Lorenz Bauer 3990408470 bpf: add helper to check for a valid SYN cookie ... Using bpf_skc_lookup_tcp it's possible to ascertain whether a packet belongs to a known connection. However, there is one corner case: no sockets are created if SYN cookies are active. This means that the final ACK in the 3WHS is misclassified. Using the helper, we can look up the listening socket via bpf_skc_lookup_tcp and then check whether a packet is a valid SYN cookie ACK.
