v0.3.0 — Event-Driven API

v0.3.0 - 2026-06-24

Added

• pkg/results: \HostResult\ — canonical host result type with \Alive/\OpenPorts\ and JSON tags \�live/\open_ports. Replaces \DeviceInfo\ as interchange format for the event-driven API.
• pkg/results: \HostResult.ToDeviceInfo()\ — conversion for compatibility with \DeviceInfo.
• pkg/profile: \ScanProfile, \DefaultProfile, \Sanitize\ — scan configuration with \DefaultPorts, \Concurrency, \TimeoutMs\ and JSON tags.
• pkg/events: \Event, \EventType\ (string-based), \HostDiscoveredData, \ProgressData\ — async event system via channel.
• pkg/export: \ExportJSON, \ExportCSV\ for []results.HostResult\ with CSV sanitization.
• pkg/scan: \Engine, \NewEngine, \ScanStream, \Stop\ — event-driven orchestrator delegating scan logic to \pkg/engine.
• pkg/scan: \Ping, \ReverseDNS, \GetMAC, \ScanPorts\ — delegation wrappers for \pkg/discovery\ and \pkg/ports.
• Tests: Tests for all new packages (\pkg/results, \pkg/events, \pkg/profile, \pkg/export, \pkg/scan).

Changed

• pkg/results/HostResult: Changed from type alias to \DeviceInfo\ to independent struct with \Alive/\OpenPorts\ fields and JSON tags (\�live/\open_ports). Existing code using \DeviceInfo\ is unaffected.
• pkg/events/EventType: Changed from \int\ (iota) to \string\ for easier serialization in Wails and TUI frontends.

Notes

• \pkg/engine, \pkg/discovery, \pkg/ports, \pkg/exporter, \pkg/fingerprint, \pkg/topology, \pkg/coreerr\ preserved unchanged.
• No external dependencies added — stdlib Go only.

v0.2.0

Changelog

0.2.0 - 2026-06-21

Added

• Topology Graph Support (pkg/topology/): Complete network topology graph builder with gateway identification, device clustering by subnet, and graph export capabilities.
• OS/Device Fingerprinting Enhancements:
  • OUI (Organizationally Unique Identifier) module with zero-allocation lookup for MAC vendor identification.
  • TTL (Time To Live) fingerprinting module for OS detection.
  • Banner fingerprinting support for service identification.
  • Comprehensive test suites and benchmarks for all fingerprinting modules.
• DevSecOps Documentation: Added docs/devsecops.md with security practices, vulnerability scanning procedures, and fuzzing guidelines.
• Enhanced CI/CD Infrastructure:
  • Golangci-lint configuration (.golangci.yml) with strict linting rules.
  • Dependabot automation for dependency updates (dependabot.yml).
  • Fuzz testing CI workflow for automatic fuzzing on pull requests.
  • Govulncheck PR workflow for automated vulnerability scanning.
  • GPG-signed commit workflow for supply chain security.
  • Automated develop→main merge workflow with GPG signing.

Changed

• Performance Optimizations (Zero-Allocation Patterns):
  • ⚡ ARP table parsing in MAC discovery now uses zero-allocation parsing.
  • ⚡ VendorFromMAC lookup optimized for minimal memory allocations with dedicated benchmarks.
  • ⚡ Subnet extraction (/24) in topology builder uses zero-allocation string slicing.
  • ⚡ Topology graph edge keys replaced with zero-allocation struct keys, eliminating string concatenation overhead.
• Port Scanner Improvements: Enhanced port scanning logic with better concurrency handling and timeout calculations.
• CI Workflow Updates: Refactored CI workflows for better separation of concerns and improved maintainability.
• Dependency Updates:
  • actions/checkout: Bumped from v4 to v7 for enhanced features and security fixes.
  • actions/setup-go: Bumped from v5 to v6 for improved Go version handling.

Fixed

• POSIX osPing Enhancement: Improved timeout parameter handling to properly convert milliseconds to whole seconds for Linux (-W flag) and milliseconds for macOS.
• Golangci-lint Version Mismatch: Fixed CI compilation issue by compiling golangci-lint from source when necessary.

Security

• All commits are now GPG-signed via automated workflow for supply chain integrity.
• Added regular vulnerability scanning with govulncheck.
• Enhanced CI linting with golangci-lint and security-focused configuration.
