| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Thanks to Frank Filz for pointing out that we list system.nfs4_acl extended attribute even on filesystems where we don't actually support nfs4_acl. This is inconsistent with the e.g. ext3 POSIX ACL behaviour, and seems to annoy cp. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

This code may be called to process rpc's necessary to perform writes, so there's a potential deadlock whenever we kmalloc() here. After this a couple kmalloc()'s still remain, to be removed soon. This also fixes a rare double-free on error noticed by coverity. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
| * | | | SUNRPC: Ensure rpc_call_async() always calls tk_ops->rpc_release()Trond Myklebust2006-03-213-21/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently this will not happen if we exit before rpc_new_task() was called. Also fix up rpc_run_task() to do the same (for consistency). Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

The solution is to search for requests to wait upon, search for dirty requests, and search for uncommitted requests while holding the nfsi->req_lock The patch also cleans up nfs_sync_inode(), getting rid of the redundant FLUSH_WAIT flag. It turns out that we were always setting it. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

However there is a small race in nfs_readpage_release() whereby the page may be unlocked, and have PG_private set. Fix is to have PG_private set only for the case of writes... Also fix a bug in nfs_clear_page_writeback(): Don't attempt to clear the radix_tree tag if we've already deleted the radix tree entry. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
| * | | | NFSv4: Ensure the callback daemon flushes signalsTrond Myklebust2006-03-201-6/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the callback daemon is signalled, but is unable to exit because it still has users, then we need to flush signals. If not, then svc_recv() can never sleep, and so we hang. If we flush signals, then we also have to be prepared to resend them when we want the thread to exit.

It does so to mark locks granted or reclaimable. This is very suboptimal, because a) lockd needs to poke into locks.c internals, and b) it needs to iterate over all locks in the system for marking locks granted or reclaimable. This patch adds lists for granted and reclaimable locks to the nlm_host structure instead, and adds locks to those. nlmclnt_lock: now adds the lock to h_granted instead of setting the NFS_LCK_GRANTED, still O(1) nlmclnt_mark_reclaim: goes away completely, replaced by a list_splice_init. Complexity reduced from O(locks in the system) to O(1) reclaimer: iterates over h_reclaim now, complexity reduced from O(locks in the system) to O(locks per nlm_host) Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
