HevSocks5Tunnel is a lightweight, high-performance tun2socks proxy written in C. It creates a virtual TUN interface and forwards all TCP/UDP traffic through a SOCKS5 proxy, supporting IPv4/IPv6 dual-stack, UDP-in-UDP and UDP-in-TCP relay modes, optional local ICMP echo replies, and a mapped DNS feature for transparent DNS resolution. The architecture is monolithic but modular: a YAML-based configuration parser, platform-specific tunnel backends (Linux, FreeBSD, macOS, NetBSD, Windows via Wintun), and a session management layer built on top of lwIP and the hev-task-system cooperative multitasking library. It can be used as a standalone CLI tool, a static/shared library, or embedded via JNI on Android. The codebase demonstrates strong C craftsmanship with clean abstractions, efficient I/O patterns (ring buffer with iovec, scatter/gather), and careful platform abstraction.
This is an Android application that serves as a GUI client for XTLS/Xray-core, a proxy/VPN tool. The app provides a comprehensive interface for managing proxy profiles, subscription links, and VPN configurations. It supports both standard VPN mode (using tun2socks) and transparent proxy mode (requiring root). The architecture follows MVVM with Room database for persistence, coroutines for async operations, and a native Go library (XrayCore) for core proxy functionality. The codebase is well-structured, using modern Android development practices (Kotlin, Jetpack libraries, Material Design 3). It includes features like QR code scanning, clipboard import, link management with auto-refresh, per-app routing, and a quick settings tile. The app is actively maintained with frequent updates and a CI/CD pipeline for release builds.
