Paul Chaignon b8fff74852 bpf: Set flow flag to allow any source IP in bpf_tunnel_key ... Commit 26101f5ab6 ("bpf: Add source ip in "struct bpf_tunnel_key"") added support for getting and setting the outer source IP of encapsulated packets via the bpf_skb_{get,set}_tunnel_key BPF helper. This change allows BPF programs to set any IP address as the source, including for example the IP address of a container running on the same host. In that last case, however, the encapsulated packets are dropped when looking up the route because the source IP address isn't assigned to any interface on the host. To avoid this, we need to set the FLOWI_FLAG_ANYSRC flag.
