Subject: [LTP] [PATCH] include/tst_timer.h: Fix overflows
Date: Mon, 18 Jan 2021 11:42:26 +0100 [thread overview]
Message-ID: <YAVmErn6g+dCfSEr@pevik> (raw)

Hi Cyril,
> This fixes overflows in tst_timeval_to_us() and tst_timeval_to_ns() on
> 32bit hardware. We have to cast the tv_sec (ulong) to (long long)
> explicitly otherwise the tv_sec will overflow the multiplication.
> This fixes clock_gettime04 where the overflow corrupted the result from
> gettimeofday() when it was converted from timeval to timespec.
