2006-08-10[XFS] Fix xfs_free_extent related NULL pointer dereference.Nathan Scott
We recently fixed an out-of-space deadlock in XFS, and part of that fix involved the addition of the XFS_ALLOC_FLAG_FREEING flag to some of the space allocator calls to indicate they're freeing space, not allocating it. There was a missed xfs_alloc_fix_freelist condition test that did not correctly test "flags". The same test would also test an uninitialised structure field (args->userdata) and depending on its value either would or would not return early with a critical buffer pointer set to NULL. This fixes that up, adds asserts to several places to catch future botches of this nature, and skips sections of xfs_alloc_fix_freelist that are irrelevent for the space-freeing case.

2006-08-06[PATCH] udf: initialize parts of inode earlier in createEric Sandeen
I saw an oops down this path when trying to create a new file on a UDF filesystem which was internally marked as readonly, but mounted rw: udf_create udf_new_inode new_inode alloc_inode udf_alloc_inode udf_new_block returns EIO due to readonlyness iput (on error) udf_put_inode udf_discard_prealloc udf_next_aext udf_current_aext udf_get_fileshortad OOPS the udf_discard_prealloc() path was examining uninitialized fields of the udf inode. udf_discard_prealloc() already has this code to short-circuit the discard path if no extents are preallocated: if (UDF_I_ALLOCTYPE(inode) == ICBTAG_FLAG_AD_IN_ICB || inode->i_size == UDF_I_LENEXTENTS(inode)) { return; } so if we initialize UDF_I_LENEXTENTS(inode) = 0 earlier in udf_new_inode, we won't try to free the (not) preallocated blocks, since this will match the i_size = 0 set when the inode was initialized.

2006-08-06[PATCH] reiserfs_write_full_page() should not get_block past eofChris Mason
reiserfs_write_full_page does zero bytes in the file past eof, but it may call get_block on those buffers as well. On machines where the page size is larger than the blocksize, this can result in mmaped files incorrectly growing up to a block boundary during writepage. The fix is to avoid calling get_block for any blocks that are entirely past eof Signed-off-by: Chris Mason <mason@suse.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-08-06[PATCH] Fix BeFS slab corruptionDiego Calleja
In bugzilla #6941, Jens Kilian reported: "The function befs_utf2nls (in fs/befs/linuxvfs.c) writes a 0 byte past the end of a block of memory allocated via kmalloc(), leading to memory corruption. This happens only for filenames which are pure ASCII and a multiple of 4 bytes in length. [...] Without DEBUG_SLAB, this leads to further corruption and hard lockups; I believe this is the bug which has made kernels later than 2.6.8 unusable for me. (This must be due to changes in memory management, the bug has been in the BeFS driver since the time it was introduced (AFAICT).) Steps to reproduce: Create a directory (in BeOS, naturally :-) with files named, e.g., "1", "22", "333", "4444", ... Mount it in Linux and do an "ls" or "find"" This patch implements the suggested fix. Credits to Jens Kilian for debugging the problem and finding the right fix.

2006-07-31[PATCH] fuse: use jiffies_64Miklos Szeredi
It is entirely possible (though rare) that jiffies half-wraps around, while a dentry/inode remains in the cache. This could mean that the dentry/inode is not invalidated for another half wraparound-time. To get around this problem, use 64-bit jiffies. The only problem with this is that dentry->d_time is 32 bits on 32-bit archs. So use d_fsdata as the high 32 bits. This is an ugly hack, but far simpler, than having to allocate private data just for this purpose. Since 64-bit jiffies can be assumed never to wrap around, simple comparison can be used, and a zero time value can represent "invalid".

2006-07-31[PATCH] inotify: fix deadlock found by lockdepArjan van de Ven
This is a real deadlock, a nice complex one: (warning: long explanation follows so that Andrew can have a complete patch description) it's an ABCDA deadlock: A iprune_mutex B inode->inotify_mutex C ih->mutex D dev->ev_mutex The AB relationship comes straight from invalidate_inodes() int invalidate_inodes(struct super_block * sb) { int busy; LIST_HEAD(throw_away); mutex_lock(&iprune_mutex); spin_lock(&inode_lock); inotify_unmount_inodes(&sb->s_inodes); where inotify_umount_inodes() takes the mutex_lock(&inode->inotify_mutex); The BC relationship comes directly from inotify_find_update_watch(): s32 inotify_find_update_watch(struct inotify_handle *ih, struct inode *inode, u32 mask) { ... mutex_lock(&inode->inotify_mutex); mutex_lock(&ih->mutex); The CD relationship comes from inotify_rm_wd: inotify_rm_wd does mutex_lock(&inode->inotify_mutex); mutex_lock(&ih->mutex) and then calls inotify_remove_watch_locked() which calls notify_dev_queue_event() which does mutex_lock(&dev->ev_mutex); (this strictly is a BCD relationship) The DA relationship comes from the most interesting part: [<ffffffff8022d9f2>] shrink_icache_memory+0x42/0x270 [<ffffffff80240dc4>] shrink_slab+0x11d/0x1c9 [<ffffffff802b5104>] try_to_free_pages+0x187/0x244 [<ffffffff8020efed>] __alloc_pages+0x1cd/0x2e0 [<ffffffff8025e1f8>] cache_alloc_refill+0x3f8/0x821 [<ffffffff8020a5e5>] kmem_cache_alloc+0x85/0xcb [<ffffffff802db027>] kernel_event+0x2e/0x122 [<ffffffff8021d61c>] inotify_dev_queue_event+0xcc/0x140 inotify_dev_queue_event schedules a kernel_event which does a kmem_cache_alloc( , GFP_KERNEL) which may try to shrink slabs, including the inode cache .. which then takes iprune_mutex. And voila, there is an AB, a BC, a CD relationship (even a direct BCD), and also now a DA relationship -> a circular type AB-BA deadlock but involving 4 locks. The solution is simple: kernel_event() is NOT allowed to use GFP_KERNEL, but must use GFP_NOFS to not cause recursion into the VFS.

This had the unfortunately side-effect of moving *after* the call to decode_fh, so the prober fsuid was not set when nfsd_acceptable was called, the 'permission' check did the wrong thing.

2006-07-31[PATCH] ext3: avoid triggering ext3_error on bad NFS file handleNeil Brown
The inode number out of an NFS file handle gets passed eventually to ext3_get_inode_block() without any checking. If ext3_get_inode_block() allows it to trigger an error, then bad filehandles can have unpleasant effect - ext3_error() will usually cause a forced read-only remount, or a panic if `errors=panic' was used. So remove the call to ext3_error there and put a matching check in ext3/namei.c where inode numbers are read off storage.
