Pull request for UEFI sub-system for efi-2020-10-rc1 (3)
Up to now UEFI variables where stored in U-Boot environment variables.
Saving UEFI variables was not possible without saving the U-Boot
environment variables. With this patch series file ubootefi.var in the
EFI system partition is used for saving UEFI variables. Furthermore the
UEFI variables are exposed for reading at runtime.
Code corrections for UEFI secure boot are provided.
A buffer overrun in the RSA library is fixed.
There are two options that are currently whitelisted, but they
are redundant, because there are not necessary since Kconfig options
exist to basically state the same thing.
CONFIG_DIRECT_NOR_BOOT and CONFIG_USE_NOR are both set together and
only used by the da850 when booting from NOR, however the only time
CONFIG_MTD_NOR_FLASH is configured is when booting from NOR. Since
NOR doesn't need SPL, the options for SPL can be moved to a check for
building SPL instead of checking for NOR.
This patch removes the checks for these two config options and unifies
the checks around the Kconfig option of CONFIG_MTD_NOR_FLASH.
Since this board is the only board that uses these two config options,
they can be removed from the whitelist table.

In case that a type of certificate in "db" or "dbx" is
EFI_CERT_X509_SHA256_GUID, it is actually not a certificate which contains
a public key for RSA decryption, but a digest of image to be loaded.
If the value matches to a value calculated from a given binary image, it is
granted for loading.
With this patch, common digest check code, which used to be used for
unsigned image verification, will be extracted from
efi_signature_verify_with_sigdb() into efi_signature_lookup_digest(), and
extra step for digest check will be added to efi_image_authenticate().
Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org>
A signed image may have multiple signatures in
- each WIN_CERTIFICATE in authenticode, and/or
- each SignerInfo in pkcs7 SignedData (of WIN_CERTIFICATE)
In the initial implementation of efi_image_authenticate(), the criteria
of verification check for multiple signatures case is a bit ambiguous
and it may cause inconsistent result.
With this patch, we will make sure that verification check in
efi_image_authenticate() should pass against all the signatures.
The only exception would be
- the case where a digest algorithm used in signature is not supported by
U-Boot, or
- the case where parsing some portion of authenticode has failed
In those cases, we don't know how the signature be handled and should
just ignore them.
Please note that, due to this change, efi_signature_verify_with_sigdb()'s
function prototype will be modified, taking "dbx" as well as "db"
instead of outputing a "certificate." If "dbx" is null, the behavior would
be the exact same as before.
The function's name will be changed to efi_signature_verify() once
current efi_signature_verify() has gone due to further improvement
in intermediate certificates support.

I increased the maximum U-Boot proper size from time to time, but
configs/uniphier_v7_defconfig hit the current limit 832KB.
Some historical info:
In the initial support, the max size was 512MB.
Commit 58d702274c ("ARM: uniphier: increase CONFIG_SYS_MONITOR_LEN")
increased it to 576KB, and commit 3ce5b1a8d8 ("ARM: uniphier: move
SPL stack address") moved the SPL stack location to avoid the memory
map conflict. It was the solution to increase the size without changing
the NOR boot image map.
commit 1a4bd3a095 ("ARM: uniphier: increase CONFIG_SYS_MONITOR_LEN
again") ended up with increasing the max size again, breaking the NOR
boot image map. The limit was set to 832KB, otherwise the SPL stack
would overwrite the U-Boot proper image:
CONFIG_SPL_STACK - CONFIG_SYS_UBOOT_BASE + sizeof(struct image_header) = 0xd0000
To increase CONFIG_SYS_MONITOR_LEN even more, the SPL stack must be
moved somewhere. I put it back to the original location prior to
commit 3ce5b1a8d8.
With this change, there is no more practical size limit.
