rng: Introduce SPL_DM_RNG

2024-05-05T14:21:39+00:00

Add SPL variant of DM_RNG so that the DM_RNG can be disabled in SPL
if necessary. This may be necessary due to e.g. size constraints of
the SPL.

efi_selftest: add tests for QueryVariableInfo at boottime

2024-05-01T06:39:18+00:00

Previous patches added QueryVariableInfo at runtime tests and
split a common function that can be used at boottime. Weire it
up and run a similar set of tets. While at it move a test which is
checiking for 0 available storage in the common code

Add tests for
- Test QueryVariableInfo returns EFI_SUCCESS
- Test null pointers for the function arguments
- Test invalid combination of attributes

efi_selftest: add tests for QueryVariableInfo at runtime

2024-05-01T06:39:16+00:00

Since we support QueryVariableInfo at runtime now add the relevant
tests. Since we want those to be reusable at bootime, add them
in a separate file

Add tests for
- Test QueryVariableInfo returns EFI_SUCCESS
- Test null pointers for the function arguments
- Test invalid combination of attributes

efi_loader: enable QueryVariableInfo at runtime for file backed variables

2024-05-01T05:40:05+00:00

Since commit c28d32f946f0 ("efi_loader: conditionally enable SetvariableRT")
we are enabling the last bits of missing runtime services.
Add support for QueryVariableInfo which we already support at boottime
and we just need to mark some fucntions available at runtime and move
some checks around.

It's worth noting that pointer checks for maxmimum and remaining
variable storage aren't when we store variables on the RPMB, since the
Secure World backend is already performing them.

Although it doesn't cause any functional issues, remove the superfluous
checks

efi_loader: do not install dtb if bootmgr fails

If the UEFI boot manager fails there is no point in installing the

efi_loader: improve error handling in try_load_entry()

2024-05-01T05:38:29+00:00

The image is not unloaded if a security violation occurs.

If efi_set_load_options() fails, we do not free the memory allocated for
the optional data. We do not unload the image.

* Unload the image if a security violation occurs.
* Free load_options if efi_set_load_options() fails.
* Unload the image if efi_set_load_options() fails.

efi_loader: superfluous efi_restore_gd after EFI_CALL

2024-05-01T05:37:32+00:00

EFI_CALL() invokes __efi_entry_check() which executes set_gd(efi_gd).
There is no need to execute set_gd(efi_gd) again via efi_restore_gd().
