Sservers that only have NFSv4.1 support the NFS4ERR_MINOR_VERS_MISMATCH error is return on v4.0 mounts. Mapping that error to EPROTONOSUPPORT will cause the mount to back off to v3 instead of failing.

The new commit code fails to copy the verifier into the wb_verf field of _all_ the nfs_page structures; it only copies it into the first entry. The consequence is that most requests end up failing to match in nfs_commit_release. Fix is to copy the verifier into the req->wb_verf field in nfs_write_completion.

This patch only affects mounting through "-t nfs4" since it doesn't set up an nfs version to use in the mount data. The nfs client was trying to mount using NFS v0, causing either a BUG() or a protocol not supported message.

Fix an incorrect use of 'likely()'. The FATTR4_WORD2_MDSTHRESHOLD bit is only expected in NFSv4.1 OPEN calls, and so is actually rather _unlikely_. decode_attr_mdsthreshold needs to clear FATTR4_WORD2_MDSTHRESHOLD from the attribute bitmap after it has decoded the data.

The open recovery code does not need to request a new value for the mdsthreshold, and so does not allocate a struct nfs4_threshold. The problem is that encode_getfattr_open() will still request an mdsthreshold, and so we end up Oopsing in decode_attr_mdsthreshold. This patch fixes encode_getfattr_open so that it doesn't request an mdsthreshold when the caller isn't asking for one. It also fixes decode_attr_mdsthreshold so that it errors if the server returns an mdsthreshold that we didn't ask for (instead of Oopsing).

If a file OPEN is denied due to a share lock, the resulting NFS4ERR_SHARE_DENIED is currently mapped to the default EIO. This patch adds a more appropriate mapping, and brings Linux into line with what Solaris 10 does.

We're already invalidating the data cache, and setting the new change attribute. Since directories don't care about the i_size field, there is no need to be forcing any extra revalidation of the page cache. We do keep the NFS_INO_INVALID_ATTR flag, in order to force an attribute cache revalidation on stat() calls since we do not update the mtime and ctime fields.

If the EXCHGID4_FLAG_CONFIRMED_R flag is set, the client is in theory supposed to already know the correct value of the seqid, in which case RFC5661 states that it should ignore the value returned. Also ensure that if the sanity check in nfs4_check_cl_exchange_flags fails, then we must not change the nfs_client fields. Finally, clean up the code: we don't need to retest the value of 'status' unless it can change. Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

Apparently the patch "NFS: Always use the same SETCLIENTID boot verifier" is tickling a Linux nfs server bug, and causing a regression: the server can get into a situation where it keeps replying NFS4ERR_SEQ_MISORDERED to our CREATE_SESSION request even when we are sending the correct sequence ID.

Since the struct nfs_client gets added to the global nfs_client_list before it is initialised, it is possible that rpc_pipefs_event can end up trying to create idmapper entries on such a thing. The solution is to have the mount notification wait for the initialisation of each nfs_client to complete, and then to skip any entries for which the it failed.

Session initialisation is not complete until the lease manager has run. We need to ensure that both nfs4_init_session and nfs4_init_ds_session do so, and that they check for any resulting errors in clp->cl_cons_state.

Clean up: Continue to rationalize the locking in nfs_get_client() by moving the logic that handles the case where a matching server IP address is not found. When we support server trunking detection, client initialization may return a different nfs_client struct than was passed to it. Change the synopsis of the init_client methods to return an nfs_client. The client initialization logic in nfs_get_client() is not much more than a wrapper around ->init_client. It's simpler to keep the little bits of error handling in the version-specific init_client methods. No behavior change is expected.
