Single thread optimization is valid if at thread creation time the
optimization can be disabled. This is in principle true for all
stream objects that user code can access (and thus needs locking),
using the same internal list as fflush(0) uses. However in glibc
open_memstream is not on that list (BZ 21735) so the optimization
has to be disabled.
* libio/memstream.c (__open_memstream): Set _IO_FLAGS2_NEED_LOCK.
* libio/wmemstream.c (open_wmemstream): Likewise.
* nptl/tst-memstream.c: New.

Bug 21694 - Current Glibc Locale Does Not Support Tok-Pisin and Fiji Hindi Locale
There is bug report that ld.so in GLIBC 2.24 built by Binutils 2.29 will crash
on arm-linux-gnueabihf. This is confirmed, and the details is at:
https://sourceware.org/bugzilla/show_bug.cgi?id=21725.
As analyzed in the PR, the old code was with the assumption that assembler
won't set bit0 of thumb function address if it comes from PC-relative
instructions and the calculation can be finished during assembling. This
assumption however does not hold after PR gas/21458.
* sysdeps/arm/dl-machine.h (elf_machine_load_address): Also strip bit 0
of pcrel_address under Thumb mode.
Compile tst-ssp-1.c with -fstack-protector-all in case the the stack
protector heuristics do not instrument a thirty-byte array.
* debug/Makefile (CFLAGS-tst-ssp-1.c): Set to
-fstack-protector-all.
On powerpc64le, the compilation of the files related to float128 support
requires the option -mfloat128 to be passed to gcc. However, not all
possible object suffixes were covered in the Makefile. This patch uses
$(all-object-suffixes) in all remaining rules.
Tested for powerpc64le.
* sysdeps/powerpc/powerpc64le/Makefile: Use $(all-object-suffixes)
to iterate over all possible object suffixes. Add a comment
explaining the use of sysdep-CFLAGS instead of CFLAGS.
__stack_chk_fail is called on corrupted stack. Stack backtrace is very
unreliable against corrupted stack. __libc_message is changed to accept
enum __libc_message_action and call BEFORE_ABORT only if action includes
do_backtrace. __fortify_fail_abort is added to avoid backtrace from
__stack_chk_fail.
[BZ #12189]
* debug/Makefile (CFLAGS-tst-ssp-1.c): New.
(tests): Add tst-ssp-1 if -fstack-protector works.
* debug/fortify_fail.c: Include <stdbool.h>.
(_fortify_fail_abort): New function.
(__fortify_fail): Call _fortify_fail_abort.
(__fortify_fail_abort): Add a hidden definition.
* debug/stack_chk_fail.c: Include <stdbool.h>.
(__stack_chk_fail): Call __fortify_fail_abort, instead of
__fortify_fail.
* debug/tst-ssp-1.c: New file.
* include/stdio.h (__libc_message_action): New enum.
(__libc_message): Replace int with enum __libc_message_action.
(__fortify_fail_abort): New hidden prototype.
* malloc/malloc.c (malloc_printerr): Update __libc_message calls.
* sysdeps/posix/libc_fatal.c (__libc_message): Replace int
with enum __libc_message_action. Call BEFORE_ABORT only if
action includes do_backtrace.
(__libc_fatal): Update __libc_message call.
Linux 4.12 (b745fafaf70c0a98a2e1e7ac8cb14542889ceb0e) adds a new
p{read,write}v2 flag RWF_NOWAIT. This patch adds it for linux
uio-ext.h header.
Checked on x86_64-linux-gnu (on a 4.10 kernel).
[BZ #21738]
* manual/llio.texi (RWF_NOWAIT): New item.
* misc/tst-preadvwritev2-common.c (do_test_with_invalid_flags):
Add RWF_NOWAIT check.
* sysdeps/unix/sysv/linux/bits/uio-ext.h (RWF_NOWAIT): New flag.
The request PTRACE_SINGLEBLOCK was introduced in Linux 3.15. Thus the ptrace call
will fail on older kernels.
Thus the test is now testing PTRACE_SINGLEBLOCK with data argument pointing to a
buffer on stack which is assumed to fail. If the request would be interpreted as
PTRACE_GETREGS, then the ptrace call will not fail and the regs are written to buf.
If we run with a kernel with support for PTRACE_SINGLEBLOCK a ptrace call with
data=NULL, returns zero with no error. If we run with a kernel without support for
PTRACE_SINGLEBLOCK a ptrace call with data=NULL reports an error.
In the latter case, the test is just continuing with PTRACE_CONT.
ChangeLog:
* sysdeps/unix/sysv/linux/s390/tst-ptrace-singleblock.c:
Support running on kernels without PTRACE_SINGLEBLOCK.
Since _dl_resolve_conflicts is only used in elf/rtld.c, don't include
it in libc.a.
[BZ #21742]
* elf/Makefile (dl-routines): Move dl-conflict to ...
(rtld-routines): Here.
Since there are no multiarch versions of memmove_chk and memset_chk,
test multiarch versions of memmove_chk and memset_chk only in libc.so.
[BZ #21741]
* sysdeps/x86_64/multiarch/ifunc-impl-list.c
(__libc_ifunc_impl_list): Test memmove_chk and memset_chk only
in libc.so.
