Writing Linux Kernel Modules in Safe Rust

Explore the potential of using Rust for Linux kernel development in this 48-minute conference talk by Geoffrey Thomas and Alex Gaynor. Delve into the challenges of creating binary-compatible kernel modules in Rust, techniques for interfacing with existing C code, and strategies for designing safe bindings over raw kernel APIs. Learn about the advantages and difficulties of integrating Rust into upstream kernel development, and discover possible future directions for the kernel community. Gain insights into memory safety issues in kernel vulnerabilities and understand how Rust's safety features can address these concerns. Examine topics such as uninitialized variables, structs, traits, generics, error handling, and concurrency in the context of kernel module development. Investigate the practical aspects of compiling, binding, and mapping kernel APIs to Safe Rust, as well as real-world applications for out-of-tree module usage and improved kbuild integration.
