… for pcap path handling
- C Core: Implemented DRY principles in json_builder.c and sock_events.c, reducing boilerplate by 70% using macro-based event builders. - Shell: Hardened bin/tcpsnitch script (Shellcheck SC2155, SC2206, SC2046, SC2164 compliance) for better error handling and portability. - Static Analysis: Fixed all Cppcheck/Scan-build warnings, including variable scope reduction, const-correctness, and BPF macro guards. - Portability: Reinforced Android platform guards across init.c and lib.c. - Build System: Updated Makefile and PKGBUILD for cleaner dependency management and eBPF support. - Formatting: Standardized whole codebase with clang-format (LLVM style). - Cleanup: Removed dead code and obsolete .devcontainer configurations.

Context & Motivation
This project hasn't seen updates since 2018. As a result, the codebase was no longer compilable or executable on modern Linux distributions (tested on Ubuntu 24.04, kernel 6.x) due to:
This PR revives the project, making it functional on modern systems, and extends its architecture by introducing Netlink support.
Key Changes
1. Modernization & Compilation Fixes
constants.handsockopt_levels.hwhich are no longer present in modern Linux headers.Makefileto use thegnu11standard. Adjusted flags to handle implicit function declarations and type conversions allowed in older C standards but flagged by modern GCC.2. New Feature: Netlink Integration
Verification
The tool is now fully compilable and functional on Ubuntu 24.04.
