It has been expanded to not only include dbx entries but also entries in the mokx. Additionally Eric included his patches to preload these certificate [3]. The patches can be found on the following branch: https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git/log/?h=keys-cve-2020-26541-branch Changes: ver #3: - Rolled in changes from Eric to fix conditional building issues[7]. ver #2: - Rolled in a fix to the second patch to include certs/common.h in certs/common.c[6]. ver #1: - I've modified the first patch in the series to fix a configuration problem[4][5], to move the added functions to a more logical place within thefile and to add kerneldoc comments.
