Herbert Xu deea84b0ae [NET]: Fix SKB_WITH_OVERHEAD calculation ... The calculation in SKB_WITH_OVERHEAD is incorrect in that it can cause an overflow across a page boundary which is what it's meant to prevent. In particular, the header length (X) should not be lumped together with skb_shared_info. The latter needs to be aligned properly while the header has no choice but to sit in front of wherever the payload is. Therefore the correct calculation is to take away the aligned size of skb_shared_info, and then subtract the header length. The resulting quantity L satisfies the following inequality: SKB_DATA_ALIGN(L + X) + sizeof(struct skb_shared_info) <= PAGE_SIZE This is the quantity used by alloc_skb to do the actual allocation.
