This is done for moving packages that are related to secure boot
out of LAT and into integ.
Use grub version: 2.06-1 .
Port grub-efi from LAT and make its build independent from grub2.
The patches for code and changes for debian build are ported from
layers ( meta-lat and meta-secure-core ) of yocto upstream.
Make grub-efi independent from grub2 because some code changes
for secure boot can make grub-pc's build fail.
This porting of grub-efi customizes grub images and grub.cfg for
efi boot. Install those files customized to grub-efi-amd64 package.
Test Plan:
The tests are done with all the changes for this porting,
which involves efitools/shim/grub2/grub-efi/lat-sdk.sh, because
they are in a chain for secure boot verification.
- PASS: secure boot OK on qemu.
- PASS: secure boot OK on PowerEdge R430 lab.
- PASS: secure boot NG on qemu/hardware when shim/grub-efi images
are without the right signatures.

Subject: [PATCH] efi: chainloader: take care of unload undershim
|
|
|
|
Upstream-Status: Inappropriate [embedded specific]
|
|
|
|
Under shim, we use a custom buffer to put the relocated image, make
|
|
sure we free that memory when unloading.
