• Rust in the Linux kernel just got a big boost from Google — The main goal of the push to bring Rust to Linux is to wipe out an entire class of memory-related security bugs in the kernel. This is important because, as Microsoft has recently highlighted, 70% of all bugs it fixes are memory-related. Historically, key Linux drivers that make up the kernel have been written in C, which is not memory-safe.
• Supporting Miguel Ojeda’s Work on Rust in the Linux Kernel — While this is the first memory safety effort we’ve announced under our new Prossimo project name, our memory safety work began in 2020. You can read about our efforts to bring memory safety to curl and the Apache HTTP server, and to add improvements to the Rustls TLS library.
