FREE_STATEID is used to tell the server that we want to free a stateid
that no longer has any locks associated with it. This allows the client
to reclaim locks without encountering edge conditions documented in
section 8.4.3 of RFC 5661.Signed-off-by: Bryan Schumaker

This patch adds in the xdr for doing a TEST_STATEID call with a single

If the client is using NFS v4.1, then we can use SECINFO_NO_NAME to find
the secflavor for the initial mount. If the server doesn't support
SECINFO_NO_NAME then I fall back on the "guess and check" method used
for v4.0 mounts.Signed-off-by: Bryan Schumaker

Add the ability to actually send LAYOUTGET and GETDEVICEINFO. This also adds
in the machinery to handle layout state and the deviceid cache. Note that
GETDEVICEINFO is not called directly by the generic layer. Instead it
is called by the drivers while parsing the LAYOUTGET opaque data in response
to an unknown device id embedded therein. RFC 5661 only encodes
device ids within the driver-specific opaque data.Signed-off-by: Andy Adamson

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

The Linux NFS4 client simply skips over the bitmask in an O_EXCL open
call and so it doesn't bother to reset any fields that may be holding
the verifier. This patch has us save the first two words of the bitmask
(which is all the current client has #defines for). The client then
later checks this bitmask and turns on the appropriate flags in the
sattr->ia_verify field for the following SETATTR call.This patch only currently checks to see if the server used the atime
and mtime slots for the verifier (which is what the Linux server uses
for this). I'm not sure of what other fields the server could
reasonably use, but adding checks for others should be trivial.Signed-off-by: Jeff Layton

The XDR code should not depend on the physical allocation size of
structures like nfs4_stateid and nfs4_verifier since those may have to
change at some future date. We therefore replace all uses of
sizeof() with constants like NFS4_VERIFIER_SIZE and NFS4_STATEID_SIZE.This also has the side-effect of fixing some warnings of the type
format ‘%u’ expects type ‘unsigned int’, but argument X has type
‘long unsigned int’
