[DCCP]: Set socket owner iff packet is not data
Here is a complimentary insurance policy for those feeling a bit insecure. You don't have to accept this. However, if you do, you can't blame me for it :) > 1) dccp_transmit_skb sets the owner for all packets except data packets. We can actually verify this by looking at pkt_type.
