Comment 1 Brian Haley 2018-05-23 15:53:53 UTC
dhcp_release6 is something neutron could call to try and clean-up stale leases, so it should be allowed.  Since it's not something that would happen often, and it's IPv6 which doesn't have as small a subnet size as IPv4, I wouldn't necessarily consider it a blocker for GA.  And it is probably just causing a runtime error in the dhcp-agent, which should be caught correctly.

Comment 2 Bernard Cafarelli 2018-05-23 16:21:41 UTC
May be related to #1547669 (now dhcp_release6 binary is found and can be called)

Comment 3 Brian Haley 2018-05-23 16:29:30 UTC
Yes, Bernard is correct, dhcp_release6 was added in dnsmasq version 2.76, http://www.thekelleys.org.uk/dnsmasq/CHANGELOG - so that script is new to any OSP release that gets it.

Comment 10 Lon Hohberger 2018-06-21 13:01:11 UTC
AVC regression tests for this passed; the AVC does not appear with current openstack-selinux-0.8.14-11.el7ost and later
