Backend scaffolding for the admin model-upload UI. Accepts `manifest`
(YAML) + `onnx` (binary) multipart fields, streams each directly to a
fresh `models/.staging/<uuid>/` directory with enforced size caps, and
sanity-checks the ONNX header before ever touching disk. Structural
schema validation against `MLInferenceConfig` — plus the atomic
promote-to-`models/` step — is the next milestone's job; this commit
lands only the upload / staging surface.
New file `adapter/http/model_upload.rs`:
- `POST /api/ml/models/upload` scoped under `/api/ml/models`. Returns
`{ staging_id, manifest_bytes, onnx_bytes, onnx_filename }` on
success.
- Streams per-field, never buffers the full `.onnx` in RAM. Per-field
byte cap enforced inline: 100 MB for onnx, 64 KB for manifest.
Overflow yields 413 and the staging subdir is torn down before the
response returns.
- `looks_like_onnx` heuristic rejects empty, all-zero, all-printable,
and common container magics (ZIP, PNG, PDF, ELF) up front. Positive
acceptance is handled authoritatively later by tract during
`build_adapter`.
- `sanitize_filename` keeps the client's suffix but strips traversal
so the staging dir can never escape.
- `clean_staging_orphans(root, max_age)` sweeps leftover subdirs;
reused at startup and available for a periodic task later.
Wiring:
- `actix-multipart = "0.7"` and `uuid` (with `v4`) added to
`net-guardia/Cargo.toml`.
- `system.rs` calls `clean_staging_orphans` once during `run()` before
the model watcher starts listening, with a 1 h age threshold. Two
new `SystemLog` variants (`StagingOrphansCleaned` /
`StagingOrphansSweepFailed`) report results.
- `http_server.rs` registers the new scope inside the existing
`/api` scope. CSRF / JWT middleware already covers the route; no
permission table changes needed beyond what I-11 provides.
Tests: 10 new (5 ONNX-sniff edge cases — empty / zero-padded / plain
text / varint tag / length-delimited tag; 3 `sanitize_filename`
cases; 2 orphan-sweep cases including the no-staging-dir short
circuit). 240 pass total. clippy --package net-guardia -- -D warnings
clean.
Closes I-region I-12.

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
- Real-time control system occupancy rate
Dashboard Overview
- Real-time network traffic monitoring and visualization
- Recent traffic statistics and trend analysis
Detailed Traffic Statistics
- Detailed traffic usage information per IP address
Network Access Control
- 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.
