Rust for Linux Miguel Ojeda Wedson Almeida Filho Alex Gaynor Rust for Linux aims to add Rust support to the Linux kernel. We believe Rust offers key improvements over C in this domain. We hope improvement of Rust for everyone! Introduction Language Library Tooling Nightly features A general priority is to stabilize them (or to find alternatives): https://github.com/Rust-for-Linux/linux/issues/2 add w8, w10, w9 Language Memory model: future potential Unified/Compatible Linux kernel and Rust memory models: No need to use inline assembly to define a new memory model. Language-supported address

BENEFITS AND DRAWBACKS OF ADOPTING A SECURE PROGRAMMING LANGUAGE: RUST AS A CASE STUDY Kelsey Fulton, Anna Chan, Daniel Votipka, Michelle Mazurek, Michael Hicks 1 Memory safety vulnerabilities https://www.zdnet.com/article/chrome-70- of-all-security-bugs-are-memory-safety-issues/ Case Study: Rust ■ Attempt safety and performance (e.g., no GC) ■ Useful where C/C++ are hardest to replace ■ language? 3 Case Study: Rust ■ Semi-structured interview with senior developers (I = 16) ■ Survey with Rust community (S = 178) 4 Learning Rust ■ Rust is hard to learn. 5 Rust has “a near-vertical
