Tue Mar  9 13:11:43 1999  Thomas Bushnell, BSG  <tb@mit.edu>

	* 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.

Sun Mar  7 18:19:07 1999  Thomas Bushnell, BSG  <tb@mit.edu>

	* 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.

1999-03-06  Mark Kettenis  <kettenis@gnu.org>

	* notify.c (do_mach_notify_dead_name): Deallocate reference to
	DEADPORT.

Sat Feb 20 06:26:17 1999  Thomas Bushnell, BSG  <tb@mit.edu>

	* stubs.c (send_signal): Typo in comment.

	* cpu-types.c: Test with #ifdef for CPU_TYPE_I486, CPU_TYPE_PENTIUM,
	CPU_TYPE_PENTIUMPRO, CPU_TYPE_POWERPC, since not all <mach/machine.h>
	versions have them.

Tue Sep 16 15:26:04 1997  Thomas Bushnell, n/BSG  <thomas@gnu.ai.mit.edu>

	* host.c (initialize_version_info): Construct UNAME_INFO.machine
	with a dash instead of a slash so that it can be used as a file
	name component.

	* host.c (initialize_version_info): Copy our version into element
	0 of server_versions, not element 1.  Use HURD_VERSION instead of
	OUR_VERSION.  Use literal "proc" instead of OUR_SERVER_NAME.
	* proc.h (OUR_SERVER_NAME, OUR_VERSION): Delete macro.

	actually returning thread details (a lone PI_FETCH_THREADS simply
	means "number of threads").  React to errors somewhat more gracefully.

	pid_find_allow_zombie, not ordinary pid_find.

	* mgt.c (S_proc_reassign): Use new ports_transfer_right call
 	instead of claim/install sequence; the latter has leaves the port
 	out of any hash table for a time, which produces a race with
 	incoming messages.

	* mgt.c (S_proc_reassign): Rather than getting a new request port,
	preserve STUBP's request port.  This is more convenient for
	users (and equally good security), and it's what the protocol spec
	says anyway.

Tue Aug 30 12:44:37 1994  Michael I Bushnell  <mib@geech.gnu.ai.mit.edu>

	* primes.c: Replaced file with new version from Jim Blandy

Mon Aug 22 13:29:21 1994  Roland McGrath  <roland@churchy.gnu.ai.mit.edu>

	to create a send right from P->p_reqport.

	* main.c (main): Removed var `authhandle'.  Use global
	`authserver' instead.

Wed Aug 17 14:02:31 1994  Michael I Bushnell  <mib@geech.gnu.ai.mit.edu>

	* host.c (init_stdarrays): Removed function.

	PID check before returning startup_proc's wait.]
	(alert_parent): Likewise.  [Incorrect semantics were in
	PID check before returning P->p_parent's wait.]

	it passes the PID test.

	* pgrp.c (S_proc_setpgrp): Don't do process group change if we are
	changing into our own process group.
	* mgt.c (S_proc_child): Likewise.

	has died (there's a race between pending requests and processing
	of dead-name notifications) then convert MACH_SEND_INVALID_DEST to

	space for the null too.

	* mgt.c (process_has_exited): delete unused variable LAST.
	* msg.c (check_message_return): delete unused variables I,
	MSGPORTS, and CP.  Changed type of second arg to `void *'
