-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.

-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.
