* init.c (launch_core_servers): Don't use MOVE_SEND in Hurd RPCs.
|
|
* stubs.c (send_signal): Make MESSAGE auto instead of static.
Take new argument TIMEOUT, passed to mach_msg instead of zero.
(send_signal): For MACH_SEND_TIMED_OUT failure, destroy the
pseudo-received message to avoid leaking send rights.
* init.c (process_signal): Pass new argument, timeout of 500 ms.
|
|
* init.c (frob_kernel_process): Allocate the kernel's page in the
actual kernel task, not in our own. I wonder how this ever
worked. Also if we fail in that allocation, free the page we
allocated in our own space.
|
|
* init.c (notify_shutdown): Add const to argument type.
|
|
* init.c (frob_kernel_process): Use mmap instead of vm_allocate.
|
|
* init.c: Add #include <sys/mman.h> for munmap decl.
|
|
* init.c (reboot_system): Use munmap instead of vm_deallocate.
(frob_kernel_process): Likewise.
(kill_everyone): Likewise.
|
|
* init.c (open_console): Put this function inside [! SPLIT_INIT].
|
|
* init.c [SPLIT_INIT] (child_pid, child_task): New variables.
(process_signal, start_child, launch_something, launch_system): New
functions.
[! SPLIT_INIT] (system_state, shell_pid, rc_pid, launch_single_user,
process_rc_script, launch_multi_user, launch_system, kill_everyone,
kill_multi_user, process_signal): Variables and functions put inside
#ifndef SPLIT_INIT.
* stubs.c: New file, modified from ../proc/stubs.c.
* Makefile (SRCS): Remove ttys.c here.
[$(split-init) = yes] (SRCS): Add stubs.c
[$(split-init) = yes] (init-CPPFLAGS): New variable, -DSPLIT_INIT.
[$(split-init) = no] (SRCS): Add ttys.c only here.
[$(split-init) = no] (LDLIBS): Put defn (-lutil) under this test.

(launch_system): New function.
(S_startup_essential_task): Call it.
* init.c (global_argv): Make static.

* init.c (main): Barf if run in a normal Hurd environment (not boot).
* init.c (record_essential_task): Add missing return.

S_startup_essential_task.

Don't trim directory name from PROG for argument.

Move all the /etc/ttys handling stuff into a separate source file.
* init.c (_PATH_LOGIN, WINDOW_DELAY, struct terminal,
nttys, ttyslen, setup_terminal, add_terminal,
init_ttys, free_ttys, startup_terminal, startup_ttys,
find_line, restart_terminal, shutdown_terminal, reread_ttys): Move to
* ttys.c: ... here, new file.
* ttys.h: New file, declare external functions in ttys.c.
* Makefile (SRCS): Add ttys.c.
(OBJS): Derive from $(SRCS).

* init.c (request_dead_name): New function.
(S_startup_request_notification, S_startup_essential_task): Use it.
(run): Request dead-name notification for new task.
(main): Request dead-name notification for FSTASK.

FSTASK, AUTHTASK, PROCTASK specifically and crash with appropriate msg.
1999-06-04 Roland McGrath <roland@baalperazim.frob.com>
* init.c (launch_core_servers): Use proc_child on the proc server task
to register it with itself as our child. Snarf its proc port and use
proc_mark_exec do remove that unsightly `f', as we do for the other
bootstrap processes.
|
|
* init.c (frob_kernel_process): If no --kernel-command-line option,
try `getenv ("MULTIBOOT_CMDLINE")' before defaulting to "(kernel)".
|
|
* init.c (CRASH_FLAGS): Macro removed.
(crash_flags): New variable replaces it.
(crash_mach, crash_system): Use crash_flags instead of CRASH_FLAGS.
(options, parse_opt): Add --crash-debug/-H, to set crash_flags to
RB_DEBUGGER.
|
|
* init.c (kernel_command_line): New variable.
(frob_kernel_process): New function.
(S_startup_essential_task): Call it after init_stdarrays.
(options): Add --kernel-command-line/-K option.
(parse_opt): Grok -K, set kernel_command_line.
|
|
* init.c (do_mach_notify_dead_name): Deallocate the extra
reference to NAME that the notification carries.
|
|
* init.c (shutdown_terminal): Revoke access to the terminal from
existing programs.
|
|
* init.c (main): Don't bogusly clear bootstrap_args.
Reported by OKUJI Yoshinori <okuji@kuicr.kyoto-u.ac.jp>.
|
|
* init.c (setup_terminal): Free LINE after done using it.

Both reported by Katusya Tanaka (wyvern@pb3.so-net.ne.jp).
