NFSv4: Add support for the RELEASE_LOCKOWNER operation

2010-07-30T18:46:10+00:00

This is needed by NFSv4.0 servers in order to keep the number of locking
stateids at a manageable level.

nfs41: RECLAIM_COMPLETE XDR functionality

2009-12-05T21:08:40+00:00

XDR encoding and decoding for RECLAIM_COMPLETE.  Implements the necessary
encoding to indicate reclaim complete for the entire client.  In the future,
it can be extended to provide reclaim complete functionality for a single
file system after migration.

nfs41: check SEQUENCE status flag

2009-12-05T18:46:14+00:00

the server can indicate a number of error conditions by setting the
appropriate bits in the SEQUENCE operation. The client re-establishes
state with the server when it receives one of those, with the action
depending on the specific case.

NFS: Allow the "nfs" file system type to support NFSv4

2009-09-08T23:50:03+00:00

When mounting an "nfs" type file system, recognize "v4," "vers=4," or
"nfsvers=4" mount options, and convert the file system to "nfs4" under
the covers.

nfs41: create_session operation

2009-06-17T19:24:34+00:00

Implement the create_session operation conforming to
http://tools.ietf.org/html/draft-ietf-nfsv4-minorversion1-26

Set the real fore channel max operations to preserve server resources.
Note: If the server returns < NFS4_MAX_OPS, the client will very soon
get an NFS4ERR_TOO_MANY_OPS. A later patch will handle this.

Set the max_rqst_sz and max_resp_sz to PAGE_SIZE - we preallocate the buffers.

Set the back channel max_resp_sz_cached to zero to force the client to
always set csa_cachethis to FALSE because the current implementation
of the back channel DRC only supports caching the CB_SEQUENCE operation.

The client back channel server supports one slot, and desires 2 operations
per compound.

nfs41: exchange_id operation

2009-06-17T19:23:57+00:00

Implement the exchange_id operation conforming to
http://tools.ietf.org/html/draft-ietf-nfsv4-minorversion1-26

Unlike NFSv4.0, NFSv4.1 requires machine credentials. RPC_AUTH_GSS machine
credentials will be passed into the kernel at mount time to be available for
the exchange_id operation.

RPC_AUTH_UNIX root mounts can use the UNIX root credential. Store the root
credential in the nfs_client struct.

Without a credential, NFSv4.1 state renewal fails.

nfsd41: CREATE_EXCLUSIVE4_1

Implement the CREATE_EXCLUSIVE4_1 open mode conforming to
http://tools.ietf.org/html/draft-ietf-nfsv4-minorversion1-26

This mode allows the client to atomically create a file
if it doesn't exist while setting some of its attributes.

It must be implemented if the server supports persistent
reply cache and/or pnfs.
