Subject: [patch 06/26] setkeys needs root
Date: Tue, 13 Dec 2005 00:22:29 -0800 [thread overview]
Message-ID: <20051213082229.GG5823@kroah.com> (raw)

-stable review patch. If anyone has any objections, please let us know.
------------------
From: Daniel Drake <dsd@gentoo.org>
This patch combines commit 0b360adbdb54d5b98b78d57ba0916bc4b8871968 (make
setkeys root-only) and commit e3f17f0f6e98f58edb13cb38810d93e6d4808e68 (only
disallow setting by users)
Because people can play games reprogramming keys and leaving traps for the
next user of the console.
