EFI does -not care about this magic number, and nor should GRUB: this prevents us -from booting other PE linux images, such as the generic EFI zboot -decompressor, which is a pure PE/COFF image, and does not implement the -bare metal boot protocol. - -So drop the magic number check. - -Signed-off-by: Ard Biesheuvel <ardb@kernel.org> -Reviewed-by: Daniel Kiper <daniel.kiper@oracle.com> ---- - grub-core/loader/arm64/linux.c | 3 --- - 1 file changed, 3 deletions(-) - -diff --git a/grub-core/loader/arm64/linux.c b/grub-core/loader/arm64/linux.c -index ef3e9f9..4c92e48 100644 ---- a/grub-core/loader/arm64/linux.c -+++ b/grub-core/loader/arm64/linux.c -@@ -51,9 +51,6 @@ static grub_addr_t initrd_end; - grub_err_t - grub_arch_efi_linux_check_image (struct linux_arch_kernel_header * lh) - { -- if (lh->magic != GRUB_LINUX_ARMXX_MAGIC_SIGNATURE) -- return grub_error(GRUB_ERR_BAD_OS, "invalid magic number"); -- - if ((lh->code0 & 0xffff) != GRUB_PE32_MAGIC) - return grub_error (GRUB_ERR_NOT_IMPLEMENTED_YET, - N_("plain image kernel not supported - rebuild with CONFIG_(U)EFI_STUB enabled")); --- -cgit v1.1 - |
