Title:
Linux 4.12 refuses to load self-signed modules under Secure Boot with
properly enrolled keys
Status in linux package in Ubuntu:
In Progress
Bug description:
Since version 4.12, Linux refuses to load my self-signed VirtualBox
modules.
$ lsb_release -d
Description: Ubuntu Artful Aardvark (development branch)
$ uname -rvm
4.12.0-11-generic #12-Ubuntu SMP Fri Aug 11 12:26:42 UTC 2017 x86_64
$ sudo modprobe -v vboxdrv
insmod /lib/modules/4.12.0-11-generic/misc/vboxdrv.ko
modprobe: ERROR: could not insert 'vboxdrv': Required key not available
I've followed [this guide](https://askubuntu.com/a/768310/65926) to import
the key an sign the modules. It worked until kernel 4.11.
The key is properly enrolled:
$ sudo mokutil --test-key .mok/mok-eric-carvalho.der
.mok/mok-eric-carvalho.der is already enrolled
I think this happens because the kernel was built without
CONFIG_MODULE_SIG_UEFI:
$ ls -1 /boot/config-*
/boot/config-4.11.0-13-generic
/boot/config-4.12.0-11-generic
$ grep CONFIG_MODULE_SIG_UEFI /boot/config-*
/boot/config-4.11.0-13-generic:CONFIG_MODULE_SIG_UEFI=y
Same problem with kernel 4.12.0-12.13 from the proposed repository.
