NeilBrown 496400014f [PATCH] nfsd4: fix fh_expire_type
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.

NeilBrown 0dd3c19212 [PATCH] nfsd4: support CLAIM_DELEGATE_CUR
Add OPEN claim type NFS4_OPEN_CLAIM_DELEGATE_CUR to nfsd4_open().

A delegation stateid and a name are provided.  OPEN with O_CREAT is not legal
with this claim type; otherwise, use the NFS4_OPEN_CLAIM_NULL code path to
lookup the filename to be opened.

NeilBrown c44c5eeb2c [PATCH] nfsd4: add open state code for CLAIM_DELEGATE_CUR
State logic for OPEN with claim type CLAIM_DELEGATE_CUR, which the NFSv4
client uses to report local OPENs on a delegated file back to the NFSv4
server.

nfs4_check_deleg() performs input delegation stateid lookup and sanity check.

NeilBrown 567d98292e [PATCH] nfsd4: don't reopen for delegated client
We don't really need to be doing a separate open for every stateid.  And in
the case of an open from a client that already has a delegation on a file, it
unnecessarily results in a delegation recall.

Andreas Gruenbacher a257cdd0e2 [PATCH] NFSD: Add server support for NFSv3 ACLs.
This adds functions for encoding and decoding POSIX ACLs for the NFSACL
 protocol extension, and the GETACL and SETACL RPCs.  The implementation is
 compatible with NFSACL in Solaris.

NeilBrown c907132d53 [PATCH] nfsd4: fix struct file leak
We were failing to close on an error path, resulting in a leak of struct files
which could take a v4 server down fairly quickly....  So call
nfs4_close_delegation instead of just open-coding parts of it.

Simplify the cleanup on delegation failure while we're at it.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
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!
