Project mention: I want to learn about kernel development | reddit.com/r/developersIndia | 2022-11-28
Last but not the least, learning by doing is fun so you can check out - raspberry-pi-os (writing an os from scratch) - https://github.com/s-matyukevich/raspberry-pi-os

Ctrl-F "rust"
https://rust-for-linux.com/ links to LWN articles at https://lwn.net/Kernel/Index/#Development_tools-Rust that suggest that only basic modules are yet possible with the rust support in Linux kernels 6.2 and 6.3.
Rust-for-linux links to the Android binder module though:
> Android Binder Driver: This project is an effort to rewrite Android's Binder kernel driver in Rust.
> Motivation: Binder is one of the most security and performance critical components of Android. Android isolates apps from each other and the system by assigning each app a unique user ID (UID). This is called "application sandboxing", and is a fundamental tenet of the Android Platform Security Model.
> The majority of inter-process communication (IPC) on Android goes through Binder. Thus, memory unsafety vulnerabilities are especially critical when they happen in the Binder driver
... "Rust in the Linux kernel" (2021) https://security.googleblog.com/2021/04/rust-in-linux-kernel... :
> [...] We also need designs that allow code in the two languages to interact with each other: we're particularly interested in safe, zero-cost abstractions that allow Rust code to use kernel functionality written in C, and how to implement functionality in idiomatic Rust that can be called seamlessly from the C portions of the kernel.
> Since Rust is a new language for the kernel, we also have the opportunity to enforce best practices in terms of documentation and uniformity. For example, we have specific machine-checked requirements around the usage of unsafe code: for every unsafe function, the developer must document the requirements that need to be satisfied by callers to ensure that its usage is safe; additionally, for every call to unsafe functions (or usage of unsafe constructs like dereferencing a raw pointer), the developer must document the justification for why it is safe to do so.
> We'll now show how such a driver would be implemented in Rust, contrasting it with a C implementation. [...]
This guide with unsafe rust that calls into the C, and then with next gen much safer rust right next to it would be a helpful resource too.
What of the post-docker container support (with userspaces also written in go) should be cloned to rust first?

Project mention: Ask HN: Why the Linux Kernel doesn't have unit tests? | news.ycombinator.com | 2022-11-25
There are tests, they're just out of tree, focused on integration rather than unit, and very decentralized. You'll get nastygrams on lkml if you break them.
Here's one prominent example: https://github.com/linux-test-project/ltp

dattobd
kernel module for taking block-level snapshots and incremental backups of Linux block devices
https://github.com/datto/dattobd is still a thing, apparently. Needs its own kernel module, so have fun with that.

Project mention: Searchable Linux Syscall Table for x86 and x86_64 | news.ycombinator.com | 2023-04-14
This is an old resource, but one that helped me out a lot when writing a fault injection tool for Linux[1].

> Without being enabled by default, this project will go nowhere.
The maintainers of Linux distributions will enable it, if they see doesn't cause trouble with regular network traffic.
After all, there are instructions for the "old" implementation: <https://multipath-tcp.org/pmwiki.php/Users/ConfigureMPTCP>, <https://multipath-tcp.org/pmwiki.php/Users/ConfigureRouting> and the "new" implementation: <https://github.com/multipath-tcp/mptcp_net-next/wiki/#how-to...>.
