commit 494b65d951dbc03f4cebb3bc14970e54ff6adb5f Author: Yang JianFeng <[email protected]> Date: Thu May 16 17:40:28 2019 +0800 Optimize the code that fixes the race condition of DHCP agent. https://review.opendev.org/#/c/236983/ https://review.opendev.org/#/c/606383/ The above patchs that resolve the race condition of DHCP agent will result in neutron-server raise DhcpPortInUse ERROR log. And, the second patch may result in old dhcp agent create a redundant port.

Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1829332 Title: neutron-server report DhcpPortInUse ERROR log Status in neutron: Fix Released Bug description: In our environment, the /var/log/neutron/server.log occasionally report the following error: http://paste.openstack.org/show/751456/ I found it is resulted by https://review.opendev.org/#/c/236983/ and https://review.opendev.org/#/c/606383/. The two patches resolved they closed bug, but I think their solutions are not perfect. They may result in the following issues: 1. Result in neutron-server raise ERROR log 2. If we encounter the case: https://bugs.launchpad.net/neutron/+bug/1795126, the old agent may create a redundant port. Because of the neutron-dhcp-agent may create a new port after it received DhcpPortInUse exception. So, I think we should optimize these codes.
