* nptl: Move pthread_sigqueue into libcFlorian Weimer2021-05-1761-29/+83

* nptl: Move pthread_getcpuclockid into libcFlorian Weimer2021-05-1761-29/+70
| | | | | | | | | | | | | The symbol was moved using scripts/move-symbol-to-libc.py. __libpthread_version_placeholder@@GLIBC_2.2 is needed by this change; the Versions entry for GLIBC_2.2 in libpthread had leftover symbols due to an error in a previous conflict resolution. The condition for the placeholder symbol is complicated because some architectures have earlier symbols at the GLIBC_2.2 symbol versions, so the placeholder is not required there (yet).

| | | | | | | | | | | The symbol was moved using scripts/move-symbol-to-libc.py. A new placeholder symbol __libpthread_version_placeholder@GLIBC_2.18 is needed to keep the GLIBC_2.18 symbol version in libpthread. The __pthread_getattr_default_np@@GLIBC_PRIVATE export is used from pthread_create. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

* Linux: Simplify and fix the definition of SINGLE_THREAD_PFlorian Weimer2021-05-101-29/+7
| | | | | | | | | | | | | | Always use __libc_multiple_threads if beneficial, and do not assume the the dynamic loader is single-threaded. This assumption could become incorrect by accident once more code is moved from libpthread into it. The previous commit introducing the NO_SYSCALL_CANCEL_CHECKING macro enables this change. Do not hint to the compiler that multi-threaded programs are unlikely (which is not quite true anymore).

* Linux: Explicitly disable cancellation checking in the dynamic loaderFlorian Weimer2021-05-101-2/+9
| | | | | | | | | | | | | Historically, SINGLE_THREAD_P is defined to 1 in the dynamic loader. This has the side effect of disabling cancellation points. In order to enable future use of SINGLE_THREAD_P for single-thread optimizations in the dynamic loader (which becomes important once more code is moved from libpthread), introduce a new NO_SYSCALL_CANCEL_CHECKING macro which is always 1 for IS_IN (rtld), indepdently of the actual SINGLE_THREAD_P value.

* linux: implement ttyname as a wrapper around ttyname_r.Érico Nogueira2021-05-072-159/+13
| | | | | | | | | | | | | Big win in binary size and avoids duplicating the logic in multiple places. On x86_64, dropped from 1883206 to 1881790, a 1416 byte decrease. Also changed logic to track if ttyname_buf has been allocated by checking if it's NULL instead of tracking buflen as an additional variable.

* Annotate additional APIs with GCC attribute access.Martin Sebor2021-05-062-1/+13
| | | | | | | | | | | | | | | | This change continues the improvements to compile-time out of bounds checking by decorating more APIs with either attribute access, or by explicitly providing the array bound in APIs such as tmpnam() that expect arrays of some minimum size as arguments. (The latter feature is new in GCC 11.) The only effects of the attribute and/or the array bound is to check and diagnose calls to the functions that fail to provide a sufficient number of elements, and the definitions of the functions that access elements outside the specified bounds. (There is no interplay with _FORTIFY_SOURCE here yet.) Tested with GCC 7 through 11 on x86_64-linux.
