* NFS: rsize and wsize settings ignored on v4 mountsChuck Lever2010-05-121-0/+2
| | | | | | | | | | | | | | | | | | commit 356e76b855bdbfd8d1c5e75bcf0c6bf0dfe83496 upstream. NFSv4 mounts ignore the rsize and wsize mount options, and always use the default transfer size for both. This seems to be because all NFSv4 mounts are now cloned, and the cloning logic doesn't copy the rsize and wsize settings from the parent nfs_server. I tested Fedora's 2.6.32.11-99 and it seems to have this problem as well, so I'm guessing that .33, .32, and perhaps older kernels have this issue as well.

* nfs d_revalidate() is too trigger-happy with d_drop()Al Viro2010-05-121-0/+2
| | | | | | | | | | | | | | | | | | commit d9e80b7de91db05c1c4d2e5ebbfd70b3b3ba0e0f upstream. If dentry found stale happens to be a root of disconnected tree, we can't d_drop() it; its d_hash is actually part of s_anon and d_drop() would simply hide it from shrink_dcache_for_umount(), leading to all sorts of fun, including busy inodes on umount and oopsen after that. Bug had been there since at least 2006 (commit c636eb already has it), so it's definitely -stable fodder.

* NFSv4: fix delegated lockingTrond Myklebust2010-04-262-2/+5
| | | | | | | | | | | | | | | | | | | | | | commit 0df5dd4aae211edeeeb84f7f84f6d093406d7c22 upstream. Arnaud Giersch reports that NFSv4 locking is broken when we hold a delegation since commit 8e469ebd6dc32cbaf620e134d79f740bf0ebab79 (NFSv4: Don't allow posix locking against servers that don't support it). According to Arnaud, the lock succeeds the first time he opens the file (since we cannot do a delegated open) but then fails after we start using delegated opens. The following patch fixes it by ensuring that locking behaviour is governed by a per-filesystem capability flag that is initially set, but gets cleared if the server ever returns an OPEN without the NFS4_OPEN_RESULT_LOCKTYPE_POSIX flag being set.

* NFS: Too many GETATTR and ACCESS calls after direct I/OChuck Lever2010-02-151-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cached read and write paths initialize fattr->time_start in their setup procedures. The value of fattr->time_start is propagated to read_cache_jiffies by nfs_update_inode(). Subsequent calls to nfs_attribute_timeout() will then use a good time stamp when computing the attribute cache timeout, and squelch unneeded GETATTR calls. Since the direct I/O paths erroneously leave the inode's fattr->time_start field set to zero, read_cache_jiffies for that inode is set to zero after any direct read or write operation. This triggers an otw GETATTR or ACCESS call to update the file's attribute and access caches properly, even when the NFS READ or WRITE replies have usable post-op attributes. Make sure the direct read and write setup code performs the same fattr initialization as the cached I/O paths to prevent unnecessary GETATTR calls. This was likely introduced by commit 0e574af1 in 2.6.15, which appears to add new nfs_fattr_init() call sites in the cached read and write paths, but not in the equivalent places in fs/nfs/direct.c. A subsequent commit in the same series, 33801147, introduces the fattr->time_start field. Interestingly, the direct write reschedule path already has a call to nfs_fattr_init() in the right place.

* NFS: Fix an Oops when truncating a fileTrond Myklebust2010-02-031-8/+9
| | | | | | | | | | | | | | The VM/VFS does not allow mapping->a_ops->invalidatepage() to fail. Unfortunately, nfs_wb_page_cancel() may fail if a fatal signal occurs. Since the NFS code assumes that the page stays mapped for as long as the writeback is active, we can end up Oopsing (among other things). The only safe fix here is to convert nfs_wait_on_request(), so as to make it uninterruptible (as is already the case with wait_on_page_writeback()).

The calls to nfs4_end_drain_session() from the main loop in nfs4_state_manager() Oops due to the lack of an NFSv4.1 session when running NFSv4.0. The fix is to move those two calls back into nfs41_init_clientid() and nfs4_reset_session(). The calls to nfs4_end_drain_session() that remain inside nfs4_state_manager() are safe, since the NFSv4.0 code will never set the NFS4CLNT_SESSION_DRAINING bit.

Also fix up the locking around the page->private transfer, so that we ensure that calls to nfs_page_find_request() don't end up racing. Finally, fix up a double free bug: nfs_unlock_request() already calls nfs_release_request() for us...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The NFSv4.1 spec indicates RECLAIM_COMPLETE is to be issued whenever a client establishes a new client id, not only after detecting the server has rebooted. Set the NFS4CLNT_RECLAIM_REBOOT bit after every new client id has been established. This enables us to issue RECLAIM_COMPLETE during the wrap up of the NFS4CLNT_RECLAIM_REBOOT state.

| | * | | NFSv41: Fix a potential state leakage when restarting nfs4_close_prepareTrond Myklebust2009-12-081-17/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, if the call to nfs4_setup_sequence() in nfs4_close_prepare fails, any later retries will fail to launch an RPC call, due to the fact that the &state->flags will have been cleared. Ditto if nfs4_close_done() triggers a call to the NFSv4.1 version of nfs_restart_rpc(). We therefore move the actual clearing of the state->flags to nfs4_close_done(), when we know that the RPC call was successful. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
