From cc2b6911a205b327b29c1d771925f8ab2f80295f Mon Sep 17 00:00:00 2001 From: Jakub Pawlowski Date: Fri, 7 Aug 2015 20:22:55 +0200 Subject: Bluetooth: timeout handling in new connect procedure Currently, when trying to connect to already paired device that just rotated its RPA MAC address, old address would be used and connection would fail. In order to fix that, kernel must scan and receive advertisement with fresh RPA before connecting. This patch makes sure that when new procedure is in use, and we're stuck in scan phase because no advertisement was received and timeout happened, or app decided to close socket, scan whitelist gets properly cleaned up.
