| == Coccinelle == ''Mentor:'': [:JuliaLawall:Julia Lawall] |
== Migrate NAND driver to new exec_op framework == |
| Line 35: | Line 34: |
| 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. | ''Mentor:'': [[ Eze Garcia|]] |
| 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.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. | === Major task === |

Its goal is to ease the support of complex NAND controllers, while also supporting legacy devices. In other words, it's meant to eventually replace ->cmd_ctrl(), ->cmdfunc() and ->read/write_byte/word/buf() hooks. Currently, a few drivers have been already converted, and others are in the process of being converted. However, many drivers will remain to be converted, some conversions being more complex than others. The goal of this project is to convert one or more NAND device drivers, removing the ->cmd_ctrl() uses and use ->exec_op() instead. |
| Line 44: | Line 44: |
| 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 selected intern will learn generic skills on Linux device drivers development. Also, they will learn specific skills about NAND technology, general MTD support in Linux and the new NAND framework. |
| Line 46: | Line 46: |
| 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. | === Small tasks === |
| Line 48: | Line 48: |
| We will provide you the hardware setup necessary to test the driver.

== radix tree __alloc_fd == ''Mentors:'': [:RikvanRiel:Rik van Riel] [: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 generic radix tree code, using a radix tree tag to keep track of where in the tree free file descriptor entries are. 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 * read how the radix tree code works * 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. == Project == ''Mentor:'': [:WikiName:Mentor names] Brief project description. |

Migrate NAND driver to new exec_op framework
Mentor:: Eze Garcia
Major task
Recently, a new NAND framework called "exec_op" was introduced, which sends specific NAND operations to a device, via a single ->exec_o() callback.
Its goal is to ease the support of complex NAND controllers, while also supporting legacy devices. In other words, it's meant to eventually replace ->cmd_ctrl(), ->cmdfunc() and ->read/write_byte/word/buf() hooks. Currently, a few drivers have been already converted, and others are in the process of being converted. However, many drivers will remain to be converted, some conversions being more complex than others. The goal of this project is to convert one or more NAND device drivers, removing the ->cmd_ctrl() uses and use ->exec_op() instead.
The selected intern will learn generic skills on Linux device drivers development. Also, they will learn specific skills about NAND technology, general MTD support in Linux and the new NAND framework.
Small tasks
Do not start on these tasks until after you complete the Linux kernel first patch tutorial (https://kernelnewbies.org/Outreachyfirstpatch) and Greg Kroah-Hartman has accepted at least ten of your cleanup patches and two of your patchsets.
The NAND subsystem does not seem to have many small tasks that applicants can engage. We propose to work generic cleanups (i.e. printk to pr_{} conversion), focused in the MTD and NAND subsystems.
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 then:
- Install a fresh Linux kernel, from git sources, and latest git snapshots for libmnl, libnftnl and nftables. You can find more information on how to set up your enviroment at wiki.nftables.org.
- Make sure you understand basic operational of nftables, read existing documentation.
- Once you're fully set up, you got basic understanding of the tooling and everything is working on your side, then contact the mentor to request for an initial task.
For more information on nftables, please check: http://wiki.nftables.org
Yeah, that sounds cool!
