radare2-extras

This repository contains extra plugins for radare2.

The reasons why those plugins are distributed in a separate repository are the following:

• Depends on external libraries (yara, ewf)
• Marginal/specific use (ctf-specific asm/anal vm f.ex)
• r2 must be self-contained (no optional/external deps)
• Simplify packagers work, and makes it more flexible
• Duplicates functionality from r2 (no need to have multiple disassemblers for the same arch in core)

The compiled plugins will be installed at

/usr/lib/radare2-extras/$(VERSION)

Some of the plugins/code doesnt compiles, it will be reviewed and cleaned up, merged into core, updated or removed.

In addition, this repository will be useful to new contributors, comers who want to write his own r2 plugins for example.

The aim of this repository is to make the master radare2 repository to be as concise as possible, and reduce the amount of unnecessary plugins to shrink the install size and keep it usable for 99% of users.

Building

To build radare2-extras, just follow the common gnu-configure steps:

./configure --prefix=/usr
make baleful
make baleful-install

To install yara3 and the r2 plugin:

./configure --prefix=/usr
make install-yara3
make yara3
make yara3-install

Note the symstall instead of install will symlink the plugins instead of copying them. This way you can just avoid installing every time you build. This installation method is prefered for developers.

Each module may have it's own configure script, this way packagers can create plugin-specific packages like this:

radare2-extras-yara -> yara plugin

Directories

• yara/yara2 yara/yara3

  yara2/3 command. Depends on libyara

• libr/asm/p

  Contains assembler/disassembler plugins:

  • m68k
  • armthumb
  • psosvm
  • ppc

• libr/bin/p

  Bin-related plugins:

  • dlang demangler

• libr/anal/p

  Contains code analysis plugins

• libr/vm

  Contains the initial implementation of ESIL. It is kept for historical reasons, but will be removed soon or late.

• libr/cmd

  very work-in-progress core cmd plugins for historical reasons, but will be removed soon or late.

RFC

In addition we should add sys/*.sh files to fetch and build the plugins and dependencies if needed (yara.sh) to allow git users to get the proper version installed without depending on the pkgsystem.

We could still provide one-liners to help them. We should keep different versioning numbers for each plugin..

radare2-extras-yara3-0.9.9-0.1
[pkgname] [modname] [r2version] [modversion]

• Do we need a radare2-extra-regressions then?

I would just add the tests inside the radare2-extras/libr/core/p/yara/t/ for example.. and just make those tests run from inside that repo, no need to add more repos because those plugins would be pretty contained.

• What about checking all the tests right away?

Also maybe the plugins depend on some r2 behavior, that has been broken, and we need to test for that jenkins should run those tests don't know much about jenkins, so i won't say much. just hoping it covers all our bases.
