[Patch bpf-next v7 09/13] udp: implement ->read_sock() for sockmap

From: Cong Wang This is similar to tcp_read_sock(), except we do not need to worry about connections, we just need to retrieve skb from UDP receive queue. Note, the return value of ->read_sock() is unused in sk_psock_verdict_data_ready(). Cc: John Fastabend Cc: Daniel Borkmann Cc: Jakub Sitni
