17k Lines of New Rust Kernel Code for Linux 7.4

Summary: Miguel Ojeda submitted his pull request for the new Rust kernel code slated for Linux 7.4. This update is substantial due to the inclusion of an updated Zerocopy vendored library and other Rust crates for the kernel.

Approximately 17,000 lines of new Rust code are being added to the Linux kernel 7.4. This indicates the continued adoption of the Rust language within the kernel development community. Rust is becoming increasingly popular for systems programming due to its memory safety and concurrency guarantees.

The added code includes an updated version of the Zerocopy library and other Rust crates for the kernel. Zerocopy is a technique aimed at improving I/O performance by reducing data copying overheads. Rust’s integration into the kernel allows for the development of safer and potentially more performant kernel modules.

For infrastructure and systems engineers, this creates an expectation of more stable and secure kernel modules in the future. Rust’s memory safety features can help reduce common kernel-level vulnerabilities (e.g., use-after-free, buffer overflow). This could lead to fewer unexpected crashes and higher uptime in production environments.

With the increasing prevalence of Rust-based kernel modules, new tools and competencies may be required for kernel development and debugging processes. It would be beneficial for engineers to gain familiarity with the Rust language to understand and manage these new developments.
