From a82505c7bcbc1f8cce28d092aba01f62c7b85fa3 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Mon, 24 Mar 2014 14:39:07 +0200 Subject: [PATCH] Bluetooth: Don't try to confirm locally initiated SMP pairing In the case that the just-works model would be triggered we only want to confirm remotely initiated pairings (i.e. those triggered by a Security Request or Pairing Request). This patch adds the necessary check to the tk_request function to fall back to the JUST_WORKS method in the case of a locally initiated pairing.
