From cb92205bad2e4dd630b884142dd707b72504c200 Mon Sep 17 00:00:00 2001 From: Jakub Pawlowski Date: Wed, 5 Aug 2015 23:16:29 +0200 Subject: Bluetooth: fix MGMT_EV_NEW_LONG_TERM_KEY event This patch fixes how MGMT_EV_NEW_LONG_TERM_KEY event is build. Right now val vield is filled with only 1 byte, instead of whole value. This bug was introduced in commit 1fc62c526a57 ("Bluetooth: Fix exposing full value of shortened LTKs") Before that patch, if you paired with device using bluetoothd using simple pairing, and then restarted bluetoothd, you would be able to re-connect, but device would fail to establish encryption and would terminate connection. After this patch connecting after bluetoothd restart works fine.
