2006-03-05[CIFS] Always match oplock break (cache notification) to the right tcpSteve French3-4/+4
session when multiply mounted. Fixes slow response when cifs client is mounted to shares on multiple servers and oplock break occurs (usually due to attempt to multiply open a file). When treeids on mutiple mounted shares match and we find the wrong match first, we searched for the wrong cached files to send oplock break response for which usually meant that no matching file was found and thus the server would have to timeout the notification. Oplock break timeout is about 20 seconds on some servers so this could cause significantly slower performance on file open calls in a few cases (in particular when multiple shares are mounted from multiple servers, tree ids match, and we have a cached file which is later opened multiple times). This was the most important of the bugs that was found and fixed at Connectathon (interoperability testing event) this week.

2006-03-02[PATCH] reiserfs: fix unaligned bitmap usageJeff Mahoney1-4/+4
The bitmaps associated with generation numbers for directory entries are declared as an array of ints. On some platforms, this causes alignment exceptions. The following patch uses the standard bitmap declaration macros to declare the bitmaps, fixing the problem. Originally from Takashi Iwai.

2006-03-02[PATCH] v9fs: simplify fid mappingEric Van Hensbergen4-126/+15
v9fs has been plagued by an over-complicated approach trying to map Linux dentry semantics to Plan 9 fid semantics. Our previous approach called for aggressive flushing of the dcache resulting in several problems (including wierd cwd behavior when running /bin/pwd). This patch dramatically simplifies our handling of this fid management. Fids will not be clunked as promptly, but the new approach is more functionally correct. We now clunk un-open fids only when their dentry ref_count reaches 0 (and d_delete is called). Another simplification is we no longer seek to match fids to the process-id or uid of the action initiator. The uid-matching will need to be revisited when we fix the security model.

This patch adds mm->task_size to keep track of the task size of a given mm and uses that to fix the powerpc vdso so that it uses the mm task size to decide what pages to fault in instead of the current thread flags (which broke when ptracing). (akpm: I expect that mm_struct.task_size will become the way in which we finally sort out the confusion between 32-bit processes and 32-bit mm's.

If negative entries (nodeid == 0) were sent in reply to LOOKUP requests, two bugs could be triggered: - looking up a negative entry would return -EIO, - revaildate on an entry which turned negative would send a FORGET request with zero nodeid, which would cause an abort() in the library. The above would only happen if the 'negative_timeout=N' option was used, otherwise lookups reply -ENOENT, which worked correctly.

2006-02-25[PATCH] flags parameter for linkatUlrich Drepper1-2/+6
I'm currently at the POSIX meeting and one thing covered was the incompatibility of Linux's link() with the POSIX definition. The name. Linux does not follow symlinks, POSIX requires it does. Even if somebody thinks this is a good default behavior we cannot change this because it would break the ABI. But the fact remains that some application might want this behavior. We have one chance to help implementing this without breaking the behavior. For this we could use the new linkat interface which would need a new flags parameter. If the new parameter is AT_SYMLINK_FOLLOW the new behavior could be invoked. I do not want to introduce such a patch now. But we could add the parameter now, just don't use it. The patch below would do this. Can we get this late patch applied before the release more or less fixes the syscall API?

2006-02-22Revert mount/umount uevent removalGreg Kroah-Hartman1-1/+14
This change reverts the 033b96fd30db52a710d97b06f87d16fc59fee0f1 commit from Kay Sievers that removed the mount/umount uevents from the kernel. Some older versions of HAL still depend on these events to detect when a new device has been mounted. These events are not correctly emitted, and are broken by design, and so, should not be relied upon by any future program. Instead, the /proc/mounts file should be polled to properly detect this kind of event. A feature-removal-schedule.txt entry has been added, noting when this interface will be removed from the kernel.

2006-02-18[PATCH] fix deadlock in ext2Peter Staubach1-2/+4
Fix a deadlock possible in the ext2 file system implementation. This deadlock occurs when a file is removed from an ext2 file system which was mounted with the "sync" mount option. The problem is that ext2_xattr_delete_inode() was invoking the routine, sync_dirty_buffer(), using a buffer head which was previously locked via lock_buffer(). The first thing that sync_dirty_buffer() does is to lock the buffer head that it was passed. It does this via lock_buffer(). Oops. The solution is to unlock the buffer head in ext2_xattr_delete_inode() before invoking sync_dirty_buffer(). This makes the code in ext2_xattr_delete_inode() obey the same locking rules as all other callers of sync_dirty_buffer() in the ext2 file system implementation.

2006-02-15[PATCH] NLM: Fix the NLM_GRANTED callback checksTrond Myklebust3-12/+19
If 2 threads attached to the same process are blocking on different locks on different files (maybe even on different servers) but have the same lock arguments (i.e. same offset+length - actually quite common, since most processes try to lock the entire file) then the first GRANTED call that wakes one up will also wake the other. Currently when the NLM_GRANTED callback comes in, lockd walks the list of blocked locks in search of a match to the lock that the NLM server has granted. Although it checks the lock pid, start and end, it fails to check the filehandle and the server address. By checking the filehandle and server IP address, we ensure that this only happens if the locks truly are referencing the same file.
