From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Johan Hedberg To: linux-bluetooth@vger.kernel.org Subject: [PATCH 1/2] Bluetooth: Fix link security setting when powering on Date: Sat, 26 Jan 2013 16:33:49 -0600 Message-Id: <1359239630-3579-1-git-send-email-johan.hedberg@gmail.com> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: From: Johan Hedberg If a controller is powered on while the HCI_AUTO_OFF flag is set the link security setting (HCI_LINK_SECURITY) might not be in sync with the actual state of the controller (HCI_AUTH). This patch fixes the issue by checking for inequality between the intended and actual settings and sends a HCI_Write_Auth_Enable command if necessary.
