NLM: Fix a memory leak in nlmsvc_testlock

2007-10-09T19:38:26Z

The recent fix for a circular lock dependency unfortunately introduced a potential memory leak in the event where the call to nlmsvc_lookup_host fails for some reason. Thanks to Roel Kluin for spotting this. Signed-off-by: Trond Myklebust Signed-off-by: Linus Torvalds

AIO: fix cleanup in io_submit_one(...)

2007-10-08T19:58:14Z

When IOCB_FLAG_RESFD flag is set and iocb->aio_resfd is incorrect, statement 'goto out_put_req' is executed. At label 'out_put_req', aio_put_req(..) is called, which requires 'req->ki_filp' set. Signed-off-by: Yan Zheng Cc: Zach Brown Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

ocfs2: Unlock mutex in local alloc failure case

2007-10-03T18:14:45Z

The fs was not unlocking the local alloc inode mutex in the code path in which it failed to find a window of free bits in the global bitmap. Signed-off-by: Sunil Mushran Signed-off-by: Mark Fasheh

Fix possible splice() mmap_sem deadlock

2007-10-01T20:17:28Z

Nick Piggin points out that splice isn't being good about the mmap semaphore: while two readers can nest inside each others, it does leave a possible deadlock if a writer (ie a new mmap()) comes in during that nesting. Original "just move the locking" patch by Nick, replaced by one by me based on an optimistic pagefault_disable(). And then Jens tested and updated that patch.

Revert "[XFS] Avoid replaying inode buffer initialisation log items if on-disk version is newer."

2007-10-01T14:59:03Z

This reverts commit b394e43e995d08821588a22561c6a71a63b4ff27. Lachlan McIlroy says: It tried to fix an issue where log replay is replaying an inode cluster initialisation transaction that should not be replayed because the inode cluster on disk is more up to date. Since we don't log file sizes (we rely on inode flushing to get them to disk) then we can't just replay all the transations in the log and expect the inode to be completely restored. We lose file size updates. Unfortunately this fix is causing more (serious) problems than it is fixing.

NFS: Fix an Oops in encode_lookup()

2007-09-28T22:36:42Z

It doesn't look as if the NFS file name limit is being initialised correctly in the struct nfs_server. Make sure that we limit whatever is being set in nfs_probe_fsinfo() and nfs_init_server(). Also ensure that readdirplus and nfs4_path_walk respect our file name limits. Signed-off-by: Trond Myklebust Signed-off-by: Linus Torvalds

NLM: Fix a circular lock dependency in lockd

2007-09-26T16:22:04Z

The problem is that the garbage collector for the 'host' structures nlm_gc_hosts(), holds nlm_host_mutex while calling down to nlmsvc_mark_resources, which, eventually takes the file->f_mutex. We cannot therefore call nlmsvc_lookup_host() from within nlmsvc_create_block, since the caller will already hold file->f_mutex, so the attempt to grab nlm_host_mutex may deadlock. Fix the problem by calling nlmsvc_lookup_host() outside the file->f_mutex. Signed-off-by: Trond Myklebust Signed-off-by: Linus Torvalds
