 Replying to [comment:4 yawning]:

 The relevant location to change would be in
 connection_edge.c:connection_mark_unattached_ap_() I believe.

 I'd try to do it in parse_socks() when we say
 {{{
         /* not a connect or resolve or a resolve_ptr? we don't support it.
 */
         log_warn(LD_APP,"socks5: command %d not recognized. Rejecting.",
                  req->command);
         return -1;
 }}}

 Set req->reply and req->replylen and then
 connection_ap_handshake_process_socks() will send it for you.
