Package: bind9
Version: 1:9.9.5.dfsg-4
Severity: important
Tags: patch
Currently, the following scripts are installed by the bind9 package:
/etc/ppp/ip-up.d/bind9
/etc/ppp/ip-down.d/bind9
/etc/network/if-up.d/bind9
/etc/network/if-down.d/bind9
These scripts contain the following call:
rndc reconfig >/dev/null 2>&1 || true
I had an issue on my system that made the named daemon freeze in such
a way that any rndc command would hang forever. Since rndc is called as
part of network interface up/down scripts, it made these scripts hang as
well. As a result, my machine lost its network connection.
Network interface up/down scripts should not have a critical dependency
on some non-critical part of the system (bind9) behaving correctly.
Otherwise it makes the network subsystem exceedingly brittle.
To fix the issue, I suggest replacing the line above with the following
so that the network subsystem will never wait on rndc:
rndc reconfig >/dev/null 2>&1 &
