grub2 (1.99-21ubuntu3.7) precise-proposed; urgency=low

  * Fix backport mistake that caused grub.cfg not to be created in $efidir
    if UEFI Secure Boot is enabled.
  * When installing to removable media with UEFI Secure Boot, install
    gcdx64.efi.signed rather than grubx64.efi.signed.
  * Make gcdx64.efi.signed fall back to sourcing $prefix/grub.cfg if
    $prefix/x86_64-efi/grub.cfg is missing, as is likely when using
    'grub-install --removable'.

grub2 (1.99-21ubuntu3.6) precise-proposed; urgency=low

  * Fix backport mistake in patch to install signed images if UEFI Secure
    Boot is enabled.

grub2 (1.99-21ubuntu3.5) precise-proposed; urgency=low

  * Backport several changes to support Secure Boot patches.
  * Add Secure Boot patches from Ubuntu 12.10 and Fedora (LP: #1075181):
    - Don't permit loading modules on UEFI secure boot.
    - Add efifwsetup module to reboot into firmware setup menu.
    - Add "linuxefi" loader which avoids ExitBootServices.
    - Only build linuxefi on amd64.
    - Make linuxefi refuse to boot without shim.
    - Make the linux module call linuxefi when necessary, simplifying
    - If secure boot is enabled and the kernel is signed, linux will call
      linuxefi to hand over to it without calling ExitBootServices.
    - Otherwise, linux will fall through to previous code, call
      ExitBootServices itself, and boot the kernel normally.
    - Change linuxefi to return GRUB_ERR_ACCESS_DENIED rather than
      GRUB_ERR_INVALID_COMMAND in the case of an invalid signature, to make
      it easier to implement different handling of unsigned kernels in
      future if necessary.
    - Generate configuration for signed UEFI kernels if available.
    - Install signed images if UEFI Secure Boot is enabled.
    - Output a menu entry for firmware setup on UEFI FastBoot systems.
    - Add some extra debugging to signed/unsigned kernel logic.
    - On amd64, build two images for signing: one with prefix /EFI/BOOT for
      use on removable media, and one with prefix /EFI/ubuntu (and with the
      lvm, mdraid09, and mdraid1x modules added) for use on fixed disks.
