Return-Path: From: Arman Uguray To: linux-bluetooth@vger.kernel.org Cc: Arman Uguray Subject: [PATCH BlueZ 6/7] shared/gatt-db: Fix range handling in read by grp type. Date: Sun, 26 Oct 2014 14:12:46 -0700 Message-Id: <1414357967-9371-7-git-send-email-armansito@chromium.org> In-Reply-To: <1414357967-9371-1-git-send-email-armansito@chromium.org> References: <1414357967-9371-1-git-send-email-armansito@chromium.org> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: This patch fixes bug in gatt_db_read_by_grp_type in which the range end handle was being ignored. This caused incorrect results to be sent for a database where services exists beyond the end handle provided in the request. --- src/shared/gatt-db.c | 11 ++++++++++- 1 file changed, 10 insertions(+), 1 deletion(-) diff --git a/src/shared/gatt-db.c b/src/shared/gatt-db.c index b3f95d2..4e74030 100644 --- a/src/shared/gatt-db.c +++ b/src/shared/gatt-db.c @@ -428,6 +428,7 @@ static void read_by_group_type(void *data, void *user_data) { struct read_by_group_type_data *search_data = user_data; struct gatt_db_service *service = data; + uint16_t grp_start, grp_end; if (!service->active) return; @@ -439,7 +440,15 @@ static void read_by_group_type(void *data, void *user_data) if (bt_uuid_cmp(&search_data->uuid, &service->attributes[0]->uuid)) return; - if (service->attributes[0]->handle < search_data->start_handle) + grp_start = service->attributes[0]->handle; + grp_end = service->attributes[service->num_handles - 1]->handle; + + if (grp_end < search_data->start_handle || + grp_start > search_data->end_handle) + return; + + if (service->attributes[0]->handle < search_data->start_handle || + service->attributes[0]->handle > search_data->end_handle) return; /* Remember size of uuid */ -- 2.1.0.rc2.206.gedb03e5
