Return-Path: From: Arman Uguray To: linux-bluetooth@vger.kernel.org Cc: Arman Uguray Subject: [PATCH BlueZ v3 7/8] core: gatt: Use "claimed" instead of "active" Date: Tue, 13 Jan 2015 19:31:06 -0800 Message-Id: <1421206267-26369-8-git-send-email-armansito@chromium.org> In-Reply-To: <1421206267-26369-1-git-send-email-armansito@chromium.org> References: <1421206267-26369-1-git-send-email-armansito@chromium.org> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: Using the "active" state of a gatt-db service to mark a service as claimed by a profile somewhat abuses the API and has the additional side-effect of sending a service_removed event. This causes errors in the way btd_device manages profile/service lifetime. To fix this, this patch uses the new "claimed" state to mark a service as claimed. Also included is a minor fix to btd_gatt_client_* APIs that early return if the client is not yet ready. --- src/device.c | 7 +++++-- src/gatt-client.c | 9 ++++++--- 2 files changed, 11 insertions(+), 5 deletions(-) diff --git a/src/device.c b/src/device.c index 9d1a480..1253986 100644 --- a/src/device.c +++ b/src/device.c @@ -2566,7 +2566,7 @@ static void dev_probe_gatt(struct btd_profile *p, void *user_data) } /* Mark service as claimed */ - gatt_db_service_set_active(data->cur_attr, false); + gatt_db_service_set_claimed(data->cur_attr, true); data->dev->services = g_slist_append(data->dev->services, service); } @@ -2603,8 +2603,11 @@ static void dev_probe_gatt_profile(struct gatt_db_attribute *attr, } /* Don't probe the profiles if a matching service already exists. */ - if (find_service_with_uuid(data->dev->services, data->cur_uuid)) + if (find_service_with_uuid(data->dev->services, data->cur_uuid)) { + /* Mark the service as claimed by the existing profile. */ + gatt_db_service_set_claimed(data->cur_attr, true); return; + } btd_profile_foreach(dev_probe_gatt, data); diff --git a/src/gatt-client.c b/src/gatt-client.c index a12c656..cb8ddf6 100644 --- a/src/gatt-client.c +++ b/src/gatt-client.c @@ -52,6 +52,7 @@ struct btd_gatt_client { struct btd_device *device; + bool ready; char devaddr[18]; struct gatt_db *db; struct bt_gatt_client *gatt; @@ -1373,7 +1374,7 @@ static void export_service(struct gatt_db_attribute *attr, void *user_data) struct btd_gatt_client *client = user_data; struct service *service; - if (!gatt_db_service_get_active(attr)) + if (gatt_db_service_get_claimed(attr)) return; service = service_create(attr, client); @@ -1461,13 +1462,15 @@ void btd_gatt_client_ready(struct btd_gatt_client *client) bt_gatt_client_unref(client->gatt); client->gatt = bt_gatt_client_ref(gatt); + client->ready = true; + create_services(client); } void btd_gatt_client_service_added(struct btd_gatt_client *client, struct gatt_db_attribute *attrib) { - if (!client) + if (!client || !attrib || !client->ready) return; export_service(attrib, client); @@ -1486,7 +1489,7 @@ void btd_gatt_client_service_removed(struct btd_gatt_client *client, { uint16_t start_handle, end_handle; - if (!client || !attrib) + if (!client || !attrib || !client->ready) return; gatt_db_attribute_get_service_handles(attrib, &start_handle, -- 2.2.0.rc0.207.ga3a616c
