2017-07-12Added Samoan language locale for SamoaAkhilesh Kumar
[BZ #21710] * locales/sm_WS: New file. * SUPPORTED: Add sm_WS/UTF-8.
2017-07-11powerpc64le: Iterate over all object suffixes when appending -mfloat128Gabriel F. T. Gomes
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.
2017-07-11Avoid backtrace from __stack_chk_fail [BZ #12189]H.J. Lu
__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.
2017-07-11posix: Add p{read,write}v2 RWF_NOWAIT flag (BZ#21738)Adhemerval Zanella
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.

2017-07-11S390: Fix tst-ptrace-singleblock if kernel does not support PTRACE_SINGLEBLOCK.Stefan Liebler
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.

2017-07-06Increase some test timeouts.Joseph Myers
This patch increases the timeouts for some tests that I've seen timing out on slow systems in my 2.26 release testing. (In the case of tst-tsearch.c, increasing the timeout means removing a setting of 10 that was put there before the default timeout was increased to 20 seconds, so putting the default into effect.) * iconvdata/tst-loading.c (TIMEOUT): Define to 30. * misc/tst-tsearch.c (TIMEOUT): Remove. * nptl/tst-create-detached.c (TIMEOUT): Define to 100. * nptl/tst-robust-fork.c (TIMEOUT): Likewise. * nptl/tst-rwlock19.c (TIMEOUT): Likewise. * string/tst-cmp.c (TIMEOUT): Define to 600.
2017-07-06Arabic scripts: More fixes after the recent import.Rafal Luzynski
After the recent import of month names from CLDRv31 (bug 21217, commit c853f14) more imports are also needed, mostly abbreviated month names. This patch also updates May (full month name) in ps_AF which was skipped in the previous patch. Incidentally, this import fixes bug 17225 (ar_SY) and partially bug 19066 (ar_SA). CLDR currently has a bug in the full month name for October for ar_IQ, see http://unicode.org/cldr/trac/ticket/10460 * localedata/locales/ar_DZ (abmon): Full import from CLDR, abmon is no longer abbreviated. * localedata/locales/ar_IQ (abmon): Likewise. * localedata/locales/ar_MA (abmon): Likewise. * localedata/locales/ar_TN (abmon): Likewise. * localedata/locales/ps_AF (abmon): Likewise. * localedata/locales/ug_CN (abmon): Likewise. * localedata/locales/ar_SA (abmon): Likewise, partially fixes bug 19066. * localedata/locales/ks_IN (abmon): A copy of mon. * localedata/locales/ur_IN (abmon): Oct reworded "اكتوبر" to "اکتوبر" (same change as mon). * localedata/locales/ur_PK (abmon): Same changes as mon applied. * localedata/locales/ps_AF (mon): May reworded "می" to "مۍ".

This patch fixes some build issues when including types/sigevent_t.h along with bits/pthreadtypes.h. Checked on x86_64-linux-gnu and on a build on supported major ABIs. [BZ #21715] * sysdeps/nptl/bits/pthreadtypes.h (__have_pthread_attr_t): Fix typo on definition.
2017-07-06x86-64: Align the stack in __tls_get_addr [BZ #21609]H.J. Lu
This change forces realignment of the stack pointer in __tls_get_addr, so that binaries compiled by GCCs older than GCC 4.9: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58066 continue to work even if vector instructions are used in glibc which require the ABI stack realignment. __tls_get_addr_slow is added to handle the slow paths in the default implementation of__tls_get_addr in elf/dl-tls.c. The new __tls_get_addr calls __tls_get_addr_slow after realigning the stack. Internal calls within ld.so go directly to the default implementation of __tls_get_addr because they do not need stack realignment. [BZ #21609] * sysdeps/x86_64/Makefile (sysdep-dl-routines): Add tls_get_addr. (gen-as-const-headers): Add rtld-offsets.sym. * sysdeps/x86_64/dl-tls.c: New file. * sysdeps/x86_64/rtld-offsets.sym: Likwise. * sysdeps/x86_64/tls_get_addr.S: Likewise. * sysdeps/x86_64/dl-tls.h: Add multiple inclusion guards. * sysdeps/x86_64/tlsdesc.sym (TI_MODULE_OFFSET): New.

2017-07-04Single threaded stdio optimizationSzabolcs Nagy
Locking overhead can be significant in some stdio operations that are common in single threaded applications. This patch adds the _IO_FLAGS2_NEED_LOCK flag to indicate if an _IO_FILE object needs to be locked and some of the stdio functions just jump to their _unlocked variant when not. The flag is set on all _IO_FILE objects when the first thread is created. A new GLIBC_PRIVATE libc symbol, _IO_enable_locks, was added to do this from libpthread. The optimization can be applied to more stdio functions, currently it is only applied to single flag check or single non-wide-char standard operations. The flag should probably be never set for files with _IO_USER_LOCK, but that's just a further optimization, not a correctness requirement. The optimization is valid in a single thread because stdio operations are non-as-safe (so lock state is not observable from a signal handler) and stdio locks are recursive (so lock state is not observable via deadlock). The optimization is not valid if a thread may be created while an stdio lock is taken and thus it should be disabled if any user code may run during an stdio operation (interposed malloc, printf hooks, etc). This makes the optimization more complicated for some stdio operations (e.g. printf), but those are bigger and thus less important to optimize so this patch does not try to do that. * libio/libio.h (_IO_FLAGS2_NEED_LOCK, _IO_need_lock): Define. * libio/libioP.h (_IO_enable_locks): Declare. * libio/Versions (_IO_enable_locks): New symbol. * libio/genops.c (_IO_enable_locks): Define.

2017-07-03resolv: Automatically reload a changed /etc/resolv.conf file [BZ #984]Florian Weimer
This commit enhances the stub resolver to reload the configuration in the per-thread _res object if the /etc/resolv.conf file has changed. The resolver checks whether the application has modified _res and will not overwrite the _res object in that case. The struct resolv_context mechanism is used to check the configuration file only once per name lookup.
