work in proc0.
Remove the TDP_WAKEPROC0 workaround.

Only check signal event, single threading event shouldn't be reported.

Clear P_STATCHILD earlier to avoid unnecessary retrying.

Fix a race condition between kern_wait() and thread_stopped().

2005-04-19T08:07:28+00:00

Problem is in kern_wait(), parent process steps through children list,
once a child process is skipped, and later even if the child is stopped,
parent process still sleeps in msleep(), the race happens if parent
masked SIGCHLD.

Introduce p_canwait() and MAC Framework and MAC Policy entry points

2005-04-18T13:36:57+00:00

mac_check_proc_wait(), which control the ability to wait4() specific
processes.  This permits MAC policies to limit information flow from
children that have changed label, although has to be handled carefully
due to common programming expectations regarding the behavior of
wait4().  The cr_seeotheruids() check in p_canwait() is #if 0'd for
this reason.

The mac_stub and mac_test policies are updated to reflect these new
entry points.
