| * [PATCH] Fix oops in fs/locks.c on close of file with pending locksSteve French2005-08-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent change to locks_remove_flock code in fs/locks.c changes how byte range locks are removed from closing files, which shows up a bug in cifs. The assumption in the cifs code was that the close call sent to the server would remove any pending locks on the server on this file, but that is no longer safe as the fs/locks.c code on the client wants unlock of 0 to PATH_MAX to remove all locks (at least from this client, it is not possible AFAIK to remove all locks from other clients made to the server copy of the file). Note that cifs locks are different from posix locks - and it is not possible to map posix locks perfectly on the wire yet, due to restrictions of the cifs network protocol, even to Samba without adding a new request type to the network protocol (which we plan to do for Samba 3.0.21 within a few months), but the local client will have the correct, posix view, of the lock in most cases. The correct fix for cifs for this would involve a bigger change than I would like to do this late in the 2.6.13-rc cycle - and would involve cifs keeping track of all unmerged (uncoalesced) byte range locks for each remote inode and scanning that list to remove locks that intersect or fall wholly within the range - locks that intersect may have to be reaquired with the smaller, remaining range.

| * Fix nasty ncpfs symlink handling bug.Linus Torvalds2005-08-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This bug could cause oopses and page state corruption, because ncpfs used the generic page-cache symlink handlign functions. But those functions only work if the page cache is guaranteed to be "stable", ie a page that was installed when the symlink walk was started has to still be installed in the page cache at the end of the walk. We could have fixed ncpfs to not use the generic helper routines, but it is in many ways much cleaner to instead improve on the symlink walking helper routines so that they don't require that absolute stability. We do this by allowing "follow_link()" to return a error-pointer as a cookie, which is fed back to the cleanup "put_link()" routine. This also simplifies NFS symlink handling.
