Main Program (main.rs):
- Command-line interface using clap with comprehensive options
- eBPF program lifecycle management (load, configure, attach)
- Integration with structured logging system
- Graceful shutdown handling with log flushing
Command-Line Options:
- Interface selection for XDP attachment
- Configuration file path for CIDR ranges
- Packet action control (log-only vs drop)
- Logging format selection (console/json/csv/jsonl)
- Output file specification and buffer size tuning
- Verbose logging for debugging
eBPF Integration:
- Automatic eBPF program loading and BTF initialization
- CIDR range configuration via eBPF maps
- Real-time event processing from ring buffers
- XDP attachment with fallback to SKB mode
Enhanced Features:
- Structured event logging with flow correlation
- Real-time statistics and periodic summaries
- Signal handling for clean shutdown
- Error handling with context preservation
