From f68a6d583578799ec2011476ebd1e10590c6eb3c Mon Sep 17 00:00:00 2001 From: AKASHI Takahiro Date: Thu, 13 Aug 2020 17:05:29 +0900 Subject: [PATCH] efi_loader: variable: fix secure state initialization Under the new file-based variable implementation, the secure state is always and falsely set to 0 (hence, the secure boot gets disabled) after the reboot even if PK (and other signature database) has already been enrolled in the previous boot. This is because the secure state is set up *before* loading non-volatile variables' values from saved data. This patch fixes the order of variable initialization and secure state initialization.
