* [PATCH] v9fs: simplify fid mappingEric Van Hensbergen2006-03-02
| | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] v9fs: fix atomic create openLatchesar Ionkov2006-03-02
| | | | | | | | | | | | | | In order to assure atomic create+open v9fs stores the open fid produced by v9fs_vfs_create in the dentry, from where v9fs_file_open retrieves it and associates it with the open file. This patch modifies v9fs to use nameidata.intent.open values to do the atomic create+open.

* [PATCH] Add mm->task_size and fix powerpc vdsoBenjamin Herrenschmidt2006-02-28
| | | | | | | | | | | | | | | 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. It may need tweaks, but at this stage this patch is powerpc-only.)

* [PATCH] fuse: fix bug in negative lookupMiklos Szeredi2006-02-28
| | | | | | | | | | | | | | | | | | 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.

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?

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.

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.

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.
