nfsd41: CREATE_EXCLUSIVE4_1

2009-04-04T00:41:23+00:00

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.

nfs41: common protocol definitions

2009-04-04T00:41:12+00:00

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_offset

2009-01-07T22:38:31+00:00

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_* defines

2008-06-23T17:02:48+00:00

These flag bits aren't used by either the protocol or our
implementation, so I don't know why they were here.

Thanks to Johann Dahm for running across these.

NFS4: on a O_EXCL OPEN make sure SETATTR sets the fields holding the verifier

2007-07-11T03:40:25+00:00

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.c

2007-05-14T23:33:45+00:00

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

[PATCH] knfsd: nfsd4: represent nfsv4 acl with array instead of linked list

2007-02-16T16:14:01+00:00

Simplify the memory management and code a bit by representing acls with an
array instead of a linked list.

[PATCH] knfsd: nfsd4: add per-operation server stats

2006-07-10T20:24:27+00:00

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.
