Commit 2aa23de58f added in a warning
in the event that a release failed. This would have no information
that can help anyone deal with it.
Also updated the release note to include a recommendation to use
a version of dnsmasq including dhcp_release6 on an upgrade, so
that the warning we are logging here will not happen.

prelude: >
|
|
- Call dhcp_release6 command line utility when releasing
|
|
unused IPv6 leases for DHCPv6 stateful subnets.
|
|
dhcp_release6 first appeared in dnsmasq 2.76
|
|
upgrade:
|
|
- A version of dnsmasq that includes dhcp_release6 should
|
|
be installed on systems running the DHCP agent. Failure
|
|
to do this could cause DHCPv6 stateful addressing to
|
|
not function properly.
|
|
- The rootwrap filters file dhcp.filters must be updated
|
|
to include dhcp_release6, otherwise trying to run the
|
|
utility will result in a NoFilterMatched exception.
|
|
issues:
|
|
- Absence of dhcp_release6 when DHCPv6 stateful addressing
|
|
is in use may lead to bug `1521666 <https://bugs.launchpad.net/neutron/+bug/1521666>`_.
|
|
Neutron supports dhcp_release6 now, but if the tool is
|
|
not available this leads to increased log warnings. Read
|
|
bug report `1622002 <https://bugs.launchpad.net/neutron/+bug/1622002>`_
