The X server frequently deals with SIGIO and SIGALRM interruptions. If process execution is inside certain blocking system calls when these signals arrive, e.g. with the kernel blocked on a contended semaphore, the system calls will be interrupted. Some system calls are automatically restartable (the kernel re-executes them with the same parameters once the signal handler returns) but only if the signal handler allows it. Set SA_RESTART on the signal handlers to enable this convenient behaviour. Reviewed-by: Adam Jackson <ajax@redhat.com> Signed-off-by: Daniel Drake <drake@endlessm.com> |
