the server can indicate a number of error conditions by setting the appropriate bits in the SEQUENCE operation.

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.

refactor the nfs4 server lock code to use last_byte_offset to compute the last byte covered by the lock.

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.

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’ on 64-bit systems Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

We're returning NFS4_FH_NOEXPIRE_WITH_OPEN | NFS4_FH_VOL_RENAME for the fh_expire_type attribute. This is incorrect: 1. The spec actually only allows NOEXPIRE_WITH_OPEN when VOLATILE_ANY is also set. 2. Filehandles for open files can expire, if the file is removed and there is a reboot. 3. Filehandles are only volatile on rename in the nosubtree check case. Unfortunately, there's no way to indicate that we only expire on remove. So our only choice is FH4_VOLATILE_ANY. Although it's redundant, we also set FH4_VOL_RENAME in the subtree check case, since subtreecheck does actually cause problems in practice and it seems possibly useful to give clients some way to distinguish that case.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
