All rights reserved. - * - * bootstrap.defs -- Mig interface definition */ subsystem bootstrap 400; -/* - * Interface: Bootstrap server - * - * The bootstrap server is the first user-mode task initiated by the Mach - * kernel at system boot time. The bootstrap server provides two services, - * it initiates other system tasks, and manages a table of name-port bindings - * for fundamental system services (e.g. lookupd, Window Manager, etc...). - * - * Name-port bindings can be established with the bootstrap server by either - * of two mechanisms: - * - * 1. The binding can be indicated, in advance of the service that backs it - * being available, via a "service create" request. In this case, bootstrap - * will immediately create a port and bind the indicated name with that port. - * At a later time, a service may "checkin" for the name-port - * binding and will be returned receive rights for the bound port. Lookup's - * on bindings created by this mechanism will return send rights to the port, - * even if no service has "checked-in". In this case, requests sent to the - * bound port will be queued until a server has checked-in and can satisfy the - * request. - * - * 2. Bindings can be established dynamically via a "register" request. In - * this case, the register request provides bootstrap with a name and send - * rights for a port. Bootstrap will provide send rights for the bound port - * to any requestor via the lookup request. - * - * Bootstrap provides its service port to descendant tasks via the Mach - * "bootstrap" special task port. All direct descendants of bootstrap receive - * a "privileged" bootstrap service port. System services that initiate - * untrusted tasks should replace the Mach bootstrap task special port with - * a subset bootstrap port to prevent them from infecting the namespace. - * - * The bootstrap server creates a "backup" port for each service that it - * creates. This is used to detect when a checked out service is no longer - * being served. The bootstrap server regains all rights to the port and - * it is marked available for check-out again. This allows crashed servers to - * resume service to previous clients. Lookup's on this named port will - * continue to be serviced by bootstrap while holding receive rights for the - * bound port. A client may detect that the service is inactive via the - * bootstrap status request. If an inactive service re-registers rather - * than "checking-in" the original bound port is destroyed. - * - * The status of a named service may be obtained via the "status" request. - * A service is "active" if a name-port binding exists and receive rights - * to the bound port are held by a task other than bootstrap. - * - * The bootstrap server may also (re)start server processes associated with - * with a set of services. The definition of the server process is done - * through the "create server" request. The server will be launched in the - * same bootstrap context in which it was registered. - */ - #include #include -import ; +import "bootstrap_public.h"; +import "bootstrap_private.h"; +type pid_t = integer_t; type cmd_t = c_string[512]; -type name_t = c_string[128]; type cmd_array_t = ^array [] of cmd_t; +type name_t = c_string[128]; type name_array_t = ^array [] of name_t; +type _internal_string_t = ^array [] of char; type bootstrap_status_t = integer_t; type bootstrap_status_array_t = ^array [] of bootstrap_status_t; +userprefix raw_; serverprefix x_; -/* - * kern_return_t - * bootstrap_create_server(mach_port_t __bs_port, - * cmd_t __server_command, - * natural_t __server_uid, - * boolean_t __on_demand, - * mach_port_t *__server_port) - * - * Declares a server that mach_init will re-spawn within the specified - * bootstrap context.

The bootstrap server provides two services, + * it initiates other system tasks, and manages a table of name-port bindings + * for fundamental system services (e.g. lookupd, Window Manager, etc...). + * + * Name-port bindings can be established with the bootstrap server by either + * of two mechanisms: + * + * 1. The binding can be indicated, in advance of the service that backs it + * being available, via a "service create" request. In this case, bootstrap + * will immediately create a port and bind the indicated name with that port. + * At a later time, a service may "checkin" for the name-port + * binding and will be returned receive rights for the bound port. Lookup's + * on bindings created by this mechanism will return send rights to the port, + * even if no service has "checked-in". In this case, requests sent to the + * bound port will be queued until a server has checked-in and can satisfy the + * request. + * + * 2. Bindings can be established dynamically via a "register" request. In + * this case, the register request provides bootstrap with a name and send + * rights for a port. Bootstrap will provide send rights for the bound port + * to any requestor via the lookup request. + * + * Bootstrap provides its service port to descendant tasks via the Mach + * "bootstrap" special task port. All direct descendants of bootstrap receive + * a "privileged" bootstrap service port. System services that initiate + * untrusted tasks should replace the Mach bootstrap task special port with + * a subset bootstrap port to prevent them from infecting the namespace. + * + * The bootstrap server creates a "backup" port for each service that it + * creates. This is used to detect when a checked out service is no longer + * being served. The bootstrap server regains all rights to the port and + * it is marked available for check-out again. This allows crashed servers to + * resume service to previous clients. Lookup's on this named port will + * continue to be serviced by bootstrap while holding receive rights for the + * bound port. A client may detect that the service is inactive via the + * bootstrap status request. If an inactive service re-registers rather + * than "checking-in" the original bound port is destroyed. + * + * The status of a named service may be obtained via the "status" request. + * A service is "active" if a name-port binding exists and receive rights + * to the bound port are held by a task other than bootstrap. + * + * The bootstrap server may also (re)start server processes associated with + * with a set of services.

When this shell -dies, either because the user logged out -or an abnormal termination occurred (a signal), -the -.Nm init -program wakes up, deletes the user -from the -.Xr utmp 5 -file of current users and records the logout in the -.Xr wtmp -file. -The cycle is -then restarted by -.Nm init -executing a new -.Xr getty -for the line. -.pl +1 -.Pp -Line status (on, off, secure, getty, or window information) -may be changed in the -.Xr ttys -file without a reboot by sending the signal -.Dv SIGHUP -to -.Nm init -with the command -.Dq Li "kill \-s HUP 1" . -On receipt of this signal, -.Nm init -re-reads the -.Xr ttys -file. -When a line is turned off in -.Xr ttys , -.Nm init -will send a SIGHUP signal to the controlling process -for the session associated with the line. -For any lines that were previously turned off in the -.Xr ttys -file and are now on, -.Nm init -executes a new -.Xr getty -to enable a new login. -If the getty or window field for a line is changed, -the change takes effect at the end of the current -login session (e.g., the next time -.Nm init -starts a process on the line). -If a line is commented out or deleted from -.Xr ttys , -.Nm init -will not do anything at all to that line. -However, it will complain that the relationship between lines -in the -.Xr ttys -file and records in the -.Xr utmp -file is out of sync, -so this practice is not recommended. -.Pp -.Nm Init -will terminate multi-user operations and resume single-user mode -if sent a terminate -.Pq Dv TERM -signal, for example, -.Dq Li "kill \-s TERM 1" . -If there are processes outstanding that are deadlocked (because of -hardware or software failure), -.Xr init -will not wait for them all to die (which might take forever), but -will time out after 30 seconds and print a warning message. -.Pp -.Nm Init -will cease creating new -.Xr getty Ns 's -and allow the system to slowly die away, if it is sent a terminal stop -.Pq Dv TSTP -signal, i.e. -.Dq Li "kill \-s TSTP 1" . -A later hangup will resume full -multi-user operations, or a terminate will start a single user shell. -This hook is used by -.Xr reboot 8 -and -.Xr halt 8 . -.Pp -The role of -.Nm init -is so critical that if it dies, the system will reboot itself -automatically. -If, at bootstrap time, the -.Xr init -process cannot be located, the system will panic with the message -``panic: "init died (signal %d, exit %d)''. -.Sh DIAGNOSTICS -.Bl -diag -.It "getty repeating too quickly on port %s, sleeping" -A process being started to service a line is exiting quickly -each time it is started. -This is often caused by a ringing or noisy terminal line. -.Em "Init will sleep for 10 seconds" , -.Em "then continue trying to start the process" . -.Pp -.It "some processes would not die; ps axl advised." -A process -is hung and could not be killed when the system was shutting down. -This condition is usually caused by a process -that is stuck in a device driver because of -a persistent device error condition. -.El -.Sh FILES -.Bl -tag -width /var/log/wtmp -compact -.It Pa /dev/console -System console device. -.It Pa /dev/tty* -Terminal ports found in -.Xr ttys . -.It Pa /var/run/utmp -Record of Current users on the system. -.It Pa /var/log/wtmp -Record of all logins and logouts. -.It Pa /etc/ttys -The terminal initialization information file. -.It Pa /etc/rc -System startup commands. -.El -.Sh SEE ALSO -.Xr login 1 , -.Xr kill 1 , -.Xr sh 1 , -.Xr ttys 5 , -.Xr crash 8 , -.Xr getty 8 , -.Xr rc 8 , -.Xr reboot 8 , -.Xr halt 8 , -.Xr shutdown 8 -.Sh HISTORY -A -.Nm -command appeared in -.At v6 . -.Sh BUGS -Systems without -.Xr sysctl -behave as though they have security level \-1. diff --git a/launchd/src/init.c b/launchd/src/init.c index 05abab3..83be58a 100644 --- a/launchd/src/init.c +++ b/launchd/src/init.c @@ -1,25 +1,21 @@ /* * Copyright (c) 1999 Apple Computer, Inc.
