	* mgt.c (S_proc_getallpids): Don't dereference PIDS in call
	to vm_allocate.

Mon Oct 10 02:18:02 1994  Roland McGrath  <roland@churchy.gnu.ai.mit.edu>

	* host.c (rebuild_uname): If all the server versions after [0]
	(the microkernel) match, merge them all into one "Hurd-VERSION"
	element in the uname version string.

	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>

	* wait.c (S_proc_mod_stopchild): Negate VALUE; sense of
	p_nostopcld flag is opposite of flag value described in process.defs.

	* pgrp.c (S_proc_getpgrppids): Understand PGID of zero as meaning
	caller's pgrp.

	* mgt.c (S_proc_child): Check CHILDP->p_msgport against

	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.

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

	* wait.c (S_proc_wait): Only return wait on stopped child if
	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.

	calls to thread_info (just pretend it never existed).

	* info.c (get_string, get_vector, S_proc_getprocinfo): If the task
	has died (there's a race between pending requests and processing
	of dead-name notifications) then convert MACH_SEND_INVALID_DEST to
	ESRCH.

	(get_string_array): Set BP before the loop.  Use a for loop that
	iterates over elts in VECTOR.  Fix check of LEN to reallocate buffer.
	(S_proc_getprocargs): Cast BUF to vm_address_t * for get_string_array.
	(get_vector): Fix pointer arithmetic; break out of loop when done.
	Check for error from malloc.

	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 *'

	* wait.c, host.c, info.c, mgt.c, notify.c, pgrp.c: Changed MiG
	server stubs' return types from error_t to kern_return_t; the
