Shouldn't ip_output also use the path variant, dst_mtu(skb->dst->path), 
it's surely after ipsec- processing?
   

That's the reason why it shouldn't use dst->path.  The only time you
should use dst_mtu(dst->path) is when dst may contain IPsec AND you
need the MTU outside IPsec.

In this case dst cannot contain IPsec so dst_mtu(dst) is correct.

ok I see it now, but this is really easy to get wrong...
