2006-08-21[PATCH] Fix current_io_context() vs set_task_ioprio() raceOleg Nesterov
I know nothing about io scheduler, but I suspect set_task_ioprio() is not safe. current_io_context() initializes "struct io_context", then sets ->io_context. set_task_ioprio() running on another cpu may see the changes out of order, so ->set_ioprio(ioc) may use io_context which was not initialized properly.

2006-08-14[PATCH] fcntl(F_SETSIG) fixTrond Myklebust
fcntl(F_SETSIG) no longer works on leases because lease_release_private_callback() gets called as the lease is copied in order to initialise it. The problem is that lease_alloc() performs an unnecessary initialisation, which sets the lease_manager_ops. Avoid the problem by allocating the target lease structure using locks_alloc_lock().

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".
