[Bug 1566221] Re: linux: Enforce signed module loading when UEFI secure boot

 

This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
vivid' to 'verification-done-vivid'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Bug description:
  This work is authorized by an approved UOS spec and blueprint at
  https://wiki.ubuntu.com/Spec/InstallingUnsignedSecureBoot

  Add code to implement secure boot checks. Unsigned or incorrectly
  signed modules will continue to install while tainting the kernel
  _until_ EFI_SECURE_BOOT_SIG_ENFORCE is enabled.

  When EFI_SECURE_BOOT_SIG_ENFORCE is enabled, then the only recourse
  for platforms booting in secure boot mode with a DKMS dependency is to
  disable secure boot using mokutil:

  sudo mokutil --disable-validation
  sudo reboot
