| * [XFS] Fix block reservation mechanism.David Chinner2007-02-104-20/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The block reservation mechanism has been broken since the per-cpu superblock counters were introduced. Make the block reservation code work with the per-cpu counters by syncing the counters, snapshotting the amount of available space and then doing a modifcation of the counter state according to the result. Continue in a loop until we either have no space available or we reserve some space.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The free block modification code has a 32bit interface, limiting the size the filesystem can be grown even on 64 bit machines. On 32 bit machines, there are other 32bit variables in transaction structures and interfaces that need to be expanded to allow this to work.

| * [XFS] Reduction global superblock lock contention near ENOSPC.David Chinner2007-02-102-93/+140
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing per-cpu superblock counter code uses the global superblock spin lock when we approach ENOSPC for global synchronisation. On larger machines than this code was originally tested on this can still get catastrophic spinlock contention due increasing rebalance frequency near ENOSPC. By introducing a sleeping lock that is used to serialise balances and modifications near ENOSPC we prevent contention from needlessly from wasting the CPU time of potentially hundreds of CPUs. To reduce the number of balances occuring, we separate the need rebalance case from the slow allocate case. Now, a counter running dry will trigger a rebalance during which counters are disabled. Any thread that sees a disabled counter enters a different path where it waits on the new mutex. When it gets the new mutex, it checks if the counter is disabled. If the counter is disabled, then we _know_ that we have to use the global counter and lock and it is safe to do so immediately. Otherwise, we drop the mutex and go back to trying the per-cpu counters which we know were re-enabled.

| * [XFS] Keep stack usage down for 4k stacks by using noinline.David Chinner2007-02-1023-63/+87
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | gcc-4.1 and more recent aggressively inline static functions which increases XFS stack usage by ~15% in critical paths. Prevent this from occurring by adding noinline to the STATIC definition. Also uninline some functions that are too large to be inlined and were causing problems with CONFIG_FORCED_INLINING=y. Finally, clean up all the different users of inline, __inline and __inline__ and put them under one STATIC_INLINE macro. For debug kernels the STATIC_INLINE macro uninlines those functions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The message buffer used by cmn_err() is only 256 bytes and some CXFS messages were exceeding this length. Since we were using vsprintf() and not checking for buffer overruns we were clobbering memory beyond the buffer. The size of the buffer has been increased to 1024 bytes so we can capture these larger messages and we are now using vsnprintf() to prevent overrunning the buffer size.

| * [XFS] Fix a synchronous buftarg flush deadlock when freezing.David Chinner2007-02-101-57/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At the last stage of a freeze, we flush the buftarg synchronously over and over again until it succeeds twice without skipping any buffers. The delwri list flush skips pinned buffers, but tries to flush all others. It removes the buffers from the delwri list, then tries to lock them one at a time as it traverses the list to issue the I/O. It holds them locked until we issue all of the I/O and then unlocks them once we've waited for it to complete. The problem is that during a freeze, the filesystem may still be doing stuff - like flushing delalloc data buffers - in the background and hence we can be trying to lock buffers that were on the delwri list at the same time. Hence we can get ABBA deadlocks between threads doing allocation and the buftarg flush (freeze) thread. Fix it by skipping locked (and pinned) buffers as we traverse the delwri buffer list.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some partitioning systems create special partitions that span the entire disk. One example are Sun partitions, and this whole-disk partition exists to tell the firmware the extent of the entire device so it can load the boot block and do other things. Such partitions should not be treated as normal partitions, because all the other partitions overlap this whole-disk one. So we'd see multiple instances of the same UUID etc. which we do not want. udev and friends can thus search for this 'whole_disk' attribute and use it to decide to ignore the partition.

Mingming later sent the same patch, saying: We are running SDET benchmark and saw double free issue for ext3 extended attributes block, which complains the same xattr block already being freed (in ext3_xattr_release_block()). The problem could also been triggered by multiple threads loop untar/rm a kernel tree. The race is caused by missing a memory barrier at unlock_buffer() before the lock bit being cleared, resulting in possible concurrent h_refcounter update. That causes a reference counter leak, then later leads to the double free that we have seen. Inside unlock_buffer(), there is a memory barrier is placed *after* the lock bit is being cleared, however, there is no memory barrier *before* the bit is cleared. On some arch the h_refcount update instruction and the clear bit instruction could be reordered, thus leave the critical section re-entered. The race is like this: For example, if the h_refcount is initialized as 1, cpu 0: cpu1 -------------------------------------- ----------------------------------- lock_buffer() /* test_and_set_bit */ clear_buffer_locked(bh); lock_buffer() /* test_and_set_bit */ h_refcount = h_refcount+1; /* = 2*/ h_refcount = h_refcount + 1; /*= 2 */ clear_buffer_locked(bh); .... ...... We lost a h_refcount here. We need a memory barrier before the buffer head lock bit being cleared to force the order of the two writes. Please apply.

* | [PATCH] extend the set of "__attribute__" shortcut macrosRobert P. J. Day2007-02-112-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extend the set of "__attribute__" shortcut macros, and remove identical (and now superfluous) definitions from a couple of source files. based on a page at robert love's blog: http://rlove.org/log/2005102601 extend the set of shortcut macros defined in compiler-gcc.h with the following: #define __packed __attribute__((packed)) #define __weak __attribute__((weak)) #define __naked __attribute__((naked)) #define __noreturn __attribute__((noreturn)) #define __pure __attribute__((pure)) #define __aligned(x) __attribute__((aligned(x))) #define __printf(a,b) __attribute__((format(printf,a,b))) Once these are in place, it's up to subsystem maintainers to decide if they want to take advantage of them. there is already a strong precedent for using shortcuts like this in the source tree. The ones that might give people pause are "__aligned" and "__printf", but shortcuts for both of those are already in use, and in some ways very confusingly. note the two very different definitions for a macro named "ALIGNED": drivers/net/sgiseeq.c:#define ALIGNED(x) ((((unsigned long)(x)) + 0xf) & ~(0xf)) drivers/scsi/ultrastor.c:#define ALIGNED(x) __attribute__((aligned(x))) also: include/acpi/platform/acgcc.h: #define ACPI_PRINTF_LIKE(c) __attribute__ ((__format__ (__printf__, c, c+1))) Given the precedent, then, it seems logical to at least standardize on a consistent set of these macros.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix insecure default behaviour reported by Tigran Aivazian: if an ext2 or ext3 or ext4 filesystem is tuned to mount with "acl", but mounted by a kernel built without ACL support, then umask was ignored when creating inodes - though root or user has umask 022, touch creates files as 0666, and mkdir creates directories as 0777. This appears to have worked right until 2.6.11, when a fix to the default mode on symlinks (always 0777) assumed VFS applies umask: which it does, unless the mount is marked for ACLs; but ext[234] set MS_POSIXACL in s_flags according to s_mount_opt set according to def_mount_opts. We could revert to the 2.6.10 ext[234]_init_acl (adding an S_ISLNK test); but other filesystems only set MS_POSIXACL when ACLs are configured. We could fix this at another level; but it seems most robust to avoid setting the s_mount_opt flag in the first place (at the expense of more ifdefs). Likewise don't set the XATTR_USER flag when built without XATTR support.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch to identify AIX disks and ignore them has caused at least one machine to fail to find the root partition on 2.6.19. The patch is: http://lkml.org/lkml/2006/7/31/117 The problem is some disk formatters do not blow away the first 4 bytes of the disk. If the disk we are installing to used to have AIX on it, then the first 4 bytes will still have IBMA in EBCDIC. The install in question was debian etch. Im not sure what the best fix is, perhaps the AIX detection code could check more than the first 4 bytes. The whole partition info for primary partitions is in this block: dd if=/dev/sdb count=$(( 4 * 16 )) bs=1 skip=$(( 0x1be )) All other data do not matter, beside the 0x55aa marker at the end of the first block.

* | [PATCH] ext2: skip pages past number of blocks in ext2_find_entryEric Sandeen2007-02-111-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This one was pointed out on the MOKB site: http://kernelfun.blogspot.com/2006/11/mokb-09-11-2006-linux-26x-ext2checkpage.html If a directory's i_size is corrupted, ext2_find_entry() will keep processing pages until the i_size is reached, even if there are no more blocks associated with the directory inode. This patch puts in some minimal sanity-checking so that we don't keep checking pages (and issuing errors) if we know there can be no more data to read, based on the block count of the directory inode. This is somewhat similar in approach to the ext3 patch I sent earlier this year.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | When igrab() is calling __iget() on an inode it should check if clear_inode() has been called on the inode already. Otherwise there is a race window between clear_inode() and destroy_inode() where igrab() calls __iget() which leads to already free inodes on the inode lists.

| | | | | | | | | | | | | | | remap() the region we get from mmap() to mark the fact that we are using all of the available slack space. Any slack space is used to form a simple brk region, and potentially more stack space than requested at load time. Any searches of the vma chain may well fail looking for stack (and especially arg) addresses if the remaping is not done. The simplest example is /proc/<pid>/cmdline, since the args are pretty much always at the top of the data/bss/stack region.

* [PATCH] hugetlb: preserve hugetlb pte dirty stateKen Chen2007-02-091-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | __unmap_hugepage_range() is buggy that it does not preserve dirty state of huge_pte when unmapping hugepage range. It causes data corruption in the event of dop_caches being used by sys admin. For example, an application creates a hugetlb file, modify pages, then unmap it. While leaving the hugetlb file alive, comes along sys admin doing a "echo 3 > /proc/sys/vm/drop_caches". drop_pagecache_sb() will happily free all pages that aren't marked dirty if there are no active mapping. Later when application remaps the hugetlb file back and all data are gone, triggering catastrophic flip over on application. Not only that, the internal resv_huge_pages count will also get all messed up. Fix it up by marking page dirty appropriately.

| | | | | | | | | | | | | | | | | | | | | | | This is a fix of regression, which triggered by ~2.6.16. Patch with name ufs-directory-and-page-cache-from-blocks-to-pages.patch: in additional to conversation from block to page cache mechanism added new checks of directory integrity, one of them that directory entry do not across directory chunks. But some kinds of UFS: OpenStep UFS and Apple UFS (looks like these are the same filesystems) have different directory chunk size, then common UFSes(BSD and Solaris UFS). So this patch adds ability to works with variable size of directory chunks, and set it for ufstype=openstep to right size. Tested on darwin ufs.
