From 562db3bb3fa16abf6f758e97f9e5496f1c14d423 Mon Sep 17 00:00:00 2001 From: Luigi Semenzato Date: Mon, 13 Jan 2014 17:45:54 -0800 Subject: libpayload: find source of input characters This change makes it possible for vboot to avoid an exploit that could cause involuntary switch to dev mode. It gives depthcharge/vboot some information on the type of input device that generated a key.
