commit d1fb4238306f854ab610204a50c5cdc20ea5c770 Author: Kevin Benton <[email protected]> Date: Thu Sep 22 23:38:33 2016 -0700 Fixes for missing IPs on subnets in DHCP agent There is a race condition server-side where a port request containing a subnet_id is processed at the same time the subnet is being deleted, the port operation may be successful without having a fixed IP on the requested subnet. This patch makes the DHCP agent resillient to this bug by checking the port response and raising a SubnetMismatchForPort to trigger a resync if it doesn't have all of the requested subnet IDs. Additionally, it avoids skipping assignment of IPv6 addresses to the interface if they are stateless. The original logic to skip assignment was only meant to be for SLAAC addresses. Both of these issues were resulting in the KeyError observed in the bug report.
