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

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.

NFSv4: Implement the fs_locations function call

2006-06-09T13:34:22+00:00

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.

Based on an initial implementation by Jiaying Zhang

[PATCH] nfsd4: fix fh_expire_type

2005-06-24T07:06:28+00:00

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.
