Sebastian Andrzej Siewior fecef4cd42 tun: Assign missing bpf_net_context. ... During the introduction of struct bpf_net_context handling for XDP-redirect, the tun driver has been missed. Jakub also pointed out that there is another call chain to do_xdp_generic() originating from netif_receive_skb() and drivers may use it outside from the NAPI context. Set the bpf_net_context before invoking BPF XDP program within the TUN driver. Set the bpf_net_context also in do_xdp_generic() if a xdp program is available.
