* 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.

| | | | | | | | | | | | The symbol was moved using scripts/move-symbol-to-libc.py. A small adjust to the sem_unlink implementation is necessary to avoid a check-localplt failure.

| | | | | | | | | | | The symbols were moved using move-symbol-to-libc.py. Both functions are moved at the same time because they depend on internal functions in sysdeps/pthread/sem_routines.c, which are moved in this commit as well.

* nptl: Consolidate async cancel enable/disable implementation in libcFlorian Weimer2021-05-052-42/+7
| | | | | | | | | | | | | | Previously, the source file nptl/cancellation.c was compiled multiple times, for libc, libpthread, librt. This commit switches to a single implementation, with new __pthread_enable_asynccancel@@GLIBC_PRIVATE, __pthread_disable_asynccancel@@GLIBC_PRIVATE exports. The almost-unused CANCEL_ASYNC and CANCEL_RESET macros are replaced by LIBC_CANCEL_ASYNC and LIBC_CANCEL_ASYNC macros. They call the __pthread_* functions unconditionally now. The macros are still needed because shared code uses them; Hurd has different definitions. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

* linux: use __fd_to_filename helper function instead of snprintf.Érico Nogueira2021-05-032-16/+7

* linux: Add execveat system call wrapperAlexandra Hájková2021-05-0333-0/+64
| | | | | | | | | | | It operates similar to execve and it is is already used to implement fexecve without requiring /proc to be mounted. However, different than fexecve, if the syscall is not supported by the kernel an error is returned instead of trying a fallback. Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.
