There are many ways for people to start out in Linux kernel development. One good place to start is the KernelJanitors project, where you can become familiar with the Linux kernel source tree and development style by making small cleanups and bug fixes all over the tree, together with the other kernel janitors.
For Kernel Hackers
Please add suitable projects here to help Computer Science students do something useful in the time they need to spend on projects anyway. Suitable projects:
- Are relatively self contained, so the code could be merged into the kernel after the student is done with the project.
- Have clearly defined functionality, so the student has goals and can determine whether (s)he achieved them.
- Can be of various sizes. Students need projects anywhere from 6 weeks part-time to 6 months full-time effort.
- If possible, are useful to the Linux kernel. Maybe something from your own TODO list that you did not get around to?
Small Linux features
A good next step is to implement small, relatively self contained, features that the Linux kernel needs but have not been implemented yet. When you "take" such a feature, please add your name in the "Developer" column and the date you decided to take the project in the "Date taken" column.

Project |
Summary |
Compressed Caching is a new level in the virtual memory hierarchy, where pages are stored in some compressed format, decreasing the number of page faults that are serviced by slow hard disks. |
|
The Linux1394 project has a seemingly ever-growing to-do list of bugs and other items, ranging from small cleanups to implementation of full drivers (e.g. IP over FireWire). If you have FireWire hardware, working on these drivers may be a good entry into kernel hacking because most FireWire specs are open, some even gratis. See the Wiki at linux1394.org for the to-do list and links to specifications. |
|
This project addresses some shortcomings (fairness, performance, privacy) of the TCP/IP Stack in mesh networks with a new layer3/4 protocol. Some things are running and need more testing. |
|
OpenSSI is a comprehensive clustering solution offering a full, highly available single-system image (SSI) environment for Linux. Development involves porting to newer kernels, regression testing, and fixing bugs in the clustering file system, process management, networking, IPC, shared memory, and init as well as userspace system utilities in a distributed computing environment. |
|
There are more than 1000 open bugreports in kernel bugzilla. The bugs to fix are of difficulty level 1-10 and there`s a lot to learn there, because nearly every part of the kernel gets touched. Please help identifying and fixing Linux kernel bugs. |
