* aarch64: Disable using DC ZVA in emag memsetFeng Xue2019-08-141-0/+7

* Declare some TS 18661-4 interfaces for C2X.Joseph Myers2019-08-131-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | C2X (current version in git, postdating the most recent public draft available as a PDF on the WG14 website) adds the interfaces from TS 18661-4, other than the reduction functions, as unconditionally required and visible in <math.h> for hosted implementations; the __STDC_WANT_IEC_60559_FUNCS_EXT__ macro is not included in C2X at all (as the reduction functions aren't included at all, expected to end up in a version of the TS updated to be relative to C2X). This patch updates the glibc headers accordingly, following the same pattern used for 18661-1 functions. As the only 18661-4 functions currently supported are the exp10 functions that have been in glibc for a very long time, this means that in fact __GLIBC_USE (IEC_60559_FUNCS_EXT) ends up being used only to determine the definition of __GLIBC_USE_IEC_60559_FUNCS_EXT_C2X, not yet in any headers other than bits/libc-header-start.h. (I hope to add the other 18661-4 functions to glibc at some point; the main complication is the current lack of MPFR support for many of these functions.) Tested for x86_64. * bits/libc-header-start.h (__GLIBC_USE_IEC_60559_FUNCS_EXT): Update comment. (__GLIBC_USE_IEC_60559_FUNCS_EXT_C2X): New macro. * bits/math-finite.h [__GLIBC_USE (IEC_60559_FUNCS_EXT)]: Change to [__GLIBC_USE (IEC_60559_FUNCS_EXT_C2X)]. * math/bits/mathcalls.h [__GLIBC_USE (IEC_60559_FUNCS_EXT)]: Likewise.

* Declare most TS 18661-1 interfaces for C2X.Joseph Myers2019-08-131-0/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | C2X adds the interfaces from TS 18661-1, and all except a handful in Annex F are unconditionally visible in C2X rather than only visible when __STDC_WANT_IEC_60559_BFP_EXT__ is defined. This patch updates glibc headers accordingly: most uses of __GLIBC_USE (IEC_60559_BFP_EXT) are changed to a new __GLIBC_USE (IEC_60559_BFP_EXT_C2X). (Regarding totalorder and totalordermag, the type-generic macros in tgmath.h will go away when the functions are changed to take pointer arguments.) * bits/libc-header-start.h (__GLIBC_USE_IEC_60559_BFP_EXT): Update comment.

* Declare memccpy, strdup, strndup for C2X.Joseph Myers2019-08-131-0/+4
| | | | | | | | | | | | C2X adds the memccpy, strdup and strndup functions. This patch duly adds __GLIBC_USE (ISOC2X) to the conditions under which <string.h> declares them. Tested for x86_64. * string/string.h (memccpy): Also declare if [__GLIBC_USE (ISOC2X)]. (strdup): Likewise. (strndup): Likewise.
* Add feature test macro _ISOC2X_SOURCE.Joseph Myers2019-08-131-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch starts preparation for C2X support in glibc headers by adding a feature test macro _ISOC2X_SOURCE and corresponding __GLIBC_USE (ISOC2X). (I chose to use the newer __GLIBC_USE style for this rather than the older __USE_* macros tested with #ifdef.) As with other such macros, C2X features are also enabled by compiling for a standard newer than C17, or by using _GNU_SOURCE. This patch does not itself enable anything new in the headers for C2X; that is to be done in followup patches. (For example, most of the TS 18661-1 functions should be declared for C2X without any __STDC_WANT_IEC_60559_BFP_EXT__ being needed, but the ones that 18661-1 adds to Annex F because of their close relation to IEEE 754 formats do still need the WANT macro in C2X.) Once C2X becomes an actual standard we'll presumably move to using the actual year in the feature test macro and __GLIBC_USE, with some period when both macro spellings are accepted, as was done with _ISOC9X_SOURCE. Tested for x86_64. * include/features.h (_ISOC2X_SOURCE): New feature test macro. Undefine and define to 1 if [_GNU_SOURCE]. (__GLIBC_USE_ISOC2X): New macro. Undefine and redefine depending on [_ISOC2X_SOURCE] and [__STDC_VERSION__ > 201710L]. (__USE_ISOC11): Also define to 1 if [_ISOC2X_SOURCE]. (__USE_ISOC99): Likewise. (__USE_ISOC95): Likewise. * manual/creature.texi (_ISOC2X_SOURCE): Document.
* login: Assume that _HAVE_UT_* constants are trueFlorian Weimer2019-08-131-0/+26

* elf: Support elf/tst-dlopen-aout in more configurationsFlorian Weimer2019-08-121-0/+9
| | | | | | | | | | | | dlopen can no longer open PIE binaries, so it is not necessary to link the executable as non-PIE to trigger a dlopen failure. If we hard-code the path to the real executable, we can run the test with and without hard-coded paths because the dlopen path will not be recognized as the main program in both cases. (With an explict loader invocation, the loader currently adds argv[0] to l_libname for the main map and the dlopen call suceeds as a result; it does not do that in standard mode.)

* malloc: Fix missing accounting of top chunk in malloc_info [BZ #24026]Niklas Hambüchen2019-08-081-0/+6
| | | | | | | | | | | | Fixes `<total type="rest" size="..."> incorrectly showing as 0 most of the time. The rest value being wrong is significant because to compute the actual amount of memory handed out via malloc, the user must subtract it from <system type="current" size="...">.

* Add SYNC_FILE_RANGE_WRITE_AND_WAIT from Linux 5.2 to bits/fcntl-linux.h.Joseph Myers2019-08-071-0/+5

* iconv: Revert steps array reference counting changesFlorian Weimer2019-07-311-0/+20
| | | | | | | | | | | | | | | The changes introduce a memory leak for gconv steps arrays whose first element is an internal conversion, which has a fixed reference count which is not decremented. As a result, after the change in commit 50ce3eae5ba304650459d4441d7d246a7cefc26f, the steps array is never freed, resulting in an unbounded memory leak. This reverts commit 50ce3eae5ba304650459d4441d7d246a7cefc26f ("gconv: Check reference count in __gconv_release_cache [BZ #24677]") and commit 7e740ab2e7be7d83b75513aa406e0b10875f7f9c ("libio: Fix gconv-related memory leak [BZ #24583]").

| | | | | | | | | | | | | | | | | | | | The kernel changes for a 64-bit time_t on 32-bit architectures resulted in <asm/socket.h> indirectly including <linux/posix_types.h>. The latter is not namespace-clean for the POSIX version of <sys/socket.h>. This issue has persisted across several Linux releases, so this commit creates our own copy of the SO_* definitions for !__USE_MISC mode. The new test socket/tst-socket-consts ensures that the copy is consistent with the kernel definitions (which vary across architectures). The test is tricky to get right because CPPFLAGS includes include/libc-symbols.h, which in turn defines _GNU_SOURCE unconditionally. Tested with build-many-glibcs.py. I verified that a discrepancy in the definitions actually results in a failure of the socket/tst-socket-consts test.
* test-container: Install with $(all-subdirs) [BZ #24794]Tulio Magno Quites Machado Filho2019-07-231-0/+4
| | | | | | | | | | | | | Whenever a sub-make is created, it inherits the variable subdirs from its parent. This is also true when make check is called with a restricted list of subdirs. In this scenario, make install is executed "partially" and testroot.pristine ends up with an incomplete installation. [BZ #24794] * Makefile (testroot.pristine/install.stamp): Pass subdirs='$(all-subdirs)' to make install. Reviewed-by: DJ Delorie <dj@redhat.com>
* test-container: Avoid copying unintended system librariesTulio Magno Quites Machado Filho2019-07-231-0/+5
| | | | | | | | | | | | | | Some DSOs are distributed in hardware capability directories, e.g. /usr/lib64/power7/libc.so.6 Whenever the processor is able to use one of these hardware-enabled DSOs, testroot.pristine ends up with copies of glibc-provided libraries from the system because it can't overwrite or remove them. This patch avoids the unintended copies by executing ld.so with the same arguments passed to each glibc test. * Makefile (testroot.pristine/install.stamp): Execute ld.so with the same arguments used in all tests.

* nptl: Add POSIX-proposed _clock functions to hppa pthread.hAdhemerval Zanella2019-07-181-0/+5
| | | | | | | | | | | | | | The pthread _clock functions that were recently added to nptl need to be declared in hppa's pthread.h too. After this change, the function declaration part of sysdeps/nptl/pthread.h and sysdeps/unix/sysv/linux/hppa/pthread.h are identical. * sysdeps/unix/sysv/linux/hppa/pthread.h: Add declarations of functions recently added to sysdeps/nptl/pthread.h: pthread_mutex_clocklock, pthread_rwlock_clockrdlock, pthread_rwlock_clockwrlock and pthread_cond_clockwait.

* nptl: Remove unnecessary forwarding of pthread_cond_clockwait from libcMike Crowe2019-07-181-0/+10
| | | | | | | | | | | | | | | | | | | | In afe4de7d283ebd88157126c5494ce1796194c16e, I added forwarding functions from libc to libpthread for __pthread_cond_clockwait and pthread_cond_clockwait to mirror those for pthread_cond_timedwait. These are unnecessary[1], since these functions aren't (yet) being called from within libc itself. Let's remove them. * nptl/forward.c: Remove unnecessary __pthread_cond_clockwait and pthread_cond_clockwait forwarding functions. There are no internal users, so it is unnecessary to expose these functions in libc.so. * sysdeps/nptl/pthread-functions.h (pthread_functions): Remove unnecessary ptr___pthread_cond_clockwait member. * nptl/nptl-init.c (pthread_functions): Remove assignment of removed member.

* Afar locales: Months and days updated from CLDR (bug 21897).Rafal Luzynski2019-07-171-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit updates month and weekday names (full and abbreviated) from CLDR 35.1 with the following exceptions. It was not clear why the full name of February in aa_DJ and aa_ER was "Kudo" while the abbreviated version is "Nah" but some additional sources [1] [2] as well as the content of aa_ER and aa_ER@saaho suggest it should be "Naharsi Kudo". This commit consequently sets the translation of February to "Naharsi Kudo" in aa_DJ and aa_ET. aa_ER@saaho is not supported by CLDR but since the month names were identical to aa_ER before this commit, the same values have been copied from aa_ER.
