From b0916ea0d9e6ea3ed46bb7a61c13a2b357b0248b Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Mon, 10 Jan 2011 13:44:55 +0200 Subject: Bluetooth: Add controller side link key clearing to hci_init_req The controller may have link keys in its own memory and these keys could be used for secure connections. However, since the interface to access these keys doesn't provide information about the key types (which would be needed to infer the level of security each key provides) using these keys is rather useless. Therefore, simply clear the controller side list in the initialization procedure. Signed-off-by: Johan Hedberg Signed-off-by: Gustavo F.
