kern :warn : [  173.147759] WARNING: CPU: 12 PID: 2260 at net/core/flow_dissector.c:1096 __skb_flow_dissect (net/core/flow_dissector.c:1096 (discriminator 1)) 

Two options, more 'guess the right netns' in flow dissector:
derive netns from skb->dst->dev.

Or, pass struct net down to xfrm session decode functions.

I'll have a go at option 2 to see how much noise its going to be.
