goblin 0.0.24 releases: cross-platform binary parsing crate, written in Rust
libgoblin is a cross-platform trifecta of binary parsing and loading fun. It supports:
- An ELF32/64 parser, and raw C structs
- A 32/64-bit, zero-copy, endian aware, Mach-o parser, and raw C structs
- A PE32/PE32+ (64-bit) parser, and raw C structs
- A Unix archive parser and loader
Goblin requires at least rustc 1.31.1, uses the 2018 rust edition and is developed on stable.
Goblin primarily supports the following important use cases:
- Core, std-free #[repr(C)] structs, tiny compile time, 32/64 (or both) at your leisure
- Type punning. Define a function once on a type, but have it work on 32 or 64-bit variants – without really changing anything, and no macros! See examples/automagic.rs for a basic example.
- std mode. This throws in read and write impls via Pread and Pwrite, reading from file, convenience allocations, extra methods, etc. This is for clients who can allocate and want to read binaries off the disk.
- Endian_fd. A truly terrible name :laughing: this is for binary analysis like in panopticon which needs to read binaries of foreign endianness, or as a basis for constructing cross-platform foreign architecture binutils, e.g. cargo-sym and bingrep are simple examples of this, but the sky is the limit.
libgoblin is engineered to be tailored towards very different use-case scenarios, for example:
- a no-std mode; just simply set default features to false
- a endian aware parsing and reading
- for binary loaders which don’t require this, simply use elf32 and elf64 (and std of course)
For example, if you are writing a 64-bit kernel, or just want a barebones C-like header interface which defines the structures, just select elf64, –cfg feature=\”elf64\”, which will compile without std.
Similarly, if you want to use host endianness loading via the various from_fd methods, –cfg feature=\”std\”, which will not use the byteorder extern crate, and read the bytes from disk in the endianness of the host machine.
If you want endian aware reading, and you don’t use default, then you need to opt-in as normal via endian_fd
|archive||Implements a simple parser and extractor for a Unix Archive.|
|container||Binary container size information and byte-order context|
|elf||The generic ELF module, which gives access to ELF constants and other helper functions, which are independent of ELF bithood. Also defines an |
|elf32||The ELF 32-bit struct definitions and associated values, re-exported for easy “type-punning”|
|elf64||The ELF 64-bit struct definitions and associated values, re-exported for easy “type-punning”|

- archive: new public enum type to determine which kind of archive was parsed
- archive: thanks @raindev
