* linux: Only use 64-bit syscall if required for pselectAdhemerval Zanella2021-06-221-2/+1
| | | | | | | | | | | | | For !__ASSUME_TIME64_SYSCALLS there is no need to issue a 64-bit syscall if the provided timeout fits in a 32-bit one. The 64-bit usage should be rare since the timeout is a relative one. This also avoids the need to use supports_time64() (which breaks the usage case of live migration like CRIU or similar). Checked on i686-linux-gnu on a 4.15 kernel and on a 5.11 kernel (with and without --enable-kernel=5.1) and on x86_64-linux-gnu. Reviewed-by: Lukasz Majewski <lukma@denx.de>

* nptl: Export _pthread_cleanup_push, _pthread_cleanup_pop againFlorian Weimer2021-06-152-0/+4
| | | | | | | | | | These were turned into compat symbols as part of the libpthread move. It turns out they are used by language run-time libraries (e.g., the GCC D front end), so it makes to preserve them as external symbols even though they are not declared in any header file.

* y2038: Add support for 64-bit time on legacy ABIsAdhemerval Zanella2021-06-157-0/+148
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A new build flag, _TIME_BITS, enables the usage of the newer 64-bit time symbols for legacy ABI (where 32-bit time_t is default). The 64 bit time support is only enabled if LFS (_FILE_OFFSET_BITS=64) is also used. Different than LFS support, the y2038 symbols are added only for the required ABIs (armhf, csky, hppa, i386, m68k, microblaze, mips32, mips64-n32, nios2, powerpc32, sparc32, s390-32, and sh). The ABIs with 64-bit time support are unchanged, both for symbol and types redirection. On Linux the full 64-bit time support requires a minimum of kernel version v5.1. Otherwise, the 32-bit fallbacks are used and might results in error with overflow return code (EOVERFLOW). The i686-gnu does not yet support 64-bit time. This patch exports following rediretions to support 64-bit time: * libc: adjtime adjtimex clock_adjtime clock_getres clock_gettime clock_nanosleep clock_settime cnd_timedwait ctime ctime_r difftime fstat fstatat futimens futimes futimesat getitimer getrusage gettimeofday gmtime gmtime_r localtime localtime_r lstat_time lutimes mktime msgctl mtx_timedlock nanosleep nanosleep ntp_gettime ntp_gettimex ppoll pselec pselect pthread_clockjoin_np pthread_cond_clockwait pthread_cond_timedwait pthread_mutex_clocklock pthread_mutex_timedlock pthread_rwlock_clockrdlock pthread_rwlock_clockwrlock pthread_rwlock_timedrdlock pthread_rwlock_timedwrlock pthread_timedjoin_np recvmmsg sched_rr_get_interval select sem_clockwait semctl semtimedop sem_timedwait setitimer settimeofday shmctl sigtimedwait stat thrd_sleep time timegm timerfd_gettime timerfd_settime timespec_get utime utimensat utimes utimes wait3 wait4 * librt: aio_suspend mq_timedreceive mq_timedsend timer_gettime timer_settime * libanl: gai_suspend Reviewed-by: Lukasz Majewski <lukma@denx.de> Reviewed-by: Carlos O'Donell <carlos@redhat.com> Tested-by: Carlos O'Donell <carlos@redhat.com>

| | | | | | | | | | | | | | The symbol was moved using scripts/move-symbol-to-libc.py. There is a minor functionality enhancement: dlerror now sets errno if it was set as part of the exception. (This is the result of using %m in asprintf, to avoid the strerror PLT call.) The previous errno value upon function return was unpredictable. Documenting this as a feature is premature; we need to make sure that the error codes are meaningful when they are set by the dynamic loader.

| | | | | | | | | | | | | | | | | | | The symbols were moved using scripts/move-symbol-to-libc.py. The libpthread placeholder symbols need some changes because some symbol versions have gone away completely. But __errno_location@@GLIBC_2.0 still exists, so the GLIBC_2.0 version is still there. The internal __pthread_create symbol now points to the correct function, so the sysdeps/nptl/thrd_create.c override is no longer necessary. There was an issue how the hidden alias of pthread_getattr_default_np was defined, so this commit cleans up that aspects and removes the GLIBC_PRIVATE export altogether.

* Add C2X timespec_getresJoseph Myers2021-05-172-0/+2
| | | | | | | | | | | | | | | | | | | ISO C2X adds a timespec_getres function alongside the C11 timespec_get, with functionality similar to that of POSIX clock_getres (including allowing a NULL pointer to be passed to the function). Implement this function for glibc, similarly to the implementation of timespec_get. This includes a basic test like that of timespec_get, but no documentation in the manual, given that TIME_UTC and timespec_get aren't documented in the manual at all. The handling of 64-bit time follows that in timespec_get; people maintaining patch series for 64-bit time will need to update them accordingly (to export __timespec_getres64, redirect calls in time.h and run the test for _TIME_BITS=64). Tested for x86_64 and x86, and (previous version; only testcase differs) with build-many-glibcs.py.
