Hi Savario, Thanks again for getting your patch upstream. The upstream patches have landed for master, newton, and mitaka, so I've picked those patches into our packages and uploaded to zesty, yakkety, and xenial. yakkety and xenial are awaiting SRU team review before they'll be accepted into the -proposed pockets for testing. Once those get accepted we can get those backported to corresponding cloud archives, and start the backport to the liberty cloud archive.
** Summary changed: - When router has no ports _process_updated_router fails because the namespace does not exist + [SRU] When router has no ports _process_updated_router fails because the namespace does not exist ** Description changed: + [Description] + [Testcase] Happens in Kilo. Cannot test on other releases. Steps to reproduce: 1) create a router and set at least a port, also the gateway is fine 2) check that the namespace exists with - ip netns show | grep qrouter-<uuid> + ip netns show | grep qrouter-<uuid> 3) check the ports are there - ip netns exec qrouter-<uuid> ip addr show + ip netns exec qrouter-<uuid> ip addr show 4) delete all ports from the router 5) check that only loopback interface is present - ip netns exec qrouter-<uuid> ip addr show + ip netns exec qrouter-<uuid> ip addr show 6) run the cronjob task that is installed in the file - /etc/cron.d/neutron-l3-agent-netns-cleanup - so basically run this command: - /usr/bin/neutron-netns-cleanup --config-file=/etc/neutron/neutron.conf --config-file=/etc/neutron/l3_agent.ini + /etc/cron.d/neutron-l3-agent-netns-cleanup + so basically run this command: + /usr/bin/neutron-netns-cleanup --config-file=/etc/neutron/neutron.conf --config-file=/etc/neutron/l3_agent.ini 7) the namespace should be gone: - ip netns show | grep qrouter-<uuid> + ip netns show | grep qrouter-<uuid> 8) delete the neutron router. 9) check log file /var/log/neutron/vpn-agent.log - - When the router has no ports the namespace is deleted from the network node by the cronjob. However this brakes the router updates and the file vpn-agent.log is flooded with this traces: + When the router has no ports the namespace is deleted from the network + node by the cronjob.
