From 44b20d33962a73ca14b934540e9168e0da1b49ab Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Sun, 20 Jan 2013 14:27:17 +0200 Subject: [PATCH] Bluetooth: Check for valid key->authenticated value for LTKs This patch adds necessary checks for the two allowed values of the authenticated parameter of each Long Term Key, i.e. 0x00 and 0x01. If any other value is encountered the valid response is to return invalid params to user space.
