This will wrap the inner packet into a tunnel header with the key bit and value set accordingly. This is problematic when using a tunnel protocol that supports optional tunnel keys and a receiving tunnel device that is not expecting packets with the key bit set.

This enables us to redirect packets between tunnel interfaces - and potentially change the encapsulation clockwork mdWeb27 Jul 2024 · Because the BPF capture filter does not support GRE as a filter, anything on top of that can only be filtered by checking the data at known positions. So with the layers IP (20) / GRE (4) / IP (20) / UDP, the UDP source port is at position 20+4+20 = 44 bytes. Then the filter you can use is: ip proto 47 and (ip[44:2] == 1234 or ip[46:2] == 1234) clock work mathsWebThe bpf_skb_set_fou_encap kfunc is supposed to be used in tandem and after a successful call to the bpf_skb_set_tunnel_key bpf-helper.
