The following test was performed. - Upon adapter registration, the info line of creating an ADV monitor manager gets printed, and system bus emits the interface events of org.bluez.AdvertisementMonitorManager1. Reviewed-by: Yun-Hao Chung Reviewed-by: Manish Mandlik Reviewed-by: Abhishek Pandit-Subedi --- (no changes since v4) Changes in v4: -Create the Adv Monitor Manager only if the experimental flag is in place and mark all properties and methods experimental. Changes in v2: -Use new0 instead of g_new0 -Remove the reset of manager members -Make methods/property experimental Makefile.am | 3 +- src/adapter.c | 23 ++++++++ src/adv_monitor.c | 147 ++++++++++++++++++++++++++++++++++++++++++++++ src/adv_monitor.h | 32 ++++++++++ 4 files changed, 204 insertions(+), 1 deletion(-) create mode 100644 src/adv_monitor.c create mode 100644 src/adv_monitor.h diff --git a/Makefile.am b/Makefile.am index 725fbe48d..22b4fa30c 100644 --- a/Makefile.am +++ b/Makefile.am @@ -293,7 +293,8 @@ src_bluetoothd_SOURCES = $(builtin_sources) \ src/gatt-client.h src/gatt-client.c \ src/device.h src/device.c \ src/dbus-common.c src/dbus-common.h \ - src/eir.h src/eir.c + src/eir.h src/eir.c \ + src/adv_monitor.h src/adv_monitor.c src_bluetoothd_LDADD = lib/libbluetooth-internal.la \ gdbus/libgdbus-internal.la \ src/libshared-glib.la \ diff --git a/src/adapter.c b/src/adapter.c index 1435e2bd7..df628a7fd 100644 --- a/src/adapter.c +++ b/src/adapter.c @@ -77,6 +77,7 @@ #include "attrib-server.h" #include "gatt-database.h" #include "advertising.h" +#include "adv_monitor.h" #include "eir.h" #define ADAPTER_INTERFACE "org.bluez.Adapter1" @@ -272,6 +273,8 @@ struct btd_adapter { struct btd_gatt_database *database; struct btd_adv_manager *adv_manager; + struct btd_adv_monitor_manager *adv_monitor_manager; + gboolean initialized; GSList *pin_callbacks; @@ -6360,6 +6363,9 @@ static void adapter_remove(struct btd_adapter *adapter) btd_adv_manager_destroy(adapter->adv_manager); adapter->adv_manager = NULL; + btd_adv_monitor_manager_destroy(adapter->adv_monitor_manager); + adapter->adv_monitor_manager = NULL; + g_slist_free(adapter->pin_callbacks); adapter->pin_callbacks = NULL; @@ -8633,6 +8639,23 @@ static int adapter_register(struct btd_adapter *adapter) adapter->adv_manager = btd_adv_manager_new(adapter, adapter->mgmt); + if (g_dbus_get_flags() & G_DBUS_FLAG_ENABLE_EXPERIMENTAL) { + if (adapter->supported_settings & MGMT_SETTING_LE) { + adapter->adv_monitor_manager = + btd_adv_monitor_manager_create(adapter, + adapter->mgmt); + if (!adapter->adv_monitor_manager) { + btd_error(adapter->dev_id, + "Failed to create Adv Monitor " + "Manager for adapter"); + return -EINVAL; + } + } else { + btd_info(adapter->dev_id, "Adv Monitor Manager " + "skipped, LE unavailable"); + } + } + db = btd_gatt_database_get_db(adapter->database); adapter->db_id = gatt_db_register(db, services_modified, services_modified, diff --git a/src/adv_monitor.c b/src/adv_monitor.c new file mode 100644 index 000000000..ad3f64cbe --- /dev/null +++ b/src/adv_monitor.c @@ -0,0 +1,147 @@ +/* + * + * BlueZ - Bluetooth protocol stack for Linux + * + * Copyright (C) 2020 Google LLC + * + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public + * License as published by the Free Software Foundation; either + * version 2.1 of the License, or (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
