💻Linux Kernel Embraces Rust for New Work
Rust is coming to Linux, but not all at once
TL;DR
The Linux kernel is adopting Rust for new subsystems and drivers. Over 13 CVEs are reported daily, many due to C's inherent risks. Rust promises safer coding practices but won't rewrite the entire kernel immediately.
Linux is gradually integrating Rust into its development process, with a focus on new work in key subsystems like graphics drivers and IPC mechanisms such as Binder. This shift aims to reduce common vulnerabilities that stem from C's limitations. Over 13 CVEs are reported daily, many of which could be mitigated by Rust’s safety features. The transition is gradual, ensuring existing C code remains untouched while new projects embrace Rust for its robust security benefits.
Key Points
Over 13 CVEs reported daily to Linux kernel, many due to C's inherent risks
Rust adoption for new work in key subsystems such as graphics drivers and Binder
Binder now has parallel C and Rust implementations; C version will be phased out
Linux kernel leadership has officially endorsed Rust as a first-class language
150 core maintainers review the majority of Linux's 5,000+ developer contributions
Why It Matters
If you're working on new Linux subsystems or drivers, Rust adoption means safer coding practices and fewer vulnerabilities. For example, Binder's transition to Rust eliminates common C mistakes while maintaining backward compatibility. However, existing C code remains untouched, ensuring stability for legacy systems.
