Bug#676798: munin-node: Munin-node does not allow IPv6 localhost connections

Package: munin-node
Version: 2.0.0-1
Severity: normal
Tags: upstream ipv6

Hey Holger,

the default munin-node configuration doesn't allow localhost IPv6
connections.

Adding a

allow ^::1$

fixes this.


This would also be a good opportunity to get rid of the travesty that is
the regex netblock matching and fix #611145 in the process but apparently
there's a bug in munin/Net::CIDR since

cidr_allow ::1/128
cidr_allow 127.0.0.1/32

doesn't allow v6 localhost connections either.


All the best,
Michael
