* mgt.c (S_proc_dostop): If task_threads fails, resume the
suspended task.
|
|
|
|
* wait.c (S_proc_wait: reap): Set *PID_STATUS to CHILD->p_pid.
Reported by Neal H Walfield <neal@cs.uml.edu>.
|
|
* mgt.c (allocate_proc): Don't zero P->p_pi.

* wait.c (sample_rusage): New function.
(S_proc_mark_exit): Call it.
|
|
|
|
* proc.h (struct proc): New members p_rusage, p_child_rusage.
* wait.c (rusage_add): New static function.
(alert_parent): Use it to add dead child's p_rusage into parent's
p_child_rusage.
(S_proc_wait): Fill *RU out param with CHILD->p_rusage, not just zeros.
Rewrote subfunction child_ready and its two callers into new
subfunction reap to reduce duplicated code.
|
|
* mgt.c (process_has_exited): Call ports_interrupt_rpcs last thing.
|
|
|
|
* mgt.c (S_proc_reauthenticate): Release global_lock while making RPC.
Don't mach_port_deallocate an argument port when returning an error,
because mig does it for us.

* mgt.c (allocate_proc): Use memset instead of lots of 0 initializers.
|
|
|
|
* mgt.c (genpid): Rewritten.
|
|
* mgt.c (genpid): Before checking if NEXTPID is free, check if it
is greater than WRAP, and if yes, start over.
|
|
* host.c (S_proc_getexecdata): New variable PORTS_ALLOCATED.
Set it if we allocated a new buffer for PORTS. If it is set,
and allocation of a new buffer for INTS fails, unmap the buffer
for PORTS.
* host.c (S_proc_getexecdata): New variable I. Go over all
standard ports and increase the send right user reference by one.
Set *PORTSPOLY to MACH_MSG_TYPE_MOVE_SEND.
|
|
* info.c (S_proc_getprocinfo): If we return because mmap failed
for *PIARRAY, be sure to munmap THDS if necessary.
|
|
* host.c (initialize_version_info): Clear last byte of KV to make
sure that the string is null-terminated.
|
|
|
|
* proc.h (struct ids): Drop gids and ngids, we never use
them. Turn uids into a zero length array.

(ids_rele): New function. Drop a reference to the given
ids.

* main.c (main): Use ports_get_send_right.
|
|
|
|
* 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.

* stubs.c (struct msg_sig_post_request): New type, broken out of
send_signal, where it was anonymous.
(struct msg_spec): Type removed.
(blocking_message_send): Change type to any_t -> any_t.
Don't call cthread_wire; it's a no-op in GNU anyway.
Just return instead of calling cthread_exit.
Argument is now a pointer to struct msg_sig_post_request.
Check mach_msg return value for sanity assert.
(send_signal): Make MESSAGE auto instead of static, use new type name.
This problem tracked down by Mark Kettenis <kettenis@gnu.org>.
