| The Linux kernel ethernet drivers communicate with network hardware, to give you access to the Internet. Ethernet devices can be as simple as the 1 gigabit ethernet controllers in your laptop, to much faster ethernet controllers in servers. | 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.

This includes early boot code, etc. This part of the kernel is usually considered one of the more complex areas of the operating system. However, with a bit of guidance, it's really fascinating to see how a computer begins the journey from powered off to a blinking cursor at your login prompt. Interns would work alongside PJ on central boot code in the Linux kernel. Today, the kernel brings CPU's online one by one in a serial fashion. We can do better. Several stages of changes are planned to go from a completely serial approach to a fully parallel approach to bringing CPU's up. Interns would work on some of these planned changes. ''Required skills:'' Knowledge of how to use and manipulate pointers and function pointers in C is a must. ''Optional but learnable skills:'' Knowledge of computer architecture, x86 assembly ''Mentors:'' Peter Waskiewicz Jr (PJ) [:PeterWaskiewicz:(contact info)] == Driver cleanups == Not all Linux kernel drivers are immaculate, pristine, and perfect pieces of code. Specifically, the code that lives in the drivers/staging/ area of the Linux kernel source tree need lots of help and cleanups in order to get them up to the expected level of rosbustness and readability that the rest of the Linux kernel is known for. These drivers live all come with a TODO file that lists what needs to be done to them in order to get them cleaned up. These tasks range from the simple "fix coding style issues" and "remove unused code", to the more complex "port the driver to the proper wireless stack", so a wide range of skills can be learned if desired. Interns would pick one of these drivers to clean up, submitting patches that address the TODO items, and eventually, help move it out of the staging area of the kernel, to the "proper" location. Having the hardware that is being controlled by these drivers is not necessary, but if desired, it can be found and shipped to the Intern doing the work. ''Required skills:'' Basic knowledge of the C language is needed, and the ability to build and boot a custom-built Linux kernel is desired. ''Mentors:'' Greg Kroah-Hartman [:GregKH:(contact info)] |
