Fix 4 critical bugs in GuruRMM agent update system
...
Resolves issues that could cause agent failure, stuck updates, and
silent errors during the update process.
Critical Fixes:
1. Binary Replacement Race Condition (Unix)
- PROBLEM: Window between rename and copy where no binary exists
- FIX: Use atomic rename pattern - copy to temp in same directory,
then single atomic rename operation
- IMPACT: Eliminates complete agent failure on crash during update
2. Update Failure Without Rollback
- PROBLEM: If restart fails after update, no rollback triggered
- FIX: Added rollback_binary() method, explicitly rolls back on
restart failure before returning error
- IMPACT: Agent no longer stuck in broken state
3. Windows Scheduled Task Timing Bug
- PROBLEM: Scheduled time could be in past, schtasks would fail
- FIX: Add 60-second buffer, return date+time tuple with /SD param
- IMPACT: Rollback watchdog now reliably schedules on Windows
4. Windows Binary Replacement Error Handling
- PROBLEM: All errors silently ignored with .ok()
- FIX: Proper error propagation with .context() on all operations
- IMPACT: Update failures now visible with actionable error messages
Code Review: APPROVED
- All fixes correctly address root causes
- Atomic operations eliminate race conditions
- Comprehensive error handling throughout
- Platform-specific code properly isolated
Testing: Syntax verified (cross-compilation toolchain not available)
Additional Issues Identified (for follow-up):
- HIGH: Unix watchdog doesn't survive reboots (systemd timer needed)
- MEDIUM: No concurrent update protection (lock file recommended)
- LOW: chmod failure should be fatal

Implement GuruRMM Phase 1: Real-time tunnel infrastructure
...
Complete bidirectional tunnel communication between server and agents,
enabling persistent secure channels for future command execution and
file operations. Agents transition from heartbeat mode to tunnel mode
on-demand while maintaining WebSocket connection.
Server Implementation:
- Database layer (db/tunnel.rs): Session CRUD, ownership validation,
cleanup on disconnect (prevents orphaned sessions)
- API endpoints (api/tunnel.rs): POST /open, POST /close, GET /status
with JWT auth, UUID validation, proper HTTP status codes
- Protocol extension (ws/mod.rs): TunnelOpen/Close/Data messages,
agent response handlers (TunnelReady/Data/Error)
- Migration (006_tunnel_sessions.sql): tech_sessions table with
partial unique constraint, foreign keys with CASCADE, audit table
Agent Implementation:
- State machine (tunnel/mod.rs): AgentMode (Heartbeat ↔ Tunnel),
channel multiplexing, concurrent session prevention
- WebSocket handlers (transport/websocket.rs): Open/close tunnel,
mode switching without dropping connection, cleanup on disconnect
- Protocol extension (transport/mod.rs): TunnelReady/Data/Error
messages matching server definitions
- Unit tests: Lifecycle and channel management coverage
Key Features:
- Security: JWT auth, session ownership verification, SQL injection
prevention, constraint-based duplicate session blocking
- Cleanup: Automatic session closure on agent disconnect (both sides),
channel cleanup, graceful state transitions
- Error handling: Proper HTTP status codes (400/403/404/409/500),
comprehensive Result types, detailed logging
- Extensibility: Channel types ready (Terminal/File/Registry/Service),
TunnelDataPayload enum for Phase 2+ expansion
Phase 1 Scope (Implemented):
- Tunnel session lifecycle management
- Mode switching (heartbeat ↔ tunnel)
- Protocol message routing
- Database session tracking
Phase 2 Next Steps:
- Terminal command execution (tokio::process::Command)
- Client WebSocket connections for output streaming
- Command audit logging
- File transfer operations
Verification:
- Server compiles successfully (0 errors)
- Agent unit tests pass (tunnel lifecycle, channel management)
- Code review approved (protocol alignment verified)
- Database constraints enforce referential integrity
- Cleanup tested (session closure on disconnect)

...
Created comprehensive VPN setup tooling for Peaceful Spirit L2TP/IPsec connection
and enhanced agent documentation framework.
VPN Configuration (PST-NW-VPN):
- Setup-PST-L2TP-VPN.ps1: Automated L2TP/IPsec setup with split-tunnel and DNS
- Connect-PST-VPN.ps1: Connection helper with PPP adapter detection, DNS (192.168.0.2), and route config (192.168.0.0/24)
- Connect-PST-VPN-Standalone.ps1: Self-contained connection script for remote deployment
- Fix-PST-VPN-Auth.ps1: Authentication troubleshooting for CHAP/MSChapv2
- Diagnose-VPN-Interface.ps1: Comprehensive VPN interface and routing diagnostic

- Add-PST-VPN-Route-Manual.ps1: Manual route configuration helper
- vpn-connect.bat, vpn-disconnect.bat: Simple batch file shortcuts
- OpenVPN config files (Windows-compatible, abandoned for L2TP)
Key VPN Implementation Details:
- L2TP creates PPP adapter with connection name as interface description
- UniFi auto-configures DNS (192.168.0.2) but requires manual route to 192.168.0.0/24
- Split-tunnel enabled (only remote traffic through VPN)
- All-user connection for pre-login auto-connect via scheduled task
- Authentication: CHAP + MSChapv2 for UniFi compatibility

- documentation-squire.md: Documentation and task management specialist agent
- Updated all agent markdown files with standardized formatting
Project Organization:

- Cleaned up old session JSONL files from projects/msp-tools/
- Added guru-connect infrastructure (agent, dashboard, proto, scripts, .gitea workflows)
- Added guru-rmm server components and deployment configs
Technical Notes:
- VPN IP pool: 192.168.4.x (client gets 192.168.4.6)
- Remote network: 192.168.0.0/24 (router at 192.168.0.10)
- PSK: rrClvnmUeXEFo90Ol+z7tfsAZHeSK6w7
