hi, In sockmap case, when sender send msg, In function sk_psock_queue_msg(), it will put the msg into the receiver psock ingress_msg queue, and wakeup receiver to receive. sender can always send msg but not aware the receiver psock ingress_msg queue size. In mortally case, when receiver not receive again due to the application bug, sender can contiunous send msg unti system memory not enough. If this happen, it will influence the whole system. my question is: is there a better solution for this case? just like tcp use sk_sendbuf to limit the sender to send agagin if receiver is block. thanks very much.
