[3.1][] - 2017-12-xx
|
||||
[3.2][UNRELEASED] - 2018-10-xx
|
||||
------------------------------
|
||||
|
||||
Bug fix release.
|
||||
|
||||
### Changes
|
||||
* Add support for `--disable-docs` and `--disable-contrib` to speed up
|
||||
builds and work around issue with massively parallel builds
|
||||
* Add `-b`, batch mode, for non-interactive use to `initctl`
|
||||
* Prefer udev to handle `/dev/` if mdev is also available
|
||||
* Redirect dbus daemon output to syslog
|
||||
* Set `$SHELL`, like `$PATH`, to a sane default value, needed by BusyBox
|
||||
* Finit no longer automatically reloads its `*.conf` files after running
|
||||
`/etc/rc.local` or run-parts. Use `initctl reload` instead.
|
||||
* `initctl` without an argument or option now defaults to list services
|
||||
* Converted built-in watchdog daemon to standalone mini watchdogd
|
||||
* Improved watchdog hand-over, now based on `svc_t` and not PID
|
||||
* Extended bootstrap, runlevel S, timeout: 10 --> 120 sec. before services
|
||||
not allowed in the runtime runlevel are unconditionally stopped
|
||||
* Removed `HOOK_SVC_START` and `HOOK_SVC_LOST`, caused more problems
|
||||
than they were worth. Users are encouraged to use accounting instead
|
||||
* Skip displaying "Restarting ..." progress for bootstrap processes
|
||||
* Added a simple work queue mechanism to queue up work at boot + runtime
|
||||
- Postpone deletion of `svc_t` until any `SIGKILL` timer has elapsed
|
||||
- As long as a stepped service changes state we queue another step all
|
||||
event, because services may depend on each other
|
||||
* Require new libuEv API: `uev_init1()` to reduce event cache so that
|
||||
the kernel can invalidate deleted events before enqueing to userspace
|
||||
|
||||
### Fixes
|
||||
|
||||
* Fix #96: Start udevd as a proper service
|
||||
* Ensure we track run commands as well as task/service, once per runlevel
|
||||
* Fix #98: FTBFS with `--disable-inetd`
|
||||
* Make sure to unblock UDP inetd services when connection terminates.
|
||||
Regression introduced in v3.1
|
||||
* Ensure run/tasks also go to stopping state on exit, like services,
|
||||
otherwise it is unnecessarily hard to restart them
|
||||
* Fix #99: Do not try to `SIGKILL` inetd services, they are not backed
|
||||
by a PID. This caused a use after free issue crashing finit. Found
|
||||
and fixed by Tobias Waldekranz, Westermo
|
||||
* Fix missing OS/Finit title bug, adds leading newline before banner
|
||||
* Remove "Failed connecting to watchdog ..." error message on systems
|
||||
that do not have a watchdog
|
||||
* Fix #100: Early condition handling may not work if `/var/run` does
|
||||
not yet exist (symlink to `/run`). Added compat layer for access
|
||||
* Fix #103: Register multiple getty if `@console` resolves to >1 TTY
|
||||
* Fix #105: Only remove /etc/nologin when moving from runlevel 0, 1, 6
|
||||
* Fix #106: Don't mark inetd connections for deletion at .conf reload.
|
||||
Fixed by Jonas Johansson, Westermo
|
||||
* Fix #107: Stop spawned inetd conncections when stopping inetd service.
|
||||
Fixed by Jonas Johansson, Westermo
|
||||
* Fix #111: Only restart inetd services when necessary. E.g., if the
|
||||
listening interface is changed. Only stop established connections
|
||||
which are no longer allowed, i.e. do not touch already allowed
|
||||
established connections. Fixed by Jonas Johansson, Westermo
|
||||
* Fix: update inetd service args on config change. Found and fixed by
|
||||
Petrus Hellgren, Westermo
|
||||
* Fix `initctl [start | restart]`, should behave the same for services
|
||||
that have crashed. Found by Mattias Walström, Westermo
|
||||
* Wait for bootstrap phase to complete before cleaning out any bootstrap
|
||||
processes that have stopped, they may be restarted again
|
||||
* Reassert condition when an unmodified run/task/service goes from
|
||||
WAITING back to RUNNING again after a reconfiguration event.
|
||||
Found and fixed by Jonas Johansson, Westermo
|
||||
* Remove service condition when service is deleted

Finit v3.1 require libuEv v2.1.0, or later, and libite v2.0.1, or later.

Improvements to `netlink.so` plugin, per-service `rlimit` support,
|
||||
improved integration with `watchdogd`, auto-detect TTY console. Much
|
||||
improved debug, rescue and logging support. Also, many fixes to both
|
||||
big and small issues, most notably in the condition handling, which no

longer is sensitive to time skips.

This version requires at least libuEv v2.1.0 and libite v2.0.1

### Changes
|
||||
|
||||
* Support for more kernel command line settings:
|
||||
- splash, enable boot progress
|
||||
- debug, like `--debug` but also enable kernel debug
|
||||
- single, single user mode (no network)
|
||||
- rescue, new rescue mode
|
||||
* Support for `IFF_RUNNING` to netlink plugin => `net/IFNAME/running`
|
||||
* Support for restarting `initctl` API socket on `SIGHUP`
|
||||
* Greatly updated `initctl status <JOB|NAME>` command
|
||||
* Support for `rlimit` per service/run/task/inetd/tty, issue #45
|
||||
* Support for setting `hard` and `soft` rlimit for a resource at once
|
||||
* Support for auto-detecting serial console using Linux SysFS, the new
|
||||
`tty @console` eliminates the need to keep track of different console
|
||||
devices across embedded platforms: `/dev/ttyS0`, `/dev/ttyAMA0`, etc.
|
||||
* Add TTY `nologin` option. Bypasses login and skips immediately to a
|
||||
root shell. Useful during board bringup, in developer builds, etc.
|
||||
* Support for calling run/tasks on Finit internal HOOK points, issue #18
|
||||

General

-------
|
||||
Near Future
|
||||
-----------
|
||||
|
||||
* Add support for `rescue` on the kernel command line, start rescue mode
|
||||
if enabled with `configure` script. Could mean skip `/etc/finit.conf`
|
||||
et al and jump straight to a single getty login on console.
|
||||
* Add support for timed shutdown in Finit, including cancelled shutdown.
|
||||
* SysV init and systemd use SIGUSR1 to restart their FIFO/D-Bus. Add
|
||||
API restart to SIGHUP callback for the same functionality in Finit.
|
||||
* Merge UDP redirect service uredir as an UDP inetd variant
|
||||
* Add `finit.conf` support for UPS notification (SIGPWR) to start a task
|
||||
using, e.g. <sys/power/{ok,fail,low}> conditions. More info in sig.c
|
||||
* Add `finit.conf` support for ctrl-alt-delete (SIGINT) and kbrequest,
|
||||
i.e. KeyboardSignal, (SIGWINCH) behavior. Using conditions to a task,
|
||||
e.g, <sys/key/ctrlaltdel> and <sys/key/signal> like SIGPWR handling.
|
||||
* Add `IFF_RUNNING` support to netlink plugin along `IFF_UP`
|
||||
* Implement `initctl stop|start|restart|reload|status <SVC>` and
|
||||
`service <SVC> stop|start|restart|reload|status` on top
|
||||
* Cron/At support, see below
|
||||
* Write man pages for finit and `finit.conf`, steal from the excellent
|
||||
`pimd` man pages ...
|
||||
* Add simple, *very* simple, `finit-simple.conf` example. To illustrate
|
||||
how close Finit3 still is to the original easy-to-use Finit0 :)
|
||||

General

-------
|

|
||||
* Add support for timed shutdown in Finit, including cancelled shutdown,
|
||||
possibly using an at-job, see [crond section](#Crond) below
|
||||
* Add support for JSON output, or similar, from `initctl show`, e.g.
|
||||
`initctl show --json`
|
||||
* Improve `initctl show SVC` output. Add service uptime, last ten SVC
|
||||
logs/history (historian), etc. Similar to `systemctl show SVC`
|
||||
* [Solaris SMF][] (Service Management Facility) has some interesting

||||
features that may be well worth looking into adopting:

Tips & Tricks with the kernel cmdline
|
||||
=====================================
|
||||
|
||||
This document summarizes the different boot parameters that can be
|
||||
passed on the Linux kernel command line. Not just limited to Finit.
|
||||
|
||||
* `debug`, or `--debug`
|
||||
Enable debug mode. The former syntax also enable kernel debug, and
|
||||
the latter only in Finit. Debug messages are printed to the console
|
||||
until a syslog daemon has been started.
|
||||
|
||||
* `init=/bin/sh`
|
||||
Bypass system default init and tell kernel to start a shell. Note,
|
||||
this shell is very limited and does not support signals and has no
|
||||
job control. Recommend using, and modifying, `rescue` mode instead.
|
||||
|
||||
* `panic=SEC`
|
||||
By default the kernel does not reboot after a kernel panic. This
|
||||
setting will cause a kernel reboot after SEC seconds.
|
||||
|
||||
* `quiet`
|
||||
Suppress kernel logging to console, except for warnings and errors.
|
||||
|
||||
* `rescue`
|
||||
Start Finit rescue mode; no network, no `fsck` of file systems in
|
||||
`/etc/fstab`, no `/etc/rc.local`, no `runparts`. The configuration
|
||||
is read from `/etc/rescue.conf`, can be modified by the operator.
|
||||
|
||||
* `single`, or `S`
|
||||
Single user mode, runlevel 1, in Finit. Useful to debug problems with
|
||||
the regular runlevel. All services and TTYs in `[1]` will be started,
|
||||
so a `tty [1] @console nologin` configuration presents you with a
|
||||
root console without login.
|
||||
|
||||
* `splash`
|
||||
Display Finit splash screen with progress at bootstrap and shutdown.

Service Wrapper Scripts
|

-----------------------
|
||||
|
||||
If your service requires to run additional commands, executed before the
|
||||
service is actually started, like the systemd `ExecStartPre`, you can
|
||||
use a wrapper shell script to start your service.
|
||||
|
||||
The Finit service `.conf` file can be put into `/etc/finit.d/available`,
|
||||
so you can control the service using `initctl`. Then use the path to
|
||||
the wrapper script in the Finit `.conf` service stanza. The following
|
||||
example employs a wrapper script in `/etc/start.d`.
|
||||
|
||||
**Example:**
|
||||
|
||||
* `/etc/finit.d/available/program.conf`:
|
||||
```conf
|
||||
service [235] <!> /etc/start.d/program -- Example Program
|
||||
```
|
||||
|
||||
* `/etc/start.d/program:`

#!/bin/sh

# Prepare the command line options

||||
OPTIONS="-u $(cat /etc/username)"
|
||||
|
||||
# Execute the program
|
||||
exec /usr/bin/program $OPTIONS
|
||||
```
|
||||
|
||||
**Note:**, that the example sets `<!>` to denote that it doesn't support
|
||||
`SIGHUP`. That way Finit will stop/start such the service instead of

||||
sending SIGHUP at restart/reload.

application Finit provides a workaround. A `pid` keyword can be set

to have Finit automatically create (when starting) and later remove

(when stopping) the PID file. The file is created in the `/var/run`

modified with an optional argument:

For example, by adding `pid:/run/foo.pid` to the service `bar` that

be used by the Finit condition subsystem. So another service/run/task

If a service `bar` *does* maintain a PID file, but using `foo.pid`, we

This file used to be the only way to set up and boot a Finit system.

Today it is mainly used for pre-runtime settings like system hostname,
