Ah, I see, we do call the original ->sk_data_ready() when redirecting the packet, via sk_psock_data_ready(), however it looks like those ->poll() still reads the original queues (e.g. ->sk_receive_queue) but misses the sockmap queues (psock->ingress_skb). Let me think about the right fix of this. Thanks a lot for the details!
