By marking the directory connection as needs_internal, we ensure that the (non-internal!) client-traffic connection won't be sent over the same circuit. --- diff --git a/src/or/circuituse.c b/src/or/circuituse.c index 0ad8b3b51b..df33f63bb9 100644 --- a/src/or/circuituse.c +++ b/src/or/circuituse.c @@ -1229,7 +1229,13 @@ circuit_get_open_circ_or_launch(edge_connection_t *conn, need_uptime = !conn->want_onehop && !conn->use_begindir && smartlist_string_num_isin(options->LongLivedPorts, conn->socks_request->port); - need_internal = desired_circuit_purpose != CIRCUIT_PURPOSE_C_GENERAL; + + if (desired_circuit_purpose != CIRCUIT_PURPOSE_C_GENERAL) + need_internal = 1; + else if (conn->use_begindir || conn->want_onehop) + need_internal = 1; + else + need_internal = 0; circ = circuit_get_best(conn, 1, desired_circuit_purpose, need_uptime, need_internal);
