And one more question: What is the reason to deprecate OOT kmod? It’s very comfortable to have an ability to upgrade openvswitch modules separately from the kernel. In case of any bug or requirement for a new feature, we just updated OVN/OVS and kmod-openvswitch and reloaded them. To update kernel on a hypervisors requires much more work: put host into maintenance (avacuate VMs), upgrade, reboot, put back from maintenance. And upgrading the kernel requires full retesting with other components: storage, virtualization, etc...

From the link you’ve sent I see there is a patch in kernel OVS code, but current OVS master still has old version (if (err == NF_ACCEPT && ct->status & IPS_SRC_NAT && ct->status & IPS_DST_NAT)). Shouldn’t this fix be backported to OVS tree as well? Can it solve my initial problem? Just in case, the error is next: 2021-09-03T14:41:42.960Z|00006|dpif(handler3)|WARN|system@ovs-system: execute ct(commit,zone=1,label=0/0x1),set(tunnel(tun_id=0x1400160000f4,dst=<IP>,ttl=64,tp_dst=7471,flags(df|csum|key))),1 failed (Invalid argument) on packet tcp,vlan_tci=0x0000,dl_src=<MAC1>,dl_dst=<MAC2>,nw_src=<IP1>,nw_dst=<IP2>,nw_tos=0,nw_ecn=0,nw_ttl=63,tp_src=54136,tp_dst=5432,tcp_flags=psh|ack tcp_csum:206a with metadata skb_priority(0),skb_mark(0),ct_state(0x21),ct_zone(0x1),ct_tuple4(src=<IP1>,dst=<IP2>,proto=6,tp_src=54136,tp_dst=5432),in_port(4) mtu 0 Thanks. Do you use the OVS in-tree kernel module ? Please check out https://github.com/openvswitch/ovs/blob/master/NEWS#L159 OVS in-tree kernel module is deprecated.
