Currently the patchset consists of:
- Reworked Fedora NX patches to make GRUB itself work under NX.
- Julian Andres Klode's loader framework patch (used in Debian and Ubuntu for
the downstream loader).
- Implemented shim loader protocol support using the above loader framework.
- Added patch to disallow using the legacy Linux loader when NX is required.
Future work:
- Implement NX in non-Linux loaders where applicable.
(Note that this is non-crtitical for security, as non-UEFI/Linux loaders are
disabled
by SB lockdown, but would be nice to avoid crashes for unsuspecting users on
future
hardware).
Julian Andres Klode (1):
efi: Provide wrappers for load_image, start_image, unload_image
Mate Kukri (6):
modules: load module sections at page-aligned addresses
nx: add memory attribute get/set API
nx: set page permissions for loaded modules.
nx: set the nx compatible flag in EFI grub images
efi: Use shim's loader protocol for EFI image verification and loading
efi: Disallow fallback to legacy Linux loader when shim says NX is
required.
Peter Jones (3):
modules: make .module_license read-only
modules: strip .llvm_addrsig sections and similar.
modules: Don't allocate space for non-allocable sections.
