Hi! This is v2 of [1]
Changes since v2: - Lengths checks when interpreting a device path, to make sure we aren't going out of bounds - renamed efi_get_file_size -> efi_file size and moved it itn efi_file.c - Fix uninitialized variable related errors reported by Cppcheck - Fixed various error messages for easier end user readbility - renamed _efi_dp_append() -> efi_dp_append_or_concatenate() - Picked up Reviewed-by tags - Enabling the protocol by default
Changes since v1: - minor coding style fixes from Heinrich - changed the DP format. Instead of VenMedia - 0x01 - initrd, we skip the 0x01 between VenMedia and the first file. - final device path is stripped in efi_get_dp_from_boot() instead of get_initrd_fp() - Fixed comments on documentation
