* feat: add reverse DNS resolution for IP addresses
- Add --resolve-dns flag to enable background DNS resolution
- Add --show-ptr-lookups flag to show/hide PTR lookup connections
- Create dns.rs module with async resolver and LRU cache
- Display hostnames in UI with 'd' key toggle
- Include hostname fields in JSON log output when resolved
Closes#97
Changed bandwidth sorting to use the sum of upload and download speeds
instead of separate sorting for each direction. This provides a simpler
way to identify connections with the highest total bandwidth usage.
- Replace BandwidthDown/BandwidthUp with single BandwidthTotal enum
- Update sort logic to calculate combined rates
- Simplify UI to show "Down/Up ↓/↑" indicator
- Update documentation and tests
- Add Windows process lookup using GetExtendedTcpTable/GetExtendedUdpTable
- Resolve process names via OpenProcess and QueryFullProcessImageNameW
- Support TCP/UDP IPv4 and IPv6 connections
- Implement time-based caching with 2-second TTL
- Fix port byte order conversion from network to host order
- Migrate from winapi to windows crate (v0.59)
- Add debug logging for process lookup operations
- Update documentation in ROADMAP.md and README.md
Closes#36
* feat: Add experimental eBPF support for enhanced socket tracking
- Implement eBPF-based socket tracker for Linux with CO-RE support
- Add minimal vmlinux header (5.5KB) instead of full 3.4MB file
- Create graceful fallback mechanism to procfs when eBPF unavailable
- Add comprehensive eBPF build documentation
- Integrate libbpf-rs for eBPF program loading and management
- Support both IPv4 and IPv6 socket tracking
- Add capability checking for required permissions
The eBPF feature is optional and disabled by default. When enabled,
it provides faster and more accurate process-to-socket mapping on
Linux systems with appropriate permissions.
