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".

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.

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.
2017-07-03resolv: Mirror the entire resolver configuration in struct resolv_confFlorian Weimer
This commit adds the remaining unchanging members (which are loaded from /etc/resolv.conf) to struct resolv_conf. The extended name server list is currently not used by the stub resolver. The switch depends on a cleanup: The _u._ext.nssocks array stores just a single socket, and needs to be replaced with a single socket value. (The compatibility gethostname implementation does not use the extended addres sort list, either. Updating the compat code is not worthwhile.)
2017-07-03resolv: Lift domain search list limits [BZ #19569] [BZ #21475]Florian Weimer
This change uses the extended resolver state in struct resolv_conf to store the search list. If applications have not patched the _res object directly, this extended search list will be used by the stub resolver during name resolution.
2017-07-03resolv: Introduce struct resolv_conf with extended resolver stateFlorian Weimer
This change provides additional resolver configuration state which is not exposed through the _res ABI. It reuses the existing initstamp field in the supposedly-private part of _res. Some effort is undertaken to avoid memory safety issues introduced by applications which directly patch the _res object. With this commit, only the initstamp field is moved into struct resolv_conf. Additional members will be added later, eventually migrating the entire resolver configuration.
2017-07-03resolv: Introduce struct resolv_context [BZ #21668]Florian Weimer
struct resolv_context objects provide a temporary resolver context which does not change during a name lookup operation. Only when the outmost context is created, the stub resolver configuration is verified to be current (at present, only against previous res_init calls). Subsequent attempts to obtain the context will reuse the result of the initial verification operation. struct resolv_context can also be extended in the future to store data which needs to be deallocated during thread cancellation.

2017-06-30float128: Add signbit alternative for old compilersGabriel F. T. Gomes
In math/math.h, __MATH_TG will expand signbit to __builtin_signbit*, e.g.: __builtin_signbitf128, before GCC 6. However, there has never been a __builtin_signbitf128 in GCC and the type-generic builtin is only available since GCC 6. For older GCC, this patch defines __builtin_signbitf128 to __signbitf128, so that the internal function is used instead of the non-existent builtin. This patch also changes the implementation of __signbitf128, because it was reusing the implementation of __signbitl from ldbl-128, which calls __builtin_signbitl. Using the long double version of the builtin is not correct on machines where _Float128 is ABI-distinct from long double (i.e.: ia64, powerpc64le, x86, x86_84). The new implementation does not rely on builtins when being built with GCC versions older than 6.0. The new code does not currently affect powerpc64le builds, because only GCC 6.2 fulfills the requirements from configure. It might affect powerpc64le builds if those requirements are backported to older versions of the compiler. The new code affects x86_64 builds, since glibc is supposed to build correctly with older versions of GCC. Tested for powerpc64le and x86_64. * include/math.h (__signbitf128): Define as hidden. * sysdeps/ieee754/float128/s_signbitf128.c (__signbitf128): Reimplement without builtins. * sysdeps/ia64/bits/floatn.h [!__GNUC_PREREQ (6, 0)] (__builtin_signbitf128): Define to __signbitf128. * sysdeps/powerpc/bits/floatn.h: Likewise. * sysdeps/x86/bits/floatn.h: Likewise.
