Return-Path: From: Jakub Pawlowski To: linux-bluetooth@vger.kernel.org Cc: Jakub Pawlowski Subject: [PATCH v6 2/6] Bluetooth: preparation for new connect procedure Date: Wed, 29 Jul 2015 17:17:38 +0200 Message-Id: <1438183062-3265-2-git-send-email-jpawlowski@google.com> In-Reply-To: <1438183062-3265-1-git-send-email-jpawlowski@google.com> References: <1438183062-3265-1-git-send-email-jpawlowski@google.com> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: Currently, when trying to connect to already paired device that just rotated its RPA MAC address, old address would be used and connection would fail. In order to fix that, kernel must scan and receive advertisement with fresh RPA before connecting. This patch adds some fields to hci_conn_params, in preparation to new connect procedure. explicit_connect will be used to override any current auto_connect action, and connect to device when ad is received. HCI_AUTO_CONN_EXPLICIT was added to auto_connect enum. When this value will be used, explicit connect is the only action, and params can be removed after successful connection. HCI_CONN_SCANNING is added to hci_conn flags. When it's set, connect is scan phase. It gets cleared when advertisement is received, and HCI_OP_LE_CREATE_CONN is sent.
