If you are interested in following this effort, please join us in the mailing list at: rust-for-linux@vger.kernel.org and take a look at the project itself at: https://github.com/Rust-for-Linux As usual, special thanks go to ISRG (Internet Security Research Group) and Google for their financial support on this endeavor. Cheers, Miguel --- # Rust support This cover letter explains the major changes and updates done since the previous ones. For those, please see: RFC: https://lore.kernel.org/lkml/20210414184604.23473-1-ojeda@kernel.org/ v1: https://lore.kernel.org/lkml/20210704202756.29107-1-ojeda@kernel.org/ v2: https://lore.kernel.org/lkml/20211206140313.5653-1-ojeda@kernel.org/ v3: https://lore.kernel.org/lkml/20220117053349.6804-1-ojeda@kernel.org/ ## Infrastructure updates There have been several improvements to the overall Rust support: - The Intel 0DAY/LKP kernel test robot is setting up Rust in their CI -- we already got the first reports from the bot which we could act upon, very useful! - KernelCI is also looking forward to enabling Rust in their runs. - The GitHub CI we use for quick pre-merge testing has been moved to use containers. - Kernel modules do not need to write the crate attributes `#![no_std]` and `#![feature(...)]` anymore, removing boilerplate. - Added single target support, including `.o`, `.s`, `.ll` and `.i` (i.e. macro expanded, similar to C preprocessed sources). - Explanation of the `helpers.c` file and licensing for helpers and exports. - The documentation logo is now vector based (SVG). In addition, a vector version of Tux has been proposed for upstream, and an RFC for improved custom logo support has been submitted to upstream Rust. - Added coding guidelines on comments (`//`) and code documentation (`///`). - `is_rust_module.sh` rework. - Generation of `.rmeta` for leaf modules is skipped now. - Other cleanups, fixes and improvements. ## Abstractions and driver updates Some of the improvements to the abstractions and example drivers are: - Added support for static (global shared variables) synchronization primitives. `CONFIG_CONSTRUCTORS` are used for the implementation. - Simplification of the lock guards by using marker types, i.e. `Guard` and `GuardMut` are unified into a single parametrized type. If the marker is `WriteLock`, then `Guard` implements `DerefMut` (only implemented by `GuardMut` previously). - Optional parameters added to the registration of misc devices, following the builder pattern., e.g. miscdev::Options::new() .mode(0o600) .minor(10) .parent(parent) .register(reg, c_str!("sample"), ()) - Added `RwSemaphore` abstraction that wraps the C side `struct rw_semaphore`. - New `mm` module and VMA abstraction (wrapping the C side `struct vm_area_struct`) for use with `mmap`. - GPIO PL061 now uses the recently added `dev_*!` Rust macros. - Support the `!CONFIG_PRINTK` case. - Other cleanups, fixes and improvements. ## Patch series status The Rust support is still to be considered experimental. However, support is good enough that kernel developers can start working on the Rust abstractions for subsystems and write drivers and other modules. The current series has just arrived in `linux-next`, as usual. Similarly, the preview docs for this series can be seen at: https://rust-for-linux.github.io/docs/kernel/ As usual, please see the following link for the live list of unstable Rust features we are using: https://github.com/Rust-for-Linux/linux/issues/2 ## Acknowledgements The signatures in the main commits correspond to the people that wrote code that has ended up in them at the present time. For details on contributions to code and discussions, please see our repository: https://github.com/Rust-for-Linux/linux However, we would like to give credit to everyone that has contributed in one way or another to the Rust for Linux project. Since the previous cover letter: - Philip Li, Yujie Liu et. al. for setting the Intel 0DAY/LKP kernel test robot with Rust support. - Maciej Falkowski for continuing his work on the Hardware Random Number Generator subsystem, Samsung Exynos true random number generator, clock subsystem, etc. - bjorn3 for an extensive re-review of the previous round. - Jonathan Corbet for his feedback on the previous round. - Garrett LeSage and IFo Hancroft for agreeing to the usage of their vector version of Tux within the kernel tree with the same license as the existing one from Larry Ewing. - Nathan Chancellor for noticing a case where a C module was being identified as a Rust one for purposes of skipping BTF generation and suggesting a few improvements around `is_rust_module.sh`. - Wei Liu for exporting the remaining helpers and triggering a useful discussion around it. - Miguel Cano for fixing an issue with compilers containing a full, 3-part version in the suffix part (e.g. Ubuntu Clang). - Abhik Jain for working on adding missing `// SAFETY` comments and `# Safety` sections to the code generated by the `module!` macro. - Jiapeng Chong and the Abaci Robot for reporting and fixing an unneeded header `#include`. - Finn Behrens for resuming his work on building Rust for Linux on Nix and spotting and fixing usability issues. - As usual, Gary Guo and bjorn3 for all the input on Rust compiler details and all the reviews and suggestions. - John Ericson, TennyZhuang and Xuanwo for their ongoing work on adding more fallible allocation methods (`try_*`) to the Rust standard library. - Stephan Sokolow and Mark Rousskov for their feedback on the custom documentation logo RFC. - Philip Herrons (and his supporters Open Source Security and Embecosm) et. al. for their ongoing work on GCC Rust. - Antoni Boucher (and his supporters) et. al. for their ongoing work on `rustc_codegen_gcc`. - Mats Larsen, Marc Poulhiès et. al. for their ongoing work on improving Rust support in Compiler Explorer. - Many folks that have reported issues, tested the project, helped spread the word, joined discussions and contributed in other ways!
