Title:
dhcp_release6 can be called when it is not present
Status in neutron:
In Progress
Status in dnsmasq package in Ubuntu:
New
Bug description:
If someone enables dhcpv6-stateful addressing on a subnet, but they
are running an old version of dnsmasq (<2.76), then the dhcp agent
could try and run dhcp_release6 even though it isn't present. An
example:
http://logs.openstack.org/53/365653/5/check/gate-tempest-dsvm-neutron-
multinode-full-ubuntu-
xenial/813d16d/logs/screen-q-dhcp.txt.gz#_2016-09-06_11_40_02_272
Checking it's present first would fix this problem.
Since the change to call dhcp_release6 was just added in
https://review.openstack.org/#/c/301747/ we should fix this before
Newton ships and people complain.
There is also an effort to get Cirros to support DHCPv6 so that we can test
this in the gate,
https://bugs.launchpad.net/cirros/+bug/1487041 - hopefully that gets done so
we can add a functional test.
