OutreachyIntro

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 13 will start on September 12, 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 13 funding sponsors and Linux kernel mentors. Please see the linked FAQ pages if you want to help out.

Welcome Outreachy applicants! Our round 13 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.

How to apply

The application period for Outreachy Round 13 is September 12 to October 17. Please fill your application by October 17, and complete your kernel patch by October 17 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.

If you are interested in being a Linux kernel intern, please:

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 13 projects

Previous projects, from round 12 projects are available here. For each project, if you click on the proposer's name, you may find more information.

Coccinelle

Mentor:: Julia Lawall

Coccinelle is a program matching and transformation tool that has been extensively used for improving Linux kernel code. This project will involve using Coccinelle to address a security issue in the Linux kernel.

The Linux kernel contains many data structures whose contents never change once they are initialized, many of which contain function pointers. Such structures that are modifiable at run time constitute a security risk, because an attacker may be able to overwrite the field value with a pointer to malicious code, that will then be executed with full kernel privileges. The first goal of this project is to use Coccinelle to insert const annotations on such structures to prevent runtime modfications. Some structures, however, cannot be made const, because they are initialized in several steps. In these cases, it may be possible to annotate the structure as __ro_after_init, if all of the initializations can take place during the init phase. The second goal is to add __ro_after_init where they are needed. This may requiring adding __init annotations on some code that is actually only needed during the init phase.line bash script. Please indicate in your application whether you are interested in this part of the project, however, interest in this part of the project is not a prerequisite for being selected as an intern.

More information about Coccinelle is available here, including a tutorial. For some Coccinelle small tasks, click on the mentor name.

IIO driver

Mentor:: Alison Schofield and Daniel Baluta

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 consider solving the IIO tasks.

nftables

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 wiki.nftables.org 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 bugzilla.netfilter.org.

For more information on nftables, please check: http://wiki.nftables.org
