efi_loader: Fix buffer underflow

2022-11-22T10:54:30+00:00

If the array index 'i' < 128, the 'codepage' array is accessed using
[-128...-1] in efi_unicode_collation.c:262. This can lead to a buffer
overflow.

    Negative index in efi_unicode_collation.c:262.

The index of the 'codepage' array should be c - 0x80 instead of i - 0x80.

efi_loader: remove EFI_UNICODE_COLLATION_PROTOCOL

2021-01-20T07:17:17+00:00

In EFI 1.10 a version of the Unicode collation protocol using ISO 639-2
language codes existed. This protocol is not part of the UEFI specification
any longer. It was however required to run the UEFI Self Certification Test
(SCT) II, version 2.6, 2017. So we implemented it for the sole purpose of
running the SCT.

As the SCT does not need the protocol anymore it is time for removal.
