Package: dnsmasq Version: 2.20-1 Severity: normal
I just started using dnsmasq again after a couple of months and I find that the current version of dnsmasq does not re-read resolv.conf when it is updated. Sending SIGHUP to the process causes it to re-read /etc/hosts but not resolv.conf.
$ ps -lf -C dnsmasq F S UID PID PPID C PRI NI ADDR SZ WCHAN STIME TTY TIME CMD 5 S nobody 2773 1 0 76 0 - 437 - 08:55 ? 00:00:00 /usr/sbin/dnsmasq -r /var/run/dnsmasq/resolv.conf

Versions of packages dnsmasq depends on: ii libc6 2.3.2.ds1-20 GNU C Library: Shared libraries an ii netbase 4.20 Basic TCP/IP networking system
-- no debconf information
Just to get things straight: by default dnsmasq checks the mtime of resolv.conf and re-reads it when the mtime changes. In this mode it does _not_ re-read resolv.conf on a SIGHUP.
Setting the --no-poll flag or adding it to /etc/dnsmasq.conf changes the behaviour to more traditional re-read the file on SIGHUP mode.
I'm not clear which mode is in use here, but both seem to be working fine for me, so a more detailed check on the reason for the problem is going to be needed.
Cheers,
Simon.
