Are you sure you are testing it properly? As indicated by Andreas, it
seems a mismatch between ld.so and libc.so. I just setup a debian 9
VM with both a 4.9 and 5.4 kernel and a simple test:
--
#include <time.h>
int main ()
{
clock_gettime (CLOCK_REALTIME, &(struct timespec) {});
clock_gettime (CLOCK_MONOTONIC, &(struct timespec) {});
clock_gettime (CLOCK_BOOTTIME, &(struct timespec) {});
return 0;
}
--
does show the expected results. On 4.9 kernel I am seeing:
15:36:06 syscall_0x193(0, 0xbed9a3d8, 0xc8, 0, 0xbed9a3d8, 0) = -1 ENOSYS (Function not implemented)
15:36:06 clock_gettime(CLOCK_BOOTTIME, {tv_sec=1303, tv_nsec=570795799}) = 0
15:36:06 exit_group(0) = ?
15:36:06 +++ exited with 0 +++
While on a 5.4 kernel:
syscall_0x193(0, 0xbedfb3e8, 0xc8, 0, 0xbedfb3e8, 0) = 0
syscall_0x193(0x1, 0xbedfb3e8, 0xc8, 0, 0xbedfb3e8, 0x1) = 0
syscall_0x193(0x7, 0xbedfb3e8, 0xc8, 0, 0xbedfb3e8, 0x7) = 0
(arm clock_gettime64 vDSO was added on 5.5).
