Jussi Maki 9948170c8e bpf: Set mac_len in bpf_skb_change_head ... [ Upstream commit 84316ca4e100d8cbfccd9f774e23817cb2059868 ] The skb_change_head() helper did not set "skb->mac_len", which is problematic when it's used in combination with skb_redirect_peer(). Without it, redirecting a packet from a L3 device such as wireguard to the veth peer device will cause skb->data to point to the middle of the IP header on entry to tcp_v4_rcv() since the L2 header is not pulled correctly due to mac_len=0.
