Oleg Nesterov 108150ea78 [PATCH] posix-timers: fix cleanup_timers() and run_posix_cpu_timers() races ... 1. cleanup_timers() sets timer->task = NULL under tasklist + ->sighand locks. That means that this code in posix_cpu_timer_del() and posix_cpu_timer_set() lock_timer(timer); if (timer->task == NULL) return; read_lock(tasklist); put_task_struct(timer->task) is racy. With this patch timer->task modified and accounted only under timer->it_lock. Sadly, this means that dead task_struct won't be freed until timer deleted or armed. 2. run_posix_cpu_timers() collects expired timers into local list under tasklist + ->sighand again. That means that posix_cpu_timer_del() should check timer->it.cpu.firing under these locks too.
