Each individual byte array represents a raw SDP record, as defined by the Bluetooth Service Discovery Protocol spec. This method is intended to be only used by compatibility layers like Wine, that need to provide access to raw SDP records to implement the Win32 Bluetooth API. Applications should instead use the Profile API for services-related functionality. --- src/device.c | 83 ++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 83 insertions(+) diff --git a/src/device.c b/src/device.c index 0f18c8c7f..6aa809c80 100644 --- a/src/device.c +++ b/src/device.c @@ -3215,6 +3215,86 @@ static DBusMessage *cancel_pairing(DBusConnection *conn, DBusMessage *msg, return dbus_message_new_method_return(msg); } +static sdp_list_t *read_device_records(struct btd_device *device); + +static DBusMessage *get_service_records(DBusConnection *conn, DBusMessage *msg, + void *data) +{ + DBusMessage *reply; + DBusMessageIter records_arr, record; + struct btd_device *device = data; + sdp_list_t *cur; + + if (!btd_adapter_get_powered(device->adapter)) + return btd_error_not_ready(msg); + + if (!btd_device_is_connected(device)) + return btd_error_not_connected(msg); + + if (!device->bredr_state.svc_resolved) + return btd_error_not_ready(msg); + + if (!device->tmp_records) { + device->tmp_records = read_device_records(device); + if (!device->tmp_records) + return btd_error_does_not_exist(msg); + } + + reply = dbus_message_new_method_return(msg); + if (!reply) + return btd_error_failed(msg, "Could not create method reply"); + + dbus_message_iter_init_append(reply, &records_arr); + if (!dbus_message_iter_open_container(&records_arr, DBUS_TYPE_ARRAY, + "ay", &record)) { + dbus_message_unref(reply); + return btd_error_failed(msg, "Could not initialize iterator"); + } + + for (cur = device->tmp_records; cur; cur = cur->next) { + DBusMessageIter record_bytes; + sdp_record_t *rec = cur->data; + sdp_buf_t buf; + int result; + + result = sdp_gen_record_pdu(rec, &buf); + if (result) { + dbus_message_iter_abandon_container(&records_arr, + &record); + dbus_message_unref(reply); + return btd_error_failed( + msg, "Could not marshal service record"); + } + if (!dbus_message_iter_open_container(&record, DBUS_TYPE_ARRAY, + "y", &record_bytes)) { + bt_free(buf.data); + dbus_message_iter_abandon_container(&records_arr, + &record); + dbus_message_unref(reply); + return btd_error_failed( + msg, "Could not initialize iterator"); + } + if (!dbus_message_iter_append_fixed_array( + &record_bytes, DBUS_TYPE_BYTE, &buf.data, + buf.data_size)) { + bt_free(buf.data); + dbus_message_iter_abandon_container(&record, + &record_bytes); + dbus_message_iter_abandon_container(&records_arr, + &record); + dbus_message_unref(reply); + return btd_error_failed( + msg, "Could not append record data to reply"); + } + dbus_message_iter_close_container(&record, &record_bytes); + bt_free(buf.data); + } + + dbus_message_iter_close_container(&records_arr, &record); + + return reply; +} + static const GDBusMethodTable device_methods[] = { { GDBUS_ASYNC_METHOD("Disconnect", NULL, NULL, dev_disconnect) }, { GDBUS_ASYNC_METHOD("Connect", NULL, NULL, dev_connect) }, @@ -3224,6 +3304,9 @@ static const GDBusMethodTable device_methods[] = { NULL, disconnect_profile) }, { GDBUS_ASYNC_METHOD("Pair", NULL, NULL, pair_device) }, { GDBUS_METHOD("CancelPairing", NULL, NULL, cancel_pairing) }, + { GDBUS_EXPERIMENTAL_METHOD("GetServiceRecords", NULL, + GDBUS_ARGS({ "Records", "aay" }), + get_service_records) }, { } };
