Ironclad - Networking developments

Real-time capable, UNIX-like operating system kernel in SPARK/ADA

Ironclad is a partially formally verified, hard real-time capable kernel for general-purpose and embedded uses, written in SPARK and Ada. It is comprised of 100% free software, free in the sense that it respects the user's freedom. By providing a UNIX-like interface which ensures an easy porting process from Linux and BSD distributions, Ironclad aims to be a solution for developers searching for a security-first, resilient platform with the smallest barrier to entry. This project will work on rewriting the networking subsystem from the ground up, adding a formally verified networking stack to Ironclad.
