Adds BootMediaManager for USB Mass Storage LUN image management: Core Features: - Thread-safe with RLock for reentrant operations - 4R double-buffer pattern (active/shadow slots) - Image validation (FAT32/ext magic, size constraints 16MiB-4GiB) - SHA256 integrity verification - Atomic symlink swaps for zero-downtime updates - TFTP boot file extraction (optional, disabled in test mode) Functions Implemented: - validate_image(): Check FAT32/ext magic and size limits - upload_to_shadow(): Stream upload with hash computation - swap(): Atomic active↔shadow exchange with LUN detach/reattach - rollback(): Convenience wrapper for swap operation - get_state(): Read current state from symlinks and state.json Technical Details: - Uses RLock instead of Lock to prevent deadlock (get_state called from swap) - Subprocess calls for gadget-setup.sh LUN management - Test mode flag (SECUBOX_TEST_MODE) to skip TFTP extraction - State persistence in /var/lib/secubox/eye-remote/boot-media/state.json Tests: - 18 integration tests covering all operations - Mock subprocess.run for gadget script calls - Validates atomic operations and state persistence Next: Task 5 - FastAPI router endpoints Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
