I just did a simple test that looks analogous to what you're doing, and it all worked as expected.


dnsmasq: DNSSEC validation enabled
dnsmasq: configured with trust anchor for <root> keytag 20326
dnsmasq: using nameserver 127.0.0.1#10002 for domain internal
dnsmasq: using nameserver 8.8.8.8#53
dnsmasq: read /etc/hosts - 10 names
dnsmasq: query[A] simon.internal from ::1
dnsmasq: forwarded simon.internal to 127.0.0.1#10002
dnsmasq: dnssec-query[DS] internal to 8.8.8.8
dnsmasq: dnssec-query[DNSKEY] . to 8.8.8.8
dnsmasq: reply . is DNSKEY keytag 21831, algo 8
dnsmasq: reply . is DNSKEY keytag 38696, algo 8
dnsmasq: reply . is DNSKEY keytag 20326, algo 8
dnsmasq: Negative DS reply without NS record received for internal, assuming non-DNSSEC domain-specific server.
dnsmasq: reply internal is no DS
dnsmasq: validation result is INSECURE
dnsmasq: reply simon.internal is 1.2.3.4

So there's something that's in your setup but not mine that I didn't think of.

As a start, please could you enable log-queries and run the test again, then post the resulting log.


Cheers,

Simon.

Dears,

i use a customs dnsmasq confirguration in which dnsmasq uses my local DNS 
Server for unqualified hostnames and hostnames with custom domain dw.internal

Configuration looks like this:


# Add other name servers here, with domain specs if they are for
# non-public domains.
servers-file=/var/run/NetworkManager/local-net-dns-servers.conf


/var/run/NetworkManager/local-net-dns-servers.conf

server=/dw.internal/10.24.64.3@eth0
server=//10.24.64.3@eth0

i have DNSSEC Validation enabled, an now when querying a local hostname:

dig router1.dw.internal

dnsmasq tries to validate the response even if this local zone is not 
signed.validation router1.dw.internal is ABANDONED

i fixed this by including trust-anchor=internal in the global dnsmasq.conf
But maybe we can AUTOMATICALLY exclude any custom non-public domain from 
dsnssec validation?
If not possible , does the logic allow including the trust-anchor statement in 
the servers-file ?


Prior v2.92  Validation for internal domain just went fine
Expecting any advise--
