* nptl: Remove unnecessary forwarding of pthread_cond_clockwait from libcMike Crowe2019-07-181-5/+0
| | | | | | | | | | | | | | | | | | | | 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.

* nptl: Add POSIX-proposed pthread_cond_clockwaitMike Crowe2019-07-121-0/+5

Currently supports CLOCK_REALTIME and CLOCK_MONOTONIC and returns EINVAL if any other clock is specified. Includes feedback from many others. This function was originally proposed[1] as pthread_cond_timedwaitonclock_np, but The Austin Group preferred the new name. * nptl/Makefile: Add tst-cond26 and tst-cond27 * nptl/Versions (GLIBC_2.30): Add pthread_cond_clockwait * sysdeps/nptl/pthread.h: Likewise * nptl/forward.c: Add __pthread_cond_clockwait * nptl/forward.c: Likewise * nptl/pthreadP.h: Likewise * sysdeps/nptl/pthread-functions.h: Likewise * nptl/pthread_cond_wait.c (__pthread_cond_wait_common): Add clockid parameter and comment describing why we don't need to check its value.

* nptl: Implement pthread_self in libc.so [BZ #22635]Florian Weimer2017-12-201-4/+0
| | | | | | | | | | | | | | | | | All binaries use TLS and thus need a properly set up TCB, so we can simply return its address directly, instead of forwarding to the libpthread implementation from libc. For versioned symbols, the dynamic linker checks that the soname matches the name supplied by the link editor, so a compatibility symbol in libpthread is needed. To avoid linking against the libpthread function in all cases, we would have to bump the symbol version of libpthread in libc.so and supply a compat symbol. This commit does not do that because the function implementation is so small, so the overhead by two active copies of the same function might well be smaller than the increase in symbol table size.
