We do use OOT module.

Looks like it’s a bugfix and can be backported..?

Hi Ilya, Dumitru,

for some reason I’ve found your answer only today.

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:

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.

Thanks
