[Buildroot] [PATCH v2 0/3] bump smcroute and add start script

[Joachim Wiberg]

Hi everyone!

This is the third version of the patch to update SMCRoute to the latest
version.  Previous versions were audited by Yegor and Thomas, thank you
for that!  There is a fresh bug fix release upstream and this patch set
has been updated to reflect that.

Also, there is now a SysV start script included, installed when a SysV
init is used.  The upstream systemd unit file was already instaled when
systemd is used.  Both of them support an optional /etc/default/smcroute
environment file that is sourced before starting smcrouted, for site
local cmdline options.

Basic tests pass:

    $ ./utils/check-package package/smcroute/*
    56 lines processed
    0 warnings generated
    $ ./utils/test-pkg -c smcroute.config -p smcroute

    6 builds, 1 skipped, 0 build failed, 0 legal-info failed

To verify the integration, manual testing from a clean master branch,
has been performed in Qemu (Aarch64) using with both BusyBox init and
systemd.

Best regards

[Buildroot] [PATCH v2 1/3] package/smcroute: bump version to v2.5.2

[Joachim Wiberg]

 - Upstream has changed to tar.gz
 - Drop _SOURCE, fixes check-package warning
 - setpgrp not used anymore, no need to override configure cache
 - Makefile no longer uses CC?=, drop comment
 - Enable MRDISC build option, must be activated per phyint in
   smcroute.conf, so safe to enable as a default build option

[Buildroot] [PATCH v2 2/3] package/smcroute: add sysv init script

[Joachim Wiberg]

Same start order as mrouted, start after networking is up.

Custom command line options, like startup delay, or disable multicast
routing by default, can be added to the optional /etc/default/smcroute
env. file.

 This is not how we usually write our start scripts, but I like it!

 Can't you pass the -x here as well (which makes sure that you actually kill the
intended daemon in stop() and not some other random process that happens to have
the same PID)?

 Anyway, I applied as is.

Thank you, I wasn't sure it would pass inspection :)

Huh, from the usage text of start-stop-daemon it wasn't clear to me if
-x was reserved only for starting.  Thanks for alerting me to this!

>  Anyway, I applied as is.

Thanks, I'll push another bump later today, for the v2.5.3 release,
which will include a fix for -x as well.

Cheers

[Buildroot] [PATCH v2 3/3] package/smcroute: prune old smcroute compat script

[Joachim Wiberg]

Long ago, before SMCRoute had yet become a proper daemon and standalone
control tool, it was both.  After the metamorphosis commands and options
had changed, a compat script was added to provide a smooth transition.

The compat script is still shipped in the tarball, and installed, but
only Debian still relies on it, so we prune it here to keep confusion
to a minimum, hopefully.
