📄 Description
Summary
Callers can now open a headerless executable by supplying the CPU family and the address where file offset 0 is mapped. Header-based detection is unchanged when
formatis omitted. Hopper and IDA refuse this interpretation; Ghidra imports it withBinaryLoaderand a little-endian generic language, then seeds anentryfunction before auto-analysis.Fixes #1836
Demo
Problem and expected behavior
A local image without ELF, Mach-O, PE, or MZ headers is rejected as
truncated or unsupported binary header. Embedded firmware often has those headers removed, so inventory and function analysis cannot start even when the caller already knows the CPU family and load address.format=raw-binarywitharchitecture(x86,x86_64,arm, orarm64) andentry_point(0xhex) admits the complete file as an executable. File offset 0 maps at that address. Architecture or entry withoutformat=raw-binaryis rejected. The analysis profile includes the bound Ghidra language and canonical entry, so a different architecture or entry is a different snapshot identity.Change and scope
