* nfsd41: CREATE_EXCLUSIVE4_1Benny Halevy2009-04-031-1/+7
| | | | | | | | | | | | | | 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. Signed-off-by: Benny Halevy <bhalevy@panasas.com> Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>

| | | | | | | | | | | | | | | | | | | | | | | Define all NFSv4.1 common operation and error code constants. Note that some of the definitions are used by both the nfs41 client and the server code. This patch is duplicated in the nfs41 and nfsd41 sessions patchset.

* nfsd: last_byte_offsetBenny Halevy2009-01-071-0/+2
| | | | | | | | | | | | refactor the nfs4 server lock code to use last_byte_offset to compute the last byte covered by the lock. Check for overflow so that the last byte is set to NFS4_MAX_UINT64 if offset + len wraps around. Also, use NFS4_MAX_UINT64 for ~(u64)0 where appropriate.

* nfsd: remove three unused NFS4_ACE_* definesJ. Bruce Fields2008-06-231-3/+0

* NFS4: on a O_EXCL OPEN make sure SETATTR sets the fields holding the verifierJeff Layton2007-07-101-0/+1
| | | | | | | | | | | | | | | | | 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.

* NFS4: Fix incorrect use of sizeof() in fs/nfs/nfs4xdr.cTrond Myklebust2007-05-141-1/+2
| | | | | | | | | | | | | | 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: Trond Myklebust <Trond.Myklebust@netapp.com>

| | | | | | | | | | | | Add an nfs4 operations count array to nfsd_stats structure. The count is incremented in nfsd4_proc_compound() where all the operations are handled by the nfsv4 server. This count of individual nfsv4 operations is also entered into /proc filesystem.

* | NFSv4: Implement the fs_locations function callTrond Myklebust2006-06-091-0/+1
|/ | | | | | | | | | | NFSv4 allows for the fact that filesystems may be replicated across several servers or that they may be migrated to a backup server in case of failure of the primary server. fs_locations is an NFSv4 operation for retrieving information about the location of migrated and/or replicated filesystems.

* [PATCH] nfsd4: fix fh_expire_typeNeilBrown2005-06-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | 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. Fix a mispelled #define while we're at it. Signed-off-by: J.

* Linux-2.6.12-rc2Linus Torvalds2005-04-161-0/+394
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!
