5
6It is effectively used, unexcept for pthread_cond_destroy, where we do
7not want it; see bug 27304. The internal locks do not support a
8process-shared mode.

10This fixes commit dc6cfdc934db9997c33728082d63552b9eee4563 ("nptl:
11Move pthread_cond_destroy implementation into libc").

4Subject: [PATCH] x86: Require full ISA support for x86-64 level marker [BZ #27318]
5
6Since -march=sandybridge enables ISAs in x86-64 ISA level v3, the v3
7marker is set on libc.so. We couldn't set the needed ISA marker to v2
8since this libc won't run on all v2 machines. Technically, the v3 marker
9is correct. But the resulting libc.so won't run on Sandy Brigde, which
10is a v2 machine, even when libc is compiled with -march=sandybridge:
11
12$ ./elf/ld.so ./libc.so
13./libc.so: (p) CPU ISA level is lower than required: needed: 7; got: 3
14
15Instead, we require full ISA support for x86-64 level marker and disable
16x86-64 level marker for -march=sandybridge which enables ISAs between v2
17and v3.

101. Add level1_icache_linesize to struct cpu_features.
112. Initialize level1_icache_linesize by calling handle_intel,
12handle_zhaoxin and handle_amd with _SC_LEVEL1_ICACHE_LINESIZE.

4Subject: [PATCH] nscd: Fix double free in netgroupcache [BZ #27462]
5
6In commit 745664bd798ec8fd50438605948eea594179fba1 a use-after-free
7was fixed, but this led to an occasional double-free. This patch
8tracks the "live" allocation better.

10Tested manually by a third party.
