I've solved the problem I was having with the simulator and not booting Debian. The problem is that the number of bits for the virtual linear array short-format VHPT (Virtually mapped linear page table, VMLPT for short) is being tested incorrectly. There are two problems: 1. The PAL call that should tell the kernel the size of the virtual address space isn't implemented for the simulator, so the kernel uses the default 50. This is addressed separately in dc90e95f310f4f821c905b2aec8e9449bb3270fa 2. In arch/ia64/mm/init.c there's code to calcualte the size of the VMLPT based on the number of implemented virtual address bits and the page size. It checks to see if the VMLPT base address overlaps the top of the mapped region, but this check doesn't allow for the address space hole, and in fact will never trigger. Here's an alternative test and panic, that I think is more accurate.

New function hid_size_buffers() that calculates the longest report for each endpoint and stores the result in the hid_device object. These lengths are used to allocate buffers that are large enough to store any report on the endpoint. For compatibility, the minimum size for an endpoint buffer set to HID_BUFFER_SIZE rather than the known optimal case (the longest report length). It fixes bug #3063 in bugzilla.

This happens where hid_submit_report() (in hid-core.c) tests for HID_CTRL_RUNNING, which seems to be still set because the first transfer is not finished yet. As a workaround, inserting a delay between the two calls to ioctl(HIDIOCSREPORT) in userspace "solves" the problem. The straightforward fix is to add a call to hid_wait_io() to the implementation of HIDIOCSREPORT (in hiddev.c), just like for HIDIOCGREPORT. Works fine for me.

OCFS2 wants this so it can query the cluster before making a final decision on whether to wipe an inode from disk or not. In some corner cases an inode marked on the local node via voting may not actually get orphaned. A good example is node death before the transaction moving the inode to the orphan dir commits to the journal. Without this patch, the truncate_inode_pages() call in generic_delete_inode() would discard valid data for such inodes. During earlier discussion in the 2.6.13 merge plan thread, Christoph Hellwig indicated that other file systems might also find this useful. IMHO, the best solution would be to just allow ->drop_inode() to do the cluster query but it seems that would require a substantial reworking of that section of the code. Assuming it is safe to call write_inode_now() in ocfs2_delete_inode() for those inodes which won't actually get wiped, this solution should get us by for now. Trivial testing of this patch (and a related OCFS2 update) has shown this to avoid the corruption I'm seeing.

This parallels the existing processing for setting ACLs on newly created inodes. Otherwise, it is possible for new inodes to be accessed by another thread via the dcache prior to complete security setup (presently handled by the post_create/mkdir/... LSM hooks in the VFS) and a newly created inode may be left unlabeled on the disk in the event of a crash. SELinux presently works around the issue by ensuring that the incore inode security label is initialized to a special SID that is inaccessible to unprivileged processes (in accordance with policy), thereby preventing inappropriate access but potentially causing false denials on legitimate accesses. A simple test program demonstrates such false denials on SELinux, and the patch solves the problem. Similar such false denials have been encountered in real applications. This patch defines a new inode_init_security LSM hook to obtain the security attribute to apply to a newly created inode and to set up the incore inode security state for it, and adds a corresponding hook function implementation to SELinux.

As there is no underlying storage of security xattrs in this case, it is not necessary for the hook to return the (name, value, len) triple to the tmpfs code, so this patch also modifies the SELinux hook function to correctly handle the case where the (name, value, len) pointers are NULL. The hook call is needed in tmpfs in order to support proper security labeling of tmpfs inodes (e.g. for udev with tmpfs /dev in Fedora). With this change in place, we should then be able to remove the security_inode_post_create/mkdir/... hooks safely.

This was found by Roland. This was harmless from a security standpoint, but some i686 users reported failures with auditing enabled system wide (some distro surprisingly makes it the default) and I reproduced it too by keeping the whole workload under strace -f.

Because of this, one .got entry is allocated for each relocation instead of one each unique symbol/addend. In the module I am working with, this causes the .got section to be almost 10 times larger than it needs to be (75544 bytes instead of 7608 bytes). As the .got is accessed with global-pointer-relative instructions, it needs to be within the 64k gp "zone", and a 75544 byte .got clearly does not fit. The result of this is that relocation overflows are detected during module load and the load is aborted. Change struct got_entry/process_reloc_for_got to fix this.

This is needed to ensure that say a poll on one side of the pty doesn't occur while the line discipline is actively being changed. This resulted in an oops reported on lkml, see: http://marc.theaimsgroup.com/?l=linux-kernel&m=111342171410005&w=2 A 'hacky' approach was previously implmemented which served to eliminate the poll vs. line discipline changing race. However, this patch takes a more general approach to the issue. The patch only adds locking on a less often used path, the line-discipline changing path, as opposed to locking the ptmx/pty pair on read/write/poll paths. The patch below, takes both ldisc locks in either order b/c the locks are both taken under the same spinlock(). I thought about locking the ptmx/pty separately, such as master always first but that introduces a 3 way deadlock. For example, process 1 does a blocking read on the slave side. Then, process 2 does an ldisc change on the slave side, which acquires the master ldisc lock but not the slave's. Finally, process 3 does a write which blocks on the process 2's ldisc reference. This patch does introduce some changes in semantics. For example, a line discipline change on side 'a' of a ptmx/pty pair, will now wait for a read/write to complete on the other side, or side 'b'. The current behavior is to simply wait for any read/writes on only side 'a', not both sides 'a' and 'b'. I think this behavior makes sense, but I wanted to point it out. I've tested the patch with a bunch of read/write/poll while changing the line discipline out from underneath. This patch obviates the need for the above "hide the problem" patch.

Here is a patch to correct that. It corrects the disp_end and offset registers of the vga board on console resize and console switch. On usual screens, you then correctly get a right and/or bottom blank margin. On some laptop panels, the output is resized so that text actually gets magnified, which can be great for some people (see http://dept-info.labri.fr/~thibault/ls.jpg ).

Process A forks process B, both being part of the same session. Then, A calls disassociate_ctty while B forks C: A B ==== ==== fork() copy_signal() dissasociate_ctty() .... attach_pid(p, PIDTYPE_SID, p->signal->session); Now, C can have current->signal->tty pointing to a freed tty structure, as it hasn't yet been added to the session group (to have its controlling tty cleared on the diassociate_ctty() call). This has shown up as an oops but could be even more serious. I haven't tried to create a test case, but a customer has verified that the patch below resolves the issue, which was occuring quite frequently. I'll try and post the test case if i can. The patch simply checks for a NULL tty *after* it has been attached to the proper session group and clears it as necessary. Alternatively, we could simply do the tty assignment after the the process is added to the proper session group.

For context switch intensive application, we found that significant amount of cache misses occurs in switch_to() function. The following patch adds a hook in the schedule() function to prefetch switch stack structure as soon as 'next' task is determined. This allows maximum overlap in prefetch cache lines for that structure.

I have tried all combinations of the kernel "reboot=x,y" flags to no avail. Rebooting by any method will leave the system in a wedged state (at the "Restarting system" message). I finally tracked the problem down to the machine's refusal to fully reboot unless the keyboard controller status register had bit 2 set. This is the "System flag" which when set, indicates successful completion of the keyboard controller self-test (Basic Assurance Test, BAT). I suppose that something is trying to protect against sporadic reboots unless the keyboard controller is in a good state (a keyboard is present), but I need this machine to be headless. I found that setting the system flag (via the command byte) before giving the "pulse reset line" command will allow the reboot to proceed. The patch is simple, and I think it should be fine for everybody whether they have this type of machine or not.

This patch has been tested on dvb-kernel cvs, and has been reported to work by multiple users. Some cards still need timeout increase on top of this patch. This will be addressed later.

There is an optimization that keeps track of the frequency tuned by the digital decoder. The digital driver does not set the frequency if it has not changed since it was tuned. The analog tuner driver knows nothing about the frequency saved by the digital driver. When the frequency is set using the video4linux code with tvtime, the hardware get changed but the digital driver's state does not get updated. Switch back to the same digital channel and the driver finds no change in frequency so the tuner is not reset to the digital frequency. The work around is to remove the check and always set the tuner to the specified frequency.

Now it is possible to do slab allocations on a node to localize memory structures. This API was used by the pageset localization patch and the block layer localization patch now in mm. The existing kmalloc_node is slow since it simply searches through all pages of the slab to find a page that is on the node requested. The two patches do a one time allocation of slab structures at initialization and therefore the speed of kmalloc node does not matter. This patch allows kmalloc_node to be as fast as kmalloc by introducing node specific page lists for partial, free and full slabs. Slab allocation improves in a NUMA system so that we are seeing a performance gain in AIM7 of about 5% with this patch alone. More NUMA localizations are possible if kmalloc_node operates in an fast way like kmalloc.

Instead of ensuring this through too many memory barriers, we put the arrays and their sizes in a separate structure. This patch takes the first step of putting the file table elements in a separate structure fdtable that is embedded withing files_struct. It also changes all the users to refer to the file table using files_fdtable() macro. Subsequent applciation of RCU becomes easier after this.

The updates to the fdtable are done by allocating a new fdtable structure and setting files->fdt to point to the new structure. The fdtable structure is protected by RCU thereby allowing lock-free lookup. For fd arrays/sets that are vmalloced, we use keventd to free them since RCU callbacks can't sleep. A global list of fdtable to be freed is not scalable, so we use a per-cpu list. If keventd is already handling the current cpu's work, we use a timer to defer queueing of that work. Since the last publication, this patch has been re-written to avoid using explicit memory barriers and use rcu_assign_pointer(), rcu_dereference() premitives instead. This required that the fd information is kept in a separate structure (fdtable) and updated atomically.

Typically +this would be the case for posix threads. As with the common +refcounting model in the kernel, the last task doing +a put_files_struct() frees the file descriptor (fd) table. +The files (struct file) themselves are protected using +reference count (->f_count). + +In the new lock-free model of file descriptor management, +the reference counting is similar, but the locking is +based on RCU. The file descriptor table contains multiple +elements - the fd sets (open_fds and close_on_exec, the +array of file pointers, the sizes of the sets and the array +etc.). In order for the updates to appear atomic to +a lock-free reader, all the elements of the file descriptor +table are in a separate structure - struct fdtable. +files_struct contains a pointer to struct fdtable through +which the actual fd table is accessed. Initially the +fdtable is embedded in files_struct itself. On a subsequent +expansion of fdtable, a new fdtable structure is allocated +and files->fdtab points to the new structure. The fdtable +structure is freed with RCU and lock-free readers either +see the old fdtable or the new fdtable making the update +appear atomic. Here are the locking rules for +the fdtable structure - + +1. All references to the fdtable must be done through + the files_fdtable() macro : + + struct fdtable *fdt; + + rcu_read_lock(); + + fdt = files_fdtable(files); + .... + if (n <= fdt->max_fds) + .... + ... + rcu_read_unlock(); + + files_fdtable() uses rcu_dereference() macro which takes care of + the memory barrier requirements for lock-free dereference. + The fdtable pointer must be read within the read-side + critical section. + +2. Reading of the fdtable as described above must be protected + by rcu_read_lock()/rcu_read_unlock(). + +3. For any update to the the fd table, files->file_lock must + be held. + +4. To look up the file structure given an fd, a reader + must use either fcheck() or fcheck_files() APIs. These + take care of barrier requirements due to lock-free lookup. + An example : + + struct file *file; + + rcu_read_lock(); + file = fcheck(fd); + if (file) { + ... + } + .... + rcu_read_unlock(); + +5. Handling of the file structures is special. Since the look-up + of the fd (fget()/fget_light()) are lock-free, it is possible + that look-up may race with the last put() operation on the + file structure. This is avoided using the rcuref APIs + on ->f_count : + + rcu_read_lock(); + file = fcheck_files(files, fd); + if (file) { + if (rcuref_inc_lf(&file->f_count)) + *fput_needed = 1; + else + /* Didn't get the reference, someone's freed */ + file = NULL; + } + rcu_read_unlock(); + .... + return file; + + rcuref_inc_lf() detects if refcounts is already zero or + goes to zero during increment. If it does, we fail + fget()/fget_light(). + +6. Since both fdtable and file structures can be looked up + lock-free, they must be installed using rcu_assign_pointer() + API. If they are looked up lock-free, rcu_dereference() + must be used. However it is advisable to use files_fdtable() + and fcheck()/fcheck_files() which take care of these issues. + +7. While updating, the fdtable pointer must be looked up while + holding files->file_lock. If ->file_lock is dropped, then + another thread expand the files thereby creating a new + fdtable and making the earlier fdtable pointer stale. + For example : + + spin_lock(&files->file_lock); + fd = locate_fd(files, file, start); + if (fd >= 0) { + /* locate_fd() may have expanded fdtable, load the ptr */ + fdt = files_fdtable(files); + FD_SET(fd, fdt->open_fds); + FD_CLR(fd, fdt->close_on_exec); + spin_unlock(&files->file_lock); + ..... + + Since locate_fd() can drop ->file_lock (and reacquire ->file_lock), + the fdtable pointer (fdt) must be loaded after locate_fd(). + -- GitLab From 93fa58cb831337fdf5d36b3b913441100a484dae Mon Sep 17 00:00:00 2001 From: Eric Van Hensbergen Date: Fri, 9 Sep 2005 13:04:18 -0700 Subject: [PATCH 207/563] [PATCH] v9fs: Documentation, Makefiles, Configuration OVERVIEW V9FS is a distributed file system for Linux which provides an implementation of the Plan 9 resource sharing protocol 9P. It can be used to share all sorts of resources: static files, synthetic file servers (such as /proc or /sys), devices, and application file servers (such as FUSE). BACKGROUND Plan 9 (http://plan9.bell-labs.com/plan9) is a research operating system and associated applications suite developed by the Computing Science Research Center of AT&T Bell Laboratories (now a part of Lucent Technologies), the same group that developed UNIX , C, and C++. Plan 9 was initially released in 1993 to universities, and then made generally available in 1995. Its core operating systems code laid the foundation for the Inferno Operating System released as a product by Lucent Bell-Labs in 1997. The Inferno venture was the only commercial embodiment of Plan 9 and is currently maintained as a product by Vita Nuova (http://www.vitanuova.com). After updated releases in 2000 and 2002, Plan 9 was open-sourced under the OSI approved Lucent Public License in 2003. The Plan 9 project was started by Ken Thompson and Rob Pike in 1985. Their intent was to explore potential solutions to some of the shortcomings of UNIX in the face of the widespread use of high-speed networks to connect machines. In UNIX, networking was an afterthought and UNIX clusters became little more than a network of stand-alone systems. Plan 9 was designed from first principles as a seamless distributed system with integrated secure network resource sharing. Applications and services were architected in such a way as to allow for implicit distribution across a cluster of systems. Configuring an environment to use remote application components or services in place of their local equivalent could be achieved with a few simple command line instructions. For the most part, application implementations operated independent of the location of their actual resources. Commercial operating systems haven't changed much in the 20 years since Plan 9 was conceived. Network and distributed systems support is provided by a patchwork of middle-ware, with an endless number of packages supplying pieces of the puzzle. Matters are complicated by the use of different complicated protocols for individual services, and separate implementations for kernel and application resources. The V9FS project (http://v9fs.sourceforge.net) is an attempt to bring Plan 9's unified approach to resource sharing to Linux and other operating systems via support for the 9P2000 resource sharing protocol. V9FS HISTORY V9FS was originally developed by Ron Minnich and Maya Gokhale at Los Alamos National Labs (LANL) in 1997. In November of 2001, Greg Watson setup a SourceForge project as a public repository for the code which supported the Linux 2.4 kernel. About a year ago, I picked up the initial attempt Ron Minnich had made to provide 2.6 support and got the code integrated into a 2.6.5 kernel. I then went through a line-for-line re-write attempting to clean-up the code while more closely following the Linux Kernel style guidelines. I co-authored a paper with Ron Minnich on the V9FS Linux support including performance comparisons to NFSv3 using Bonnie and PostMark - this paper appeared at the USENIX/FREENIX 2005 conference in April 2005: ( http://www.usenix.org/events/usenix05/tech/freenix/hensbergen.html ). CALL FOR PARTICIPATION/REQUEST FOR COMMENTS Our 2.6 kernel support is stabilizing and we'd like to begin pursuing its integration into the official kernel tree. We would appreciate any review, comments, critiques, and additions from this community and are actively seeking people to join our project and help us produce something that would be acceptable and useful to the Linux community. STATUS The code is reasonably stable, although there are no doubt corner cases our regression tests haven't discovered yet. It is in regular use by several of the developers and has been tested on x86 and PowerPC (32-bit and 64-bit) in both small and large (LANL cluster) deployments. Our current regression tests include fsx, bonnie, and postmark. It was our intention to keep things as simple as possible for this release -- trying to focus on correctness within the core of the protocol support versus a rich set of features. For example: a more complete security model and cache layer are in the road map, but excluded from this release. Additionally, we have removed support for mmap operations at Al Viro's request. PERFORMANCE Detailed performance numbers and analysis are included in the FREENIX paper, but we show comparable performance to NFSv3 for large file operations based on the Bonnie benchmark, and superior performance for many small file operations based on the PostMark benchmark. Somewhat preliminary graphs (from the FREENIX paper) are available (http://v9fs.sourceforge.net/perf/index.html). RESOURCES The source code is available in a few different forms: tarballs: http://v9fs.sf.net CVSweb: http://cvs.sourceforge.net/viewcvs.py/v9fs/linux-9p/ CVS: :pserver:anonymous@cvs.sourceforge.net:/cvsroot/v9fs/linux-9p Git: rsync://v9fs.graverobber.org/v9fs (webgit: http://v9fs.graverobber.org) 9P: tcp!v9fs.graverobber.org!6564 The user-level server is available from either the Plan 9 distribution or from http://v9fs.sf.net Other support applications are still being developed, but preliminary version can be downloaded from sourceforge. Documentation on the protocol has historically been the Plan 9 Man pages (http://plan9.bell-labs.com/sys/man/5/INDEX.html), but there is an effort under way to write a more complete Internet-Draft style specification (http://v9fs.sf.net/rfc). There are a couple of mailing lists supporting v9fs, but the most used is v9fs-developer@lists.sourceforge.net -- please direct/cc your comments there so the other v9fs contibutors can participate in the conversation. There is also an IRC channel: irc://freenode.net/#v9fs This part of the patch contains Documentation, Makefiles, and configuration file changes.
