From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Marcel Holtmann To: linux-bluetooth@vger.kernel.org Subject: [PATCH] Bluetooth: Update L2CAP socket source address from HCI connection Date: Sun, 13 Oct 2013 05:56:37 -0700 Message-Id: <1381668997-1240-1-git-send-email-marcel@holtmann.org> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: When having LE connections, the source address is not always the public address of the controller. So update the socket address based on the actual used source address of the HCI connection. This also remove the pointless source address pointer and adds a proper lock around the socket structure.
