From 662e8820f38dcc458e0d4769194db5ed3469224f Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Sun, 13 Oct 2013 05:23:59 -0700 Subject: [PATCH] Bluetooth: Store source address of HCI connections The source addressed was based on the public address of the HCI device, but with LE connections this not always the case. For example single mode LE-only controllers would use a static random address. And this address is configured by userspace. To not complicate the lookup of what kind of address is in use, store the correct source address for each HCI connection.
