_hdr {
+	unsigned int	nm_status;
+	unsigned int	nm_len;
+	__u32		nm_group;
+	/* credentials */
+	__u32		nm_pid;
+	__u32		nm_uid;
+	__u32		nm_gid;
+};
+
+- nm_status is used for synchronizing processing between the kernel and user-
+  space and specifies ownership of the frame as well as the operation to perform
+
+- nm_len contains the length of the message contained in the data area
+
+- nm_group specified the destination multicast group of message
+
+- nm_pid, nm_uid and nm_gid contain the netlink pid, UID and GID of the sending
+  process. These values correspond to the data available using SOCK_PASSCRED in
+  the SCM_CREDENTIALS cmsg.
+
+The possible values in the status word are:
+
+- NL_MMAP_STATUS_UNUSED:
+	RX ring:	frame belongs to the kernel and contains no message
+			for user-space. Approriate action is to invoke poll()
+			to wait for new messages.
+
+	TX ring:	frame belongs to user-space and can be used for
+			message construction.
+
+- NL_MMAP_STATUS_RESERVED:
+	RX ring only:	frame is currently used by the kernel for message
+			construction and contains no valid message yet.
+			Appropriate action is to invoke poll() to wait for
+			new messages.
+
+- NL_MMAP_STATUS_VALID:
+	RX ring:	frame contains a valid message. Approriate action is
+			to process the message and release the frame back to
+			the kernel by setting the status to
+			NL_MMAP_STATUS_UNUSED or queue the frame by setting the
+			status to NL_MMAP_STATUS_SKIP.
+
+	TX ring:	the frame contains a valid message from user-space to
+			be processed by the kernel. After completing processing
+			the kernel will release the frame back to user-space by
+			setting the status to NL_MMAP_STATUS_UNUSED.
+
+- NL_MMAP_STATUS_COPY:
+	RX ring only:	a message is ready to be processed but could not be
+			stored in the ring, either because it exceeded the
+			frame size or because the originating subsystem does
+			not support memory mapped I/O. Appropriate action is
+			to invoke recvmsg() to receive the message and release
+			the frame back to the kernel by setting the status to
+			NL_MMAP_STATUS_UNUSED.
+
+- NL_MMAP_STATUS_SKIP:
+	RX ring only:	user-space queued the message for later processing, but
+			processed some messages following it in the ring. The
+			kernel should skip this frame when looking for unused
+			frames.
+
+The data area of a frame begins at a offset of NL_MMAP_HDRLEN relative to the
+frame header.
+
+TX limitations
+--------------
+
+Kernel processing usually involves validation of the message received by
+user-space, then processing its contents. The kernel must assure that
+userspace is not able to modify the message contents after they have been
+validated. In order to do so, the message is copied from the ring frame
+to an allocated buffer if either of these conditions is false:
+
+- only a single mapping of the ring exists
+- the file descriptor is not shared between processes
+
+This means that for threaded programs, the kernel will fall back to copying.
+
+Example
+-------
+
+Ring setup:
+
+	unsigned int block_size = 16 * getpagesize();
+	struct nl_mmap_req req = {
+		.nm_block_size		= block_size,
+		.nm_block_nr		= 64,
+		.nm_frame_size		= 16384,
+		.nm_frame_nr		= 64 * block_size / 16384,
+	};
+	unsigned int ring_size;
+	void *rx_ring, *tx_ring;
+
+	/* Configure ring parameters */
+	if (setsockopt(fd, NETLINK_RX_RING, &req, sizeof(req)) < 0)
+		exit(1);
+	if (setsockopt(fd, NETLINK_TX_RING, &req, sizeof(req)) < 0)
+		exit(1)
+
+	/* Calculate size of each invididual ring */
+	ring_size = req.nm_block_nr * req.nm_block_size;
+
+	/* Map RX/TX rings. The TX ring is located after the RX ring */
+	rx_ring = mmap(NULL, 2 * ring_size, PROT_READ | PROT_WRITE,
+		       MAP_SHARED, fd, 0);
+	if ((long)rx_ring == -1L)
+		exit(1);
+	tx_ring = rx_ring + ring_size:
+
+Message reception:
+
+This example assumes some ring parameters of the ring setup are available.
+
+	unsigned int frame_offset = 0;
+	struct nl_mmap_hdr *hdr;
+	struct nlmsghdr *nlh;
+	unsigned char buf[16384];
+	ssize_t len;
+
+	while (1) {
+		struct pollfd pfds[1];
+
+		pfds[0].fd	= fd;
+		pfds[0].events	= POLLIN | POLLERR;
+		pfds[0].revents	= 0;
+
+		if (poll(pfds, 1, -1) < 0 && errno != -EINTR)
+			exit(1);
+
+		/* Check for errors. Error handling omitted */
+		if (pfds[0].revents & POLLERR)
+			<handle error>
+
+		/* If no new messages, poll again */
+		if (!(pfds[0].revents & POLLIN))
+			continue;
+
+		/* Process all frames */
+		while (1) {
+			/* Get next frame header */
+			hdr = rx_ring + frame_offset;
+
+			if (hdr->nm_status == NL_MMAP_STATUS_VALID)
+				/* Regular memory mapped frame */
+				nlh = (void *hdr) + NL_MMAP_HDRLEN;
+				len = hdr->nm_len;
+
+				/* Release empty message immediately. May happen
+				 * on error during message construction.
+				 */
+				if (len == 0)
+					goto release;
+			} else if (hdr->nm_status == NL_MMAP_STATUS_COPY) {
+				/* Frame queued to socket receive queue */
+				len = recv(fd, buf, sizeof(buf), MSG_DONTWAIT);
+				if (len <= 0)
+					break;
+				nlh = buf;
+			} else
+				/* No more messages to process, continue polling */
+				break;
+
+			process_msg(nlh);
+release:
+			/* Release frame back to the kernel */
+			hdr->nm_status = NL_MMAP_STATUS_UNUSED;
+
+			/* Advance frame offset to next frame */
+			frame_offset = (frame_offset + frame_size) % ring_size;
+		}
+	}
+
+Message transmission:
+
+This example assumes some ring parameters of the ring setup are available.
+A single message is constructed and transmitted, to send multiple messages
+at once they would be constructed in consecutive frames before a final call
+to sendto().
+
+	unsigned int frame_offset = 0;
+	struct nl_mmap_hdr *hdr;
+	struct nlmsghdr *nlh;
+	struct sockaddr_nl addr = {
+		.nl_family	= AF_NETLINK,
+	};
+
+	hdr = tx_ring + frame_offset;
+	if (hdr->nm_status != NL_MMAP_STATUS_UNUSED)
+		/* No frame available. Use poll() to avoid. */
+		exit(1);
+
+	nlh = (void *)hdr + NL_MMAP_HDRLEN;
+
+	/* Build message */
+	build_message(nlh);
+
+	/* Fill frame header: length and status need to be set */
+	hdr->nm_len	= nlh->nlmsg_len;
+	hdr->nm_status	= NL_MMAP_STATUS_VALID;
+
+	if (sendto(fd, NULL, 0, 0, &addr, sizeof(addr)) < 0)
+		exit(1);
+
+	/* Advance frame offset to next frame */
+	frame_offset = (frame_offset + frame_size) % ring_size;

Subject: [PATCH 1387/1722] qlcnic: Change 82xx adapter VLAN id endian type.

o 82xx adapter requires VLAN id in little endian format.
  Instead of passing vlan id parameter as __le16, pass the
  parameter as u16 and  use cpu_to_le16 at appropriate places.

From 97d8105cf3fb1eb84351ff4b69287ef7d25a4422 Mon Sep 17 00:00:00 2001
From: Rajesh Borundia <rajesh.borundia@qlogic.com>
Date: Fri, 19 Apr 2013 07:01:09 +0000
Subject: [PATCH 1388/1722] qlcnic: VF FLR implementation.

o FLR from Hypervisor - When hypervisor issues a VF FLR request,
  adapter notifies the parent PF driver of the FLR request for PF
  driver to perform any cleanup on behalf of that VF.
o FLR from VF Driver - VF driver may initiate a VF FLR request,
  if VF state needs to be cleaned up before a re-initialization.
  VF re-initialization during kdump is an example.
o PF driver cleans up all resources allocated on behalf of a  VF,
  on VF FLR notifications from the adapter or from the VF driver.

From 4000e7a78d12d71e37fcd2366c73fcb02e97fffb Mon Sep 17 00:00:00 2001
From: Rajesh Borundia <rajesh.borundia@qlogic.com>
Date: Fri, 19 Apr 2013 07:01:11 +0000
Subject: [PATCH 1390/1722] qlcnic: Support MAC address, Tx rate config.

o Add support for MAC address and Tx rate configuration
  per VF via iproute2 tool.
o Tx rate change is allowed while the guest is running
  and the VF driver is loaded.
o MAC address change is allowed only when VF driver
  is not loaded.

From 91b7282b613d4da65e8b4c87d521156cdc64c169 Mon Sep 17 00:00:00 2001
From: Rajesh Borundia <rajesh.borundia@qlogic.com>
Date: Fri, 19 Apr 2013 07:01:12 +0000
Subject: [PATCH 1391/1722] qlcnic: Support VLAN id config.

o Add support for VLAN id configuration per VF using
  iproute2 tool.
o VLAN id's 1-4094 are treated as PVID by the PF and
  Guest VLAN tagging is not allowed by default.
o PVID is disabled when the VLAN id is set to 0
o Guest VLAN tagging is allowed when the VLAN id is set to 4095.
o Only one Guest VLAN id  is supported.
o VLAN id can be changed only when the VF driver is not loaded.

Subject: [PATCH 1397/1722] net: socket: move ktime2ts to ktime header api

Currently, ktime2ts is a small helper function that is only used in
net/socket.c. Move this helper into the ktime API as a small inline
function, so that i) it's maintained together with ktime routines,
and ii) also other files can make use of it. The function is named
ktime_to_timespec_cond() and placed into the generic part of ktime,
since we internally make use of ktime_to_timespec(). ktime_to_timespec()
itself does not check the ktime variable for zero, hence, we name
this function ktime_to_timespec_cond() for only a conditional
conversion, and adapt its users to it.

Subject: [PATCH 1398/1722] packet: move hw/sw timestamp extraction into a
 small helper

This patch introduces a small, internal helper function, that is used by
PF_PACKET. Based on the flags that are passed, it extracts the packet
timestamp in the receive path. This is merely a refactoring to remove
some duplicate code in tpacket_rcv(), to make it more readable, and to
enable others to use this function in PF_PACKET as well, e.g. for TX.

Subject: [PATCH 1399/1722] bond: add support to read speed and duplex via
 ethtool

This patch adds support for the get_settings ethtool op to the bonding
driver.  This was motivated by users who wanted to get the speed of the
bond and compare that against throughput to understand utilization.
The behavior before this patch was added was problematic when computing
line utilization after trying to get link-speed and throughput via SNMP.

Output from ethtool looks like this for a round-robin bond:

Settings for bond0:
	Supported ports: [ ]
	Supported link modes:   Not reported
	Supported pause frame use: No
	Supports auto-negotiation: No
	Advertised link modes:  Not reported
	Advertised pause frame use: No
	Advertised auto-negotiation: No
	Speed: 11000Mb/s
	Duplex: Full
	Port: Other
	PHYAD: 0
	Transceiver: internal
	Auto-negotiation: off
	MDI-X: Unknown
	Link detected: yes

I tested this and verified it works as expected.  A test was also done
on a version backported to an older kernel and it worked well there.

v2: Switch to using ethtool_cmd_speed_set to set speed, added check to
SLAVE_IS_OK for each slave in bond, dropped mode-specific calculations
as they were not needed, and set port type to 'Other.'

v3: Fix useless assignment and checkpatch warning.

Subject: [PATCH 1400/1722] net: vlan: fix memory leak in vlan_info_rcu_free()

The following leak is reported by kmemleak:

The reason is that in vlan_info_rcu_free() we don't take the VLAN protocol
into account when iterating over the vlan_devices_array.

Subject: [PATCH 1404/1722] batman-adv: use the proper header len when checking
 the TTVN

Unicast packet might be of type either UNICAST or
UNICAST4ADDR.
In the two cases the header size is different, but the
mechanism checking the TTVN field was assuming it to be
always of the same type (UNICAST), so failing to access the
inner Ethernet header in case of UNICAST4ADDR.

Fix this by passing the real header length as argument.

In cfg80211_can_use_iftype_chan(), check for P2P Device

anything but makes the code a bit easier to read since
it may not be obvious for everyone at first that a P2P

 parameters

Some driver implementations need to know whether mandatory
admission control is required by the AP for some ACs. Add
a parameter to the TX queue parameters indicating this.

As there's currently no support for admission control in
mac80211's AP implementation, it's only ever set for the
client implementation.

Subject: [PATCH 1408/1722] mac80211: use synchronize_rcu() with rcu_barrier()

The RCU docs used to state that rcu_barrier() included a wait
for an RCU grace period; however the comments for rcu_barrier()
as of commit f0a0e6f... "rcu: Clarify memory-ordering properties
of grace-period primitives" contradict this.

So add back synchronize_{rcu,net}() to where they once were,
but keep the rcu_barrier()s for the call_rcu() callbacks.

Subject: [PATCH 1410/1722] mac80211: minstrel_ht: pick only supported rates
 for sta and group max*rates

minstrel_ht initializes max_tp_rate max_tp_rate2 and max_prob_rate to
zero both for minstrel_ht_sta and minstrel_mcs_group_data.
This is wrong since there is no guarantee that the 1st rate of any
group is supported.

Subject: [PATCH 1412/1722] cfg80211: introduce critical protocol indication
 from user-space

Some protocols need a more reliable connection to complete
successful in reasonable time. This patch adds a user-space
API to indicate the wireless driver that a critical protocol
is about to commence and when it is done, using nl80211 primitives
NL80211_CMD_CRIT_PROTOCOL_START and NL80211_CRIT_PROTOCOL_STOP.

There can be only on critical protocol session started per
registered cfg80211 device.

The driver can support this by implementing the cfg80211 callbacks
.crit_proto_start() and .crit_proto_stop(). Examples of protocols
that can benefit from this are DHCP, EAPOL, APIPA. Exactly how the
link can/should be made more reliable is up to the driver. Things
to consider are avoid scanning, no multi-channel operations, and
alter coexistence schemes.

From 0d528d85c519b755b6f4e1bafa3a39984370e1c1 Mon Sep 17 00:00:00 2001
From: Felix Fietkau <nbd@openwrt.org>
Date: Mon, 22 Apr 2013 16:14:41 +0200
Subject: [PATCH 1413/1722] mac80211: improve the rate control API

Allow rate control modules to pass a rate selection table to mac80211
and the driver. This allows drivers to fetch the most recent rate
selection from the sta pointer for already buffered frames. This allows
rate control to respond faster to sudden link changes and it is also a
step towards adding minstrel_ht support to drivers like iwlwifi.

When a driver sets IEEE80211_HW_SUPPORTS_RC_TABLE, mac80211 will not
fill info->control.rates with rates from the rate table (to preserve
explicit overrides by the rate control module). The driver then
explicitly calls ieee80211_get_tx_rates to merge overrides from
info->control.rates with defaults from the sta rate table.

From a85666627b7f10c4229716b6ffaffcf196a128ca Mon Sep 17 00:00:00 2001
From: Felix Fietkau <nbd@openwrt.org>
Date: Mon, 22 Apr 2013 16:14:42 +0200
Subject: [PATCH 1414/1722] mac80211/minstrel_ht: use the new rate control API

Pass the rate selection table to mac80211 from minstrel_ht_update_stats.
Only rates for sample attempts are set in info->control.rates.

Subject: [PATCH 1415/1722] mac80211/minstrel: use the new rate control API

Pass the rate selection table to mac80211 from minstrel_update_stats.
Only rates for sample attempts are set in info->control.rates, with deferred
sampling, only the second slot gets changed.

Subject: [PATCH 1417/1722] mwl8k: remove nonstandard rate 72 Mbps

This rate causes an overflow in the extended rates IE's data rate field,
with the overflowing bit setting the Basic Rate Set membership. This
results in a bogus 8 Mpbs basic rate, making clients checking them refuse
association.

Since the rate is likely unused anyway (HT will yield better rates between
supporting chips), we can just remove it.

This fixes association from wpa_supplicant and Android 4.x and newer.

Subject: [PATCH 1418/1722] rt2x00: Fix transmit power troubles on some Ralink
 RT30xx cards

Some cards on Ralink RT30xx chipset not have correctly TX_MIXER_GAIN
value in them EEPROM/EFUSE. In this case, we must use default value,
but always used EEPROM/EFUSE value. As result we have tranmitt power
range from -10dBm to +6dBm instead 0dBm to +16dBm.

Correctly value in EEPROM/EFUSE is one or more for RT3070 and two or
more for other RT30xx chips.

Tested on Canyon CNP-WF518N1 usb Wi-Fi dongle and Jorjin WN8020 usb
embedded Wi-Fi module.

Subject: [PATCH 1419/1722] ath9k: change DFS logging to use ath_dbg()

The DFS pattern detector was initially planned to reside on
a higher layer and used generic pr_*() logging functions.

Being part of ath9k, use ath_dbg() instead and make DFS log
ouput selectable via ATH_DBG_DFS (0x20000) at runtime.

This patch does not contain functional modifications.

Subject: [PATCH 1420/1722] ath9k: use GFP_ATOMIC under spinlock

This is called with spinlocks held so we have to use GFP_ATOMIC.  It's
the sc_pcu_lock in ath9k_stop() that's the issue.  The call tree looks
like this:

ath9k_stop()
ath_prepare_reset()
ath_stoprecv()
ath_flushrecv()
ath_rx_tasklet()
ath9k_dfs_process_phyerr()
pd->add_pulse() => dpd_add_pulse()
channel_detector_get()
channel_detector_create()
pri_detector_init()

channel_detector_create() uses GFP_ATOMIC as well.

Subject: [PATCH 1422/1722] ath9k: always set common->macaddr to the MAC adress
 of a virtual interface

In some cases it can be useful to change the MAC address of a virtual
interface to something that's completely different from the EEPROM
stored MAC address. In this case it is a bad idea to use the EEPROM MAC
address for calculating the BSSID mask, as that would make it too wide.

In one case a few devices have been observed to send ACKs for many
packets on the channel not directed at them, which results in a neat
Denial of Service attack on the channel.

Subject: [PATCH 1429/1722] rt2800: add rt2800_rx_filter_calibration procedure

Add procedure for both bands filter calibration and use it on individual
chipset init rfcsr subroutines.

Remove "Set back to initial state" code for 3290 since vendor driver
DPO_RT3290_LinuxSTA_V2600_20120508 does not include it.

Subject: [PATCH 1434/1722] rt2x00: provide separate information about TXWI &
 RXWI sizes

On new 2800 hardware sizes of TXWI & RXIW can be different than TXD
& RXD sizes, so we need to difference between them. Let's define
winfo_size as size of in buffer descriptor (TXWI & RXWI), and desc_size
of as size of additional descriptor - in separate DMA coherent buffer
for PCI hardware (TXD & RXD) and yet another in buffer descriptor for
USB hardware (TXINFO & RXINFO).

Change is rt2x00 wild, but should affect only 2800 driver.

Patch also fix beaconing for 5592usb AP mode.

Subject: [PATCH 1442/1722] brcmfmac: use lock in brcmf_fws_del_interface()

When deleting an interface in firmware-signalling module it will
clear any destination descriptors. To avoid concurrency issues it
should take the lock using brcmf_fws_lock().

Subject: [PATCH 1444/1722] brcmfmac: change return type for
 brcmf_rollback_toq() to void

The function brcmf_rollback_toq() is already called in error path
and its result should not override the initial error value. As the
function releases the sk_buff there is no need to return anything
so change return type to void.

In the dequeue worker the function brcmf_commit_skb() is called.
However, instead of increment the credit count upon success it
should break the for loop upon failure. Otherwise, it will result
in an endless loop.

Rx descriptors stored in non-cacheable memory area for DMA.
Non-cacheable memory causes long access time from CPU.

Copy rx descriptor to the skb->cb, and use this copy.
It provides faster memory access, and will be usefull to keep
Rx information for later processing (BACK reorder)

Subject: [PATCH 1451/1722] rt2x00: rt2800lib: rename rt2800_init_bbb_early to
 rt2800_init_bbp_early

The function is used for BBP register initialization,
fix the typo in the function name to reflect that.

The patch contains no functional changes.

Subject: [PATCH 1452/1722] rt2x00: Use more current logging styles, shrink
 object size

Reduce object space ~2% using more current logging styles.

Neaten and simplify logging macros.
Use wiphy_<level> where appropriate.
Coalesce formats.

Convert ERROR/WARNING/INFO macros to rt2x00_<level>
Convert EEPROM to rt2x00_eeprom_dbg
Convert PROBE_ERROR to rt2x00_probe_err
Convert DEBUG to rt2x00_dbg
Convert EEPROM to rt2x00_eeprom_dbg

priv->bss_mode uses NL80211_IFTYPE_* definitions.
HostCmd_BSS_MODE_IBSS is used in ad-hoc start/join command between
driver and firmware.

Coincidentally both HostCmd_BSS_MODE_IBSS and NL80211_IFTYPE_STATION
are defined as 2. That explains why nobody complained.

Subject: [PATCH 1466/1722] be2net: Don't log "Out of MCCQ wrbs" error

Don't log "Out of MCCQ wrbs" msg. When the driver doesn't receive any
response from the FW it already logs a "FW not responding" message.
The driver runs out of MCCQ wrbs much later. Also, this message can
swamp the kernel log in HW/FW error scenarios.

Subject: [PATCH 1469/1722] be2net: enable IOMMU pass through for be2net

This patch sets the coherent DMA mask to 64-bit after the be2net driver has
been acknowledged that the system is 64-bit DMA capable. The coherent DMA
mask is examined by the Intel IOMMU driver to determine whether to allow
pass through context mapping for all devices. With this patch, the be2net
driver combined with be2net compatible hardware provides comparable
performance to the case where vt-d is disabled. The main use-case for this
change is to decrease the time necessary to copy virtual machine memory
during KVM live migration instantiations.

This patch was tested on a system that enables the IOMMU in non-coherent
mode. Two DMA remapper issues were encountered in the previous version and
both patches have been committed.

 max TCP header

The maximum packet including header that can be handled by netfront / netback
wire format is 65535. Reduce gso_max_size accordingly.

Drop skb and print warning when skb->len > 65535. This can 1) save the effort
to send malformed packet to netback, 2) help spotting misconfiguration of
netfront in the future.

Subject: [PATCH 1472/1722] xen-netback: coalesce slots in TX path and fix
 regressions

This patch tries to coalesce tx requests when constructing grant copy
structures. It enables netback to deal with situation when frontend's
MAX_SKB_FRAGS is larger than backend's MAX_SKB_FRAGS.

With the help of coalescing, this patch tries to address two regressions
avoid reopening the security hole in XSA-39.

Regression 1. The reduction of the number of supported ring entries (slots)
per packet (from 18 to 17). This regression has been around for some time but
remains unnoticed until XSA-39 security fix. This is fixed by coalescing
slots.

Regression 2. The XSA-39 security fix turning "too many frags" errors from
just dropping the packet to a fatal error and disabling the VIF. This is fixed
by coalescing slots (handling 18 slots when backend's MAX_SKB_FRAGS is 17)
which rules out false positive (using 18 slots is legit) and dropping packets
using 19 to `max_skb_slots` slots.

To avoid reopening security hole in XSA-39, frontend sending packet using more
than max_skb_slots is considered malicious.

The behavior of netback for packet is thus:

    1-18            slots: valid
   19-max_skb_slots slots: drop and respond with an error
   max_skb_slots+   slots: fatal error

max_skb_slots is configurable by admin, default value is 20.

Also change variable name from "frags" to "slots" in netbk_count_requests.

Please note that RX path still has dependency on MAX_SKB_FRAGS. This will be
fixed with separate patch.

Subject: [PATCH 1473/1722] xen-netback: don't disconnect frontend when seeing
 oversize packet

Some frontend drivers are sending packets > 64 KiB in length. This length
overflows the length field in the first slot making the following slots have
an invalid length.

Turn this error back into a non-fatal error by dropping the packet. To avoid
having the following slots having fatal errors, consume all slots in the
packet.

This does not reopen the security hole in XSA-39 as if the packet as an
invalid number of slots it will still hit fatal error case.

Subject: [PATCH 1474/1722] mwifiex: fix use-after-free in beacon_ie processing

beacon_ie buffer is allocated in mwifiex_fill_new_bss_desc()
and the buffer pointer is saved in bss_desc->beacon_buf.
beacon_ie is freed before the function returns. However,
bss_desc->beacon_buf is still being accessed afterwards.

Fix it by freeing beacon_ie (bss_desc->beacon_buf) in
caller's scope.

Subject: [PATCH 1478/1722] qeth: Fix missing pointer update

qeth_hdr_chk_and_bounce() can possibly shift the skb->data
pointer. However, the existing code didn't update the hdr pointer,
which should point to skb->data, accordingly.
Symptoms of this issue are sporadic recoveries.

Subject: [PATCH 1481/1722] VXLAN: Allow L2 redirection with L3 switching

Allow L2 redirection when VXLAN L3 switching is enabled

This patch restricts L3 switching to destination MAC addresses that are
marked as routers in order to allow virtual IP appliances that do L2
redirection to function with VXLAN L3 switching enabled.

We use L3 switching on VXLAN networks to avoid extra hops when the nominal
router for cross-subnet traffic for a VM is remote and the ultimate
destination may be local, or closer to the local node. Currently, the
destination IP address takes precedence over the MAC address in all cases.
Some network appliances receive packets for a virtualized IP address and
redirect by changing the destination MAC address (only) to be the final
destination for packet processing. VXLAN tunnel endpoints with L3 switching
enabled may then overwrite this destination MAC address based on the packet IP
address, resulting in potential loops and, at least, breaking L2 redirections
that travel through tunnel endpoints.

This patch limits L3 switching to the intended case where the original
destination MAC address is a next-hop router and relies on the destination
MAC address for all other cases, thus allowing L2 redirection and L3 switching
to coexist peacefully.

struct sctp_packet is currently embedded into sctp_transport or

its member 'malloced' is always 0, thus a kfree() is never called.
Because of that, we can just remove this code.

This driver uses the crummy "| foo" style, putting the
logical operation at the beginning of lines.  Then
when the VLAN tag flag bits got changed the operator
ended up at both the end and the beginning of some lines.

Fix the build error by having it uniformly use the operator
at the end of the line.

Subject: [PATCH 1485/1722] batman-adv: fix global protection fault during
 soft_iface destruction

batadv_mesh_free() schedules some RCU callbacks which need the bat_priv struct
to do their jobs, while free_netdev(), which is called immediately after, is
destroying the private data.

Put an rcu_barrier() in the middle so that free_netdev() is invoked only after
all the callbacks returned.

This bug has been introduced by ab8f433dd39be94e8617cff2dfe9f7eca162eb15
("batman-adv: Move deinitialization of soft-interface to destructor")

Subject: [PATCH 1487/1722] ipvs: fix sparse warnings for ip_vs_conn listing

kbuild test robot reports for sparse warnings
in commit 088339a57d6042 ("ipvs: convert connection locking"):

net/netfilter/ipvs/ip_vs_conn.c:962:13: warning: context imbalance
	in 'ip_vs_conn_array' - wrong count at exit
include/linux/rcupdate.h:326:30: warning: context imbalance in
	'ip_vs_conn_seq_next' - unexpected unlock
include/linux/rcupdate.h:326:30: warning: context imbalance in
	'ip_vs_conn_seq_stop' - unexpected unlock

Fix it by running ip_vs_conn_array under RCU lock
to avoid conditional locking and by adding proper RCU
annotations.

Some service fields are in network order:

- netmask: used once in network order and also as prefix len for IPv6
- port

Other parameters are in host order:

- struct ip_vs_flags: flags and mask moved between user and kernel only
- sync state: moved between user and kernel only
- syncid: sent over network as single octet

Subject: [PATCH 1492/1722] ipvs: Use min3() in ip_vs_dbg_callid()

There are two motivations for this:

1. It improves readability to my eyes
2. Using nested min() calls results in a shadowed _min1 variable,
   which is a bit untidy. Sparse complained about this.

I have also replaced (size_t)64 with a variable of type size_t and value 64.
This also improves readability to my eyes.

Subject: [PATCH 1493/1722] ipvs: off by one in set_sctp_state()

The sctp_events[] come from sch->type in set_sctp_state().  They are
between 0-255 so that means we need 256 elements in the array.

I believe that because of how the code is aligned there is normally a
hole after sctp_events[] so this patch doesn't actually change anything.

Subject: [PATCH 1494/1722] ipvs: Use network byte order for sync message size

struct ip_vs_sync_mesg and ip_vs_sync_mesg_v0 are both sent across the wire
and used internally to store IPVS synchronisation messages.

Up until now the scheme used has been to convert the size field
to network byte order before sending a message on the wire and
convert it to host byte order when sending a message.

This patch changes that scheme to always treat the field
as being network byte order. This seems appropriate as
the structure is sent across the wire. And by consistently
treating the field has network byte order it is now possible
to take advantage of sparse to flag any future miss-use.

MIME-Version: 1.0

Content-Transfer-Encoding: 8bit

After comparing writes to registers at 0x000, 0x400 and 0x800 it seems
there are many very similar writes. So 0x000 offset is not for accessing
something totally different, but probably just the first out of three
cores.

Subject: [PATCH 1498/1722] b43: HT-PHY: do some extra TSSI setup after
 configuring TX
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After b43_phy_ht_tx_power_ctl_setup there are some extra radio ops:
 radio_read(0x08bf) -> 0x0001
radio_write(0x08bf) <- 0x0001
radio_write(0x0159) <- 0x0011
On N-PHY we write 0x11 to TSSI regs, so it's probably sth similar.

Subject: [PATCH 1499/1722] b43: HT-PHY: define regs for power estimation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In MMIO dumps of ndiswrapper there are following PHY ops:
phy_read(0x0118) -> 0x013d
phy_read(0x01ed) -> 0x993d
phy_read(0x0119) -> 0x012f
phy_read(0x01ee) -> 0x992f
phy_read(0x011a) -> 0x0139
phy_read(0x0969) -> 0x9939
It matches the code of wlc_phy_txpower_est_power_nphy (from brcm80211),
so we know the registers meaning.

Subject: [PATCH 1510/1722] b43: N-PHY: use enum for INTC override function
 argument
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Also make a function name shorter so we can easily fit 80 chars.

Subject: [PATCH 1515/1722] b43: N-PHY: don't use deprecated b43_radio_foo16
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

All radio ops are 16b (there is only 1 exception for reg 0x1), so we
deprecated b43_radio_read16 and b43_radio_write16 long time ago.

Subject: [PATCH 1521/1722] ath9k: apply coverage class on slottime too

According to 802.11-2007 17.3.8.6 (slot time), the slot time should
be increased by 3 us * coverage class. The code only increased the
ack timeout, which is fixed by this patch.

We have noticed in our long shot scenario that we see less collisions
with this patch.

Subject: [PATCH 1527/1722] ath9k: Use lockless variants for the RX fifo queue

The RX fifo can be accessed from the common tasklet or it can
be reaped/cleaned when RX is stopped, which is done when doing
a reset or channel change - this happens in process context.

Since it is ensured that there are no pending tasklets when
stopping RX and cleaning the FIFO, there is no need to use
SKB queue functions which take internal locks.

wrong buffer was DMA-unmapped, introducing warnings like the one below.
This patch fixes the issue.

 signal

When firmware signals the driver to remove a destination entry
it may have sk_buff packets queued for it. These should be freed.

Subject: [PATCH 1532/1722] brcmfmac: correct error handling in
 brcmf_fws_init()

In brcmf_fws_init() the error flows were not properly handled
and the caller ignored the return value. The only action that
is allowed to fail in brcmf_fws_init() is setting the tlv in
firmware as the feature is not supported on all devices.

Subject: [PATCH 1533/1722] brcmfmac: add credit borrowing mechanism

The firmware provides credits to the driver per WMM-AC. When
only AC_BE are to be transmitted to the firmware the driver
may use credits from other priorities to send AC_BE packets
towards the firmware.

Subject: [PATCH 1534/1722] mwifiex: replace ra_list_curr by list rotation.

After a packet is successfully transmitted, ra list is rotated, so the ra
next to the one transmitted, will be the first in the list. This way we
pick the ra' in a round robin fashion. This significantly simplifies
iteration in  mwifiex_wmm_get_highest_priolist_ptr to a call to
list_for_each_entry.
List rotation is done via list_move, where the head itself is temporarily
removed and then re-inserted after the item just transferred.

Subject: [PATCH 1535/1722] mwifiex: rework round robin scheduling of bss
 nodes.

Rotate bss prio list, so the bss next to the one served, will come first
in the list of bss' with equal priority. This way we pick bss nodes in a
round robin fashion. Using list rotation instead of a cur ptr simplifies
iteration to calling list_for_each_entry. List rotation is done via
list_move, where the head itself is temporarily removed and then
re-inserted after the bss just served.

Subject: [PATCH 1537/1722] Bluetooth: Fix sending write_le_host_supporte for
 LE-only controllers

The Bluetooth Core Specification (4.0) defines the Write LE Host
Supported HCI command as only available for controllers supporting
BR/EDR. This is further reflected in the Read Local Extended Features
HCI command also not being available for LE-only controllers. In other
words, host-side LE support is implicit for single-mode LE controllers
and doesn't have explicit HCI-level enablement.

This patch ensures that the LE setting is always exposed as enabled
through mgmt and returns a "rejected" response if user space tries to
toggle the setting. The patch also ensures that Write LE Host Supported
is never sent for LE-only controllers.

Subject: [PATCH 1540/1722] Bluetooth: Remove unneeded parameter from L2CAP ATT
 channel handling

The CID is fixed to L2CAP ATT channel and so there is no need to hand it
down to the handling function. Just use a constant instead.

Clean up the code by using native debugfs helpers, instead of implementing
them ourselves:

Subject: [PATCH 1542/1722] Bluetooth: btmrvl: release lock while waiting for
 fw download complete

If not winner, driver must release the sdio host lock, so the fw
download can progress. While holding the lock fw download is stalled
and the following error is produced:

[  235.746015] Bluetooth: FW failed to be active in time!
[  235.752799] Bluetooth: Downloading firmware failed!

Subject: [PATCH 1543/1722] Bluetooth: btmrvl: report error if
 verify_fw_download times out

FW does the synchronization of the different modules during init.
It will report different modules, that it is ready at different times.
The fw download 'winner' will be reported fw ready first. Without this
patch, btmrvl was already continuing before the FW told it too. Probably
on behalf of the 'winner' which then never sees FW ready and times out.

Subject: [PATCH 1544/1722] netlink: fix compilation after memory mapped
 patches
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Depending of the kernel configuration (CONFIG_UIDGID_STRICT_TYPE_CHECKS), we can
get the following errors:

net/netlink/af_netlink.c: In function ‘netlink_queue_mmaped_skb’:
net/netlink/af_netlink.c:663:14: error: incompatible types when assigning to type ‘__u32’ from type ‘kuid_t’
net/netlink/af_netlink.c:664:14: error: incompatible types when assigning to type ‘__u32’ from type ‘kgid_t’
net/netlink/af_netlink.c: In function ‘netlink_ring_set_copied’:
net/netlink/af_netlink.c:693:14: error: incompatible types when assigning to type ‘__u32’ from type ‘kuid_t’
net/netlink/af_netlink.c:694:14: error: incompatible types when assigning to type ‘__u32’ from type ‘kgid_t’

We must use the helpers to get the uid and gid, and also take care of user_ns.

Fix suggested by Eric W. Biederman <ebiederm@xmission.com>.

From ec693d47010e8302e61e0bdf3f47496c5610641a Mon Sep 17 00:00:00 2001
From: Amir Vadai <amirv@mellanox.com>
Date: Tue, 23 Apr 2013 06:06:49 +0000
Subject: [PATCH 1547/1722] net/mlx4_en: Add HW timestamping (TS) support

The patch allows to enable/disable HW timestamping for incoming and/or
outgoing packets. It adds and initializes all structs and callbacks
needed by kernel TS API.
To enable/disable HW timestamping appropriate ioctl should be used.
Currently HWTSTAMP_FILTER_ALL/NONE and HWTSAMP_TX_ON/OFF only are
supported.
When enabling TS on receive flow - VLAN stripping will be disabled.
Also were made all relevant changes in RX/TX flows to consider TS request
and plant HW timestamps into relevant structures.
mlx4_ib was fixed to compile with new mlx4_cq_alloc() signature.

Subject: [PATCH 1548/1722] net/mlx4_en: Support software timestamping

Kernel software timestamping requires that the driver calls skb_tx_timestamp
just before passing the skb to the HW MAC layer. This patch adds this call.

Subject: [PATCH 1549/1722] net/mlx4_en: Add a service task

Add a service task to run tasks that needed to be executed periodically.
Currently the only task is a watchdog to catch NIC clock overflow, to make
timestamping accurate.
Will move the statistics task into this framework in a later patch.

Subject: [PATCH 1550/1722] bnx2x: prevent GRO false checksum claims

This patch introduces a more robust error handling flow in case of incorrect
behaviour by the FW when passing on GRO aggregations.

Although this should never happen (i.e., this is merely a theoretical fix),
if the bnx2x driver was to receive a GRO from FW with protocol other than
IPv4/IPv6, the driver would falsely claim to have performed partial
checksum and set various incorrect fields in the skb header.

Current behaviour of the bnx2x driver (i.e., print an error) is insufficient.
This patch remedies this by simply preventing the false claims.

Subject: [PATCH 1551/1722] bnx2x: Allow RX/TX pause control in autoneg

Currently, when link is configured to auto-negotiate the flow control,
disabling RX/TX pause via ethtool doesn't work.

This fixes the behaviour, advertising asymmetric pause in case either one
is exclusively enabled.

Subject: [PATCH 1553/1722] bnx2x: Fix memory leak

There exists an `allocation race' between the CNIC and bnx2x drivers,
in which both drivers allocate the same t2 memory while disregarding a possible
previous allocation.

Additionally, due to the current order of memory releases, some of the
ILT memory in the driver is not released correctly when unloading the driver.

Subject: [PATCH 1554/1722] bnx2x: Allow recovery from second slot reset

As part of PCIe Advanced Error Reporting flow, if a fatal PCI error occurs,
the AER driver will cause bnx2x's PCI-core to reset. The driver's PCI error
handlers will in turn restore the PCI configuration space values by calling
`pci_restore_state'.

However, as bnx2x does not save the PCI configuration after restoration,
An additional fatal PCI error will leave the function in an unstable state
until reboot, as the registers in the PCI configuration space will contain
reset values.

Subject: [PATCH 1562/1722] be2net: Remove an incorrect pvid check in Tx

To work-around a HW bug that corrupts certain packets while inserting
a pvid, the driver needs to invoke a special hack in firmware to avoid
the VLAN tagging in the HW. Since this logic is missing from the driver,
removing the check for pvid.

Subject: [PATCH 1563/1722] be2net: fix a Tx stall bug caused by a specific
 ipv6 packet

The ASIC could lockup in the transmit path when it tries
to insert VLAN in a specific ipv6 packet.
1) Identify the packet which can cause this.
2) Check if the firmware provides a workaround to prevent this.
3) If workaround is not present, drop the packet.
4) If the firmware provides a workaround, insert the VLAN tag in the
packet and inform the firmware to skip further VLAN insertions.

Subject: [PATCH 1564/1722] be2net: Fix PVID tag offload for packets with
 inline VLAN tag.

BE3 HW in UMC mode could wrongly double tag a packet with PVID
when the packet already has a inlined VLAN tag.
In UMC mode, When HW finds that a packet is already VLAN tagged
PVID should not be inserted into the packet.
To fix this use the FW hack to instruct the HW to skip PVID tagging.

The variable wol_supported really is just checking whether it is enabled, rather
than whether it is supported. If it is enabled it will be supported, but this
does not necessarily hold true the other way around. This patch renames the
variable to avoid confusion.

This patch adds LX support to 82599 devices. This is an alternate patch to
the one suggested by Stefan Behte <s.behte@babiel.com>

In addition this patch includes some cleanups such as:
- removed parenthesis around "x == y ||" lines inside an if statement for
consistency.
- grouped the sx/lx sfp types along with srlr in ixgbe_get_settings() since
they all have the same supported, advertised and port values.

Subject: [PATCH 1571/1722] igb: SERDES loopback sigdetect bit on i210 devices

This patch implements SERDES loopback configuration for i210 devices by
unsetting sigdetect bit, so as to fix Ethtool loopback test failure. Old
sigdetect code is also simplified to take care of all devices newer than 82580

Subject: [PATCH 1572/1722] igb: Add SMBI semaphore to I210/I211

It was previously thought that, since I210/I211 are single port devices,
they did not need the SMBI semaphore. This is not the case. Add support for
the SMBI semaphore.

Subject: [PATCH 1573/1722] pci: Add SRIOV helper function to determine if VFs
 are assigned to guest

This function is meant to add a helper function that will determine if a PF
has any VFs that are currently assigned to a guest.  We currently have been
implementing this function per driver, and going forward I would like to avoid
that by making this function generic and using this helper.

v2: Removed extern from declaration of pci_vfs_assigned in pci.h and return
    0 if SR-IOV is disabled with is inline with other PCI SRIOV functions.

Subject: [PATCH 1574/1722] igb: Use pci_vfs_assigned instead of
 igb_vfs_are_assigned

This change makes it so that the igb driver uses the generic helper
pci_vfs_assigned instead of the igb specific function igb_vfs_are_assigned.

Subject: [PATCH 1575/1722] igb: display a warning message when SmartSpeed
 works

Current igb driver doesn't tell nothing when Link Speed is downgraded due to
SmartSpeed.  As a result, users suspect that there is something wrong with
NIC.  If the cause of it is SmartSpeed, there is no means to replace NIC. This
patch make igb notify users that SmartSpeed worked.

Subject: [PATCH 1576/1722] igb: Retain HW VLAN filtering while in promiscuous
 + VT mode

When using the new bridge FDB interface to allow SR-IOV virtual function
network devices to communicate with SW bridged network devices the
physical function is placed into promiscuous mode and hardware VLAN
filtering is disabled.  This defeats the ability to use VLAN tagging
to isolate user networks.  When the device is in promiscuous mode and
VT mode simultaneously ensure that VLAN hardware filtering remains
enabled.

Subject: [PATCH 1582/1722] packet: enable hardware tx timestamping on tpacket
 ring

Currently, we only have software timestamping for the TX ring buffer
path, but this limitation stems rather from the implementation. By
just reusing tpacket_get_timestamp(), we can also allow hardware
timestamping just as in the RX path.

Subject: [PATCH 1584/1722] packet: if hw/sw ts enabled in rx/tx ring, report
 which ts we got

Currently, there is no way to find out which timestamp is reported in
tpacket{,2,3}_hdr's tp_sec, tp_{n,u}sec members. It can be one of
SOF_TIMESTAMPING_SYS_HARDWARE, SOF_TIMESTAMPING_RAW_HARDWARE,
SOF_TIMESTAMPING_SOFTWARE, or a fallback variant late call from the
PF_PACKET code in software.

Therefore, report in the tp_status member of the ring buffer which
timestamp has been reported for RX and TX path. This should not break
anything for the following reasons: i) in RX ring path, the user needs
to test for tp_status & TP_STATUS_USER, and later for other flags as
well such as TP_STATUS_VLAN_VALID et al, so adding other flags will
do no harm; ii) in TX ring path, time stamps with PACKET_TIMESTAMP
socketoption are not available resp. had no effect except that the
application setting this is buggy. Next to TP_STATUS_AVAILABLE, the
user also should check for other flags such as TP_STATUS_WRONG_FORMAT
to reclaim frames to the application. Thus, in case TX ts are turned
off (default case), nothing happens to the application logic, and in
case we want to use this new feature, we now can also check which of
the ts source is reported in the status field as provided in the docs.

There's a 4 byte hole in packet_ring_buffer structure before
prb_bdqc, that can be filled with 'pending' member, thus we can
reduce the overall structure size from 224 bytes to 216 bytes.
This also has the side-effect, that in struct packet_sock 2*4 byte
holes after the embedded packet_ring_buffer members are removed,
and overall, packet_sock can be reduced by 1 cacheline:

Before: size: 1344, cachelines: 21, members: 24
After:  size: 1280, cachelines: 20, members: 24

Subject: [PATCH 1587/1722] packet: account statistics only in tpacket_stats_u

Currently, packet_sock has a struct tpacket_stats stats member for
TPACKET_V1 and TPACKET_V2 statistic accounting, and with TPACKET_V3
``union tpacket_stats_u stats_u'' was introduced, where however only
statistics for TPACKET_V3 are held, and when copied to user space,
TPACKET_V3 does some hackery and access also tpacket_stats' stats,
although everything could have been done within the union itself.

Unify accounting within the tpacket_stats_u union so that we can
remove 8 bytes from packet_sock that are there unnecessary. Note that
even if we switch to TPACKET_V3 and would use non mmap(2)ed option,
this still works due to the union with same types + offsets, that are
exposed to the user space.

Subject: [PATCH 1588/1722] sfc: Fix naming of MTD partitions for FPGA bitfiles

efx_mcdi_get_board_cfg() uses a buffer for the firmware response that
is only large enough to hold subtypes for the originally defined set
of NVRAM partitions.  Longer responses are truncated, and we may read
off the end of the buffer when copying out subtypes for additional
partitions.  In particular, this can result in the MTD partition for
an FPGA bitfile being named e.g. 'eth5 sfc_fpga:00' when it should be
'eth5 sfc_fpga:01'.  This means the firmware update tool (sfupdate)
can't tell which bitfile should be written to the partition.

Correct the response buffer size.

This reverts commit 068a2de57ddf4f4 (net: release dst entry while
cache-hot for GSO case too)

Before GSO packet segmentation, we already take care of skb->dst if it
can be released.

There is no point adding extra test for every segment in the gso loop.

Subject: [PATCH 1591/1722] genl: Allow concurrent genl callbacks.

All genl callbacks are serialized by genl-mutex. This can become
bottleneck in multi threaded case.
Following patch adds an parameter to genl_family so that a
particular family can get concurrent netlink callback without
genl_lock held.
New rw-sem is used to protect genl callback from genl family unregister.
in case of parallel_ops genl-family read-lock is taken for callbacks and
write lock is taken for register or unregistration for any family.
In case of locked genl family semaphore and gel-mutex is locked for
any openration.

Subject: [PATCH 1592/1722] openvswitch: Use parallel_ops genl.

OVS locking was recently changed to have private OVS lock which
simplified overall locking.  Therefore there is no need to have
another global genl lock to protect OVS data structures.  Following
patch uses of parallel_ops genl family for OVS.  This also allows
more granual OVS locking using ovs_mutex for protecting OVS data
structures, which gives more concurrencey.  E.g multiple genl
operations OVS_PACKET_CMD_EXECUTE can run in parallel, etc.

Subject: [PATCH 1593/1722] gianfar: do not advertise any alarm capability.

An early draft of the PHC patch series included an alarm in the
gianfar driver. During the review process, the alarm code was dropped,
but the capability removal was overlooked. This patch fixes the issue
by advertising zero alarms.

This patch should be applied to every 3.x stable kernel.

The sockaddr_ax25 struct has a 3 byte hole between ->sax25_call and

stack data to userspace.

Subject: [PATCH 1597/1722] NFC: llcp: two bugs in ->getname()

The sockaddr_nfc_llcp struct has as hole between ->sa_family and
->dev_idx so I've added a memset() to clear it and prevent an
information leak.

Also the ->nfc_protocol element wasn't set so I've added that.

"uaddr->sa_family" and "llcp_addr->sa_family" are the same thing but
it's less confusing to use llcp_addr consistently throughout.

Subject: [PATCH 1598/1722] tuntap: correct the return value in tun_set_iff()

commit (3be8fbab tuntap: fix error return code in tun_set_iff()) breaks the
creation of multiqueue tuntap since it forbids to create more than one queues
for a multiqueue tuntap device. We need return 0 instead -EBUSY here since we
don't want to re-initialize the device when one or more queues has been already
attached. Add a comment and correct the return value to zero.

(e.g., kdump), it is possible for the chip to generate an interrupt without
any apparent reason once interrupts are requested.

Due to an erroneous initialization of resources, some of the bnx2x structs
which are required for interrupt handling are initialized only after an
interface's interrupt is requested from the OS.

As a result, once such a spurious interrupt occurs, it will cause a NULL
pointer dereference - the driver will access those structs in its interrupt
handling routine.

This patch change the interrupt request scheme so that bnx2x would only
request interrupts from the kernel after it has finished initializing
all the inner structs required for interrupt handling.

Subject: [PATCH 1603/1722] bonding: fix locking in enslave failure path

In commit 3c5913b53fefc9d9e15a2d0f93042766658d9f3f ("bonding:
primary_slave & curr_active_slave are not cleaned on enslave failure")
I didn't account for the use of curr_active_slave without curr_slave_lock
and since there are such users, we should hold bond->lock for writing while
setting it to NULL (in the NULL case we don't need the curr_slave_lock).
Keeping the bond lock as to avoid the extra release/acquire cycle.

Subject: [PATCH 1604/1722] bnx2x, bnx2fc: Use per port max exchange resources

The firmware supports a maximum of 4K FCoE exchanges. In 4-port devices,
or when working in multi-function mode, this resource needs to be distributed
between the various possible FCoE functions.

This information needs to be calculated by bnx2x and propagated into bnx2fc
via cnic. bnx2fc can then use this value to calculate corresponding xid
resources instead of using global constants.

Subject: [PATCH 1606/1722] net/davinci_cpdma: don't check for jiffies with
 interrupts

__cpdma_chan_process() holds the lock with interrupts off (and its
caller as well), same goes for cpdma_ctlr_start(). With interrupts off,
jiffies will not make any progress and if the wait condition never gets
true we wait for ever.
Tgis patch adds a a simple udelay and counting down attempt.

Subject: [PATCH 1607/1722] net/cpsw: don't continue if we miss to allocate rx
 skbs

if during "ifconfig up" we run out of mem we continue regardless how
many skbs we got. In worst case we have zero RX skbs and can't ever
receive further packets since the RX skbs are never reallocated. If
cpdma_chan_submit() fails we even leak the skb.
This patch changes the behavior here:
If we fail to allocate an skb during bring up we don't continue and
report that error. Same goes for errors from cpdma_chan_submit().
While here I changed to __netdev_alloc_skb_ip_align() so GFP_KERNEL can
be used.

Subject: [PATCH 1608/1722] net/cpsw: don't rely only on netif_running() to
 check which device is active

netif_running() reports false before the ->ndo_stop() callback is
called. That means if one executes "ifconfig down" and the system
receives an interrupt before the interrupt source has been disabled we
hang for always for two reasons:
- we never disable the interrupt source because devices claim to be
  already inactive and don't feel responsible.
- since the ISR always reports IRQ_HANDLED the line is never deactivated
  because it looks like the ISR feels responsible.

This patch changes the logic in the ISR a little:
- If none of the status registers reports an active source (RX or TX,
  misc is ignored because it is not actived) we leave with IRQ_NONE.
- the interrupt is deactivated
- The first active network device is taken and napi is scheduled. If
  none are active (a small race window between ndo_down() and the
  interrupt the) then we leave and should not come back because the
  source is off.
  There is no need to schedule the second NAPI because both share the
  same dma queue.

Subject: [PATCH 1610/1722] net/cpsw: redo rx skb allocation in rx path

In case that we run into OOM during the allocation of the new rx-skb we
don't get one and we have one skb less than we used to have. If this
continues to happen then we end up with no rx-skbs at all.
This patch changes the following:
- if we fail to allocate the new skb, then we treat the currently
  completed skb as the new one and so drop the currently received data.
- instead of testing multiple times if the device is gone we rely one
  the status field which is set to -ENOSYS in case the channel is going
  down and incomplete requests are purged.
  cpdma_chan_stop() removes most of the packages with -ENOSYS. The
  currently active packet which is removed has the "tear down" bit set.
  So if that bit is set, we send ENOSYS as well otherwise we pass the
  status bits which are required to figure out which of the two possible
  just finished.

Subject: [PATCH 1612/1722] net/cpsw: make sure modules remove does not leak
 any ressources

This driver does not clean up properly after leaving. Here is a list:
- Use unregister_netdev(). free_netdev() is good but not enough
- Use the above also on the other ndev in case of dual mac
- Free data.slave_data. The name of the strucre makes it look like
  it is platform_data but it is not. It is just a trick!
- Free all irqs. Again: freeing one irq is good start, but freeing all
  of them is better.

With this rmmod & modprobe of cpsw seems to work. The remaining issue
is:
|WARNING: at fs/sysfs/dir.c:536 sysfs_add_one+0x9c/0xd4()
|sysfs: cannot create duplicate filename '/devices/ocp.2/4a100000.ethernet/4a101000.mdio'
|WARNING: at lib/kobject.c:196 kobject_add_internal+0x1a4/0x1c8()

comming from of_platform_populate() and I am not sure that this belongs
here.

Subject: [PATCH 1614/1722] net/cpsw: fix irq_disable() with threaded
 interrupts

During high throughput it is likely that we receive both: an RX and TX
interrupt. The normal behaviour is that once we enter the ISR the
interrupts are disabled in the IRQ chip and so the ISR is invoked only
once and the interrupt line is disabled once. It will be re-enabled
after napi completes.
With threaded interrupts on the other hand the interrupt the interrupt
is disabled immediately and the ISR is marked for "later". By having TX
and RX interrupt marked pending we invoke them both and disable the
interrupt line twice. The napi callback is still executed once and so
after it completes we remain with interrupts disabled.

The initial patch simply removed the cpsw_{enable|disable}_irq() calls
and it worked well on my AM335X ES1.0 (beagle bone). On ES2.0 (beagle
bone black) it caused an never ending interrupt (even after the mask via
cpsw_intr_disable()) according to Mugunthan V N. Since I don't have the
ES2.0 and no idea what is going on this patch tracks the state of the
irq_disable() call and execute it only when not yet done.
The book keeping is done on the first struct since with dual_emac we can
have two of those and only one interrupt line.

Subject: [PATCH 1615/1722] net: fix address check in rtnl_fdb_del

Commit 6681712d67eef14c4ce793561c3231659153a320
	vxlan: generalize forwarding tables

relaxed the address checks in rtnl_fdb_del() to use is_zero_ether_addr().
This allows users to add multicast addresses using the fdb API.  However,
the check in rtnl_fdb_del() still uses a more strict
is_valid_ether_addr() which rejects multicast addresses.  Thus it
is possible to add an fdb that can not be later removed.
Relax the check in rtnl_fdb_del() as well.

Subject: [PATCH 1616/1722] VSOCK: Fix misc device registration

When we call vsock_core_init to init VSOCK the second time,
vsock_device.minor still points to the old dynamically allocated minor
number. misc_register will allocate it for us successfully as if we were
asking for a static one. However, when other user call misc_register to
allocate a dynamic minor number, it will give the one used by
vsock_core_init(), causing this:

  [  405.470687] WARNING: at fs/sysfs/dir.c:536 sysfs_add_one+0xcc/0xf0()
  [  405.470689] Hardware name: OptiPlex 790
  [  405.470690] sysfs: cannot create duplicate filename '/dev/char/10:54'

Always set vsock_device.minor to MISC_DYNAMIC_MINOR before we
register.

Subject: [PATCH 1617/1722] VSOCK: Drop bogus __init annotation from
 vsock_init_tables()

If gcc (e.g. 4.1.2) decides not to inline vsock_init_tables(), this will
cause a section mismatch:

WARNING: net/vmw_vsock/vsock.o(.text+0x1bc): Section mismatch in reference from the function __vsock_core_init() to the function .init.text:vsock_init_tables()
The function __vsock_core_init() references
the function __init vsock_init_tables().
This is often because __vsock_core_init lacks a __init
annotation or the annotation of vsock_init_tables is wrong.

This may cause crashes if VSOCKETS=y and VMWARE_VMCI_VSOCKETS=m.

The PTP Hardware Clock settime function in the e1000e driver
computes nanoseconds from a struct timespec. The code converts the
seconds field .tv_sec by multiplying it with NSEC_PER_SEC. However,
both operands are of type long, resulting in an unintended overflow.
The patch fixes the issue by using the helper function from time.h.

Subject: [PATCH 1622/1722] ixgbe: fix EICR write in ixgbe_msix_other

Previously, the ixgbe_msix_other was writing the full 32bits of the set
interrupts, instead of only the ones which the ixgbe_msix_other is
handling. This resulted in a loss of performance when the X540's PPS feature is
enabled due to sometimes clearing queue interrupts which resulted in the driver
not getting the interrupt for cleaning the q_vector rings often enough. The fix
is to simply mask the lower 16bits off so that this handler does not write them
in the EICR, which causes them to remain high and be properly handled by the
clean_rings interrupt routine as normal.

X540. MACC is used for X540.

In addition it removes a read of AUTOC and uses the stored value to force the
link up.

Subject: [PATCH 1626/1722] ixgbe: add mac type to the version in ethtool_regs

This patch adds the mac type to the version in ethtool_regs.

This will make it easier to check the mac type when dumping registers with
ethtool. The drawback of this is that older versions of ethtool will only
be able to dump in hex format for 82599 and above  when used with the updated
driver.

Subject: [PATCH 1630/1722] mwifiex: Do not kfree cmd buf while unregistering
 PCIe

All the command buffers are freed in mwifiex_free_cmd_buffer()
and hence there is no need to kfree the current command buffer
again. This might ends up freeing memory allocated by some other
kernel code.

Subject: [PATCH 1639/1722] genetlink: fix possible memory leak in
 genl_family_rcv_msg()

'attrbuf' is malloced in genl_family_rcv_msg() when family->maxattr &&
family->parallel_ops, thus should be freed before leaving from the error
handling cases, otherwise it will cause memory leak.

Introduced by commit def3117493eafd9dfa1f809d861e0031b2cc8a07
(genl: Allow concurrent genl callbacks.)

Add reference counting to the driver MAC registeration code. This would
be needed for cases where a mac is registered from more than once, e.g
when both the host and the VM driver register the same mac, the host
for mac spoof protection purposes and the VM for its regular needs.

 information

This patch add struct mlx4_vport_state where all the parameters related
to management of VFs port (virtual ports of the NIC eswitch) are kept.

The driver keeps an administrative and operational copy of the settings.
The current administrative copy becomes operational on the event of probing
a VF either on a VM or on the host.

Subject: [PATCH 1645/1722] net/mlx4: Add set VF default vlan ID and priority
 support

Add support to ndo_set_vf_vlan in the driver. Once this call is used the vport
is considered to be in VST mode. In this mode, the PPF driver configures
Ethernet QPs created by this VF to use this vlan id and priority. Currently
RoCE isn't supported on that mode.

The special values of VID=4095 or VID=0,UP=0 are considered as VGT.

Subject: [PATCH 1649/1722] ipvs: ip_vs_sip_fill_param() BUG: bad check of
 return value

The reason for this patch is crash in kmemdup
caused by returning from get_callid with uniialized
matchoff and matchlen.

Removing Zero check of matchlen since it's done by ct_sip_get_header()

Subject: [PATCH 1650/1722] bridge: Add fdb dst check during fdb update

Current bridge fdb update code does not seem to update the port
during fdb update. This patch adds a check for fdb dst (port)
change during fdb update. Also rearranges the call to
fdb_notify to send only one notification for create and update.

Changelog:
v2 - Change notify flag to bool

Subject: [PATCH 1653/1722] vxlan: fix byte order issues with NDA_PORT

The NDA_PORT attribute was added, but the author wasn't careful
about width (port is 16 bits), or byte order.  The attribute was
being dumped as 16 bits, but only 32 bit value would be accepted
when setting up a device. Also, the remote port is in network
byte order and was being compared with default port in host byte
order.

Subject: [PATCH 1654/1722] vxlan: source compatiablity with IFLA_VXLAN_GROUP
 (v2)

Source compatiability for build iproute2 was broken by:
  commit c7995c43facc6e5dea4de63fa9d283a337aabeb1
  Author: Atzm Watanabe <atzm@stratosphere.co.jp>
    vxlan: Allow setting destination to unicast address.

Since this commit has not made it upstream (still net-next),
and better to avoid gratitious changes to exported API's;
go back to original definition, and add a comment.

Subject: [PATCH 1655/1722] vxlan: compute source port in network byte order

Rather than computing source port and returning it in host order
then swapping later, go ahead and compute it in network order to
start with. Cleaner and less error prone.

Subject: [PATCH 1656/1722] vxlan: allow choosing destination port per vxlan

Allow configuring the default destination port on a per-device basis.
Adds new netlink paramater IFLA_VXLAN_PORT to allow setting destination
port when creating new vxlan.

Subject: [PATCH 1657/1722] selftests: psock_tpacket: fix status check

Testing like this for TP_STATUS_AVAILABLE clearly is a stupid bug
since it always returns true. Fix this by only checking for flags
where the kernel owns the packet and negate this result, since we
also could run into the non-zero status TP_STATUS_WRONG_FORMAT
and need to reclaim frames.

Subject: [PATCH 1658/1722] net: mac802154: comparision issue of type cast,
 finding by EXTRA_CFLAGS=-W

Change MAC802154_CHAN_NONE from ~(u8)0 to 0xff, or the comparison in
mac802154_wpan_xmit() for ``chan == MAC802154_CHAN_NONE'' will not
succeed.

This bug can be boiled down to ``u8 foo = 0xff; if (foo == ~(u8)0)
[...] else [...]'' where the condition will always take the else
branch.

Subject: [PATCH 1662/1722] packet_diag: disclose meminfo values

sk_rmem_alloc is disclosed via /proc/net/packet but not via netlink messages.
The goal is to have the same level of information.

Subject: [PATCH 1663/1722] sock_diag: allow to dump bpf filters

This patch allows to dump BPF filters attached to a socket with
SO_ATTACH_FILTER.
Note that we check CAP_SYS_ADMIN before allowing to dump this info.

For now, only AF_PACKET sockets use this feature.

Subject: [PATCH 1664/1722] atm: he: use mdelay instead of large udelay
 constants

ARM cannot handle udelay for more than 2 miliseconds, and
it is rather bad style to block the cpu for 16ms anyway,
so let's use msleep instead.

Subject: [PATCH 1665/1722] net: increase frag hash size

Increase fragmentation hash bucket size to 1024 from old 64 elems.

After we increased the frag mem limits commit c2a93660 (net: increase
fragment memory usage limits) the hash size of 64 elements is simply
too small.  Also considering the mem limit is per netns and the hash
table is shared for all netns.

For the embedded people, note that this increase will change the hash
table/array from using approx 1 Kbytes to 16 Kbytes.

Subject: [PATCH 1666/1722] ipv6: Kill ipv6 dependency of icmpv6_send().

Following patch adds icmp-registration module for ipv6.  It allows
ipv6 protocol to register icmp_sender which is used for sending
ipv6 icmp msgs.  This extra layer allows us to kill ipv6 dependency
for sending icmp packets.

This patch also fixes ip_tunnel compilation problem when ip_tunnel
is statically compiled in kernel but ipv6 is module

The socket buffer pool for the receive path is now gone.  It's existence
didn't make much difference (performance-wise) and the code is better off
without the spinlocks protecting it.

Subject: [PATCH 1669/1722] drivers: net: usb: pegasus: fix control urb
 submission

Pegasus driver used single callback for sync and async control URBs.
Special flags were employed to distinguish between both, but due to flawed
logic it didn't always work.  As a result of this change
[get|set]_registers() are now much simpler.  Async write is also leaner
and does not use single, statically allocated memory for usb_ctrlrequest,
which is another potential race when asynchronously submitting URBs.

Subject: [PATCH 1670/1722] hyperv: Fix a compiler warning in netvsc_send()

Fixed: warning: cast from pointer to integer of different size

The Hyper-V hosts always use 64 bit request id. The guests can have 32 or 64
bit pointers which equal to the ulong type size. So we cast it to ulong type.
And, assigning 32bit integer to 64 bit variable works fine.

The VMBus returns the same id in the completion packet. But the value has no
effect on the host side.

Subject: [PATCH 1673/1722] netfilter: ipset: Introduce extensions to elements
 in the core

Introduce extensions to elements in the core and prepare timeout as
the first one.

This patch also modifies the em_ipset classifier to use the new
extension struct layout.

Subject: [PATCH 1683/1722] netfilter: ipset: set match: add support to match
 the counters

The new revision of the set match supports to match the counters
and to suppress updating the counters at matching too.

At the set:list types, the updating of the subcounters can be
suppressed as well.

Subject: [PATCH 1685/1722] netfilter: move skb_gso_segment into
 nfnetlink_queue module

skb_gso_segment is expensive, so it would be nice if we could
avoid it in the future. However, userspace needs to be prepared
to receive larger-than-mtu-packets (which will also have incorrect
l3/l4 checksums), so we cannot simply remove it.

The plan is to add a per-queue feature flag that userspace can
set when binding the queue.

The problem is that in nf_queue, we only have a queue number,
not the queue context/configuration settings.

This patch should have no impact other than the skb_gso_segment
call now being in a function that has access to the queue config
data.

A new size attribute in nf_queue_entry is needed so
nfnetlink_queue can duplicate the entry of the gso skb
when segmenting the skb while also copying the route key.

The follow up patch adds switch to disable skb_gso_segment when
queue config says so.

Subject: [PATCH 1686/1722] netfilter: nfnetlink_queue: add skb info attribute

Once we allow userspace to receive gso/gro packets, userspace
needs to be able to determine when checksums appear to be
broken, but are not.

NFQA_SKB_CSUMNOTREADY means 'checksums will be fixed in kernel
later, pretend they are ok'.

NFQA_SKB_GSO could be used for statistics, or to determine when
packet size exceeds mtu.

Subject: [PATCH 1688/1722] sctp: Correct type and usage of sctp_end_cksum()

Change the type of the crc32 parameter of sctp_end_cksum()
from __be32 to __u32 to reflect that fact that it is passed
to cpu_to_le32().

There are five in-tree users of sctp_end_cksum().
The following four had warnings flagged by sparse which are
no longer present with this change.

net/netfilter/ipvs/ip_vs_proto_sctp.c:sctp_nat_csum()
net/netfilter/ipvs/ip_vs_proto_sctp.c:sctp_csum_check()
net/sctp/input.c:sctp_rcv_checksum()
net/sctp/output.c:sctp_packet_transmit()

The fifth user is net/netfilter/nf_nat_proto_sctp.c:sctp_manip_pkt().
It has been updated to pass a __u32 instead of a __be32,
the value in question was already calculated in cpu byte-order.

net/netfilter/nf_nat_proto_sctp.c:sctp_manip_pkt() has also
been updated to assign the return value of sctp_end_cksum()
directly to a variable of type __le32, matching the
type of the return value. Previously the return value
was assigned to a variable of type __be32 and then that variable
was finally assigned to another variable of type __le32.

Problems flagged by sparse.
Compile and sparse tested only.

Subject: [PATCH 1694/1722] tg3: shows HW time stamping support only if
 ptp_capable is present

Current tg3 shows hardware timestamping support for all devices
when that is true only for the hardware with PTP_CAPABLE flag
present.

Subject: [PATCH 1696/1722] tcp: reset timer after any SYNACK retransmit

Linux immediately returns SYNACK on (spurious) SYN retransmits, but
keeps the SYNACK timer running independently. Thus the timer may
fire right after the SYNACK retransmit and causes a SYN-SYNACK
cross-fire burst.

Adopt the fast retransmit/recovery idea in established state by
re-arming the SYNACK timer after the fast (SYNACK) retransmit. The
timer may fire late up to 500ms due to the current SYNACK timer wheel,
but it's OK to be conservative when network is congested. Eric's new
listener design should address this issue.

Subject: [PATCH 1698/1722] cxgb4: Support CPL_SGE_EGR_UPDATEs encapsulated in
 a CPL_FW4_MSG

Newer firmware can post CPL_SGE_EGR_UPDATE message encapsulated in a
CPL_FW4_MSG as follows

flit0 rss_header (if DropRSS == 0 in IQ context)
flit1 CPL_FW4_MSG cpl
flit2 rss_header w/opcode CPL_SGE_EGR_UPDATE
flit3 CPL_SGE_EGR_UPDATE cpl

So FW4_MSG CPLs with a newly created type of FW_TYPE_RSSCPL have the
CPL_SGE_EGR_UPDATE CPL message in flit 2 of the FW4_MSG. Firmware can still
post regular CPL_SGE_EGR_UPDATE messages, so the drivers need to handle
both.

This patch also writes a new parameter to firmware requesting encapsulated
EGR_UPDATE. This allows firmware with this support to not break older drivers.

Subject: [PATCH 1704/1722] unix/dgram: peek beyond 0-sized skbs

"77c1090 net: fix infinite loop in __skb_recv_datagram()" (v3.8) introduced a
regression:
After that commit, recv can no longer peek beyond a 0-sized skb in the queue.
__skb_recv_datagram() instead stops at the first skb with len == 0 and results
in the system call failing with -EFAULT via skb_copy_datagram_iovec().

When peeking at an offset with 0-sized skb(s), each one of those is received
only once, in sequence. The offset starts moving forward again after receiving
datagrams with len > 0.

 data in queue

Currently, peeking on a unix datagram socket with an offset larger than len of
the data in the sk receive queue returns immediately with bogus data. That's
because *off is not reset between each skb_queue_walk().

This patch fixes this so that the behavior is the same as peeking with no
offset on an empty queue: the caller blocks.

The commit f233a976ad15c3b8c54c0157f3c41d23f7514279 (tg3: shows
HW time stamping support only if ptp_capable is present) didn't
append hardware flags correctly. This patch fixes it.

Subject: [PATCH 1708/1722] 3c509.c: call SET_NETDEV_DEV for all device types
 (ISA/ISAPnP/EISA)

The venerable 3c509 driver only sets its device parent in one case, the ISAPnP one.
It does this with the SET_NETDEV_DEV function. It should register with the device
hierarchy in two additional cases: standard (non-PnP) ISA and EISA.

- Currently they appear here:
/sys/devices/virtual/net/eth0 (standard ISA)
/sys/devices/virtual/net/eth1 (EISA)

- Rather, they should instead be here:
/sys/devices/isa/3c509.0/net/eth0 (standard ISA)
/sys/devices/pci0000:00/0000:00:07.0/00:04/net/eth1 (EISA)

Tested on ISA and EISA boards.

Ether MAHR/MALR registers (there's no storage provided for the Ether MAC address

Subject: [PATCH 1710/1722] drivers: net: cpsw: fix kernel warn on cpsw irq
 enable

With the commit a11fbba (net/cpsw: fix irq_disable() with threaded interrupts)
from Sebastian Siewior, a kernel warning is generated as below. This warning
is generated as the irq_enabled is not initialized for the primary interface
and in probe it is initialized for the second interface. This patch moves
irq_enabled initialization from second interface to primary interface.

Bridge can crash while trying to send topology change packet.
This happens if root port can't be found. This was reported by user
but currently unable to reproduce it easily. The STP conditions that cause
this are not known yet, but the problem doesn't have to be fatal.

This reverts commit d2d2d87dfd1a25ee270994c5b9e3eb4690428d32
("bnx2x: allow nvram test to run when device is down").

Since it makes access to the device in D3 state possible.
More work is required to make sure device is not set to D3
during ifdown. Until this is done the nvram-test should simply
exit if device is down like it did before.

This resulted from my commit ca99ca14c which introduced a mutex_trylock
operation in a path that could execute in interrupt context.  When mutex
debugging is enabled, the above warns the user when we are in fact
exectuting in interrupt context
interrupt context.

After some discussion, It seems that a semaphore is the proper mechanism to use
here.  While mutexes are defined to be unusable in interrupt context, no such
condition exists for semaphores (save for the fact that the non blocking api
calls, like up and down_trylock must be used when in irq context).

Subject: [PATCH 1717/1722] netlink: kconfig: move mmap i/o into netlink
 kconfig

Currently, in menuconfig, Netlink's new mmaped IO is the very first
entry under the ``Networking support'' item and comes even before
``Networking options'':

  [ ]   Netlink: mmaped IO
  Networking options  --->
  ...

Lets move this into ``Networking options'' under netlink's Kconfig,
since this might be more appropriate. Introduced by commit ccdfcc398
(``netlink: mmaped netlink: ring setup'').

When the bnx2x driver reads the port configuration - mask irrelevant bits.

Without this change, the unintended bits may cause the driver to needlessly
toggle the link, as a comparison in the link flap avoidance flow will show
that the old link did not advertise the same capabilities and thus cannot
be retained.

Subject: [PATCH 1721/1722] af_unix: fix a fatal race with bit fields

Using bit fields is dangerous on ppc64/sparc64, as the compiler [1]
uses 64bit instructions to manipulate them.
If the 64bit word includes any atomic_t or spinlock_t, we can lose
critical concurrent changes.

This is happening in af_unix, where unix_sk(sk)->gc_candidate/
gc_maybe_cycle/lock share the same 64bit word.

This leads to fatal deadlock, as one/several cpus spin forever
on a spinlock that will never be available again.

A safer way would be to use a long to store flags.
This way we are sure compiler/arch wont do bad things.

As we own unix_gc_lock spinlock when clearing or setting bits,
we can use the non atomic __set_bit()/__clear_bit().

recursion_level can share the same 64bit location with the spinlock,
as it is set only with this spinlock held.

[1] bug fixed in gcc-4.8.0 :
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52080
