[Bug 1012102] [NEW] Check all configuration files for except-interface lo

[Thomas Hood]

Public bug reported:

In the start_resolvconf() function the initscript correctly refrains
from registering the loopback IP address with resolvconf if "lo" is in
DNSMASQ_EXCEPT.


    start_resolvconf()
    {
    # If interface "lo" is explicitly disabled in /etc/default/dnsmasq
    # Then dnsmasq won't be providing local DNS, so don't add it to
    # the resolvconf server set.
            for interface in $DNSMASQ_EXCEPT
            do
                    [ $interface = lo ] && return
            done


With the latest dnsmasq, however, options can also be added by means of configuration file parts in /etc/dnsmasq.d/.  This mechanism has already been used to exclude virbr interfaces (see #928524) and may be used in the future to exclude the lo interface (see #959037).  In anticipation of such uses the initscript should check configuration files for "except-interface=lo" and in its presence refrain from registering the loopback IP address with resolvconf.
