[Dnsmasq-discuss] Incorrect SERVFAIL on dnssec and rivcoe...
Petr Menšík via Dnsmasq-discuss · 2025-12-13 · via dnsmasq-discuss
There is created pihole issue for in fact dnsmasq problem:

https://github.com/pi-hole/FTL/issues/2737

dnsmasq fails where both unbound and bind9 pass the verification as insecure. The problem is that domain has incorrect owner name in RRSIG: cloudflare.net.

I will try to create patch sometime around christmas, but just wanted to make it known. Somebody might be faster. Verified it happens on last released dnsmasq. Have not tried last git, but expect that is affected as well.

it is okay by other implementations:

delv rivcoed.org.

unbound-host -rvDt A rivcoed.org.

I think because rivcoed.org. DS record is not present anyway, signature does not need to be checked in this case. dnsmasq fails too early.

Cheers,
Petr
