stime() has been withdrawn from glibc (12cbde1dae6f "Use clock_settime to implement stime; withdraw stime.")
Implement the target stime() syscall using host clock_settime(CLOCK_REALTIME, ...) as it is done internally in glibc. Tested qemu-ppc/x86_64 with: #include <time.h> #include <stdio.h> int main(void) { time_t t; int ret; /* date -u -d"2019-11-12T15:11:00" "+%s" */ t = 1573571460; ret = stime(&t); printf("ret %d\n", ret); return 0; } # date; ./stime; date Tue Nov 12 14:18:32 UTC 2019 ret 0 Tue Nov 12 15:11:00 UTC 2019 Buglink: https://bugs.launchpad.net/qemu/+bug/1852115 Reported-by: Cole Robinson <crobi...@redhat.com> Signed-off-by: Laurent Vivier <laur...@vivier.eu> Reviewed-by: Peter Maydell <peter.mayd...@linaro.org> Message-Id: <20191112142556.6335-1-laur...@vivier.eu> --- linux-user/syscall.c | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) diff --git a/linux-user/syscall.c b/linux-user/syscall.c index 4e97bcf1e5a9..ce399a55f0db 100644 --- a/linux-user/syscall.c +++ b/linux-user/syscall.c @@ -7764,10 +7764,12 @@ static abi_long do_syscall1(void *cpu_env, int num, abi_long arg1, #ifdef TARGET_NR_stime /* not on alpha */ case TARGET_NR_stime: { - time_t host_time; - if (get_user_sal(host_time, arg1)) + struct timespec ts; + ts.tv_nsec = 0; + if (get_user_sal(ts.tv_sec, arg1)) { return -TARGET_EFAULT; - return get_errno(stime(&host_time)); + } + return get_errno(clock_settime(CLOCK_REALTIME, &ts)); } #endif #ifdef TARGET_NR_alarm /* not on alpha */ -- 2.21.0
