2009-01-26inotify: clean up inotify_read and fix locking problemsVegard Nossum
If userspace supplies an invalid pointer to a read() of an inotify instance, the inotify device's event list mutex is unlocked twice. This causes an unbalance which effectively leaves the data structure unprotected, and we can trigger oopses by accessing the inotify instance from different tasks concurrently. The best fix (contributed largely by Linus) is a total rewrite of the function in question: On Thu, Jan 22, 2009 at 7:05 AM, Linus Torvalds wrote: > The thing to notice is that: > > - locking is done in just one place, and there is no question about it > not having an unlock. > > - that whole double-while(1)-loop thing is gone. > > - use multiple functions to make nesting and error handling sane > > - do error testing after doing the things you always need to do, ie do > this: > > mutex_lock(..) > ret = function_call(); > mutex_unlock(..) > > .. test ret here .. > > instead of doing conditional exits with unlocking or freeing. > > So if the code is written in this way, it may still be buggy, but at least > it's not buggy because of subtle "forgot to unlock" or "forgot to free" > issues. > > This _always_ unlocks if it locked, and it always frees if it got a > non-error kevent.

2009-01-26fuse: fix poll notifyMiklos Szeredi
Move fuse_copy_finish() to before calling fuse_notify_poll_wakeup(). This is not a big issue because fuse_notify_poll_wakeup() should be atomic, but it's cleaner this way, and later uses of notification will need to be able to finish the copying before performing some actions.

2009-01-26fuse: destroy bdi on umountMiklos Szeredi
If a fuse filesystem is unmounted but the device file descriptor remains open and a new mount reuses the old device number, then the mount fails with EEXIST and the following warning is printed in the kernel log: WARNING: at fs/sysfs/dir.c:462 sysfs_add_one+0x35/0x3d() sysfs: duplicate filename '0:15' can not be created The cause is that the bdi belonging to the fuse filesystem was destoryed only after the device file was released. Fix this by calling bdi_destroy() from fuse_put_super() instead. Signed-off-by: Miklos Szeredi <mszeredi@suse.cz> CC: stable@kernel.org

2009-01-22Long btree pointers are still 64 bit on diskDave Chinner
[XFS] Long btree pointers are still 64 bit on disk On 32 bit machines with CONFIG_LBD=n, XFS reduces the in memory size of xfs_fsblock_t to 32 bits so that it will fit within 32 bit addressing. However, the disk format for long btree pointers are still 64 bits in size. The recent btree rewrite failed to take this into account when initialising new btree blocks, setting sibling pointers to NULL and checking if they are NULL. Hence checking whether a 64 bit NULL was the same as a 32 bit NULL was failingi resulting in NULL sibling pointers failing to be detected correctly. This showed up as WANT_CORRUPTED_GOTO shutdowns in xfs_btree_delrec. Fix this by making all the comparisons and setting of long pointer btree NULL blocks to the disk format, not the in memory format. i.e. use NULLDFSBNO.

2009-01-21dlm: initialize file_lock struct in GETLK before copying conflicting lockJeff Layton
dlm_posix_get fills out the relevant fields in the file_lock before returning when there is a lock conflict, but doesn't clean out any of the other fields in the file_lock. When nfsd does a NFSv4 lockt call, it sets the fl_lmops to nfsd_posix_mng_ops before calling the lower fs. When the lock comes back after testing a lock on GFS2, it still has that field set. This confuses nfsd into thinking that the file_lock is a nfsd4 lock. Fix this by making DLM reinitialize the file_lock before copying the fields from the conflicting lock.
