Jakub Sitnicki 6e830c2f6c bpf, sockmap: Don't set up upcalls and progs for listening sockets ... Now that sockmap/sockhash can hold listening sockets, when setting up the psock we will (i) grab references to verdict/parser progs, and (2) override socket upcalls sk_data_ready and sk_write_space. However, since we cannot redirect to listening sockets so we don't need to link the socket to the BPF progs. And more importantly we don't want the listening socket to have overridden upcalls because they would get inherited by child sockets cloned from it. Introduce a separate initialization path for listening sockets that does not change the upcalls and ignores the BPF progs.
