This is because + the Linux kernel reused the API, on some architectures, to describe + a system-wide time-zone-like offset between the software clock + maintained by the kernel, and the "RTC" clock that keeps time when + the system is shut down. + + However, to reduce the odds of this offset being set by accident, + settimeofday can no longer be used to set the time and the offset + simultaneously. If both of its two arguments are non-null, the call + will fail (setting errno to EINVAL). + + Callers attempting to set this offset should also be prepared for + the call to fail and set errno to ENOSYS; this already happens on + the Hurd and on some Linux architectures. The Linux kernel + maintainers are discussing a more principled replacement for the + reused API. After a replacement becomes available, we will change + settimeofday to fail with ENOSYS on all platforms when its 'tzp' + argument is not a null pointer. + + settimeofday itself is obsolescent according to POSIX. Programs + that set the system time should use clock_settime and/or the adjtime + family of functions instead. We may cease to make settimeofday + available to newly linked binaries after there is a replacement for + Linux's time-zone-like offset API. + +hwclock had two calls to settimeofday, in functions to_sys_clock and +set_system_clock_timezone, where both the arguments to settimeofday +were valid (non-null). +Therefore, split the call, once for timezone and once for timeval. + +Fixes #12756 + +Upstream-Status: Pending + +Signed-off-by: Sakib Sajal +--- + util-linux/hwclock.c | 12 ++++++++---- + 1 file changed, 8 insertions(+), 4 deletions(-) + +diff --git a/util-linux/hwclock.c b/util-linux/hwclock.c +index 29f5102..088ab3b 100644 +--- a/util-linux/hwclock.c ++++ b/util-linux/hwclock.c +@@ -131,8 +131,10 @@ static void to_sys_clock(const char **pp_rtcname, int utc) + + tv.tv_sec = read_rtc(pp_rtcname, NULL, utc); + tv.tv_usec = 0; +- if (settimeofday(&tv, &tz)) +- bb_perror_msg_and_die("settimeofday"); ++ if (settimeofday(NULL, &tz)) ++ bb_perror_msg_and_die("settimeofday: timezone"); ++ if (settimeofday(&tv, NULL)) ++ bb_perror_msg_and_die("settimeofday: timeval"); + } + + static void from_sys_clock(const char **pp_rtcname, int utc) +@@ -283,8 +285,10 @@ static void set_system_clock_timezone(int utc) + gettimeofday(&tv, NULL); + if (!utc) + tv.tv_sec += tz.tz_minuteswest * 60; +- if (settimeofday(&tv, &tz)) +- bb_perror_msg_and_die("settimeofday"); ++ if (settimeofday(NULL, &tz)) ++ bb_perror_msg_and_die("settimeofday: timezone"); ++ if (settimeofday(&tv, NULL)) ++ bb_perror_msg_and_die("settimeofday: timeval"); + } + + //usage:#define hwclock_trivial_usage +-- +2.27.0 + -- cgit 1.2.3-korg
