John Fastabend b05545e15e bpf: sockmap, fix transition through disconnect without close ... It is possible (via shutdown()) for TCP socks to go trough TCP_CLOSE state via tcp_disconnect() without actually calling tcp_close which would then call our bpf_tcp_close() callback. Because of this a user could disconnect a socket then put it in a LISTEN state which would break our assumptions about sockets always being ESTABLISHED state. To resolve this rely on the unhash hook, which is called in the disconnect case, to remove the sock from the sockmap.
