Subject: Re: [PATCHv3 net 4/4] openvswitch: Serialize nested ct actions if

From: Joe Stringer <>
Date: Mon, 19 Oct 2015 19:19:00 -0700

> If userspace provides a ct action with no nested mark or label, then the
> storage for these fields is zeroed. Later when actions are requested,
> such zeroed fields are serialized even though userspace didn't
> originally specify them. Fix the behaviour by ensuring that no action is
> serialized in this case, and reject actions where userspace attempts to
> set these fields with mask=0. This should make netlink marshalling
> consistent across deserialization/reserialization.
