From 37e97b4ef0d18b77a45a4714154daf3499206654 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Thu, 28 Sep 2006 15:29:09 -0700 Subject: [PATCH] [Bluetooth]: Don't update disconnect timer for incoming connections In the case of device pairing the only safe method is to establish a low-level ACL link. In this case, the remote side should not use the disconnect timer to give the other side the chance to enter the PIN code. If the disconnect timer is used, the connection will be dropped to soon, because it is impossible to identify an actual user of this link. Signed-off-by: Marcel Holtmann Signed-off-by: David S.
