NFS: Remove the redundant file_open entry from struct nfs_rpc_ops

2008-07-09T16:09:16+00:00

All instances are set to nfs_open(), so we should just remove the redundant
indirection. Ditto for the file_release op

NFS: Add correct bounds checking to NFSv2 locks

2008-07-09T16:08:40+00:00

NFSv2 file locking currently fails the Connectathon tests, because the
calls to the VFS locking code do not return an EINVAL error if the
struct file_lock overflows the 32-bit boundaries.

The problem is due to the fact that we occasionally call helpers from
fs/locks.c in order to avoid RPC calls to the server when we know that a
local process holds the lock. These helpers are, of course, always
64-bit enabled, so EINVAL is not returned in cases when it would if
the call had gone to the NLM code.

For consistency, we therefore add support for a bounds-checking helper.

NFSv4: Only increment the sequence id if the server saw it

2008-04-19T20:53:15+00:00

It is quite possible that the OPEN, CLOSE, LOCK, LOCKU,... compounds fail
before the actual stateful operation has been executed (for instance in the
PUTFH call). There is no way to tell from the overall status result which
operations were executed from the COMPOUND.

The fix is to move incrementing of the sequence id into the XDR layer,
so that we do it as we process the results from the stateful operation.

NFS: Ensure NFSv4 SETCLIENTID send buffer is large enough

2008-01-30T07:05:51+00:00

Ensure that the RPC buffer size specified for NFSv4 SETCLIENTID procedures
matches what we are encoding into the buffer.  See the definition of
struct nfs4_setclientid {} and the encode_setclientid() function.

NFS: Clean up the (commit|read|write)_setup() callback routines

2008-01-30T07:05:32+00:00

Move the common code for setting up the nfs_write_data and nfs_read_data
structures into fs/nfs/read.c, fs/nfs/write.c and fs/nfs/direct.c.

NFS: Fake up 'wcc' attributes to prevent cache invalidation after write

2007-10-09T21:19:15+00:00

NFSv2 and v4 don't offer weak cache consistency attributes on WRITE calls.
In NFSv3, returning wcc data is optional. In all cases, we want to prevent
the client from invalidating our cached data whenever ->write_done()
attempts to update the inode attributes.

NFSv4: Make NFSv4 ACCESS calls return attributes too...

2007-10-09T21:18:38+00:00

It doesn't really make sense to cache an access call without also
revalidating the attributes.

SUNRPC: Clean up the sillyrename code

2007-07-19T19:21:39+00:00

Fix a couple of bugs:
 - Don't rely on the parent dentry still being valid when the call completes.
   Fixes a race with shrink_dcache_for_umount_subtree()

 - Don't remove the file if the filehandle has been labelled as stale.

Fix a couple of inefficiencies
 - Remove the global list of sillyrenamed files. Instead we can cache the
   sillyrename information in the dentry->d_fsdata
 - Move common code from unlink_setup/unlink_done into fs/nfs/unlink.c
