From f0ff92fbfa14c1cf8c0346f1dde9c3eda26d5abf Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Sun, 27 Jan 2013 08:32:00 -0600 Subject: Bluetooth: Fix link security setting when powering on 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.
