Greg Banks c9ce228306 [PATCH] Fix a free-wrong-pointer bug in nfs/acl server.
Due to type confusion, when an nfsacl verison 2 'ACCESS' request
finishes and tries to clean up, it calls fh_put on entiredly the
wrong thing and this can cause an oops.

Jesper Juhl cb65a5ba3d [PATCH] NFS2: Calculate 'w' a bit later in nfsaclsvc_encode_getaclres()
NFS2: Calculate 'w' a bit later in nfsaclsvc_encode_getaclres()
      This is a small performance optimization since we can return before
      needing 'w'. It also saves a few bytes of .text :
      Before:
           text    data     bss     dec     hex filename
           2406     212       0    2618     a3a fs/nfsd/nfs2acl.o
      After:
           text    data     bss     dec     hex filename
           2400     212       0    2612     a34 fs/nfsd/nfs2acl.o

Olaf Kirch bc5fea4299 [PATCH] knfsd: register all RPC programs with portmapper by default
The NFSACL patches introduced support for multiple RPC services listening on
the same transport.  However, only the first of these services was registered
with portmapper.  This was perfectly fine for nfsacl, as you traditionally do
not want these to show up in a portmapper listing.

The patch below changes the default behavior to always register all services
listening on a given transport, but retains the old behavior for nfsacl
services.

NeilBrown 4452435948 [PATCH] knfsd: Replace two page lists in struct svc_rqst with one
We are planning to increase RPCSVC_MAXPAGES from about 8 to about 256.  This
means we need to be a bit careful about arrays of size RPCSVC_MAXPAGES.

struct svc_rqst contains two such arrays.  However the there are never more
that RPCSVC_MAXPAGES pages in the two arrays together, so only one array is
needed.

The two arrays are for the pages holding the request, and the pages holding
the reply.  Instead of two arrays, we can simply keep an index into where the
first reply page is.

This patch also removes a number of small inline functions that probably
server to obscure what is going on rather than clarify it, and opencode the
needed functionality.

Also remove the 'rq_restailpage' variable as it is *always* 0.  i.e.  if the
response 'xdr' structure has a non-empty tail it is always in the same pages
as the head.

 check counters are initilised and incr properly
 check for consistant usage of ++ etc
 maybe extra some inlines for common approach
 general review

Andreas Gruenbacher b7964c3d88 [PATCH] nfsd: check for read-only exports before setting acls
We must check for MAY_SATTR before setting acls, which includes checking
for read-only exports: the lower-level setxattr operation that
eventually sets the acl cannot check export-level restrictions.

Bug reported by Martin Walter <mawa@uni-freiburg.de>.

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.
