DaLaw2 48effea826 fix: address PR #19 review feedback across 22 issues
Correctness:
- ml/config_loader: gate output_names check on adapter kind so
  Binary/Multiclass/Autoencoder manifests load cleanly
- ml/model_watcher: try_send in notify callback (no more inotify-thread
  stall on burst) + spawn_blocking around try_reload (no more tokio
  executor stall on ONNX load)
- http/fusion: truncated flag now reflects real overflow, not
  matches.len() == cap
- http/soar: reject empty sources[] in dry-run instead of synthesising
  an inconsistent active_source_count=1 event
- detection/attack_type: port_scan now maps to CanonicalAttackType::PortScan
  across ML / Correlation / Suricata so cross-source fusion fires
- detection/orchestrator: full-scan cleanup_expired, since LRU order
  reflects access time not insertion time
- soar/actions: block_ip/unblock_ip via spawn_blocking so parking_lot
  + aya syscalls never run on a tokio worker
- ml/flow_tracker: fwd/bwd total bytes use packet_length (full IP),
  matching user intuition and on-wire byte counts
- ebpf/xsk_manager: userspace DNS-blacklist drops now update DropMonitor;
  TX drop accounting uses nb_submitted so ring backpressure is counted
- config_service: scrub plaintext smtp_password on SecretStore write
- utils/logging: preserve RUST_LOG per-target directives across set_level
- Cargo.toml: let notify auto-select FS backend — previous
  macos_kqueue-only feature meant ModelWatcher silently failed on Linux

Cleanup:
- Remove #[allow(dead_code)] from 9 port traits; delete the genuinely
  dead trait methods + associated Database impl stubs this revealed
- detection/orchestrator: MAX_DEDUP_ENTRIES becomes const NonZero;
  tuple-style log! constructors per CODE_STYLE
- model/system/health: drop unused is_healthy + task-ref comment
- observability/log_buffer: document why parking_lot::Mutex is required
- http/model_upload: module doc now correctly describes PromoteGate as
  AtomicBool reject-not-queue (not a mutex)

All 289 tests pass; cargo clippy --tests -- -D warnings clean.

NetGuardia

Project Overview

NetGuardia is a high-performance network security solution that combines eBPF XDP technology with deep learning models to provide advanced network protection. The system operates as a standalone network appliance that can run on any Ubuntu-based system with compatible network hardware.

Core Technologies

  • eBPF XDP Technology - Provides high-performance packet processing directly at the data link layer
  • Deep Learning Models - Identifies and predicts potential network attacks with intelligent threat detection
  • Hardware Integration - Designed to work with Intel i350 T2 and similar enterprise-grade network interface cards

Functional Modules

Resource Overview

Home

  • Real-time control system occupancy rate

Dashboard Overview

Dashboard

  • Real-time network traffic monitoring and visualization
  • Recent traffic statistics and trend analysis

Detailed Traffic Statistics

Statistics

  • Detailed traffic usage information per IP address

Network Access Control

accessControl

  • IPv4/IPv6 whitelist and blacklist management
  • Precise port-level access control

System Features

  • High Performance - Low-latency packet processing with minimal network performance impact
  • User-Friendly - Cross-platform web management interface with intuitive operation
  • Reliability - Hardware-accelerated processing ensures stable operation
  • Scalability - Modular design supports functional expansion

System Requirements

NetGuardia requires the combination of a kernel with eBPF support and a NIC driver that implements AF_XDP on that kernel. There is no single "minimum kernel version" — it depends on which NIC driver you use.

  • Linux with eBPF + AF_XDP support for your NIC driver. Any modern distribution (Ubuntu 22.04+, Debian 12+, RHEL 9+, Fedora recent) is fine as long as the driver matrix below lines up.
  • Dual-port NIC with an AF_XDP-capable driver (see matrix).
  • Root / sudo access for eBPF program loading.

NIC driver / kernel matrix (AF_XDP)

Driver NIC family (examples) Min kernel for AF_XDP
mlx5 Mellanox ConnectX-4/5/6/7 5.x (early)
ixgbe Intel 82599, X520, X540, X550 5.x
i40e Intel X710, XL710, XXV710 5.x
ice Intel E810 5.5+
igb Intel i350 T2 (reference hardware) 6.17
igc Intel I225/I226 6.x
virtio_net QEMU/KVM virtual NICs varies; AF_XDP is limited

If you are using the reference Intel i350 T2, you need Linux 6.17 or newer because igb AF_XDP support landed in that release. On a kernel older than 6.17 the system will still build, but ingress/egress setup will fail at runtime when AF_XDP binding is attempted — check driver support with ethtool -i <iface> and confirm against the matrix above before deploying.

Hardware Compatibility

  • Network Interface: dual-port NIC with an AF_XDP-capable driver on your kernel (see matrix above). Intel i350 T2 is the reference hardware.
  • CPU: multi-core recommended; XDP scales with RX queue count.
  • Memory: 8 GB minimum, 16 GB+ for high-traffic environments.

NetGuardia is not limited to embedded platforms — it runs on standard server hardware, virtual machines, or dedicated appliances as long as the driver/kernel requirement above is met.
