Hi,

after recent update to 2.86 on Debian sid I'm seeing
failures in name resolution. I think the issue is that
my Wifi connection is currently flaky (another problem
to solve...) and the DNS reply gets lost. After that
dnsmasq reports REFUSED, e.g.:

Sep 20 21:06:38 dnsmasq[18805]: 55 127.0.0.1/33372 query[A] m.heise.de from 127.0.0.1
Sep 20 21:06:38 dnsmasq[18805]: 55 127.0.0.1/33372 forwarded m.heise.de to 192.168.178.1
Sep 20 21:06:38 dnsmasq[18805]: 56 127.0.0.1/33372 query[AAAA] m.heise.de from 127.0.0.1
Sep 20 21:06:38 dnsmasq[18805]: 56 127.0.0.1/33372 forwarded m.heise.de to 192.168.178.1
Sep 20 21:06:43 dnsmasq[18805]: 57 127.0.0.1/33372 query[A] m.heise.de from 127.0.0.1
Sep 20 21:06:43 dnsmasq[18805]: 57 127.0.0.1/33372 config error is REFUSED
Sep 20 21:06:43 dnsmasq[18805]: 58 127.0.0.1/33372 query[AAAA] m.heise.de from 127.0.0.1
Sep 20 21:06:43 dnsmasq[18805]: 58 127.0.0.1/33372 config error is REFUSED

Some time later:

Sep 20 21:13:51 dnsmasq[18805]: 171 127.0.0.1/45279 query[A] m.heise.de from 127.0.0.1
Sep 20 21:13:51 dnsmasq[18805]: 171 127.0.0.1/45279 forwarded m.heise.de to 192.168.178.1
Sep 20 21:13:51 dnsmasq[18805]: 172 127.0.0.1/45279 query[AAAA] m.heise.de from 127.0.0.1
Sep 20 21:13:51 dnsmasq[18805]: 172 127.0.0.1/45279 forwarded m.heise.de to 192.168.178.1
Sep 20 21:13:51 dnsmasq[18805]: 171 127.0.0.1/45279 reply m.heise.de is 193.99.144.88
Sep 20 21:13:51 dnsmasq[18805]: 172 127.0.0.1/45279 reply m.heise.de is 2a02:2e0:3fe:1001:7777:772e:0:88


Shouldn't dnsmasq retry the query?


Best Regards,
Johannes
