Radare2 RSoC 2017 Introduction Project Ideas Micro Tasks


The radare project started in February of 2006 aiming to provide a free and simple command line interface for an hexadecimal editor supporting 64 bit offsets to make searches and recovering data from hard-disks. Since then, the project has grown with the aim changed to provide a complete framework for analyzing binaries with some basic *NIX concepts in mind like everything is a file, small programs that interact together using stdin/out, and keep it simple. Radare2 is a complete LGPL rewrite of the original project, to remove design issues of the first iteration, and to make it more modular and easier to script and maintain. It features a testsuite that aims to cover as much cases as possible in order to catch regressions.

Radare2 is composed of an hexadecimal editor as central point, with several assemblers/disassemblers, code analysis capabilities, scripting features, visualization of code and data through graphs and other means, a visual mode, easy unix integration, a diff engine, a shellcode compiler, and much more.


Previous Years

In Summer of 2014, 2015 and 2016, we hosted our own version of Radare Summer of Code (RSoC). These were some of the successful projects:

We were also accepted for Google Summer of Code (GSoC) 2015 under the umbrella of Openwall project and later in 2016 and 2017 as an independent organisation too. Previosly our students finished developing a major part of decompiler (radeco) with radare2 integration (except pseudo-C code emitter). More information is available in the project repository and GSoC’15 pages: project1, project2. This year GSoC students working on improving Windows platform support, implementing timeless debugging capabilities and GDB server, along with improving current GDB client feature.

If you have questions or comments, visit our IRC channel #radare on Freenode.



Members of radare2 core team have volunteered to guide students for RSoC’16. They were already guiding the students for GSoC’15 (under Openwall umbrella), RSoC’15 and RSoC’14 and continuing to guide during the GSoC'16 as well. Please feel free to reach out to any of them in case you need any help in selecting a project.

Development methodology

Currently, all repositories are hosted on github and bugs are tracked on github issues. We are mostly using HackMD, IRC and Telegram for communication. We have a testsuite (that is running on Travis CI, AppVeyor and our Jenkins instance) to test and verify that all the features are still working and that a merge or a commit don't break anything, and to find regressions. We encourage contributors to write test cases and documentation in order to verify the implementation and ensure that everything fits well together. There is also a Coverity instance to catch obvious defects. For the complex bugs and examples we're using our own asciinema installation


Radare2 is modular: this means that it aims to make all the elements and features easily reusable from other projects. The choice of LGPL3 as a license is the minimum requirement to get code merged in r2. Contributors can choose Apache, BSD, MIT, Public Domain, or other similar licenses. The reason to exclude GPL as a valid license for the project is because we aim to support proprietary software that uses r2, while protecting our free codebase.

Instructions for students

It is almost a requirement that students who want to apply to the radare2 project for the Radare Summer of Code 2017 should submit a small pull request accomplishing one of the microtasks as part of their application. Though you can also choose any of the Github issues for radare2 if they are big enough to be a qualification task, still small enough to be finished no more than in a couple of weeks.


Programming languages

Most of radare2 is written in C and hence we expect students to be familiar with C programming language. For the radeco-related tasks, student should know Rust or be willing to learn the same.


Recommended steps

  1. Grab any of the project from list of ideas that you're interested in (or propose your own).
  2. Write a first draft proposal using Google Docs and our template and ask one of the mentors or administrators to review it with you.
  3. Fix a few bugs and send Pull Requests and link them in your proposal.
  4. Submit it to rsoc@radare.org.

Student proposal guidelines

  1. Keep it simple enough to fit not more than a couple of pages. Despite the shortness of the sentences, try to save the clarity of the proposal.
  2. Try to split RSoC period into tasks, and the task into subtasks. It really helps us to understand how you want to accomplish your goals, but even more it'll help you - to understand the task deep enough before starting it, and prioritize important things to do first.
  3. Please, note, how much time a day/week you are going to spend on this project.
  4. Specify your timezone, since so we can assign you a mentor in the same one, to ease communication.
  5. Submit your proposal early, not in the last minute
  6. You can also choose a “backup” idea (the second task you probably want to do), so that in case of some conflicts (two students for one task) it will be easier to solve.
