Joachim Nilsson 577622c945 Add support for calling initctl with process name as well as JOBID
This patch makes it possible to communicate process name or JOB[:ID]
from initctl to Finit.  When the process name translates into a service
with multiple instances Finit applies the requested command to all
instances.  For example, two Dropbear SSH services running on two
different ports, calling `initctl stop dropbear` stops both services.

Joachim Nilsson 1a1f24721f Refactor: introduce telinit and a new initctl tool w/ API
- Reduce size of `helpers.c`, for linking against new `initctl` tool,
  by moving out functions to `pid.c` and `exec.c`
- Add `AF_UNIX` API to Finit, to complement old `/dev/initctl` FIFO
- Let old FIFO API be used by init/telinit: `init <q | 1-9>`
- Move all advanced initctl code from `client.c` to `initctl.c`, yes
  its a bit confusing to call the *new* tool the same as the old FIFO
  but this is more in line with what, e.g Upstart does.
- Move all advanced server side code from `plugins/initctl.c` to `api.c`
- Update TODO with upcoming inetd syntax change and dynamic events.
- Temporarily fix display of inetd services from `initctl status -v`

Joachim Nilsson 2026486fda Refactor: Cleanup and expand client code to support <version|q|reload|debug>
Further refactoring of the client code.  Supported commands:

- debug:   Toggle PID 1 debug flag
- version: Show Finit version or custom header string
- reload:  Reload config files in /etc/finit.d/, same as SIGHUP

Also supported is the legacy 'init q' command, to reload config.

The 'status' command now supports an optiona '-v', either as an
argument to init itself, or as argument to the command.  When it
is given 'status' lists verbose information about all services.
Currently only the service arguments are listed.

Joachim Nilsson cb075560ed Add support for multiple instances of the same command
This patch adds support for starting and supervising multiple
services (run, task, or service) using an extra #ID number.

service #1 [2345] /sbin/httpd -f -h /http -p 80   -- Web server
service #2 [2345] /sbin/httpd -f -h /http -p 8080 -- Old web server

Also included in this patch is a fix for endless respawn of faulty
services.  For instance, a buggy daemon that crashes repeatedly will now
be stopped after 10 respawns.

Joachim Nilsson 25cc9f3b9b Improve runlevel support by adding a bootstrap phase, also adds task/run cmd
Most systems need an early bootstrap phase for one-shot tasks and
necessary one-time probing.  This phase usually runs well before any
networking is setup.  This commit adds support for that 'S' runlevel,
and also extends the number of possible total runlevels to nine.

For the one-shot tasks that run in bootstrap two new finit.conf cmds
have been added:

   - task: For one-shot tasks that can be started in parallell
   - run:  For one-shot tasks that must run in sequence

Joachim Nilsson f29d2733c7 Fix incorrect use of variable arguments in run_parts() and simplify code
The run_parts() implementation used variable arguments in a bad way,
resulting in it not working properly.  Replaced va_*() code with a
simple cmd argument that's passed to each script called.

Also, the opendir()/readdir() code has been replaced with scandir()
using regular alphasort(). This simplifies the code somewhat as well.

Otherwise, minor cleanups.

Joachim Nilsson 65c9e7ebc6 Fix I/O plugin watcher, load plugins earlier to enable a new early hook!
Restructure start by calling the plugin loader earlier. This makes it
possible to run hooks even earlier.  This also adds a new hook:
HOOK_ROOTFS_UP which runs as soon as the system root (/) is available.

Another very notable change is the slow refactor of helpers.c into a finit
helper library called libite.so (-lite). This is a light-weight

Also, lots of misc. fixes all over the place. Signal handling still really
needs to be looked into once more!

Makefile:
        Add dependency handling for parallell build
        Add libite library

ChangeLog:
        Update with new 1.4 release. There is a lot of fixes!

libite/:
        Collection of utility functions and C library extensions for
        finit & its plugins

reboot.c:
        New reboot tool. Simply sends SIGINT to PID 1

finit.h:
        Cleanup old LISTEN_INITCTL define, code is in an optional plugin now

finit.c:
        Let mdev/udev run *after* cls()
        Add useful debug statement for /proc/cmdline
        Earlier plugin load => new early hook point
        Show OK/FAIL for total plugin load, not for each plugin => speedup

helpers.h:
        Rename syslog macros to prevent common name clashes (DEBUG/ERROR)
        Add __FILE__ to _e(), _d() and _pe() macros

helpers.c:
        In ifconfig() the addr and mask arguments are now optional
        The copyfile() has been moved to libite.so
        Temporarily remove const directive from some functions to build
        Use DFLSIG() macro in run_getty() to simplify code

plugin.h:
        Add new HOOK_ROOTFS_UP hook

plugin.c:
        Fix init_plugins() to actually register the plugin's I/O fd
        Skip verbose listing of all plugins in plugin_load_all()

svc.c:
        svc_start(): Dito

plugins/Makefile:
        Inherit CFLAGS and LDFLAGS, but make sure to filter out -rdynamic
        from LDFLAGS, it's used by the daemon, only

plugins/initctl.c:

Joachim Nilsson 077a7e82e0 Debian now boots to X!
finit.conf:
        Use this as /etc/finit.conf on a Debian 6.0 based system with X
        installed and sysklogd instead of rsyslogd.  Works.

services:
        Alternative method for extending the finit boot procedure. Simply
        place this script file in an /etc/finit.d/ directory.  The script
        uses the standard run-parts tool to chain load other start scripts.

helpers.c:
        o New functions:
          - run(): home grown system() replacement
          - run_interactive(): display progress and status when called

        o Bugfix start_process(), make sure to use same signal setup for
          children as in run() and run_interactive(). Also, use execvp()
          instead of execv() to allow searching $PATH for executables.

finit.h:
        o Move signal specific code to new signal.h.
        o Bypass verbosity setting to let echo() always print to screen.

finit.c:
        o Make run_parts() the default, remove external deps, it works.

        o Use run() and run_interactive() to speed up execution further
          on embedded systems where forking is expensive.

        o Kernel cmdline "quiet" should not close STDIO since this makes
          it impossible to run some daemons and start scripts.  Instead,
          we let "quiet" toggle the finit verbosity setting.

        o Remove kernel cmdline "--verbose" (Upstart compat), to be used
          to enable verbose finit when kernel should be quiet.

        o Setup kernel specific settings in /etc/sysctl.conf

        o Fix D-Bus startup problems. Probably what caused X from not
          working initially. Silly rabbit.

        o Use system() workaround to start X, cannot get it to start
          at all using run() or run_interactive() at the moment.

signal.h:
        New file, header file for signal.c.  Was about time.

signal.c:
        Remove blocking of SIGCHLD from sig_setup(), instead we setup
        SIGCHLD early in sig_init() to handle fork() in run() & C:o.

Joachim Nilsson d21dc2b477 Westermo service starter and supervisor, inspired by daemontools
finit.c:
        o New service and shell_service stanzas for finit.conf
        o Run service_startup() before /etc/finit.d/ hooks
        o Run service_monitor() at end of startup

helpers.c:
        o Several new functions:
          - print_desc() displays a service starting up
          - print_result() shows if service started OK or not
          - start_process() is used by the services framework

svc.c:
        Generic API for managing svc_t structures

ipc.o:
        TIPC based framework for communicating with the service monitor.
        E.g., to relay (re)configuration signals from a Web/CLI
        front-end via finit to one or many setup daemons, and back.

services.c:
        Service monitor framework

Joachim Nilsson c0356b5c7a Massive cleanup to be able to boot Debian 6.0
Update license and copyright information details in all files.
Much cleanup by moving hard coded strings/data to #defines and using more
common default values for each such #define.

finit.c:
        o Make sdown[], startx[] allocated strings by default NULL
        o This fixes the issues where the shutdown handler segfaulted
        o Add ability to handle NULL input to build_cmd() by allocating space
        o Ignore kernel cmdline "quiet" if in debug mode
        o Add support for "network" stanza in finit.conf
        o Mount -n to skip removing /etc/mtab
        o Call swapon to enable swap if enabled in /etc/fstab
        o Cleanup /tmp, /var/run and /var/lock
        o Move sig_setup() *after* mount, sig_init() otoh runs early
        o Start initctl monitor before forking off startx/getty process
        o The startx process is now the console process. Only a getty is
          started when in debug mode. Otherwise only X is started if it
          is properly setup in /etc/finit.conf
        o NOTE: Currently X evdev does not work!
        o Support for /usr/sbin/services.sh has been replaced with finit
          now instead supporting builtin run-parts for /etc/finit.d/

helpers.c:
        o Bug fixes in run_parts() and also added chdir(oldpwd) at bottom.
        o New functions:
          - getuser() similar to getgroup()
          - cls() clear screen, only runs when not in debug mode
          - set_procname() used to set name "console" on console process
          - set_hostname() encapsulates /etc/hostname and sethostname()

signal.c:
        o Split sig_setup() in two: sig_init() and sig_setup()
          The former to be called as soon as possible, while latter is
          supposed to run when the base filesystem is properly up.
        o Remove hard coded distribution specific progress bar write()
        o Add debug messages to do_shutdown()
        o Remove any lingering sync files in sig_setup()

initctl.c:
        o Add debug messages and a new default: case to catch stray runlevels
