commit 70907b3e5513828c330425d7629dae71d632ac72 Author: Kevin Benton <[email protected]> Date: Mon Sep 19 16:02:45 2016 -0700 Always cleanup stale devices on DHCP setup failure If the DHCP port setup process fails in the DHCP agent device manager, it will throw a conflict exception, which will bubble all of the way up to the main DHCP agent. The issue is that, during a 'restart' call, the config files are wiped out while maintaining the VIF before calling setup. This means that, if setup fails, there is no reference to the interface name anymore so a subsequent destroy will not first unplug the VIF before destroying the namespace. This leaves a bunch of orphaned tap ports behind in the OVS case that don't have an accessible namespace. This patch addresses the issue by cleaning up all ports inside of a namespace on a 'setup' failure before reraising the exception. This ensures that the namespace is clear if destroy is called in the future without another successful setup.

This seems to be associated to traces like below, where two separate interfaces get associated to the same ofport right about the same time: 2016-09-19T17:34:48.065Z|00247|bridge|INFO|bridge br-int: added interface qvo9d9ab7b1-59 on port 89 2016-09-19T17:34:48.077Z|00248|bridge|INFO|bridge br-int: added interface tapc9e6d02e-2c on port 89 We need to figure out what's causing it, and fix it for good.
