From 6ab0833320c118b6a55f328c5a1b6d35d851decc Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas <javierm@redhat.com> Date: Wed, 24 Feb 2021 22:59:59 +0100 Subject: [PATCH 13/41] commands/setpci: Restrict setpci command when locked down This command can set PCI devices register values, which makes it dangerous in a locked down configuration. Restrict it so can't be used on this setup.
