This is a note to let you know that I've just added the patch titled ktest.pl: Avoid false positives with grub2 skip regex to the 6.6-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: ktest.pl-avoid-false-positives-with-grub2-skip-regex.patch and it can be found in the queue-6.6 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit a7dec61097d33fbeb303097cbe8fc7eb46649f77 Author: Daniel Jordan <daniel.m.jordan@xxxxxxxxxx> Date: Wed Sep 4 13:55:30 2024 -0400 ktest.pl: Avoid false positives with grub2 skip regex [ Upstream commit 2351e8c65404aabc433300b6bf90c7a37e8bbc4d ] Some distros have grub2 config files with the lines if [ x"${feature_menuentry_id}" = xy ]; then menuentry_id_option="--id" else menuentry_id_option="" fi which match the skip regex defined for grub2 in get_grub_index(): $skip = '^\s*menuentry'; These false positives cause the grub number to be higher than it should be, and the wrong kernel can end up booting. Grub documents the menuentry command with whitespace between it and the title, so make the skip regex reflect this.
