2011-08-11Fix spurious port deallocationSamuel Thibault
* proc/mgt.c (S_proc_exception_raise): On proc_exception_raise forwarding error, return MIG_NO_REPLY instead of 0, since the reply port may have been consumed, and the task is being terminated anyway.

* mgt.c (S_proc_dostop): Revert last change.
2003-08-092003-06-16 Ognyan Kulev <ogi@fmi.uni-sofia.bg>Marcus Brinkmann
* mgt.c (S_proc_dostop): Instead of suspending all threads except CONTTHREAD, first suspend all threads, and then resume CONTTHREAD.

* mgt.c (S_proc_exception_raise): Check for MACH_SEND_NOTIFY_IN_PROGRESS rather than MACH_SEND_INVALID_NOTIFY. Don't deallocate THREAD and TASK ports before the switch, since the successful case uses THREAD again and the failure case uses TASK again. Instead, deallocate them at the end of the successful case. At the end of the error case, use mach_port_destroy on THREAD only.

* mgt.c (S_proc_reassign): Remove unused variable FOO.
1999-03-121999-03-11 Mark Kettenis <kettenis@gnu.org>Thomas Bushnell
* notify.c (do_mach_notify_dead_name): Remove unnecessary braces. * msg.c (S_proc_setmsgport): Remove unused variable FOO. (S_proc_getmsgport): Only check if the message port is still alive if it is not MACH_PORT_NULL. Use mach_port_type instead of mach_port_get_refs to check if the port is dead. * mgt.c (S_proc_reassign): Use mach_port_destroy to release the old task port.
1999-03-09Tue Mar 9 13:11:43 1999 Thomas Bushnell, BSG <tb@mit.edu>Thomas Bushnell
* notify.c (do_mach_notify_dead_name): Don't check against P->p_msgport anymore. * msg.c (message_port_dead): Delete function. (S_proc_setmsgport): Don't request a dead-name notification anymore. (S_proc_getmsgport): Check to see if P->p_msgport is dead before returning it. * mgt.c (S_proc_reassign): Only use mach_port_deallocate to release P->msgport. (process_has_exited): Likewise. * proc.h (message_port_dead): Delete prototype.
1999-03-09Tue Mar 9 13:11:43 1999 Thomas Bushnell, BSG <tb@mit.edu>Thomas Bushnell
* mgt.c (S_proc_reassign): It's not necessary to re-request the task-death notification; we've moved both the task right and the proc port that gets the notification, so delete that. * mgt.c (S_proc_reassign): Use mach_port_destroy instead of mach_port_deallocate to release P->p_msgport, for the same reasons as the changes below.
1999-03-07Sun Mar 7 18:19:07 1999 Thomas Bushnell, BSG <tb@mit.edu>Thomas Bushnell
* mgt.c (process_has_exited): Use mach_port_destroy instead of mach_port_deallocate to release P->p_msgport. (complete_exit): Likewise for P->p_task. These changes eliminate a race; we are destroying the receiver of the dead-name notifications on these ports, but if that means we lose a notification, then the ref-count on the name will get incremented and we can't re-decrement it since we never hear the notification.

* mgt.c (add_tasks): Fix vm_deallocate call to use mach_task_self () instead of mach_host_self ().
1996-07-08(S_proc_reauthenticate): Don't use unsafe MOVE_SEND in user-sideMichael I. Bushnell
interruptible RPC.
1996-07-03(process_has_exited): When reparenting children to init, if one ofMichael I. Bushnell
them is dead, alert init.
1996-05-24(process_has_exited): Don't call alert_parent if P->p_task is nullMichael I. Bushnell
(which happens only if this is the stub process in proc_reassign). This because the parent is uninvolved in the death of stubp.
1996-05-10(S_proc_exception_raise): Fetch sigcode from correctly named member ofMichael I. Bushnell
HSD.
1996-05-09(S_proc_reauthenticate): Use new authentication interface.Michael I. Bushnell
(S_proc_setowner): Expect and interpret new CLEAR parm. (S_proc_exception_raise): Set P->p_sigcode; use new _hurd_exception2signal args.
1996-04-15(process_has_exited): Clear p->p_waited.Michael I. Bushnell
1996-03-29(S_proc_reassign): Use new ports_transfer_right call instead ofMichael I. Bushnell
claim/install sequence; the latter has leaves the port out of any hash table for a time, which produces a race with incoming messages.
1996-03-21(new_proc): Oops, reinstall code to request dead name notification onMichael I. Bushnell
the task port.
1996-03-20(complete_exit): Leave pgrp here.Michael I. Bushnell
(process_has_exited): Not here.

1996-02-09(S_proc_exception_raise): Rewritten.Roland McGrath
(S_proc_handle_exceptions): Don't set E->replyport. (S_proc_exception_raise_reply): Function removed.
1995-12-20(S_proc_reassign):Miles Bader
Have notifications sent to the correct request port. Once we've given STUBP's request port to P, don't leave it in STUBP, so process_has_exited() doesn't dealloc it.
1995-12-20(new_proc): Don't set P->p_noowner for processes 0 and 1.Michael I. Bushnell
1995-12-19(S_proc_reauthenticate): Reverse miles' last chonge.Michael I. Bushnell
1995-12-19(S_proc_reauthenticate): Don't return 0 for the new port.Miles Bader
