Concurrency in Rust Alex Crichton ## What's Rust? Rust is a systems programming language that runs blazingly fast, prevents segfaults, and guarantees thread safety. ## Concurrency? Rust? Libraries • Deadlocks • Use after free Exploitable! • Double free Concurrency? Rust? Libraries Futures ## What's Rust? Rust is a systems programming language that runs blazingly fast, prevents segfaults auto& elem = vector[0]; vector.push_back(some_string); cout << elem; } ## Rust's Solution Ownership/Borrowing ![Image](/uploads/documents/2/5/1/a/251a4de80215d513d0e0eec7b2453b6c/p11_1

## Rust for Linux Miguel Ojeda Wedson Almeida Filho Alex Gaynor ## I ntroduction Rust for Linux aims to add Rust support to the Linux kernel. We believe Rust offers key improvements over C in this domain in the improvement of Rust for everyone! 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 } } ## 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 # Memory safety vulnerabilities remain 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 What language? ## Case Study: Rust ■ Semi-structured interview with senior developers (I = 16) ☑ Survey with Rust community (S = 178) ## Learning Rust ☑ Rust is hard to learn. ### Rust has “a near-vertical learning
