#4857 new defect

Disabling an HS with service-side rend circs in progress may produce ‘Internal Error’ log message

From rend_service_rendezvous_has_opened:

  service = rend_service_get_by_pk_digest(
  if (!service) {
    log_warn(LD_GENERAL, "Internal error: unrecognized service ID on "
             "introduction circuit.");
    goto err;

When a hidden service is removed from Tor's configuration, rend_config_services closes its introduction circuits, but not its rendezvous circuits. Leaving in-progress rend circs open can trigger this ‘Internal Error’ log message.

rend_service_set_connection_addr_port will fuss about open rend circs if the client tries to use them again:

  service = rend_service_get_by_pk_digest(
  if (!service) {
    log_warn(LD_REND, "Couldn't find any service associated with pk %s on "
             "rendezvous circuit %d; closing.",
             serviceid, circ->_base.n_circ_id);
    return -1;

But we probably shouldn't close already-open rendezvous circuits (and the open streams on them) when the service goes away; quieting this log message a bit should be enough.

Milestone: Tor: 0.2.3.x-finalTor: 0.2.4.x-final

Harmless, hard-to-trigger warn-level log messages aren't going to be fixed on 0.2.3.x.
