Hi all,
I've found out that dnsmasq < 2.67 does not work properly for IPv6
clients when it comes to MAC address matching (it fails to match, and
so clients get 'no addresses available' response). I've requested
version bump to 2.67 in: https://review.openstack.org/145482
Now, since we've already released Juno with IPv6 DHCP stateful
support, and DHCP agent still has minimal version set to 2.63 there,
we have a dilemma on how to manage it from stable perspective.
Obviously, we should communicate the revealed version dependency to
deployers via next release notes.
Should we also backport the minimal version bump to Juno? This will
result in DHCP agent failing to start in case packagers don't bump
dnsmasq version with the next Juno release. If we don't bump the
version, we may leave deployers uninformed about the fact that their
IPv6 stateful instances won't get any IPv6 address assigned.
An alternative is to add a special check just for Juno that would WARN
administrators instead of failing to start DHCP agent.
Sent Juno fix for review: https://review.openstack.org/145784
