We implement an open source conflict resolution framework that consists of a user-space C application that automatically resolves firewall rules anomalies, and b) a generic tree (called policy tree), implemented as a Linux kernel module which maintains the resolved firewall rules and enables the necessary hooks to netfilter for matching incoming (or outgoing) network packets. Tree-based data structures offer improved efficiency compared to traditional access control lists (e.g. iptables or nftable maps), especially for large systems with a huge number of rules. ...

This project contains the material discussed in my PhD dissertation, entitled "Hardware/Software Design of Dynamic Real-Time Schedulers for Embedded Multiprocessor Systems." The source code is available in the SVN repository: https://sourceforge.net/p/xrt/code/6/tree/trunk/ and consists in two folders: 1) /X-RT : A portable multiprocessor scheduling framework supporting scheduling periodic real-time tasks according to the G-EDF (Global Earliest Deadline First) scheduling platform. Current version supports major POSIX systems (Linux, QNX). 2) Hardware_GEDF_Scheduler: is a hardware implementation in VHDL (targeting FPGAs) of the G-EDF multiprocessor scheduling policy.
