itlwm is a macOS network driver and kernel extension that enables Intel wireless network adapters to function on macOS systems. It serves as a hardware-specific driver providing connectivity and stability for Intel Wi-Fi chips on non-native platforms. The project acts as a bridge between Intel hardware and native macOS wireless frameworks, allowing the system to recognize the adapter as a native device and utilize Apple Airport features and system settings. The driver manages hardware integration and network connectivity by interfacing with the operating system to support macOS hardware comp

This is a structured reference that maps Linux kernel network sysctl parameters to their specific roles in the packet processing pipeline, from the network interface card through to the application layer. It covers the full path of packet traversal, including interrupt mitigation, buffer management, queuing disciplines, and TCP auto-tuning mechanisms. The reference details how to configure kernel parameters for connection handling, including TCP listen backlog, SYN queue management, FIN timeout, and syncookies. It also addresses queue management and bufferbloat control through egress queuing

Katran este un load balancer de Layer 4 bazat pe eBPF, conceput pentru redirecționarea pachetelor de rețea de înaltă performanță direct în kernel-ul Linux. Utilizează un procesor de pachete de rețea XDP pentru a ocoli stiva standard de rețea a kernel-ului, minimizând latența și maximizând throughput-ul pentru traficul de intrare. Sistemul implementează hashing consistent ponderat pentru a distribui sarcinile de rețea și a menține persistența sesiunii pe serverele backend. Optimizează în continuare calea de retur printr-un gateway de tip direct server return, care permite backend-urilor să răspundă direct clienților și elimină load balancer-ul din fluxul de trafic de ieșire. Capabilitățile sale includ urmărirea conexiunilor fără blocaje (lockless) pentru stabilitatea sesiunii și binding-ul nucleelor conștient de NUMA pentru a elimina latența între noduri. Proiectul suportă, de asemenea, ponderarea traficului către backend, drenarea serverelor și înlănțuirea programelor XDP pentru executarea logicii de firewall înainte de load balancing. Implementarea oferă instrumente de observabilitate pentru capturarea traficului de rețea, rutarea sondelor de healthcheck și filtrarea traficului încapsulat.

This project provides an open-source VPN client that creates an unrestricted tunnel to bypass internet censorship without fees, registration, speed caps, or data limits. It offers free, unlimited VPN tunneling with no sign‑up required, enabling access to blocked websites and unrestricted browsing. The application uses the WireGuard protocol for encrypted traffic routing, backed by kernel‑level packet forwarding to minimize overhead. It includes automatic server discovery that selects the most responsive server based on real‑time latency, a connection keepalive mechanism to detect and restore

Aya is a Rust-native framework for writing, compiling, and loading eBPF programs into the Linux kernel. It provides a complete development environment that eliminates the need for a C toolchain or libbpf, allowing developers to work entirely within the Rust ecosystem. The framework manages the full lifecycle of eBPF programs, including async runtime integration, CO-RE BTF resolution for kernel version portability, ELF-based program loading, and safe kernel memory access. The framework distinguishes itself through its pure Rust compilation pipeline, which compiles Rust source code directly int
