[SRU] Some DNS extensions not working with OVN

[Dr. Jens Harbott]

[Impact]

On a fresh devstack install with the q-dns service enable from the neutron devstack plugin, some features still don't work, e.g.:

$ openstack subnet set private-subnet --dns-publish-fixed-ip
BadRequestException: 400: Client Error for url: https://10.250.8.102:9696/v2.0/subnets/9f50c79e-6396-4c5b-be92-f64aa0f25beb, Unrecognized attribute(s) 'dns_publish_fixed_ip'

$ openstack port create p1 --network private --dns-name p1 --dns-domain a.b.
BadRequestException: 400: Client Error for url: https://10.250.8.102:9696/v2.0/ports, Unrecognized attribute(s) 'dns_domain'

The reason seems to be that https://review.opendev.org/c/openstack/neutron/+/686343/31/neutron/common/ovn/extensions.py only added dns_domain_keywords, but not e.g. dns_domain_ports as supported by OVN

[Test Case]

Create a normal OpenStack neutron test environment to see if we can successfully run the following commands:

openstack subnet set private_subnet --dns-publish-fixed-ip
openstack port create p1 --network private --dns-name p1 --dns-domain a.b.

[Regression Potential]

The fix has merged into the upstream stable/xena branch [1], here's just SRU into the 19.1.0 branch of UCA xena (the fix is already in 20.0.0 so it's already in jammy and kinetic and focal-yoga), so it is a clean backport and might be helpful for deployments migrating to OVN.

    Fix list of DNS extensions supported by OVN

    The OVN driver needs to announce all DNS extensions as supported,
    otherwise the neutron server will reject them.

Can anyone add 'ubuntu cloud archive xena' project? It seems that I don't have permission to do it, thanks

This issue was fixed in the openstack/neutron 19.3.0 release.

[Edward Hope-Morley (hopem)]

this is releases in all but xena which will be available in the Ubuntu Cloud Archive in the upcoming 19.0.3 stable release

[Diko Parvanov (dparv)]

We are hitting this also on focal/ussuri with neutron 16.4.2-0ubuntu1 - is there supposed to be a backport for this?

[Edward Hope-Morley (hopem)]

Added U/V/W for backport.

Hello,

I don't know if I should open a new bug but this bug affects ML2 plugin too.

$ openstack network set --dns-domain demo.domain.tld. 0f133524-ac0c-4444-bbb-9777ffec81ce

$ openstack subnet set --dns-publish-fixed-ip 4687aaad-4000-4f4d-aacc-46f8e9daaaa
BadRequestException: 400: Client Error for url: http:/cloud.domain.tld:9696/v2.0/subnets/4687aaad-4000-4f4d-aacc-46f8e9daaaa, Unrecognized attribute(s) 'dns_publish_fixed_ip'

# dpkg -l | grep neutron
ii neutron-common 2:19.4.0-0ubuntu1~cloud0 all Neutron is a virtual network service for Openstack - common

Distro: ubuntu:focal

I'm not aware about your priority but this feature is supposed to fix a bug from 2018. You will find below the previous launchpad:
