J. Bruce Fields bcaab953b1 nfsd4: remove nfs4_acl_new
This is a not-that-useful kmalloc wrapper.  And I'd like one of the
callers to actually use something other than kmalloc.

J. Bruce Fields ddd1ea5636 nfsd4: use xdr_reserve_space in attribute encoding
This is a cosmetic change for now; no change in behavior.

Note we're just depending on xdr_reserve_space to do the bounds checking
for us, we're not really depending on its adjustment of iovec or xdr_buf
lengths yet, as those are fixed up by as necessary after the fact by
read-link operations and by nfs4svc_encode_compoundres.  However we do
have to update xdr->iov on read-like operations to prevent
xdr_reserve_space from messing with the already-fixed-up length of the
the head.

When the attribute encoding fails partway through we have to undo the
length adjustments made so far.  We do it manually for now, but later
patches will add an xdr_truncate_encode() helper to handle cases like
this.

Linus Torvalds d9894c228b Merge branch 'for-3.14' of git://linux-nfs.org/~bfields/linux
Pull nfsd updates from Bruce Fields:
 - Handle some loose ends from the vfs read delegation support.
   (For example nfsd can stop breaking leases on its own in a
    fewer places where it can now depend on the vfs to.)
 - Make life a little easier for NFSv4-only configurations
   (thanks to Kinglong Mee).
 - Fix some gss-proxy problems (thanks Jeff Layton).
 - miscellaneous bug fixes and cleanup

Christoph Hellwig 4ac7249ea5 nfsd: use get_acl and ->set_acl
Remove the boilerplate code to marshall and unmarhall ACL objects into
xattrs and operate on the posix_acl objects directly.  Also move all
the ACL handling code into nfs?acl.c where it belongs.

J. Bruce Fields 3554116d3a nfsd4: simplify xdr encoding of nfsv4 names
We can simplify the idmapping code if it does its own encoding and
returns nfs errors.
