CVS commit: [netbsd-5-1] src/sys/kern
Module Name:src Committed By: snj Date: Sat Nov 7 20:42:59 UTC 2015 Modified Files: src/sys/kern [netbsd-5-1]: kern_exec.c kern_exit.c kern_synch.c Log Message: Pull up following revision(s) (requested by pgoyette in ticket #1979): sys/kern/kern_synch.c: revision 1.309 sys/kern/kern_exit.c: revisions 1.246, 1.247 sys/kern/kern_exec.c: revision 1.419 In execve_runproc(), update the p_waited entry for the process being moved to SSTOP state, not for its parent. (It is correct to update the parent's p_nstopchild count.) If the value is not already zero, it could prevent its parent from waiting for the process. Fixes PR kern/50298 -- When clearing out the scheduler queues during system shutdown, we move all processes to the SSTOP state. Make sure we update each process's p_waited and the parents' p_nstopchild counters to maintain consistent values. Should not make any real difference this late in the shutdown process, but we should still be consistent just in case. Fixes PR kern/50318 -- Currently, if a process is exiting and its parent has indicated no intent of reaping the process (nor any other children), the process wil get reparented to init. Since the state of the exiting process at this point is SDEAD, proc_reparent() will not update either the old or new parent's p_nstopchild counters. This change causes both old and new parents to be properly updated. Fixes PR kern/50300 -- For processes marked with PS_STOPEXIT, update the process's p_waited value, and update its parent's p_nstopchild value when marking the process's p_stat to SSTOP. The process needed to be SACTIVE to get here, so this transition represents an additional process for which the parent needs to wait.

In that case, we don't want to adjust the parent's p_nstopchild count. Found by Robert Elz.
