Joachim Wiberg 263aec292a Support for disabling invocation of rescue mode from kernel cmdline
The rescue mode that can be invoked from the kernel command line is
potentially unsafe.  Many systems lock the root user account, or use
another account for managing, e.g. 'admin'.  The sulogin program(s)
would on such systems give the user a root prompt.

In #357 we added support for setting a custom sulogin user, but for some
systems that is not enough.  On many embedded systems the /etc/passwd
and shadow files are populated at bootstrap and at the time rescue mode
runs, these files will be unpopulated.

The only, truly safe, approach on such systems is to disable rescue mode
completely.  Otherwise intricate Finit plugins have to be used that run
before rescue mode is started -- increasing the complexity of the system
as a whole.

Joachim Wiberg 6e7a2fb6d5 Fix #357: allow sulogin with user different from 'root'
In issue #357 there's a proposal for optionally allowing /bin/login, but
after intense discussions we've agreed that would be opening up for all
sorts of potential (security) issues.

it's better to keep things as-is but with the added twist of supporting
a custom user at configure time, e.g., 'admin'.

Joachim Wiberg ddedcf77e8 Follow-up to 4701ede: reschedule bootstrap check while not done
Non-trivial systems, like Infix[1], require more than one lap around the
track to warm up.  This is a follow-up to issue #362, commit 4701ede, in
fixing an obvious oversight in the new sm_check_bootstrap() work.  While
there are still outstanding bootstrap tasks or services that have not
yet started, we must reschedule the worker.

Drop complete() logic, waiting for run tasks to finish, from the
service_start() funciton to the general service_monitor().  This
refactor frees up the main loop and allows us to answer any API
calls from initctl even from the run task itself.

Joachim Wiberg f2507d9fd7 runparts: fix arg handling and skip backup files
For some specialized forms of runparts, e.g., start-stop scripts in SysV
init replacements, there is a need to append an argument.  Typically
this is 'start' or 'stop'.

This functionality has been broken for quite some time, meaning we
should consider it being unused by current users of Finit.

Joachim Wiberg a58002588e Refactor initial startup, run runparts and rc.local in background
The code refactored in this commit has long been an eyesore.  The
hand-over, from the sequential main() function, to the event loop
was clumsy at best and was very difficult to debug.

Instead of using a series of workers we now delegate everything to
the big state machine by introducing a new SM_BOOTSRTAP_WAIT_STATE.

Both the runparts and rc.local scripts now run in the background, no
longer blocking the event loop from responding to initctl calls.  To
ensure they run at the same point in time two things have been done:

 1. A new <int/bootstrap> condition has been added which triggers
    runparts, which now is a regular task created by conf_init()
 2. /etc/rc.local is started from SM_RUNLEVEL_WAIT_STATE when we
    transition from runlevel S to any other runlevel.

Fixes #356

The execvp() call always fails with -1, so only logging exit code when
collecting the PID is not enough.  When debugging the user needs to see
the errno from execvp(), e.g., "No such file or directory", when the
command was missing the absolute path to the executable.

Joachim Wiberg 6f0d448765 Fix #227: delayed service_kill() may stall shutdown/reboot
This turns out to be the root-cause of #227.  Finit is waiting forever
for proceeses to stop at shutdown/reboot, while a subreaper has already
collected the PID, or Finit for some reason did not collect the PID.

When the process timeout calls service_kill() we now check if the kernel
actually knows of this process or not.  If it's already been collected,
we can notify Finit of this by calling service_monitor() to clean up the
'svc' and in turn call sm_step() to finalize the state transition.

These changes add a new svc_block_t type: SVC_BLOCK_CONFLICT so a user
can more clearly see why a run/task/service has not been started by
Finit.  The reason for the block is by default logged, which can be
escaped by using the `nowarn` flag.

Also, when the conflict is resolved, allow the service to start.

Joachim Wiberg 712f68f9da Fix #355: regression stopping a process and its group
In 91a9c83 a regression was introduced that affects the way Finit stops
a supervised process and its process group.

Instead of sending SIGTERM to the process, delegating the responsibility
to that process to inform any children it may have, Finit as of 91a9c83
sends SIGTERM to the entire process group.  For SIGKILL this is fine,
SIGKILL only runs as cleanup and as a last ditch effort if the process
doesn't respond to SIGTERM.

This regression, introduced in v3.2, directly affects services like
avahi-autoipd that have forked off children that it needs to tell to
exit cleanly before it returns. With the patch in question these
children are never allowed to complete, which in turn causes lingering
169.254 link-local addresses on interfaces.

[4.5][] - 2023-09-14
--------------------
### Changes
- Refactor `runparts` and `/etc/rc.local` to no longer block the main
loop, allowing these scripts to call `initctl` to interact with Finit.
Still in a limited way due to them being used at bootstrap, issue #356
- Refactor the `run` stanza to no longer block the main loop, issue #362
- Allow `sulogin` with a user different from `root`, issue #357
- Allow disabling invocation of rescue mode from kernel command line
- Add `initctl -f` to force-skip asking Finit for existing services
when creating new services during bootstrap, e.g. `/etc/rc.local`
- `initctl runlevel` now returns `N S` instead of `N 10` in bootstrap
- Improved logging on failure to `execvp()` a run/task/service, now
with `errno`, e.g., "No such file or directory" when the command
is missing from `$PATH`
- Add support for Bash completion to `initctl`, issue #360
- Handle absolute path to `initctl [enable|disable]`, not supported
- Update `finit.conf(5)` man page with the recommended directory
hierarchy in `/etc/finit.d/`
- The `runparts` code has been split into `/libexec/finit/runparts`
- Add SysV Init Compatibility section to documentation
### Fixes
- Fix #227: believed to have been fixed in [4.3][], the root cause was
actually that Finit was waiting for a process that was no longer in
the system. The fix is to ask the kernel on process-stop-timeout and
replay the lost PID so that Finit can continue with reboot/shutdown
- Fix #358: fix inotify events for `/etc/finit.conf`, improved log
messages and error handling
- Fix #361: cgroup move fail if run/task/services start as non-root.
Regression in the [4.4][] release cycle while adding support for the
pre:/post:/ready: scripts. Now the latter scripts also properly run
in their correct cgroup
- The `runparts` executor now skips backup files (`foo~`)
- The `runparts` stanza now properly appends ` start` to scripts that
start with `S[0-9]+`. This has been broken for a very long time.

SysV Init Compatibility
-----------------------
Finit comes with a few SysV Init compatibility features to ease the
transition from a serialized boot process.
### `runparts DIRECTORY`
For a directory with traditional start/stop scripts that should run, in
order, at bootstrap, Finit provides the `runparts` directive. It runs
in runlevel S, at the very end of it (before calling `/etc/rc.local`)
making it perfect for most scenarios.
For syntax details, see [Run-parts Scripts](#run-parts-scripts) above.
Here is an example take from a Debian installation:
runparts /etc/rc2.d
Files in these directories are usually named `SNNfoo` and `KNNfoo`,
which Finit knows about and automatically appends the correct argument:
/bin/sh -c /etc/rc2.d/S01openbsd-inetd start
or
/bin/sh -c /etc/rc0.d/K01openbsd-inetd stop
Files that do not match this pattern are started similarly but without
the extra command line argument.
### Start/Stop Scripts
For syntax details, see [SysV Init Scripts](#sysv-init-scripts), above.
Here follows an example taken from a Debian installation:
sysv [2345] <pid/syslogd> /etc/init.d/openbsd-inetd -- OpenBSD inet daemon
The init script header could be parsed to extract `Default-Start:` and
other parameters for the `sysv` command to Finit. There is currently no
way to detail a generic syslogd dependency in Finit, so `Should-Start:`
in the header must be mapped to the condition system in Finit using an
absolute reference, here we depend on the sysklogd project's syslogd.
### `/etc/rc.local`
One often requested feature, early on, was a way to run a site specific
script to set up, e.g., static routes or firewall rules. A user can add
a `task` or `run` command in the Finit configuration for this, but for
compatibility reasons the more widely know `/etc/rc.local` is used if
it exists, and is executable. It is called very late in the boot process
when the system has left runlevel S, stopped all old and started all new
services in the target runlevel (default 2).
> In Finit releases before v4.5 this script blocked Finit execution and
> made it as good as impossible to call `initctl` during that time.
### `init q`
When `/sbin/finit` is installed as `/sbin/init`, it is possible to use
`init q` to reload the configuration. This is the same as calling
`initctl reload`.

More comprehensive setups, however, require more careful planning.
The recommendation is per-package

This allows end users to enable and disable parts of the system
configuration at runtime. Finit tracks which tasks and services belong
to a given file, so that when the user calls
.Cm initctl reload
to activate the changes they have made, only the affected tasks and
services are stopped, started, or restarted. Hence, this approach is
useful for modern package-based Linux distributions.
