* y2038: linux: Provide __utime64 implementationLukasz Majewski2020-03-031-0/+56
This patch replaces auto generated wrapper (as described in sysdeps/unix/sysv/linux/syscalls.list) for utime with one which adds extra support for setting file's access and modification 64 bit time on machines with __TIMESIZE != 64. Internally, the __utimensat_time64 helper function is used. This patch is necessary for having architectures with __WORDSIZE == 32 && __TIMESIZE != 64 Y2038 safe. Moreover, a 32 bit version - __utime has been refactored to internally use __utime64. The __utime is now supposed to be used on systems still supporting 32 bit time (__TIMESIZE != 64) - hence the necessary conversion between struct utimbuf and struct __utimbuf64. 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 proper usage of both __utime64 and __utime.
