The Program Committee has accepted another nutsnbolts talk. Dynamic skb metadata extension is a refreshing new feature added upstream recently (see commit df5042f4c5b9). A net subsystem can associate metadatum to an skb through its life span without affecting the size of the sk_buff structure. Oh, the things you can do with this new found freedom! Florian Westphal will go into the deep guts of this feature and then digest it to make it tasty for your consumption. Come see him in action.
