Eric Dumazet 60ce37b039 bpf, sockmap: Do not ignore orig_len parameter ... Currently, sk_psock_verdict_recv() returns skb->len This is problematic because tcp_read_sock() might have passed orig_len < skb->len, due to the presence of TCP urgent data. This causes an infinite loop from tcp_read_sock() Followup patch will make tcp_read_sock() more robust vs bad actors.
