From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Rafal Michalski To: linux-bluetooth@vger.kernel.org Cc: Rafal Michalski Subject: [PATCH v5] Fix disconnect devices after enabling offline mode Date: Wed, 1 Jun 2011 15:13:08 +0200 Message-Id: <1306933988-23209-1-git-send-email-michalski.raf@gmail.com> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: Previously paired and connected devices were disconnected automatically after turning bluetooth off directly via bluetooth UI. This patch makes that also other ways of turning bluetooth off (which should lead to disconnecting paired and connected devices), such as enabling offline mode (which turns bluetooth off as well), can be handled properly. --- src/adapter.c | 40 ++++++++++++++++++++++++++++++++++++++++ 1 files changed, 40 insertions(+), 0 deletions(-) diff --git a/src/adapter.c b/src/adapter.c index c30febc..bb2643c 100644 --- a/src/adapter.c +++ b/src/adapter.c @@ -77,6 +77,8 @@ #define check_address(address) bachk(address) +#define OFF_TIMER 3 + static DBusConnection *connection = NULL; static GSList *adapter_drivers = NULL; @@ -142,6 +144,8 @@ struct btd_adapter { gint ref; + guint off_timer; + GSList *powered_callbacks; gboolean name_stored; @@ -2331,6 +2335,7 @@ void btd_adapter_start(struct btd_adapter *adapter) adapter->pairable_timeout = get_pairable_timeout(address); adapter->state = STATE_IDLE; adapter->mode = MODE_CONNECTABLE; + adapter->off_timer = 0; if (main_opts.le) adapter_ops->enable_le(adapter->dev_id); @@ -2504,6 +2509,12 @@ int btd_adapter_stop(struct btd_adapter *adapter) return 0; } +static void off_timer_remove(struct btd_adapter *adapter) +{ + g_source_remove(adapter->off_timer); + adapter->off_timer = 0; +} + static void adapter_free(gpointer user_data) { struct btd_adapter *adapter = user_data; @@ -2516,6 +2527,9 @@ static void adapter_free(gpointer user_data) if (adapter->auth_idle_id) g_source_remove(adapter->auth_idle_id); + if (adapter->off_timer) + off_timer_remove(adapter); + sdp_list_free(adapter->services, NULL); g_slist_foreach(adapter->found_devices, (GFunc) dev_info_free, NULL); @@ -3454,6 +3468,16 @@ int btd_adapter_restore_powered(struct btd_adapter *adapter) return adapter_ops->set_powered(adapter->dev_id, TRUE); } +static gboolean switch_off_timeout(gpointer user_data) +{ + struct btd_adapter *adapter = user_data; + + adapter_ops->set_powered(adapter->dev_id, FALSE); + adapter->off_timer = 0; + + return FALSE; +} + int btd_adapter_switch_online(struct btd_adapter *adapter) { if (!adapter_ops) @@ -3462,6 +3486,9 @@ int btd_adapter_switch_online(struct btd_adapter *adapter) if (adapter->up) return 0; + if (adapter->off_timer) + off_timer_remove(adapter); + return adapter_ops->set_powered(adapter->dev_id, TRUE); } @@ -3473,6 +3500,19 @@ int btd_adapter_switch_offline(struct btd_adapter *adapter) if (!adapter->up) return 0; + if (adapter->off_timer) + return 0; + + if (adapter->connections) { + g_slist_foreach(adapter->connections, + (GFunc) device_request_disconnect, NULL); + + adapter->off_timer = g_timeout_add_seconds(OFF_TIMER, + switch_off_timeout, adapter); + + return 0; + } + return adapter_ops->set_powered(adapter->dev_id, FALSE); } -- 1.6.3.3
