From 271e0c9dce1b02a825b3cc1a7aa1fab7c381d44b Mon Sep 17 00:00:00 2001 From: Libo Chen Date: Fri, 20 Nov 2020 18:12:43 -0800 Subject: [PATCH] ktest.pl: Fix incorrect reboot for grub2bls This issue was first noticed when I was testing different kernels on Oracle Linux 8 which as Fedora 30+ adopts BLS as default. Even though a kernel entry was added successfully and the index of that kernel entry was retrieved correctly, ktest still wouldn't reboot the system into user-specified kernel. The bug was spotted in subroutine reboot_to where the if-statement never checks for REBOOT_TYPE "grub2bls", therefore the desired entry will not be set for the next boot. Add a check for "grub2bls" so that $grub_reboot $grub_number can be run before a reboot if REBOOT_TYPE is "grub2bls" then we can boot to the correct kernel.
