Title:
hairpin mode on vnet bridge ports causes false positives on IPv6
duplicate address detection
Status in OpenStack Compute (Nova):
Fix Released
Status in OpenStack Compute (nova) havana series:
In Progress
Bug description:
This is bug 1011134 again happening in a cloud that does not have the ipv6
flag set,
so the previous patch from https://review.openstack.org/14017
is not used.
Guest VMs will try to configure IPv6 link-local addrs even without the outer
parts supporting it
and can throw errors when they see inbound packets with their own MAC address.
Note: I think, this bug can not be unit-tested as it requires a
complex setup including running a VM in a cloud.
