| 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. | In laptops, tablets, phones and lots of other places GPU/display uses more silicon die space than everything else combined (humans are mostly visual people after all), dri-devel (and the wider set of projects under the X.org Foundation's umbrella) is the community that makes this all work and shine. |
| Line 37: | Line 36: |
| 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. | We have a bunch of janitorial-type projects collected in [[https://dri.freedesktop.org/docs/drm/gpu/todo.html]], varying from fairly mechanical to really challenging. We're also taking the usual array of checkpatch and coccinelle driven cleanup patches (they're great newbie starter patches). For an internship this means there's a lot of "build your own internship program", and we're definitely open to other projects. Just chat with mentors to start scoping a good project and what might be interesting for you. |

It would benefit from someone sorting through it, looking for missing coverage (maybe use gcov), and adding tests to exercise the missing functionality. This project involves working primarily in user-space as the kernel code is pulled into userspace and compiled there. We could also use performance tests (Konstantin Khlebnikov recently posted patches that adds one performance test) The radix tree test suite was adapted from outside the kernel tree recently, and does not yet share much of the common test infrastructure, eg tools/include/ == radix tree __alloc_fd == ''Mentors:'': [:RikvanRiel:Rik van Riel] and [:MatthewWilcox:Matthew Wilcox] Currently sys_open() uses a linear search through a bitmap to find the first free file descriptor. This custom code could be replaced with the IDR interface. This replaces some custom code in the kernel with generic code (hopefully shrinking the size of the kernel), could result in some memory savings for processes with relatively few open files, and hopefully improve performance of workloads with very large numbers of open files. If you think you may be interested in this project, here are some small tasks to start with: * read how sys_open() currently finds the first open file descriptor, and allocates/resizes the file descriptor table * understand the IDR API * email Matthew and Rik a description of your findings, and a proposed project time line If you have any questions, please email Matthew and Rik. == radix tree PID allocation == ''Mentors:'': [:RikvanRiel:Rik van Riel] and [:MatthewWilcox:Matthew Wilcox] The PID allocator is a good match for the IDR API, but it currently uses its own custom allocator. Similar to the {{{__alloc_fd}}} project above, after understanding the IDR API, read how alloc_pid() works (paying particular attention to PID namespaces!) and come up with a project plan. |

How to apply
The application period for Outreachy Round 15 is September 7 to October 23. Please fill your application by October 23, and complete your kernel patch by October 23 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.

Use our tutorial to send in your first kernel patch by October 23.
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.

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 linux-iio@vger.kernel.org
