* NFSv4: Fix a cache validation bug which causes getcwd() to return ENOENTTrond Myklebust2009-11-11
| | | | | | | | | | | | | | | | | | Changeset a65318bf3afc93ce49227e849d213799b072c5fd (NFSv4: Simplify some cache consistency post-op GETATTRs) incorrectly changed the getattr bitmap for readdir(). This causes the readdir() function to fail to return a fileid/inode number, which again exposed a bug in the NFS readdir code that causes spurious ENOENT errors to appear in applications (see http://bugzilla.kernel.org/show_bug.cgi?id=14541). The immediate band aid is to revert the incorrect bitmap change, but more long term, we should change the NFS readdir code to cope with the fact that NFSv4 servers are not required to support fileids/inode numbers.

* NFSv4: Fix a bug when the server returns NFS4ERR_RESOURCETrond Myklebust2009-10-23
| | | | | | | | | | | | | RFC 3530 states that when we recieve the error NFS4ERR_RESOURCE, we are not supposed to bump the sequence number on OPEN, LOCK, LOCKU, CLOSE, etc operations. The problem is that we map that error into EREMOTEIO in the XDR layer, and so the NFSv4 middle-layer routines like seqid_mutating_err(), and nfs_increment_seqid() don't recognise it. The fix is to defer the mapping until after the middle layers have processed the error. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* nfs: Panic when commit failsTerry Loftin2009-10-23
| | | | | | | | | | | | | | | | Actually pass the NFS_FILE_SYNC option to the server to avoid a Panic in nfs_direct_write_complete() when a commit fails. At the end of an nfs write, if the nfs commit fails, all the writes will be rescheduled. They are supposed to be rescheduled as NFS_FILE_SYNC writes, but the rpc_task structure is not completely intialized and so the option is not passed. When the rescheduled writes complete, the return indicates that they are NFS_UNSTABLE and we try to do another commit. This leads to a Panic because the commit data structure pointer was set to null in the initial (failed) commit attempt.

* NFSv4: Kill nfs4_renewd_prepare_shutdown()Trond Myklebust2009-10-08
| | | | | | | | | | | | The NFSv4 renew daemon is shared between all active super blocks that refer to a particular NFS server, so it is wrong to be shutting it down in nfs4_kill_super every time a super block is destroyed. This patch therefore kills nfs4_renewd_prepare_shutdown altogether, and leaves it up to nfs4_shutdown_client() to also shut down the renew daemon by means of the existing call to nfs4_kill_renewd().

* nfs: Avoid overrun when copying client IP address stringBen Hutchings2009-10-06
| | | | | | | | | | | As seen in <http://bugs.debian.org/549002>, nfs4_init_client() can overrun the source string when copying the client IP address from nfs_parsed_mount_data::client_address to nfs_client::cl_ipaddr. Since these are both treated as null-terminated strings elsewhere, the copy should be done with strlcpy() not memcpy().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some releases of Linux rpc.mountd (nfs-utils 1.1.4 and later) return an empty auth flavor list if no sec= was specified for the export. This is notably broken server behavior. The new auth flavor list checking added in a recent commit rejects this case. The OpenSolaris client does too. The broken mountd implementation is already widely deployed. To avoid a behavioral regression, the kernel's mount client skips flavor checking (ie reverts to the pre-2.6.32 behavior) if mountd returns an empty flavor list.
