From b899efaf9b26cadb084752862490b4fc44bc3169 Mon Sep 17 00:00:00 2001 From: Vinicius Costa Gomes Date: Thu, 2 Feb 2012 21:08:00 -0300 Subject: Bluetooth: Add new structures for handling SMP Long Term Keys This includes a new list for storing the keys and a new structure used to represent each key. Some notes: authenticated is used to identify that the key may be used to setup a HIGH security link. As the same list is used to store both the STK's and the LTK's the type field is used so we can separate between those two types of keys and if the key should be used when in the master or slave role.
