efi_loader: use correct type for AllocatePages, AllocatePool

2021-08-17T15:24:08+00:00

Use enum efi_memory_type and enum_allocate_type in the definitions of the
efi_allocate_pages(), efi_allocate_pool().

In the external UEFI API leave the type as int as the UEFI specification
explicitely requires that enums use a 32bit type.

efi_loader: add ExitBootServices() measurement

2021-08-14T18:54:41+00:00

TCG PC Client PFP spec requires to measure
"Exit Boot Services Invocation" if ExitBootServices() is invoked.
Depending upon the return code from the ExitBootServices() call,
"Exit Boot Services Returned with Success" or "Exit Boot Services
Returned with Failure" is also measured.

Swap two ifs in efi_exit_boot_services().
efi_tcg2_notify_exit_boot_services must have EFIAPI signature.

efi_loader: add boot variable measurement

2021-08-14T18:54:41+00:00

TCG PC Client PFP spec requires to measure "Boot####"
and "BootOrder" variables, EV_SEPARATOR event prior
to the Ready to Boot invocation.
Since u-boot does not implement Ready to Boot event,
these measurements are performed when efi_start_image() is called.

TCG spec also requires to measure "Calling EFI Application from
Boot Option" for each boot attempt, and "Returning from EFI
Application from Boot Option" if a boot device returns control
back to the Boot Manager.

Allow efi_loader header to be included always

2021-07-28T18:27:54+00:00

It is bad practice to put function declarations behind an #ifdef since
it makes it impossible to use IS_ENABLED() in the C code. The main reason
for doing this is when an empty static inline function is desired when
the feature is disabled.

To this end, this header provides two different versions of various
functions and macros. Collect them together in one place for clarity.
Allow all the rest of the header to be included, regardless of the
setting of EFI_LOADER.

With the inclusion of blk.h the 'struct blk_desc' declaration is
unnecessary. Drop it while we are here.

efi_loader: remove asm/setjmp.h from efi_api.h

2021-07-24T08:49:51+00:00

In the commit c982874e930d ("efi_loader: refactor
efi_setup_loaded_image()"), setjmp-related definitions were moved to
efi_loaded_image_obj in efi_loader.h. So setjmp.h is no longer
refererenced in efi_api.h.

This also fixes some error when efi_api.h will be included in
mkeficapsule.c.

efi_loader: Always install FMPs

2021-07-02T07:37:01+00:00

We only install FMPs if a CapsuleUpdate is requested.  Since we now have an
ESRT table which relies on FMPs to build the required information, it
makes more sense to unconditionally install them. This will allow userspace
applications (e.g fwupd) to make use of the ERST and provide us with files
we can use to run CapsuleUpdate on-disk

efi_loader: add PE/COFF image measurement

2021-05-28T14:17:01+00:00

"TCG PC Client Platform Firmware Profile Specification"
requires to measure every attempt to load and execute
a OS Loader(a UEFI application) into PCR[4].
This commit adds the PE/COFF image measurement, extends PCR,
and appends measurement into Event Log.

efi_loader: fix warning when linking with LTO
