[Yahoo-eng-team] [Bug 1622002] Re: dhcp_release6 can be called when it is not present

2016-09-13 Thread Ihar Hrachyshka 
I added Ubuntu dnsmasq package to affected projects to raise visibility
around missing dependency for OpenStack Neutron in Xenial dnsmasq
package.

** Also affects: dnsmasq (Ubuntu)

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.

Fix dhcp_release6 error when not supported

If the system does not have a version of dnsmasq that supports
dhcp_release6, warn about but otherwise handle it gracefully, and also
don't even try to execute it the next time.
