[Dnsmasq-discuss] No cache for CNAME records that point to the host's address

[Janos.Mattyasovszky at bmw.de]

Hi,

Happy new year at the very beginning!

I derived a patch against the git tag v2.72 for that particular commit and built my own 2.72 with the patch on top, and it works as we expected it:

First try with nothing cached:
Jan  2 10:35:32 dnsmasq[8021]: query[A] itavm0002test.muc from 127.0.0.1
Jan  2 10:35:32 dnsmasq[8021]: forwarded itavm0002test.muc to 160.XXX.XXX.2
Jan  2 10:35:32 dnsmasq[8021]: reply itavm0002test.muc is <CNAME>
Jan  2 10:35:32 dnsmasq[8021]: reply itavm0002.muc is 10.XXX.XXX.102

Second try:
Jan  2 10:35:38 dnsmasq[8021]: query[A] itavm0002test.muc from 127.0.0.1
Jan  2 10:35:38 dnsmasq[8021]: cached itavm0002test.muc is <CNAME>
Jan  2 10:35:38 dnsmasq[8021]: /etc/hosts itavm0002.muc is 10.XXX.XXX.102

This is also confirmed by tcpduming DNS traffic, and on the second try there is no query sent to the upstream DNS server.

Many thanks!

Cheers,
Janos

Try the dnsmasq git repo, and specifically this commit, which should
fix things.
