-Subject: [PATCH] [BZ #22342] Fix netgroup cache keys.
-
-Unlike other nscd caches, the netgroup cache contains two types of
-records - those for "iterate through a netgroup" (i.e. setnetgrent())
-and those for "is this user in this netgroup" (i.e. innetgr()),
-i.e. full and partial records.  The timeout code assumes these records
-have the same key for the group name, so that the collection of records
-that is "this netgroup" can be expired as a unit.
-
-However, the keys are not the same, as the in-netgroup key is generated
-by nscd rather than being passed to it from elsewhere, and is generated
-without the trailing NUL.  All other keys have the trailing NUL, and as
-noted in the linked BZ, debug statements confirm that two keys for the
-same netgroup are added to the cache with two different lengths.
-
-The result of this is that as records in the cache expire, the purge
-code only cleans out one of the two types of entries, resulting in
-stale, possibly incorrect, and possibly inconsistent cache data.
-
-The patch simply includes the existing NUL in the computation for the
-key length ('key' points to the char after the NUL, and 'group' to the
-first char of the group, so 'key-group' includes the first char to the
-NUL, inclusive).
-
-	[BZ #22342]
-	* nscd/netgroupcache.c (addinnetgrX): Include trailing NUL in
-	key value.

-Subject: [PATCH] i386: Fix i386 sigaction sa_restorer initialization
- (BZ#21269)
-
-This patch fixes the i386 sa_restorer field initialization for sigaction
-syscall for kernel with vDSO.  As described in bug report, i386 Linux
-(and compat on x86_64) interprets SA_RESTORER clear with nonzero
-sa_restorer as a request for stack switching if the SS segment is 'funny'.
-This means that anything that tries to mix glibc's signal handling with
-segmentation (for instance through modify_ldt syscall) is randomly broken
-depending on what values lands in sa_restorer.
-
-The testcase added  is based on Linux test tools/testing/selftests/x86/ldt_gdt.c,
-more specifically in do_multicpu_tests function.  The main changes are:
-
-  - C11 atomics instead of plain access.
-
-  - Remove x86_64 support which simplifies the syscall handling and fallbacks.
-
-  - Replicate only the test required to trigger the issue.
-
-Checked on i686-linux-gnu.
-
-	[BZ #21269]
-	* sysdeps/unix/sysv/linux/i386/Makefile (tests): Add tst-bz21269.
-	* sysdeps/unix/sysv/linux/i386/sigaction.c (SET_SA_RESTORER): Clear
-	sa_restorer for vDSO case.
-	* sysdeps/unix/sysv/linux/i386/tst-bz21269.c: New file.
