Jon Maloy d618d09a68 tipc: enforce valid ratio between skb truesize and contents ... The socket level flow control is based on the assumption that incoming buffers meet the condition (skb->truesize / roundup(skb->len) <= 4), where the latter value is rounded off upwards to the nearest 1k number. This does empirically hold true for the device drivers we know, but we cannot trust that it will always be so, e.g., in a system with jumbo frames and very small packets. We now introduce a check for this condition at packet arrival, and if we find it to be false, we copy the packet to a new, smaller buffer, where the condition will be true. We expect this to affect only a small fraction of all incoming packets, if at all.
