	* exec.c (check_gzip) [ziprderr]: Treat all read errors as

	* exec.c (check_section): If the format makes no sense, return

	* hashexec.c (check_hashbang): When using executable name found on
	the path, don't return alloca()ed memory from search_path(); use
	malloc() instead.
	Use envz_get() to search the environment.

	* exec.c (S_exec_exec): Use envz_get() to search the environment.

	Include "notify_S.h".

Tue Jul 19 20:51:58 1994  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

	* Makefile (exec_server.h execServer.c, fsys_S.h fsysServer.c):
	Find .defs file in ../hurd, not $(includedir).

	VM_PROT.  If vm_write of overlap page gets KERN_PROTECTION_FAILURE,

	* a.out.h (struct exec): Type removed.
	(OMAGIC, NMAGIC, ZMAGIC, N_MAGIC, N_MACHTYPE, N_BADMAG): Macros
	removed.  Just #include "a.out.gnu.h" to get all these defined.

	* Makefile (DIST_FILES): Add a.out.gnu.h.
	(exec.o, hostarch.o): Depend on a.out.gnu.h.

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.
	(do_exec): Take new args DTABLE_COPY, PORTARRAY_COPY,
	INTARRAY_COPY.  Use servercopy for ARGV, ENVP, DTABLE, PORTARRAY,
	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.
	(S_exec_startup): Never copy from info in *BOOT, always just set
	the argument pointers to the pointers in *BOOT.  MiG will copy and
	deallocate the space as necessary.

	* exec.c (check): Lock and unlock E->cntl->lock properly.
	(finish_mapping): New function, broken out of finish.
	(postload_section): New function, broken out of load_section.
	(postload): New function, like load but calls postload_section.

	* 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.
	(load_section): Handle non-bss sections that are not page aligned.

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
	deallocates the space for us.

Tue May 17 13:33:41 1994  Michael I Bushnell  (mib@churchy.gnu.ai.mit.edu)

	* 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.
	Call proc_register_version if we can.
	(S_exec_init): Call startup_essential_task if we can.

	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 ().
