After doing some bisection I found the following commit to introduce the problem:
120645513f55a4ac5543120d9e79925d30a0156f is the first bad commit commit 120645513f55a4ac5543120d9e79925d30a0156f Author: Jarno Rajahalme <[email protected]> Date: Fri Apr 21 16:48:06 2017 -0700 openvswitch: Add eventmask support to CT action. Add a new optional conntrack action attribute OVS_CT_ATTR_EVENTMASK, which can be used in conjunction with the commit flag (OVS_CT_ATTR_COMMIT) to set the mask of bits specifying which conntrack events (IPCT_*) should be delivered via the Netfilter netlink multicast groups. Default behavior depends on the system configuration, but typically a lot of events are delivered. This can be very chatty for the NFNLGRP_CONNTRACK_UPDATE group, even if only some types of events are of interest. Netfilter core init_conntrack() adds the event cache extension, so we only need to set the ctmask value. However, if the system is configured without support for events, the setting will be skipped due to extension not being found.
