Subject: unbound: fix local_subnet for IPv6 addresses that contain a port
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=33581043d28ad63a2b511db0faf66d7777e608fb;p=feed%2Fpackages.git

unbound: fix local_subnet for IPv6 addresses that contain a port

This prevents a forwarding server named like ::1@5453 from being added
to unbound.conf as a forward-host instead of the correct forward-addr.
forward-host requires the name to be resolved, which is impossible in
the absence of another nameserver. Thus, forwarding-only configurations
referencing only the IPv6 loopback address with a port number were
broken.
