We have a winner. If I revert all of the meaningful changes to
linux_clone, things still work. Reverting just the
'Make this runnable after we are finished with it' changes:
/*
* Make this runnable after we are finished with it.
*/
p2->p_stat = SRUN;
setrunqueue(p2);
p->p_retval[0] = p2->p_pid;
p->p_retval[1] = 0;
lead to the jvm seg-faulting. Going back to rfork/pfind from fork1
leads to a runnable jvm.
Hmm.. something appears to be hosed about whoami:
<9:32am>monet/gallatin:/tmp>whoami
gallatin
<9:32am>monet/gallatin:/tmp>/compat/linux/usr/bin/whoami
root
This worked fine pre-patch & ktrace's look identical.
I'm about out of time for now...
