y2038: nptl: Convert sem_{clock|timed}wait to support 64 bit time
The sem_clockwait and sem_timedwait have been converted to support 64 bit time.
This change reuses futex_abstimed_wait_cancelable64 function introduced earlier.
The sem_{clock|timed}wait only accepts absolute time. Moreover, there is no
need to check for NULL passed as *abstime pointer to the syscalls as both calls
have exported symbols marked with __nonull attribute for abstime.
For systems with __TIMESIZE != 64 && __WORDSIZE == 32:
- Conversion from 32 bit time to 64 bit struct __timespec64 was necessary
- Redirection to __sem_{clock|timed}wait64 will provide support for 64 bit
time
Build tests:
./src/scripts/build-many-glibcs.py glibcs
Run-time tests:
- Run specific tests on ARM/x86 32bit systems (qemu):
https://github.com/lmajewski/meta-y2038 and run tests:
https://github.com/lmajewski/y2038-tests/commits/master
Above tests were performed with Y2038 redirection applied as well as without
to test the proper usage of both __sem_{clock|timed}wait64 and
__sem_{clock|timed}wait.
