Subject: [PATCH 0003/1958] Bluetooth: hidp: Stop I/O on shutdown

Current hidp driver purges the in/out queue on HID shutdown, but does
not prevent further I/O. If a driver uses hidp_output_raw_report or
hidp_get_raw_report during shutdown, the driver hangs for 5 or 10
seconds per call until it gets a timeout.
That is, if the output queue of an HID driver has 10 messages pending,
it will take 50s until hid_destroy_device() will return. The
hidp_session_sem semaphore is held during shutdown so no other HID
device may be added/removed during this time.

This patch makes hidp_output_raw_report and hidp_get_raw_report fail if
session->terminate is true. Also hidp_session will wakeup all current
calls to these functions to cancel the current operations.

We already purge the current I/O queues on hidp_stop(), so this data loss
does not change the behaviour of the HID drivers.

hidp_get_connection() makes more sense because we hold a reference to the
connection inside this function.

Subject: [PATCH 0013/1958] wl12xx: replace wl->mac_addr with vif->addr

The mac address of the interface already exists in vif->addr.
Use it instead of wl->mac_addr.

It seems that due to some fw bug, we still need to set nvs->mac
to the actual mac addresss, otherwise the fw doesn't function
well (e.g. can't get dhcp address).
Thus, use wl->mac_addr for this purpose, and don't delete it yet.

From 92c77c734f958474ac73af670834bc32cb833e54 Mon Sep 17 00:00:00 2001
From: Eliad Peller <eliad@wizery.com>
Date: Wed, 5 Oct 2011 11:55:40 +0200
Subject: [PATCH 0014/1958] wl12xx: start reworking the init sequence

Split the init sequence into common commands (non role-specific)
and role-specific commands.

We still need to call the common commands only on add_interface()
(rather than on start()) as the fw must get the mac address
when uploading the nvs.

Future patches will refactor the init sequence further more.

From 87fbcb0f8c5c8fd57a4e3e7e638977c04ce1e0ca Mon Sep 17 00:00:00 2001
From: Eliad Peller <eliad@wizery.com>
Date: Wed, 5 Oct 2011 11:55:41 +0200
Subject: [PATCH 0015/1958] wl12xx: define wl12xx_vif

Define a per-vif data struct.
This struct holds all the vif-specifc data, which is
currently being hold by the global wl struct.

Start by moving the basic_rate_set field into it.

NOTE: in order to make the patches a bit smaller, start by
using wl->vif in some functions, instead of changing all
the function prototypes at once. finally, wl->vif will be
removed altogether.

Subject: [PATCH 0028/1958] wl12xx: move ap_global_hlid and ap_bcast_hlid into
 wlvif

move ap_global_hlid and ap_bcast_hlid into the per-interface
data, rather than being global.

Subject: [PATCH 0039/1958] wl12xx: move ap_hlid_map into wlvif.ap

Add wlvif->links_map bitmap to represent all the links
allocated for this vif.

AP vif also has a sta_hlid_map bitmap, which represents
the links stations connected to it (sta_hlid_bitmap is
a subset of wlvif->links_map, which itself is a subset
of the global wl->links_map)

Subject: [PATCH 0041/1958] Bluetooth: btusb: also be quiet when suspending

usb_submit_urb() returns -ENODEV when a usb device is disconnected. In
commit 4935f1c164ac528dff3538f97953b385ba500710 ("Bluetooth: btusb: be
quiet on device disconnect") I stopped treating that return as an error
in the three btusb_*_complete() functions.

It turns out btusb_send_frame() generates a similar error if the system
is suspended while the bluetooth usb device is enabled. The sensible
thing to do here seems to be to treat -ENODEV (and -EPERM) just like the
btusb_*_complete() functions now do.

Subject: [PATCH 0042/1958] Bluetooth: btusb: hide more usb_submit_urb errors

There are still three calls of usb_submit_urb() that will print errors
if those calls return -EPERM or -ENODEV. I have never triggered these,
so I'm not sure when these return values might be seen. It still makes
sense to be silent if these occur (since "urb is being killed" and
"device got disconnected" aren't things to worry about).

Subject: [PATCH 0043/1958] wl12xx: refactor fw init into a new function

The fw boot and initialization currently happens inside the
add_interface() callback. This is wrong, as add_interface is
called for each new vif. However, we due to some fw limitation
(we have to know the actual mac address on boot), we can't
completely move it into the start() callback.

Until the fw will be fixed, refactor the fw init into
a new function, and call it from add_interface()

Subject: [PATCH 0045/1958] wl12xx: unify STA and AP tx_queue mechanism

Make sta use the global wl->links[hlid].tx_queue (by
considering its links map) instead of wl->tx_queue,
and then unify the tx and tx_reset flows for the
various vifs.

Subject: [PATCH 0046/1958] wl12xx: move some functions from remove_interface()
 to stop()

Leave only vif-specific deinit stuff in remove_interface().
Move the global deinit (including power_off) to stop().

Subject: [PATCH 0049/1958] wl12xx: support multiple vifs in the tx path

Pass the wlvif associated with each skb as param.

Note that dummy packet doesn't belong to any
particular vif, so we pass NULL in this case.

(Note that this is a global configuration, so if the
device is already configured according to our policy,
we don't have to configure it again)

Subject: [PATCH 0051/1958] wl12xx: make event handling support multirole

Some events don't indicate the role they are intended for.
In these cases, iterate through all the relevant vifs,
and pass the event to each one of them.

This is only a workaround. future fw releases should indicate
the relevant role_id for such events.

Subject: [PATCH 0052/1958] wl12xx: move tx_security_seq into wlvif

The last security seq num has to be saved across reconfigs.
Add a new "persistent" struct into wlvif, which won't get
deleted on wl12xx_init_vif_data()

From 9eb599e9c62dcfd4efece1936c385381b366b684 Mon Sep 17 00:00:00 2001
From: Eliad Peller <eliad@wizery.com>
Date: Mon, 10 Oct 2011 10:12:59 +0200
Subject: [PATCH 0053/1958] wl12xx: rearm rx streaming per vif

Currently, the rx streaming doesn't support multi-vif
(the actual wlvif is taken from wl->vif, and the management
is global).

Make the rx streaming timers/works per-vif, and pass the
the actual vif as param.

Subject: [PATCH 0063/1958] wl12xx: add band field to wlvif

add band field into the per-interface data.

mac80211 configures some values (e.g. band, channel)
globally, while we configure them per-interface.

In order to make it easier to keep track of the
configured value for each value while keeping sync
with mac80211, save these values both globally
and per-vif.

From 61f845f4f441a90e5328a78c6c4e0646d99fc2f0 Mon Sep 17 00:00:00 2001
From: Eliad Peller <eliad@wizery.com>
Date: Mon, 10 Oct 2011 10:13:10 +0200
Subject: [PATCH 0064/1958] wl12xx: add channel field to wlvif

add channel into the per-interface data.

mac80211 configures some values (e.g. band, channel)
globally, while we configure them per-interface.

In order to make it easier to keep track of the
configured value for each value while keeping sync
with mac80211, save these values both globally
and per-vif.

Subject: [PATCH 0065/1958] wl12xx: add power_level field to wlvif

move power_level into the per-interface data.

mac80211 configures some values (e.g. band, channel)
globally, while we configure them per-interface.

In order to make it easier to keep track of the
configured value for each value while keeping sync
with mac80211, save these values both globally
and per-vif.

Subject: [PATCH 0067/1958] wl12xx: replace all remaining wl->vif references

wl->vif is appropriate only when a single vif is being used.
Instead, pass wlvif as parameter or iterate through all
the vifs (e.g. when a global configuration was changed)

Leave wl->vif only to determine whether a vif was already
added (this check will be removed as well after both the
driver and fw will support multiple vifs)

Currently, a single vif might starve all the other vifs.
Save the last vif we dequeued a packet from, and continue
with the following one using a round-robin policy.

Subject: [PATCH 0072/1958] wl12xx: remove sdio_test module

This module has been causing more trouble than being useful.  It only
tests the SDIO speed by connecting to the wl12xx chip and does some
throughput calculations.  It is an ugly quick hack and, if we really
want to have it as part of wl12xx we need to clean it up and implement
it properly.

A tarball of the code has been created and posted here, with some
instructions:

Subject: [PATCH 0073/1958] wl12xx: add an sdio glue struct to keep wl and
 device side-by-side

In order to fully abstract the bus, we need to save the device
structure *beside* wl1271, instead of inside it.

This will help re-structuring the driver so that we avoid the
duplicated code in the bus modules.

Subject: [PATCH 0081/1958] wl12xx: move debugging definitions to a separate
 file

Separate the debugging macros and other definitions to a new debug.h
file.  This is be needed because the sdio and spi modules don't need
to depend on the wl12xx module anymore, but still need to include
wl12xx.h.  Currently they do depend on it, because of the debugging
global that wl12xx exports.  A future patch will remove this
dependency.

Subject: [PATCH 0082/1958] wl12xx: sdio: use dev_dbg instead of wl1271_debug

To prevent a useless dependency between the sdio module and the wl12xx
module, we need to replace the wl1271_debug macros (and friends) for
dev_dbg and other equivalents.

At the same time, remove the SDIO data hexdump, since this produces
way too much data and is not particularly useful.  There's not
print_hex_dump() equivalent for dynamic debug, so it's hard to control
when the dumps are printed out.

Subject: [PATCH 0083/1958] wl12xx: spi: use dev_err instead of wl1271_error

To prevent a useless dependency between the spi module and the wl12xx
module, we need to replace the wl1271_error macros with dev_err.

At the same time, remove the SPI data hexdump, since this produces way
too much data and is not particularly useful.  There's no
print_hex_dump() equivalent for dynamic debug, so it's hard to control
when the dumps are printed out.

Subject: [PATCH 0090/1958] wl12xx: use the same plat dev name for both SPI and
 SDIO

There's no need to have the bus name included in the platform device
name that we create.  The core driver doesn't need to know about the
type of bus it uses.  Any differences between the buses that need to
be handled differently in the core, can be passed in the platform data
(as the pwr_in_suspend boolean does).

Use "wl12xx" for the device name in both bus drivers.  Rename the
platform driver name to "wl12xx_driver", just to differentiate from
the platform device names.

Subject: [PATCH 0092/1958] wl12xx: handle injected packets

Injected packets are sent with no vif, causing the wl12xx
to NULL-dereference in multiple places.

Furthermore, injected packets are currently not sent at all,
as system_hlid doesn't belong to any specific role, so
wl1271_skb_dequeue() never return its packets.

Handle both these problems.

Subject: [PATCH 0093/1958] Bluetooth: EWS: extended window size option support

Adds support for extended window size (EWS) config option. We enable EWS
feature in L2CAP Info RSP when hs enabled. EWS option is included in L2CAP
Config Req if tx_win (which is set via socket) bigger then standard default
value (63) && hs enabled && remote side supports EWS feature.

Using EWS selects extended control field in L2CAP.

Code partly based on Qualcomm and Atheros patches sent upstream a year ago.

Subject: [PATCH 0108/1958] Bluetooth: Fix hci core device initialization

We must not call device_del() if we didn't use device_add(). See module.c
for comments on that. Therefore, we need to call device_initialize() when
allocating the hci device and later device_add() instead of
device_register().

This also fixes a bug when hci_register_dev() failed and we call
hci_free_dev() without a valid core device. hci_free_dev() segfaults while
calling put_device() on invalid memory.

We already do this with hci_conn connections (hci_conn_init_sysfs()) so
they do not need to be fixed.

Subject: [PATCH 0109/1958] Bluetooth: Rename sysfs un/register to add/del

As we introduced hci_init_sysfs() we should also rename
hci_register_sysfs() and hci_unregister_sysfs() to hci_add_sysfs() and
hci_del_sysfs() like we do with hci_conn_add/del_sysfs(). It looks more
consistent now.

Subject: [PATCH 0123/1958] Bluetooth: Ignore hci_unregister_dev return value

Make all bluetooth drivers ignore the return value of hci_unregister_dev as it
always returns 0. In the next step, hci_unregister_dev can be modified to return
void.
Some of the drivers already ignore the return value (including btusb), hence,
this will increase consitency in the bluetooth drivers.

Subject: [PATCH 0130/1958] Bluetooth: replace list_for_each with
 list_for_each_entry whenever possible

When all items in the list have the same type there is no much of a point
to use list_for_each except if you want to use the list pointer itself.

Subject: [PATCH 0133/1958] Bluetooth: Fix command complete/status for
 discovery commands

This patch adds the necessary code to send proper command status or
command complete events to the start/stop discovery management commands.
Before this patch these events were completely missing.

Subject: [PATCH 0134/1958] Bluetooth: rfcomm: Fix sleep in invalid context in
 rfcomm_security_cfm

This was triggered by turning off encryption on ACL link when rfcomm
was using high security. rfcomm_security_cfm (which is called from rx
task) was closing DLC and this involves sending disconnect message
(and locking socket).

Move closing DLC to rfcomm_process_dlcs and only flag DLC for closure
in rfcomm_security_cfm.

BUG: sleeping function called from invalid context at net/core/sock.c:2032

Subject: [PATCH 0135/1958] Bluetooth: Increase HCI reset timeout in
 hci_dev_do_close

I've noticed that my CSR usb dongle was not working if it was plugged in when
PC was booting. It looks like I get two HCI reset command complete events (see
hcidump logs below).
The root cause is reset called from off_timer. Timeout for this reset to
complete is set to 250ms and my bt dongle requires more time for replying with
command complete event. After that, chip seems to reply with reset command
complete event for next non-reset command.

Attached patch increase mentioned timeout to HCI_INIT_TIMEOUT, this value is
already used for timeouting hci_reset_req in hci_dev_reset().

This might also be related to BT not working after suspend that was reported
here some time ago.

Hcidump log:

Subject: [PATCH 0138/1958] Bluetooth: bcm203x: Fix race condition on
 disconnect

When disconnecting a bcm203x device we kill and destroy the usb-urb, however,
there might still be a pending work-structure which resubmits the now invalid
urb. To avoid this race condition, we simply set a shutdown-flag and
synchronously kill the worker first.

This also adds a comment to all schedule_work()s, as it is really not clear
that they are used as replacement for short timers (which can be seen in the git
history).

When loading the usb-configuration we do not signal the end of configuration on
memory allocation error. This patch moves the memory allocation to the top so
every error path uses "goto error" now to correctly send the usb-ctrl message
when detecting some error.

This also replaces GFP_ATOMIC with GFP_KERNEL as we are allowed to sleep here.

Subject: [PATCH 0141/1958] Bluetooth: hidp: Fix module reference cleanup

Calling module_put(THIS_MODULE) is *never* safe when we cannot go sure that we
own at least two references. This is because the call may unload our module
before it returns and then the "return" will jump into invalid memory.

Gladly, module.h provides a wrapper for kthread-users: module_put_and_exit().
This puts our module and then exits the kthread without returning to the module.

This patch fixes the hidp kthread to use this wrapper instead of manually
freeing its own reference. See nfsd or lockd for other kthreads using this.

Calling __module_get() inside the kthread is safe as the hidp module will always
wait until the kthread sets "waiting_for_startup" to 0.

Subject: [PATCH 0144/1958] Bluetooth: handle priority change within quote

The quote is calculated based on the first buffer in the queue so if the
priority changes to something lower than the priority of the first skb
the quote needs to be recalculated.

Subject: [PATCH 0145/1958] Bluetooth: recalculate priorities when channels are
 starving

To avoid starvation the priority is recalculated so that the starving
channels are promoted to HCI_PRIO_MAX - 1 (6).

HCI_PRIO_MAX (7) is considered special, because it requires CAP_NET_ADMIN
capability which can be used to provide more guaranties, so it is not used
when promoting.

Subject: [PATCH 0155/1958] Bluetooth: Add signal handlers for channel moves

AMP channels can be moved between BR/EDR and AMP controllers using a
sequence of signals. Every attempted channel move involves a series of
four signals:

   Move Initiator                 Move Responder
        |                                 |
        |       Move Channel Request      |
        |  ---------------------------->  |
        |                                 |
        |       Move Channel Response     |
        |  <----------------------------  |
        |                                 |
        |       Move Channel Confirm      |
        |  ---------------------------->  |
        |                                 |
        |  Move Channel Confirm Response  |
	|  <----------------------------  |

All four signals are sent even if the move fails.

Subject: [PATCH 0160/1958] wl12xx: couple role_start_dev with roc

Device role is always started along with ROC.
Couple them together by introducing new wl12xx_start_dev
and wl12xx_stop_dev functions.

By using these functions, we solve a bug that occured during
channel switch - we started the dev role on one channel, and
ROCed on a different one.

Subject: [PATCH 0161/1958] wl12xx: reconfigure rate policies on

The rate policies are configured only after association,
resulting in auth req being sent in wrong rates.

Reconfigure rate policies on bitrate mask change.

Subject: [PATCH 0162/1958] wl12xx: keep beacon-filtering enabled during STA

Enable beacon filtering on STA init, and don't disable it when entering
active mode. Otherwise dynamic-PS supports means we receive beacons from
the current AP during any Tx/Rx performed by the driver.

Subject: [PATCH 0164/1958] wl12xx: clear wl->vif on remove_interface

wl->vif should be cleared on remove_interface()
(rather than on stop()) even when only a single
vif is supported, because during vif mode change
stop() might not get called (e.g. because of
monitor interface existence)

Subject: [PATCH 0165/1958] wl12xx: change blocksize alignment quirk to
 negative

SDIO blocksize alignment support is now the rule, not the exception.
To simplify the code in patches to come, invert the meaning of the
quirk to be negative (ie. the quirk is set if the device does _not_
support blocksize alignment).

Subject: [PATCH 0166/1958] wl12xx: use the same SDIO block size for all
 different chips

The sdio driver uses a block size of 512 bytes by default.  With our
card, this doesn't work correctly because it sets the block size FBR
in the chip too early (ie. before the chip is powered on).  Thus, if
we don't set it explicitly, block mode remains disabled in the chip.
If we try to send more data than fits in one block, the sdio driver
will split it into separate blocks before sending to the chip.  This
causes problems because the chip is not expecting multiple blocks.

At the moment this is not a problem, because we use chunks of 512
bytes for firmware upload and the data is always sent in byte mode.
In the next patch, we will change the chunk size to a bigger value, so
this patch is a preparation for that.

Subject: [PATCH 0167/1958] wl12xx: increase firmware upload chunk size

The chunk size used during firmware upload was set to 512, which is
the size of a single SDIO block (or two).  This is very inneficient
because we send one or two blocks only per SDIO transaction and don't
get the full benefits of sdio block transfers.

This patch increases the chunk size to 16K.  This more than doubles
the transfer speed both in wl127x and wl128x chips, with greater
impact on the latter:

wl127x:   512 bytes chunk -> ~132ms
        16384 bytes chunk ->  ~57ms
wl128x:   512 bytes chunk -> ~216ms
        16384 bytes chunk ->  ~37ms

Subject: [PATCH 0175/1958] Bluetooth: Create hci_cancel_inquiry()

This patch adds a function to hci_core to cancel an ongoing inquiry.

According to the Bluetooth spec, the inquiry cancel command should
only be issued after the inquiry command has been issued, a command
status event has been received for the inquiry command, and before
the inquiry complete event occurs.

As HCI_INQUIRY flag is only set just after an inquiry command status
event occurs and it is cleared just after an inquiry complete event
occurs, the inquiry cancel command should be issued only if HCI_INQUIRY
flag is set.

Additionally, cancel inquiry related code from stop_discovery() were
replaced by a hci_cancel_inquiry() call.

Subject: [PATCH 0176/1958] Bluetooth: Periodic Inquiry and Discovery

By using periodic inquiry command we're not able to detect correctly
when the controller has started inquiry.

Today we have this workaround in inquiry result event handler
to set the HCI_INQUIRY flag when it sees the first inquiry result
event. This workaround isn't enough because the device may be
performing an inquiry but the HCI_INQUIRY flag is not set. For
instance, if there is no device in range, no inquiry result event
is generated, consequently, the HCI_INQUIRY flags isn't set when
it should so.

We rely on HCI_INQUIRY flag to implement the discovery procedure
properly. So, as we aren't able to clear/set the HCI_INQUIRY flag
in a reliable manner, periodic inquiry events shouldn't change
the HCI_INQUIRY flag.

Thus, due to that issue and in order to keep compatibility with
userspace, periodic inquiry events shouldn't send mgmt discovering
events.

In future, we might track if periodic inquiry is enabled or not.
By tracking this state we'll be able to do some improvements in
Discovery such as failing MGMT_OP_START_DISCOVERY command in case
periodic inquiry is on. We can also send no mgmt_device_found
event if periodic inquiry is on.

Subject: [PATCH 0183/1958] Bluetooth: Add address type fields to mgmt messages
 that need them

This patch adds address type info (typically BR/EDR vs LE) to management
messages that need this. This also ensures conformance to the latest
management API specification.

Subject: [PATCH 0184/1958] net: better pcpu data alignment

Tunnels can force an alignment of their percpu data to reduce number of
cache lines used in fast path, or read in .ndo_get_stats()

percpu_alloc() is a very fine grained allocator, so any small hole will
be used anyway.

Subject: [PATCH 0187/1958] sweep the floors and convert some .get_drvinfo
 routines to strlcpy

Per the mention made by Ben Hutchings that strlcpy is now the preferred
string copy routine for a .get_drvinfo routine, do a bit of floor
sweeping and convert some of the as-yet unconverted ethernet drivers to
it.

Subject: [PATCH 0188/1958] net: make ipv6 bind honour freebind
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This makes native ipv6 bind follow the precedent set by:
  - native ipv4 bind behaviour
  - dual stack ipv4-mapped ipv6 bind behaviour.

This does allow an unpriviledged process to spoof its source IPv6
address, just like it currently can spoof its source IPv4 address
(for example when using UDP).

Subject: [PATCH 0192/1958] iwlagn: remove unnecessary type for tracing
 operations

The device tracing routines only use the priv pointer as an opaque
value.  Change from a typed iwl_priv pointer to a null pointer and
eliminate the need to include iwl_priv.h.  CMD_ASYNC is defined in
iwl_shared.h which is the only reason it is included.

mac80211 calls ieee80211_set_wmm_default (which in turn
calls drv_conf_tx()) for every new interface, including
"internal" ones (e.g. monitor interface, which the low-level
driver doesn't know about).

Limit this call only to valid interfaces.

Wifi drivers can have up to 6 keys but the rndis_wlan only has 4 so
it needs to have its own checks to make sure we don't go out of
bounds.  The add_key() function already checks but I added some
checks to del_key() and set_default_key().

Subject: [PATCH 0199/1958] iwmc3200wifi: add some more range checks

My previous patch added a check to get_key() but missed a couple
other places which need range checks.

The problem here is that wifi drivers have different numbers of keys.
The lower levels assume that they can have up to 4 default keys and
2 management keys but this driver only has the default keys so we
could go past the end of the ->keys[] array.

Subject: [PATCH 0203/1958] brcm80211: smac: drop "40MHz intolerant" flag from
 HT capability info

The brcmsmac driver registered with mac80211 with HT capability info
set to 40MHz intolerant. This cause any other station on the channel
to be forced to use 20MHz. This flag has been removed.

Subject: [PATCH 0207/1958] brcm80211: fmac: changed two scan related
 structures

struct brcmf_scan_results contained a 1 element array, but in reality
the number of scan results can be 0 or more, as indicated by the
count field in the same struct. Array has be redefined to be 0 elements
length to indicate the array is purely for reference.

In case the hardware crashes, a reinitialization internal to the driver
was performed. Since Mac80211 must be in the know of such an event as
well, ieee80211_restart_hw() is now called.

Subject: [PATCH 0210/1958] brcm80211: smac: avoid sprom endianess conversions
 for crc8 check

The data from the sprom consists of u16 values stored in little
endian notation over which a crc8 was determined. To validate this
the buffer needed to be converted for big-endian systems. Reading
the sprom data is now done per byte so conversion is only done
after a successful crc8 check.

In main.c a couple of functions were not static although they
were only locally used. Sparse gave warnings on them and these
functions have been made static.

Subject: [PATCH 0212/1958] brcm80211: smac: remove phy api bypass in rate.h

Obviously the phy api should be used to interface with the phy. In
rate.h a table within phy was accessed directly by declaring the
table extern in rate.h itself. This patch fixes this using the
provided api function to obtain the table reference. This bypass
was found by a sparse warning on the table not being defined static.

Subject: [PATCH 0216/1958] brcm80211: fmac: use sk_buff list for handling
 frames in receive path

The functions in the receive patch of the fullmac now use sk_buff
list and skb_queue_xx() functions instead of dealing with list pointers
in the sk_buff directly.

Subject: [PATCH 0220/1958] brcm80211: smac: removed MPC related code

The chip init sequence enables MPC (Minimum Power Consumption), but the
driver disables it after that. As there are no interfaces to enable this
mode the related code is unused (member variable wlc->mpc is false).

Subject: [PATCH 0222/1958] brcm80211: smac: removed down-on-watchdog MPC
 functionality

Softmac would bring its interface down on a certain Minimum Power Save
related condition, without Mac80211 intervention. Because Mac80211 should
be the only party initiating interfaces going up and down, this functionality
has been removed. All notions of 'MPC' have been removed in the code as
well.

Subject: [PATCH 0223/1958] brcm80211: smac: removed down-on-rf-kill
 functionality

Softmac would bring its interface down on an RF kill switch condition,
without Mac80211 intervention. Because Mac80211 should be the only party
initiating interfaces going up and down, this functionality has been
removed.

Subject: [PATCH 0224/1958] brcm80211: smac: bugfix for tx mute in
 brcms_b_init()

Transmit can only be muted if the mac core is enabled. When brcms_b_init()
is called, the mac core is suspended. Brcms_b_init() calls a transmit mute
function that requires an enabled mac core. This code path is never taken,
but would have been taken in subsequent patches.

Subject: [PATCH 0225/1958] brcm80211: smac: fixed inconsistency in transmit
 mute

Transmit was muted in two ways: full mute and a partial mute called
'pre ism cac time' mute. But, this 'pre ism cac time' mute was done at
one place in the code (when tx_mute == false), and overridden later
on in another place in code.

To fix this, the 'pre ism cac time' mute has been replaced by a non
mute.

Subject: [PATCH 0226/1958] brcm80211: smac: modified Mac80211 callback
 interface

Upon ops_start(), a Mac80211 driver should enable receive functionality to
support monitor mode. Also, upon ops_stop(), it should disable rx.

Driver did not follow this rule so code has been changed.

Subject: [PATCH 0227/1958] brcm80211: smac: mute transmit on ops_start

Monitor mode functionality (not functional yet) requires transmit to be
muted after ops_start() is called, transmit is unmuted when the first
interface is added.

 frames in receive path

In the receive path the frames are obtained from the dma using
multiple sk_buff that were linked using the skb next pointer.
This has been changed and it now used sk_buff lists and skb_queue
functions instead.

Subject: [PATCH 0234/1958] brcm80211: smac: change buffer endianess convert
 function interface

The buffer endianess conversion functions in srom.c had a size
argument giving number of bytes but the function converts words.
Providing the number of words to the function is more sensible
so that is done in this patch.

Subject: [PATCH 0235/1958] nl80211: clean up genlmsg_end uses

genlmsg_end() cannot fail, it just returns the length
of the message. Thus, error handling for it is useless.
While removing it, I also noticed a useless variable
and removed this it as well.

Subject: [PATCH 0236/1958] mac80211: support adding IV-room in the skb for
 CCMP keys

Some cards can generate CCMP IVs in HW, but require the space for the IV
to be pre-allocated in the frame at the correct offset. Add a key flag
that allows us to achieve this.

Subject: [PATCH 0239/1958] ath9k: Add btcoex profile management support for
 AR9462

AR9462 chips have the capabilities to provoide bluetooth
profile information. For non-AR9462 btcoex chips, the BT
priority traffic was identified by periodically polling
the respective registers and updated dutycycle, stomptype,
etc. As AR9462 chip offers the BT profile informations,
let us make use of that to update aggregation limit,
dutycycle, stomptype and wieghtages.

Subject: [PATCH 0246/1958] sch_choke: use skb_header_pointer()

Remove the assumption that skb_get_rxhash() makes IP header and ports
linear, and use skb_header_pointer() instead in choke_match_flow()

This permits __skb_get_rxhash() to use skb_header_pointer() eventually.

Subject: [PATCH 0247/1958] net: rename sk_clone to sk_clone_lock

Make clear that sk_clone() and inet_csk_clone() return a locked socket.

Add _lock() prefix and kerneldoc.

Subject: [PATCH 0248/1958] Bluetooth: Pass full hci_dev struct to mgmt
 callbacks

The current global pending command list in mgmt.c is racy. Possibly the
simplest way to fix it is to have per-hci dev lists instead of a global
one (all commands that need a pending struct are hci_dev specific).
This way the list can be protected using the already existing per-hci
dev lock. To enable this refactoring the first thing that needs to be
done is to ensure that the mgmt functions have access to the hci_dev
struct (instead of just the dev id).

Subject: [PATCH 0249/1958] Bluetooth: Move pending management command list
 into struct hci_dev

This patch moves the pending management command list (previously global
to mgmt.c) into struct hci_dev. This makes it possible to do proper
locking when accessing it (through the existing hci_dev locks) and
thereby avoid race conditions.

Now that the pending commands are within struct hci_dev we can properly
control access to them throught the hci_dev locking mechanism.

Subject: [PATCH 0251/1958] Bluetooth: Fix cancel_delayed_work_sync usage with
 locks

The cancel_delayed_work_sync function should not be used if we hold any
locks. Luckily all places where this is the case it is also safe to use
the non-sync version.

Subject: [PATCH 0255/1958] mac80211: handle HT PHY BSS membership selector
 value correctly

802.11n-2009 extends the supported rates element with a
magic value which can be used to prevent legacy stations
from joining the BSS.

However, this magic value is not a rate like the others
and the magic can simply be ignored/skipped at this late
stage.

Subject: [PATCH 0256/1958] cfg80211: annotate cfg80211_inform_bss

This function returns a referenced BSS struct
(or NULL), annotate with __must_check. It seems
that a lot of drivers get this completely wrong
and leak all BSS structs as a result.

Subject: [PATCH 0268/1958] net: add wireless TX status socket option

The 802.1X EAPOL handshake hostapd does requires
knowing whether the frame was ack'ed by the peer.
Currently, we fudge this pretty badly by not even
transmitting the frame as a normal data frame but
injecting it with radiotap and getting the status
out of radiotap monitor as well. This is rather
complex, confuses users (mon.wlan0 presence) and
doesn't work with all hardware.

To get rid of that hack, introduce a real wifi TX
status option for data frame transmissions.

This works similar to the existing TX timestamping
in that it reflects the SKB back to the socket's
error queue with a SCM_WIFI_STATUS cmsg that has
an int indicating ACK status (0/1).

Since it is possible that at some point we will
want to have TX timestamping and wifi status in a
single errqueue SKB (there's little point in not
doing that), redefine SO_EE_ORIGIN_TIMESTAMPING
to SO_EE_ORIGIN_TXSTATUS which can collect more
than just the timestamp; keep the old constant
as an alias of course. Currently the internal APIs
don't make that possible, but it wouldn't be hard
to split them up in a way that makes it possible.

Thanks to Neil Horman for helping me figure out
the functions that add the control messages.

Subject: [PATCH 0269/1958] mac80211: verify virtual interfaces in driver API

The driver is never informed about monitor or
AP_VLAN interfaces, so whenever we pass those
to it later this is a bug. Verify we don't as
there are some cases where this could happen.

Subject: [PATCH 0271/1958] mac80211: Avoid filling up mesh preq queue with
 redundant requests

Don't accept redundant PREQs for a given destination. This fixes a
problem under high load:

kernel: [20386.250913] mesh_queue_preq: 235 callbacks suppressed
kernel: [20386.253335] Mesh HWMP (mesh0): PREQ node queue full
kernel: [20386.253352] Mesh HWMP (mesh0): PREQ node queue full
(...)

The 802.11s protocol has a provision to limit the rate of path requests
(PREQs) are transmitted (dot11MeshHWMPpreqMinInterval) but there was no
limit on the rate at which PREQs were being queued up.  There is a valid
reason for queuing PREQs: this way we can even out PREQ bursts.  But
queueing multiple PREQs for the same destination is useless.

Subject: [PATCH 0272/1958] ipv4: reduce percpu needs for icmpmsg mibs

Reading /proc/net/snmp on a machine with a lot of cpus is very expensive
(can be ~88000 us).

This is because ICMPMSG MIB uses 4096 bytes per cpu, and folding values
for all possible cpus can read 16 Mbytes of memory.

ICMP messages are not considered as fast path on a typical server, and
eventually few cpus handle them anyway. We can afford an atomic
operation instead of using percpu data.

This saves 4096 bytes per cpu and per network namespace.

Subject: [PATCH 0273/1958] mac80211: QoS multicast frames have No Ack policy

Previously QoS multicast frames had the Normal Acknowledgment QoS
control bits set. This would cause broadcast frames to be discarded by
peers with which we have a BA session, since their sequence number would
fall outside the allowed range. Set No Ack QoS control bits on multicast
QoS frames and filter these in de-aggregation code.

Subject: [PATCH 0274/1958] mac80211: check if frame is really part of this BA

There was an an implicit assumption that any QoS data frame received
from a STA/TID with an active BA session was sent to this vif as part of
a BA.  This is not true if IFF_PROMISC is enabled and the frame was
destined for a different peer, for example. Don't treat these frames as
part of a BA from the sending STA.

Subject: [PATCH 0275/1958] mac80211: simplify mesh frame queue mapping and QoS

We only need to set the skb queue twice:

1. by the netdev, on local TX.
2. when forwarding a mesh frame.

We only need to set the qos header twice:

1. by mac80211, on local TX.
2. when putting a frame on the mpath->frame_queue

We also don't need the RA in order to set the proper queue mapping since
all mesh STAs are QoS, indicate this and do it once when the frame is
received. Also fixes an issue where the QoS header and queue mapping was not
set for unicast forwarded frames.

Subject: [PATCH 0276/1958] mac80211: add helper to free TX skb

Drivers that need to drop a frame before it
can be transmitted will usually simply free
that frame. This is currently fine, but in
the future it'll be needed to tell mac80211
about this case, so add a new routine that
frees a TX skb.

Subject: [PATCH 0278/1958] nl80211: allow subscribing to unexpected class3
 frames

To implement AP mode without monitor interfaces we
need to be able to send a deauth to stations that
send frames without being associated. Enable this
by adding a new nl80211 event for such frames that
an application can subscribe to.

Add the ability to advertise that the device
contains the AP SME and what features it can
support. There are currently no features in
the bitmap -- probe response offload will be
advertised by a few patches Arik is working
on now (who took over from Guy Eilam) and a
device with AP SME will typically implement
and require response offload.

Subject: [PATCH 0281/1958] nl80211: add API to probe a client

When the AP SME in hostapd is used it wants to
probe the clients when they have been idle for
some time. Add explicit API to support this.

Subject: [PATCH 0283/1958] cfg80211: allow registering to beacons

Add the ability to register to received beacon frames
to allow implementing OLBC logic in userspace. The
registration is per wiphy since there's no point in
receiving the same frame multiple times.

If there's an interface in AP mode, OBSS beacons
are needed by hostapd/wpa_s to implement logic to
enable/disable protection etc. Report the frames
and set the capability flag.

Subject: [PATCH 0287/1958] cfg80211/mac80211: allow management TX to not wait
 for ACK

For probe responses it can be useful to not wait for ACK to
avoid retransmissions if the station that sent the probe is
already on the next channel, so allow userspace to request
not caring about the ACK with a new nl80211 flag.

Since mac80211 needs to be updated for the new function
prototype anyway implement it right away -- it's just a
few lines of code.

Subject: [PATCH 0289/1958] brcm80211: fmac: move chip recognition function to
 sdio_chip.c

Currently backplane handle code is scatterd around dhd_sdio.c which
is not good for maintenance and adding new backplane interconnect
type support. This patch and the follow up patches are going to
abstract all chip backplane control code specific for sdio bus
into this new sdio_chip.c

We dereference adapter in the error handling code so this needed to

so adapter can never be NULL and I've removed the NULL check.

OK I found it, I did some extra tests and believe its ready.

[PATCH net-next] ipv4: IP_PKTINFO doesnt need dst reference

When a socket uses IP_PKTINFO notifications, we currently force a dst
reference for each received skb. Reader has to access dst to get needed
information (rt_iif & rt_spec_dst) and must release dst reference.

We also forced a dst reference if skb was put in socket backlog, even
without IP_PKTINFO handling. This happens under stress/load.

We can instead store the needed information in skb->cb[], so that only
softirq handler really access dst, improving cache hit ratios.

This removes two atomic operations per packet, and false sharing as
well.

On a benchmark using a mono threaded receiver (doing only recvmsg()
calls), I can reach 720.000 pps instead of 570.000 pps.

IP_PKTINFO is typically used by DNS servers, and any multihomed aware
UDP application.

Since the command can fail we need to have a proper response with the
remote address and a failure status for it. This also updates it to
conform to the latest mgmt API spec.

Subject: [PATCH 0319/1958] Bluetooth: Allow L2CAP to increase the security
 level

Some incomming connections needs to increase the security level by
requesting encryption for example (HID keyboard case). This change allows
the userspace to change it through setsockopt with defer_setup enabled.

It is not necessary to use spinlock primitive to
protect data which is accessed in hard irq context as
nothing is running in hard irq with this driver. The
spinlock primitive meant to protect data in softirq
context is more appropriate.

Subject: [PATCH 0324/1958] ath6kl: Claim sdio function only at appropriate
 places

There are places where tx_complete callbacks are called with
claiming the sdio function. It is not necessary to hold the
sdio func for longer. This may even affect the host side power
save, if it is supported by the controller.

Subject: [PATCH 0325/1958] ath6kl: Fix htc_packet leak in
 ath6kl_htc_rx_process_packets()

Packet is not reclaimed when ath6kl_htc_rx_process_hdr() fails.
Fix this by deferring the packet deletion from comp_pktq till
ath6kl_htc_rx_process_hdr() returns success. This bug is found
in code review, impact is not easily visible as the leak happens
only in failure cases.

smatch found that skb might be null in some cases in ath6kl_rx():

ath6kl/txrx.c +1252 ath6kl_rx(222) error: potential null derefence 'skb'.

This will happen when ath6kl is in AP mode and two clients send traffic
to each other.

Subject: [PATCH 0340/1958] ath6kl: Add debugfs files for roaming control

Roaming mode can be changed by writing roam mode (default, bssbias, or
lock) to roam_mode. Forced roam can be requested by writing the BSSID
into force_roam.

Subject: [PATCH 0341/1958] ath6kl: Add debugfs control for keepalive and
 disconnection timeout

The new debugfs files keepalive and disconnect_timeout can be used to
fetch the current values and to change the values for keepalive and
disconnect event timeout (both in seconds).

Sangwook found out that commit 639d0b89 ("ath6kl: read firmware start
address from hardware") broke firmware boot on ar6003 hw2.0 as it seems
it's not posible to automatically query the address from hardware. So
we need to hardcode the address for hw2.0.

Subject: [PATCH 0345/1958] ath6kl: Fix endpoint_stats debugfs buffer length
 calculation

The previous version did not really make much sense and the theoretical
maximum length would be a bit longer. Calculate the length more
accurately. In addition, there is no need to clear the buffer, so use
kmalloc instead of kzalloc. For bonus points, add the forgotten
cred_rpt_from_other value to the file.

Subject: [PATCH 0346/1958] ath6kl: Implement support for QOS-enable and
 QOS-disable from userspace

In order to allow user space based QOS control we use the available debugfs
infrastructure. With this feature, user can make changes to qos parameters,
thereby allowing creation and deletion of user defined priority streams and
features like uapsd. This feature has been added for testing purposes.

All 21 parameters for the create_qos command are mandatory in the correct
order. They have to be written to the create_qos file in
the ath6kl debug directory. These parameters(in order) are:

1)user priority
2)direction
3)traffic class
4)traffic type
5)voice PS capability

To create a qos stream:

echo "6 2 3 1 1 9999999 9999999 9999999 7777777 0 6 45000 200 56789000
56789000 5678900 0 0 9999999 20000 0" > create_qos

delete_qos requires 2 parameters:

1)traffic class
2)tsid

To delete a qos stream:

echo "3 1" > delete_qos

kvalo: minor commit log cleanup

Subject: [PATCH 0347/1958] ath6kl: merge htc debug levels

It's not really necessary to have separate debug levels for htc tx and rx
so combine them.

Subject: [PATCH 0349/1958] ath6kl: don't dump full htc packets

It's currently possible to dump full sdio packets, so dumping htc packets
is not strictly needed. So remove it, we can always add it back if
there ever comes a need for that.

Subject: [PATCH 0351/1958] ath6kl: Implement support for background scan
 control from userspace

In order to allow user space based control of background scan interval,
we use available debugfs infrastructure. The feature has been added for
testing purposes. The user has to write the bgscan interval (in secs) to
the bgscan_interval file in ath6kl debug directory. To disable bgscan,
a '0' is to be written to the bgscan_interval file.

Example:

echo "2" > bgscan_interval

This will make the background scan interval as 2 seconds

kvalo: changed implementation so that there's only one call to
ath6kl_wmi_scanparams_cmd()

Subject: [PATCH 0355/1958] ath6kl: Cleanup fw interface type setting

It is not necessary to use ath6kl_get_fw_iftype() to find out the
firmware interface type during initialization because the type
of the initial interface in INFRA_NETWORK. Hardcode the fw interface
type corresponding to INFRA_BSS instead of using ath6kl_get_fw_iftype().

Subject: [PATCH 0371/1958] ath6kl: Cleanup parameters in
 ath6kl_init_control_info() and ath6kl_init_profile_info()

Pass vif structure to those functions instead of ath6kl because these
functions do vif specific information initialization.

Subject: [PATCH 0377/1958] ath6kl: Use the other variant of netdev
 (un)register APIs

Use replace (un)register_netdev() with (un)register_netdevice()
so that the same ath6kl function can be used with
add_virtual_intf()/del_virtual_intf().

Subject: [PATCH 0380/1958] ath6kl: Add a modparam to enable multi normal
 interface support

This option lets operate more than one vif in normal mode (AP/STA/IBSS)
when support for multiple vif is enabled. This modparam needs to be used
as

modprobe ath6kl multi_norm_if_support=1

From: Kalle Valo <kvalo@qca.qualcomm.com>
Date: Mon, 24 Oct 2011 12:17:20 +0300
Subject: [PATCH 0387/1958] ath6kl: move all credit distribution code to htc.c

As htc is the only user there's no reason to keep it in main.c.

No functional changes.

Subject: [PATCH 0393/1958] ath6kl: Implement support for listen interval from
 userspace

In order to allow user space based control of listen interval, we use
available debugfs infrastructure. Listen interval implies how frequently
we want the WLAN chip to wake up and synchronize the beacons in case it
is in sleep mode. The command requires two parameters in the following order:

1) listen_interval_time
2) listen_interval_beacons

The user has to write the listen interval_time (in msecs) and
listen_interval_beacons (in no. of beacons) to the listen_interval file in
ath6kl debug directory.

Example:

echo "30 1" > listen_interval

 control from userspace

In order to allow user space based control of power parameters, we use
available debugfs infrastructure. With these features user can control
power consumption by adjusting various sleep/wake up related parameters.
The feature has been added for testing purposes. All 5 parameters are
mandatory in correct order. They have to be written to the power_params
file. These are:

1) idle_period
2) no_of_pspoll
3) dtim_policy
4) tx_wakeup_policy
5) no_tx_to_wakeup

Example:

echo "200 1 0 1 1" > power_params

Subject: [PATCH 0396/1958] ath6kl: Report unique remain-on-channel cookie
 values

Even though only a single concurrent remain-on-channel operation is
supported, there may be two pending remain-on-channel events (one to
indicate end of a canceled operation and another to indicate start of a
new operation). User space won't be able to distinguish these events
unless unique cookies are used.

The previous behavior resulted in wpa_supplicant getting quite
confused about the driver's offchannel state in various sequences
and this made the P2P state machine behave incorrectly. Use of
more than a single remain-on-channel cookie value fixes this.

Use of cfg80211_scan_request is not valid after calling cfg80211_scan_done()
but ath6kl_cfg80211_scan_complete_event() was doing exactly that. Change
the function to call cfg80211_scan_done() last.

This was found during code review, I didn't see any visible problems
due to this bug.

Subject: [PATCH 0403/1958] ath6kl: separate hardware boot code from module
 initialisation code

Refactor the code needed to boot the hardware to a separate function so
that it will be easier boot and shutdown hardware.

No functional changes (hopefully).

Subject: [PATCH 0407/1958] ath6kl: don't print an error for canceled packets

ath6kl_tx_complete() was printing an error when packet was canceled.
That causes unnecessary errors when hardware is powered off.

Also change the error to a warning and cleanup the message.

Currently the name of the driver in struct sdio_driver is "ath6kl_sdio",
this is for example what uevent advertises. This is wrong as the module
is named as ath6kl.ko. Change it to "ath6kl" so that the names match.

Subject: [PATCH 0410/1958] ath6kl: power down hardware when interface is down

The benefit from this is that user space can control hardware's power state
by putting interface up and down. This is handy if firmware gets to some
weird state.

The downside will be that putting interface up takes a bit longer,
I was measuring ~500 ms during interface up.

Subject: [PATCH 0411/1958] ath6kl: fix WLAN_ENABLE usage in ath6kl_close()

If ath6kl_init_hw_stop() failed with an error WLAN_ENABLED would not
be cleared. Found during code review and just a theoretical issue.

Currently firmware crash dump is printed only if debug is enabled.
Change it so that the crash dump is always printed.

Also move the code from init.c to hif.c.

Subject: [PATCH 0414/1958] ath6kl: add aborted parameter to
 ath6kl_cfg80211_scan_complete_event()

Currently it takes an error code as status, but what we really want to
tell is if the scan was aborted or not.

Also fix a bug where we were comparing firmware scan status values
with kernel error codes, which is obviously wrong. This meant
that ath6kl didn't detect when firmware informed about failed scans. I
doubt that this fix doesn't make any difference in practise but it
still needs to be fixed. This is fixed by adding an enum for the success
status code and checking for that.

Subject: [PATCH 0417/1958] ath6kl: implement ath6kl_cfg80211_suspend()

This is in preparation for cutpower suspend feature. HIF layer makes
the decision based on information provided by cfg80211 and what hardware
actually supports. Then it calls ath6kl_cfg80211_suspend() to enable
the chosen mode.

Functionality should be the same, this is just preparation for
more suspend modes (cutpower and wow).

Subject: [PATCH 0418/1958] ath6kl: add state variable depicting hw/fw state

This way it's easier to track state changes and in the future add
more warnings about using hardware in wrong states. Currently there
are few random flags for trying to do the same, those will be cleaned
and removed in the future.

Subject: [PATCH 0420/1958] ath6kl: cut power during suspend

If sdio controller doesn't support keep power, cut power from hardware
during suspend and restart firmware during resume. If we are connected
during suspend, send a disconnected event to user space.

Earlier suspend failed with an error if sdio didn't support keep power.
Now suspend will happen succesfully even with that case.

Subject: [PATCH 0421/1958] ath6kl: Fix lockdep warning

The following is the lockdep warning which detects possible
deadlock condition with the way ar->lock and ar->list_lock
are being used.

  (&(&ar->lock)->rlock){+.-...}, at: [<ffffffffa0492d13>] ath6kl_indicate_tx_activity+0x83/0x110 [ath6kl]
 but this lock took another, SOFTIRQ-unsafe lock in the past:
  (&(&ar->list_lock)->rlock){+.+...}

 and interrupts could create inverse lock ordering between them.

 other info that might help us debug this:
  Possible interrupt unsafe locking scenario:

        CPU0                    CPU1
        ----                    ----
   lock(&(&ar->list_lock)->rlock);
                                local_irq_disable();
                                lock(&(&ar->lock)->rlock);
                                lock(&(&ar->list_lock)->rlock);
   <Interrupt>
     lock(&(&ar->lock)->rlock);

  *** DEADLOCK ***

softirqs have to be disabled when acquiring ar->list_lock to avoid
the above deadlock condition. When the above warning printed the
interface is still up and running without issue.

Subject: [PATCH 0422/1958] ath6kl: don't power down hardware when interface is
 down

Jouni reported that my patch "ath6kl: power down hardware when interface
is down" caused a regression on his x86 boxes and scan didn't work anymore.
I was able to reproduce the problem by disabling all debug messages.

So there has to be a race condition somewhere in the code and disable the
functionality until the race is fixed. Now hardware is powered from the
point where module is loaded until it's removed.

Subject: [PATCH 0423/1958] ath6kl: add suspend_cutpower module parameter

This is to force ath6kl to power off hardware during suspend even if
sdio support keep power. This is needed, for example, when sdio
controller is buggy or maximum powersaving is desired.

Usage:

insmod ath6kl.ko suspend_cutpower=1

Subject: [PATCH 0430/1958] ath6kl: Include new parameter in suspend path for
 wowlan

cfg80211 layer provides user defined wow parameters like Filter options, Patterns,
Pattern's mask, etc via "struct cfg80211_wowlan *wow" to suspend function.

Right now, this wowlan parameter is not handled in __ath6kl_cfg80211_suspend func.
This parameter has to be passed to HIF layer, So that it can be passed back to
ath6kl's cfg interface layer when WOW mode is selected.

In case of deep sleep and cut power mode, it's not handled.

Subject: [PATCH 0433/1958] ath6kl: Invoke WOW suspend/resume calls during PM
 operation

Link ath6kl's wow suspend/resume functions with the actual suspend/resume path.

WOW mode is selected when the host sdio controller supports both
MMC_PM_KEEP_POWER and MMC_PM_WAKE_SDIO_IRQ capabilities.

kvalo: also adds a missing break in ath6kl_cfg80211_resume(), luckily
it didn't have any effect on functionality.

Subject: [PATCH 0434/1958] ath6kl: Perform WOW resume in RX path in case of
 SDIO IRQ wake up

The target triggers sdio data line to wake up the host when
WOW pattern matches. This causes sdio irq handler is being
executed in the host side which internally hits ath6kl's RX path.

WOW resume should happen before start processing any data from
the target. So it's required to perform WOW resume in RX path.

This area needs bit rework to avoid WOW resume in RX path,
As of now it's fine to have this model, rework will be done later.

Subject: [PATCH 0435/1958] ath6kl: Remove WARN_ON msg in Suspend path

In the current code, WOW resume is executed first from RX path
and ar->state is moved to ATH6KL_STATE_ON. When platform calls
ath6kl_sdio_resume() in CFG resume context, that time ar->state
could have moved to ON state. Printing WARN_ON(1) is void in
this context. Hence removing this.

Once WOW resume is removed from RX path, This WARN_ON msg can be
reverted.

Subject: [PATCH 0438/1958] ath6kl: Fix tx packet drop in AP mode with bridge

skb is dropped in ath6kl_data_tx() when the headroom in skb
is insufficient. We hit this condition for every skb in AP mode
which is used with bridge, so all tx packets are getting dropped
when tried to send traffic to wireless client from bridge. Fix
this by reallocating the headroom instead of dropping the skb
when it has lesser headroom than needed.

Subject: [PATCH 0439/1958] ath6kl: Fix error in writing create_qos debugfs

100 bytes are allocated to store the parameters which are needed
to create a priority stream. These 100 bytes are not sufficiant and
throws error when running the following command.

echo "6 2 3 1 1 9999999 9999999 9999999 7777777 0 6 45000 200 56789000
 56789000 5678900 0 0 9999999 20000 0" > create_qos

179 bytes are needed when the following vlaues are given so that
a maximum possible value in that data type can be given in decimal.

echo "255 255 255 255 255 4294967295 4294967295 4294967295 4294967295
 4294967295 255 65535 65535 4294967295 4294967295 4294967295 4294967295
 4294967295 4294967295 4294967295 4294967295" > create_qos

Following takes 187 bytes when given in hex

echo "0xff 0xff 0xff 0xff 0xff 0xffffffff 0xffffffff 0xffffffff 0xffffffff 0xffffffff
 0xff 0xffff 0xffff 0xffffffff 0xffffffff 0xffffffff 0xffffffff 0xffffffff 0xffffffff
 0xffffffff 0xffffffff" > create_qos

Increase the size to 200 bytes so that it can hold upto the maximum
value possible for that data type.

Subject: [PATCH 0440/1958] cfg80211: merge in beacon ies of hidden bss.

The problem with PSM when a hidden SSID was used was originally
reported by Juuso Oikarinen.

 - When generally scanning, the AP is getting a bss entry with
   a zero SSID.
 - When associating, a probe-req is sent to the AP with the SSID,
   and as a result a probe-response is received with the hidden
   SSID in place. As a consequence, a second bss entry is created
   for the AP, now with the real SSID.
 - After association, mac80211 executes ieee80211_recalc_ps(),
   but does not switch to powersave because the beacon-ies are missing.

As result, the STA does not ever enter PSM.

The patch merges in beacon ies of hidden bss from beacon to the probe
response, creating a consistent set of ies in place.

Patch is depended on "cfg80211: fix cmp_ies" made by Johannes.

Initialize rate control algorithms only when supported rates are known
for a TDLS peer sta. Direct Tx between peers is not allowed before the
link is enabled. In turn, this only occurs after a change_station()
call that sets supported rates.

Subject: [PATCH 0447/1958] mwifiex: remove unnecessary free_priv handler

Cfg80211 stack allocates private area for driver use in
struct cfg80211_bss. It will be freed by stack in bss_release().
Driver don't need to worry about it.

In mwifiex driver, we use the private area just to store band
information(u8). We don't allocate memory explicitly and store
it's pointer in bss->priv. Hence we don't have any cleanup work
to do in free_priv handler. Currently we try to free the allocated
private area in free_priv handler which is not correct.

This patch removes unnecessary free_priv handler.

Subject: [PATCH 0453/1958] mac80211: simplify scan state machine

Attempting to micro-optimise the scan by going
fully live again when scanning the operating
channel just made the code extremely complex
and has little gain in most use cases. Remove
all that code and simplify the state machine
again.

Subject: [PATCH 0462/1958] nl80211: fix compiler warning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

John reported the following warning:

net/wireless/nl80211.c: In function ‘nl80211_tx_mgmt’:
net/wireless/nl80211.c:5286:8: warning: ‘hdr’ may be used uninitialized in this function

Evidently, his version of gcc isn't able to see that
when "msg" is initialized, "hdr" must also be. My
gcc, 4.6.1, can actually see that and doesn't warn.
Simply initialize the variable to NULL. That means
if the compiler was ever right we'll crash though so
isn't really optimal since it may hide warnings from
the compiler when somebody modifies this code in the
future.

Subject: [PATCH 0463/1958] nl80211: Add probe response offload attribute

Notify user-space about probe-response offloading support in the driver.

A wiphy flag is used to indicate support and a bitmap of protocols
determines which protocols are supported.

Subject: [PATCH 0465/1958] mac80211: Save probe response data for bss

Allow setting a probe response template for an interface operating in
AP mode. Low level drivers are notified about changes in the probe
response template and are able to retrieve a copy of the current probe
response. This data can, for example, be uploaded to hardware as a
template.

Retriving tx power for 2x2 and 3x3 chainmask is not handled
properly. While calculating tx power for 2x2, 3 dBm was reduced
and for 3x3, 5 dBm was reduced which should be added back when
retriving.

Subject: [PATCH 0468/1958] iwlagn: add P2P NoA to probe responses

Whether to use NoA or not is entire controlled
by the uCode right now, and it also adds the
attribute to beacons. We do need to add it to
probe responses in the driver though.

Keep track of the NoA notification from the
uCode and add the data to probe responses when
such are transmitted. Use RCU to manage the
lifetime.

Subject: [PATCH 0469/1958] iwlwifi: Suppress noisy syslog messages when
 RF_KILL switch engaged

When a station is associated with an AP and the RF_KILL switch is engaged,
numerous error messages were sent to the system log. The error messages
were the result of the failure(s) of the various submodules to perform
their tasks after the radios were disabled.

To resolve this situation, the messages were modified to use a new macro,
IWL_DEBUG_QUIET_RFKILL. This macro allows for the RF_KILL error messages
to be sent to the log provided that IWL_DEBUG is true and IWL_DL_RADIO
is '1'. For all other cases, the error messages resulting from an RFKILL
event will not be sent to the system log. Messages logged because of an
RFKILL will be tagged with the prefix '(RFKILL)' to clarify the cause of
the error.

Subject: [PATCH 0472/1958] iwlagn: fix NULL ptr deref when reprogramming sta
 w/o LQ

Reinette reports a crash in iwl_reprogram_ap_sta(). The
debugging shows:

  b1 16    mov    $0x16,%cl
 *f3 a5    rep movsl %ds     <-- trapping instruction:(%rsi),%es:(%rdi)

which is a memcpy of 22 (0x16) words (movsl). this points
to "priv->stations[sta_id].lq" being NULL since that is
the memcpy() of that size here.

The only way I see for this to happen is if we try to
do some RXON reprogramming while connecting to an AP,
after tx_sync() but before full setup, but that seems
like something that might very well happen.

Fix this by checking if the LQ is present and only then
reprogramming it.

Subject: [PATCH 0475/1958] iwlagn: remove knowledge of ucode image location
 from upper layers

The upper layers of the driver do not need to know where the ucode is
stored.  It already passes in an enum of which ucode to load.  Let the
lower layer routines select the ucode to load.

From 7335613ae27ae148fde720caccbfbbd9afa7465d Mon Sep 17 00:00:00 2001
From: Wey-Yi Guy <wey-yi.w.guy@intel.com>
Date: Thu, 10 Nov 2011 06:55:11 -0800
Subject: [PATCH 0478/1958] iwlwifi: move all mac80211 related functions to one
 place

There are many mac80211 callback functions in the driver, as current
implementation, those functions are scatter everywhere which is very difficult
to find and maintain, move all the mac80211 callback functions into single
file. There should be no functional changes

Subject: [PATCH 0479/1958] iwlagn: use per-vif AC parameters

Eliad added the ability to configure AC parameters
per virtual interface; make use of this in iwlwifi
and set the parameters in the right context. Since
storage and uploading to the device is already per
context, this is sufficient.

Subject: [PATCH 0480/1958] iwlagn: explicitly program P2P QoS parameters

In P2P device mode, the device needs to have valid
QoS parameters. We currently have those because we
program parameters from any virtual interface into
all contexts, but not only do we want to get rid of
this -- it is also unpredictable since on the BSS
context we might have any parameters, and there it
might even be programmed for HT.

Explicitly program default QoS parameters into the
PAN context for P2P (the defaults are 11g but with
QoS disabled) to make device behaviour predictable.

This also helps when in a follow-up patch we will
use TX QoS parameters from mac80211 only for the
context they were meant for -- without this first
that would completely break P2P device discovery.

Subject: [PATCH 0484/1958] iwlwifi: Move the core suspend function to
 iwl-agn-lib

The core suspend function is part of agn, iwl_mac80211 should only
handle mac80211 I/F operations.

Subject: [PATCH 0489/1958] iwlagn: don't always split remain-on-channel

Due to the P2P context always having the associated
bit set when we got to this code, we were splitting
up the remain-on-channel durations unconditionally.
This isn't needed -- if the P2P context is in P2P
device type mode it doesn't impose restrictions on
timing to skip it in that case.

Subject: [PATCH 0492/1958] iwlwifi: fix rate-scaling algorithm for BT combo
 devices

iwlwifi tries to avoid using antenna B in BT combo devices when BT
is active. A bug in the rate-scaling algorithm was causing the combo
device to never attempt MIMO rates. Fix the algorithm to
opportunistically try MIMO rates when BT traffic is low.

There were a couple of code segments left that were placed under
a macro definition that was not applicable or not used in the
brcmsmac driver. These pieces of code have been removed.

Subject: [PATCH 0497/1958] brcm80211: smac: replace own access category
 definitions with mac80211 enum

The brcmsmac had own definitions for the access categories. The mac80211
header provides these as well as they are used in the conf_tx callback.
As the definitions did not match the driver configured the tx parameters
to the wrong queue.

Subject: [PATCH 0505/1958] brcm80211: smac: remove usage of brcmu_pkttotlen

The function brcmu_pkttotlen calculates the total length of a sk_buff
chain following the next pointer. In brcmsmac this is not needed as
in each place where it was used the provided sk_buff had a NULL pointer
as next field value.

The functions brcmu_pkttotlen() is only used in brcmfmac driver
so it has been moved there. It also does not use the sk_buff
next pointer anymore but walks a skb queue to determine the total
length.

Subject: [PATCH 0509/1958] brcm80211: util: remove pointer traversal from
 brcmu_pkt_buf_free_skb

The function brcmu_pkt_buf_free_skb() was following the next pointer
to free all linked packets. However, it is only called with unlinked
packets so this can be removed.

Subject: [PATCH 0518/1958] be2net: don't log more than one error on detecting
 EEH/UE errors

Currently we're spamming error messages each time a FW cmd call is made
while in EEH/UE error state. One log msg on error detection is enough.

Subject: [PATCH 0519/1958] be2net: stop issuing FW cmds if any cmd times out

A FW cmd timeout (with a sufficiently large timeout value in the
order of tens of seconds) indicates an unresponsive FW. In this state
issuing further cmds and waiting for a completion will only stall the process.

Subject: [PATCH 0523/1958] ath6kl: Fix accessing wrong skb->data in
 ath6kl_tx_complete()

When buffer alignmnet is applied, the data pointer of skb taken from
cookie will no longer point to the first byte of the actual data.
But the skb->data pointer is used in ath6kl_tx_complete() to get
the index of the virtual interface which will not give the correct
interface index and sometimes may give the following WARN_ON() message.
Use packet->buf instead of skb->data to fix this.

Subject: [PATCH 0524/1958] ath6kl: Fix packet drop when ath6kl_cookie runs out

"ath6kl: Maintain virtual interface in a list" mistakenly stops the
netq only when the mode is ibss. This causes packet drops in sta mode
when the available cookies (buffer abstraction in ath6kl and also used
for tx throttling) runs out for the highest priority traffic. This patch
just fixes this regression though the original code may still need fixes
which can be addressed in separate patches.

In addition to this, one debug message is also added to know

Subject: [PATCH 0526/1958] ath6kl: Fix target minimum length requirement for
 WMI_SEND_PROBE_RESPONSE_CMDID

The firmware expects the minimum length of
WMI_SEND_PROBE_RESPONSE_CMDID to be 13. However, when the device is a
P2P GO and it needs to send a probe response to a non-P2P client,
there are no P2P IEs to be added, and therefore the length of the WMI
command is 12. This command gets rejected by the firmware. To fix
this, add an extra byte to satisfy the minimum length requirement.

Subject: [PATCH 0533/1958] ath6kl: add hif_type

In some rare cases core code needs to know what hif type is used. Add
a field to struct ath6kl to denote that. Hopefully this is just a
temporary solution.

Subject: [PATCH 0534/1958] ath6kl: add USB support

Add USB support for ar6004. Currently only firmware can be booted,
no commands can be sent to firmware yet as HTC layer doesn't work
with USB yet.

Based on patches by Kevin Fang.

As HTC layer doesn't support USB devices return an error if that happens.
USB support will be added to HTC in the future, this is just a temporary
solution.

Now two modules are built, ath6kl_sdio.ko and ath6kl_usb.ko. But the USB
module isn't fully functional yet as HTC layer is missing support and
that's why it's marked as experimental for now.

Subject: [PATCH 0537/1958] ath6kl: Fix bug in setting default key index for tx
 in AP mode

vif->def_txkey_index is set to key_index in ath6kl_cfg80211_add_key().
If the interface is configured with multiple static wep keys,
vif->def_txkey_index would be holding the index of the last key configured,
not the default tx key index. Remove this unnecessary default key index setting
in ath6kl_cfg80211_add_key() to configure the right key index in WEP thereby
make it work when multiple wep keys are configured.

A patch in wpa_supplicant (wpa_supplicant: Set configured auth_algs)

Subject: [PATCH 0543/1958] bnx2x: propagate DCBX negotiation

We need propagate the DCBX results from PMF to other functions
on the same port, in order to properly update netdev structure
and allow following new ETS and PFC configurations.

The race may cause access of registers while MAC hw block is
in reset state. As a result syslog will show error messages.
We can prevent this by using state from local variable.

Subject: [PATCH 0551/1958] net: introduce ethernet teaming device

This patch introduces new network device called team. It supposes to be
very fast, simple, userspace-driven alternative to existing bonding
driver.

Userspace library called libteam with couple of demo apps is available
here:
https://github.com/jpirko/libteam
Note it's still in its dipers atm.

team<->libteam use generic netlink for communication. That and rtnl
suppose to be the only way to configure team device, no sysfs etc.

Python binding of libteam was recently introduced.
Daemon providing arpmon/miimon active-backup functionality will be
introduced shortly. All what's necessary is already implemented in
kernel team driver.

v7->v8:
	- check ndo_ndo_vlan_rx_[add/kill]_vid functions before calling
	  them.
	- use dev_kfree_skb_any() instead of dev_kfree_skb()

v6->v7:
	- transmit and receive functions are not checked in hot paths.
	  That also resolves memory leak on transmit when no port is
	  present

v5->v6:
	- changed couple of _rcu calls to non _rcu ones in non-readers

v4->v5:
	- team_change_mtu() uses team->lock while travesing though port
	  list
	- mac address changes are moved completely to jurisdiction of
	  userspace daemon. This way the daemon can do FOM1, FOM2 and
	  possibly other weird things with mac addresses.
	  Only round-robin mode sets up all ports to bond's address then
	  enslaved.
	- Extended Kconfig text

v3->v4:
	- remove redundant synchronize_rcu from __team_change_mode()
	- revert "set and clear of mode_ops happens per pointer, not per
	  byte"
	- extend comment of function __team_change_mode()

v2->v3:
	- team_change_mtu() uses rcu version of list traversal to unwind
	- set and clear of mode_ops happens per pointer, not per byte
	- port hashlist changed to be embedded into team structure
	- error branch in team_port_enter() does cleanup now
	- fixed rtln->rtnl

v1->v2:
	- modes are made as modules. Makes team more modular and
	  extendable.
	- several commenters' nitpicks found on v1 were fixed
	- several other bugs were fixed.
	- note I ignored Eric's comment about roundrobin port selector
	  as Eric's way may be easily implemented as another mode (mode
	  "random") in future.

Subject: [PATCH 0552/1958] ipv6: reduce percpu needs for icmpv6msg mibs

Reading /proc/net/snmp6 on a machine with a lot of cpus is very
expensive (can be ~88000 us).

This is because ICMPV6MSG MIB uses 4096 bytes per cpu, and folding
values for all possible cpus can read 16 Mbytes of memory (32MBytes on
non x86 arches)

ICMP messages are not considered as fast path on a typical server, and
eventually few cpus handle them anyway. We can afford an atomic
operation instead of using percpu data.

This saves 4096 bytes per cpu and per network namespace.

+6LoWPAN Linux implementation
+============================
+
+The IEEE 802.15.4 standard specifies an MTU of 128 bytes, yielding about 80
+octets of actual MAC payload once security is turned on, on a wireless link
+with a link throughput of 250 kbps or less.  The 6LoWPAN adaptation format
+[RFC4944] was specified to carry IPv6 datagrams over such constrained links,
+taking into account limited bandwidth, memory, or energy resources that are
+expected in applications such as wireless Sensor Networks.  [RFC4944] defines
+a Mesh Addressing header to support sub-IP forwarding, a Fragmentation header
+to support the IPv6 minimum MTU requirement [RFC2460], and stateless header
+compression for IPv6 datagrams (LOWPAN_HC1 and LOWPAN_HC2) to reduce the
+relatively large IPv6 and UDP headers down to (in the best case) several bytes.
+
+In Semptember 2011 the standard update was published - [RFC6282].
+It deprecates HC1 and HC2 compression and defines IPHC encoding format which is
+used in this Linux implementation.
+
+All the code related to 6lowpan you may find in files: net/ieee802154/6lowpan.*
+
+To setup 6lowpan interface you need (busybox release > 1.17.0):
+1. Add IEEE802.15.4 interface and initialize PANid;
+2. Add 6lowpan interface by command like:
+   # ip link add link wpan0 name lowpan0 type lowpan
+3. Set MAC (if needs):
+   # ip link set lowpan0 address de:ad:be:ef:ca:fe:ba:be
+4. Bring up 'lowpan0' interface

Subject: [PATCH 0560/1958] fsl_pq_mdio: Clean up tbi address configuration

The code for setting the address of the internal TBI PHY was
convoluted enough without a maze of ifdefs. Clean it up a bit
so we allow the logic to fail down to -ENODEV at the end of
the if/else ladder, rather than using ifdefs to repeat the same
failure code over and over.

Also, remove the support for the auto-configuration. I'm not aware of
anyone using it, and it ends up using the bus mutex before it's been
initialized.

More changes to the recent code to support control of forwarding
database via netlink.
   * Support NTF_USE like neighbour table
   * Validate state bits from application
   * Only send notifications (and change bits) if new entry is
     different.

Ouch, this was fixed on one machine yesterday, but not the other one I
used this morning, sorry.

[PATCH V5 net-next] neigh: new unresolved queue limits

unres_qlen is the number of frames we are able to queue per unresolved
neighbour. Its default value (3) was never changed and is responsible
for strange drops, especially if IP fragments are used, or multiple
sessions start in parallel. Even a single tcp flow can hit this limit.

$ arp -d 192.168.20.108 ; ping -c 2 -s 8000 192.168.20.108
PING 192.168.20.108 (192.168.20.108) 8000(8028) bytes of data.
8008 bytes from 192.168.20.108: icmp_seq=2 ttl=64 time=0.322 ms

Subject: [PATCH 0566/1958] net: introduce build_skb()

One of the thing we discussed during netdev 2011 conference was the idea
to change some network drivers to allocate/populate their skb at RX
completion time, right before feeding the skb to network stack.

In old days, we allocated skbs when populating the RX ring.

This means bringing into cpu cache sk_buff and skb_shared_info cache
lines (since we clear/initialize them), then 'queue' skb->data to NIC.

By the time NIC fills a frame in skb->data buffer and host can process
it, cpu probably threw away the cache lines from its caches, because lot
of things happened between the allocation and final use.

So the deal would be to allocate only the data buffer for the NIC to
populate its RX ring buffer. And use build_skb() at RX completion to
attach a data buffer (now filled with an ethernet frame) to a new skb,
initialize the skb_shared_info portion, and give the hot skb to network
stack.

build_skb() is the function to allocate an skb, caller providing the
data buffer that should be attached to it. Drivers are expected to call
skb_reserve() right after build_skb() to adjust skb->data to the
Ethernet frame (usually skipping NET_SKB_PAD and NET_IP_ALIGN, but some
drivers might add a hardware provided alignment)

Data provided to build_skb() MUST have been allocated by a prior
kmalloc() call, with enough room to add SKB_DATA_ALIGN(sizeof(struct
skb_shared_info)) bytes at the end of the data without corrupting
incoming frame.

data = kmalloc(NET_SKB_PAD + NET_IP_ALIGN + 1536 +
               SKB_DATA_ALIGN(sizeof(struct skb_shared_info)),
	       GFP_ATOMIC);
...
skb = build_skb(data);
if (!skb) {
	recycle_data(data);
} else {
	skb_reserve(skb, NET_SKB_PAD + NET_IP_ALIGN);
	...
}

Subject: [PATCH 0567/1958] bnx2x: uses build_skb() in receive path

bnx2x uses following formula to compute its rx_buf_sz :

dev->mtu + 2*L1_CACHE_BYTES + 14 + 8 + 8 + 2

Then core network adds NET_SKB_PAD and SKB_DATA_ALIGN(sizeof(struct
skb_shared_info))

Final allocated size for skb head on x86_64 (L1_CACHE_BYTES = 64,
MTU=1500) : 2112 bytes : SLUB/SLAB round this to 4096 bytes.

Since skb truesize is then bigger than SK_MEM_QUANTUM, we have lot of
false sharing because of mem_reclaim in UDP stack.

One possible way to half truesize is to reduce the need by 64 bytes
(2112 -> 2048 bytes)

Instead of allocating a full cache line at the end of packet for
alignment, we can use the fact that skb_shared_info sits at the end of
skb->head, and we can use this room, if we convert bnx2x to new
build_skb() infrastructure.

skb_shared_info will be initialized after hardware finished its
transfert, so we can eventually overwrite the final padding.

Using build_skb() also reduces cache line misses in the driver, since we
use cache hot skb instead of cold ones. Number of in-flight sk_buff
structures is lower, they are recycled while still hot.

Performance results :

(820.000 pps on a rx UDP monothread benchmark, instead of 720.000 pps)

From 612a94d6f24eb2427eabf554392080302da664dd Mon Sep 17 00:00:00 2001
From: Rick Jones <rick.jones2@hp.com>
Date: Mon, 14 Nov 2011 08:13:25 +0000
Subject: [PATCH 0568/1958] Sweep the last of the active .get_drvinfo floors
 under ethernet/

This round of floor sweeping converts strncpy calls in various .get_drvinfo
routines to the preferred strlcpy.  It also does a modicum of other
cleaning in those routines.

Subject: [PATCH 0571/1958] IPv6 routing, NLM_F_* flag support: REPLACE and
 EXCL flags support, warn about missing CREATE flag

The support for NLM_F_* flags at IPv6 routing requests.

If NLM_F_CREATE flag is not defined for RTM_NEWROUTE request,
warning is printed, but no error is returned. Instead new route is
added. Later NLM_F_CREATE may be required for
new route creation.

Exception is when NLM_F_REPLACE flag is given without NLM_F_CREATE, and
no matching route is found. In this case it should be safe to assume
that the request issuer is familiar with NLM_F_* flags, and does really
not want route to be created.

Specifying NLM_F_REPLACE flag will now make the kernel to search for
matching route, and replace it with new one. If no route is found and
NLM_F_CREATE is specified as well, then new route is created.

Also, specifying NLM_F_EXCL will yield returning of error if matching
route is found.

From e2ebc8337d116acdc25469ec8547ae665f50a4c1 Mon Sep 17 00:00:00 2001
From: Stanislaw Gruszka <sgruszka@redhat.com>
Date: Mon, 24 Oct 2011 15:41:30 +0200
Subject: [PATCH 0575/1958] iwlegacy: rename iwl to il

iwl_legacy prefix result in long function names, what cause that we
have frequent line split and not readable code. Also iwl_foo symbols
are duplicated in iwlwifi driver, what is annoying when editing
kernel tree with cscope.

- * A double __ prefix before an access function means that state is checked

Subject: [PATCH 0584/1958] iwlegacy: mark poll bit as unlocked function

We do not take reg_lock during poll bit, so mark it such
using underscore.

+ * band_2
+ *
+ * A value of 0xff stored in the channel_map indicates that the channel
+ * is not supported by the hardware at all.
+ *
+ * A value of 0xfe in the channel_map indicates that the channel is not

+/*
+ * Rx theory of operation
+ *
+ * Driver allocates a circular buffer of Receive Buffer Descriptors (RBDs),
+ * each of which point to Receive Buffers to be filled by the NIC.  These get
+ * used not only for Rx frames, but for any command response or notification
+ * from the NIC.  The driver and NIC manage the Rx buffers by means
+ * of idxes into the circular buffer.
+ *
+ * Rx Queue Indexes
+ * The host/firmware share two idx registers for managing the Rx buffers.
+ *
+ * The READ idx maps to the first position that the firmware may be writing
+ * to -- the driver can read up to (but not including) this position and get
+ * good data.
+ * The READ idx is managed by the firmware once the card is enabled.
+ *
+ * The WRITE idx maps to the last position the driver has read from -- the
+ * position preceding WRITE is the last slot the firmware can place a packet.
+ *
+ * The queue is empty (no good data) if WRITE = READ - 1, and is full if
+ * WRITE = READ.
+ *
+ * During initialization, the host sets up the READ queue position to the first
+ * IDX position, and WRITE to the last (READ - 1 wrapped)
+ *
+ * When the firmware places a packet in a buffer, it will advance the READ idx
+ * and fire the RX interrupt.  The driver can then query the READ idx and
+ * process as many packets as possible, moving the WRITE idx forward as it
+ * resets the Rx queue buffers with new memory.
+ *
+ * The management in the driver is as follows:
+ * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free.  When
+ *   iwl->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
+ *   to replenish the iwl->rxq->rx_free.
+ * + In il_rx_replenish (scheduled) if 'processed' != 'read' then the
+ *   iwl->rxq is replenished and the READ IDX is updated (updating the
+ *   'processed' and 'read' driver idxes as well)
+ * + A received packet is processed and handed to the kernel network stack,
+ *   detached from the iwl->rxq.  The driver 'processed' idx is updated.
+ * + The Host/Firmware iwl->rxq is replenished at tasklet time from the rx_free
+ *   list. If there are no allocated buffers in iwl->rxq->rx_free, the READ
+ *   IDX is not incremented and iwl->status(RX_STALLED) is set.  If there
+ *   were enough free buffers and RX_STALLED is set it is cleared.
+ *
+ *
+ * Driver sequence:
+ *
+ * il_rx_queue_alloc()   Allocates rx_free

-/************************** EEPROM BANDS ****************************
- *
- * The il_eeprom_band definitions below provide the mapping from the
- * EEPROM contents to the specific channel number supported for each
- * band.
- *
- * For example, il_priv->eeprom.band_3_channels[4] from the band_3
- * definition below maps to physical channel 42 in the 5.2GHz spectrum.
- * The specific geography and calibration information for that channel
- * is contained in the eeprom map itself.
- *
- * During init, we copy the eeprom information and channel map
- * information into il->channel_info_24/52 and il->channel_map_24/52
- *
- * channel_map_24/52 provides the idx in the channel_info array for a
- * given channel.  We have to have two separate maps as there is channel
- * overlap with the 2.4GHz and 5.2GHz spectrum as seen in band_1 and
- * band_2
- *
- * A value of 0xff stored in the channel_map indicates that the channel
- * is not supported by the hardware at all.
- *
- * A value of 0xfe in the channel_map indicates that the channel is not
- * valid for Tx with the current hardware.  This means that
- * while the system can tune and receive on a given channel, it may not
- * be able to associate or transmit any frames on that
- * channel.  There is no corresponding channel information for that
- * entry.

-/************************** RX-FUNCTIONS ****************************/
-/*
- * Rx theory of operation
- *
- * Driver allocates a circular buffer of Receive Buffer Descriptors (RBDs),
- * each of which point to Receive Buffers to be filled by the NIC.  These get
- * used not only for Rx frames, but for any command response or notification
- * from the NIC.  The driver and NIC manage the Rx buffers by means
- * of idxes into the circular buffer.
- *
- * Rx Queue Indexes
- * The host/firmware share two idx registers for managing the Rx buffers.
- *
- * The READ idx maps to the first position that the firmware may be writing
- * to -- the driver can read up to (but not including) this position and get
- * good data.
- * The READ idx is managed by the firmware once the card is enabled.
- *
- * The WRITE idx maps to the last position the driver has read from -- the
- * position preceding WRITE is the last slot the firmware can place a packet.
- *
- * The queue is empty (no good data) if WRITE = READ - 1, and is full if
- * WRITE = READ.
- *
- * During initialization, the host sets up the READ queue position to the first
- * IDX position, and WRITE to the last (READ - 1 wrapped)
- *
- * When the firmware places a packet in a buffer, it will advance the READ idx
- * and fire the RX interrupt.  The driver can then query the READ idx and
- * process as many packets as possible, moving the WRITE idx forward as it
- * resets the Rx queue buffers with new memory.
- *
- * The management in the driver is as follows:
- * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free.  When
- *   iwl->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
- *   to replenish the iwl->rxq->rx_free.
- * + In il_rx_replenish (scheduled) if 'processed' != 'read' then the
- *   iwl->rxq is replenished and the READ IDX is updated (updating the
- *   'processed' and 'read' driver idxes as well)
- * + A received packet is processed and handed to the kernel network stack,
- *   detached from the iwl->rxq.  The driver 'processed' idx is updated.
- * + The Host/Firmware iwl->rxq is replenished at tasklet time from the rx_free
- *   list. If there are no allocated buffers in iwl->rxq->rx_free, the READ
- *   IDX is not incremented and iwl->status(RX_STALLED) is set.  If there
- *   were enough free buffers and RX_STALLED is set it is cleared.
- *
- *
- * Driver sequence:
- *
- * il_rx_queue_alloc()   Allocates rx_free
- * il_rx_replenish()     Replenishes rx_free list from rx_used, and calls
- *                            il_rx_queue_restock
- * il_rx_queue_restock() Moves available buffers from rx_free into Rx
- *                            queue, updates firmware pointers, and updates
- *                            the WRITE idx.  If insufficient rx_free buffers
- *                            are available, schedules il_rx_replenish
- *
- * -- enable interrupts --
- * ISR - il_rx()         Detach il_rx_bufs from pool up to the
- *                            READ IDX, detaching the SKB from the pool.
- *                            Moves the packet buffer from queue to rx_used.
- *                            Calls il_rx_queue_restock to refill any empty
- *                            slots.

- * Theory of operation
- *
- * A Tx or Rx queue resides in host DRAM, and is comprised of a circular buffer
- * of buffer descriptors, each of which points to one or more data buffers for
- * the device to read from or fill.  Driver and device exchange status of each
- * queue via "read" and "write" pointers.  Driver keeps minimum of 2 empty
- * entries in each circular buffer, to protect against confusing empty and full
- * queue states.
- *
- * The device reads or writes the data in the queues via the device's several
- * DMA/FIFO channels.  Each queue is mapped to a single DMA channel.
- *
- * For Tx queue, there are low mark and high mark limits. If, after queuing
- * the packet for Tx, free space become < low mark, Tx queue stopped. When
- * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
- * Tx queue resumed.

+ * Rx SRAM Control and Status Registers (RSCSR)
+ *
+ * These registers provide handshake between driver and 4965 for the Rx queue
+ * (this queue handles *all* command responses, notifications, Rx data, etc.
+ * sent from 4965 uCode to host driver).  Unlike Tx, there is only one Rx
+ * queue, and only one Rx DMA/FIFO channel.  Also unlike Tx, which can
+ * concatenate up to 20 DRAM buffers to form a Tx frame, each Receive Buffer
+ * Descriptor (RBD) points to only one Rx Buffer (RB); there is a 1:1
+ * mapping between RBDs and RBs.
+ *
+ * Driver must allocate host DRAM memory for the following, and set the
+ * physical address of each into 4965 registers:
+ *
+ * 1)  Receive Buffer Descriptor (RBD) circular buffer (CB), typically with 256
+ *     entries (although any power of 2, up to 4096, is selectable by driver).
+ *     Each entry (1 dword) points to a receive buffer (RB) of consistent size
+ *     (typically 4K, although 8K or 16K are also selectable by driver).
+ *     Driver sets up RB size and number of RBDs in the CB via Rx config
+ *     register FH49_MEM_RCSR_CHNL0_CONFIG_REG.
+ *
+ *     Bit fields within one RBD:
+ *     27-0:  Receive Buffer physical address bits [35:8], 256-byte aligned
+ *
+ *     Driver sets physical address [35:8] of base of RBD circular buffer
+ *     into FH49_RSCSR_CHNL0_RBDCB_BASE_REG [27:0].
+ *
+ * 2)  Rx status buffer, 8 bytes, in which 4965 indicates which Rx Buffers
+ *     (RBs) have been filled, via a "write pointer", actually the idx of
+ *     the RB's corresponding RBD within the circular buffer.  Driver sets
+ *     physical address [35:4] into FH49_RSCSR_CHNL0_STTS_WPTR_REG [31:0].
+ *
+ *     Bit fields in lower dword of Rx status buffer (upper dword not used
+ *     by driver; see struct il4965_shared, val0):
+ *     31-12:  Not used by driver
+ *     11- 0:  Index of last filled Rx buffer descriptor
+ *             (4965 writes, driver reads this value)
+ *
+ * As the driver prepares Receive Buffers (RBs) for 4965 to fill, driver must
+ * enter pointers to these RBs into contiguous RBD circular buffer entries,
+ * and update the 4965's "write" idx register,
+ * FH49_RSCSR_CHNL0_RBDCB_WPTR_REG.
+ *
+ * This "write" idx corresponds to the *next* RBD that the driver will make
+ * available, i.e. one RBD past the tail of the ready-to-fill RBDs within
+ * the circular buffer.  This value should initially be 0 (before preparing any
+ * RBs), should be 8 after preparing the first 8 RBs (for example), and must
+ * wrap back to 0 at the end of the circular buffer (but don't wrap before
+ * "read" idx has advanced past 1!  See below).
+ * NOTE:  4965 EXPECTS THE WRITE IDX TO BE INCREMENTED IN MULTIPLES OF 8.
+ *
+ * As the 4965 fills RBs (referenced from contiguous RBDs within the circular
+ * buffer), it updates the Rx status buffer in host DRAM, 2) described above,
+ * to tell the driver the idx of the latest filled RBD.  The driver must
+ * read this "read" idx from DRAM after receiving an Rx interrupt from 4965.
+ *
+ * The driver must also internally keep track of a third idx, which is the
+ * next RBD to process.  When receiving an Rx interrupt, driver should process
+ * all filled but unprocessed RBs up to, but not including, the RB
+ * corresponding to the "read" idx.  For example, if "read" idx becomes "1",
+ * driver may process the RB pointed to by RBD 0.  Depending on volume of
+ * traffic, there may be many RBs to process.
+ *
+ * If read idx == write idx, 4965 thinks there is no room to put new data.
+ * Due to this, the maximum number of filled RBs is 255, instead of 256.  To
+ * be safe, make sure that there is a gap of at least 2 RBDs between "write"
+ * and "read" idxes; that is, make sure that there are no more than 254
+ * buffers waiting to be filled.

-/**
- * Rx SRAM Control and Status Registers (RSCSR)
- *
- * These registers provide handshake between driver and 4965 for the Rx queue
- * (this queue handles *all* command responses, notifications, Rx data, etc.
- * sent from 4965 uCode to host driver).  Unlike Tx, there is only one Rx
- * queue, and only one Rx DMA/FIFO channel.  Also unlike Tx, which can
- * concatenate up to 20 DRAM buffers to form a Tx frame, each Receive Buffer
- * Descriptor (RBD) points to only one Rx Buffer (RB); there is a 1:1
- * mapping between RBDs and RBs.
- *
- * Driver must allocate host DRAM memory for the following, and set the
- * physical address of each into 4965 registers:
- *
- * 1)  Receive Buffer Descriptor (RBD) circular buffer (CB), typically with 256
- *     entries (although any power of 2, up to 4096, is selectable by driver).
- *     Each entry (1 dword) points to a receive buffer (RB) of consistent size
- *     (typically 4K, although 8K or 16K are also selectable by driver).
- *     Driver sets up RB size and number of RBDs in the CB via Rx config
- *     register FH49_MEM_RCSR_CHNL0_CONFIG_REG.
- *
- *     Bit fields within one RBD:
- *     27-0:  Receive Buffer physical address bits [35:8], 256-byte aligned
- *
- *     Driver sets physical address [35:8] of base of RBD circular buffer
- *     into FH49_RSCSR_CHNL0_RBDCB_BASE_REG [27:0].
- *
- * 2)  Rx status buffer, 8 bytes, in which 4965 indicates which Rx Buffers
- *     (RBs) have been filled, via a "write pointer", actually the idx of
- *     the RB's corresponding RBD within the circular buffer.  Driver sets
- *     physical address [35:4] into FH49_RSCSR_CHNL0_STTS_WPTR_REG [31:0].
- *
- *     Bit fields in lower dword of Rx status buffer (upper dword not used
- *     by driver; see struct il4965_shared, val0):
- *     31-12:  Not used by driver
- *     11- 0:  Index of last filled Rx buffer descriptor
- *             (4965 writes, driver reads this value)
- *
- * As the driver prepares Receive Buffers (RBs) for 4965 to fill, driver must
- * enter pointers to these RBs into contiguous RBD circular buffer entries,
- * and update the 4965's "write" idx register,
- * FH49_RSCSR_CHNL0_RBDCB_WPTR_REG.
- *
- * This "write" idx corresponds to the *next* RBD that the driver will make
- * available, i.e. one RBD past the tail of the ready-to-fill RBDs within
- * the circular buffer.  This value should initially be 0 (before preparing any
- * RBs), should be 8 after preparing the first 8 RBs (for example), and must
- * wrap back to 0 at the end of the circular buffer (but don't wrap before
- * "read" idx has advanced past 1!  See below).
- * NOTE:  4965 EXPECTS THE WRITE IDX TO BE INCREMENTED IN MULTIPLES OF 8.
- *
- * As the 4965 fills RBs (referenced from contiguous RBDs within the circular
- * buffer), it updates the Rx status buffer in host DRAM, 2) described above,
- * to tell the driver the idx of the latest filled RBD.  The driver must
- * read this "read" idx from DRAM after receiving an Rx interrupt from 4965.
- *
- * The driver must also internally keep track of a third idx, which is the
- * next RBD to process.  When receiving an Rx interrupt, driver should process
- * all filled but unprocessed RBs up to, but not including, the RB
- * corresponding to the "read" idx.  For example, if "read" idx becomes "1",
- * driver may process the RB pointed to by RBD 0.  Depending on volume of
- * traffic, there may be many RBs to process.
- *
- * If read idx == write idx, 4965 thinks there is no room to put new data.
- * Due to this, the maximum number of filled RBs is 255, instead of 256.  To
- * be safe, make sure that there is a gap of at least 2 RBDs between "write"
- * and "read" idxes; that is, make sure that there are no more than 254
- * buffers waiting to be filled.

Subject: [PATCH 0645/1958] mdio-gpio: Add reset functionality to mdio-gpio
 driver(v2).

This patch adds phy reset functionality to mdio-gpio driver. Now
mdio_gpio_platform_data has new member as function pointer which can be
filled at the bsp level for a callback from phy infrastructure. Also the
mdio-bitbang driver fills-in the reset function of mii_bus structure.

Without this patch the bsp level code has to takecare of the reseting
PHY's on the bus, which become bit hacky for every bsp and
phy-infrastructure is ignored aswell.

Subject: [PATCH 0646/1958] ath6kl: remove hw version related parameter defines

Having separate defines, in a different file, makes it difficult to read
the actual values. As we are just setting named fields in a struct
the defines don't make any sense anymore.

There are no functional changes, only moving of constants.

Subject: [PATCH 0651/1958] ath6kl: use hardware version names consistently

Part of ath6kl uses "REV3" style of naming hardware versions and elsewhere
"hw 2.1.1" is used instead for the same version. This is confusing, use
the latter term everywhere.

Subject: [PATCH 0656/1958] ath6kl: Clear WPS ctrl flag if zero length IE is
 received from cfg80211

Connect control flag CONNECT_WPS_FLAG has to be cleared
by default even if the driver receives zero length IE
from cfg80211.

Otherwise this flag would be always set after WPS exchange
which would lead wpa_supplicant to fail to connect with
the received WPS credentials. This issue is observed only
in OPEN security.

kvalo: use cfg80211 instead of CFG in the commit log

Subject: [PATCH 0657/1958] ath6kl: Fix AP mode operation after interface
 down/up

When operating AP interface is brough down the mode is reset to
STA. This STA will be reconfigured into AP mode when the interface
is brought up again. This sequence will be successful only when
change_virtual_intf() returns with no error, but there is a
check in this callback which does the type change only when
that interface is active. This callback does nothing more
than saving the new interface type to vif and wdev, so the
sanity check for interface state and wmi state is not necessary.
This makes the AP interface functional again after interface down/up.

Subject: [PATCH 0665/1958] e1000e: convert to real ndo_set_rx_mode

Commit afc4b13d (net: remove use of ndo_set_multicast_list in
drivers) changed e1000e to use the ndo_set_rx_mode entry point,
but didn't implement the unicast address programming
functionality. Implement it to achieve the ability to add unicast
addresses.

Subject: [PATCH 0666/1958] e1000e: Convert printks to pr_<level>

Based on the original patch from Joe Perches.
Use the current logging styles.
pr_<level> conversions are now prefixed with "e1000e:"
Correct a couple of defects where the trailing NTU may have
been printed on a separate line because of an interleaving
hex_dump.
Remove unnecessary uses of KERN_CONT and use single pr_info()s
to avoid any possible output interleaving from other modules.
Coalesce formats as appropriate.
Remove an extra space from a broken across lines
coalescing of "Link Status " and " Change".

-v2 Remove changes to Copyright string

Subject: [PATCH 0667/1958] ixgbe: fix LED blink logic to check for link

Previously the driver would force link without checking whether the link was
already established. This caused some inconsistencies in the LED blink rate.

Do not force link if link is already up.

From 876d2d6f6e60b1170f7ed664b9659def92b87be3 Mon Sep 17 00:00:00 2001
From: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
Date: Fri, 21 Oct 2011 20:01:34 +0000
Subject: [PATCH 0670/1958] igb: Convert printks to pr_<level>

Based on original patch from Joe Perches <joe@perches.com>

Use the current logging styles.

pr_<level> conversions are now prefixed with "igb: "

Correct a defect where the trailing NTU may have been printed
on a separate line because of an interleaving hex_dump.

Remove unnecessary uses of KERN_CONT and use single pr_info()s
to avoid any possible output interleaving from other modules.

Coalesce formats as appropriate.

-v2 fix-up to make checkpatch.pl compliant and remove change to
    the copyright line

Date: Wed, 9 Nov 2011 17:14:25 -0300
Subject: [PATCH 0673/1958] Bluetooth: Rename mgmt_inquiry_failed()

This patch renames the function mgmt_inquiry_failed() to
mgmt_start_discovery_failed(). This function is more related
to MGMT_OP_START_DISCOVERY command handling than to inquiry.
Besides, this functions will be reused by LE based discovery
procedures in case of failure.

This patches creates mgmt_stop_discovery_failed() which removes
pending MGMT_OP_STOP_DISCOVERY commands and sends proper command
status events.

This patch also fixes the MGMT_OP_STOP_DISCOVERY command leak in
case cancel inquiry fails.

Subject: [PATCH 0675/1958] Bluetooth: Add address type to mgmt_pair_device

The kernel needs to know whether it should connect to a device over
BR/EDR or over LE. This is particularly important in the future when
dual-mode device may be connectable also over LE. It is also important
if/when we decide to move the LE advertisement cache from the kernel
into user-space. Adding the type to the mgmt command also ensures
conformance with the latest mgmt API spec.

Subject: [PATCH 0678/1958] Bluetooth: Create a unique mgmt error code
 hierarchy

The management protocol uses a single byte for error codes (aka command
status). In some places this value is directly copied from HCI and in
other a POSIX error number is used. This makes it impossible for
user-space to uniquily decipher the meaning of an error.

To solve this issue a new mgmt-specific set of error codes is added
along with a conversion table for HCI status values.

Subject: [PATCH 0680/1958] Bluetooth: Pass all message parameters to
 mgmt_start_discovery

The mgmt_start_discovery command contains the type of discovery that
should be started so this should be passed to the start_discovery
function. This patch doesn't yet add any action depending on the type of
the requested discovery.

 consistent with emulated NICs

Add a new .bus_name to virtio_config_ops then modify virtio_net to
call through to it in an ethtool .get_drvinfo routine to report
bus_info in ethtool -i output which is consistent with other
emulated NICs and the output of lspci.

Subject: [PATCH 0692/1958] net: use jump_label for netstamp_needed

netstamp_needed seems a good candidate to jump_label conversion.

This avoids 3 conditional branches per incoming packet in fast path.

No measurable difference, given that these conditional branches are
predicted on modern cpus. Only a small icache reduction, thanks to the
unlikely() stuff.

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

This is the only place left where dev->features are directly
exposed to userspace.

I know checkpatch.pl complains about __ethtool_{get,set}_flags(), but
the code is easier to read this way.

From a19f2a6df28e0ccb4103b77cc17c03b62f4d573e Mon Sep 17 00:00:00 2001
From: =?UTF-8?q?Micha=C5=82=20Miros=C5=82aw?= <mirq-linux@rere.qmqm.pl>
Date: Tue, 15 Nov 2011 15:29:55 +0000
Subject: [PATCH 0698/1958] net: Define enum for net device features.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Define feature values by bit position instead of direct 2**i values
and force the values to be of type netdev_features_t.

Cleaned and extended from patch by Mahesh Bandewar <maheshb@google.com>:
+ added netdev_features_t casts
+ included bits under NETIF_F_GSO_MASK
+ moved feature #defines out of struct net_device definition

enabled by default. The check heuristics is altered a bit here,
so it hits other people than before. The default shouldn't be
trusted for performance-critical cases anyway.

For all other uses NETIF_F_NO_CSUM is equivalent to NETIF_F_HW_CSUM.

Subject: [PATCH 0704/1958] be2net: Fix TX queue create for Lancer

Lancer uses V1 version of TXQ create. This command needs interface
id for TX queue creation. Rearrange code such that tx queue create
is after interface create. As TXQ create is now called after MCC
ring create use MCC instead of MBOX.

Subject: [PATCH 0712/1958] team: replicate options on register

Since multiple team instances are putting defined options into their
option list, during register each option must be cloned before added
into list. This resolves uncool memory corruptions when using multiple
teams.

Subject: [PATCH 0713/1958] net: Add ethtool to mii advertisment conversion
 helpers

Translating between ethtool advertisement settings and MII
advertisements are common operations for ethernet drivers.  This patch
adds a set of helper functions that implements the conversion.  The
patch then modifies a couple of the drivers to use the new functions.

Subject: [PATCH 0722/1958] forcedeth: fix stats on hardware without extended
 stats support

This change makes sure that tx_packets/rx_bytes ifconfig counters are
updated even on NICs that don't provide hardware support for these
stats: they are now updated in software. For the sake of consistency,
we also now have tx_bytes updated in software (hardware counters
include ethernet CRC, and software doesn't account for it).

This reverts parts of:
 - "forcedeth: statistics optimization" (21828163b2)
 - "forcedeth: Improve stats counters" (0bdfea8ba8)
 - "forcedeth: remove unneeded stats updates" (4687f3f364)

Tested:
  pktgen + loopback (http://patchwork.ozlabs.org/patch/124698/)
  reports identical tx_packets/rx_packets and tx_bytes/rx_bytes.

Subject: [PATCH 0724/1958] net: new counter for tx_timeout errors in sysfs

This adds the /sys/class/net/DEV/queues/Q/tx_timeout attribute
containing the total number of timeout events on the given queue. It
is always available with CONFIG_SYSFS, independently of
CONFIG_RPS/XPS.

Credits to Stephen Hemminger for a preliminary version of this patch.

Tested:
  without CONFIG_SYSFS (compilation only)
  with sysfs and without CONFIG_RPS & CONFIG_XPS
  with sysfs and without CONFIG_RPS
  with sysfs and without CONFIG_XPS
  with defaults

Subject: [PATCH 0726/1958] forcedeth: allow to silence "TX timeout" debug
 messages

This adds a new module parameter "debug_tx_timeout" to silence most
debug messages in case of TX timeout. These messages don't provide a
signal/noise ratio high enough for production systems and, with ~30kB
logged each time, they tend to add to a cascade effect if the system
is already under stress (memory pressure, disk, etc.).

By default, the parameter is clear, meaning that only a single warning
will be reported.

Subject: [PATCH 0727/1958] forcedeth: implement ndo_get_stats64() API

This commit implements the ndo_get_stats64() API for forcedeth. Since
hardware stats are being updated from different contexts (process and
timer), this commit adds synchronization. For software stats, it
relies on the u64_stats_sync.h API.

Tested:
  - 16-way SMP x86_64 ->
    RX bytes:7244556582 (7.2 GB)  TX bytes:181904254 (181.9 MB)
  - pktgen + loopback: identical rx_bytes/tx_bytes and rx_packets/tx_packets

Subject: [PATCH 0729/1958] forcedeth: stats updated with a deferrable timer

Mark stats timer as deferrable: punctuality in waking the stats timer
callback doesn't matter much, as it is responsible only to avoid
integer wraparound.

We need at least 1 other timer to fire within 17s (fully loaded 1Gbps)
to avoid wrap-arounds. Desired period is still 10s.

Subject: [PATCH 0730/1958] IPV6 Fix a crash when trying to replace non
 existing route

This patch fixes a crash when non existing IPv6 route is tried to be changed.

When new destination node was inserted in middle of FIB6 tree, no relevant
sanity checks were performed. Later route insertion might have been prevented
due to invalid request, causing node with no rt info being left in tree.
When this node was accessed, a crash occurred.

Patch adds missing checks in fib6_add_1()

Subject: [PATCH 0737/1958] mac80211: remove crypto special case for auth
 frames

The shared key authentication frame that needs to be
encrypted (the third one in the shared key handshake)
is directly encrypted in ieee80211_send_auth and the
IEEE80211_TX_INTFL_DONT_ENCRYPT is set. All others
are not encrypted, so the only way to get to this is
erroneously on no-monitor AP side.

Remove the special case for authentication frames to
fix the AP shared key side when operating without
cooked monitor interfaces -- with cooked monitor the
IEEE80211_TX_INTFL_DONT_ENCRYPT also gets set, so we
never get here -- an AP never encrypts auth frames.

Without this patch, an AP operating in WEP mode with
my no-monitor patches would erroneously encrypt all
authentication frames, instead of none.

Subject: [PATCH 0739/1958] mac80211: Get rid of search loop for rate group
 index

Finding the group index for a specific rate is done by looping through
all groups and returning if the correct one is found. This code is
called for each tx'ed frame and thus it makes sense to reduce its
runtime.

Do this by calculating the group index by this formula based on the SGI
and HT40 flags as well as the stream number:

idx = (HT40 * 2 * MINSTREL_MAX_STREAMS) +
      (SGI * MINSTREL_MAX_STREAMS) +
      (streams - 1)

Hence, the groups are ordered by th HT40 flag first, then by the SGI
flag and afterwards by the number of used streams.

This should reduce the runtime of minstrel_ht_get_group_idx
considerable.

Subject: [PATCH 0744/1958] mac80211: call ieee80211_recalc_idle() after
 sending packets

Some drivers (e.g. ath9k) assume that it's safe to go into low-power mode
immediately after the idle state changes. To support that, mac80211 even
calls drv_flush() before that happens.
In some instances, mac80211 sent a packet right after recalculating the
idle state, this patch fixes that.

Subject: [PATCH 0748/1958] net: use jump_label to shortcut RPS if not setup

Most machines dont use RPS/RFS, and pay a fair amount of instructions in
netif_receive_skb() / netif_rx() / get_rps_cpu() just to discover
RPS/RFS is not setup.

Add a jump_label named rps_needed.

If no device rps_map or global rps_sock_flow_table is setup,
netif_receive_skb() / netif_rx() do a single instruction instead of many
ones, including conditional jumps.

jmp +0    (if CONFIG_JUMP_LABEL=y)

Subject: [PATCH 0754/1958] bnx2: switch to build_skb() infrastructure

This is very similar to bnx2x conversion, but bnx2 only requires 16bytes
alignement at start of the received frame to store its l2_fhdr, so goal
was not to reduce skb truesize (in fact it should not change after this
patch)

Using build_skb() reduces cache line misses in the driver, since we
use cache hot skb instead of cold ones. Number of in-flight sk_buff
structures is lower, they are more likely recycled in SLUB caches
while still hot.

Subject: [PATCH 0755/1958] net-forcedeth: fix possible stats inaccuracies on
 32b hosts

The software stats are updated from BH, this change ensures that 32b
UP hosts use appropriate protection.

Tested:
  - HW/SW stats consistent with pktgen (in particular tx=rx)
  - HW/SW stats consistent when tx/rx offloads disabled
  - no problem with+without lockdep (SMP 16-way)

ipv4: Remove all uses of LL_ALLOCATED_SPACE

The macro LL_ALLOCATED_SPACE was ill-conceived.  It applies the
alignment to the sum of needed_headroom and needed_tailroom.  As
the amount that is then reserved for head room is needed_headroom
with alignment, this means that the tail room left may be too small.

This patch replaces all uses of LL_ALLOCATED_SPACE in net/ipv4
with the macro LL_RESERVED_SPACE and direct reference to
needed_tailroom.

This also fixes the problem with needed_headroom changing between
allocating the skb and reserving the head room.

Subject: [PATCH 0758/1958] net: Remove all uses of LL_ALLOCATED_SPACE

net: Remove all uses of LL_ALLOCATED_SPACE

The macro LL_ALLOCATED_SPACE was ill-conceived.  It applies the
alignment to the sum of needed_headroom and needed_tailroom.  As
the amount that is then reserved for head room is needed_headroom
with alignment, this means that the tail room left may be too small.

This patch replaces all uses of LL_ALLOCATED_SPACE with the macro
LL_RESERVED_SPACE and direct reference to needed_tailroom.

This also fixes the problem with needed_headroom changing between
allocating the skb and reserving the head room.

Subject: [PATCH 0760/1958] packet: Add needed_tailroom to packet_sendmsg_spkt

packet: Add needed_tailroom to packet_sendmsg_spkt

While auditing LL_ALLOCATED_SPACE I noticed that packet_sendmsg_spkt
did not include needed_tailroom when allocating an skb.  This isn't
a fatal error as we should always tolerate inadequate tail room but
it isn't optimal.

This patch fixes that.

Subject: [PATCH 0770/1958] batman-adv: use orig_hash_find() instead of
 get_orig_node() in TT code

get_orig_node() tries to retrieve an orig_node object based on a mac address
and creates it if not present. This is not the wanted behaviour in the
translation table code as we don't want to create new orig_code objects but
expect a NULL pointer if the object does not exist.

Subject: [PATCH 0771/1958] batman-adv: fixed hash functions type to uint32_t
 instead of int

There are two reasons for this fix:
- the result of choose_orig() and vis_choose() is an index and therefore it can't
  be negative. Hence it is correct to make the return type unsigned too.

- sizeof(int) may not be the same on ALL the architectures. Since we plan to use
  choose_orig() as DHT hash function, we need to guarantee that, given the same
  argument, the result is the same. Then it is correct to explicitly express
  the size of the return type (and the second argument). Since the expected
  length is currently 4, uint32_t is the most convenient choice.

Subject: [PATCH 0772/1958] batman-adv: directly write tt entries without
 buffering

When the translation tables (global and local) are written for debugfs,
it is not neccesary to allocate a buffer, we can directly use
seq_printf() to print them out.

This might actually be safer if the table changes between size
calculation and traversal, and we can't estimate the required size
wrong.

Subject: [PATCH 0776/1958] batman-adv: create a common substructure for
 tt_global/local_entry

Several functions in the translation table management code assume that the
tt_global_entry and tt_local_entry structures have the same initial fields such
as 'addr' and 'hash_entry'. To improve the code readability and to avoid
mistakes in later changes, a common substructure that substitute the shared
fields has been introduced (struct tt_common_entry).

Thanks to this modification, it has also been possible to slightly reduce the
code length by merging some functions like compare_ltt/gtt() and
tt_local/global_hash_find()

Subject: [PATCH 0778/1958] batman-adv: generalise tt_local_reset_flags()

The tt_local_reset_flags() is actually used for one use case only. It is not
generalised enough to be used indifferent situations. This patch make it general
enough in order to let other code use it whenever a flag set is requested over
the whole hash table (passed as parameter). The function is now called
tt_set_flags()

Subject: [PATCH 0780/1958] batman-adv: use unregister_netdevice() when
 softif_create fails

When entering softif_create(), the rtnl lock has already been acquired
by store_mesh_iface().
(store_mesh_iface() -> hardif_enable_interface() -> softif_create)

In case of an error, we should therefore call unregister_netdevice()
instead of unregister_netdev().

unregister_netdev() tries to acquire the rtnl lock itself and deadlocks
in this situation. unregister_netdevice() assumes that the rtnl lock
is already been held.

and they all share the same checks and handling. This
restructures the handling of the two Confirm responses
in preperation for the second two.

Use queue instead of stack discipline for device list. When processing
dev_list with list_for_each* devices will be prosessed in order they
were added (Usually BR/EDR first and AMP later).

Also output from hciconfig looks nicer :-)

Subject: [PATCH 0788/1958] ath6kl: Remove modparam multi_norm_if_support

This modparam was introduced to enable non-p2p mode operation
on two virtual interfaces. It does not seem to be necessary to
have a separate module parameter to do that. Instead, this option
can be enabled when any one of the interfaces is not going to be
used for p2p (ath6kl_p2p).

Subject: [PATCH 0792/1958] ath6kl: Use mutex to protect dma buffer in sync
 read write

Firmware crashes while starting Soft AP in 32 bit x86 platform.
The reason is that the single dma buffer (ar_sdio->dma_buffer)
is used in ath6kl_sdio_read_write_sync() for unaligned buffer
handling and this function is called in the multiple context
at the same time. So, finally hits dma buffer corruption and
firmware crash.

Mutex is used to protect dma buffer to avoid data corruption.
Spin lock can not used to fix this issue since mmc stack
read/write calls may for sleep.

Observed this issue with recently commited patch
"ath6kl: Claim sdio function only at appropriate places"
861dd058f495973c7ad2a44b8f68f3cc05733eab

about what it protects

Subject: [PATCH 0795/1958] ksz884x: Use kzalloc rather than kmalloc followed
 by memset with 0

This considers some simple cases that are common and easy to validate
Note in particular that there are no ...s in the rule, so all of the
matched code has to be contiguous

Subject: [PATCH 0799/1958] tg3: switch to build_skb() infrastructure

This is very similar to bnx2x conversion, but simpler since no special
alignement is required, so goal was not to reduce skb truesize.

Using build_skb() reduces cache line misses in the driver, since we
use cache hot skb instead of cold ones. Number of in-flight sk_buff
structures is lower, they are more likely recycled in SLUB caches
while still hot.

Subject: [PATCH 0800/1958] cfg80211: process regulatory DFS region for
 countries

The wireless-regdb now has support for mapping a country to
one DFS region. CRDA sends this to us now so process it
so we can provide that hint to drivers. This will later be
used by code for processing DFS in a way that meets the
criteria for the DFS region the country belongs to.

Subject: [PATCH 0802/1958] ath9k: trivial: reorder rx_tasklet processing

DFS events are reported as PHY errors and need to be processed
with a correct timestamp set before ath9k_skb_preprocess() is
called and the frame is possibly dropped.

This patch puts the rxs->mactime calculation before the skb
is preprocessed to prepare for DFS event reporting.

Subject: [PATCH 0803/1958] mac80211: use skb list for fragments

We are currently linking the skbs by using skb->next
directly. This works, but the preferred way is to use
a struct sk_buff_head instead. That also prepares for
passing that to drivers directly.

While at it I noticed we calculate the duration for
fragments twice -- remove one of them.

This just prepares for passing the entire fragment
list to the driver. No significant changes, but the
TX throughput is calculated slightly differently
now and we blink only once for each MSDU.

Subject: [PATCH 0806/1958] mac80211: transmit fragment list to drivers

Drivers can usually handle fragmented packets
much easier when they get the entire list of
fragments at once. The only thing they need to
do is keep enough space on the queues for up
to ten fragments of a single MSDU.

This allows them to implement this with a new
operation tx_frags.

User space might want to test if driver supports testmode. Adding testmode
to the list of supported commands makes this easier.

I omitted testmode_dump() in purpose. I assume all drivers implementing
testmode_dump() will also implement testmode_cmd().

Subject: [PATCH 0810/1958] rtlwifi: rtl8192cu: Change firmware upload to use
 block writes

Driver rtl8192cu writes the firmware with 32-bit asynchronous writes. This
design is OK for USB 2.0 adapters, but the current implementation of
xhcu-hcd has a limited ring size, which is exceeded. By converting to
synchronous block writes, this error is avoided.

Subject: [PATCH 0811/1958] rtlwifi: rtl8192cu: Fix endianian issues

Driver rtlwifi fails on a big-endian host.

These changes have been tested on a Mac PowerBook G4, which has
a PPC processor.

Although this patch touches some of the code that will affect endian
issues on PCI hardware through drivers rtl8192ce, rtl8192se, and
rtl8192de, these have not been tested due to lack of suitable hardware.

Subject: [PATCH 0819/1958] iwl-debug: Shrink object by using dev_err and
 deduplicating formats

Using dev_err instead of dev_printk(KERN_ERR uses fewer
arguments and is a bit smaller.

Deduplicating formats used by IWL_DEBUG_QUIET_RFKILL also
makes the object a bit smaller.

Neatened the macros, used ##__VA_ARGS__.

Subject: [PATCH 0820/1958] mac80211: minor cleanup to mesh state locking

First time I tried smatch, and it says:
mesh_hwmp.c +870 mesh_queue_preq(21) error: double lock 'bottom_half:'
mesh_hwmp.c +873 mesh_queue_preq(24) error: double unlock 'bottom_half:'
mesh_hwmp.c +886 mesh_queue_preq(37) error: double unlock 'bottom_half:'

Which is indeed true -- there's no point in disabling BHs
again if we just did that a few lines earlier, so remove.

Currently mac80211 implements these for all devices,
but given restrictions of some devices that isn't
really true, so prepare for being able to remove the
capability for some mac80211 devices.

 parsing logic to cfg80211"

No other driver ever ended up using this, and
the commit forgot to move the prototype so no
driver could have used it. Revert it, if any
driver shows up and needs it it can be moved
again, but until then it's more efficient to
have it in mac80211 where the only user is.

From 7e7c8926b2f4e3453b8aeb39cd814d2af3fec24f Mon Sep 17 00:00:00 2001
From: Ben Greear <greearb@candelatech.com>
Date: Fri, 18 Nov 2011 11:31:59 -0800
Subject: [PATCH 0824/1958] wireless: Support ht-capabilities over-rides.

This allows users to disable features such as HT, HT40,
and to modify the MCS, AMPDU, and AMSDU settings for
drivers that support it.

The MCS, AMPDU, and AMSDU features that may be disabled are
are reported in the phy-info netlink message as a mask.

Attemping to disable features that are not supported will
take no affect, but will not return errors.  This is to aid
backwards compatibility in user-space apps that may not be
clever enough to deal with parsing the the capabilities mask.

This patch only enables the infrastructure.  An additional
patch will enable the feature in mac80211.

From ef96a84202ccfb48a4569256ffba45e32308f7ee Mon Sep 17 00:00:00 2001
From: Ben Greear <greearb@candelatech.com>
Date: Fri, 18 Nov 2011 11:32:00 -0800
Subject: [PATCH 0825/1958] mac80211: Support ht-cap over-rides.

This implements ht-cap over-rides for mac80211 drivers.
HT may be disabled, making an /a/b/g/n station act like an
a/b/g station.  HT40 may be disabled forcing the station to
be HT20 even if the AP and local hardware support HT40.

MAX-AMSDU may be disabled.
AMPDU-Density may be increased.
AMPDU-Factor may be decreased.

This has been successfully tested with ath9k using patched
wpa_supplicant and iw.

In the past, it was fine to simply call
dev_kfree_skb when it was impossible to
transmit a skb. However, with the new
tx status API:
"mac80211: implement wifi TX status"
Every loose skb needs to be handed back
to mac80211.

Subject: [PATCH 0832/1958] carl9170: use ieee80211_free_txskb

In the past, it was fine to simply call
dev_kfree_skb when it was impossible to
transmit a skb. However, with the new
tx status API:
"mac80211: implement wifi TX status"
Every loose skb needs to be handed back
to mac80211.

Subject: [PATCH 0833/1958] cfg80211: work around a sparse issue

sparse reports:
net/wireless/util.c:499:30: error: cannot size expression
net/wireless/util.c:503:30: error: cannot size expression

This is evidently due to the EXPORT_SYMBOL() of the
bridge_tunnel_header and rfc1042 header variables.
Move them to the end of the file to work around the
sparse issue. The error itself from sparse can be
ignored safely, but since sparse stops parsing at
errors, other issues after this would go undetected.

Subject: [PATCH 0834/1958] mac80211: fix RCU warnings in mesh

Sparse RCU checking reports two warnings in the mesh
path table code. These are due to questionable uses of
rcu_dereference.

To fix the first one, get rid of mesh_gate_add() and
just make mesh_path_add_gate() do the correct deref.

To fix the second one, simply remove rcu_dereference()
in mesh_gate_del() -- it already gets a proper pointer
as indicated by the prototype (no __rcu annotation)
and confirmed by the code.

Subject: [PATCH 0835/1958] netfilter: use jump_label for nf_hooks

On configs where CONFIG_JUMP_LABEL=y, we can replace in fast path a
load/compare/conditional jump by a single jump with no dcache reference.

Jump target is modified as soon as nf_hooks[pf][hook] switches from
empty state to non empty states. jump_label state is kept outside of
nf_hooks array so has no cost on cpu caches.

This patch removes the test on CONFIG_NETFILTER_DEBUG : No need to call
nf_hook_slow() at all if nf_hooks[pf][hook] is empty, this didnt give
useful information, but slowed down things a lot.

Subject: [PATCH 0838/1958] tg3: Fix advertisement handling

Commit 28011cf19b (net: Add ethtool to mii advertisment conversion
helpers) added a helper function ethtool_adv_to_mii_100bt() and
tg3_copper_is_advertising_all(), tg3_phy_autoneg_cfg() were
modified to use this.
Before that commit, ethtool to mii advertisement conversion was
done wrt speed, but now pause operation is also taken account.
So, in tg3_copper_is_advertising_all(), below condition becomes
true and this makes link up fails.

	if ((adv_reg & ADVERTISE_ALL) != all_mask)
		return 0;

To fix this add ADVERTISE_ALL bit and operation to cap speed,
and change default advertisement not including ADVERTISED_Pause.

Subject: [PATCH 0839/1958] net: add network priority cgroup infrastructure
 (v4)

This patch adds in the infrastructure code to create the network priority
cgroup.  The cgroup, in addition to the standard processes file creates two
control files:

1) prioidx - This is a read-only file that exports the index of this cgroup.
This is a value that is both arbitrary and unique to a cgroup in this subsystem,
and is used to index the per-device priority map

2) priomap - This is a writeable file.  On read it reports a table of 2-tuples
<name:priority> where name is the name of a network interface and priority is
indicates the priority assigned to frames egresessing on the named interface and
originating from a pid in this cgroup

This cgroup allows for skb priority to be set prior to a root qdisc getting
selected. This is benenficial for DCB enabled systems, in that it allows for any
application to use dcb configured priorities so without application modification

+Network priority cgroup
+-------------------------
+
+The Network priority cgroup provides an interface to allow an administrator to
+dynamically set the priority of network traffic generated by various
+applications
+
+Nominally, an application would set the priority of its traffic via the
+SO_PRIORITY socket option.  This however, is not always possible because:
+
+1) The application may not have been coded to set this value
+2) The priority of application traffic is often a site-specific administrative
+   decision rather than an application defined one.
+
+This cgroup allows an administrator to assign a process to a group which defines
+the priority of egress traffic on a given interface. Network priority groups can
+be created by first mounting the cgroup filesystem.
+
+# mount -t cgroup -onet_prio none /sys/fs/cgroup/net_prio
+
+With the above step, the initial group acting as the parent accounting group
+becomes visible at '/sys/fs/cgroup/net_prio'.  This group includes all tasks in
+the system. '/sys/fs/cgroup/net_prio/tasks' lists the tasks in this cgroup.
+
+Each net_prio cgroup contains two files that are subsystem specific
+
+net_prio.prioidx
+This file is read-only, and is simply informative.  It contains a unique integer
+value that the kernel uses as an internal representation of this cgroup.
+
+net_prio.ifpriomap
+This file contains a map of the priorities assigned to traffic originating from
+processes in this group and egressing the system on various interfaces. It
+contains a list of tuples in the form <ifname priority>.  Contents of this file
+can be modified by echoing a string into the file using the same tuple format.
+for example:
+
+echo "eth0 5" > /sys/fs/cgroups/net_prio/iscsi/net_prio.ifpriomap
+
+This command would force any traffic originating from processes belonging to the
+iscsi net_prio cgroup and egressing on interface eth0 to have the priority of
+said traffic set to the value 5. The parent accounting group also has a
+writeable 'net_prio.ifpriomap' file that can be used to set a system default
+priority.
+
+Priorities are set immediately prior to queueing a frame to the device
+queueing discipline (qdisc) so priorities will be assigned prior to the hardware
+queue selection being made.
+
+One usage for the net_prio cgroup is with mqprio qdisc allowing application
+traffic to be steered to hardware/driver based traffic classes. These mappings
+can then be managed by administrators or other networking protocols such as
+DCBX.

Compiler doesn't know that memcmp() branch doesn't trigger for IPv4.
Also, pass addresses by value -- they fit into register.

Subject: [PATCH 0842/1958] CDC NCM: Use kzalloc rather than kmalloc followed
 by memset with 0

This considers some simple cases that are common and easy to validate
Note in particular that there are no ...s in the rule, so all of the
matched code has to be contiguous

The semantic patch that makes this change is available
in scripts/coccinelle/api/alloc/kzalloc-simple.cocci.

Subject: [PATCH 0844/1958] tg3: Adjust BD replenish thresholds

The BD replenish thresholds for the 57765 and newer ASIC revs are a
little strict.  They were tuned for a mode that is currently unused.
This patch relaxes the thresholds so that they are set to values more
inline with the resources available.

Future devices may or may not be capable of supporting larger rx
producer rings.  This patch changes the code so that this flag is set on
an ASIC rev to ASIC rev basis.  Also, this patch changes a place where
the LRG_PROD_RING_CAP flag was not controlling how the rx standard
producer ring size was set.

Subject: [PATCH 0851/1958] atm: Allow MSG_PEEK for atm sockets

Now that the vcc backends do the right thing with respect the receive
queue on registration, allow MSK_PEEK for atm sockets.

This allows a userspace program to inspect the packets and decide what
backend to use to handle them.

From 84b405011166e663fe9ef56c29b1d76f59b35568 Mon Sep 17 00:00:00 2001
From: Rick Jones <rick.jones2@hp.com>
Date: Mon, 21 Nov 2011 10:54:05 +0000
Subject: [PATCH 0853/1958] Sweep away N/A fw_version dustbunnies from the
 .get_drvinfo routine of a number of drivers

Per discussion with Ben Hutchings and David Miller, go through and
remove assignments of "N/A" to fw_version in various drivers'
.get_drvinfo routines.  While there clean-up some use of bare
constants and such.

From 1f2149c1df50c8c712950872675f46e6e44629f0 Mon Sep 17 00:00:00 2001
From: Eric Dumazet <eric.dumazet@gmail.com>
Date: Tue, 22 Nov 2011 10:57:41 +0000
Subject: [PATCH 0854/1958] net: remove netdev_alloc_page and use __GFP_COLD

Given we dont use anymore the struct net_device *dev argument, and this
interface brings litle benefit, remove netdev_{alloc|free}_page(), to
debloat include/linux/skbuff.h a bit.

(Some drivers used a mix of these interfaces and alloc_pages())

When allocating a page given to device for DMA transfer (device to
memory), it makes sense to use a cold one (__GFP_COLD)

Subject: [PATCH 0855/1958] netprio_cgroup: Fix build break

I broke the build with the addition of netprio_cgroups if CONFIG_CGROUPS=n.
This patch corrects it by moving the offending struct into an ifdef
CONFIG_CGROUPS block.  Also clean up a few needless defines and inline functions
that don't get called if CONFIG_CGROUPS isn't defined while Im at it.

Subject: [PATCH 0857/1958] net: treewide use of RCU_INIT_POINTER

rcu_assign_pointer(ptr, NULL) can be safely replaced by
RCU_INIT_POINTER(ptr, NULL)

(old rcu_assign_pointer() macro was testing the NULL value and could
omit the smp_wmb(), but this had to be removed because of compiler
warnings)

Subject: [PATCH 0859/1958] ath6kl: use a larger buffer for debug output

The return value of snprintf() is the number of bytes which would
have been copied if there was enough space, but we want the number of
bytes actually copied.  The scnprintf() function does this.

Also in theory, a %u can take take 10 digits so we may as well make
the buffer larger as well.

Subject: [PATCH 0864/1958] iwlagn: remove calibration knowledge

The init microcode knows very well which calibrations
are required and sends us results for those that are.
Consequently, we can just send all of those to the RT
uCode again.

The problem with having the driver know about this is
that it is a uCode feature, not a hardware feature so
the config is completely unsuitable.

The only thing we need to check is whether the device
needs crystal calibration or not, add a new parameter
to the configuration for that.

This makes new uCode work on 6000 series devices.

From f02c2fd383f4c771c75daf391abdbdcb88848439 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Thu, 17 Nov 2011 08:51:57 -0800
Subject: [PATCH 0865/1958] iwlagn: dynamically allocate & reflect calibration
 data

This makes handling the calibration data more generic
and no longer requires updating IWL_CALIB_MAX when a
new uCode comes with more calibration packets. Since
we just copy the data back, there's also no need for
understanding which calibration we received -- we can
just reflect it back to the runtime uCode.

Subject: [PATCH 0866/1958] iwlagn: allow up to uCode API 6 for 6000 devices

Since the uCode hasn't been released (yet?),
warn only if using older than API 4, but load
anything up to API 6.

Let's just log the options during load time; so there were be no confusion.

From 98e673080bd90b9338428be92dd3597798aac3ed Mon Sep 17 00:00:00 2001
From: Ben Hutchings <ben@decadent.org.uk>
Date: Fri, 25 Nov 2011 14:36:19 +0000
Subject: [PATCH 0873/1958] mv88e6xxx: Combine mv88e6131 and mv88e612_61_65
 drivers

These drivers share a lot of code, so if we make them modular they
should be built into the same module.  Therefore, link them together
and merge their respective module init and exit functions.

Subject: [PATCH 0875/1958] dsa: Allow core and drivers to be built as modules

Change the kconfig types to tristate and adjust the condition for
declaring net_device::dsa_ptr to allow for this.

Adjust the makefile so that if NET_DSA_MV88E6123_61_65=y and
NET_DSA_MV88E6131=m or vice versa then both drivers are built-in.  We
could leave these options as bool and make NET_DSA_MV88E6XXX a
user-selected option, but that would break existing configurations.

Subject: [PATCH 0878/1958] be2net: Move to new SR-IOV implementation in Lancer

SR-IOV implementation is Lancer has changed in following ways -
1)PF driver assigns one MAC addresses for VF using COMMON_SET_IFACE_MAC_LIST.
2)VF driver queries its MAC address using COMMON_GET_IFACE_MAC_LIST command
and assigns it to its interface.

Subject: [PATCH 0879/1958] be2net: Fix error recovery paths

When TX queues are created again after error recovery,
netif_set_real_num_tx_queues() is invoked to update number of real
TX queues created. rtnl lock needs to be held when invoking this routine.

Subject: [PATCH 0883/1958] eeprom_93cx6: Add data direction control.

Some devices need to know if the data is to be output or read, so add a
data direction into the eeprom structure to tell the driver whether the
data line should be driven.

The user in this case is the Micrel KS8851 which has a direction
control for the EEPROM data line and thus needs to know whether
to drive it (writing) or to tristate it for receiving.

Subject: [PATCH 0885/1958] KSZ8851-SNL: Add support for EEPROM MAC address

Add support for reading the MAC address from the system registers if there
is an EEPROM present. This involves caching the KS_CCR register for later
use (will also be useful for ETHTOOL support) and adding a print to say
that there is an EEPROM present.

Subject: [PATCH 0886/1958] KSZ8851-SNL: Fix MAC address change problem

When device is off it is under power saving mode. Changing the MAC address
in that situation will result in the device not communicating as the first
write to the MAC address register is not executed.

Subject: [PATCH 0895/1958] net/mlx4: fix UDP RSS related settings

Using RSS which takes into account UDP headers is controlled by
a module param, fix the setting of the HW RSS context to align
with that scheme. So far it was uncoditionally allowing hashing
on the UDP headers.

 truncates bits from constant value

the MLX4_EN_WOL_DO_MODIFY flag which is defined through enum targets
bit 63, this triggers a "cast truncate bits from constant value
(8000000000000000 becomes 0)" warning from sparse, fix that by using

Allow callers to decide whether an ACK is a duplicate ACK. This is a
prerequisite to allowing fastretrans_alert to be called from new
contexts, such as the no_queue and old_ack code paths, from which we
have extra info that tells us whether an ACK is a dupack.

The bug: Senders ignored DSACKs after recovery when there were no
outstanding packets (a common scenario for HTTP servers).

The change: when there are no outstanding packets (the "no_queue" goto
label), call tcp_fastretrans_alert() in order to use DSACKs to undo
congestion window reductions.

Other patches in this series will provide other changes that are
necessary to fully fix this problem.

Subject: [PATCH 0903/1958] tcp: use SACKs and DSACKs that arrive on ACKs below
 snd_una
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The bug: When the ACK field is below snd_una (which can happen when
ACKs are reordered), senders ignored DSACKs (preventing undo) and did
not call tcp_fastretrans_alert, so they did not increment
prr_delivered to reflect newly-SACKed sequence ranges, and did not
call tcp_xmit_retransmit_queue, thus passing up chances to send out
more retransmitted and new packets based on any newly-SACKed packets.

The change: When the ACK field is below snd_una (the "old_ack" goto
label), call tcp_fastretrans_alert to allow undo based on any
newly-arrived DSACKs and try to send out more packets based on
newly-SACKed packets.

Other patches in this series will provide other changes that are
necessary to fully fix this problem.

Subject: [PATCH 0904/1958] tcp: allow undo from reordered DSACKs

Previously, SACK-enabled connections hung around in TCP_CA_Disorder
state while snd_una==high_seq, just waiting to accumulate DSACKs and
hopefully undo a cwnd reduction. This could and did lead to the
following unfortunate scenario: if some incoming ACKs advance snd_una
beyond high_seq then we were setting undo_marker to 0 and moving to
TCP_CA_Open, so if (due to reordering in the ACK return path) we
shortly thereafter received a DSACK then we were no longer able to
undo the cwnd reduction.

The change: Simplify the congestion avoidance state machine by
removing the behavior where SACK-enabled connections hung around in
the TCP_CA_Disorder state just waiting for DSACKs. Instead, when
snd_una advances to high_seq or beyond we typically move to
TCP_CA_Open immediately and allow an undo in either TCP_CA_Open or
TCP_CA_Disorder if we later receive enough DSACKs.

Other patches in this series will provide other changes that are
necessary to fully fix this problem.

Subject: [PATCH 0905/1958] tcp: skip cwnd moderation in TCP_CA_Open in
 tcp_try_to_open

The problem: Senders were overriding cwnd values picked during an undo
by calling tcp_moderate_cwnd() in tcp_try_to_open().

The fix: Don't moderate cwnd in tcp_try_to_open() if we're in
TCP_CA_Open, since doing so is generally unnecessary and specifically
would override a DSACK-based undo of a cwnd reduction made in fast
recovery.

Subject: [PATCH 0912/1958] ath9k: improve ath_tx_aggr_stop to avoid TID stuck
 in cleanup state

When tx agg is being stopped TID is flushed using ath_tx_flush_tid. It
is possible that ath_tx_flush_tid completelly flushes TID (if all
packets in this TID have already been retried). If this happened
ath_tx_aggr_stop would leave TID in cleanup state permanently.
Fix this by making ath_tx_flush_tid remove AGGR_ADDBA_COMPLETE and
AGGR_CLEANUP flags from TID status if TID is empty.

Subject: [PATCH 0913/1958] ath9k_hw: Fix minimum CTL power for each runtime
 mode

The conformance test limits (CTL) for each regulatory domains
(FCC/ETSI/MKK) are programmed for each runtime modes (11B,11G,
HT20 and HT40) in EEPROM. The lowest ctledge power value of a
particular running mode should not be used while computing
ctledge power for a different running mode.(i.e 11G's min ctledge
power should not be used while computing ctledge power for HT20).

Currently, the code does not handle this properly which would
result in incorrect txpowers in certain cases. So reset the
twiceMaxEdgePower to the default while computing min ctlegepower
for every mode.

In two places the next pointer was used to process a sk_buff chain
but it will always get a single sk_buff so this has been removed.

Subject: [PATCH 0918/1958] brcm80211: fmac: separate receiving skb chain from
 other receive path

In the receive path the buffer used to store the receive data from the
device can be a chain of sk_buff. It has been separated to allow the
use of skb queues.

Subject: [PATCH 0919/1958] brcm80211: fmac: remove width parameter from
 brcmf_sdioh_request_buffer

The function brcmf_sdioh_request_buffer() was requiring a parameter in
its prototype that was not used within the function. It has been
removed consequently.

Subject: [PATCH 0920/1958] brcm80211: fmac: simplify the
 brcmf_sdioh_request_buffer() function

The function is only called with sk_buff parameter being non-zero so
the prototype does not need to support passing a char buffer any longer.
When the function is called with a NULL sk_buff parameter it returns
-EINVAL now.

The nvram file contains info for firmware which varies with different
hardware designs. Use more common firmware/nvram file names instead
of those in Linux firmware repository to avoid misunderstanding.

Subject: [PATCH 0924/1958] brcm80211: fmac: remove alignment check from
 brcmf_sdioh_request_buffer()

The check for alignment is not valid anymore and can be removed. The
function is collapsed with brcmf_sdioh_request_packet() as a consequence
because it did not add much functionality any longer.

Subject: [PATCH 0926/1958] brcm80211: fmac: discard packet received when net
 device not registered

A new feature in the dongle firmware requires a handshake during
firmware intialization. The request is sent in event packets which the
host driver is not able to handle before any net device registered.
Discard those packets as the context for handling it is missing.
The initialization handler will be added as part of feature support

Subject: [PATCH 0931/1958] brcm80211: fmac: introduce common bus interface
 struct brcmf_bus

struct brcmf_bus will contain function porinter, bus specific
private structure pointer and interface context of generic layer
and bus layer. It will be the only shared structure between generic
and bus layer. This patch is part of fullmac bus interface
refactoring.

Subject: [PATCH 0932/1958] brcm80211: fmac: move busstate to struct brcmf_bus

busstate keeps track of the bus (USB/SDIO) status and is used by
both generic layer and bus layer. Move it to brcmf_bus helps to clean
up the interface. This patch is part of fullmac bus interface
refactoring.

Subject: [PATCH 0934/1958] brcm80211: fmac: change function bus_rxctl
 parameter

brcmf_sdbrcm_bus_rxctl acts as an interface function of bus layer.
Change parameter from struct brcmf_sdio to device pointer in order to
provide a more compatible interface for different bus layers. This
is part of the fullmac bus interface refactoring.

brcmf_bus_get_device is no longer necessary. Use dongle device pointer
saved in brcmf_pub directly. This is part of the fullmac bus interface
refactoring.

Subject: [PATCH 0940/1958] mac80211: timeout tx agg sessions in way similar to
 rx agg sessions

  Currently tx aggregation is not being timed out even if timeout is
specified when aggregation is opened. Tx tid stays active until delba
arrives from recipient (i.e. recipient times out tid when it is
inactive).
  The problem with this approach is that delba can get lost in the air
and tx tid will stay perpetually opened on the originator while closed
on recipient thus all data sent via this tid will be lost.
  This patch implements tx tid timeouting in way very similar to rx tid
timeouting.

 drivers

This fixes frequent WARN_ONs when using AP VLAN + aggregation, as these vifs
are virtual and not registered with drivers.
Use sta_info_get_bss instead of sta_info_get in aggregation callbacks, so
that these callbacks can find the station entry when called with the AP vif.

Subject: [PATCH 0944/1958] rtlwifi: Fix incorrect return of IRQ_HANDLED

The recent discussion regarding an incorrect return of IRQ_HANDLED
from rt2800pci caused me to look at this PCI interrupt routine. I
discovered that changes were needed.

Subject: [PATCH 0945/1958] rt2x00: Pass BlockAck and BlackAckReq frames to
 mac80211 in monitor mode

Previously BlockAcks were always dropped by the rt2800 hardware while
BlockAckReqs were always accepted. However, both are only useful on
monitor interfaces at the moment and both are control frames. So
pass them up when mac80211 sets FIF_CONTROL.

Subject: [PATCH 0946/1958] mac80211: fix TX warning

Emmanuel reported that my previous patches to enable
handing all fragments to drivers at once triggered
the warning that the SKB queue wasn't empty. This is
happening when we actually queue up some frames and
don't hand them to the driver (queues are stopped).

The reason for it is that my code that splices the
frame(s) over to the pending queue didn't re-init
the local queue, so skb_queue_empty() was false. Fix
this by using the _init versions of the splicing.

Also, convert the warning to WARN_ON_ONCE.

 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,

Subject: [PATCH 0952/1958] mac80211: failed forwarded mesh frame addressing

Don't write the TA until next hop is actually known, since we might need
the original TA for sending a PERR. Previously we would send a PERR to
ourself if path resolution for a forwarded frame failed.

Subject: [PATCH 0954/1958] mac80211: fix forwarded mesh frame queue mapping

We can't rely on ieee80211_select_queue() to do its job at this point
since the skb->protocol is not yet known. Instead, factor out and reuse
the queue mapping logic for injected frames.

Also, to mitigate congestion, forwarded frames should be dropped if the
outgoing queue was stopped.  This was not correctly implemented as we
were not checking the right queue.  Furthermore, we were dropping frames
that had arrived to their destination if that queue was stopped.

Subject: [PATCH 0956/1958] mac80211: don't initiate path discovery when
 forwarding frame with unknown DA

We used to initiate a path discovery when receiving a frame for which
there is no forwarding information. To cut down on PREQ spam, just send
a (gated) PERR in response.

Also separate path discovery logic from nexthop querying. This patch
means we no longer queue frames when forwarding, so kill the PERR TX
stuff in discard_frame().

Subject: [PATCH 0958/1958] mac80211: remove tracing config symbol

There's little point in this config symbol, if
tracing is disabled the overhead is negligible
and if you think it's too bad you can always
turn off tracing completely.

Also remove the part where we don't have sparse
check the tracing code -- it seems that it can
now deal with it (or the code changed).

Subject: [PATCH 0959/1958] ath5k: Switch from read-and-clear to write-to-clear
 method when handling PISR/SISR registers

Since card has 12 tx queues and we want to keep track of the interrupts
per queue we can't fit all these interrupt bits on a single register.
So we have 5 registers, the primary interrupt status register (PISR) and
the 4 secondary interupt status registers (SISRs).

In order to be able to read them all at once (atomic operation) Atheros
introduced the Read-And-Clear registers to make things easier. So when
reading RAC_PISR register, hw does a read on PISR and all SISRs, returns
the value of PISR, copies all SISR values to their shadow copies (RAC_SISRx)
and clears PISR and SISRs. This saves us from reading PISR/SISRs in a sequence.

So far we 've used this approach and MadWiFi/Windows driver etc also used it
for years.

It turns out this operation is not atomic after all (at least not on all cards)
That means it's possible to loose some interrupts because they came after the
copy step and hw cleared them on the clean step !

That's probably the reason we got missed beacons, got stuck queues etc and
couldn't figure out what was going on.

With this patch we switch from RaC operation to an alternative method (that
makes more sense IMHO anyway, I just chose to be on the safe side so far).
Instead of reading RAC registers, we read the normal PISR/SISR registers and
clear any bits we got by writing them back on the register. This will clear only
the bits we got on our read step and leave any new bits unaffected (at least
that's what docs say). So if any new interrupts come up we won't miss it.

I've tested this with an AR5213 and an AR2425 and it seems O.K.

Many thanks to Adrian Chadd for debuging this and reviewing the patch !

v2: Make sure we don't clear PISR bits that map to SISR generated interrupts
(added a comment on the code for this)

Subject: [PATCH 0962/1958] ath5k: Calibration re-work

Noise floor calibration does not interfere with traffic and should run more
often as part of our "short calibration". The full calibration is not the
noise floor calibration but the AGC + Gain_F (on RF5111 and RF5112) calibration
and should run less often because it does interfere with traffic.

So

Short calibration -> I/Q & NF Calibration
Long calibration -> Short + AGC + Gain_F

This patch was for some time on my pub/ dir on www.kernel.org and has been tested
by a few people and me. I think it's O.K. to go in.

I also changed ah_calibration to ah_iq_cal_needed to make more sense.

v2 Use a workqueue instead of a tasklet for calibration

From c47faa364cfb249d5d7670fb7293a6f9acd8aa9e Mon Sep 17 00:00:00 2001
From: Nick Kossifidis <mickflemm@gmail.com>
Date: Fri, 25 Nov 2011 20:40:25 +0200
Subject: [PATCH 0964/1958] ath5k: Cleanups v2 + add kerneldoc on all hw
 functions

No functional changes

Add kernel doc for all ath5k_hw_* functions and strcucts. Also do some cleanup,
rename ath5k_hw_init_beacon to ath5k_hw_init_beacon_timers, remove an unused
variable from ath5k_hw_pcu_init and a few obsolete macros, mostly related to XR.

+ * for 5GHz). Antenna 1 (MAIN) should be omnidirectional, 2 (AUX)
+ * omnidirectional or sectorial and antennas 3-14 sectorial (or directional).
+ *
+ * We can have a single antenna for RX and multiple antennas for TX.

+ * (all are bits of STA_ID1 register):
+ *
+ * AR5K_STA_ID1_DEFAULT_ANTENNA -> When 0 is set as the TX antenna on TX
+ * control descriptor, use the default antenna to transmit or else use the last
+ * antenna on which we received an ACK.

+ * AR5K_STA_ID1_RTS_DEF_ANTENNA -> Use default antenna for RTS or else use the
+ * one on the TX descriptor.
+ *
+ * AR5K_STA_ID1_SELFGEN_DEF_ANT -> Use default antenna for self generated frames
+ * (ACKs etc), or else use current antenna (the one we just used for TX).
+ *
+ * Using the above we support the following scenarios:
+ *
+ * AR5K_ANTMODE_DEFAULT -> Hw handles antenna diversity etc automatically
+ *
+ * AR5K_ANTMODE_FIXED_A	-> Only antenna A (MAIN) is present

Subject: [PATCH 0966/1958] ath5k: Add a module parameter to disable hw rf kill
 switch

Add a module parameter to disable hw rf kill switch (GPIO interrupt) because
in some cases when the card doesn't come with the laptop, EEPROM configuration
doesn't match laptop's configuration and rf kill interrupt always fires up and
disables hw. I thought of moving this to debugfs and make it per-card but
this way it's easier for users and distros to handle.

MRR support and 2GHz radio override belong in ah_capabilities and we
should use them (e.g. so far  we used to set mrr descriptor without
checking if MRR support is enabled + we checked for MRR support 2
times, one by trying to set up an MRR descriptor and another one based
on MAC version).

Subject: [PATCH 0969/1958] ath5k: Renumber hw queue ids

According to documentation higher DCUs have higher priority and should
be used for beacons and CAB traffic. More specifically DCU 9 should be
used for beacons and DCU 8 for CAB traffic, I assumed DCU 7 should be
OK for UAPSD traffic.

Note that DCU 8 and 9 are special because they can only be mapped to a single
QCU each but since we use a 1:1 mapping between QCUs and DCUs anyway we don't
have to change much.

P.S. I also did a few related cleanups on qcu.c and ath5k.h

Subject: [PATCH 0972/1958] iwlagn: remove calibration knowledge

The init microcode knows very well which calibrations
are required and sends us results for those that are.
Consequently, we can just send all of those to the RT
uCode again.

The problem with having the driver know about this is
that it is a uCode feature, not a hardware feature so
the config is completely unsuitable.

The only thing we need to check is whether the device
needs crystal calibration or not, add a new parameter
to the configuration for that.

This makes new uCode work on 6000 series devices.

Subject: [PATCH 0973/1958] iwlagn: dynamically allocate & reflect calibration
 data

This makes handling the calibration data more generic
and no longer requires updating IWL_CALIB_MAX when a
new uCode comes with more calibration packets. Since
we just copy the data back, there's also no need for
understanding which calibration we received -- we can
just reflect it back to the runtime uCode.

Now sk_route_caps is u64, its dangerous to use an integer to store
result of an AND operator. It wont work if NETIF_F_SG is moved on the
upper part of u64.

Subject: [PATCH 0988/1958] net: introduce skb_flow_dissect()

We use at least two flow dissectors in network stack, with known
limitations and code duplication.

Introduce skb_flow_dissect() to factorize this, highly inspired from
existing dissector from __skb_get_rxhash()

Note : We extensively use skb_header_pointer(), this permits us to not
touch skb at all.

Subject: [PATCH 0990/1958] cls_flow: use skb_flow_dissect()

Instead of using a custom flow dissector, use skb_flow_dissect() and
benefit from tunnelling support.

This lack of tunnelling support was mentioned by Dan Siemon.

Subject: [PATCH 0991/1958] sch_sfb: use skb_flow_dissect()

Current SFB double hashing is not fulfilling SFB theory, if two flows
share same rxhash value.

Using skb_flow_dissect() permits to really have better hash dispersion,
and get tunnelling support as well.

Double hashing point was mentioned by Florian Westphal

Subject: [PATCH 0992/1958] tg3: Fix TSO CAP for 5704 devs w / ASF enabled

On the earliest TSO capable devices, TSO was accomplished through
firmware.  The TSO cannot coexist with ASF management firmware though.
The tg3 driver determines whether or not ASF is enabled by calling
tg3_get_eeprom_hw_cfg(), which checks a particular bit of NIC memory.
Commit dabc5c670d3f86d15ee4f42ab38ec5bd2682487d, entitled "tg3: Move
TSO_CAPABLE assignment", accidentally moved the code that determines
TSO capabilities earlier than the call to tg3_get_eeprom_hw_cfg().  As a
consequence, the driver was attempting to determine TSO capabilities
before it had all the data it needed to make the decision.

This patch fixes the problem by revisiting and reevaluating the decision
after tg3_get_eeprom_hw_cfg() is called.

Subject: [PATCH 0993/1958] tg3: Scale back code that modifies MRRS

Tg3 normally gets a performance boost by increasing the PCI Maximum Read
Request Size (MRRS) to 4k.  Unfortunately, this is causing some problems
on particular hardware platforms.  This patch removes all code that
modifies the MRRS except for one case.

As part of a solution to fix an internal FIFO problem on the 5719, the
driver artificially capped the MRRS to 2k for the entire 5719, and later
5720, ASIC revs.  This was overly aggressive and only really needed to
be done for the 5719 A0.  In the spirit of the rest of this patch, the
driver will only reprogram the MRRS for this device if the value exceeds
the 2k cap.

Subject: [PATCH 0997/1958] NET: AX.25: Check ioctl arguments to avoid
 overflows further down the road.

Very large, nonsenical arguments or use in very extreme conditions could
result in integer overflows.  Check ioctls arguments to avoid such
overflows and return -EINVAL for too large arguments.

To allow the use of AX.25 for even the most extreme setup (think packet
radio to the Phase 5E mars probe) we make no further attempt to clamp the
argument range.

Originally reported by Fan Long <longfancn@gmail.com> and a first patch
was sent by Xi Wang <xi.wang@gmail.com>.

Subject: [PATCH 0998/1958] NET: NETROM: When adding a route verify length of
 mnemonic string.

struct nr_route_struct's mnemonic permits a string of up to 7 bytes to be
used.  If userland passes a not zero terminated string to the kernel adding
a node to the routing table might result in the kernel attempting to read
copy a too long string.

Mnemonic is part of the NET/ROM routing protocol; NET/ROM routing table
updates only broadcast 6 bytes.  The 7th byte in the mnemonic array exists
only as a \0 termination character for the kernel code's convenience.

Fixed by rejecting mnemonic strings that have no terminating \0 in the first
7 characters.  Do this test only NETROM_NODE to avoid breaking NETROM_NEIGH
where userland might passing an uninitialized mnemonic field.

Initial patch by Dan Carpenter <dan.carpenter@oracle.com>.

Subject: [PATCH 0999/1958] NET: NETROM: Cleanup argument SIOCADDRT ioctl
 argument checking.

nr_route.ndigis is unsigned int so the nr_route.ndigis < 0 expression is
never true and can be dropped.  Doing the nr_ax25_dev_get call later
allows the nr_route.ndigis test to bail out without having to dev_put.

From db62f684deeb291ab2533b99843d5df9a36b1f19 Mon Sep 17 00:00:00 2001
From: Axel Lin <axel.lin@gmail.com>
Date: Sun, 27 Nov 2011 16:44:17 +0000
Subject: [PATCH 1002/1958] net/ethernet: convert drivers/net/ethernet/* to use
 module_platform_driver()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch converts the drivers in drivers/net/ethernet/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

Since jump_label_{inc|dec} must be called from process context only,
we must defer jump_label_dec() if net_disable_timestamp() is called
from interrupt context.

Subject: [PATCH 1007/1958] tcp: do not scale TSO segment size with reordering
 degree

Since 2005 (c1b4a7e69576d65efc31a8cea0714173c2841244)
tcp_tso_should_defer has been using tcp_max_burst() as a target limit
for deciding how large to make outgoing TSO packets when not using
sysctl_tcp_tso_win_divisor. But since 2008
(dd9e0dda66ba38a2ddd1405ac279894260dc5c36) tcp_max_burst() returns the
reordering degree. We should not have tcp_tso_should_defer attempt to
build larger segments just because there is more reordering. This
commit splits the notion of deferral size used in TSO from the notion
of burst size used in cwnd moderation, and returns the TSO deferral
limit to its original value.

Subject: [PATCH 1010/1958] dql: Dynamic queue limits

Implementation of dynamic queue limits (dql).  This is a libary which
allows a queue limit to be dynamically managed.  The goal of dql is
to set the queue limit, number of objects to the queue, to be minimized
without allowing the queue to be starved.

dql would be used with a queue which has these properties:

1) Objects are queued up to some limit which can be expressed as a
   count of objects.
2) Periodically a completion process executes which retires consumed
   objects.
3) Starvation occurs when limit has been reached, all queued data has
   actually been consumed but completion processing has not yet run,
   so queuing new data is blocked.
4) Minimizing the amount of queued data is desirable.

A canonical example of such a queue would be a NIC HW transmit queue.

The queue limit is dynamic, it will increase or decrease over time
depending on the workload.  The queue limit is recalculated each time
completion processing is done.  Increases occur when the queue is
starved and can exponentially increase over successive intervals.
Decreases occur when more data is being maintained in the queue than
needed to prevent starvation.  The number of extra objects, or "slack",
is measured over successive intervals, and to avoid hysteresis the
limit is only reduced by the miminum slack seen over a configurable
time period.

dql API provides routines to manage the queue:
- dql_init is called to intialize the dql structure
- dql_reset is called to reset dynamic values
- dql_queued called when objects are being enqueued
- dql_avail returns availability in the queue
- dql_completed is called when objects have be consumed in the queue

Configuration consists of:
- max_limit, maximum limit
- min_limit, minimum limit
- slack_hold_time, time to measure instances of slack before reducing
  queue limit

+ * Dynamic queue limits (dql) - Definitions
+ *
+ * Copyright (c) 2011, Tom Herbert <therbert@google.com>
+ *
+ * This header file contains the definitions for dynamic queue limits (dql).
+ * dql would be used in conjunction with a producer/consumer type queue
+ * (possibly a HW queue).  Such a queue would have these general properties:
+ *
+ *   1) Objects are queued up to some limit specified as number of objects.
+ *   2) Periodically a completion process executes which retires consumed
+ *      objects.
+ *   3) Starvation occurs when limit has been reached, all queued data has
+ *      actually been consumed, but completion processing has not yet run
+ *      so queuing new data is blocked.
+ *   4) Minimizing the amount of queued data is desirable.
+ *
+ * The goal of dql is to calculate the limit as the minimum number of objects
+ * needed to prevent starvation.
+ *
+ * The primary functions of dql are:
+ *    dql_queued - called when objects are enqueued to record number of objects
+ *    dql_avail - returns how many objects are available to be queued based
+ *      on the object limit and how many objects are already enqueued
+ *    dql_completed - called at completion time to indicate how many objects
+ *      were retired from the queue
+ *
+ * The dql implementation does not implement any locking for the dql data
+ * structures, the higher layer should provide this.  dql_queued should
+ * be serialized to prevent concurrent execution of the function; this
+ * is also true for  dql_completed.  However, dql_queued and dlq_completed  can
+ * be executed concurrently (i.e. they can be protected by different locks).

Subject: [PATCH 1011/1958] net: Add queue state xoff flag for stack

Create separate queue state flags so that either the stack or drivers
can turn on XOFF.  Added a set of functions used in the stack to determine
if a queue is really stopped (either by stack or driver)

Subject: [PATCH 1012/1958] net: Add netdev interfaces for recording sends/comp

Add interfaces for drivers to call for recording number of packets and
bytes at send time and transmit completion.  Also, added a function to
"reset" a queue.  These will be used by Byte Queue Limits.

Subject: [PATCH 1013/1958] xps: Add xps_queue_release function

This patch moves the xps specific parts in netdev_queue_release into
its own function which netdev_queue_release can call.  This allows
netdev_queue_release to be more generic (for adding new attributes
to tx queues).

Subject: [PATCH 1014/1958] bql: Byte queue limits

Networking stack support for byte queue limits, uses dynamic queue
limits library.  Byte queue limits are maintained per transmit queue,
and a dql structure has been added to netdev_queue structure for this
purpose.

Configuration of bql is in the tx-<n> sysfs directory for the queue
under the byte_queue_limits directory.  Configuration includes:
limit_min, bql minimum limit
limit_max, bql maximum limit
hold_time, bql slack hold time

Also under the directory are:
limit, current byte limit
inflight, current number of bytes on the queue

( CC trimmed )

Thanks David !

Here is a small patch to use one 64bit load/store on x86_64 instead of
two 32bit load/stores.

[PATCH net-next] flow_dissector: use a 64bit load/store

gcc compiler is smart enough to use a single load/store if we
memcpy(dptr, sptr, 8) on x86_64, regardless of
CONFIG_CC_OPTIMIZE_FOR_SIZE

In IP header, daddr immediately follows saddr, this wont change in the
future. We only need to make sure our flow_keys (src,dst) fields wont
break the rule.

Subject: [PATCH 1021/1958] tcp: avoid frag allocation for small frames

tcp_sendmsg() uses select_size() helper to choose skb head size when a
new skb must be allocated.

If GSO is enabled for the socket, current strategy is to force all
payload data to be outside of headroom, in PAGE fragments.

This strategy is not welcome for small packets, wasting memory.

Experiments show that best results are obtained when using 2048 bytes
for skb head (This includes the skb overhead and various headers)

This patch provides better len/truesize ratios for packets sent to
loopback device, and reduce memory needs for in-flight loopback packets,
particularly on arches with big pages.

If a sender sends many 1-byte packets to an unresponsive application,
receiver rmem_alloc will grow faster and will stop queuing these packets
sooner, or will collapse its receive queue to free excess memory.

netperf -t TCP_RR results are improved by ~4 %, and many workloads are
improved as well (tbench, mysql...)

Commit 7dc00c82 added a 'notify' parameter for vif_delete() to
distinguish whether to unregister the device.

When notify=1 means we does not need to unregister the device,
so calling unregister_netdevice_many is useless.

This driver is currently not supported on x86_64 systems because the

limitation, the driver is converted to a platform driver, similar to
the serial 8250 driver.

Subject: [PATCH 1028/1958] net/smsc911x: Add regulator support

Add some basic regulator support for the power pins, as needed
by the ST-Ericsson Snowball platform that powers up the SMSC911
chip using an external regulator.

Platforms that use regulators and the smsc911x and have no defined
regulator for the smsc911x and claim complete regulator
constraints with no dummy regulators will need to provide it, for
example using a fixed voltage regulator. It appears that this may
affect (apart from Ux500 Snowball) possibly these archs/machines
that from some grep:s appear to define both CONFIG_SMSC911X and
CONFIG_REGULATOR:

- ARM Freescale mx3 and OMAP 2 plus, Raumfeld machines
- Blackfin
- Super-H

+
+/*
+ * The CC770 is a CAN controller from Bosch, which is 100% compatible
+ * with the AN82527 from Intel, but with "bugs" being fixed and some
+ * additional functionality, mainly:
+ *
+ * 1. RX and TX error counters are readable.
+ * 2. Support of silent (listen-only) mode.
+ * 3. Message object 15 can receive all types of frames, also RTR and EFF.
+ *
+ * Details are available from Bosch's "CC770_Product_Info_2007-01.pdf",
+ * which explains in detail the compatibility between the CC770 and the
+ * 82527. This driver use the additional functionality 3. on real CC770
+ * devices. Unfortunately, the CC770 does still not store the message
+ * identifier of received remote transmission request frames and
+ * therefore it's set to 0.
+ *
+ * The message objects 1..14 can be used for TX and RX while the message
+ * objects 15 is optimized for RX. It has a shadow register for reliable
+ * data receiption under heavy bus load. Therefore it makes sense to use
+ * this message object for the needed use case. The frame type (EFF/SFF)
+ * for the message object 15 can be defined via kernel module parameter
+ * "msgobj15_eff". If not equal 0, it will receive 29-bit EFF frames,
+ * otherwise 11 bit SFF messages.

Subject: [PATCH 1030/1958] can: cc770: legacy CC770 ISA bus driver

This patch adds support for legacy Bosch CC770 and Intel AN82527 CAN
controllers on the ISA or PC-104 bus. The I/O port or memory address
and the IRQ number must be specified via module parameters:

  insmod cc770_isa.ko port=0x310,0x380 irq=7,11

for ISA devices using I/O ports or:

  insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11

for memory mapped ISA devices.

Indirect access via address and data port is supported as well:

  insmod cc770_isa.ko port=0x310,0x380 indirect=1 irq=7,11

Furthermore, the following mode parameter can be defined:

  clk: External oscillator clock frequency (default=16000000 [16 MHz])
  cir: CPU interface register (default=0x40 [CPU_DSC])
  ocr, Bus configuration register (default=0x00)
  cor, Clockout register (default=0x00)

Note: for clk, cir, bcr and cor, the first argument re-defines the
default for all other devices, e.g.:

  insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000

is equivalent to

  insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000,24000000

Subject: [PATCH 1031/1958] bnx2x: handle iSCSI SD mode

in iSCSI SD mode to bnx2x device assigned single mac address
which is supposted to be iscsi mac. If this mode is recognized
bnx2x will disable LRO, decrease number of queues to 1 and rx ring
size to the minumum allowed by FW, this in order minimize memory use.
It will tranfer mac for iscsi usage and zero primary mac of the netdev.

This patch converts the drivers in net/rfkill/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

Subject: [PATCH 1038/1958] mac80211: revert on-channel work optimisations

The on-channel work optimisations have caused a
number of issues, and the code is unfortunately
very complex and almost impossible to follow.
Instead of attempting to put in more workarounds
let's just remove those optimisations, we can
work on them again later, after we change the
whole auth/assoc design.

This should fix rate_control_send_low() warnings,

From ed1e0ad8816389ceefa2d94a9a3d3520088e410f Mon Sep 17 00:00:00 2001
From: Joe Perches <joe@perches.com>
Date: Tue, 29 Nov 2011 11:37:32 -0800
Subject: [PATCH 1043/1958] nfc: Use standard logging styles

Using the normal logging styles is preferred over
subsystem specific styles when the subsystem does
not take a specific struct.

Convert nfc_<level> specific messages to pr_<level>
Add newlines to uses.

From 20c239c1390bd6f3bb389fe1a7e8307f29f52563 Mon Sep 17 00:00:00 2001
From: Joe Perches <joe@perches.com>
Date: Tue, 29 Nov 2011 11:37:33 -0800
Subject: [PATCH 1044/1958] nfc: Convert nfc_dbg to pr_debug

Using the standard debugging mechanisms is better than
subsystem specific ones when the subsystem doesn't use
a specific struct.

Coalesce long formats.

WLAN communicates with BT for its calibration by sending WLAN_CAL_REQ,
waits for BT_CAL_GRANT. This is done with the help of GPM messages.
also WLAN_CAL_DONE messages is sent once WLAN calibration is done.

Subject: [PATCH 1061/1958] ath9k_hw: Add MCI related changes in chip reset

here we check for BT state and if BT calibration has started,
give 25ms for BT Calibration to finish. we also take care of 2G/5G
switch and LNA transfer incase WLAN is operating in 5G. in case the BT
state is awake when we do WLAN calibration re-calibrate and we reset
the message exchange between WLAN and BT. BT is given preference when
simultaneous CAL request happens. calibration for WLAN/BT is done
assuming that the other co-existing module is in awake state, if not
we continue to do calibration while if the other module's state changes
we need to do restart the calibration handshake

the default tx/rx chainmask for AR9462 is 0x3.
this patch helps to assign 0x3 rather than 0x7 for
AR9462 with the help of fix_chainmask module if something
goes wrong in reading tx/rx chain mask from OTP/EEPROM
card(though its very unlikely)

-/*
- * The CC770 is a CAN controller from Bosch, which is 100% compatible
- * with the AN82527 from Intel, but with "bugs" being fixed and some
- * additional functionality, mainly:
- *
- * 1. RX and TX error counters are readable.
- * 2. Support of silent (listen-only) mode.
- * 3. Message object 15 can receive all types of frames, also RTR and EFF.
- *
- * Details are available from Bosch's "CC770_Product_Info_2007-01.pdf",
- * which explains in detail the compatibility between the CC770 and the
- * 82527. This driver use the additional functionality 3. on real CC770
- * devices. Unfortunately, the CC770 does still not store the message
- * identifier of received remote transmission request frames and
- * therefore it's set to 0.
- *
- * The message objects 1..14 can be used for TX and RX while the message
- * objects 15 is optimized for RX. It has a shadow register for reliable
- * data receiption under heavy bus load. Therefore it makes sense to use
- * this message object for the needed use case. The frame type (EFF/SFF)
- * for the message object 15 can be defined via kernel module parameter
- * "msgobj15_eff". If not equal 0, it will receive 29-bit EFF frames,
- * otherwise 11 bit SFF messages.

Subject: [PATCH 1070/1958] tcp: inherit listener congestion control for
 passive cnx

Rick Jones reported that TCP_CONGESTION sockopt performed on a listener
was ignored for its children sockets : right after accept() the
congestion control for new socket is the system default one.

This seems an oversight of the initial design (quoted from Stephen)

Based on prior investigation and patch from Rick.

Subject: [PATCH 1074/1958] neigh: Get rid of neigh_table->kmem_cachep

We are going to alloc for device specific private areas for
neighbour entries, and in order to do that we have to move
away from the fixed allocation size enforced by using
neigh_table->kmem_cachep

As a nice side effect we can now use kfree_rcu().

From 7bc0f28c7a0cd19f40e5a6e4d0a117db9a4e4cd5 Mon Sep 17 00:00:00 2001
From: Hagen Paul Pfeifer <hagen@jauu.net>

Subject: [PATCH 1082/1958] netem: rate extension

Currently netem is not in the ability to emulate channel bandwidth. Only static
delay (and optional random jitter) can be configured.

To emulate the channel rate the token bucket filter (sch_tbf) can be used.  But
TBF has some major emulation flaws. The buffer (token bucket depth/rate) cannot
be 0. Also the idea behind TBF is that the credit (token in buckets) fills if
no packet is transmitted. So that there is always a "positive" credit for new
packets. In real life this behavior contradicts the law of nature where
nothing can travel faster as speed of light. E.g.: on an emulated 1000 byte/s
link a small IPv4/TCP SYN packet with ~50 byte require ~0.05 seconds - not 0
seconds.

Netem is an excellent place to implement a rate limiting feature: static
delay is already implemented, tfifo already has time information and the
user can skip TBF configuration completely.

This patch implement rate feature which can be configured via tc. e.g:

	tc qdisc add dev eth0 root netem rate 10kbit

To emulate a link of 5000byte/s and add an additional static delay of 10ms:

	tc qdisc add dev eth0 root netem delay 10ms rate 5KBps

Note: similar to TBF the rate extension is bounded to the kernel timing
system. Depending on the architecture timer granularity, higher rates (e.g.
10mbit/s and higher) tend to transmission bursts. Also note: further queues
living in network adaptors; see ethtool(8).

Subject: [PATCH 1093/1958] wl12xx: configure probe-resp template according to
 notification

When operating in AP-mode, replace our probe-response template when a
notification is recieved from mac80211. We preserve the "legacy" way of
configuring a probe-response according to beacon for IBSS mode and for
versions of hostapd that do not support this feature.

Subject: [PATCH 1096/1958] wl12xx: avoid bail out when probe-resp is not set
 by mac80211

During reconfig we can get the BSS_CHANGED_AP_PROBE_RESP indication
even if a probe-resp has not been set in the first place. Therefore
ignore the error when not getting a probe-resp from mac80211. Resort to
the legacy probe-resp in this case.

Also take this opportunity to add a vif argument to the set_probe_resp
function.

Subject: [PATCH 1098/1958] wl12xx: leave IV calculation to HW for CCMP

Use an appropriate mac80211 flags in CCMP keys to indicate we are
calculating the CCMP IV in HW, but require room for the IV to be reserved
in the skb. The space is reserved by mac80211.

depends on "mac80211: support adding IV-room in the skb for CCMP keys".

Subject: [PATCH 1099/1958] wl12xx: don't explicitly check for unjoined ibss

After the ibss carrier issue was fixed, we can revert
the following patch:

commit 48309fd477ef867babb6819f67fe082c133a5fa9
Author: Shahar Lev <shahar@wizery.com>
Date:   Fri Oct 7 18:17:25 2011 +0200

    wl12xx: remove warning message during IBSS Tx

    mac80211 sets the carrier on an IBSS interface even when no network is
    joined. Ignore garbage frames transmitted on a disconnected IBSS
    interface without printing warnings.

Subject: [PATCH 1103/1958] icplus: mdio_write(), remove unnecessary for loop

At this point the variable j is always set to 7 and the code within
the loop has to run only once anyway.

As suggested by David Miller:
"You can simply this even further since p[7] is what is used here,
and this means len is one, the inner loop therefore executes only
once, and the p[7].field value is not used (it's zero in the table)
and the write to it is completely thrown away."

+ * 2. Support of silent (listen-only) mode.

+ * therefore it's set to 0.
+ *
+ * The message objects 1..14 can be used for TX and RX while the message

From edd2c26ffb7742bf0d3bd324694d220281844a01 Mon Sep 17 00:00:00 2001
From: Wolfgang Grandegger <wg@grandegger.com>
Date: Wed, 30 Nov 2011 23:41:19 +0000
Subject: [PATCH 1105/1958] can: cc770: add legacy ISA bus driver for the CC770
 and AN82527

This patch adds support for legacy Bosch CC770 and Intel AN82527 CAN
controllers on the ISA or PC-104 bus. The I/O port or memory address
and the IRQ number must be specified via module parameters:

  insmod cc770_isa.ko port=0x310,0x380 irq=7,11

for ISA devices using I/O ports or:

  insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11

for memory mapped ISA devices.

Indirect access via address and data port is supported as well:

  insmod cc770_isa.ko port=0x310,0x380 indirect=1 irq=7,11

Furthermore, the following mode parameter can be defined:

  clk: External oscillator clock frequency (default=16000000 [16 MHz])
  cir: CPU interface register (default=0x40 [DSC])
  bcr: Bus configuration register (default=0x40 [CBY])
  cor: Clockout register (default=0x00)

Note: for clk, cir, bcr and cor, the first argument re-defines the
default for all other devices, e.g.:

  insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000

is equivalent to

  insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000,24000000

Subject: [PATCH 1106/1958] can: cc770: add platform bus driver for the CC770
 and AN82527

This driver works with both, static platform data and device tree
bindings. It has been tested on a TQM855L board with two AN82527
CAN controllers on the local bus.

+Memory mapped Bosch CC770 and Intel AN82527 CAN controller
+
+Note: The CC770 is a CAN controller from Bosch, which is 100%
+compatible with the old AN82527 from Intel, but with "bugs" being fixed.
+
+Required properties:
+
+- compatible : should be "bosch,cc770" for the CC770 and "intc,82527"
+	for the AN82527.
+
+- reg : should specify the chip select, address offset and size required
+	to map the registers of the controller. The size is usually 0x80.
+
+- interrupts : property with a value describing the interrupt source
+	(number and sensitivity) required for the controller.
+
+Optional properties:
+
+- bosch,external-clock-frequency : frequency of the external oscillator
+	clock in Hz. Note that the internal clock frequency used by the
+	controller is half of that value. If not specified, a default
+	value of 16000000 (16 MHz) is used.
+
+- bosch,clock-out-frequency : slock frequency in Hz on the CLKOUT pin.
+	If not specified or if the specified value is 0, the CLKOUT pin
+	will be disabled.
+
+- bosch,slew-rate : slew rate of the CLKOUT signal. If not specified,
+	a resonable value will be calculated.
+
+- bosch,disconnect-rx0-input : see data sheet.
+
+- bosch,disconnect-rx1-input : see data sheet.
+
+- bosch,disconnect-tx1-output : see data sheet.
+
+- bosch,polarity-dominant : see data sheet.
+
+- bosch,divide-memory-clock : see data sheet.
+
+- bosch,iso-low-speed-mux : see data sheet.
+
+For further information, please have a look to the CC770 or AN82527.
+
+Examples:
+
+can@3,100 {
+	compatible = "bosch,cc770";
+	reg = <3 0x100 0x80>;
+	interrupts = <2 0>;
+	interrupt-parent = <&mpic>;
+	bosch,external-clock-frequency = <16000000>;

 dccp_v4_route_skb().

This also works around a bogus gcc warning generated by an
upcoming patch from Eric Dumazet that rearranges the layout
of struct flowi4.

Subject: [PATCH 1109/1958] ipv4: use a 64bit load/store in output path

gcc compiler is smart enough to use a single load/store if we
memcpy(dptr, sptr, 8) on x86_64, regardless of
CONFIG_CC_OPTIMIZE_FOR_SIZE

In IP header, daddr immediately follows saddr, this wont change in the
future. We only need to make sure our flowi4 (saddr,daddr) fields wont
break the rule.

Subject: [PATCH 1111/1958] dccp: Fix compile warning in probe code.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Commit 1386be55e32a3c5d8ef4a2b243c530a7b664c02c ("dccp: fix
auto-loading of dccp(_probe)") fixed a bug but created a new
compiler warning:

net/dccp/probe.c: In function ‘dccpprobe_init’:
net/dccp/probe.c:166:2: warning: the omitted middle operand in ?: will always be ‘true’, suggest explicit middle operand [-Wparentheses]

try_then_request_module() is built for situations where the
"existence" test is some lookup function that returns a non-NULL
object on success, and with a reference count of some kind held.

Here we're looking for a success return of zero from the jprobe
registry.

Instead of fighting the way try_then_request_module() works, simply
open code what we want to happen in a local helper function.

Subject: [PATCH 1115/1958] Bluetooth: Add dev_flags to struct hci_dev

This patch adds the dev_flags field to struct hci_dev. This new
flags variable should be used to define flags related to BR/EDR
and/or LE controller itself. It should be used to define flags
which represents states from the controller. The dev_flags is
cleared in case the controller sends a Reset Command Complete
Event to the host.

Also, this patch adds the HCI_LE_SCAN flag which was created to
track if the controller is performing LE scan or not. The flag
is set/cleared when the controller starts/stops scanning.

This is an initial effort to stop using hdev->flags to define
internal flags since it is exported to userspace by an ioctl.

Subject: [PATCH 1119/1958] iwlwifi: add tm commands for sram reading by dumpit

Create new testmode commands and attributes to suppot
sram data reading. Because the amount of sram data
may exceed single skb packet size. Using the nl80211
dump it funtion to deliver sram data to userspace.

- IWL_TM_CMD_APP2DEV_READ_SRAM
- IWL_TM_CMD_APP2DEV_DUMP_SRAM
- IWL_TM_ATTR_SRAM_ADDR
- IWL_TM_ATTR_SRAM_SIZE
- IWL_TM_ATTR_SRAM_DUMP

Subject: [PATCH 1123/1958] iwlagn: fix HW crypto for TX-only keys

Group keys in IBSS or AP mode are not programmed
into the device since we give the key to it with
every TX packet. However, we do need mac80211 to
create the MMIC & PN in all cases. Move the code
around to set the key flags all the time. We set
them even when the key is removed again but that
is obviously harmless.

Subject: [PATCH 1131/1958] iwlwifi: replace iwl_priv reference with iwl_trans
 for ucode.

Replace the references to the iwl_priv structure with the iwl_trans
structure as the priv structure is never referenced other than to
access the trans structure.  Rename from iwlagn to iwl.

Open vSwitch uses Generic Netlink interface for communication
between userspace and kernel module. genl_notify() is used
for sending notification back to userspace.

genl_notify() is analogous to rtnl_notify() but uses genl_sock
instead of rtnl.

From 75f2811c6460ccc59d83c66059943ce9c9f81a18 Mon Sep 17 00:00:00 2001
From: Jesse Gross <jesse@nicira.com>

Subject: [PATCH 1143/1958] ipv6: Add fragment reporting to ipv6_skip_exthdr().

While parsing through IPv6 extension headers, fragment headers are
skipped making them invisible to the caller.  This reports the
fragment offset of the last header in order to make it possible to
determine whether the packet is fragmented and, if so whether it is
a first or last fragment.

From ccb1352e76cff0524e7ccb2074826a092dd13016 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1144/1958] net: Add Open vSwitch kernel components.

Open vSwitch is a multilayer Ethernet switch targeted at virtualized
environments.  In addition to supporting a variety of features
expected in a traditional hardware switch, it enables fine-grained
programmatic extension and flow-based control of the network.
This control is useful in a wide variety of applications but is
particularly important in multi-server virtualization deployments,
which are often characterized by highly dynamic endpoints and the need
to maintain logical abstractions for multiple tenants.

The Open vSwitch datapath provides an in-kernel fast path for packet
forwarding.  It is complemented by a userspace daemon, ovs-vswitchd,
which is able to accept configuration from a variety of sources and
translate it into packet processing rules.

See http://openvswitch.org for more information and userspace
utilities.

+Open vSwitch datapath developer documentation
+=============================================
+
+The Open vSwitch kernel module allows flexible userspace control over
+flow-level packet processing on selected network devices.  It can be
+used to implement a plain Ethernet switch, network device bonding,
+VLAN processing, network access control, flow-based network control,
+and so on.
+
+The kernel module implements multiple "datapaths" (analogous to
+bridges), each of which can have multiple "vports" (analogous to ports
+within a bridge).  Each datapath also has associated with it a "flow
+table" that userspace populates with "flows" that map from keys based
+on packet headers and metadata to sets of actions.  The most common
+action forwards the packet to another vport; other actions are also
+implemented.
+
+When a packet arrives on a vport, the kernel module processes it by
+extracting its flow key and looking it up in the flow table.  If there
+is a matching flow, it executes the associated actions.  If there is
+no match, it queues the packet to userspace for processing (as part of
+its processing, userspace will likely set up a flow to handle further
+packets of the same type entirely in-kernel).
+
+
+Flow key compatibility
+----------------------
+
+Network protocols evolve over time.  New protocols become important
+and existing protocols lose their prominence.  For the Open vSwitch
+kernel module to remain relevant, it must be possible for newer
+versions to parse additional protocols as part of the flow key.  It
+might even be desirable, someday, to drop support for parsing
+protocols that have become obsolete.  Therefore, the Netlink interface
+to Open vSwitch is designed to allow carefully written userspace
+applications to work with any version of the flow key, past or future.
+
+To support this forward and backward compatibility, whenever the
+kernel module passes a packet to userspace, it also passes along the
+flow key that it parsed from the packet.  Userspace then extracts its
+own notion of a flow key from the packet and compares it against the
+kernel-provided version:
+
+    - If userspace's notion of the flow key for the packet matches the
+      kernel's, then nothing special is necessary.
+
+    - If the kernel's flow key includes more fields than the userspace
+      version of the flow key, for example if the kernel decoded IPv6
+      headers but userspace stopped at the Ethernet type (because it
+      does not understand IPv6), then again nothing special is
+      necessary.  Userspace can still set up a flow in the usual way,
+      as long as it uses the kernel-provided flow key to do it.
+
+    - If the userspace flow key includes more fields than the
+      kernel's, for example if userspace decoded an IPv6 header but
+      the kernel stopped at the Ethernet type, then userspace can
+      forward the packet manually, without setting up a flow in the
+      kernel.  This case is bad for performance because every packet
+      that the kernel considers part of the flow must go to userspace,
+      but the forwarding behavior is correct.  (If userspace can
+      determine that the values of the extra fields would not affect
+      forwarding behavior, then it could set up a flow anyway.)
+
+How flow keys evolve over time is important to making this work, so
+the following sections go into detail.
+
+
+Flow key format
+---------------
+
+A flow key is passed over a Netlink socket as a sequence of Netlink
+attributes.  Some attributes represent packet metadata, defined as any
+information about a packet that cannot be extracted from the packet
+itself, e.g. the vport on which the packet was received.  Most
+attributes, however, are extracted from headers within the packet,
+e.g. source and destination addresses from Ethernet, IP, or TCP
+headers.
+
+The <linux/openvswitch.h> header file defines the exact format of the
+flow key attributes.  For informal explanatory purposes here, we write
+them as comma-separated strings, with parentheses indicating arguments
+and nesting.  For example, the following could represent a flow key
+corresponding to a TCP packet that arrived on vport 1:
+
+    in_port(1), eth(src=e0:91:f5:21:d0:b2, dst=00:02:e3:0f:80:a4),
+    eth_type(0x0800), ipv4(src=172.16.0.20, dst=172.18.0.52, proto=17, tos=0,
+    frag=no), tcp(src=49163, dst=80)
+
+Often we ellipsize arguments not important to the discussion, e.g.:
+
+    in_port(1), eth(...), eth_type(0x0800), ipv4(...), tcp(...)
+
+
+Basic rule for evolving flow keys
+---------------------------------
+
+Some care is needed to really maintain forward and backward
+compatibility for applications that follow the rules listed under
+"Flow key compatibility" above.
+
+The basic rule is obvious:
+
+    ------------------------------------------------------------------
+    New network protocol support must only supplement existing flow
+    key attributes.  It must not change the meaning of already defined
+    flow key attributes.
+    ------------------------------------------------------------------
+
+This rule does have less-obvious consequences so it is worth working
+through a few examples.  Suppose, for example, that the kernel module
+did not already implement VLAN parsing.  Instead, it just interpreted
+the 802.1Q TPID (0x8100) as the Ethertype then stopped parsing the
+packet.  The flow key for any packet with an 802.1Q header would look
+essentially like this, ignoring metadata:
+
+    eth(...), eth_type(0x8100)
+
+Naively, to add VLAN support, it makes sense to add a new "vlan" flow
+key attribute to contain the VLAN tag, then continue to decode the
+encapsulated headers beyond the VLAN tag using the existing field
+definitions.  With this change, an TCP packet in VLAN 10 would have a
+flow key much like this:
+
+    eth(...), vlan(vid=10, pcp=0), eth_type(0x0800), ip(proto=6, ...), tcp(...)
+
+But this change would negatively affect a userspace application that
+has not been updated to understand the new "vlan" flow key attribute.
+The application could, following the flow compatibility rules above,
+ignore the "vlan" attribute that it does not understand and therefore
+assume that the flow contained IP packets.  This is a bad assumption
+(the flow only contains IP packets if one parses and skips over the
+802.1Q header) and it could cause the application's behavior to change
+across kernel versions even though it follows the compatibility rules.
+
+The solution is to use a set of nested attributes.  This is, for
+example, why 802.1Q support uses nested attributes.  A TCP packet in
+VLAN 10 is actually expressed as:
+
+    eth(...), eth_type(0x8100), vlan(vid=10, pcp=0), encap(eth_type(0x0800),
+    ip(proto=6, ...), tcp(...)))
+
+Notice how the "eth_type", "ip", and "tcp" flow key attributes are
+nested inside the "encap" attribute.  Thus, an application that does
+not understand the "vlan" key will not see either of those attributes
+and therefore will not misinterpret them.  (Also, the outer eth_type
+is still 0x8100, not changed to 0x0800.)
+
+Handling malformed packets
+--------------------------
+
+Don't drop packets in the kernel for malformed protocol headers, bad
+checksums, etc.  This would prevent userspace from implementing a
+simple Ethernet switch that forwards every packet.
+
+Instead, in such a case, include an attribute with "empty" content.
+It doesn't matter if the empty content could be valid protocol values,
+as long as those values are rarely seen in practice, because userspace
+can always forward all packets with those values to userspace and
+handle them individually.
+
+For example, consider a packet that contains an IP header that
+indicates protocol 6 for TCP, but which is truncated just after the IP
+header, so that the TCP header is missing.  The flow key for this
+packet would include a tcp attribute with all-zero src and dst, like
+this:
+
+    eth(...), eth_type(0x0800), ip(proto=6, ...), tcp(src=0, dst=0)
+
+As another example, consider a packet with an Ethernet type of 0x8100,
+indicating that a VLAN TCI should follow, but which is truncated just
+after the Ethernet type.  The flow key for this packet would include
+an all-zero-bits vlan and an empty encap attribute, like this:
+
+    eth(...), eth_type(0x8100), vlan(0), encap()
+
+Unlike a TCP packet with source and destination ports 0, an
+all-zero-bits VLAN TCI is not that rare, so the CFI bit (aka
+VLAN_TAG_PRESENT inside the kernel) is ordinarily set in a vlan
+attribute expressly to allow this situation to be distinguished.
+Thus, the flow key in this second example unambiguously indicates a
+missing or malformed VLAN TCI.
+
+Other rules
+-----------
+
+The other rules for flow keys are much less subtle:
+
+    - Duplicate attributes are not allowed at a given nesting level.
+
+    - Ordering of attributes is not significant.
+
+    - When the kernel sends a given flow key to userspace, it always
+      composes it the same way.  This allows userspace to hash and
+      compare entire flow keys that it may not be able to fully
+      interpret.

+	tristate "Open vSwitch"
+	---help---
+	  Open vSwitch is a multilayer Ethernet switch targeted at virtualized
+	  environments.  In addition to supporting a variety of features
+	  expected in a traditional hardware switch, it enables fine-grained
+	  programmatic extension and flow-based control of the network.  This
+	  control is useful in a wide variety of applications but is
+	  particularly important in multi-server virtualization deployments,
+	  which are often characterized by highly dynamic endpoints and the
+	  need to maintain logical abstractions for multiple tenants.
+
+	  The Open vSwitch datapath provides an in-kernel fast path for packet
+	  forwarding.  It is complemented by a userspace daemon, ovs-vswitchd,
+	  which is able to accept configuration from a variety of sources and
+	  translate it into packet processing rules.
+
+	  See http://openvswitch.org for more information and userspace
+	  utilities.
+
+	  To compile this code as a module, choose M here: the module will be
+	  called openvswitch.
+
+	  If unsure, say N.

From: "David S. Miller" <davem@davemloft.net>
Date: Sat, 3 Dec 2011 17:50:45 -0500
Subject: [PATCH 1145/1958] ipv6: Various cleanups in ip6_route.c

1) x == NULL --> !x
2) x != NULL --> x
3) if() --> if ()
4) while() --> while ()
5) (x & BIT) == 0 --> !(x & BIT)
6) (x&BIT) --> (x & BIT)
7) x=y --> x = y
8) (BIT1|BIT2) --> (BIT1 | BIT2)
9) if ((x & BIT)) --> if (x & BIT)
10) proper argument and struct member alignment

Subject: [PATCH 1146/1958] ipv6: Various cleanups in route.c

1) x == NULL --> !x
2) x != NULL --> x
3) (x&BIT) --> (x & BIT)
4) (BIT1|BIT2) --> (BIT1 | BIT2)
5) proper argument and struct member alignment

From 04a6f4417bfd17c3860e8fb37387cb78265ffe44 Mon Sep 17 00:00:00 2001

Date: Sat, 3 Dec 2011 18:29:30 -0500
Subject: [PATCH 1147/1958] ipv6: Kill ndisc_get_neigh() inline helper.

It's only used in net/ipv6/route.c and the NULL device check is
superfluous for all of the existing call sites.

Just expand the __ndisc_lookup_errno() call at each location.

Subject: [PATCH 1153/1958] tcp: take care of misalignments

We discovered that TCP stack could retransmit misaligned skbs if a
malicious peer acknowledged sub MSS frame. This currently can happen
only if output interface is non SG enabled : If SG is enabled, tcp
builds headless skbs (all payload is included in fragments), so the tcp
trimming process only removes parts of skb fragments, header stay
aligned.

Some arches cant handle misalignments, so force a head reallocation and
shrink headroom to MAX_TCP_HEADER.

Dont care about misaligments on x86 and PPC (or other arches setting
NET_IP_ALIGN to 0)

This patch introduces __pskb_copy() which can specify the headroom of
new head, and pskb_copy() becomes a wrapper on top of __pskb_copy()

Subject: [PATCH 1156/1958] netfilter: add ipv4 reverse path filter match

This tries to do the same thing as fib_validate_source(), but differs
in several aspects.

The most important difference is that the reverse path filter built into
fib_validate_source uses the oif as iif when performing the reverse
lookup.  We do not do this, as the oif is not yet known by the time the
PREROUTING hook is invoked.

We can't wait until FORWARD chain because by the time FORWARD is invoked
ipv4 forward path may have already sent icmp messages is response
to to-be-discarded-via-rpfilter packets.

To avoid the such an additional lookup in PREROUTING, Patrick McHardy
suggested to attach the path information directly in the match
(i.e., just do what the standard ipv4 path does a bit earlier in PREROUTING).

This works, but it also has a few caveats. Most importantly, when using
marks in PREROUTING to re-route traffic based on the nfmark, -m rpfilter
would have to be used after the nfmark has been set; otherwise the nfmark
would have no effect (because the route is already attached).

Another problem would be interaction with -j TPROXY, as this target sets an
nfmark and uses ACCEPT instead of continue, i.e. such a version of
-m rpfilter cannot be used for the initial to-be-intercepted packets.

In case in turns out that the oif is required, we can add Patricks
suggestion with a new match option (e.g. --rpf-use-oif) to keep ruleset
compatibility.

Another difference to current builtin ipv4 rpfilter is that packets subject to ipsec
transformation are not automatically excluded. If you want this, simply
combine -m rpfilter with the policy match.

Packets arriving on loopback interfaces always match.

Subject: [PATCH 1158/1958] e1000e: Avoid wrong check on TX hang

Based on the original patch submitted my Michael Wang
<wangyun@linux.vnet.ibm.com>.
Descriptors may not be write-back while checking TX hang with flag
FLAG2_DMA_BURST on.
So when we detect hang, we just flush the descriptor and detect
again for once.

-v2 change 1 to true and 0 to false and remove extra ()

Subject: [PATCH 1159/1958] e1000e: hitting BUG_ON() from napi_enable

Based on a patch from Mike McElroy created against the out-of-tree e1000e
driver:

Hitting the BUG_ON in napi_enable(). Code inspection shows that this can
only be triggered by calling napi_enable() twice without an intervening
napi_disable().

I saw the following sequence of events in the stack trace:

1) We simulated a cable pull using an Extreme switch.
2) e1000_tx_timeout() was entered.
3) e1000_reset_task() was called. Saw the message from e_err() in the
console log.
4) e1000_reinit_locked was called. This function calls e1000_down() and
e1000_up(). These functions call napi_disable() and napi_enable()
respectively.
5) Then on another thread, a monitor task saw carrier was down and executed
'ip set link down' and 'ip set link up' commands.
6) Saw the '_E1000_RESETTING'warning fron the e1000_close function.
7) Either the e1000_open() executed between the e1000_down() and e1000_up()
calls in step 4 or the e1000_open() call executed after the e1000_up()
call.  In either case, napi_enable() is called twice which triggers the
BUG_ON.

Subject: [PATCH 1161/1958] ixgbe: DCBnl set_all, order of operations fix

The order of operations is important in DCBnl set_all(). When FCoE
is configured it uses the up2tc map to learn which queues to configure
the hardware offloads on. Therefore we need to setup the map before
configuring FCoE.

This is only seen when the both up2tc mappings and APP info are
configured simultaneously.

From 43497cc21889725a0fa0dcea1ce72ec567796f3a Mon Sep 17 00:00:00 2001
From: John Fastabend <john.r.fastabend@intel.com>
Date: Sat, 12 Nov 2011 01:12:22 +0000
Subject: [PATCH 1162/1958] ixgbe: DCB: IEEE transitions may fail to reprogram
 hardware.

Transitioning through an IEEE DCBX version from a CEE DCBX
and back (CEE->IEEE->CEE) may leave IEEE attributes programmed
in the hardware. DCB uses a bit field in the set routines to
determine which attributes PG, PFC, APP need to be reprogrammed.
This is needed because user flow allows queueing a series
of changes and then reprogramming the hardware with the
entire set in one operation.

When transitioning from IEEE DCBX mode back into CEE DCBX
mode the PG and PFC bits need to be set so the possibly

different CEE attributes get programmed into the device.

This patch fixes broken logic that was evaluating to 0
and never setting any bits. Further this removes some
checks for num_tc in set routines. This logic only worked
when the number of traffic classes and user priorities
were equal. This is no longer the case for X540 devices.
Besides we can trust user input in this case if the
device is incorrectly configured the DCB bandwidths will
be incorrectly mapped but no OOPs, BUG, or hardware
failure will occur.

Subject: [PATCH 1165/1958] infiniband: addr: Consolidate code to fetch
 neighbour hardware address from dst.

IPV4 should do exactly what the IPV6 code does here, which is
use the neighbour obtained via the dst entry.

And now that the two code paths do the same thing, use a common
helper function to perform the operation.

Subject: [PATCH 1166/1958] cxgb3: Rework t3_l2t_get to take a dst_entry
 instead of a neighbour.

This way we consolidate the RCU locking down into the place where it
actually matters, and also we can make the code handle
dst_get_neighbour_noref() returning NULL properly.

Subject: [PATCH 1172/1958] infiniband: ipoib: Sanitize neighbour handling in
 ipoib_main.c

Reduce the number of dst_get_neighbour_noref() calls within a single
call chain.  Primarily by passing the neighbour pointer down to the
helper functions.

Handle dst_get_neighbour_noref() returning NULL in ipoib_start_xmit()
by incrementing the dropped counter and freeing the packet.  We don't
want it to fall through into the ARP/RARP/multicast handling, since
that should only happen when skb_dst() is NULL.

Subject: [PATCH 1174/1958] caif: Add support for CAIF over CDC NCM USB
 interface
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

NCM 1.0 does not support anything but Ethernet framing, hence
CAIF payload will be put into Ethernet frames.

Discovery is based on fixed USB vendor 0x04cc (ST-Ericsson),
product-id 0x230f (NCM). In this variant only CAIF payload is sent over
the NCM interface.

The CAIF stack (cfusbl.c) will when USB interface register first check if
we got a CDC NCM USB interface with the right VID, PID.
It will then read the device's Ethernet address and create a 'template'
Ethernet TX header, using a broadcast address as the destination address,
and EthType 0x88b5 (802.1 Local Experimental - vendor specific).

A protocol handler for 0x88b5 is setup for reception of CAIF frames from
the CDC NCM USB interface.

Subject: [PATCH 1175/1958] caif: Add support for flow-control on device's
 tx-queue
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Flow control is implemented by inspecting the qdisc queue length
in order to detect potential overflow on the TX queue. When a threshold
is reached flow-off is sent upwards in the CAIF stack. At the same time
the skb->destructor is hi-jacked by orphaning the SKB and the original
destructor is replaced with a "flow-on" callback. When the "hi-jacked"
SKB is consumed the queue should be empty, and the "flow-on" callback
is called and xon is sent upwards in the CAIF stack.

Subject: [PATCH 1176/1958] caif: Stash away hijacked skb destructor and call
 it later
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch adds functionality for avoiding orphaning SKB too early.
The original skb is stashed away and the original destructor is called
from the hi-jacked flow-on callback. If CAIF interface goes down and a
hi-jacked SKB exists, the original skb->destructor is restored.

Subject: [PATCH 1177/1958] tcp: fix tcp_trim_head()

commit f07d960df3 (tcp: avoid frag allocation for small frames)
breaked assumption in tcp stack that skb is either linear (skb->data_len
== 0), or fully fragged (skb->data_len == skb->len)

tcp_trim_head() made this assumption, we must fix it.

Thanks to Vijay for providing a very detailed explanation.

Subject: [PATCH 1188/1958] bnx2x: fix crash while ethtool -t

commit 2df1a70aaf70e8dff11b89b938a5f317556ee640  "bnx2x: Support
for byte queue limits" has introduced an asymmetry in usage of
netdev_tx_completed_queue and netdev_tx_sent_queue. Missing
call to netdev_tx_sent_queue causes the crash during ethtool -t.

The patch adds the missing call.

Subject: [PATCH 1192/1958] inet_diag: Partly rename inet_ to sock_

The ultimate goal is to get the sock_diag module, that works in
family+protocol terms. Currently this is suitable to do on the
inet_diag basis, so rename parts of the code. It will be moved
to sock_diag.c later.

Subject: [PATCH 1195/1958] inet_diag: Switch from _GETSOCK to IPPROTO_ numbers

Sorry, but the vger didn't let this message go to the list. Re-sending it with
less spam-filter-prone subject.

When dumping the AF_INET/AF_INET6 sockets user will also specify the protocol,
so prepare the protocol diag handlers to work with IPPROTO_ constants.

Date: Tue, 6 Dec 2011 07:58:03 +0000
Subject: [PATCH 1196/1958] sock_diag: Initial skeleton

When receiving the SOCK_DIAG_BY_FAMILY message we have to find the
handler for provided family and pass the nl message to it.

This patch describes an infrastructure to work with such nandlers
and implements stubs for AF_INET(6) ones.

Subject: [PATCH 1197/1958] inet_diag: Introduce new inet_diag_req header

This one coinsides with the sock_diag_req in the beginning and
contains only used fields from its previous analogue.

The existing code is patched to use the _compat version of it
for now.

Also fix the bytecode calculation to find one at proper offset.

Subject: [PATCH 1200/1958] inet_diag: Introduce socket family checks

The new API will specify family to work with. Teach the existing
socket walking code to bypass not interesting ones.

To preserve compatibility with existing behavior the _compat code
sets interesting family to AF_UNSPEC to dump them all.

Subject: [PATCH 1201/1958] inet_diag: Cleanup type2proto last user

Now all the code works with sock_diag_req-compatible structs, so it's
possible to stop using the inet_diag_type2proto in inet_csk_diag_fill.
Pass the inet_diag_req into it and use the sdiag_protocol field. At the
same time remove the explicit ext argument, since it's also on the req.

However, this conversion is still required in _compat code, so just move
this routine, not remove.

Subject: [PATCH 1207/1958] mac80211: Add HT operation modes for IBSS

The HT mode is set by iw (previous patchsets).
The interface is set into the specified HT mode.
HT mode and capabilities are announced in beacons.

If we add a station that uses HT also, the fastest matching HT mode will
be used for transmission. That means if we are using HT40+ and we add a station
running on HT40-, we would transfer at HT20.

If we join an IBSS with HT40, but the secondary channel is not
available, we will fall back into HT20 as well.

Allow frame aggregation to start in IBSS mode.

Subject: [PATCH 1208/1958] rtl8192c: Do not log firmware load message unless
 actually done

A previous commit fixed a problem whereby the rtl8192c driver loaded the
firmware from disk many times; however, the log message was not moved.

Subject: [PATCH 1222/1958] iwlwifi: replace iwl_priv reference with iwl_trans
 for ucode.

Replace the references to the iwl_priv structure with the iwl_trans
structure as the priv structure is never referenced other than to
access the trans structure.  Rename from iwlagn to iwl.

Subject: [PATCH 1225/1958] mac80211: fix retransmit

This fixes another regression from my "pass all
fragments to driver at once" patches -- if the
packet is being retransmitted then we don't go
through all handlers, but we still need to move
it to the skbs list, otherwise we run into the
first warning in __ieee80211_tx() and leak the
skb.

Subject: [PATCH 1226/1958] mac80211: accept public action frames with
 mismatched BSSID

Arik's patch "mac80211: allow action frames with unknown
BSSID in GO mode" allowed any action frames in P2P mode
to go through, but only to cooked monitor interfaces as
the IEEE80211_RX_RA_MATCH was still cleared. As a result
my no-monitor patches broke invitation responses.

Instead of allowing any action frames in P2P GO mode to
go through with a wrong BSSID like that patch did, allow
all public action frames. They will never be processed
by mac80211, but can be reported via nl80211 then.

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

Raising wake before flushing FIFO and lowering it after caused a
spike on AC wake that were sometimes detected and acted upon by the
modem. Fixed this by remove wake line modification when flushing FIFO.

Various bugfixes for caif_shmcore.c:
- fix deadlocks due to improper usage of spin-lock
- add missing spin-lock init
- don't call dev_kfree_skb() with irqs disabled,
  use dev_kfree_skb_irq() instead.
- fix potential skb null pointer de-reference.

BUG_ON is too strict in a number of circumstances,
use WARN_ON instead. Protocol errors should not halt the system.

Subject: [PATCH 1239/1958] ath9k: always issue a full hw reset after waking up
 from full-sleep mode

After waking up from full sleep, registers are accessible, but rx/tx
typically fails. A fast channel change will not recover from this, so
ensure that a full-sleep -> wake transition is always followed by a full
reset.

The reason why this hasn't created any serious problems yet is that it's
hidden by the (wrong) behavior of enabling/disabling the radio when the
wiphy idle state changes.

Subject: [PATCH 1240/1958] ath9k: rework power state handling

Turning off the radio when mac80211 tells the driver that it's idle is not
a good idea, as idle interfaces might still occasionally scan or send packets.
The only time the radio can be safely turned off is when drv_stop has been
called. In the mean time, use sc->ps_idle only to indicate network sleep vs
full sleep.
Move the LED GPIO changes out of the PCI suspend/resume path, the start/stop
functions already take care of that.

Subject: [PATCH 1241/1958] ath9k: only drop packets in drv_flush when asked to

Recently more places in mac80211 call drv_flush to ensure proper order
for state changes wrt. powersave, channel changes, etc. On some systems
such calls lead to spurious logspam about failing to stop tx dma, as well
as hardware resets that go along with that.
Instead of dropping packets in a place where it's completely unnecessary,
only do it when drop == true.

Subject: [PATCH 1245/1958] ath9k: use config.enable_ani to check if ani should
 be performed

  Currently in ath9k code there is an attempt which is meant to
disable ANI for ar9100 and ar9340. But it doesn't really achieve
this. All it does is disable ANI init and setup (i.e. calls to
ath9k_hw_ani_setup and ath9k_hw_ani_init). Since ath9k_hw_ani_setup is
not called ah->config.ani_poll_interval is never initialized (i.e. it
is always zero) and ath_ani_calibrate always executes ANI procedures
(over uninitialized ANI parameters).
  Moreover, ath_ani_calibrate is being called each 1ms because
common->ani.timer is set to zero interval because
ah->config.ani_poll_interval==0 (and thus smallest value of all
intervals). Normally it should not be called this often.
  This patch changes the code so config.enable_ani is used to check if
ANI should be performed.
  config.enable_ani is initialized to true by default. This patch sets
it to false for ar9100 and ar9340.

  Enable ANI for ar9100 since it seems to be working fine (and as a
matter of fact ANI was always performed for ar9100 since code which
was supposed to disable it didn't achieve this goal).
  This patch sets config.enable_ani to default (true) value for
ar9100.

Subject: [PATCH 1247/1958] wireless: disable wext sysfs by default

This code has been on the list to remove for a long
time, so disable it by default, add a warning to its
Kconfig, and schedule it for removal in 3.5.

The only known dependency, hal, has not required it
since its 0.5.12 release, which was in early 2009
and hal has since been deprecated completely.

Subject: [PATCH 1250/1958] wl12xx: send testmode reply in
 wl1271_tm_cmd_interrogate

wl1271_tm_cmd_interrogate creates a reply skb, but doesn't
send it (and thus just leaks it).
Add the missing cfg80211_testmode_reply() call.

The user can pass broadcast SSID (ssid="") in the list of SSIDs for active scan.
In this case the loop was attempting to match SSIDs in the filter
list to this empty entry and marking them as HIDDEN (sending probe
request) by mistake

Subject: [PATCH 1264/1958] iwlagn: fix TID use bug

The driver everywhere uses max TID count as 9,
which is wrong, it should be 8.

I think the reason it uses 9 here is off-by-one
confusion by whoever wrote this. We do use the
value IWL_MAX_TID_COUNT for "not QoS/no TID"
but that is completely correct even if it is 8
and not 9 since 0-7 are only valid.

As a side effect, this fixes the following bug:

 Open BA session requested for 00:23:cd:16:8a:7e tid 8
 ------------[ cut here ]------------
 kernel BUG at drivers/net/wireless/iwlwifi/iwl-trans-pcie-int.h:350!

We track the load only on 8 TIDs, previously this
was TID_MAX_LOAD_COUNT. Since IWL_MAX_TID_COUNT
is now 8 as well, use that to make the code more
easily understandable.

Subject: [PATCH 1269/1958] bridge: add local MAC address to forwarding table
 (v2)

If user has configured a MAC address that is not one of the existing
ports of the bridge, then we need to add a special entry in the forwarding
table. This forwarding table entry has no outgoing port so it has to be
treated a little differently. The special entry is reported by the netlink
interface with ifindex of bridge, but ignored by the old interface since there
is no usable way to put it in the ABI.

Tg3 has a place to store stats, but doesn't really use it.  This patch
modifies the driver so that stats are saved across chip resets and gets
cleared across close / open calls.

When the MAC address is supplied via platform_data it should be OK as

Also copying the MAC from platform_data to the single 'macaddr'

dual FEC setup.

Subject: [PATCH 1282/1958] net/fec: fix the .remove code
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The .remove code is broken in several ways.
 - mdiobus_unregister() is called twice for the same object in case of dual FEC
 - phy_disconnect() is being called when the PHY is already disconnected
 - the requested IRQ(s) are not freed
 - fec_stop() is being called with the inteface already stopped

 All of those lead to kernel crashes if the remove function is actually used.

From 8e586137e6b63af1e881b328466ab5ffbe562510 Mon Sep 17 00:00:00 2001
From: Jiri Pirko <jpirko@redhat.com>
Date: Thu, 8 Dec 2011 19:52:37 -0500
Subject: [PATCH 1286/1958] net: make vlan ndo_vlan_rx_[add/kill]_vid return
 error value

Let caller know the result of adding/removing vlan id to/from vlan
filter.

In some drivers I make those functions to just return 0. But in those
where there is able to see if hw setup went correctly, return value is
set appropriately.

From: Jiri Pirko <jpirko@redhat.com>
Date: Thu, 8 Dec 2011 04:11:17 +0000
Subject: [PATCH 1287/1958] net: introduce vlan_vid_[add/del] and use them
 instead of direct [add/kill]_vid ndo calls

This patch adds wrapper for ndo_vlan_rx_add_vid/ndo_vlan_rx_kill_vid
functions. Check for NETIF_F_HW_VLAN_FILTER feature is done in this
wrapper.

From 5b9ea6e022e9ba0fe39cb349ac40361f78d5da5b Mon Sep 17 00:00:00 2001

Date: Thu, 8 Dec 2011 04:11:18 +0000
Subject: [PATCH 1288/1958] vlan: introduce vid list with reference counting

This allows to keep track of vids needed to be in rx vlan filters of
devices even if they are used in bond/team etc.

vlan_info as well as vlan_group previously was, is allocated when first
vid is added and dealocated whan last vid is deleted.

vlan_group definition is moved to private header.

So far when vlan id was added to team device befor port was added, this
vid was not added to port's vlan filter. Also after removal, vid stayed
in port device's vlan filter. Benefit of new vlan functions to handle
this work.

Subject: [PATCH 1291/1958] sch_red: Adaptative RED AQM

Adaptative RED AQM for linux, based on paper from Sally FLoyd,
Ramakrishna Gummadi, and Scott Shenker, August 2001 :

http://icir.org/floyd/papers/adaptiveRed.pdf

Goal of Adaptative RED is to make max_p a dynamic value between 1% and
50% to reach the target average queue : (max_th - min_th) / 2

Every 500 ms:
 if (avg > target and max_p <= 0.5)
  increase max_p : max_p += alpha;
 else if (avg < target and max_p >= 0.01)
  decrease max_p : max_p *= beta;

target :[min_th + 0.4*(min_th - max_th),
          min_th + 0.6*(min_th - max_th)].
alpha : min(0.01, max_p / 4)
beta : 0.9
max_P is a Q0.32 fixed point number (unsigned, with 32 bits mantissa)

Changes against our RED implementation are :

max_p is no longer a negative power of two (1/(2^Plog)), but a Q0.32
fixed point number, to allow full range described in Adatative paper.

To deliver a random number, we now use a reciprocal divide (thats really
a multiply), but this operation is done once per marked/droped packet
when in RED_BETWEEN_TRESH window, so added cost (compared to previous
AND operation) is near zero.

dump operation gives current max_p value in a new TCA_RED_MAX_P
attribute.

Example on a 10Mbit link :

tc qdisc add dev $DEV parent 1:1 handle 10: est 1sec 8sec red \
   limit 400000 min 30000 max 90000 avpkt 1000 \
   burst 55 ecn adaptative bandwidth 10Mbit

# tc -s -d qdisc show dev eth3
...
qdisc red 10: parent 1:1 limit 400000b min 30000b max 90000b ecn
adaptative ewma 5 max_p=0.113335 Scell_log 15

Date: Thu, 8 Dec 2011 08:04:07 +0000
Subject: [PATCH 1293/1958] bnx2x: properly initialize L5 features

The code is missing initialization of NO_FCOE_FLAG and NO_ISCSI*FLAGS
when CONFIG_CNIC is not selected.
This causes panic during driver load since commit
1d187b34daaecbb87aa523ba46b92930a388cb21 where NO_FCOE tested
unconditionally (outside #ifdef BCM_CNIC  structure) and
accessed fp[FCOE_IDX] which is not allocated.

Subject: [PATCH 1296/1958] Revert "net: netprio_cgroup: make net_prio_subsys
 static"

This reverts commit 865d9f9f748fdc1943679ea65d9ee1dc55e4a6ae.

This commit breaks the build with CONFIG_NETPRIO_CGROUP=y so
revert it. It does build as a module though. The SUBSYS macro
in the cgroup core code automatically defines a subsys structure
as extern. Long term we should fix the macro. And I need to
fully build test things.

Tested with CONFIG_NETPRIO_CGROUP={y|m|n} with and without
CONFIG_CGROUPS defined.

Subject: [PATCH 1297/1958] sch_red: generalize accurate MAX_P support to
 RED/GRED/CHOKE

Now RED uses a Q0.32 number to store max_p (max probability), allow
RED/GRED/CHOKE to use/report full resolution at config/dump time.

Old tc binaries are non aware of new attributes, and still set/get Plog.

New tc binary set/get both Plog and max_p for backward compatibility,
they display "probability value" if they get max_p from new kernels.

# tc -d  qdisc show dev ...
...
qdisc red 10: parent 1:1 limit 360Kb min 30Kb max 90Kb ecn ewma 5
probability 0.09 Scell_log 15

Make sure we avoid potential divides by 0 in reciprocal_value(), if
(max_th - min_th) is big.

There's an info_size value stored on inet_diag_handler, but for existing
code this value is effectively constant, so just use sizeof(struct tcp_info)
where required.

Subject: [PATCH 1300/1958] inet_diag: Export inet diag cookie checking routine

The netlink diag susbsys stores sk address bits in the nl message
as a "cookie" and uses one when dumps details about particular
socket.

The same will be required for udp diag module, so introduce a heler
in inet_diag module

Subject: [PATCH 1301/1958] inet_diag: Split inet_diag_get_exact into parts

The 1st part locks the inet handler and the 2nd one dump the
inet connection sock.

In the next patches the 1st part will be generalized to call
the socket dumping routine indirectly (i.e. TCP/UDP/DCCP) and
the 2nd part will be used by TCP and DCCP handlers.

Subject: [PATCH 1304/1958] inet_diag: Introduce the inet socket dumping
 routine

The existing inet_csk_diag_fill dumps the inet connection sock info
into the netlink inet_diag_message. Prepare this routine to be able
to dump only the inet_sock part of a socket if the icsk part is missing.

This will be used by UDP diag module when dumping UDP sockets.

Subject: [PATCH 1305/1958] inet_diag: Generalize inet_diag dump and get_exact
 calls

Introduce two callbacks in inet_diag_handler -- one for dumping all
sockets (with filters) and the other one for dumping a single sk.

Replace direct calls to icsk handlers with indirect calls to callbacks
provided by handlers.

Make existing TCP and DCCP handlers use provided helpers for icsk-s.

The UDP diag module will provide its own.

Do the same as TCP does -- iterate the given udp_table, filter
sockets with bytecode and dump sockets into reply message.

The same filtering as for TCP applies, though only some of the
state bits really matter.

Subject: [PATCH 1312/1958] iwlwifi regression in 20111205 merge

  It looks like the regression was introduced between 20111202 and
20111205 (linux-next tree). Symptoms: connection to AP seem to be
established, but no data goes though it in any way. Tested on intel
5300.
  Peek at the changes have shown that it looks like at least part of
the code wasn't merged properly. It was originally committed into
iwl_agn.c but code in question was moved to iwl-mac80211.c.
  This patch puts code in place and my card works again.

Subject: [PATCH 1313/1958] udp_diag: Make it module when ipv6 is a module

Eric Dumazet reported, that when inet_diag is built-in the udp_diag also goes
built-in and when ipv6 is a module the udp6 lookup symbol is not found.

  LD      .tmp_vmlinux1
net/built-in.o: In function `udp_dump_one':
udp_diag.c:(.text+0xa2b40): undefined reference to `__udp6_lib_lookup'
make: *** [.tmp_vmlinux1] Erreur 1

Fix this by making udp diag build mode depend on both -- inet diag and ipv6.

Subject: [PATCH 1321/1958] xen-netfront: delay gARP until backend switches to
 Connected

After a guest is live migrated, the xen-netfront driver emits a gratuitous
ARP message, so that networking hardware on the target host's subnet can
take notice, and public routing to the guest is re-established. However,
if the packet appears on the backend interface before the backend is added
to the target host's bridge, the packet is lost, and the migrated guest's
peers become unable to talk to the guest.

A sufficient two-parts condition to prevent the above is:

(1) ensure that the backend only moves to Connected xenbus state after its
hotplug scripts completed, ie. the netback interface got added to the
bridge; and

(2) ensure the frontend only queues the gARP when it sees the backend move
to Connected.

These two together provide complete ordering. Sub-condition (1) is already
satisfied by commit f942dc2552b8 in Linus' tree, based on commit
6b0b80ca7165 from [1].

In general, the full condition is sufficient, not necessary, because,
according to [2], live migration has been working for a long time without
satisfying sub-condition (2). However, after 6b0b80ca7165 was backported
to the RHEL-5 host to ensure (1), (2) still proved necessary in the RHEL-6
guest. This patch intends to provide (2) for upstream.

The Reviewed-by line comes from [3].

+2.7 Kernel Memory Extension (CONFIG_CGROUP_MEM_RES_CTLR_KMEM)
+
+With the Kernel memory extension, the Memory Controller is able to limit
+the amount of kernel memory used by the system. Kernel memory is fundamentally
+different than user memory, since it can't be swapped out, which makes it
+possible to DoS the system by consuming too much of this precious resource.
+
+Some kernel memory resources may be accounted and limited separately from the
+main "kmem" resource. For instance, a slab cache that is considered important
+enough to be limited separately may have its own knobs.
+
+Kernel memory limits are not imposed for the root cgroup. Usage for the root
+cgroup may or may not be accounted.
+
+Memory limits as specified by the standard Memory Controller may or may not
+take kernel memory into consideration. This is achieved through the file
+memory.independent_kmem_limit. A Value different than 0 will allow for kernel
+memory to be controlled separately.
+
+When kernel memory limits are not independent, the limit values set in
+memory.kmem files are ignored.
+
+Currently no soft limit is implemented for kernel memory. It is future work
+to trigger slab reclaim when those limits are reached.

From 180d8cd942ce336b2c869d324855c40c5db478ad Mon Sep 17 00:00:00 2001
From: Glauber Costa <glommer@parallels.com>
Date: Sun, 11 Dec 2011 21:47:02 +0000
Subject: [PATCH 1323/1958] foundations of per-cgroup memory pressure
 controlling.

This patch replaces all uses of struct sock fields' memory_pressure,
memory_allocated, sockets_allocated, and sysctl_mem to acessor
macros. Those macros can either receive a socket argument, or a mem_cgroup
argument, depending on the context they live in.

Since we're only doing a macro wrapping here, no performance impact at all is
expected in the case where we don't have cgroups disabled.

Subject: [PATCH 1324/1958] socket: initial cgroup code.

The goal of this work is to move the memory pressure tcp
controls to a cgroup, instead of just relying on global
conditions.

To avoid excessive overhead in the network fast paths,
the code that accounts allocated memory to a cgroup is
hidden inside a static_branch(). This branch is patched out
until the first non-root cgroup is created. So when nobody
is using cgroups, even if it is mounted, no significant performance
penalty should be seen.

This patch handles the generic part of the code, and has nothing
tcp-specific.

Subject: [PATCH 1325/1958] tcp memory pressure controls

This patch introduces memory pressure controls for the tcp
protocol. It uses the generic socket memory pressure code
introduced in earlier patches, and fills in the
necessary data in cg_proto struct.

Subject: [PATCH 1326/1958] per-netns ipv4 sysctl_tcp_mem

This patch allows each namespace to independently set up
its levels for tcp memory pressure thresholds. This patch
alone does not buy much: we need to make this values
per group of process somehow. This is achieved in the
patches that follows in this patchset.

Subject: [PATCH 1327/1958] tcp buffer limitation: per-cgroup limit

This patch uses the "tcp.limit_in_bytes" field of the kmem_cgroup to
effectively control the amount of kernel memory pinned by a cgroup.

This value is ignored in the root cgroup, and in all others,
caps the value specified by the admin in the net namespaces'
view of tcp_sysctl_mem.

If namespaces are being used, the admin is allowed to set a
value bigger than cgroup's maximum, the same way it is allowed
to set pretty much unlimited values in a real box.

Subject: [PATCH 1328/1958] Display current tcp memory allocation in kmem
 cgroup

This patch introduces kmem.tcp.usage_in_bytes file, living in the
kmem_cgroup filesystem. It is a simple read-only file that displays the
amount of kernel memory currently consumed by the cgroup.

This patch introduces kmem.tcp.failcnt file, living in the

memcg resources, this files keeps a counter of how many times
allocation failed due to limits being hit in this cgroup.
The root cgroup will always show a failcnt of 0.

 cgroup

This patch introduces kmem.tcp.max_usage_in_bytes file, living in the
kmem_cgroup filesystem. The root cgroup will display a value equal
to RESOURCE_MAX. This is to avoid introducing any locking schemes in
the network paths when cgroups are not being actively used.

All others, will see the maximum memory ever used by this cgroup.

Subject: [PATCH 1331/1958] netem: add cell concept to simulate special MAC
 behavior

This extension can be used to simulate special link layer
characteristics. Simulate because packet data is not modified, only the
calculation base is changed to delay a packet based on the original
packet size and artificial cell information.

packet_overhead can be used to simulate a link layer header compression
scheme (e.g. set packet_overhead to -20) or with a positive
packet_overhead value an additional MAC header can be simulated. It is
also possible to "replace" the 14 byte Ethernet header with something
else.

cell_size and cell_overhead can be used to simulate link layer schemes,
based on cells, like some TDMA schemes. Another application area are MAC
schemes using a link layer fragmentation with a (small) header each.
Cell size is the maximum amount of data bytes within one cell. Cell
overhead is an additional variable to change the per-cell-overhead
(e.g.  5 byte header per fragment).

Example (5 kbit/s, 20 byte per packet overhead, cell-size 100 byte, per
cell overhead 5 byte):

  tc qdisc add dev eth0 root netem rate 5kbit 20 100 5

Subject: [PATCH 1333/1958] IPVS: Modify the SH scheduler to use weights

Modify the algorithm to build the source hashing hash table to add
extra slots for destinations with higher weight. This has the effect
of allowing an IPVS SH user to give more connections to hosts that
have been configured to have a higher weight.

The reason for the Kconfig change is because the size of the hash table
becomes more relevant/important if you decide to use the weights in the
manner this patch lets you. It would be conceivable that someone might
need to increase the size of that table to accommodate their
configuration, so it will be handy to be able to do that through the
regular configuration system instead of editing the source.

Subject: [PATCH 1336/1958] ath6kl: remove a workaround from
 ath6kl_cfg80211_stop()

There's a workaround in ath6kl_cfg80211_stop() which emits disconnected
even when sme_state was disconnected. This is legacy from the old
staging driver and I can't repoduce the old problem anymore. I assume the
bug got fixed while the driver was cleaned up so let's get
rid of the hack.

This makes it possible to call ath6kl_cfg80211_stop from ath6kl_close()
which happens in a followup patch.

This way it's possible to keep all disconnect logic in one function and
easier to add new functionality, like stopping scheduled scan.

There are some changes to commands called during network interface close,
but there should not be any visible changes in functionality.

Subject: [PATCH 1339/1958] ath6kl: fix value of WOW_FILTER_SSID

According to the firmware engineers WOW_FILTER_SSID is actually the
second bit, not the first.

Subject: [PATCH 1340/1958] ath6kl: fix reading of FW IE capabilities

For some strange reason I used ALIGN() to calculate index to the
buffer. That is totally bogus and wouldn't work when it tried to read
the second bit. Fix it by removing the ALIGN() altogether.

Also check that ie_len is not too short.

Subject: [PATCH 1341/1958] ath6kl: implement scheduled scan

ath6kl firmware supports scheduled scan functionality with the wow ssid
filter. But the firmware does not send any events after scan results
so I had to add a timer which notifies about new scan results.

Sched scan needs firmware version 3.2.0.6 or later. If firmware doesn't
support sched scan the driver will not enable the feature.

Subject: [PATCH 1343/1958] be2net: fix ethtool ringparam reporting

The ethtool "-g" option is supposed to report the max queue length and
user modified queue length for RX and TX queues.  be2net doesn't support
user modification of queue lengths. So, the correct values for these
would be the max numbers.
be2net incorrectly reports the queue used values for these fields.

Subject: [PATCH 1344/1958] be2net: refactor/cleanup vf configuration code

- use adapter->num_vfs (and not the module param) to store the actual
number of vfs created. Use the same variable to reflect SRIOV
enable/disable state. So, drop the adapter->sriov_enabled field.

- use for_all_vfs() macro in VF configuration code

- drop the "vf_" prefix for the fields of be_vf_cfg; the prefix is
redundant and removing it helps reduce line wrap

Subject: [PATCH 1346/1958] mlx4_core: initial header-file changes for SRIOV
 support

These changes will not affect module operation as yet. They
are only to get some structs and enums in place for use by
subsequent patches (making those smaller).

Added here:
* sriov state structs and inlines (mlx4_is_master/slave/mfunc)
* comm-channel and vhcr support structures
* enum values for new FW and comm-channel virtual commands
  (i.e., commands, passed via the comm channel to the PF-driver).
* prototypes for many command wrapper functions (used by the
  PF context for processing FW commands passed to it by the VFs).
* struct mlx4_eqe is moved from eq.c to mlx4.h (it will be used
  by other mlx4_core source files).

Subject: [PATCH 1347/1958] mlx4: Extanding port_mask functionality

Port mask now has additional state.
Port can be set as "none". In this case neither the mlx4_en or mlx4_ib
drivers take ownership of the port.
In multifunction mode there is an option to set the vfs as single ported devices.
(in single function mode, both physical ports belong to same function)

Subject: [PATCH 1348/1958] mlx4_core: Add "native" argument to mlx4_cmd and
 its callers (where needed)

For SRIOV, some Hypervisor commands can be executed directly (native = 1).
Others should go through the command wrapper flow (for tracking resource
usage, for example, or for changing some HCA configurations that slaves
need to be notified of).

This patch sets the groundwork for this capability -- adding the correct
value of "native" in each case.

Note that if SRIOV is not activated, this parameter has no effect.

Subject: [PATCH 1349/1958] mlx4_core: Reduce number of PD bits to 17

When SRIOV is enabled on the chip (at FW burning time),
the HCA uses only 17 bits for the PD. The remaining 7 high-order bits
are ignored.

Change the allocator to return only 17 bits for the PD.  The MSB 7
bits will be used to encode the slave number for consistency
checking later on in the resource tracker.

Subject: [PATCH 1350/1958] net/mlx4_core: Implement the master-slave
 communication channel

When SRIOV is enabled, pf and vfs communicate via shared comm channel.
The vf gets its side of the comm channel via a VF BAR.
Each VF (slave) creates its vHCR (virtual HCA Command Register),
Its DMA address is passed to the PF (master) using Communication Channel Register.
The same Register is used to notify the master of commands posted by the
slaves and for the master to pass events to the slaves, such as command completions
and asynchronous events.

The vHCR format is identical to the HCR format, except for the 'go' and 't' bits,
which are reserved in the vHCR. Posting commands to the vHCR is identical to
the way it is done with the HCR, albeit that the function/PF token fields are
used instead of the HCR go bit.
Specifically:
- When the function prepares a new command in the vHCR, it issues the Post_vHCR_cmd
  communication channel command and toggles the value of the function token;
  when PF token has an equal value, the command has been accepted and a new command may be posted.
- When the PF detects a Post_vHCR_cmd command, it concludes that a new command is available in the vHCR;
  after processing the command, the PF toggles the PF token to match the function token.

When the 'e' bit is not set, the completion of a Post_vHCR_cmd command also indicates
the completion the vHCR command. If, however, the 'e' bit is set, the completion of a
Post_vHCR_cmd command only indicates that the vHCR command has been accepted for execution by the PF.

Function commands are processed by the PF as follows:
-DMA (using the ACCESS_MEM command) the vHCR image into a shadow buffer.
-Validate that the opcode is non-privileged, and that the opcode- and input-modifiers are legal.
-DMA the in-box (if required) into a shadow buffer.
-Validate the command:
	o Resource ranges (e.g., QP ranges).
	o Partition key.
	o Ranges of referenced resources (e.g., CQs within QP contexts).
-If the 'e' bit is set
	o complete the Post_vHCR_cmd command
-Execute the command on the HCR.
-DMA the results to the vHCR out-box (if required).
-If the 'e' bit is set
	o Indicate command completion by generating a completion event using the GEN_EQE command
-Otherwise
	o DMA the command status to the vHCR
	o Complete the Post_vHCR_cmd command

From 5cc914f10851d2dc17005c7d26cdd70adcbecbcd Mon Sep 17 00:00:00 2001
From: Marcel Apfelbaum <marcela@dev.mellanox.co.il>

Subject: [PATCH 1351/1958] mlx4_core: Added FW commands and their wrappers for
 supporting SRIOV

The following commands are added here:
1. QUERY_FUNC_CAP and its wrapper.  This function is used by VFs when
   they start up to receive configuration information from the PF, such
   as resource quotas for this VF, which ports should be used (currently
   two), what protocol is running on the port (currently Ethernet ONLY,
   or port not active).

2. QUERY_PORT and its wrapper. Previously, this FW command was invoked directly
   by the ETH driver (en_port.c) using mlx4_cmd_box. Virtualization is now
   required here (the VF's MAC address must be substituted for the PFs
   MAC address returned by the FW). We changed the invocation
   in the ETH driver to use mlx4_QUERY_PORT, and added the wrapper.

3. QUERY_HCA. Used by the VF to determine how the HCA was initialized.
   For now, we need only the multicast table member entry size
   (log2_mc_table_entry_sz, in the ConnectX PRM).  No wrapper is needed
   here, because the data may be passed as is to the VF without modification).

   In this command, we have added a GLOBAL_CAPS field for passing required
   configuration information from FW to a VF (this field is to allow safely
                   adding new SRIOV capabilities which require support in VF drivers, too).
   Bits will set here by FW in response to PF-driver configuration commands which
   will activate as yet undefined new SRIOV features. The VF will test to see that
   all required capabilities indicated by this field are supported (i.e., if a bit
   is set and the VF driver does not recognize that bit, it must abort
   its initialization).  Currently, no bits are set.

4. Added a CLOSE_PORT wrapper.  The PF context needs to keep track of how many VF contexts
   have the port open.  The PF context will not actually issue the FW close port command
   until the last port user issues a CLOSE_PORT request.

Subject: [PATCH 1352/1958] mlx4_core: srq modifications for SRIOV

SRQs are resources which are allocated and tracked by the PF driver.
In multifunction mode, the allocation and icm mapping is done in
the resource tracker (later patch in this sequence).

To accomplish this, we have "work" functions whose names start with
"__", and "request" functions (same name, no __). If we are operating
in multifunction mode, the request function actually results in
comm-channel commands being sent (ALLOC_RES or FREE_RES).
The PF-driver comm-channel handler will ultimately invoke the
"work" (__) function and return the result.

If we are not in multifunction mode, the "work" handler is invoked
immediately.

Subject: [PATCH 1354/1958] mlx4_core: cq modifications for SRIOV

CQs are resources which are allocated and tracked by the PF driver.
In multifunction mode, the allocation and icm mapping is done in
the resource tracker (later patch in this sequence).

To accomplish this, we have "work" functions whose names start with
"__", and "request" functions (same name, no __). If we are operating
in multifunction mode, the request function actually results in
comm-channel commands being sent (ALLOC_RES or FREE_RES).
The PF-driver comm-channel handler will ultimately invoke the
"work" (__) function and return the result.

If we are not in multifunction mode, the "work" handler is invoked
immediately.

From ea51b377abcdf0f3fab0119879be373bda69afb1 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1355/1958] mlx4_core: mtt modifications for SRIOV

MTTs are resources which are allocated and tracked by the PF driver.
In multifunction mode, the allocation and icm mapping is done in
the resource tracker (later patch in this sequence).

To accomplish this, we have "work" functions whose names start with
"__", and "request" functions (same name, no __). If we are operating
in multifunction mode, the request function actually results in
comm-channel commands being sent (ALLOC_RES or FREE_RES).
The PF-driver comm-channel handler will ultimately invoke the
"work" (__) function and return the result.

If we are not in multifunction mode, the "work" handler is invoked
immediately.

From acba2420f9d20082b17d0cbeb1137fcffe0f5b7e Mon Sep 17 00:00:00 2001
From: Jack Morgenstein <jackm@dev.mellanox.co.il>

Subject: [PATCH 1356/1958] mlx4_core: Add wrapper functions and comm channel
 and slave event support to EQs

Passing async events to slaves:
In SRIOV mode, each slave creates its own async EQ, but only the master can
register directly with the FW to receive async events.  Async events which
should be passed to slaves (such as a WQ_ACCESS_ERROR for a QP owned by a slave)
are generated at the slave by the master using the GEN_EQE FW command.

Wrapper functions: mlx4_MAP_EQ_wrapper
Only the master can map an EQ. The slave commands to map their EQs arrive
at the master via the comm channel.  The master then invokes the wrapper
function to do the work (and enter the resource in the tracking database).

New events: COMM_CHANNEL and FLR
The COMM_CHANNEL event arrives only at the master, and signals that
a slave has posted a command on the comm channel.
The FLR event is generated by the FW when a guest operating a VF
unexpectedly goes down.

Subject: [PATCH 1357/1958] mlx4_core: resource tracking for HCA resources used
 by guests

The resource tracker is used to track usage of HCA resources by the different
guests.

Virtual functions (VFs) are attached to guest operating systems but
resources are allocated from the same pool and are assigned to VFs. It is
essential that hostile/buggy guests not be able to affect the operation of
other VFs, possibly attached to other guest OSs since ConnectX firmware is not
tolerant to misuse of resources.

The resource tracker module associates each resource with a VF and maintains
state information for the allocated object. It also defines allowed state
transitions and enforces them.

Relationships between resources are also referred to. For example, CQs are
pointed to by QPs, so it is forbidden to destroy a CQ if a QP refers to it.

ICM memory is always accessible through the primary function and hence it is
allocated by the owner of the primary function.

When a guest dies, an FLR is generated for all the VFs it owns and all the
resources it used are freed.

The tracked resource types are: QPs, CQs, SRQs, MPTs, MTTs, MACs, RES_EQs,
and XRCDNs.

Subject: [PATCH 1359/1958] mlx4: Traffic steering management support for SRIOV

Let multicast/unicast attaching flow go through resource tracker.
The PF is the one responsible for managing all the steering entries.
Define and use module parameter that determines the number of qps
per multicast group.
Minor changes in function calls according to changed prototype.

From ffe455ad04681f3fc48eef595fe526a795f809a3 Mon Sep 17 00:00:00 2001
From: Eugenia Emantayev <eugenia@mellanox.co.il>
Date: Tue, 13 Dec 2011 04:16:21 +0000
Subject: [PATCH 1360/1958] mlx4: Ethernet port management modifications

The physical port is now common to the PF and VFs.
The port resources and configuration is managed by the PF, VFs can
only influence the MTU of the port, it is set as max among all functions,
Each function allocates RX buffers of required size to meet it's MTU enforcement.
Port management code was moved to mlx4_core, as the mlx4_en module is
virtualization unaware

Move handling qp functionality to mlx4_get_eth_qp/mlx4_put_eth_qp
including reserve/release range and add/release unicast steering.
Let mlx4_register/unregister_mac deal only with MAC (un)registration.

Subject: [PATCH 1361/1958] mlx4_en: Allow communication between functions on
 same host

To enable internal loopback, always fill DMAC in control segment
when transmitting the packet, once this is done, the packet is subject
for loopback for if the DMAC mathces one of the multicast/unicast addresses
registered on the physical port.
In receive path if source MAC is our own MAC and we are not in selftest,
or not in force LB mode - drop this packet.

Subject: [PATCH 1362/1958] mlx4_core: mtts resources units changed to offset

In the previous implementation mtts are managed by:
1. order     - log(mtt segments), 'mtt segment' groups several mtts together.
2. first_seg - segment location relative to mtt table.
In the current implementation:
1. order     - log(mtts) rather than segments
2. offset    - mtt index in mtt table

Note: The actual mtt allocation is made in segments but it is
      transparent to callers.

Rational: The mtt resource holders are not interested on how the allocation
          of mtt is done, but rather on how they will use it.

Subject: [PATCH 1363/1958] mlx4_core: adjust catas operation for SRIOV mode

When running in SRIOV mode, driver should not automatically start/stop
the mlx4_core upon sensing an HCA internal error -- doing this disables/enables
sriov, which will cause the hypervisor to hang if there are running VMs with
attached VFs.

In addition, on VMs the catas process should not run at all, since the HCA
error buffer is not available to VMs in the BARs.

Subject: [PATCH 1364/1958] mlx4_core: Modify driver initialization flow to
 accommodate SRIOV for Ethernet

1. Added module parameters sr_iov and probe_vf for controlling enablement of
   SRIOV mode.
2. Increased default max num-qps, num-mpts and log_num_macs to accomodate
   SRIOV mode
3. Added port_type_array as a module parameter to allow driver startup with
   ports configured as desired.
   In SRIOV mode, only ETH is supported, and this array is ignored; otherwise,
   for the case where the FW supports both port types (ETH and IB), the
   port_type_array parameter is used.
   By default, the port_type_array is set to configure both ports as IB.
4. When running in sriov mode, the master needs to initialize the ICM eq table
   to hold the eq's for itself and also for all the slaves.
5. mlx4_set_port_mask() now invoked from mlx4_init_hca, instead of in mlx4_dev_cap.
6. Introduced sriov VF (slave) device startup/teardown logic (mainly procedures
   mlx4_init_slave, mlx4_slave_exit, mlx4_slave_cap, mlx4_slave_exit and flow
   modifications in __mlx4_init_one, mlx4_init_hca, and mlx4_setup_hca).
   VFs obtain their startup information from the PF (master) device via the
   comm channel.
7. In SRIOV mode (both PF and VF), MSI_X must be enabled, or the driver
   aborts loading the device.
8. Do not allow setting port type via sysfs when running in SRIOV mode.
9. mlx4_get_ownership:  Currently, only one PF is supported by the driver.
   If the HCA is burned with FW which enables more than one PF, only one
   of the PFs is allowed to run.  The first one up grabs a FW ownership
   semaphone -- all other PFs will find that semaphore taken, and the
   driver will not allow them to run.

Subject: [PATCH 1368/1958] ath9k_hw: Fix handling of MCI interrupt

in my previous patches of handling MCI interrupt I overlooked
the case of interrupt status/mask variable being zeroed out in
the below code, so ath_isr does not cache the MCI interrupt
in the intrstatus. finally MCI interrupt handling won't be
handled in ath9k_tasklet for the scheduled interrupts.
Fix this by moving the MCI interrupt code in the appropriate
position in ar9003_hw_get_isr

Subject: [PATCH 1370/1958] cfg80211: Fix race in bss timeout

It is quite possible to run into a race in bss timeout where
the drivers see the bss entry just before notifying cfg80211
of a roaming event but it got timed out by the time rdev->event_work
got scehduled from cfg80211_wq. This would result in the following
WARN-ON() along with the failure to notify the user space of
the roaming. The other situation which is happening with ath6kl
that runs into issue is when the driver reports roam to same AP
event where the AP bss entry already got expired. To fix this,
move cfg80211_get_bss() from __cfg80211_roamed() to cfg80211_roamed().

Subject: [PATCH 1371/1958] mac80211: Purge A-MPDU TX queues before station
 destructions

When a station leaves suddenly while ampdu traffic to that station is still
running, there is a possibility that the ampdu pending queues are not freed due
to a race condition leading to memory leaks. In '__sta_info_destroy' when we
attempt to destroy the ampdu sessions in 'ieee80211_sta_tear_down_BA_sessions',
the driver calls 'ieee80211_stop_tx_ba_cb_irqsafe' to delete the ampdu
structures (tid_tx) and splice the pending queues and this job gets queued in
sdata workqueue. However, the sta entry can get destroyed before the above work
gets scheduled and hence the race.

Purging the queues and freeing the tid_tx to avoid the leak. The better solution
would be to fix the race, but that can be taken up in a separate patch.

 tx status path

Use ieee80211_is_data, ieee80211_is_mgmt and ieee80211_is_first_frag
in the tx status path. This makes the code easier to read and allows us
to remove two local variables: frag and type.

Subject: [PATCH 1377/1958] ath: optimize processing of CTLs for country IEs
 for world roaming cards

When we receive a country IE hint and we have a world roaming card
we can optimize output power further by ensuring that we use the
calibrated data for the country by using that country's own CTL data.
That is -- when world roaming and when we process a country IE we
no longer need to use the lowest output power of all CTLs instead
we use an optimized CTL output power for that specific country.

We accomplish this by copying the regulatory data prior on init
and restoring it when cfg80211 tells us it gets a core hint. Core
hints are only sent on init and when it wants to restore reguulatory
settings. We take advantage of this fact and apply the cached
regulatory data when we get a core hint. When we get a country IE
hint though we process the regulatory data as if programmed for
a specific country.

Subject: [PATCH 1380/1958] brcm80211: fmac: save bus interface structure in
 function 2 device

bus interface was stored in sdio card device. The device pointer
is used as parameter of interface functions between common layer
and bus layer to make the function declaration generic for different
bus type. But the card device is a parent device layer for SDIO
function devices. It doesn't contain all contexts needed by udev.
This patch moves the shared structure to private driver data pointer
of SDIO function 2 device which is more appopriate for net device
and cfg80211 registration.

Subject: [PATCH 1384/1958] bcma: add set/mask macros for 16-bit register
 access

The BCMA header only had definitions for 32-bit register access. Used
those as a template for the 16-bit flavour. Also changed them to inline
functions to be on the safe side. As offset parameter is used twice there
would be a problem when used like this: bcma_set32(core, offset++, val);

Subject: [PATCH 1385/1958] bcma: use static keyword for inline function
 declaration in bcma.h

Just scratching an itch here, but it makes more sense to use the
static keyword if you think about how the compiler treats inline
functions.

From b2ffec46ea230acac52170dd0a747526328d25fe Mon Sep 17 00:00:00 2001
From: Arend van Spriel <arend@broadcom.com>
Date: Thu, 8 Dec 2011 15:06:45 -0800
Subject: [PATCH 1388/1958] brcm80211: smac: use inline access functions for
 struct si_pub fields

Instead of directly accessing the fields in struct si_pub the driver
now uses inline access functions. This is in preparation of the bcma
integration as a lot of information will be provided by bcma module.

Subject: [PATCH 1389/1958] brcm80211: smac: change from pci device driver to
 bcma device driver

A new bus driver called "bcma" has been introduced into the kernel tree
which considers the Broadcom AMBA chip interconnect as a bus. Each core in
the chip is a bcma device. This commit changes brcms_mac80211.c into
a bcma device driver.

Subject: [PATCH 1390/1958] brcm80211: smac: change attach interfaces in main.c
 for bcma support

The driver is probed through bcma which provides a device representing
the core. This device is now passed in brcms_c_attach and brcms_b_attach
functions.

Subject: [PATCH 1391/1958] brcm80211: smac: rename struct si_info field pbus
 to pcibus

When moving to bcma usage there are two busses in play. The pci bus
connecting the device to the host and the bcma bus connecting the
cores in the device. To distinguish this the attribute pbus has been
renamed to a more explicit name, ie. pcibus.

Subject: [PATCH 1393/1958] brcm80211: smac: remove enumeration rom parsing
 function

The core enumeration rom is already parsed by the bcma bus driver and
there is no need to repeat the exercise. The ai_scan() function still
exists but is targetted for removal as well.

Subject: [PATCH 1394/1958] brcm80211: smac: use bcma core register access
 functions for 802.11 core

The driver now uses the bcma register access functions to read and
write the registers on the 802.11 core. The dma and phy code need
to be modified next and access to the other cores. That will be done
in coming patches.

Subject: [PATCH 1395/1958] brcm80211: smac: use DMA-API calls for descriptor
 allocations

Using BCMA hides the specifics about the host interface. The
driver is now using the DMA-API to do dma related calls. BCMA
provides the device object to use in the DMA-API calls.

Subject: [PATCH 1398/1958] brcm80211: smac: remove SI_FAST() macro usage

The use of SI_FAST() macro interferes with the BCMA integration as
it causes BCMA and aiutils.c to get out of sync on what the current
core is. When everything is using BCMA we will try to add SI_FAST
functionality to BCMA to avoid unnecessary core switching.

Subject: [PATCH 1399/1958] brcm80211: smac: replace ai_corereg() function with
 ai_cc_reg()

The ai_corereg() function is only used in the driver to safely
access the chipcommon core. The function has been renamed to
ai_cc_reg() removing the need to provide a core index parameter.

Subject: [PATCH 1402/1958] brcm80211: smac: use bcma core access functions in
 nicpci.c

Code in nicpci.c now uses the PCI(E) core as provided by the BCMA
bus driver to configure that core.

Subject: [PATCH 1403/1958] mwifiex: failure case handling for PCIe events

Event buffers for PCIe interface are allocated during driver
initialisation, and respective physical addresses are sent to FW
in *_PCIE_DESC_DETAILS command so that FW can do DMA. These buffers
will be freed while unloading the driver. Therefore we should not
free them in event handling error path. Also we should skip next
pending events in failure case.

Also fixed 'returning -1 instead of -ENOMEM is sloppy' warnings.

Leaving leisure power save mode can take some time, so it's better to
perform that action in process context with interrupts enabled. This
patch changes lps_leave tasklet to work.

Subject: [PATCH 1416/1958] rtlwifi: merge ips,lps spinlocks into one mutex

With previous patch "rtlwifi: use work for lps" we can now use mutex for
protecting ps mode changing critical sections. This fixes running system
with interrupts disabled for long time.

Merge ips_lock and lps_lock as they seems to protect the same data
structures (accessed in rtl_ps_set_rf_state() function).

Subject: [PATCH 1417/1958] mac80211: Do not request FIF_BCN_PRBRESP_PROMISC
 for HW scan.

ieee80211_configure_filter code used local->scanning as a boolean
value when it was a bit mask. Bits SCAN_COMPLETED, SCAN_ABORTED
should not set FIF_BCN_PRBRESP_PROMISC filter.

SCAN_HW_SCANNING should not set FIF_BCN_PRBRESP_PROMISC either,
as there is no explicit filter configuration request from
scan code. If a driver requires FIF_BCN_PRBRESP_PROMISC mode
during HW scanning, it's up to the driver to temporary enable it.

Similar mistake was fixed also in ieee80211_hw_config (power
configuration code).

notifier makes the notifer ignore this event, which
causes wrong arp filter configuration later on.

 ai_findcore()

Instead of returning the core index the function now returns
the bcma device for the requested core id. This function is
now exposed in the header file.

Subject: [PATCH 1426/1958] brcm80211: smac: use bcma core access function in
 srom.c

The code in srom.c now uses the core access function provided by
BCMA so no need to pass __iomem pointer any longer.

Subject: [PATCH 1428/1958] brcm80211: smac: use bcma core access functions in
 aiutils.c

The code in aiutils.c now uses the BCMA function for control the
registers in the device cores.

Subject: [PATCH 1429/1958] brcm80211: smac: remove register access macro
 definitions

The register access macros like R_REG/W_REG/etc. are no longer
needed as the driver uses the BCMA provided functions.

The macros were used to assure that the correct core was accessed in
the ISR, but register access is now done giving the explicit core so
no need to change interrupt state.

The function ai_switch_core() is no longer needed and its counterpart
ai_restore_core() as well, because interrupts disabling is not needed
anymore.

From 3b758a68402fc5b1c2dbc246595dbdc062bf0da9 Mon Sep 17 00:00:00 2001
From: Arend van Spriel <arend@broadcom.com>
Date: Mon, 12 Dec 2011 15:15:09 -0800
Subject: [PATCH 1434/1958] brcm80211: smac: remove mapped core related
 function from aiutils.c

In aiutils.c the selected core was maintained by its index number. This
is obsolete using BCMA functions so several functions using that index
have been removed.

Subject: [PATCH 1436/1958] brcm80211: smac: cleanup buscore handling in
 aiutils.c

Instead of storing the buscore information now the BCMA core device
is kept for quick reference in si_info structure.

Subject: [PATCH 1437/1958] brcm80211: smac: register with bcma for specific
 802.11 core revisions

The brcmsmac driver has been verified on chipsets that were supported
when it was a pci device driver, ie. bcm4313, bcm43224, and bcm43225.
This patch restricts the driver to 802.11 core revisions that are found
in these chipsets.

It's simpler to just keep these things out until there is a real user
of them, so we can see what the needs actually are, rather than keep
these things around as useless overhead.

Subject: [PATCH 1440/1958] ipv6: If neigh lookup fails during icmp6 dst
 allocation, propagate error.

Don't just succeed with a route that has a NULL neighbour attached.
This follows the behavior of addrconf_dst_alloc().

Allowing this kind of route to end up with a NULL neigh attached will
result in packet drops on output until the route is somehow
invalidated, since nothing will meanwhile try to lookup the neigh
again.

A statistic is bumped for the case where we see a neigh-less route on
output, but the resulting packet drop is otherwise silent in nature,
and frankly it's a hard error for this to happen and ipv6 should do
what ipv4 does which is say something in the kernel logs.

The original code generates a Sparse warning:
net/8021q/vlan_core.c:336:9:
	error: incompatible types in comparison expression (different address spaces)

It's ok to dereference __rcu pointers here because we are holding the
RTNL lock.  I've added some calls to rtnl_dereference() to silence the
warning.

AR6003 family use uart_tx=8 and refclk=26Mhz by default, and AR6004 family
uses different uart_tx pin and could also support various xtal source,
moves these per hw configuration.

commit b099ce2602d806 (net: Batch inet_twsk_purge) added rcu protection
on tw_net for no obvious reason.

struct net are refcounted anyway since timewait sockets escape from rcu
protected sections. tw_net stay valid for the whole timwait lifetime.

This also removes a lot of sparse errors.

Subject: [PATCH 1450/1958] ath6kl: support for P2P mgmt operations on station
 interface

This patch enables support for doing P2P management operations like device
discovery on top of a station interface. After group formation, the station
interface will become a P2P GO/client interface as the case may be.

This feature requires modifications to a couple of existing WMI structures and
therefore new command ids and structures have been defined in order to be
compatible with older firmware versions and other chips. The exception here is
the wmi_connect_cmd. Adding a new field to the end of the structure will not
cause any issues with previous firmware versions since firmware only checks for
minimum length of the command. The other structures are of variable length,
hence it was not possible to add new fields to the end.

The new command ids have to be added to the end of enum wmi_cmd_id, so it has
updated to match the firmware.

The driver will support both the 'old' and the 'new' commands for a while by
checking the firmware capabilities.

From 00918d33c0e9966392e5a13aeacd712b9da473c9 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Tue, 13 Dec 2011 17:22:05 +0100
Subject: [PATCH 1451/1958] nl80211: accept testmode dump with netdev

All nl80211 commands that need only the wiphy
still allow identifying it by giving an interface
index, except, as Kenny pointed out, the testmode
dump support.

Fix this by looking up the wiphy via the ifidx in
this case as well.

From 38c9d6641ff0664911aebe4ba67124f28169a972 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1452/1958] mwifiex: remove cfg_workqueue

cfg_workqueue was added to notify cfg80211 that scan, connect
or disconnect is done by calling respective completion handlers.
We can avoid use of this workqueue by calling those handlers
from other places.
1) Call connect, disconnect completion handlers in their callback
   functions.
   ex. Call cfg80211_connect_result() in mwifiex_cfg80211_connect()
2) Call scan completion handler after parsing response of last scan
   command in a queue.

After removing the workqueue, variables (assoc_request etc.) and
checks used for mutual exclusion become redundant. Those are also
removed in this patch.

Subject: [PATCH 1454/1958] rt2x00: Make use of ieee80211_free_txskb in tx path

ieee80211_free_txskb should be used when dropping a frame in the device
rx path such that mac80211 knows about this frame being dropped.

Subject: [PATCH 1456/1958] NFC: Add tx skb allocation routine

This is a factorization of the current rawsock tx skb allocation routine,
as it will be used by the LLCP code.
We also rename nfc_alloc_skb to nfc_alloc_recv_skb for consistency sake.

 release notifier

The netlink notifier is atomic so we must not sleep in that context.
Also we know that Any netlink packets arriving to us will be purged when
the notifier is called, so we don't need to take the mutex.

Subject: [PATCH 1460/1958] NFC: Set and get DEP general bytes

Without an API for setting and getting the local and remote general bytes,
drivers won't be able to properly establish a DEP link.
This API also allows them to propagate the remote general bytes they get
from the DEP link establishment up to the LLCP layer.

Subject: [PATCH 1462/1958] NFC: Initial LLCP support

This patch is an initial implementation for the NFC Logical Link Control
protocol. It's also known as NFC peer to peer mode.
This is a basic implementation as it lacks SDP (services Discovery
Protocol), frames aggregation support, and frame rejecion parsing.
Follow up patches will implement those missing features.
This code has been tested against a Nexus S phone implementing LLCP 1.0.

Subject: [PATCH 1464/1958] wl12xx: don't write out of bounds when hlid >
 WL12XX_MAX_LINKS

We should not get an hlid value bigger than WL12XX_MAX_LINKS from
wl1271_rx_handle_data().  We have a WARN_ON in case it happens.  But
despite the warning, we would still go ahead and write the hlid bit
into active_hlids (a stack variable).  This would cause us to
overwrite other data in the stack.

To avoid this problem, we now skip the write when issuing the warning,
so at least we don't corrupt data.

Subject: [PATCH 1465/1958] wl12xx: call extended radio parameters for wl127x
 AP mode

We need to set the extended radio parameters for wl127x only.
Currently, we were only calling this command with wl127x STA mode, but
we should also do it for AP mode.

Move the call to the extended radio paramaters to the common hw_init
and use a single if for the chip type to do everything at once.

Use the newly introduced ieee80211_free_txskb() instead
of dev_kfree_skb() for failed tx packets.

Additionally, if the skb is a dummy packet, re-enqueue
it (as the fw expects it) instead of freeing it.

Subject: [PATCH 1470/1958] wl12xx: alloc buffer in driver_state_read to
 prevent compilation warning

When compiling wl12xx for x86, there was a warning complaining about
the size of the buffer we were allocating in the stack:

drivers/net/wireless/wl12xx/debugfs.c: In function 'driver_state_read':
drivers/net/wireless/wl12xx/debugfs.c:380:1: warning: the frame size of 1040 bytes is larger than 1024 bytes

To prevent this, allocate the buffer in the heap instead.

Subject: [PATCH 1479/1958] cfg80211: validate nl80211 station handling better

The nl80211 station handling code is a bit messy
and doesn't do a lot of validation. It seems like
this could be an issue for drivers that don't use
mac80211 to validate everything.

As cfg80211 doesn't keep station state, move the
validation of allowing supported_rates to change
for TDLS only in station mode to mac80211.

Subject: [PATCH 1481/1958] mac80211: use station mutex in configuration

There's no need to use RCU here, we can just lock
the station mutex instead. This allows the code
to sleep, which is necessary for later patches.

Subject: [PATCH 1482/1958] mac80211: refactor station state transitions

Station entries can have various states, the most
important ones being auth, assoc and authorized.
This patch prepares us for telling the driver about
these states, we don't want to confuse drivers with
strange transitions, so with this we enforce that
they move in the right order between them (back and
forth); some transitions might happen before the
driver even knows about the station, but at least
runtime transitions will be ordered correctly.

As a consequence, IBSS and MESH stations will now
have the ASSOC flag set (so they can transition to
AUTHORIZED), and we can get rid of a special case
in TX processing.

When freeing a station, unwind the state so that
other parts of the code (or drivers later) can rely
on the transitions.

Subject: [PATCH 1483/1958] mac80211: count authorized stations per BSS

Currently, each AP interface will send multicast
traffic if any interface has a station entry even
if that station entry is allocated only. With the
new station state management we can easily fix it
by adding a counter that counts each authorized
station only and send multicast traffic only when
the correct interface has at least one authorized
station.

Subject: [PATCH 1485/1958] mac80211: delay IBSS station insertion

In order to notify drivers and simplify the station
management code, defer IBSS station insertion to a
work item and don't do it directly while receiving
a frame.

This increases the complexity in IBSS a little bit,
but it's pretty straight forward and it allows us
to reduce the station management complexity (next
patch) considerably.

Subject: [PATCH 1486/1958] mac80211: reduce station management complexity

Now that IBSS no longer needs to insert stations
from atomic context, we can get rid of all the
special cases for that, and even get rid of the
sta_lock (though it needs to stay as tim_lock.)

This makes the station management code much more
straight-forward.

Subject: [PATCH 1487/1958] mac80211: Use appropriate TID for sending BAR,
 ADDBA and DELBA frames

Currently BAR, ADDBA and DELBA frames are always sent using AC_VO. If
the TID for which a BA session is established is assigned to a different
queue BAR, ADDBA and DELBA frames can "overtake" frames of the according
BA session.

Hence, always put BA session related frames into the same queue as the
BA sessions data frames.

Subject: [PATCH 1490/1958] ath9k: change maximum software retransmission
 handling

Instead of limiting a subframe to 10 A-MPDU software transmission attempts,
count hardware retransmissions as well and raise the limit a bit. That way
there will be fewer software retransmission attempts when traffic suffers
from lots of hardware retransmissions.

Subject: [PATCH 1493/1958] ath9k: remove bogus sequence number increment

tid->seq_next is initialized on A-MPDU start anyway, and the comment next
to this chunk of code seems to be bogus as well.

Subject: [PATCH 1494/1958] ath9k: simplify tx locking

Instead of releasing and taking back the lock over and over again in the
tx path, hold the lock a bit longer, requiring much fewer lock/unlock pairs.
This makes locking much easier to review and should not have any noticeable
performance/latency impact.

In ai_attach(), space is allocated for an si_info struct. Immediately
after the allocation, routine ai_doattach() is called and that allocated
space is set to zero. As no other routine calls ai_doattach(), kzalloc()
can be utilized.

Subject: [PATCH 1499/1958] ath9k_hw: add DFS testing check

In order to enable DFS upstream we want to be sure
DFS has been tested for each chipset. Push for public
documentation of the requirements we want in place and
allow for enabling each chipset through a single upstream
commit.

Subject: [PATCH 1500/1958] ath9k: add DFS radar pulse processing

This initial DFS module provides basic functionality to deal
with radar pulses reported by the Atheros DFS HW pulse detector.

The reported data is evaluated and basic plausibility checks
are performed to filter false pulses. Passing radar pulses are
forwarded to pattern detectors which are not yet implemented.

(Some modifications to actually use ATH9K_DFS_DEBUGFS based on comments
from Julian Calaby <julian.calaby@gmail.com>. -- JWL)

Subject: [PATCH 1501/1958] brcm80211: smac: precendence bug in
 wlc_phy_attach()

Negate has higher precendence than compare and since neither zero nor
one are equal to four or eight the original condition is always false.

Subject: [PATCH 1503/1958] ath9k: validate for non-zero BSSID

before concluding that the recieved beacon is for us, let us make sure
that the BSSID is non-zero. when I configured ad-hoc mode as creator and
left it for some time without joining I found we recieved few frames whose
BSSID is zero, which we concluded wrongly as 'my_beacons'

Fix a few minor issues with wmediumd_pid:
a) make static
b) use u32 to match the snd_pid type
c) use ACCESS_ONCE since we don't lock it
d) don't explicitly initialize to 0

Subject: [PATCH 1506/1958] cfg80211: allow following country IE power for
 custom regdom cards

By definition WIPHY_FLAG_STRICT_REGULATORY was intended to allow the
wiphy to adjust itself to the country IE power information if the
card had no regulatory data but we had no way to tell cfg80211 that if
the card also had its own custom regulatory domain (these are typically
custom world regulatory domains) that we want to follow the country IE's
noted values for power for each channel. We add support for this and
document it.

This is not a critical fix but a performance optimization for cards
with custom regulatory domains that associate to an AP with sends
out country IEs with a higher EIRP than the one on the custom
regulatory domain. In practice the only driver affected right now
are the Atheros drivers as they are the only drivers using both
WIPHY_FLAG_STRICT_REGULATORY and WIPHY_FLAG_CUSTOM_REGULATORY --
used on cards that have an Atheros world regulatory domain. Cards
that have been programmed to follow a country specifically will not
follow the country IE power. So although not a stable fix distributions
should consider cherry picking this.

Subject: [PATCH 1507/1958] cfg80211: Restore orig channel values upon
 disconnect

When we restore regulatory settings the world regulatory domain
is properly reset on cfg80211 (or user prefered regulatory domain)
but we were never setting back channel values for drivers that use
WIPHY_FLAG_CUSTOM_REGULATORY. Set these values up again by using
the orig_ channel parameters.

This fixes restoring custom regulatory settings upon disconnect
events.

Subject: [PATCH 1512/1958] iwlwifi: don't count the tfds in HW queue any more

Since packets sent to an RA / TID in AGG are sent from a
separate HW Tx queue, we may get into a race:
the regular queue isn't empty while we already begin to
send packets from the AGG queue. This would result in sending
packets out of order.

In order to cope with this, mac80211 waits until the driver
reports that the legacy queue is drained before it can send
packets to the AGG queue. During that time, mac80211 buffers
packets for the driver. These packets will be sent in order
after the driver reports it is ready.

The way this was implemented in the driver is as follows:
We held a counter that monitors the number of packets for
an RA / TID in the HW queues. When this counter reached 0,
we knew that the HW queues were drained and we reported to
mac80211 that were ready to proceed.

This patch changes the implementation described above. We
now remember what is the wifi sequence number of the first
packet that will be sent in the AGG queue (lets' call it
ssn). When we reclaim the packet before ssn, we know that
the queue is drained, and we are ready to proceed.

This will allow us to move this logic in the upper layer and
eventually remove the tid_data from the shared area.

Subject: [PATCH 1513/1958] iwlwifi: we can wake SW queues even when draining
 HW queues

In the very first implementation of HT, the driver was responsible
for the queueing: stopping and waking the queues while the HW queues
where being drained. In this implementation, we had to deal with the
case where we were draining the AGG queue because we wanted to tear
down the BA agreement.
In the normal flow (when we don't drain any HW queue), when packets
are reclaimed, we wake the SW queue in case the SW queue was stopped
which can happen when the HW queues are too full.
While draining a HW queue, we must make sure that we don't wake the
SW queue, since the whole point of the draining is to empty totally
the HW queue and not only get below a certain threshold.
This is why there is condition in the reclaim function:

if (NOT EMPTYING DELBA)
	wake the SW queue is applicable

Since then, a lot has changed and mac80211 is now able to buffer
packets that are being sent to a packet list that will be spliced
after the driver has reported it has drained its HW queues.
Hence, there is no need for the for aforementioned if, and we can
safely wake up the queue even if we are draining HW queues.
Removing this if, also allows us to remove the wake_queue in
check_empty that was there in order to deal with a corner case
created by the if.

In the same spirit as the previous patch. Eventually this will
allow us to remove the tid_data knowledge from the transport layer.

Subject: [PATCH 1518/1958] iwlwifi: tid_data logic move to upper layer -
 check_empty

The tid_data is not related to the transport layer, so move
the logic that depends on it to the upper layer.
This patch deals with the code that checks if there are still
pending packets for an RA / TID.

Subject: [PATCH 1520/1958] iwlwifi: tid_data logic move to upper layer -
 seq_number

The tid_data is not related to the transport layer, so move
the logic that depends on it to the upper layer.
This patch deals with the seq_number.

 queues

If the agg SM is in IWL_EMPTYING_HW_QUEUE_ADDBA or in
IWL_EMPTYING_HW_QUEUE_DELBA, we are not supposed to get Tx packets
from mac80211. mac80211 is supposed to buffer these packets for us.
A few issues have been identified in this mechanism, not all of them
were fixed.

These are unused, so can be removed safely. They also
don't make a lot of sense in Bluetooth configuration.

Subject: [PATCH 1531/1958] iwlwifi: add IO function for continuous write of
 target memory

Add new IO function _iwl_write_targ_mem_words() to support
target memory write for a continuous area. It will return
error code -EBUSY if iwl_grab_nic_access() fails to indicate
the memory write does not be performed. Meanwhile the existing
function iwl_write_targ_mem() also been updated by using
_iwl_write_targ_mem_words() in a single word case.

Subject: [PATCH 1532/1958] iwlagn: remove iwlagn_build_addsta_hcmd

This function is not needed:
 * we already have the "cmd" input to it in the
   same type (and on the stack elsewhere)
 * the "legacy_reserved" parameter is never set,
   so will always be zero

Remove the function and the stack copy of the
input command.

This is still left from when iwlegacy was part
of the driver -- then we needed a translation
for the command for 3945.

Subject: [PATCH 1534/1958] sock_diag: Fix module netlink aliases

I've made a mistake when fixing the sock_/inet_diag aliases :(

1. The sock_diag layer should request the family-based alias,
   not just the IPPROTO_IP one;
2. The inet_diag layer should request for AF_INET+protocol alias,
   not just the protocol one.

Thus fix this.

From f65c1b534b99aef1809b893387b295963821549f Mon Sep 17 00:00:00 2001

Date: Thu, 15 Dec 2011 02:43:44 +0000
Subject: [PATCH 1535/1958] sock_diag: Generalize requests cookies managements

The sk address is used as a cookie between dump/get_exact calls.
It will be required for unix socket sdumping, so move it from
inet_diag to sock_diag.

Subject: [PATCH 1539/1958] unix_diag: Dumping exact socket core

The socket inode is used as a key for lookup. This is effectively
the only really unique ID of a unix socket, but using this for
search currently has one problem -- it is O(number of sockets) :(

Does it worth fixing this lookup or inventing some other ID for
unix sockets?

Subject: [PATCH 1541/1958] unix_diag: Unix inode info NLA

Actually, the socket path if it's not anonymous doesn't give
a clue to which file the socket is bound to. Even if the path
is absolute, it can be unlinked and then new socket can be
bound to it.

With this NLA it's possible to check which file a particular
socket is really bound to.

Subject: [PATCH 1543/1958] unix_diag: Pending connections IDs NLA

When establishing a unix connection on stream sockets the
server end receives an skb with socket in its receive queue.

Report who is waiting for these ends to be accepted for
listening sockets via NLA.

There's a lokcing issue with this -- the unix sk state lock is
required to access the peer, and it is taken under the listening
sk's queue lock. Strictly speaking the queue lock should be taken
inside the state lock, but since in this case these two sockets
are different it shouldn't lead to deadlock.

before calling get_rxfh_indir or set_rxfh_indir.  Use get_rxnfc to get
the number of RX rings, and validate the contents of the new
indirection table before calling set_rxfh_indir.  Remove this
validation from drivers.

From 278bc4296bd64ffd1d3913b487dc8a520e423a7a Mon Sep 17 00:00:00 2001
From: Ben Hutchings <bhutchings@solarflare.com>
Date: Thu, 15 Dec 2011 13:56:49 +0000
Subject: [PATCH 1548/1958] ethtool: Define and apply a default policy for RX
 flow hash indirection

All drivers that support modification of the RX flow hash indirection
table initialise it in the same way: RX rings are assigned to table
entries in rotation.  Make that default policy explicit by having them
call a ethtool_rxfh_indir_default() function.

In the ethtool core, add support for a zero size value for
ETHTOOL_SRXFHINDIR, which resets the table to this default.

Partly-suggested-by: Matt Carlson <mcarlson@broadcom.com>

I didn't resolve the merge properly during the last pull of the net

The code in the final resolution should set flags to TT_CLIENT_ROAM
not TT_CLIENT_PENDING.

avoid calling the initialization functions of protocols directly,

Convert proto_list_lock into a mutex, so we can sleep and do the
necessary allocations. This lock is seldom taken, so there shouldn't
be any performance penalties associated with that

Subject: [PATCH 1559/1958] sch_gred: prefer GFP_KERNEL allocations

In control path, its better to use GFP_KERNEL allocations where
possible.

Before taking qdisc spinlock, we preallocate memory just in case we'll
need it in gred_change_vq()

This is a followup to commit 3f1e6d3fd37b (sch_gred: should not use
GFP_KERNEL while holding a spinlock)

Subject: [PATCH 1568/1958] netfilter: nf_conntrack: use atomic64 for
 accounting counters

We can use atomic64_t infrastructure to avoid taking a spinlock in fast
path, and remove inaccuracies while reading values in
ctnetlink_dump_counters() and connbytes_mt() on 32bit arches.

Suggested by Pablo.

Subject: [PATCH 1569/1958] netfilter: ctnetlink: use expect instead of master
 tuple in get operation

Use the expect tuple (if possible) instead of the master tuple for
the get operation. If two or more expectations come from the same
master, the returned expectation may not be the one that user-space
is requesting.

This is how it works for the expect deletion operation.

Although I think that nobody has been seriously using this. We
accept both possibilities, using the expect tuple if possible.
I decided to do it like this to avoid breaking backward
compatibility.

Subject: [PATCH 1571/1958] Bluetooth: Process recv path in a workqueue instead

Run recv process in workqueue helps a lot with our processing as the recv
path will also be in the process context, i.e., now all our tx and rx are
in process context.

Subject: [PATCH 1572/1958] Bluetooth: Replace spin_lock by mutex in hci_dev

Now we run everything in HCI in process context, so it's a better idea use
mutex instead spin_lock. The macro remains hci_dev_lock() (and I got rid
of hci_dev_lock_bh()), of course.

Subject: [PATCH 1573/1958] Bluetooth: Use delayed_work for connection timeout

Bluetooth rx task runs now in a workqueue, so it a good approach run any
timer that share locking with process context code also in a workqueue.

We now run everything in process context, so the mutex lock is the best
option. But in some places we still need the bh_lock_sock()

Subject: [PATCH 1583/1958] Bluetooth: Don't disable tasklets to call
 hdev->notify()

It's pointless, we aren't protecting anything since btusb_notify()
schedules a work to run, then all it operation happens without protection.
If protection is really needed here, we will fix it further.

Subject: [PATCH 1587/1958] Bluetooth: invert locking order in connect path

This move some checking code that was in l2cap_sock_connect() to
l2cap_chan_connect(). Thus we can invert the lock calls, i.e., call
lock_sock() before hci_dev_lock() to avoid a deadlock scenario.

Update hdev workqueue API usage to use the new interface, this new
interface also allow us to mark this workqueue as WQ_HIGHPRI, so now rx
and tx work gets higher priority when running.

Subject: [PATCH 1595/1958] Bluetooth: Move mgmt_set_fast_connectable to the
 right location

Fast connectable is logically after the connectable property so that's
where it should show up in the code as well (it's also after connectable
in the settings bitfield).

Subject: [PATCH 1596/1958] Bluetooth: Remove mgmt_set_service_cache

Instead of having an explicit service cache command we can make the mgmt
API simpler by implicitly enabling the cache when mgmt_read_info is
called for the first time and disabling it when mgmt_set_dev_class is
called.

Subject: [PATCH 1597/1958] Bluetooth: Move EIR and CoD update functions to a
 better position

Due to the upcoming addition of a service cache timer the functions to
update the EIR and CoD need to be higher up in mgmt.c in order to avoid
unnecessary forward-declarations. This patch simply moves code around
without any other changes in order to make subsequent patches more
readable.

Subject: [PATCH 1598/1958] Bluetooth: Add timer for automatically disabling
 the service cache

We do not want the service cache to be enabled indefinitely after
mgmt_read_info is called. To solve this a timer is added which will
automatically disable the cache if mgmt_set_dev_class isn't called
within 5 seconds of calling mgmt_read_info.

Subject: [PATCH 1603/1958] Bluetooth: Incoming ACL packets do not force active
 mode

Incoming sk_buffs always have bt_cb(skb)->force_active set to 0, so
it's misleading to use that value from the control block when calling
hci_conn_enter_active_mode() for incoming data. The destination socket
is not known in the HCI layer, so the force_active setting for each
socket isn't known either. Hard-coding the force_active parameter does
not change any behavior, but makes it obvious that incoming ACL data
never exits sniff mode.

This patch adds a missing confirm_name field to mgmt_ev_device_found.
Support for setting the correct value for this field is not implemented
yet, but having it part of the struct definition ensures that user-space
gets correct sized device_found events and is thereby able to do at
least rudimentary parsing of them.

Subject: [PATCH 1607/1958] mac80211: split addba retries in time

  Currently code allows three (HT_AGG_MAX_RETRIES) unanswered addba
requests. When this limit is reached aggregation is turned off for
given TID permanently. This doesn't seem right: three requests is
not that much, some 'blackout' can happen, but effect of it affects
whole connection indefinitely.
  This patch increases number of retries to 15. Also, when there have
been 3 or more retries it splits further retries apart by 15 seconds
instead of sending them in very short period of time.

Add ATH_DBG_ to macros to shorten the uses and
reduce the line count.

Coalesce ath_dbg formats.
Add missing spaces to coalesced formats.
Add missing newline terminations to ath_dbg formats.
Align ath_dbg arguments where appropriate.
Standardize ath_dbg formats without periods.

From 186630c2809bc87fba6e49896fa2279c43f512d2 Mon Sep 17 00:00:00 2001
From: Amitkumar Karwar <akarwar@marvell.com>
Date: Thu, 15 Dec 2011 21:00:37 -0800
Subject: [PATCH 1610/1958] mwifiex: cleanup work in scan.c

Scan type derived from IEEE80211_CHAN_PASSIVE_SCAN bit is a boolean
flag representing passive scanning. We should not again compare it
with driver specific macro MWIFIEX_SCAN_TYPE_PASSIVE to determine
passive or active scan. We can also avoid the use of local variable
by using the flag directly.

Subject: [PATCH 1612/1958] mac80211: handle SMPS action frames

When a peer changes SMPS state we should update
rate control so it doesn't have to detect it by
itself. It can't detect "dynamic" mode anyway
since that just requires rts-cts handshaking.

Subject: [PATCH 1613/1958] b43: avoid packet losses in the dma worker code.

Following Rafal request, we verified that on "modern" CPUs using one
or more workers is equivalent. Here is patch V3 that addresses the
packet loss bug in the dma engine using only one worker.

-------

This patch addresses a bug in the dma worker code that keeps draining
packets even when the hardware queues are full. In such cases packets
can not be passed down to the device and are erroneusly dropped by the
code.

This problem was already discussed here

http://www.mail-archive.com/b43-dev@lists.infradead.org/msg01413.html

and acknowledged by Michael.

Number of hardware queues is now defined in b43.h (B43_QOS_QUEUE_NUM).

Subject: [PATCH 1617/1958] brcm80211: fmac: remove oneline proto block
 functions

brcmf_os_proto_block and brcmf_os_proto_unblock are oneline
functions handling proto_block mutex. Place the mutex interface
call inline to increase readability.

Subject: [PATCH 1618/1958] brcm80211: fmac: register a dummy irq handler for
 SDIO function 2

When there is data available in dongle for driver to fetch, an
interrupt will be triggered and both SDIO function 1 and 2 will be
flagged by default in bcm4329. These two interrupt flags are
identical and only need to be handled once. Since there is no way
to turn off one flag from the dongle side, a dummy handler for
function 2 interrupt is placed.

Subject: [PATCH 1630/1958] brcm80211: fmac: remove duplicate statistics from
 driver data structure

Some dongle statistics are stored in two places and synced when net
device status inquired. There is no need to do it this way any more.
Direct all usage to dongle stats structure in order to increase
readability.

Subject: [PATCH 1631/1958] brcm80211: fmac: move dongle statistics to struct
 brcmf_bus

Dongle statistics are shared data between common layer and bus
layer. This patch places them in bus interface structure brcmf_bus
as part of the fullmac bus interface refactoring.

txoff is the flow control flag for transmit used in sdio layer.
Move it to bus layer data structure brcmf_sdio. Also flag
management code is moved out of brcmf_txflowcontrol(). This is
part of the fullmac bus interface refactoring.

Subject: [PATCH 1634/1958] brcm80211: fmac: stop referencing brcmf_pub in bus

brcmf_pub is the data structure for common layer. Since brcmf_bus
should be the only structure shared by common layer and bus layer,
stop referencing brcmf_pub from bus layer. This patch is part of
the fullmac bus interface refactoring.

Subject: [PATCH 1636/1958] brcm80211: fmac: move sdio related macros to
 sdio_host.h

dhd_bus.h will be used as the shared header file for common layer
and bus layer. It should not contain any sdio specific macros.
This patch moves them to sdio_host.h as part of the fullmac bus
interface refactoring.

Subject: [PATCH 1638/1958] brcm80211: fmac: move common layer bus interface
 context to dhd_bus.h

dhd_bus.h is the header file for bus interface. Move functions
declarations and brcmf_bus structure to there. This is part of
the fullmac bus interface refactoring.

Subject: [PATCH 1646/1958] rtlwifi: Fix locking problem introduces with commit
 6539306b

When I tested commit 6539306, I did not notice that loading an out-of-tree
module turns off lockdep testing in kernel 3.2. For that reason, I missed
the kernel WARNING shown below:

The solution fixes the warning by partially reverting commit 6539306.

Subject: [PATCH 1655/1958] ath9k_hw: make bluetooth coexistence support
 optional at compile time

Many systems (e.g. embedded systems) do not have wifi modules connected to
bluetooth modules, so bluetooth coexistence is irrelevant there. With the
addition of MCI support, ath9k picked up quite a bit of extra code that
can be compiled out this way.

This patch redefines ATH9K_HW_CAP_MCI and adds an inline wrapper for
querying the bluetooth coexistence scheme, allowing the compiler to
eliminate code that uses it, with only very little use of #ifdef.

On MIPS this reduces the total size for the modules by about 20k.

Subject: [PATCH 1656/1958] ath9k: fix tx locking issues

The commit "ath9k: simplify tx locking" introduced a soft lockup triggered
by mac80211 sending a BAR frame triggered by a driver call to
ieee80211_tx_send_bar or ieee80211_tx_status.
Fix these issues by queueing processed tx status skbs and submitting them
to mac80211 outside of the lock.

Subject: [PATCH 1657/1958] mlx4: capability for link sensing

For ConnectX3 devices, we allow link sensing only if FW explicitly
reported it supports the feature.
For older versions (ConnectX1 and 2), if the card supports both link layer types
(Ethenet and Infiniband), link sensing is supported.

Subject: [PATCH 1658/1958] mlx4_core: Changing link sensing logic

New FW can give clues to driver regarding default port type
and whether or not we should default to link sensing on the port.

2 bits are added to QUERY_PORT command:
1. suggested_type: This bit gives a hint whether the default port type should be
   IB or Ethernet.
   The driver will use this hint in case the user didn't specify explicitly the link layer
   type he wants to set.
2. default_sense: If this bit is set, we would sense the port type on start-up
   and default the port to link sensing

Subject: [PATCH 1662/1958] Revert "net: Remove unused neighbour layer ops."

This reverts commit 5c3ddec73d01a1fae9409c197078cb02c42238c3.

S390 qeth driver actually still uses the setup ops.

Subject: [PATCH 1663/1958] mac80211: Fixing sparse warning at sta_info.c

The commit 42624d4913a00219a8fdbb4bafd634d1d843be85
created following sparse warning
>net/mac80211/sta_info.c:965:24: warning: incorrect type in assignment (different address spaces)
>net/mac80211/sta_info.c:965:24:    expected struct tid_ampdu_tx *tid_tx
>net/mac80211/sta_info.c:965:24:    got struct tid_ampdu_tx [noderef] <asn:4>*<noident>

Making use of rcu_dereference_protected to fix the problem.

V2:
 - Replacing rcu_dereference with rcu_dereference_protected
   as suggested by Johannes.
 - Adding mutex_lock/unlock to satisfy the condition at
   rcu_dereference_protected

Subject: [PATCH 1665/1958] be2net: Fix INTx processing for Lancer

Lancer does not have HW registers to indicate the EQ causing the INTx
interrupt. As a result EQE entries of one EQ may be consumed when interrupt
is caused by another EQ. Fix this by arming CQs at the end of NAPI poll
routine to regenerate the EQEs.

Subject: [PATCH 1666/1958] bnx2: Update driver to use new mips firmware.

bnx2-mips-06-6.2.3 and bnx2-mips-09-6.2.1.b

New firmware fixes iSCSI problems with some LeftHand targets that don't
set TTT=0xffffffff for Data-In according to spec.  Firmware generates
exception warnings for this condition and becomes very slow.  This is
fixed by suppressing these warnings when using default error mask.

Subject: [PATCH 1667/1958] tg3: Make the RSS indir tbl admin configurable

This patch adds the ethtool callbacks necessary to change the rss
indirection table from userspace.  Should the number of interrupts
change (e.g.  across a close / open call, or through a reset) and
any one of the indirection table values fall out-of-range, the driver
will reset the indirection table to a default layout.

[Integrated many suggestions made by Ben Hutchings.]

Changes since v3

* Removed TG3_FLAG_SUPPORT_MSIX checks at the start of
  tg3_get_rxfh_indir() and tg3_set_rxfh_indir().

Subject: [PATCH 1672/1958] iwlagn: add IRQ tracing

The legacy IRQs could be read from a trace by their
IO accesses, but reading the ICT doesn't leave any
trace (pun intended ;-) ) so in order to see what
input they get we need to add specific tracepoints.

While at it, fix whitespace in two related places.

Subject: [PATCH 1673/1958] iwlagn: finer-grained HT disable

At least while debugging, a lot of people use
11n_disable=1 to disable HT completely. To be
able to figure out what parts of HT cause the
problems we see, make the parameter a bitmap,
allowing to disable all of HT and aggregation
(TX/RX) separately.

Subject: [PATCH 1678/1958] iwlwifi: Execute runtime calibration always

Runtime DC calibration was previously conditional. Remove this
behaviour, as new devices support runtime DC calibration,
while older devices ignore the runtime DC calibration request.

This patch addresses low TX throughput issues seen with the 6205.

Subject: [PATCH 1679/1958] net: fix assignment of 0/1 to bool variables.

DaveM said:
   Please, this kind of stuff rots forever and not using bool properly
   drives me crazy.

Joe Perches <joe@perches.com> gave me the spatch script:

	@@
	bool b;
	@@
	-b = 0
	+b = false
	@@
	bool b;
	@@
	-b = 1
	+b = true

I merely installed coccinelle, read the documentation and took credit.

From eb93992207dadb946a3b5cf4544957dc924a6f58 Mon Sep 17 00:00:00 2001
From: Rusty Russell <rusty@rustcorp.com.au>
Date: Mon, 19 Dec 2011 14:08:01 +0000
Subject: [PATCH 1680/1958] module_param: make bool parameters really bool (net
 & drivers/net)

module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.

(Thanks to Joe Perches for suggesting coccinelle for 0/1 -> true/false).

Subject: [PATCH 1682/1958] mlx4_en: FIX: Setting default_qpn before using it

When UDP RSS is enabled, we use same QPN for TCP and UDP ranges
The bug is that the default_qpn was used base UDP qpn before it
was set.
Fixes bug introduced in commit: 1202d460b1df3a77fda66f4ba5f90ae3527dd42f

af_iucv differs unnecessarily between state IUCV_SEVERED and
IUCV_DISCONN. This patch removes state IUCV_SEVERED.
While simplifying af_iucv, this patch removes the 2nd invocation of
cpcmd as well.

Subject: [PATCH 1693/1958] qeth: suspicious rcu_dereference_check in recovery

qeth layer3 recovery invokes its set_multicast_list function, which
invokes function __vlan_find_dev_deep requiring rcu_read_lock or
rtnl lock. This causes kernel messages:

The patch makes sure the rtnl lock is held once qeth recovery invokes
its set_multicast_list function.

Subject: [PATCH 1695/1958] netiucv: allow multiple interfaces to same peer

The NETIUCV device driver allows to connect a Linux guest on z/VM to
another z/VM guest based on the z/VM communication facility IUCV.
Multiple output paths to different guests are possible, as well as
multiple input paths from different guests.
With this feature, you can configure multiple point-to-point NETIUCV
interfaces between your Linux on System z instance and another z/VM
guest.

Subject: [PATCH 1696/1958] qeth: improve recovery during resource shortage

In case there are no system resources to run a recovery we have to clear
recovery bitmasks so a further automatic or manual driven recovery can
fix up the device.

If recovery is triggered in presence of pending asynchronous
deliveries of storage blocks we do a forced cleanup after
the corresponding tasklets are completely stopped and trigger
appropriate notifications for the correspondingerror state.

Subject: [PATCH 1700/1958] Bluetooth: Rename info_work to info_timer

It makes more sense this way, since info_timer is a timer using delayed
work API.

Subject: [PATCH 1706/1958] wl12xx: fix checking of started dev role

dev_role_id only indicates whether the dev role
is enabled, not started (e.g. on IBSS merge,
the device role is enabled, but not started).

Checking for any role in ROC (in order to determine
whether dev role was started) is wrong as well,
especially in multi-vif env.

Check for started dev role only by checking the dev_hlid.

Until we'll have a method to get the actual vif from

Subject: [PATCH 1710/1958] wl12xx: fix sched scan of DFS channels

DFS channels weren't scanned properly because
min/max_duration weren't set for these channels
even though they're required by the FW.
The change sets passive_duration and min/max_duration
for all channels as the FW uses the correct parameters
according to the channel type.

Subject: [PATCH 1711/1958] wl12xx: mark no sched scan only after FW event

stop sched scan isn't an immediate operation
and we need to wait for PERIODIC_SCAN_COMPLETE_EVENT_ID
after sending a stop before changing internal state
and notifying upper layers.
Not doing this caused problems when canceling an existing sched
scan and immediately requesting to start a new one
with a different configuration as the FW was still
in the middle of the previous sched scan.

usb_fill_int_urb() function that handles it correctly. So we just
call this function to fill in the RX URB.

Subject: [PATCH 1713/1958] Bluetooth: Remove global mutex hci_task_lock

The hci_task_lock mutex (previously a lock) was supposed to protect the
register/unregister of HCI protocols against RX/TX tasks. This will not
be needed anymore because SCO and L2CAP will always be compiled.

Moreover, with the recent move of RX/TX to workqueues per device the
global hci_task_lock was causing starvation between different HCI
devices.

Subject: [PATCH 1717/1958] libertas: clean up scan thread handling

The libertas scan thread expects priv->scan_req to be non-NULL.  In theory,
it should always be set.  In practice, we've seen the following oops:

[ 8363.163334] Process kworker/u:1 (pid: 25, stack limit = 0xee66a2f8)

While I've not found a smoking gun, there are two places that raised red flags
for me.  The first is in _internal_start_scan, when we queue up a scan; we
first queue the worker, and then set priv->scan_req.  There's theoretically
a 50mS delay which should be plenty, but doing things that way just seems
racy (and not in the good way).

The second is in the scan worker thread itself.  Depending on the state of
priv->scan_channel, we cancel pending scan runs and then requeue a run in
300mS.  We then send the scan command down to the hardware, sleep, and if
we get scan results for all the desired channels, we set priv->scan_req to
NULL.  However, it that's happened in less than 300mS, what happens with
the pending scan run?

This patch addresses both of those concerns.  With the patch applied, we
have not seen the oops in the past two weeks.

Subject: [PATCH 1719/1958] iwlagn: fix (remove) use of PAGE_SIZE

The ICT code erroneously uses PAGE_SIZE. The bug
is that PAGE_SIZE isn't necessarily 4096, so on
such platforms this code will not work correctly
as we'll try to attempt to read an index in the
table that the device never wrote, it always has
4096-byte pages.

Additionally, the manual alignment code here is
unnecessary -- Documentation/DMA-API-HOWTO.txt
states:
  The cpu return address and the DMA bus master address are both
  guaranteed to be aligned to the smallest PAGE_SIZE order which
  is greater than or equal to the requested size.  This invariant
  exists (for example) to guarantee that if you allocate a chunk
  which is smaller than or equal to 64 kilobytes, the extent of the
  buffer you receive will not cross a 64K boundary.

Just use appropriate new constants and get rid of
the alignment code.

Subject: [PATCH 1720/1958] ath9k: fix roadkill due to Joe's patch on ath_dbg()
 changes

Joe changed ath_dbg() to simpify code but while his patch was
being merged dfs.c was born and as such did not get the change
Joe envisioned. This fixes that. Test compiled with:

 make allmodconfig

When stack calls ampdu_action with action = IEEE80211_AMPDU_TX_STOP
for a stream that has already been removed from the driver, call
ieee80211_tx_ba_stop_irqsafe to clear the stream in the stack.

Subject: [PATCH 1722/1958] mac80211: ibss should not purge clients it is not
 responsible for

The IBSS merge code calls ieee80211_sta_expire() with a relatively
short expire timeout that purges other clients prematurely. The
expire function has to check that only the clients belonging to
the vif in question are purged.

Also, rename 'adapter->chan_offset' to 'adapter->sec_chan_offset'
for consistency.

Subject: [PATCH 1726/1958] mwifiex: fix issues in band configuration code

Currently due to following issues in the code even if device is
configured in B only, G only or BG mode using iw bitrates command,
ibss is getting created in BGN mode.

1) mwifiex_channels_to_cfg80211_channel_type() routine gives channel
type as NL80211_CHAN_HT20 for non-HT channel as well, because driver
doesn't store HT information provided by stack for the channel.
This issue is fixed by maintaining channel type information in
'adapter->channel_type'.
2) Band configuration is unnecessarily overwritten with BGN/AN while
setting channel.

This patch makes sure that "adapter->config_bands" correctly gets
modified while setting channel.

Subject: [PATCH 1727/1958] mac80211: Keep skb->piority for relayed frames in
 AP mode

When mac80211 relays a frame from STA1 to STA2 in AP mode it will get
re-classified in the tx path. Unfortunately the frame protocol field
is always set to ETH_P_8023 while the classification only kicks in
for ETH_P_IP. Hence, a high priority frame from STA1 will be send to
STA2 as best effort.

Instead of running classification on the frame just use the same
priority as STA1 did. Do this by adding 256 to the skb->priority
to allow cfg80211_classify8021d to shortcut frame classification.

Subject: [PATCH 1729/1958] sch_sfq: rehash queues in perturb timer

A known Out Of Order (OOO) problem hurts SFQ when timer changes
perturbation value, since all new packets delivered to SFQ enqueue might
end on different slots than previous in-flight packets.

With round robin delivery, we can thus deliver packets in a different
order.

Since SFQ is limited to small amount of in-flight packets, we can rehash
packets so that this OOO problem is fixed.

This rehashing is performed only if internal flow classifier is in use.

We now store in skb->cb[] the "struct flow_keys" so that we dont call
skb_flow_dissect() again while rehashing.

From bfab27a146ed4d722c6d399f844f955f29cd2b81 Mon Sep 17 00:00:00 2001
From: Giuseppe CAVALLARO <peppe.cavallaro@st.com>
Date: Wed, 21 Dec 2011 03:58:19 +0000
Subject: [PATCH 1730/1958] stmmac: add the experimental PCI support

This patch adds the PCI support (as EXPERIMENTAL)
this has been also tested on XLINX XC2V3000 FF1152AMT0221
D1215994A VIRTEX FPGA board.
To support the PCI bus the main part has been reworked
and both the platform and the PCI specific parts have
been moved into different files.

No local_bh_disable is needed there once we run everything in process
context. The same goes for the replacement of bh_lock_sock() by
lock_sock().

Subject: [PATCH 1736/1958] Bluetooth: Fix deadlocks with sock lock and L2CAP
 timers locks

When cancelling a delayed work (timer) in L2CAP we can not sleep holding
the sock mutex otherwise we might deadlock with an L2CAP timer handler.
This is possible because RX/TX and L2CAP timers run in different workqueues.
The scenario below illustrates the problem. Thus we are now avoiding to
sleep on the timers locks.

 ======================================================
 [ INFO: possible circular locking dependency detected ]
 3.1.0-05270-ga978dc7-dirty #239
 -------------------------------------------------------

  (sk_lock-AF_BLUETOOTH-BTPROTO_L2CAP){+.+...}, at: [<ffffffffa002ceac>] l2cap_chan_timeout+0x3c/0xe0 [bluetooth]

 but task is already holding lock:
  ((&(&chan->chan_timer)->work)){+.+...}, at: [<ffffffff81051a86>] process_one_work+0x126/0x450

 which lock already depends on the new lock.

 the existing dependency chain (in reverse order) is:

Subject: [PATCH 1737/1958] Bluetooth: Add MITM mechanism to LE-SMP

To achive Man-In-The-Middle (MITM) level security with Low Energy,
we have to enable User Passkey Comparison.  This commit modifies the
hard-coded JUST-WORKS pairing mechanism to support query via the MGMT
interface of Passkey comparison and User Confirmation.

Subject: [PATCH 1745/1958] Partial revert "Basic kernel memory functionality
 for the Memory Controller"

This reverts commit e5671dfae59b165e2adfd4dfbdeab11ac8db5bda.

After a follow up discussion with Michal, it was agreed it would
be better to leave the kmem controller with just the tcp files,
deferring the behavior of the other general memory.kmem.* files
for a later time, when more caches are controlled. This is because
generic kmem files are not used by tcp accounting and it is
not clear how other slab caches would fit into the scheme.

We are reverting the original commit so we can track the reference.
Part of the patch is kept, because it was used by the later tcp
code. Conflicts are shown in the bottom. init/Kconfig is removed from
the revert entirely.

Subject: [PATCH 1747/1958] netlink: wake up netlink listeners sooner (v2)

This patch changes it to yield sooner at halfway instead. Still not a cure-all
for listener overrun if listner is slow, but works much reliably.

Subject: [PATCH 1748/1958] netfilter: rework user-space expectation helper
 support

This partially reworks bc01befdcf3e40979eb518085a075cbf0aacede0
which added userspace expectation support.

This patch removes the nf_ct_userspace_expect_list since now we
force to use the new iptables CT target feature to add the helper
extension for conntracks that have attached expectations from
userspace.

A new version of the proof-of-concept code to implement userspace
helpers from userspace is available at:

http://people.netfilter.org/pablo/userspace-conntrack-helpers/nf-ftp-helper-POC.tar.bz2

This patch also modifies the CT target to allow to set the
conntrack's userspace helper status flags. This flag is used
to tell the conntrack system to explicitly allocate the helper
extension.

This helper extension is useful to link the userspace expectations
with the master conntrack that is being tracked from one userspace
helper.

This feature fixes a problem in the current approach of the
userspace helper support. Basically, if the master conntrack that
has got a userspace expectation vanishes, the expectations point to
one invalid memory address. Thus, triggering an oops in the
expectation deletion event path.

I decided not to add a new revision of the CT target because
I only needed to add a new flag for it. I'll document in this
issue in the iptables manpage. I have also changed the return
value from EINVAL to EOPNOTSUPP if one flag not supported is
specified. Thus, in the future adding new features that only
require a new flag can be added without a new revision.

There is no official code using this in userspace (apart from
the proof-of-concept) that uses this infrastructure but there
will be some by beginning 2012.

From cbc9f2f4fcd70d5a627558ca9a881fa9391abf69 Mon Sep 17 00:00:00 2001
From: Patrick McHardy <kaber@trash.net>
Date: Fri, 23 Dec 2011 13:59:49 +0100
Subject: [PATCH 1749/1958] netfilter: nf_nat: export NAT definitions to
 userspace

Export the NAT definitions to userspace. So far userspace (specifically,
iptables) has been copying the headers files from include/net. Also
rename some structures and definitions in preparation for IPv6 NAT.
Since these have never been officially exported, this doesn't affect
existing userspace code.

Subject: [PATCH 1752/1958] netfilter: nat: remove module reference counting
 from NAT protocols

The only remaining user of NAT protocol module reference counting is NAT
ctnetlink support. Since this is a fairly short sequence of code, convert
over to use RCU and remove module reference counting.

Module unregistration is already protected by RCU using synchronize_rcu(),
so no further changes are necessary.

Subject: [PATCH 1753/1958] netfilter: nf_nat: remove obsolete code from
 nf_nat_icmp_reply_translation()

The inner tuple that is extracted from the packet is unused. The code also
doesn't have any useful side-effects like verifying the packet does contain
enough data to extract the inner tuple since conntrack already does the
same, so remove it.

Subject: [PATCH 1754/1958] netfilter: nf_nat: remove obsolete check in
 nf_nat_mangle_udp_packet()

The packet size check originates from a time when UDP helpers could
accidentally mangle incorrect packets (NEWNAT) and is unnecessary
nowadays since the conntrack helpers invoke the NAT helpers for the
proper packet directly.

Subject: [PATCH 1755/1958] netfilter: ctnetlink: remove dead NAT code

The NAT range to nlattr conversation callbacks and helpers are entirely
dead code and are also useless since there are no NAT ranges in conntrack
context, they are only used for initially selecting a tuple. The final NAT
information is contained in the selected tuples of the conntrack entry.

From 7afc5dbde09104b023ce04465ba71aaba0fc4346 Mon Sep 17 00:00:00 2001
From: Krishna Gudipati <kgudipat@brocade.com>
Date: Thu, 22 Dec 2011 13:30:19 +0000
Subject: [PATCH 1759/1958] bna: Add debugfs interface.

Change details:
	- Add debugfs support to obtain firmware trace, saved firmware trace on
	  an IOC crash, driver info and read/write to registers.

	- debugfs hierarchy:
	  bna/pci_dev:<pci_name>
	  where the pci_name corresponds to the one under /sys/bus/pci/drivers/bna

	- Following are the new debugfs entries added:
	  fwtrc: collect current firmware trace.
	  fwsave: collect last saved fw trace as a result of firmware crash.
	  regwr: write one word to chip register
	  regrd: read one or more words from chip register.
	  drvinfo: collect the driver information.

Subject: [PATCH 1765/1958] netem: loss model API sizes

The new netem loss model is configured with nested netlink messages.
This code is being overly strict about sizes, and is easily confused
by padding (or possible future expansion). Also message
for gemodel is incorrect.

We can't do this without propagating the const to nlk_sk()
too, otherwise:

Subject: [PATCH 1769/1958] netfilter: add extended accounting infrastructure
 over nfnetlink

We currently have two ways to account traffic in netfilter:

- iptables chain and rule counters:

 # iptables -L -n -v
Chain INPUT (policy DROP 3 packets, 867 bytes)
 pkts bytes target     prot opt in     out     source               destination
    8  1104 ACCEPT     all  --  lo     *       0.0.0.0/0            0.0.0.0/0

- use flow-based accounting provided by ctnetlink:

 # conntrack -L
tcp      6 431999 ESTABLISHED src=192.168.1.130 dst=212.106.219.168 sport=58152 dport=80 packets=47 bytes=7654 src=212.106.219.168 dst=192.168.1.130 sport=80 dport=58152 packets=49 bytes=66340 [ASSURED] mark=0 use=1

While trying to display real-time accounting statistics, we require
to pool the kernel periodically to obtain this information. This is
OK if the number of flows is relatively low. However, in case that
the number of flows is huge, we can spend a considerable amount of
cycles to iterate over the list of flows that have been obtained.

Moreover, if we want to obtain the sum of the flow accounting results
that match some criteria, we have to iterate over the whole list of
existing flows, look for matchings and update the counters.

This patch adds the extended accounting infrastructure for
nfnetlink which aims to allow displaying real-time traffic accounting
without the need of complicated and resource-consuming implementation
in user-space. Basically, this new infrastructure allows you to create
accounting objects. One accounting object is composed of packet and
byte counters.

In order to manipulate create accounting objects, you require the
new libnetfilter_acct library. It contains several examples of use:

libnetfilter_acct/examples# ./nfacct-add http-traffic
libnetfilter_acct/examples# ./nfacct-get
http-traffic = { pkts = 000000000000,   bytes = 000000000000 };

Then, you can use one of this accounting objects in several iptables
rules using the new nfacct match (which comes in a follow-up patch):

 # iptables -I INPUT -p tcp --sport 80 -m nfacct --nfacct-name http-traffic
 # iptables -I OUTPUT -p tcp --dport 80 -m nfacct --nfacct-name http-traffic

The idea is simple: if one packet matches the rule, the nfacct match
updates the counters.

Thanks to Patrick McHardy, Eric Dumazet, Changli Gao for reviewing and
providing feedback for this contribution.

Subject: [PATCH 1778/1958] tipc: Optimize detection of duplicate media
 registration

Streamlines the detection of an attempt to register a TIPC media structure
using an already registered name or type identifier. The revised logic now
reuses an existing routine to detect an existing name and no longer
unnecessarily manipulates the media type counter during an unsuccessful
registration attempt.

Subject: [PATCH 1779/1958] tipc: Eliminate duplication of media structures

Changes TIPC's list of registered media types from an array of media
structures to an array of pointers to media structures. This eliminates
the need to copy of the contents of the structure passed in during media
registration.

Subject: [PATCH 1780/1958] tipc: Streamline media registration error checking

Simplifies error handling performed during media registration, since
TIPC no longer supports the dynamic addition of new media types that
are potentially error-prone. These simplifications include the following:

1) No longer check for premature registration of a new media type.
2) No longer check for negative link priority values (which was pointless
   since such values are unsigned, and could cause a compiler warning).
3) No longer generate a warning describing the exact cause of any
   registration failure (just warns that overall registration failed).

Enhances conversion of a media address to printable form so that an
unconvertable address will be displayed as a string of hex digits,
rather than not being displayed at all. (Also removes a pointless check
for the existence of the media-specific address conversion routine,
since the routine is not optional.)

Subject: [PATCH 1782/1958] tipc: Add new address conversion routines for
 Ethernet media

Enhances TIPC's Ethernet media support to provide 3 new address conversion
routines, which allow TIPC to interpret an address that is in string form
and to convert an address to and from the 20 byte format used in TIPC's
neighbor discovery messages.

These routines are pre-requisites to a follow on commit that hides all
media-specific addressing details from TIPC's generic bearer code.

Subject: [PATCH 1783/1958] tipc: Hide media-specific addressing details from
 generic bearer code

Reworks TIPC's media address data structure and associated processing
routines to transfer all media-specific details of address conversion
to the associated TIPC media adaptation code. TIPC's generic bearer code
now only needs to know which media type an address is associated with
and whether or not it is a broadcast address, and totally ignores the
"value" field that contains the actual media-specific addressing info.

These changes eliminate the need for a number of endianness conversion
operations and will make it easier for TIPC to support new media types
in the future.

Subject: [PATCH 1784/1958] tipc: Ignore neighbor discovery messages containing
 invalid address

Adds a check to ensure that TIPC ignores an incoming neighbor discovery
message that specifies an invalid media address as its source. The check
ensures that the source address is a valid, non-broadcast address that
could legally be used by a neighboring link endpoint.

Subject: [PATCH 1785/1958] tipc: Allow run-time alteration of default link
 settings

Permits run-time alteration of default link settings on a per-media
and per-bearer basis, in addition to the existing per-link basis.
The following syntax can now be used:

    tipc-config -lt=<link-name|bearer-name|media-name>/<tolerance>
    tipc-config -lp=<link-name|bearer-name|media-name>/<priority>
    tipc-config -lw=<link-name|bearer-name|media-name>/<window>

Note that changes to the default settings for a given media type has
no effect on the default settings used by existing bearers. Similarly,
changes to default bearer settings has no effect on existing link
endpoints that utilize that interface.

Thanks to Florian Westphal <fw@strlen.de> for his contributions to
the development of this enhancement.

Change TIPC's shutdown code to deactivate generic networking support
before terminating Ethernet media support. The deactivation of generic
networking support causes all existing bearers to be destroyed, meaning
the Ethernet media termination routine no longer has to bother marking
them as unavailable.

Subject: [PATCH 1788/1958] tipc: Do timely cleanup of disabled Ethernet bearer
 resources

Modifies Ethernet bearer disable logic to break the association between
the bearer and its device driver at the time the bearer is disabled,
rather than when the TIPC module is unloaded. This allows the array
entry used by the disabled bearer to be re-used if the same bearer (or
a different one) is subsequently enabled.

Gets rid of two pointless operations that zero out the array used to

initialize the array on start up since it is a global variable that is
already zero'd out, and there is no need to zero it out on exit because
the array is never referenced again.

Subject: [PATCH 1792/1958] tipc: Eliminate dynamic allocation of broadcast
 link data structures

Creates global variables to hold the broadcast link's pseudo-bearer and
pseudo-link structures, rather than allocating them dynamically. There
is only a single instance of each structure, and changing over to static
allocation allows elimination of code to handle the cases where dynamic
allocation was unsuccessful.

The memset in the teardown code may look like they aren't used, but
the same teardown code is run when there is a non-fatal error at
init-time, so that stale data isn't present when the user fixes the
cause of the soft error.

Subject: [PATCH 1794/1958] tipc: Handle broadcast attempt when no neighboring
 nodes exist

Adds a check to detect when an attempt is made to send a message
via the broadcast link and no neighboring nodes are currently available
to receive it. Rather than wasting effort passing the message to the
broadcast link and broadcast bearer, who will only throw it away,
TIPC now frees the message immediately and reports success (i.e. the
message has been delivered to all available destinations).

Subject: [PATCH 1795/1958] tipc: Minor optimization of broadcast link transmit
 queue statistic

The two broadcast link statistics fields that are used to derive the
average length of that link's transmit queue are now updated only after
a successful attempt to send a broadcast message, since there is no need
to update these values when an unsuccessful send attempt leaves the
queue unchanged.

 with last node is lost

Adds code to release any unsent broadcast messages in the broadcast link
transmit queue if TIPC loses contact with its only neighboring node.
Previously, a broadcast link that was in the congested state would hold
on to the unsent messages, even though the messages were now undeliverable.

Subject: [PATCH 1797/1958] tipc: Ignore broadcast acknowledgements that are
 out-of-range

Adds checks to TIPC's broadcast link so that it ignores any
acknowledgement message containing a sequence number that does not
correspond to an unacknowledged message currently in the broadcast
link's transmit queue.

This change prevents the broadcast link from becoming stalled if a
newly booted node receives stale broadcast link acknowledgement
information from another node that has not yet fully synchronized
its end of the broadcast link to reflect the current state of the
new node's end.

Migrates the buf_seqno() helper routine from broadcast link level to
unicast link level so that it can be used both types of TIPC links.
This is a cosmetic change only, and does not affect the operation of TIPC.

Subject: [PATCH 1801/1958] net: meth: Add set_rx_mode hook to fix ICMPv6
 neighbor discovery

SGI IP32 (O2)'s ethernet driver (meth) lacks a set_rx_mode function, which
prevents IPv6 from working completely because any ICMPv6 neighbor
solicitation requests aren't picked up by the driver.  So the machine can
ping out and connect to other systems, but other systems will have a very
hard time connecting to the O2.

Subject: [PATCH 1802/1958] netfilter: xtables: move ipt_ecn to xt_ecn

Prepare the ECN match for augmentation by an IPv6 counterpart. Since
no symbol dependencies to ipv6.ko are added, having a single ecn match
module is the more so welcome.

Subject: [PATCH 1804/1958] netfilter: xtables: add an IPv6 capable version of
 the ECN match

References: http://www.spinics.net/lists/netfilter-devel/msg18875.html

Augment xt_ecn by facilities to match on IPv6 packets' DSCP/TOS field
similar to how it is already done for the IPv4 packet field.

Subject: [PATCH 1807/1958] net: fec: Adjust ENET MDIO timeouts

On extensive NFS boots on a mx6qsabrelite board it was noted that "FEC: MDIO read timeout" were occuring,
which caused failure on loading the FEC driver.

The original FEC_MII_TIMEOUT was set to 1 ms, which is too low when passed to the usecs_to_jiffies macro.

On ARM one jiffy is 10ms, so use a timeout of 30ms, which corresponds to 3 jiffies.

After running extensive NFS boots, the MDIO timeouts do not occur anymore with this change.

 ipv6_add_addr()

The route we have here is for the address being added to the interface,
ie. for input packet processing.

Therefore using that route to determine whether an output nexthop gateway
is known and resolved doesn't make any sense.

So, simply remove this test, it never triggered anyways.

Subject: [PATCH 1810/1958] ax25: avoid overflows in ax25_setsockopt()

Commit be639ac6 ("NET: AX.25: Check ioctl arguments to avoid overflows
further down the road") rejects very large arguments, but doesn't
completely fix overflows on 64-bit systems.  Consider the AX25_T2 case.

	int opt;
	...
	if (opt < 1 || opt > ULONG_MAX / HZ) {
		res = -EINVAL;
		break;
	}
	ax25->t2 = opt * HZ;

The 32-bit multiplication opt * HZ would overflow before being assigned
to 64-bit ax25->t2.  This patch changes "opt" to unsigned long.

Subject: [PATCH 1812/1958] ipv6: Use universal hash for NDISC.

In order to perform a proper universal hash on a vector of integers,
we have to use different universal hashes on each vector element.

Which means we need 4 different hash randoms for ipv6.

Subject: [PATCH 1814/1958] ipv6: Kill rt6i_dev and rt6i_expires defines.

It just obscures that the netdevice pointer and the expires value are
implemented in the dst_entry sub-object of the ipv6 route.

And it makes grepping for dst_entry member uses much harder too.

Subject: [PATCH 1818/1958] mlx4_core: limiting VF port options

At the moment VFs can only operate in Eth mode.
In addition we don't want the VF to attempt link sensing,
so we block this option as well.

Subject: [PATCH 1820/1958] virtio_net: set/cancel work on ndo_open/ndo_stop

Michael S. Tsirkin noticed that we could run the refill work after
ndo_close, which can re-enable napi - we don't disable it until
virtnet_remove.  This is clearly wrong, so move the workqueue control
to ndo_open and ndo_stop (aka. virtnet_open and virtnet_close).

One subtle point: virtnet_probe() could simply fail if it couldn't
allocate a receive buffer, but that's less polite in virtnet_open() so
we schedule a refill as we do in the normal receive path if we run out
of memory.

Subject: [PATCH 1821/1958] virtio_net: use non-reentrant workqueue.

Michael S. Tsirkin also noticed that we could run the refill work
multiple CPUs: if we kick off a refill on one CPU and then on another,
they would both manipulate the queue at the same time (they use
napi_disable to avoid racing against the receive handler itself).

Tejun points out that this is what the WQ_NON_REENTRANT flag is for,
and that there is a convenient system kthread we can use.

Subject: [PATCH 1822/1958] ipv6: Fix neigh lookup using NULL device.

In some of the rt6_bind_neighbour() call sites, it hasn't hooked
up the rt->dst.dev pointer yet, so we'd deref a NULL pointer when
obtaining dev->ifindex for the neighbour hash function computation.

Just pass the netdevice explicitly in to fix this problem.

Give it a meaningful prefix, as suggested by DaveM, so that it
is consistent with things like struct tipc_bearer, and so it isn't
confused with anything else.  This has no impact on the actual
runtime code behaviour.

Date: Thu, 29 Dec 2011 20:58:42 -0500
Subject: [PATCH 1829/1958] tipc: rename struct link* to struct tipc_link*

This converts the following:

	struct link		->	struct tipc_link
	struct link_req		->	struct tipc_link_req
	struct link_name	->	struct tipc_link_name

Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

Subject: [PATCH 1830/1958] tipc: rename struct bearer_name to struct
 tipc_bearer_names

The addition of the "s" to indicate pluralization is intentional,
since the struct actually contains two name variants.

Subject: [PATCH 1833/1958] sock_diag: Introduce the meminfo nla core (v2)

Add a routine that dumps memory-related values of a socket.
It's made as an array to make it possible to add more stuff
here later without breaking compatibility.

Since v1: The SK_MEMINFO_ constants are in userspace
visible part of sock_diag.h, the rest is under __KERNEL__.

in the same way move the respective code into helpers.

Subject: [PATCH 1837/1958] unix_diag: Fixup RQLEN extension report

While it's not too late fix the recently added RQLEN diag extension
to report rqlen and wqlen in the same way as TCP does.

I.e. for listening sockets the ack backlog length (which is the input
queue length for socket) in rqlen and the max ack backlog length in
wqlen, and what the CINQ/OUTQ ioctls do for established.

Subject: [PATCH 1838/1958] IPv6: Avoid taking write lock for
 /proc/net/ipv6_route

During some debugging I needed to look into how /proc/net/ipv6_route
operated and in my digging I found its calling fib6_clean_all() which uses
"write_lock_bh(&table->tb6_lock)" before doing the walk of the table. I
found this on 2.6.32, but reading the code I believe the same basic idea
exists currently. Looking at the rtnetlink code they are only calling
"read_lock_bh(&table->tb6_lock);" via fib6_dump_table(). While I realize
reading from proc isn't the recommended way of fetching the ipv6 route
table; taking a write lock seems unnecessary and would probably cause
network performance issues.

To verify this I loaded up the ipv6 route table and then ran iperf in 3
cases:
  * doing nothing
  * reading ipv6 route table via proc
    (while :; do cat /proc/net/ipv6_route > /dev/null; done)
  * reading ipv6 route table via rtnetlink
    (while :; do ip -6 route show table all > /dev/null; done)

* Load the ipv6 route table up with:
  * for ((i = 0;i < 4000;i++)); do ip route add unreachable 2000::$i; done

* iperf commands:
  * client: iperf -i 1 -V -c <ipv6 addr>
  * server: iperf -V -s

* iperf results - 3 runs each (in Mbits/sec)
  * nothing: client: 927,927,927 server: 927,927,927
  * proc: client: 179,97,96,113 server: 142,112,133
  * iproute: client: 928,927,928 server: 927,927,927

lock_stat shows taking the write lock is causing the slowdown. Using this
info I decided to write a version of fib6_clean_all() which replaces
write_lock_bh(&table->tb6_lock) with read_lock_bh(&table->tb6_lock). With
this new function I see the same results as with my rtnetlink iperf test.

Subject: [PATCH 1839/1958] netem: fix classful handling

Commit 10f6dfcfde (Revert "sch_netem: Remove classful functionality")
reintroduced classful functionality to netem, but broke basic netem
behavior :

netem uses an t(ime)fifo queue, and store timestamps in skb->cb[]

If qdisc is changed, time constraints are not respected and other qdisc
can destroy skb->cb[] and block netem at dequeue time.

Fix this by always using internal tfifo, and optionally attach a child
qdisc to netem (or a tree of qdiscs)

Example of use :

DEV=eth3
tc qdisc del dev $DEV root
tc qdisc add dev $DEV root handle 30: est 1sec 8sec netem delay 20ms 10ms
tc qdisc add dev $DEV handle 40:0 parent 30:0 tbf \
	burst 20480 limit 20480 mtu 1514 rate 32000bps

qdisc netem 30: root refcnt 18 limit 1000 delay 20.0ms  10.0ms
 Sent 190792 bytes 413 pkt (dropped 0, overlimits 0 requeues 0)
 rate 18416bit 3pps backlog 0b 0p requeues 0
qdisc tbf 40: parent 30: rate 256000bit burst 20Kb/8 mpu 0b lat 0us
 Sent 190792 bytes 413 pkt (dropped 6, overlimits 10 requeues 0)
 backlog 0b 5p requeues 0

Subject: [PATCH 1842/1958] be2net: query link status in be_open()

be2net gets an async link status notification from the FW when it creates
an MCC queue. There are some cases in which this gratuitous notification
is not received from FW. To cover this explicitly query the link status
in be_open().

Subject: [PATCH 1843/1958] netfilter: nfnetlink_acct: fix nfnl_acct_get
 operation

The get operation was not sending the message that was built to
user-space. This patch also includes the appropriate handling for
the return value of netlink_unicast().

Moreover, fix error codes on error (for example, for non-existing
entry was uncorrect).

Rx mode should be reset after resming, so unconditionally updating rx
mode rather than conditionally updating based on the value we
remembered, otherwise unexpected value may be used by the nic after
resuming.

btw. I find and test this when debugging guest hibernation in qemu, as
I did not have a 8139cp card in hand, this patch is untested in a

Subject: [PATCH 1853/1958] bonding: fix error handling if slave is busy (v2)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If slave device already has a receive handler registered, then the
error unwind of bonding device enslave function is broken.

The following will leave a pointer to freed memory in the slave
device list, causing a later kernel panic.
# modprobe dummy
# ip li add dummy0-1 link dummy0 type macvlan
# modprobe bonding
# echo +dummy0 >/sys/class/net/bond0/bonding/slaves

The fix is to detach the slave (which removes it from the list)
in the unwind path.

Subject: [PATCH 1856/1958] sch_sfq: dont put new flow at the end of flows

SFQ enqueue algo puts a new flow _behind_ all pre-existing flows in the
circular list. In fact this is probably an old SFQ implementation bug.

100 Mbits = ~8333 full frames per second, or ~8 frames per ms.

With 50 flows, it means your "new flow" will have to wait 50 packets
being sent before its own packet. Thats the ~6ms.

We certainly can change SFQ to give a priority advantage to new flows,
so that next dequeued packet is taken from a new flow, not an old one.

Subject: [PATCH 1859/1958] net/davinci: do not use all descriptors for tx
 packets

The driver uses a shared pool for both rx and tx descriptors.
During open it queues fixed number of 128 descriptors for receive
packets. For each received packet it tries to queue another
descriptor. If this fails the descriptor is lost for rx.
The driver has no limitation on tx descriptors to use, so it
can happen during a nmap / ping -f attack that the driver
allocates all descriptors for tx and looses all rx descriptors.
The driver stops working then.
To fix this limit the number of tx descriptors used to half of
the descriptors available, the rx path uses the other half.

Tested on a custom board using nmap / ping -f to the board from
two different hosts.

Subject: [PATCH 1862/1958] net/smsc911x: Check if PHY is in operational mode
 before software reset

SMSC LAN generation 4 chips integrate an IEEE 802.3 ethernet physical layer.
The PHY driver for this integrated chip enable an energy detect power-down mode.
When the PHY is in a power-down mode, it prevents the MAC portion chip to be
software reseted.

That means that if we compile the kernel with the configuration option SMSC_PHY
enabled and try to bring the network interface up without an cable plug-ed the
PHY will be in a low power mode and the software reset will fail returning -EIO
to user-space:

root@igep00x0:~# ifconfig eth0 up
ifconfig: SIOCSIFFLAGS: Input/output error

This patch disable the energy detect power-down mode before trying to software
reset the LAN chip and re-enables after it was reseted successfully.

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

Currently the driver only uses location values to maintain an ordered
list of filters.  Make it reject location values >= MAX_FILER_IDX
passed to the ETHTOOL_SRXCLSRLINS command, consistent with the range
it reports for the ETHTOOL_GRXCLSRLALL command.

Subject: [PATCH 1864/1958] ethtool: Allow drivers to select RX NFC rule
 locations

Define special location values for RX NFC that request the driver to
select the actual rule location.  This allows for implementation on
devices that use hash-based filter lookup, whereas currently the API is
more suited to devices with TCAM lookup or linear search.

In ethtool_set_rxnfc() and the compat wrapper ethtool_ioctl(), copy
the structure back to user-space after insertion so that the actual
location is returned.

Subject: [PATCH 1871/1958] net_sched: sfq: fix mem alloc error recovery

Since commit 817fb15dfd98 (net_sched: sfq: allow divisor to be a
parameter), we can leave perturbation timer armed if a memory allocation
error aborts sfq_init().

Memory containing active struct timer_list is freed and kernel can
crash.

Call sfq_destroy() from sfq_init() to properly dismantle qdisc.

Subject: [PATCH 1872/1958] net_sched: sfq: always randomize hash perturbation

SFQ q->perturbation is used in sfq_hash() as an input to Jenkins hash.

We currently randomize this 32bit value only if a perturbation timer is
setup.

Its much better to always initialize it to defeat attackers, or else
they can predict very well what kind of packets they have to forge to
hit a particular flow.

This seems to not serve any purpose anymore, at least all frame

let's save the expensive memmove and just leave the QoS header in the
802.11 frame for further processing.

Subject: [PATCH 1876/1958] NFC: Handle error during NCI data exchange

Add support for NCI Interface Error Notification.
When this notification is received and we're during a
data exchange transaction, indicate an error to the NFC
core layer via the data exchange callback.

    cfg80211: indent regulatory messages with spaces

    The regulatory messages in syslog look weird:

    kernel: cfg80211: Regulatory domain: US
    kernel: ^I(start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp)
    kernel: ^I(2402000 KHz - 2472000 KHz @ 40000 KHz), (600 mBi, 2700 mBm)

    kernel: ^I(5735000 KHz - 5835000 KHz @ 40000 KHz), (600 mBi, 3000 mBm)

    Indent them with four spaces instead of the tab character to get prettier
    output.

Subject: [PATCH 1883/1958] cfg80211: relicense reg.c reg.h and genregdb.awk to
 ISC
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Following the tradition we have had with ath5k, ath9k, CRDA,
wireless-regdb I'd like to license this code under the permissive ISC
license for the code sharing purposes with other OSes, it'd sure be nice
to help the landscape in this area. Although I am %82.89 owner of the
regulatory code I have asked every contributor to the regulatory code
and have receieved positive Acked-bys from everyone except two deceased
entities:

 o Frans Pop RIP 2010 [0]
	- Frans Pop <elendil@planet.nl>
	- Frans Pop <fjp@debian.org>
 o Nokia     RIP February, 11, 2011 [1], [2]
	- ext-yuri.ershov@nokia.com
	- kalle.valo@nokia.com

Frans Pop's contribution was a simple patch 55f98938, titled,
"wireless: remove trailing space in messages" which just add a \n
to some printk lines. I'm going to treat these additions as
uncopyrightable.

As for the contributions made by employees on behalf of Nokia
my contact point was Petri Karhula <petri.karhula@nokia.com> but
after one month he noted he had not been able to get traction from the
legal department on this request, as such it I proceeded by replacing
their contributions in previous patches.

The end goal is to help a clean rewrite that starts in userspace
that is shared under ISC license which currently is taking place with
the regulatory simulator [3].

Subject: [PATCH 1893/1958] b43legacy: Avoid packet losses in the dma worker
 code

This patch addresses a bug in the dma worker code that keeps draining
packets even when the hardware queues are full. In such cases packets
can not be passed down to the device and are erroneusly dropped by the
code. It is based on commit bad6919469662b7c92bc6353642aaaa777b36bac,
which fixes the same problem in b43.

Subject: [PATCH 1896/1958] wireless: Treat IPv6 diffserv the same as IPv4 for
 802.11e
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Wireless will select a different hardware queue based on the
top 3 bits of the diffserv field, for ipv4. Extend that queue
selection mechanism to ipv6, and make the calls orthogonal.

Subject: [PATCH 1897/1958] mac80211: always clear SDATA_STATE_OFFCHANNEL flag

If the vif is stopped while it is offchannel (e.g. right
after p2p negotiation) the SDATA_STATE_OFFCHANNEL flag
is never get cleared, resulting in various bad effects
(e.g. GO can't start beaconing).

Fix it by clearing the SDATA_STATE_OFFCHANNEL flag
even if the vif is stopped.

Subject: [PATCH 1899/1958] iwlegacy: off by one in
 iwl3945_hw_build_tx_cmd_rate()

We use "rate_index" like this:
	rate = iwl3945_rates[rate_index].plcp;
The iwl3945_rates[] array has IWL_RATE_COUNT_3945 elements so the
limit here is off by one.

Subject: [PATCH 1907/1958] iwlegacy: 3945: fix hw passive scan on radar

Patch fix firmware error on "iw dev wlan0 scan passive" for
hardware scanning (with disable_hw_scan=0 module parameter).

 iwl3945 0000:03:00.0: Can't stop Rx DMA.

We have disable ability to change passive scanning to active on
particular channel when traffic is detected on that channel. Otherwise
firmware will report error, when we try to do passive scan on radar
channels.

Subject: [PATCH 1908/1958] ath9k_hw: increase tx status ring buffer size

AR9003 chips read tx status from ring buffer whose max number of
status descriptor is mininal compared to max number of tx buffers.
On a stress condition, it can be easily overflown which might cause
false tx hung detection. Though increasing number of max status
descriptors consumes more memory, it helps to avoid false positive
chip resets.

Subject: [PATCH 1909/1958] net/rfkill/rfkill-gpio.c: introduce missing kfree

Error handling code following a kmalloc should free the allocated data.
The label fail_alloc already does this for rfkill.

A simplified version of the semantic match that finds the problem is as
follows: (http://coccinelle.lip6.fr)

// <smpl>

Subject: [PATCH 1910/1958] mac80211: fix scan state machine

when we run high bandwidth UDP traffic and we trigger a scan, the scan
state machine seems to be looping in SUSPEND->RESUME->DECISION->SUSPEND
and SET_CHANNEL seems to be never called as 'tx_empty' is never true
while running UDP traffic. fix this by settting SET_CHANNEL state when
we get into RESUME state.

Subject: [PATCH 1911/1958] mac80211: fix kernel panic in IBSS due to a
 regression

kernel panic occurs when we create an IBSS mode and leave it for
sometime without any joiner and this is introduced by the
commit ec2b774e7c91094d8c00de579646f1162b87b01e where we don't
put proper braces for 'list_for_each_entry_safe' and we pass an
invalid 'sta' pointer to __sta_info_destroy

Testing on the openSUSE wireless forum has shown that a Linksys
WUSB54GC v3 with USB ID 1737:0077 works with rt2800usb when the ID is
written to /sys/.../new_id. This ID can therefore be moved out of UNKNOWN.

Subject: [PATCH 1919/1958] rt2800usb: Let rt2x00usb handle USB padding

Older USB drivers does not append end padding to skb but instead report
it in size of data to be transmitted to HW. rt2800usb should follow that
behaviour. Custom write_tx_data callback which was adding pad to skb
is not be needed any more.

Thanks to this patch frames handed back from rt2800usb to mac80211 will
no longer contain end padding.

Subject: [PATCH 1920/1958] rt2x00usb: Zero USB padding before sending URB

When USB driver requires padding at the end of frame or URB it will report
this need by increasing return value of get_tx_data_len callback. Common
USB code uses that return value as desired URB length.

Ensure that appropriate part of skb's tailroom exists and is zeroed.

Subject: [PATCH 1924/1958] mac80211: Call driver commands after drv_start in
 mac80211 restart code

Ideally, hardware/firmware initialization is complete after the
drv_start routine. In mac80211 restart code (ieee80211_reconfig),
defer calling the driver commands i.e. setup fragmentation
threshold, rts threshold and coverage class till drv_start
routine is called.

Subject: [PATCH 1927/1958] ipv6: Check RA for sllao when configuring
 optimistic ipv6 address (v2)

Recently Dave noticed that a test we did in ipv6_add_addr to see if we next hop
route for the interface we're adding an addres to was wrong (see commit
7ffbcecbeed91e5874e9a1cfc4c0cbb07dac3069).  for one, it never triggers, and two,
it was completely wrong to begin with.  This test was meant to cover this
section of RFC 4429:

3.3 Modifications to RFC 2462 Stateless Address Autoconfiguration

   * (modifies section 5.5) A host MAY choose to configure a new address
        as an Optimistic Address.  A host that does not know the SLLAO
        of its router SHOULD NOT configure a new address as Optimistic.
        A router SHOULD NOT configure an Optimistic Address.

This patch should bring us into proper compliance with the above clause.  Since
we only add a SLAAC address after we've received a RA which may or may not
contain a source link layer address option, we can pass a pointer to that option
to addrconf_prefix_rcv (which may be null if the option is not present), and
only set the optimistic flag if the option was found in the RA.

Change notes:
(v2) modified the new parameter to addrconf_prefix_rcv to be a bool rather than
a pointer to make its use more clear as per request from davem.

Subject: [PATCH 1928/1958] r6040: use an unique MDIO bus name

We should use an unique MDIO bus name which does not clash with anything
else in the system like the Fixed MDIO bus. The bus is now named:
r6040-<card number> which is unique in the system.

Subject: [PATCH 1935/1958] ipv6/addrconf: speedup /proc/net/if_inet6 filling

This ensures a linear behaviour when filling /proc/net/if_inet6 thus making
ifconfig run really fast on IPv6 only addresses. In fact, with this patch and
the IPv4 one sent a while ago, ifconfig will run in linear time regardless of
address type.

IPv4 related patch: f04565ddf52e401880f8ba51de0dff8ba51c99fd
	 dev: use name hash for dev_seq_ops
	 ...

Some statistics (running ifconfig > /dev/null on a different setup):

iface count / IPv6 no-patch time / IPv6 patched time / IPv4 time

Subject: [PATCH 1937/1958] ath6kl: revert USB support

The ath6kl driver is causing build failures when the ath6kl bits are
not built as modules.  A better fix is forthcoming in a future release,
but for now lets revert the problematic code.

This reverts the following commits:

	fde57764ef8751b9aca11b6f6221ac5555bda699
	d70385a26ad9a122a5450d066550470107b6bc38

Subject: [PATCH 1938/1958] e1000: fix lockdep splat in shutdown handler

As reported by Steven Rostedt, e1000 has a lockdep splat added
during the recent merge window.  The issue is that
cancel_delayed_work is called while holding our private mutex.

There is no reason that I can see to hold the mutex during pci
shutdown, it was more just paranoia that I put the mutex_lock
around the call to e1000_down.

In a quick survey lots of drivers handle locking differently when
being called by the pci layer.  The assumption here is that we
don't need the mutexes' protection in this function because
the driver could not be unloaded while in the shutdown handler
which is only called at reboot or poweroff.

Subject: [PATCH 1942/1958] igb: add basic runtime PM support

Use the runtime power management framework to add basic runtime PM support
to the igb driver. Namely, make the driver suspend the device when the link
is off and set it up for generating a wakeup event after the link has been
detected again. This feature is disabled by default.

Based on e1000e's runtime PM code.

Changes since v1:
Don't suspend the device when shutting down the interface.
Avoid race between runtime suspending and ethtool operations.

Subject: [PATCH 1943/1958] igb: reset PHY after recovering from PHY power down

According to 82576_Datasheet.pdf, PHY setting is lost after PHY power down.
So resetting PHY is needed when recovering from PHY power down to set a default
setting to PHY register.
Owing to this lack, NIC doesn't link up in some rare situation.

Subject: [PATCH 1944/1958] netdev: FCoE: Add new ndo_get_fcoe_hbainfo() call

This adds a new ndo_get_fcoe_hbainfo() call in
net_device_ops for FCoE protocol stack.

If supported by the underlying device, the FCoE protocol
stack will call this to get device specific information
from the underlying device.
This information will then be utilized by the FCoE protocol
stack to register Fiber Channel HBA attributes with the
Fiber Channel Management Service via Fabric Device
Management Interface (FDMI) as per the T11 FC-GS
specification.

Changes in v2:
- As per comments from David Miller aligning the parameters
of the ndo_get_fcoe_hbainfo()

Subject: [PATCH 1946/1958] virtio_net: Pass gfp flags when allocating rx
 buffers.

Currently, the refill path for RX buffers will always allocate the
buffers as GFP_ATOMIC, even if we are in process context.  This will
fail to apply memory pressure as the worker thread will not contribute
to the freeing of memory.

Fix this by changing add_recvbuf_small to use the gfp variant allocator,
__netdev_alloc_skb_ip_align().

Not now, but it looks you are correct. q->qdisc is NULL until another

The following patch should work.

Subject: [PATCH 1955/1958] cnic: Improve error recovery on bnx2x devices

When a bnx2x device encounters parity errors, it will not respond to all
SPQ messages.  As a result, the shutdown sequence before reset can take
a long time as the ulp drivers (bnx2i/bnx2fc) have to wait for timeout
of all such messages.

To improve this scenario, when bnx2x returns error on the SPQ, we'll send
an immediate response to the ulp drivers to avoid such lengthy timeouts.

Adjust the return code of relevant functions to return error only if
the message cannot be sent on the SPQ so that we'll generate an error
completion to the ulp drivers.

Subject: [PATCH 1956/1958] net_sched: sfq: extend limits

SFQ as implemented in Linux is very limited, with at most 127 flows
and limit of 127 packets. [ So if 127 flows are active, we have one
packet per flow ]

This patch brings to SFQ following features to cope with modern needs.

- Ability to specify a smaller per flow limit of inflight packets.
    (default value being at 127 packets)

- Ability to have up to 65408 active flows (instead of 127)

- Ability to have head drops instead of tail drops
  (to drop old packets from a flow)

Example of use : No more than 20 packets per flow, max 8000 flows, max
20000 packets in SFQ qdisc, hash table of 65536 slots.

tc qdisc add ... sfq \
        flows 8000 \
        depth 20 \
        headdrop \
        limit 20000 \
	divisor 65536

Ram usage :

2 bytes per hash table entry (instead of previous 1 byte/entry)
32 bytes per flow on 64bit arches, instead of 384 for QFQ, so much
better cache hit ratio.

From eeca6688d6599c28bc449a45facb67d7f203be74 Mon Sep 17 00:00:00 2001
From: Eric Dumazet <eric.dumazet@gmail.com>
Date: Thu, 5 Jan 2012 02:25:16 +0000
Subject: [PATCH 1957/1958] net_sched: red: split red_parms into parms and vars

This patch splits the red_parms structure into two components.

One holding the RED 'constant' parameters, and one containing the
variables.

This permits a size reduction of GRED qdisc, and is a preliminary step
to add an optional RED unit to SFQ.

SFQRED will have a single red_parms structure shared by all flows, and a
private red_vars per flow.

From 9f42f126154786e6e76df513004800c8c633f020 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1958/1958] net: pack skb_shared_info more efficiently

nr_frags can be 8 bits since 256 is plenty of fragments. This allows it to be
packed with tx_flags.

Also by moving ip6_frag_id and dataref (both 4 bytes) next to each other we can
avoid a hole between ip6_frag_id and frag_list on 64 bit systems.
