| | | | | When it is not hardcoded by the architecture with PAGESIZE, we need to use the dynamic values from __vm_page_size.

| | | | So they can be checked with htl too.
* htl: make pthread_spin_lock really spinSamuel Thibault2020-02-091-1/+1
| | | | | __spin_lock would actually use gsync_wait to block, which is not what pthread_spin_lock is about.

* 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.
* pthread: Move basic tests from nptl to sysdeps/pthreadSamuel Thibault2020-02-099-3/+8
| | | | So they can be checked with htl too.
* htl: Fix calling pthread_exit in the child of a forkSamuel Thibault2020-02-091-0/+9
| | | | | We need to reset the threads counter, otherwise pthread_exit() would not call exit(0).

| | | | | | Particularly on CPUs without ERMS, the string instructions are slow, so it is unclear whether this architecture-specific implementation is in fact an optimization.

* y2038: linux: Provide __settimeofday64 implementationLukasz Majewski2020-02-072-0/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch provides new __settimeofday64 explicit 64 bit function for setting 64 bit time in the kernel (by internally calling __clock_settime64). Moreover, a 32 bit version - __settimeofday has been refactored to internally use __settimeofday64. The __settimeofday is now supposed to be used on systems still supporting 32 bit time (__TIMESIZE != 64) - hence the necessary conversion of struct timeval to 64 bit struct __timespec64. Internally the settimeofday uses __settimeofday64. This patch is necessary for having architectures with __WORDSIZE == 32 Y2038 safe.

| | | | | | | | | | | | | | | | The name 'valid_timeval64_to_timeval' suggest conversion of struct __timeval64 to struct timeval (as in ./include/time.h). As on the alpha the struct timeval supports 64 bit time, it seems more feasible to emphasis struct timeval32 in the conversion function name.

| | | | | | | | | | | | | | | | | | Without this patch the naming convention for functions to convert struct timeval32 to struct timeval (which supports 64 bit time on Alpha) was a bit misleading. The name 'valid_timeval_to_timeval64' suggest conversion of struct timeval to struct __timeval64 (as in ./include/time.h). As on alpha the struct timeval supports 64 bit time it seems more readable to emphasis struct timeval32 in the conversion function name.

| | | | | | | | | | | | | | This type is a glibc's "internal" type similar to struct timeval but whose tv_sec field is a __time64_t rather than a time_t, which makes it Y2038-proof. This struct is NOT supposed to be passed to the kernel - instead it shall be converted to struct __timespec64 and clock_[sg]ettime syscalls shall be used (which are now Y2038 safe).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch provides new instance of Linux specific timespec_get.c file placed in ./sysdeps/unix/sysv/linux/. When compared to this file version from ./time directory, it provides __timespec_get64 explicit 64 bit function for getting 64 bit time in the struct __timespec64 (for compilation using C11 standard). Moreover, a 32 bit version - __timespec_get internally uses __timespec_get64. The __timespec_get is now supposed to be used on systems still supporting 32 bit time (__TIMESIZE != 64) - hence the necessary conversion to 32 bit struct timespec. Internally the timespec_get uses __clock_gettime64. This patch is necessary for having architectures with __WORDSIZE == 32 Y2038 safe.

| | | | | | | | | | | | | | See https://bugzilla.redhat.com/show_bug.cgi?id=1653942 This test depends on the kernel's assignment of memory regions, but running under ld.so explicitly changes those assignments, sometimes sufficiently to cause the test to fail (esp with address space randomization). The easiest way to "fix" the test, is to run it the way the user would - without ld.so. Running it in a container does that. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
