From c1b97d6d896b1f22fdf5d28471ef7859ec840a57 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Fix handling of collating symbols in regexps
[BZ #11561]
* posix/regcomp.c (parse_bracket_exp): When looking up collating
elements compare against the byte sequence of it, not its name.

commit 7a86be6e5f18ba99b25d75c555ce56fe1fcea325
Author: Siddhesh Poyarekar <siddhesh@redhat.com>
Date: Thu Mar 28 11:45:47 2013 +0530
Don't add input group during initgroups_dyn in hesiod
Fixes BZ #15304.
The *initgroups_dyn functions are called with a group argument. This
group gid is usually skipped while populating the grouplist since the
caller adds that group id in advance.
The hesiod initgroups_dyn implementation however adds the group gid to
the list if it does not already exist. While it works fine for the
usual initgroups, it breaks nscd since it calls initgroups_dyn with -1
as the gid (to have all groups included).
