commit ff3132d8d455012b2b29f1eb65817f8492f84fe9 Author: Kevin Benton <[email protected]> Date: Fri Mar 3 10:57:57 2017 -0800 Stop killing conntrack state without CT Zone The conntrack clearing code was belligerenty killing connections without a conntrack zone specifier when it couldn't get the zone for a given device. This means it would kill all connections based on an IP address match, which meant hitting innocent bystanders in other tenant networks with overlapping IP addresses. This bad fallback was being triggered every time because it was using the wrong identifier for a port to look up the zone. This patch fixes the port lookup and adjusts the fallback behavior to never clear conntrack entries if we can't find the conntrack zone for a port. This triggered the bug below (in the cases I root-caused) by killing a metadata connection right in the middle of retrieving a key.

Number attempts: 16. Retry after 17 seconds. I traced it down to the VM not getting keys back from the metadata service even though it has a keypair configured. The request makes it over to Nova metadata with the relevant instance ID but no keys are being returned.
