From c5266d204a446bea619fa18da8520dceb0a54192 Mon Sep 17 00:00:00 2001
From: Paul Eggert <eggert@cs.ucla.edu>

Subject: [PATCH 2/3] file-has-acl: improve recent NFSv4 support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This fixes a link failure with emacsclient on GNU/Linux. This
program wants file_has_acl but none of the other ACL primitives,
so it doesn’t link acl-internal.o; this way it doesn’t need to
link with -lacl. While I was at it I reviewed the recent changes,
fixed some unlikely overflow bugs, and adjusted to GNU style.
* doc/acl-nfsv4.txt: Remove. Its contents are now in a
comment in lib/file-has-acl.c.
* lib/acl-internal.c, lib/acl-internal.h: Move recent changes
relating to acl_nfs4_nontrivial to lib/file-has-acl.c, so that
there is no trouble linking programs that need only file_has_acl.
* lib/file-has-acl.c (acl_nfs4_nontrivial): Move here from
lib/acl-internal.c, so that we needn't link -lacl in
programs that want only file_has_acl, such as emacsclient.
Do not assume a char buffer is aligned for uint32_t.
Check more carefully for buffer read overrun.
Allow up to 6 ACEs, since other code does; but check
that they’re distinct. Avoid integer overflow.
Use memcmp rather than strncmp to compare memory blocks.
(file_has_acl): Preserve initial errno instead of setting to 0.
Allocate a bit more room for trivial ACL buffer.
Use EINVAL for botchedk NFSv4 ACLs (which shouldn’t happen).
