Subject: [PATCH] Bluetooth: Fix rejecting SMP security request in slave role
Date: Tue,  5 Nov 2013 11:30:39 +0200	[thread overview]
Message-ID: <1383643839-2788-1-git-send-email-johan.hedberg@gmail.com> (raw)

From: Johan Hedberg <johan.hedberg@intel.com>

The SMP security request is for a slave role device to request the
master role device to initiate a pairing request. If we receive this
command while we're in the slave role we should reject it appropriately.
