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. Signed-off-by: Masahisa Kojima Swap two ifs in efi_exit_boot_services(). efi_tcg2_notify_exit_boot_services must have EFIAPI signature. Signed-off-by: Heinrich Schuchardt

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.

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: TPL_HIGH_LEVEL not allowed for CreateEvent

2021-06-28T17:57:13+00:00

According to chapter 7.1 "Event, Timer, and Task Priority Services" TPL_HIGH_LEVEL should not be exposed to applications and drivers. According to the discussion with EDK II contributors this implies that CreateEvent() shall not allow to create events with TPL_HIGH_LEVEL.

efi_loader: Clean up file size calculations

2021-03-25T20:03:51+00:00

We recently added a common function for calculating file size, instead of copy pasting the code around. Switch one of the occurences over to the common function Signed-off-by: Ilias Apalodimas Reviwed-by: Heinrich Schuchardt

efi: Add ESRT to the EFI system table

2021-03-25T19:19:19+00:00

The ESRT is initialised during efi_init_objlist after efi_initialize_system_table(). The ESRT is recreated from scratch at the following events: - successful UpdateCapsule; - FMP instance install. The code ensures that every ESRT entry has a unique fw_class value. Limitations: - The ESRT is not updated if an FMP instance is uninstalled; - the fields image_type and flags are in the current implementation left undefined. Setting these values will require a per-platform function that returns the image_type/flags as a function of the image fw_class.

common: Drop asm/global_data.h from common header

2021-02-02T20:33:42+00:00

Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include at all, so remove that include. Signed-off-by: Simon Glass Signed-off-by: Tom Rini

efi_loader: notification with TPL_APPLICATION not allowed

2021-01-23T06:56:54+00:00

The UEFI specification requires event notification levels to be > TPL_APPLICATION and <= TPL_HIGH_LEVEL. With the patch the CreateEvent() and CreatedEventEx() services are changed to check that the notification level is not TPL_APPLICATION.

efi_loader: event queueing

2020-12-31T13:33:32+00:00

When a new event is queued we have to process the event queue by calling efi_process_event_queue(). But there is not reason to call the function when the event is not queueable. Signed-off-by: Heinrich Schuchardt
