This bug tracks progress on the integration work needed. stubble will allow us to load device trees automatically as part of an EFI boot stub on Qualcomm Snapdragon laptops and have them signed/verified with UEFI secure boot. A more detailed explanation for how and why we plan this is available in the form of a spec at https://discourse.ubuntu.com/t/spec-stubble-a-secure-boot-friendly- device-tree-loading-efi-stub/66560 Status ====== [X] Package stubble - https://launchpad.net/ubuntu/+source/stubble (needs another update) [X] MIR - https://bugs.launchpad.net/ubuntu/+source/stubble/+bug/2120322 [X] Get signing request reviewed - https://github.com/rhboot/shim-review/issues/484 [X] Upload latest stubble changes [X] Integrate into kernel build [ ] Drop flash-kernel dependency from ubuntu-x1*-settings [ ] Update debian-cd to remove dtb hacks [ stubble 4-0ubuntu2 FFe - done ] For convenience reasons we would like to add some of the kernel packaging/signing logic in the stubble package instead of putting it into linux-signed directly. This would include a new binary package including a kernel postinst script that builds a stubble bundled kernel. The new package pulled in by linux-signed as a dependency. While we are there I would also like to include a patch to hide a verbose error message in stubble behind the debug flag. The risk of the stubble upload itself should be pretty low since it is a new package that doesn't yet have any reverse dependencies. The planned changes are available in the upstream repo at https://github.com/ubuntu/stubble/tree/ubuntu/main PPA builds will be available in https://launchpad.net/~apw/+archive/ubuntu/signing/+packages where we test the entire kernel build + signing pipeline [ ubuntu-x1*-settings FFe ] Once the kernel has migrated to main, we want to drop the flash-kernel dependency from our ubuntu-x1*-settings packages since that isn't needed anymore. flash-kernel is currently used to install a kernel update hook that will copy the device tree from a freshly installed kernel to /boot where it will be registered by update-grub. With stubble this is not necessary anymore. I have verified that already installed dtbs on /boot do not get deleted by removing flash-kernel, so this won't break currently working pre-stubble kernels that already have a dtb available.
