Pre-RFC: BTF Relocations for Rust — Rust Internals

A series of discussions on the Rust Internals forum introduces a pre-RFC for BTF (BPF Type Format) relocations, proposing a new #[btf_preserve_access] attribute. This change aims to improve the compatibility of Rust with BPF (Berkeley Packet Filter) targets by preserving access to aggregate types during compilation. The proposal could significantly impact how Rust handles type layouts, especially in systems programming contexts where BPF is heavily utilized.

Improving Build Security in Rust — Rust Internals

The Rust community is actively discussing methods to enhance build security, focusing on sandboxing build scripts and proc-macros. Ideas include using Wasm for sandboxing and adding configuration options to standard libraries to prevent unsafe operations. These changes aim to protect Rust projects from potential vulnerabilities introduced during the build process, ensuring safer and more reliable software development.
