Bird4 not starting after reboot

[pwgen]

Hi,

I have noticed that this behaviour changed. A few months ago we’ve implemented dynamic routing with bird4 and this problem didn’t exist, I was able to start/stop processes correctly.
Right now, after one of last updates, we have broken init script for bird4 - which in end effect also causes service to be not started after reboot:
# BIRD not running:
root@turris-bnd:~# ps ax | grep bird
12789 pts/0 S+ 0:00 grep bird

# Starting with init script fails silently:
root@turris-bnd:~# /etc/init.d/bird4 start
root@turris-bnd:~# ps ax | grep bird
12803 pts/0    S+     0:00 grep bird

# Starting process manually works fine
root@turris-bnd:~# bird4 -c /etc/bird4.conf
root@turris-bnd:~# ps ax | grep bird
12816 ?        Ss     0:00 bird4 -c /etc/bird4.conf
12818 pts/0    S+     0:00 grep bird

What should I do in order to restore functionality of the init script?

Hello,

Would you please share your Turris OS version and your model of the router?

[pwgen]

Hardware: Turris Omnia 2 GB Wi-Fi
Turris OS: 3.11.10
Kernel: 4.4.196-a890a5a94ebb621f8f1720c24d12fef1-0
Package version: bird4 - 1.6.8-1

When I look on release notes, I see that bird was updated in version 3.11.8 (released on 14th October 2019) and while I can’t prove it right now, it seems like a time match - as far as I remember, it was in late October / early November when init script was broken.

Hello Marek,
how do you manage your bird setup? Do you use UCI for management?

Would you please share the result of
opkg list-installed | grep bird

Thank you.

Hi, I have installed and configured bird via CLI (opkg install and manually created /etc/bird4.conf).

# opkg list-installed | grep bird
bird4 - 1.6.8-1
bird4-uci - 0.2
birdc4 - 1.6.8-1
birdcl4 - 1.6.8-1
luci-app-bird4 - 0.2

Hi,
as you manage the bird4 by direct editing of /etc/bird4.conf, can you try to uninstall the bird4-uci and luci-app-bird4 packages?

The uninstallation should restore the original init script shipped with bird4 package.
Let me know the result.

Regards, Jan

Hello Jan,

I uninstalled those packages - and also tried uninstalling all packages and installing then just bird4+birdc4. Still same result, calling init script does not start the service. This made me think that something can be broken on my side. I figured out that I’ve started the service once as root and this created logfiles - starting with init script drops user to bird, who couldn’t write to the log file. Thanks for your suggestions, problems is solved.
I might suggest that we could maybe not “lose” the error message from bird4 (or any other service handled by rc.common) and display it when service fails to start:

# start-stop-daemon -S -p /var/run/bird4.pid -x /usr/sbin/bird4 -- -d -u bird -g bird -c /etc/bird4.conf -P /var/run/bird4.pid
bird: /etc/bird4.conf:1:5 Unable to open log file `/srv/bird4.log': Permission denied

but that’s another story i guess

Best regards,
Marek
