Outreachy (formerly FOSS Outreach Program for Women (OPW) and Project Ascend Alumni)

Please see the Outreachy homepage for an introduction to the program.

The application period for Round 14 will start on February 16, 2016. It's too early to send patches to the outreachy kernel mailing list, but please consider working through the other parts of the tutorial if you are interested in applying.

We are looking for round 14 funding sponsors and Linux kernel mentors. Please see the linked FAQ pages if you want to help out.

Welcome Outreachy applicants! Our round 14 sponsors have generiously donated funds for internships for women, genderqueer, genderfluid, or genderfree people, and residents and nationals of the United States of any gender who are Black/African American, Hispanic/Latino, American Indian, Alaska Native, Native Hawaiian, or Pacific Islander to work on the Linux kernel. The kernel is the most basic layer of the Linux operating system. It encompasses many things: hardware drivers, filesystems, security, task scheduling, and much more.

News This year, we ask that you send all patches to the appropriate staging driver maintainers, as well as to the outreachy mailing list. See Submit a patch for more information. For IIO patches, be sure to send them to

How to apply

The application period for Outreachy Round 14 is February 16 to March 30. Please fill your application by March 30, and complete your kernel patch by March 30 also (7pm UTC in both cases). Applicants that do not complete the first patch will not be considered for an internship. Please take a look at our application FAQ for more info on how to fill out your application.

Participating Linux kernel projects

Applicants for all projects should have basic experience with C or C++ and boolean algebra. Optionally, we would love it if you have basic operating system knowledge, know your way around a Linux/UNIX command line, and/or know the revision system called git. Please note that these three skills can be learned during the internship.

Some projects may have small tasks you can complete as part of the application process. Do not start on these tasks until after you complete the first patch tutorial and Greg Kroah-Hartman has accepted at least ten of your cleanup patches and two of your patchsets. In order to ensure applicants aren't working on the same task, we need your help in coordinating who is working on what task. Please see the Outreachy tasks page for details before starting on a task!

Round 14 projects

Previous projects, from round 13 projects are available here. For each project, if you click on the proposer's name, you may find more information.


Mentor:: Julia Lawall

There will be no Coccinelle project in this round. Please feel free nevertheless to use Coccinelle in making cleanup patches.

Using an IDR to replace the process ID allocator

Mentor:: Matthew Wilcox

Process IDs are currently allocated using a custom allocator. This project would try to replace that allocator with the IDR.


Mentor:: Pablo Neira Ayuso

nftables provides a replacement for the very popular {ip,ip6,arp,eb}tables tools. nftables reuses most of the Netfilter components such as the existing hooks, connection tracking system, NAT, userspace queueing, logging among many other features. So we have only replaced the packet classification framework. nftables comes with a new userspace utility nft and the low-level userspace library libnftnl. The goal will be to help finish the translation layer software that converts from the iptables syntax to nftables, complete some simple missing features and fixing bugs whenever possible.

If you are interested in this project please consider solving any of the following tasks:

  • Request an account for the page and help us improve the content.

  • Provide an iptables to nft translation via the iptables-translate utility. You can give a try to the following extensions: icmp, icmp6, rt.

  • Try to fix any of the existing nft bugs in

For more information on nftables, please check:

IIO driver

Mentors:: Daniel Baluta & Alison Schofield

A driver allows applications to communicate and control hardware devices. Each development cycle, driver changes account for more than a half of the total Linux kernel code changes.

The goal of this project is to write a driver for a sensor using the Industrial I/O interface. In the first part of the project you will get familiar with the hardware and the IIO subsystem then implement raw readings from the device. After upstreaming the code you will enhance the driver with advanced features such as support for buffered readings, power management and interrupts. The exact device will be decided when the internship starts.

We will provide you the hardware setup necessary to test the driver. If you are interested in this project please solve IIO tasks.

For IIO patches, be sure to send them to


Mentor:: Jonathan Corbet

After many years of relative neglect, we are working to improve the kernel's documentation; this includes a transition to the Sphinx formatting system. There are a number of potential projects associated with this transition, ranging from the conversion of existing documents into the ReStructured Text format and integrating them into the manual through to improving the Python/Perl-based document build system, adding kerneldoc comments to the source, and writing entirely new documents.

If you want to work in this area, there are a number of things that can be done for the application process, starting with simple typo fixes in the documentation tree. Converting simple text documents to RST is a relatively straightforward task, but contacting the mentor first is recommended, since some parts of the documentation tree are more amenable to this work in the short term than others. We would also love to see fixes for the large number of warnings that are currently emitted as part of the build process.
