For time, the iFUNC already uses expected name so it affects only the static build. The clock_getres is a new implementation added on Linux 5.3 (f66501dc53e72). Checked on x86-linux-gnu and i686-linux-gnu. --- sysdeps/unix/sysv/linux/i386/sysdep.h | 2 ++ sysdeps/unix/sysv/linux/x86_64/sysdep.h | 2 ++ 2 files changed, 4 insertions(+) diff --git a/sysdeps/unix/sysv/linux/i386/sysdep.h b/sysdeps/unix/sysv/linux/i386/sysdep.h index 7066ddc214..b2e750d490 100644 --- a/sysdeps/unix/sysv/linux/i386/sysdep.h +++ b/sysdeps/unix/sysv/linux/i386/sysdep.h @@ -315,6 +315,8 @@ struct libc_do_syscall_args /* List of system calls which are supported as vsyscalls. */ # define HAVE_CLOCK_GETTIME_VSYSCALL "__vdso_clock_gettime" # define HAVE_GETTIMEOFDAY_VSYSCALL "__vdso_gettimeofday" +# define HAVE_TIME_VSYSCALL "__vdso_time" +# define HAVE_CLOCK_GETRES_VSYSCALL "__vdso_clock_getres" /* Define a macro which expands inline into the wrapper code for a system call.
