Putting that into shinfo should work fine. I thought extending that structure with information that isn't needed for all packets was as bad as extending sk_buff itself. If that isn't the case, then extending shinfo definitely is the simplest solution.
Not at all, the sk_buff has its own slab while skb->head uses kmalloc. The latter has loads of free space due to padding for common MTUs such as 1500 or header-only.
