-Subject: [PATCH] librt: fix NULL pointer dereference (bug 28213)
-
-Helper thread frees copied attribute on NOTIFY_REMOVED message
-received from the OS kernel.  Unfortunately, it fails to check whether
-copied attribute actually exists (data.attr != NULL).  This worked
-earlier because free() checks passed pointer before actually
-attempting to release corresponding memory.  But
-__pthread_attr_destroy assumes pointer is not NULL.
-
-So passing NULL pointer to __pthread_attr_destroy will result in
-segmentation fault.  This scenario is possible if
-notification->sigev_notify_attributes == NULL (which means default
-thread attributes should be used).

-Subject: [PATCH] librt: add test (bug 28213)
-
-This test implements following logic:
-1) Create POSIX message queue.
-   Register a notification with mq_notify (using NULL attributes).
-   Then immediately unregister the notification with mq_notify.
-   Helper thread in a vulnerable version of glibc
-   should cause NULL pointer dereference after these steps.
-2) Once again, register the same notification.
-   Try to send a dummy message.
-   Test is considered successfulif the dummy message
-   is successfully received by the callback function.

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

-Subject: [PATCH] x86: Handle _SC_LEVEL1_ICACHE_LINESIZE [BZ #27444]
-
-    x86: Move x86 processor cache info to cpu_features
-
-missed _SC_LEVEL1_ICACHE_LINESIZE.
-
-1. Add level1_icache_linesize to struct cpu_features.
-2. Initialize level1_icache_linesize by calling handle_intel,
-handle_zhaoxin and handle_amd with _SC_LEVEL1_ICACHE_LINESIZE.
-3. Return level1_icache_linesize for _SC_LEVEL1_ICACHE_LINESIZE.

+Since the full ISA set used in an ELF binary is unknown to compiler,
+an x86-64 ISA level marker indicates the minimum, not maximum, ISA set
+required to run such an ELF binary.  We never guarantee a library with
+an x86-64 ISA level v3 marker doesn't contain other ISAs beyond x86-64
+ISA level v3, like AVX VNNI.  We check the x86-64 ISA level marker for
+the minimum ISA set.  Since -march=sandybridge enables only some ISAs
+in x86-64 ISA level v3, we should set the needed ISA marker to v2.
+Otherwise, libc is compiled with -march=sandybridge will fail to run on
+Sandy Bridge:
+
+$ ./elf/ld.so ./libc.so
+./libc.so: (p) CPU ISA level is lower than required: needed: 7; got: 3
+
+Set the minimum, instead of maximum, x86-64 ISA level marker should have
+no impact on the b-hwcaps directory assignment logic in ldconfig nor
+ld.so.

-
-In commit 745664bd798ec8fd50438605948eea594179fba1 a use-after-free
-was fixed, but this led to an occasional double-free.  This patch
-tracks the "live" allocation better.
-
-Tested manually by a third party.

-Subject: [PATCH] Fix use of __pthread_attr_copy in mq_notify (bug 27896)
-
-__pthread_attr_copy can fail and does not initialize the attribute
-structure in that case.
-
-If __pthread_attr_copy is never called and there is no allocated
-attribute, pthread_attr_destroy should not be called, otherwise
-there is a null pointer dereference in rt/tst-mqueue6.
-
-Fixes commit 42d359350510506b87101cf77202fefcbfc790cb
