+Subject: [PATCH] Always enable pointer guard [BZ #18928]
+
+Honoring the LD_POINTER_GUARD environment variable in AT_SECURE mode
+has security implications.  This commit enables pointer guard
+unconditionally, and the environment variable is now ignored.
+
+        [BZ #18928]
+        * sysdeps/generic/ldsodefs.h (struct rtld_global_ro): Remove
+        _dl_pointer_guard member.
+        * elf/rtld.c (_rtld_global_ro): Remove _dl_pointer_guard
+        initializer.
+        (security_init): Always set up pointer guard.
+        (process_envvars): Do not process LD_POINTER_GUARD.
+
+Upstream-Status: Backport
+CVE: CVE-2015-8777
+[Yocto # 8980]

+Subject: [PATCH] Refactor strtod parsing of NaN payloads.
+
+The nan* functions handle their string argument by constructing a
+NAN(...) string on the stack as a VLA and passing it to strtod
+functions.
+
+This approach has problems discussed in bug 16961 and bug 16962: the
+stack usage is unbounded, and it gives incorrect results in certain
+cases where the argument is not a valid n-char-sequence.
+
+The natural fix for both issues is to refactor the NaN payload parsing
+out of strtod into a separate function that the nan* functions can
+call directly, so that no temporary string needs constructing on the
+stack at all.  This patch does that refactoring in preparation for
+fixing those bugs (but without actually using the new functions from
+nan* - which will also require exporting them from libc at version
+GLIBC_PRIVATE).  This patch is not intended to change any user-visible
+behavior, so no tests are added (fixes for the above bugs will of
+course add tests for them).
+
+This patch builds on my recent fixes for strtol and strtod issues in
+Turkish locales.  Given those fixes, the parsing of NaN payloads is
+locale-independent; thus, the new functions do not need to take a
+locale_t argument.
+
+Tested for x86_64, x86, mips64 and powerpc.
