Revision 8cd9da85d2bd87ce889043e7b1735723dd10eb89 authored by Frederic Weisbecker on 13 September 2021, 14:53:32 UTC, committed by Thomas Gleixner on 23 September 2021, 09:53:51 UTC
Resetting/stopping an itimer eventually leads to it being reprogrammed
with an actual "0" value. As a result the itimer expires on the next
tick, triggering an unexpected signal.
To fix this, make sure that
struct signal_struct::it[CPUCLOCK_PROF/VIRT]::expires is set to 0 when
setitimer() passes a 0 it_value, indicating that the timer must stop.
Fixes: 406dd42bd1ba ("posix-cpu-timers: Force next expiration recalc after itimer reset")
