Title:
  ICMPv6 RAs should only be permitted from known routers

Status in OpenStack Neutron (virtual network service):
  Fix Released
Status in OpenStack Security Advisories:
  Invalid

Bug description:
  ICMPv6 is now allowed in from any host but other hosts can offer bogus
  routes.

  Change security group/port filtering to respect known routers:

  - tenant routers attached to subnets and passing v6
  - physical routers on provider networks provided on the network (as some sort of admin configurable list for that network).

  (Security issue: One VM sharing a neutron network can divert outgoing
  traffic from other VMs.)
