Linux_Patch_API - Development Roadmap

Project Timeline Overview

Start Date: 2026-04-09
Target Production: 2026-07-17
Total Duration: 14 weeks (Aggressive timeline)
Phase Strategy: Sequential (no overlap)

Project Phases

Phase 0: Rust Project Scaffolding

Duration: 3 days
Target Date: 2026-04-09 to 2026-04-12
Status: Ready to Start

  • Initialize Rust project with Cargo
  • Set up project structure (src/, tests/, configs/)
  • Configure Cargo.toml with dependencies (actix-web, tokio, openssl, serde, etc.)
  • Set up Clippy and rustfmt for code quality
  • Create initial module structure (api, auth, jobs, packages, config, logging)
  • Configure .gitignore for Rust projects
  • Set up initial logging framework

Phase 1: Foundation

Duration: 2 weeks
Target Date: 2026-04-12 to 2026-04-26
Status: Not Started

  • Complete all specification documents ✅ (in progress)
  • Set up development environment (Rust toolchain, IDE config)
  • Initialize git repository ✅ (complete)
  • Configure CI/CD pipeline (GitHub Actions or GitLab CI)
  • Establish security baseline (dependency scanning, cargo-audit)
  • Set up test framework (cargo test, integration test structure)
  • Create systemd service file template
  • Set up internal CA infrastructure for mTLS certs

Phase 2: Core API Development

Duration: 6 weeks
Target Date: 2026-04-26 to 2026-06-07
Status: Not Started

  • Implement mTLS authentication layer
  • Implement IP whitelist enforcement
  • Build configuration management (YAML loading, validation, auto-reload)
  • Build job manager (queue, status tracking, WebSocket broadcast)
  • Implement Package Management endpoints:
    • GET /api/v1/packages (list/filter/sort)
    • GET /api/v1/packages/{name} (details)
    • POST /api/v1/packages (install)
    • PUT /api/v1/packages/{name} (update)
    • DELETE /api/v1/packages/{name} (remove)
  • Implement Patch Management endpoints:
    • GET /api/v1/patches (list available)
    • POST /api/v1/patches/apply (apply patches)
  • Implement System endpoints:
    • GET /api/v1/system/info
    • GET /api/v1/health
    • POST /api/v1/system/reboot
  • Implement Job Management endpoints:
    • GET /api/v1/jobs (list)
    • GET /api/v1/jobs/{id} (status)
    • POST /api/v1/jobs/{id}/rollback
  • Implement WebSocket streaming (/api/v1/ws/jobs)
  • Implement audit logging (systemd journal + file fallback)
  • Unit test coverage >95%
  • Integration tests for all endpoints

Phase 3: Security Hardening

Duration: 3 weeks
Target Date: 2026-06-07 to 2026-06-28
Status: Not Started

  • Penetration testing (internal/external)
  • Threat model validation (verify all STRIDE mitigations)
  • Security control implementation review
  • Fuzz testing on API endpoints
  • Certificate validation testing
  • Config file tampering resistance testing
  • Privilege escalation testing
  • Fix all security findings
  • Security documentation completion

Phase 4: Production Readiness

Duration: 3 weeks
Target Date: 2026-06-28 to 2026-07-17
Status: Not Started

  • Performance optimization (benchmarking, profiling)
  • Documentation completion (README, deployment guide, API docs)
  • Deployment automation (package creation: .deb, .rpm)
  • Installation script development
  • User acceptance testing
  • Final security review
  • Production deployment checklist
  • Release v1.0.0
