Description

Tested on 22.05.a.20220417.0600.

Tested with the feature from:
https://redmine.pfsense.org/issues/13057

The interval is added correctly:

root 62793 0.0 0.3 12140 2784 - Is 18:44 0:00.01 |-- /usr/local/sbin/filterdns -p /var/run/filterdns-ipsec.pid -i 10 -c /var/etc/ipsec/filterdns-ipsec.hosts -d 1

However, the actual resolve interval seems to be done at twice the value in the config (tested with 10 and 15 second intervals - reboot after each change):

The code inexplicably added the interval mod 30 to the interval, I've fixed this as of https://github.com/pfsense/FreeBSD-ports/commit/d522e1f53e53bf70438e02ac1d00b1f1feb733fa as part of fixes for #9296

Tested against:

2.7.0-DEVELOPMENT (amd64)
built on Fri Oct 28 06:06:25 UTC 2022
FreeBSD 14.0-CURRENT

the interval of 10s was added correctly:

root    73776   0.0  0.2  21772  3668  -  Is   18:01      0:00.02 /usr/local/sbin/filterdns -p /var/run/filterdns-ipsec.pid -i 10 -c /var/etc/ipsec/filterdns-ipsec.hosts -d 1

However, the resolver logs with verbosity level 3 set didn't show any queries for the defined hostname in Phase 1.

Here are the only relevant logs for that hostname in the resolver logs:
