* htl: Move cleanup handling to non-private libc-lockSamuel Thibault2020-06-282-33/+70
| | | | | | | | | | | | | | | | | This adds sysdeps/htl/libc-lock.h which augments sysdeps/mach/libc-lock.h with the htl-aware cleanup handling. Otherwise inclusion of libc-lock.h without libc-lockP.h would keep only the mach-aware handling. This also fixes cleanup getting called when the binary is statically-linked without libpthread. * sysdeps/htl/libc-lockP.h (__libc_cleanup_region_start, __libc_cleanup_end, __libc_cleanup_region_end, __pthread_get_cleanup_stack): Move to... * sysdeps/htl/libc-lock.h: ... new file. (__libc_cleanup_region_start): Always set handler and arg. (__libc_cleanup_end): Always call the cleanup handler. (__libc_cleanup_push, __libc_cleanup_pop): New macros.
* htl: Fix includes for lockfileSamuel Thibault2020-06-283-6/+3
| | | | | | | | | | | These only need exactly to use __libc_ptf_call. * sysdeps/htl/flockfile.c: Include <libc-lockP.h> instead of <libc-lock.h> * sysdeps/htl/ftrylockfile.c: Include <libc-lockP.h> instead of <errno.h>, <pthread.h>, <stdio-lock.h> * sysdeps/htl/funlockfile.c: Include <libc-lockP.h> instead of <pthread.h> and <stdio-lock.h>
* htl: Add wrapper header for <semaphore.h> with hidden __sem_postFlorian Weimer2020-06-243-2/+11
| | | | | | | This is required to avoid a check-localplt failure due to a sem_post call through the PLT. Reviewed-by: Samuel Thibault <samuel.thibault@ens-lyon.org>
* htl: Fix case when sem_*wait is canceled while holding a tokenSamuel Thibault2020-06-241-2/+13
| | | | | | | | * sysdeps/htl/sem-timedwait.c (struct cancel_ctx): Add cancel_wake field. (cancel_hook): When unblocking thread, set cancel_wake field to 1. (__sem_timedwait_internal): Set cancel_wake field to 0 by default. On cancellation exit, check whether we hold a token, to be put back.
* htl: Make sem_*wait cancellations pointsSamuel Thibault2020-06-241-8/+84
| | | | | | | | | | | | | | By aligning its implementation on pthread_cond_wait. * sysdeps/htl/sem-timedwait.c (cancel_ctx): New structure. (cancel_hook): New function. (__sem_timedwait_internal): Check for cancellation and register cancellation hook that wakes the thread up, and check again for cancellation on exit. * nptl/tst-cancel13.c, nptl/tst-cancelx13.c: Move to... * sysdeps/pthread/: ... here. * nptl/Makefile: Move corresponding references and rules to... * sysdeps/pthread/Makefile: ... here.
* htl: Simplify non-cancel path of __pthread_cond_timedwait_internalSamuel Thibault2020-06-241-20/+21
| | | | | | | | | Since __pthread_exit does not return, we do not need to indent the noncancel path * sysdeps/htl/pt-cond-timedwait.c (__pthread_cond_timedwait_internal): Move cancelled path before non-cancelled path, to avoid "else" indentation.
* htl: Fix cleanup support for IO lockingSamuel Thibault2020-06-142-0/+90
| | | | | | | | | | * sysdeps/htl/stdio-lock.h: New file, registers locking cleanup to htl. * sysdeps/htl/libc-lockP.h: Include <libc-lock.h>. (__libc_cleanup_region_start, __libc_cleanup_end, __libc_cleanup_region_end): Override macros from <libc-lock.h> with versions which register cleanup to htl. (__pthread_get_cleanup_stack): Make reference weak for skipping registration on in the static non-libpthread case.
* htl: Add noreturn attribute on __pthread_exit forwardSamuel Thibault2020-06-141-2/+2

* hurd: Add __pthread_spin_wait and use itSamuel Thibault2020-02-1115-21/+21
| | | | | | | | | 900778283ac3 ("htl: make pthread_spin_lock really spin") made pthread_spin_lock really spin and not block, but the current users of __pthread_spin_lock were assuming that it blocks, i.e. they use it as a lightweight mutex fitting in just one int. __pthread_spin_wait provides that support back.

* htl: Do not put spin_lock inlines in public headersSamuel Thibault2020-02-092-36/+36
| | | | | | They were not getting used anyway. Also do not make libsupport use them, it would make tests using it have to be made to link against libmachuser for gsync_wait.

* htl: Add __errno_location and __h_errno_locationSamuel Thibault2020-01-041-0/+4
| | | | | | | | As explained on https://sourceware.org/ml/libc-alpha/2020-01/msg00049.html the presence of __errno_location in libpthread.so on GNU/Linux makes libpthread getting linked in for libstdc++. This aligns on that behavior, to avoid issues that only GNU/Hurd would get.
* htl: Move pthread_atfork to libc_nonshared.aSamuel Thibault2020-01-042-3/+3
| | | | | | | | | | | | | | | This follows bd60ce86520b ('nptl: Move pthread_atfork to libc_nonshared.a') with the same rationale: there is no non-libpthread equivalent to be used for making linking against libpthread optional. libpthread_nonshared.a is unused after this, so remove it from the build. There is no ABI impact because pthread_atfork was implemented using __register_atfork in libc even before this change. pthread_atfork has to be a weak alias because pthread_* names are not reserved in libc.

* time: Introduce function to check correctness of nanoseconds valueLukasz Majewski2019-10-275-5/+10
| | | | | | | | | | | | | | | The valid_nanoseconds () static inline function has been introduced to check if nanoseconds value is in the correct range - greater or equal to zero and less than 1000000000. The explicit #include <time.h> has been added to files where it was missing. The __syscall_slong_t type for ns has been used to avoid issues on x32. Tested with: - scripts/build-many-glibcs.py - make PARALLELMFLAGS="-j12" && make PARALLELMFLAGS="-j12" xcheck on x86_64
