When copying the setup_header into the boot_params buffer, only the data that is actually part of the setup_header should be copied. efi_pe_entry() currently copies the entire second sector, which initializes some of the fields in boot_params beyond the setup_header with garbage (i.e. part of the real-mode boot code gets copied into those fields). This does not cause any issues currently because the fields that are overwritten are padding, BIOS EDD information that won't get used, and the E820 table which will get properly filled in later. Fix this to only copy data that is actually part of the setup_header structure. Signed-off-by: Arvind Sankar <nivedita@alum.mit.edu> Signed-off-by: Ard Biesheuvel <ardb@kernel.org> |
