+Subject: [PATCH] fix coredump during ifp reconnect
+
+When the responder reconnects and gets old information in the service list (get_service_in_the_list), 
+the corresponding socket_activated flag will be set to false (svc->socket_activated = false).
+The above behavior caused the main process to exit (monitor_quit), 
+did not set the corresponding destructor to NULL (talloc_set_destructor(svc->conn, NULL)), 
+and finally caused double-free during destructor, resulting in coredump.
+Therefore, it is necessary to set the corresponding socket_activated flag to true at the end of the responder service reconnection.
+
+In fact, all services should have the above settings, but I have only reproduced the coredump scenario after ifp reconnection, 
+and other responders have not been tested for reproduction. 
+In order to keep the minimum modification, an if judgment is added here, and only the scene of ifp is processed.
+The complete solution to this problem requires further optimization of the socket_activated setting mechanism.
