BIND 9.11.9-1+ubuntu18.04.1+deb.sury.org+2 crash
The new version crash and the BIND 9.11.8-1+ubuntu18.04.1+deb.sury.org+1 was pulled from the repo. I'm trying the 9.14.4-1 as I need to resume the service but I have GeoIP2 migration problems.

Re: BIND 9.11.9-1+ubuntu18.04.1+deb.sury.org+2 crash
Ok, I installed GeoLite2 databases and adapted named.conf.options and apparmor profile and my service is resumed. It is the second time I'm forced to switch from an ESV version to the lastest version because of a bad update. Bugs is life, but do not pull previous version so quickly. I'm no longer able to help you to debug the 9.11.9 version. All my servers are now on 9.12 or 9.14. Emmanuel.

Re: BIND 9.11.9-1+ubuntu18.04.1+deb.sury.org+2 crash
Hi Emmanuel, the crash should not happen because the discrepancy between the GeoIP and GeoIP2 configurations should have been caught earlier, so I would appreciate if you can submit an issue here: https://gitlab.isc.org/isc-projects/bind9/issues with more details on you named.conf. You can use named-checkconf -px to clean any sensitive data, and/or make sure you mark the issue as confidential if there’s still data you don’t want to be seen by general public. We’ll sanitize the issue later. That said - the 9.11.9-1+ubuntu18.04.1+deb.sury.org+2 backport has missed one important commit that disables legacy GeoIP and enables GeoIP2, and I’ve just uploaded version 3+geoip2 to the Ubuntu repositories, so could you please try again with the recompiled version? It should fix the INSIST() that you were hitting. If that fixes your issue, we would still appreciate if you would create the issue, so we can make BIND fail more gracefully that with an crash if there’s error in the configuration related to the switch between GeoIP and GeoIP2.

Re: BIND 9.11.9-1+ubuntu18.04.1+deb.sury.org+2 crash
The issue was caused by using GeoIP2 configuration with BIND 9.11 compiled with legacy GeoIP, so there’s no need to test it on your side. We are just missing the combination of the options that you have used that caused this, thus the issue. We would be able to test it ourselves then.

Exempt .local from dnssec validation on resolver?
For historical reasons we have some forward-zones defined on our resolver (v9.11.9). For example: zone foo.local {type forward; forwarders { 10.1.2.3; }; zone bar.local {type forward; forwarders { 10.4.5.6; }; These are obviously invalid TLDs, and are defined on servers over which I have no influence or control. The difficulty is if my named.conf contains: dnssec-validation auto; then I'm unable to return records for things like a.foo.local, and my log contains info-messages of the sort: --- lame-servers: info: insecurity proof failed resolving 'foo.local/SOA/IN': 10.1.2.3#53 dnssec: info: validating foo.local/SOA: got insecure response; parent indicates it should be secure --- Is there any way to tell my resolver it shouldn't be validating responses for foo.local? Or must I assert authority over .local and delegate authority for 'foo' and 'bar' back to the servers which are already answering for them? -- Do things because you should, not just because you can.

In 9.14, you can use "validate-except { local; };" (Afterthought: In 9.11, you can also use "rndc nta" to suppress validation on a given domain, but negative trust anchors expire after a while, so you have to keep doing it over and over. You could sign the ".local" zone and distribute a trust anchor for it to all of your internal resolvers. So, I shouldn't have said "no". But the simple fire-and-forget method that you seemed to be looking for was not introduced until 9.14.) -- Evan Hunt -- e...@isc.org Internet Systems Consortium, Inc. ___ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
