BUG: As feared… New Unbound version 1.4.21_1, new bugs for free ...
-
Hi,
is it please possible to check the update on a VM that the package works also on 2.0.3 (and I guess then also on other 2.0.x versions) ?
When I updated our slave firewall after several weeks of thinking if I should try it (because of time) unbound doesn't started after updated as "expected".
-
1st check was showing that unbound was deactivated after upgrading… ?
=> check "Enable unbound" -
2nd found problem was then that saving config was not possible:
=> Fatal error: Call to undefined function get_interface_ipv6() in /usr/local/pkg/unbound.inc on line 838
On 2 places there is an ipv6 function without proving if function exists.
short patch form to show changes:

Setting "num-threads:2"So here is the temporary fix for 2.0.x - I guess on 2.1 it would work without it… :
