Subject: dnsmasq: Reloading dnsmasq with systctl results in stop

Date: Wed, 09 Jul 2014 21:03:14 +0400

Package: dnsmasq
Version: 2.71-1
Severity: important

Dear Maintainer, when reloading dnsmasq with changed configuration, daemon stops.
Config is valid, daemon can be started normally after that.

Log of the daemon after systemctl reload action:

July 09 20:53:20 host systemd[1]: Reloading A lightweight DHCP and caching DNS server.
July 09 20:53:20 host dnsmasq[1529]: read /etc/dnsmasq-home.hosts - 2 addresses
July 09 20:53:20 host dnsmasq[1529]: exiting on receipt of SIGTERM
July 09 20:53:20 host systemd[1]: Reloaded A lightweight DHCP and caching DNS server.

Somewhere along the way dnsmasq recieves SIGTERM
It happens only if configuration is changed. Reloading daemon with unchagned config does not stop it.

I tried "making a trivial change to /etc/dnsmasq.conf" as a way to
change the configuration, but I can't reproduce this problem. Could you
give a bit more detail on how you're changing the configuration.

Note that sending SIGHUP to dnsmasq (which is what systemctl reload
does) Will NOT make it re-read it's configuration, except for a small
number of specific items. To use a new configuration, you need to
restart dnsmasq, via systemctl restart.

Cheers,

Simon.

Hm... usually changing additional hosts file was enough to trigger this bug. But now I can not reproduce it either.
I've rechecked it on both my home servers and now the bug is gone. Tried adding upstream server in config file and host in addn-hosts file. Reload did not trigger daemon stop this time.
Maybe it has something to do with recent upgrades. I had this bug o two machines before.

My test was on an up-to-date sid system. Since there have been no
changes to dnsmasq, I guess it was a bug in systemd which is now fixed.
I can't see anything obvious in the the changelog though.

Just wanted to recheck just in case, and here it goes again!

It seems nothing is relevant except isc-dhcp packages.
I will try to just send HUP directly after some time to see what happens if I exclude systemd from the reload process.

Sending HUP to main process does not result in stop.
Doing systemctl reload sometimes does. This time it was after systemd was upgraded from 204-14 to 208-6. I will recheck after some time.

I couldn't reproduce this while testing my proposed patch for
<https://bugs.debian.org/776530> on a current jessie virtual machine
(systemd 215-10). Do you still see this bug?
