* linux: Require /dev/shm as the shared memory file systemFlorian Weimer2021-02-081-31/+0
| | | | | | | | | | | | | | | | | | | | | Previously, glibc would pick an arbitrary tmpfs file system from /proc/mounts if /dev/shm was not available. This could lead to an unsuitable file system being picked for the backing storage for shm_open, sem_open, and related functions. This patch introduces a new function, __shm_get_name, which builds the file name under the appropriate (now hard-coded) directory. It is called from the various shm_* and sem_* function. Unlike the SHM_GET_NAME macro it replaces, the callers handle the return values and errno updates. shm-directory.c is moved directly into the posix subdirectory because it can be implemented directly using POSIX functionality. It resides in libc because it is needed by both librt and nptl/htl. In the sem_open implementation, tmpfname is initialized directly from a string constant. This happens to remove one alloca call. Checked on x86_64-linux-gnu.

* nptl: Fix __futex_clocklock64 return error check [BZ #26964]Lucas A. M. Magalhaes2020-12-011-4/+3
| | | | | | | | | | | | | | | | | The earlier implementation of this, __lll_clocklock, calls lll_clockwait that doesn't return the futex syscall error codes. It always tries again if that fails. However in the current implementation, when the futex returns EAGAIN, __futex_clocklock64 will also return EGAIN, even if the futex is taken. This patch fixes the EAGAIN issue and also adds a check for EINTR. As futex syscall can return EINTR if the thread is interrupted by a signal. In this case I'm assuming the function should continue trying to lock as there is no mention to about it on POSIX. Also add a test for both scenarios.

* Avoid -Wstringop-overflow warning in pthread_cleanup_push macrosJoseph Myers2020-10-301-10/+27
| | | | | | | | | | | | | | | | | | | | | GCC 11 introduces a -Wstringop-overflow warning for calls to functions with an array argument passed as a pointer to memory not large enough for that array. This includes the __sigsetjmp calls from pthread_cleanup_push macros, because those use a structure in __pthread_unwind_buf_t, which has a common initial subsequence with jmp_buf but does not include the saved signal mask; this is OK in this case because the second argument to __sigsetjmp is 0 so the signal mask is not accessed. To avoid this warning, use a function alias __sigsetjmp_cancel with first argument an array of exactly the type used in the calls to the function, if using GCC 11 or later. With older compilers, continue to use __sigsetjmp with a cast, to avoid any issues with compilers predating the returns_twice attribute not applying the same special handling to __sigsetjmp_cancel as to __sigsetjmp. Tested with build-many-glibcs.py for arm-linux-gnueabi that this fixes the testsuite build failures.
* y2038: nptl: Provide __futex_clock_wait_bitset64 to support 64 bit bitsetLukasz Majewski2020-10-212-1/+52
| | | | | | | | | | | | | | | The commit: "y2038: nptl: Convert pthread_mutex_{clock|timed}lock to support 64 bit" SHA1: 29e9874a048f47e2d46c40253036c8d2de921548 introduced support for 64 bit timeouts. Unfortunately, it was missing the code for bitset - i.e. lll_futex_clock_wait_bitset C preprocessor macro was used. As a result the 64 bit struct __timespec64 was coerced to 32 bit struct timespec and regression visible as timeout was observed (nptl/tst-robust10 on s390).

This change uses: - New __futex_clocklock_wait64 (instead of lll_timedwait) from ./sysdeps/nptl/futex-helpers.c and - New __futex_clocklock64 function (instead of lll_clocklock) - New futex_lock_pi64 defined in sysdeps/nptl/futex-internal.h The pthread_mutex_{clock|timed}lock only accepts absolute time. Moreover, there is no need to check for NULL passed as *abstime pointer to the syscalls as those calls have exported symbols marked with __nonull attribute for abstime. Some architectures - namely x86, powerpc and s390 - do support lock elision. For those - adjustments have been made in arch specific elision-*.c files to use __futex_clocklock64 instead of lll_clocklock. The __lll_lock_elision (aliased to __lll_clocklock_elision in e.g. sysdeps/unix/sysv/linux/s390/elision-timed.c) just uses, in this patch provided, __futex_clocklock64.

* Fix GCC 11 -Warray-parameter warning for __sigsetjmp (bug 26647)Joseph Myers2020-10-051-2/+3
| | | | | | | | | | | | | | | | | | | | | | | This patch fixes part of bug 26647 (-Werror=array-parameter error building with GCC 11 because of __sigsetjmp being declared using an array parameter in one header and a pointer parameter in another). The fix is to split the struct __jmp_buf_tag definition out to a separate bits/types/ header so it can be included in pthread.h, so that pthread.h can declare __sigsetjmp with the type contents visible, so can use an array (as in setjmp.h) rather than a pointer in the declaration. Note that several other build failures with GCC 11 remain. This does not fix the jmp_buf-related -Wstringop-overflow errors (also discussed in bug 26647), or -Warray-parameter errors for other functions (bug 26686), or -Warray-bounds errors (bug 26687). Tested, with older compilers, natively for x86_64 and with build-many-glibc.py for aarch64-linux-gnu. Tested with build-many-glibcs.py with GCC mainline for aarch64-linux-gnu that this gets past the -Warray-parameter issue for __sigsetjmp (with the next build failure being the other one discussed in bug 26647).

This patch removes the 'err' argument on INTERNAL_SYSCALL* macro and remove the INTERNAL_SYSCALL_DECL usage. Checked with a build against all affected ABIs.
