| The application period for OPW Round 9 is September 12 to October 31. Most OPW organizations have an application deadline of October 22, however, the Linux kernel application period will be put on temporary hold from October 10 to October 20. Most kernel mentors will be attending conferences (LinuxCon Europe, Linux Plumbers Conf, and Embedded Linux Conference Europe) during that time. During the hold period, no new kernel application patches will be accepted or reviewed, and mentors may not be available on the IRC channel. Therefore, it is important to start sending patches early in the application period. We suggest that you tackle a medium-sized advanced project during that week, rather than preparing to send many small clean up patches after the hold period is finished. Please fill our your [https://live.gnome.org/OutreachProgramForWomen#Application_Process initial application] by October 22nd, and complete your initial kernel patch by October 31. Applicants that do not complete the first patch will not be considered for an internship. Please take a look at our [:OPWApply:application FAQ] for more info on how to fill our your initial application. Applicants will be notified on November 12 if they have been accepted. |
The application period for Outreachy Round 14 is February 16 to March 30. Please fill your [https://live.gnome.org/OutreachProgramForWomen#Application_Process application] by '''March 30''', and complete your kernel patch by '''March 30''' also (7pm UTC in both cases).

| ''Mentor'': Arnd Bergmann | After many years of relative neglect, we are working to improve the kernel's documentation; this includes [https://lwn.net/Articles/692704/ 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. |
| Line 64: | Line 71: |
| The concept of 'time' in Linux is encoded in many different ways, but the most common one is based on the 'time_t' type that counts the number of seconds that have passed since Jan 1, 1970. This type is currently defined as 'long', which on 32-bit systems is a signed 32-bit number that will overflow on Jan 19 2038 and likely cause existing systems to stop working, see [http://en.wikipedia.org/wiki/Year_2038_problem]. |
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. |
| Line 71: | Line 73: |
| On 64-bit systems, the problem is solved for the most part because 'long' is a 64-bit number that will not overflow for billions of years, but there are some important missing pieces such as file systems that store time in 32-bit quantities on disk as well support for 32-bit user space binaries running on 64-bit kernels. |

| Solving this problem in general is a huge effort involving lots of changes in the kernel as well as in user space. This project focuses on the kernel side, can be nicely split up into many small subtasks and is a prerequisite for doing the user space changes. There are currently 2117 instances of 'time_t', 'struct timespec' and 'struct timeval' in the kernel, and we are going to replace all of them with other types. Any isolated in-kernel uses of these types can be replaced with 'ktime_t' or 'struct timespec64'. For any interface to user space (typically an ioctl command or a system call) that passes a data structure based on these types, we have to keep the existing interface working and introduce an alternative interface that can be used by newly built user space programs. ["y2038"] has a deeper introduction to the topic and will be updated with more detailed subtasks over time. == IIO staging drivers cleanup == ''Mentors:'' [http://kernelnewbies.org/OctavianPurdila Octavian Purdila], [http://kernelnewbies.org/DanielBaluta Daniel Baluta] The [http://free-electrons.com/pub/conferences/2012/fosdem/iio-a-new-subsystem/iio-a-new-subsystem.pdf Industrial I/O subsystem] is intended to provide support for devices that in some sense are analog to digital or digital to analog converters. Some devices that fall in this category are: accelerometers, gyroscopes, light sensors, etc. This project will involve cleaning and moving IIO drivers out from staging. Most of the work will change drivers to use proper IIO ABI and adapt the code to follow the Linux Kernel coding style. We plan to start the with driver for Intersil ISL29018 digital ambient light and proximity sensor. Follow ["IIO cleanup"] page for small tasks and updates. |
