+
+	* Makefile (exec): Link against fshelp too now.
+
+	* exec.c (do_exec): Call proc_setowner *after* possible
+ 	proc_reassign; otherwise it modifies the stub process's state and

+

+
+Wed Jun 12 21:17:33 1996  Michael I. Bushnell, p/BSG  <mib@gnu.ai.mit.edu>

+ 	its threads and deallocating its address space.
+
+Tue Apr 30 11:36:25 1996  Michael I. Bushnell, p/BSG  <mib@gnu.ai.mit.edu>
+
+	* exec.c (check_gzip) [ziprderr]: Treat all read errors as
+ 	ENOEXEC.  First off, because that's what they are; also because
+ 	some callers of read_error don't set errno at all.

+	* exec.c (S_exec_exec): Use strdupa().  Also update use of
+	hurd_file_name_lookup() [still probably not right though].
+
+Thu Jan 11 15:36:18 1996  Miles Bader  <miles@gnu.ai.mit.edu>
+
+	* hashexec.c (check_hashbang): When using executable name found on

+
+Fri May 27 01:40:04 1994  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)
+
+	* exec.c (servercopy): New function to check the servercopy flag
+	and possibly vm_allocate a copy of argument data.

+	and INTARRAY.
+	(S_exec_exec): Take those new args and pass them to do_exec.
+	(S_exec_setexecdata): Take new args PORTS_COPY and INTS_COPY.
+	Use servercopy for PORTS and INTS.

+
+Tue May 24 01:05:08 1994  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)
+
+	* exec.c (struct bootinfo): Remove members argv_vmalloc, envp_vmalloc.
+	(do_exec): Don't set BOOT->argv_vmalloc or BOOT->envp_vmalloc.  If
+	ARGV_COPY is set, vm_allocate space for ARGV; likewise for
+	ENVP_COPY and ENVP.
+	(S_exec_startup): Don't test BOOT->argv_vmalloc and
+	BOOT->envp_vmalloc; BOOT->argv and BOOT->envp are always vm_allocate'd.
+	(do_mach_notify_no_senders): Likewise.

+
+Mon May 23 22:01:11 1994  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)
+
+	* exec.c (S_exec_exec): Reverse args to memmem.
+	(do_exec): Don't vm_deallocate DEALLOCNAMES or DESTROYNAMES; mig

+
+	* exec.c (S_exec_init): Don't deallocate host_priv until after

+
+	* Makefile (exec.o): Add dependencies on fsys_S.h and notify_S.h.
+	(fsysServer.c, notifyServer.c): Notice that these rules build
+	fsys_S.h and notify_S.h respectively.
+
+Mon May  9 17:06:52 1994  Michael I Bushnell  (mib@geech.gnu.ai.mit.edu)
+
+	* exec.c (exec_version, save_argv): New variable.
+	(main): Set save_argv.
+	(S_exec_init): Give the real argv to proc.

+	mach_setup_thread.
+	(S_exec_exec): Pass msg type arg for FILE arg to exec_exec.

+
+	* exec.c (do_exec): For a newtask exec when EXEC_SECURE is not set
+	and OLDTASK is not null, send the `task_create' RPC on OLDTASK
+	rather than mach_task_self ().
