Gavin Grant 93a972f854 slirp: Propagate host TCP RST packet to the guest after socket disconnected ... Commit 27d92ebc5e handled the case where the TCP connection is abruptly closed via a RST packet, by checking for the ECONNRESET errno. However it does not consider the case where the connection has been half-closed by the host (FIN/ACK), then the host socket is disconnected. For example, if the host application calls close() on the socket, then the application exits. In this case, the socket still exists due to the file descriptor in SLIRP, but it is disconnected. recv() does not indicate an error since an orderly socket close has previously occurred. The socket will then be stuck in FIN_WAIT_2, until the peer sends FIN/ACK or a timeout occurs. Instead we can send a RST to the peer and transition to the CLOSED state.
