From cd4d5671385ba0c6355e013512ea6d06b1ebce02 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann <marcel@holtmann.org> Date: Wed, 23 Jul 2014 21:55:22 +0200 Subject: [PATCH] Bluetooth: Ignore ADV_DIRECT_IND attempts from unknown devices Unconditionally connecting to devices sending ADV_DIRECT_IND when the controller is in CONNECTABLE mode is a feature that is not fully working. The background scanning trigger for this has been removed, but the statement allowing it to happen in case some other part triggers is still present. So remove that code part as well to avoid unwanted connections.
