Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1498370 Title: [SRU] DHCP agent: interface unplug leads to exception Status in neutron: Fix Released Status in neutron package in Ubuntu: Fix Released Status in neutron source package in Trusty: New Status in neutron source package in Vivid: In Progress Status in neutron source package in Wily: Fix Released Status in neutron source package in Xenial: Fix Released Bug description: [Impact] There are edge cases when the DHCP agent attempts to unplug an interface and the device does not exist. This patch ensures that the agent can tolerate this case. [Test Case] * create subnet with dhcp enabled * set pdb.set_trace() in neutron.agent.linux.dhcp.DeviceManager.destroy() * manually delete ns-<id> device in tenant namespace * pdb continue and should not raise any error [Regression Potential] None 2015-09-22 01:23:42.612 ERROR neutron.agent.dhcp.agent [-] Unable to disable dhcp for c543db4d-e077-488f-b58c-5805f63f86b6. 2015-09-22 01:23:42.612 TRACE neutron.agent.dhcp.agent Traceback (most recent call last): 2015-09-22 01:23:42.612 TRACE neutron.agent.dhcp.agent File "/opt/stack/neutron/neutron/agent/dhcp/agent.py", line 115, in call_driver 2015-09-22 01:23:42.612 TRACE neutron.agent.dhcp.agent getattr(driver, action)(**action_kwargs) 2015-09-22 01:23:42.612 TRACE neutron.agent.dhcp.agent File "/opt/stack/neutron/neutron/agent/linux/dhcp.py", line 221, in disable 2015-09-22 01:23:42.612 TRACE neutron.agent.dhcp.agent self._destroy_namespace_and_port() 2015-09-22 01:23:42.612 TRACE neutron.agent.dhcp.agent File "/opt/stack/neutron/neutron/agent/linux/dhcp.py", line 226, in _destroy_namespace_and_port 2015-09-22 01:23:42.612 TRACE neutron.agent.dhcp.agent self.device_manager.destroy(self.network, self.interface_name) 2015-09-22 01:23:42.612 TRACE neutron.agent.dhcp.agent File "/opt/stack/neutron/neutron/agent/linux/dhcp.py", line 1223, in destroy 2015-09-22 01:23:42.612 TRACE neutron.agent.dhcp.agent self.driver.unplug(device_name, namespace=network.namespace) 2015-09-22 01:23:42.612 TRACE neutron.agent.dhcp.agent File "/opt/stack/neutron/neutron/agent/linux/interface.py", line 358, in unplug 2015-09-22 01:23:42.612 TRACE neutron.agent.dhcp.agent tap_name = self._get_tap_name(device_name, prefix) 2015-09-22 01:23:42.612 TRACE neutron.agent.dhcp.agent File "/opt/stack/neutron/neutron/agent/linux/interface.py", line 299, in _get_tap_name 2015-09-22 01:23:42.612 TRACE neutron.agent.dhcp.agent dev_name = dev_name.replace(prefix or self.DEV_NAME_PREFIX, 2015-09-22 01:23:42.612 TRACE neutron.agent.dhcp.agent AttributeError: 'NoneType' object has no attribute 'replace' 2015-09-22 01:23:42.612 TRACE neutron.agent.dhcp.agent 2015-09-22 01:23:42.616 INFO neutron.agent.dhcp.agent [-] Synchronizing state complete The reason is the device is None To manage notifications about this bug go to: https://bugs.launchpad.net/neutron/+bug/1498370/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : yahoo-eng-team@lists.launchpad.net Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
