- ship a Secure Boot UEFI compatible bootloader (fate#314485)
- added secureboot patches which introduces new linuxefi module
  that is able to perform verifying signed images via exported
  protocol from shim. The insmod command will not function if
  secure boot enabled (as all modules should built in grub.efi
  and signed).
  - grub2-secureboot-add-linuxefi.patch
  - grub2-secureboot-use-linuxefi-on-uefi.patch
  - grub2-secureboot-no-insmod-on-sb.patch
  - grub2-secureboot-provide-linuxefi-config.patch
- Makefile.core.am : support building linuxefi module
- Make grub.efi image that is with all relevant modules incorporated
  and signed, it will be the second stage to the shim loader which
  will verified it when secureboot enabled.
- Make grub.efi's path to align with shim loader's default loader
  lookup path.
- The changes has been verified not affecting any factory instalation,
  but will allow us to run & test secure boot setup manually with shim. (forwarded request 143007 from michael-chang)

Subject: [PATCH] provide option in config to enable linuxefi
References: fate#314485
Patch-Mainline: no
As linuxefi module requires kernel 3.6 or later which supports EFI
handover protocol, it may not be able to load kernels without that
supports in place.
In case that things would break, and the linuxefi is really too young to
take over the position of "linux" kernel loader module, we introduce a
option GRUB_USE_LINUXEFI in the config and only explicit set it to true
will enable it. Example usage is
GRUB_USE_LINUXEFI=true grub2-mkconfig -o /boot/efi/EFI/opensuse/grub.cfg
This will output a grub.cfg which uses linuxefi in replace of linux and
enable verification of kernel signature if in secureboot enabled and
has shim exported protocols available.

- ship a Secure Boot UEFI compatible bootloader (fate#314485)
- added secureboot patches which introduces new linuxefi module
that is able to perform verifying signed images via exported
protocol from shim. The insmod command will not function if
secure boot enabled (as all modules should built in grub.efi
and signed).
- grub2-secureboot-add-linuxefi.patch
- grub2-secureboot-use-linuxefi-on-uefi.patch
- grub2-secureboot-no-insmod-on-sb.patch
- grub2-secureboot-provide-linuxefi-config.patch
- Makefile.core.am : support building linuxefi module
- Make grub.efi image that is with all relevant modules incorporated
and signed, it will be the second stage to the shim loader which
will verified it when secureboot enabled.
- Make grub.efi's path to align with shim loader's default loader
lookup path.
- The changes has been verified not affecting any factory instalation,
but will allow us to run & test secure boot setup manually with shim.
-------------------------------------------------------------------
Thu Nov 22 07:01:31 UTC 2012 - mchang@suse.com
- ship a Secure Boot UEFI compatible bootloader (fate#314485)
- In SLE-11 SP3, don't include any other architecture binaries
except EFI, so we split packages by architecture binaries to
meet the requirement.
- grub2 : common utilties and config etc
- grub2-efi : provide compatibilty to grub2-efi package
- grub2-i386-pc : binaries for x86 legacy pc firmware
- grub2-i386-efi : binaries for ia32 EFI firmware
- grub2-x86_64-efi : binaries for x86_64 firmware
- grub2-powerpc-ieee1275: binaries for powerpc open firmware
