Timing differences look improbable. Because before this series /sbin/init always ignored SIGSTOP. Now, ptracer does PTRACE_ATTACH and exits without clearing the pending SIGSTOP. init dequeues this signal and becomes TASK_STOPPED. Consider: $ sleep 1000 & [1] 875 $ grep State: /proc/`pidof sleep`/status State: S (sleeping) $ perl -e 'syscall 101, 16, 0+shift, 0,0' `pidof sleep` # just PTRACE_ATTACH + exit [1]+ Stopped sleep 1000 $ grep State: /proc/`pidof sleep`/status State: T (stopped) This is the "normal" behaviour, afaics the same happens with init now.

Timing differences look improbable. It's the change from !signal_group_exit(signal) to !sig_kernel_only(signr) and quite frankly, I still don't see the point. The comment seems to be wrong too: If SIGSTOP/SIGKILL originate from a descendant of container-init they are never queued (i.e dropped in sig_ignored() in an earler patch). If SIGSTOP/SIGKILL originate from parent namespace, the signal is queued and container-init processes the signal. since the bug was that the SIGSTOP (from within the same container) was _not_ ignored like the comment says.

Previously, !signal_group_exit(signal) meant: we do not know what should we do, let's ignore this signal. Unless the multithreaded init does exec, in this case we should respect SIGKILL. With the recent changes, sig_kernel_only() means: we already checked we should handle SIGKILL/SIGSTOP when this signal was queued. > The comment seems to be wrong too: > > If SIGSTOP/SIGKILL originate from a descendant of container-init they are > never queued (i.e dropped in sig_ignored() in an earler patch). > > If SIGSTOP/SIGKILL originate from parent namespace, the signal is queued > and container-init processes the signal. > > since the bug was that the SIGSTOP (from within the same container) was > _not_ ignored like the comment says. Yes, the changelog could be better because it ignores ptrace issues. But this was discussed, >From http://marc.info/?t=123222433100001 Yes we should handle SIGSTOP fine if it sent from the parent namespace. Also. Currently it is possible to ptrace the global init, but even ptracer can't stop it (but ptrace_stop() works). With these patches ptracer can stop init. I forgot to mention this behaviour change, imho this side-effect is good. So, at least this change is not "by accident". Oleg. ^ permalink raw reply [flat|nested] 10+ messages in thread
