Subject: [PATCH 04/12] efi: Enable secure boot lockdown automatically when enabled in firmware
Date: Mon, 18 Mar 2013 17:32:25 -0400 [thread overview]
Message-ID: <1363642353-30749-4-git-send-email-matthew.garrett@nebula.com> (raw)
In-Reply-To: <1363642353-30749-1-git-send-email-matthew.garrett@nebula.com>
The firmware has a set of flags that indicate whether secure boot is enabled
and enforcing. Use them to indicate whether the kernel should lock itself
down. We also indicate the machine is in secure boot mode by adding the
EFI_SECURE_BOOT bit for use with efi_enabled.
