Without the patch: ----------------------------------------------------------------------- Failed to open \EFI\BOOT\mmx64.efi - Not Found Failed to load image 貘給: Not Found ----------------------------------------------------------------------- With the patch: ----------------------------------------------------------------------- Failed to open \EFI\BOOT\mmx64.efi - Not Found Failed to load image \EFI\BOOT\mmx64.efi: Not Found ----------------------------------------------------------------------- Signed-off-by: Renaud Métrich <[email protected]>
We need to use is_removable_media_path(), and potentially other helpers, from Mok as well as shim. This moves it to a file just for Device Path utility functions to make that simpler. Signed-off-by: Peter Jones <[email protected]>
If MokManager has to be entered but system is booting on disk on EFI/BOOT/BOOTx.EFI entry, MokManager cannot be found because it's not in that directory. This indicates an issue with the BootOrder or the UEFI firmware is just not taking BootOrder into account (seen on Lenovo ThinkPad P1 Gen 6 and VMWare), or that the boot media has incorrectly been created without MokManager. This patch prints a related message and reboots after 10 seconds. Reproducer: 1. Import a certificate using mokutil 2. Tell UEFI to boot on BOOTX64.EFI entry on next boot Result without the patch with verbosity: ----------------------------------------------------------------------- mok.c:1045:import_mok_state() checking mok request shim.c:866:load_image() attempting to load \EFI\BOOT\mmx64.efi Failed to open \EFI\BOOT\mmx64.efi - Not Found Failed to load image \EFI\BOOT\mmx64.efi: Not Found shim.c:888 load_image() Failed to open \EFI\BOOT\mmx64.efi - Not Found shim.c:1115 read_image() Failed to load image \EFI\BOOT\mmx64.efi: Not Found Failed to start MokManager: Not Found mok.c:1047:import_mok_state() mok returned Not Found Something has gone seriously wrong: import_mok_state() failed: Not Found ----------------------------------------------------------------------- Signed-off-by: Renaud Métrich <[email protected]>

Reproducer
Result without the patch (with verbosity enabled)
Result with the patch
Box with title "Could not find MokManager" and message "Boot Order must be misconfigured or not honored by the UEFI firmware.", then system rebooted after 10 seconds (in hope the BootOrder will be good next time).
