Replace two-node-udp with Docker network test harness, fix dead code warnings
Replace examples/two-node-udp/ (netns-based) with examples/docker-network/ (Docker compose, 5 nodes, mesh + chain topologies). The new harness uses auto-detecting build script and includes SVG topology diagrams. Remove unused get_session_mut, remote_addr(), remote_pubkey() methods. Gate test-only accessors with #[cfg(test)]. Zero warnings in release build.

# Docker Network Test Harness
|
||||
|
||||
Multi-node integration test for FIPS using Docker containers. Two topologies
|
||||
are provided: a sparse mesh (5 nodes, 6 links) and a linear chain (5 nodes,
|
||||
4 links). Both exercise the full FIPS stack including TUN devices, DNS
|
||||
resolution, peer link encryption, spanning tree construction, and
|
||||
discovery-driven multi-hop routing.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Docker with the compose plugin
|
||||
- Rust toolchain (for building the FIPS binary)
|
||||
|
||||
## Quick Start
|
||||
|
||||
Build the binary and copy it to the docker context:
|
||||
|
||||
```bash
|
||||
./scripts/build.sh
|
||||
```
|
||||
|
||||
### Mesh Topology
|
||||
|
||||
```bash
|
||||
docker compose --profile mesh build
|
||||
docker compose --profile mesh up -d
|
||||
./scripts/ping-test.sh mesh # 20/20 expected
|
||||
docker compose --profile mesh down
|
||||
```
|
||||
|
||||
### Chain Topology
|
||||
|
||||
```bash
|
||||
docker compose --profile chain build
|
||||
docker compose --profile chain up -d
|
||||
./scripts/ping-test.sh chain # 6/6 expected
|
||||
docker compose --profile chain down
|
||||
```
|
||||
|
||||
## Mesh Topology
|
||||
|
||||
|
||||
|
||||
Five nodes with 6 bidirectional UDP links forming a sparse, fully connected
|
||||
graph. Not all nodes are direct peers — non-adjacent pairs require
|
||||
discovery-driven multi-hop routing to establish end-to-end sessions.
|
||||
|
||||
The spanning tree is rooted at node A, which has the lexicographically
|
||||
smallest `NodeAddr` (the first 16 bytes of `SHA-256(pubkey)`). Tree edges
|
||||
are highlighted in blue in the diagram above.
|
||||
|
||||
The ping test exercises all 20 directed pairs (5 nodes x 4 targets each),
|
||||
covering both direct-peer and multi-hop paths.
|
||||
|
||||
| Link | Type |
|
||||
|------|------|
|
||||
| A — D | tree edge (D's parent is A) |
|
||||
| A — E | tree edge (E's parent is A) |
|
||||
| C — D | tree edge (C's parent is D) |
|
||||
| B — C | tree edge (B's parent is C) |
|
||||
| D — E | non-tree link |
|
||||
| C — E | non-tree link |
|
||||
|
||||
## Chain Topology
|
||||
|
||||
|
||||
|
||||
Five nodes in a linear chain: A — B — C — D — E. Each node peers only with
|
||||
its immediate neighbors. Multi-hop communication (e.g., A to E) requires the
|
||||
discovery protocol to find routes through intermediate nodes.
|
||||
|
||||
The ping test covers:
|
||||
|
||||
- Adjacent hops: A→B, B→C (1 hop each)
|
||||
- Multi-hop: A→C (2 hops), A→D (3 hops), A→E (4 hops)
|
||||
- Reverse: E→A (4 hops)
|
||||
|
||||
## Node Identities
|
||||
|
||||
All nodes use deterministic test keys (not for production use).
|
||||
|
||||
| Node | npub | FIPS IPv6 Address | Docker IP |
|
||||
|------|------|-------------------|-----------|
|
||||
| A | `npub1sjlh2c3...` | `fd69:e08d:65cc:3a6b:...` | 172.20.0.10 |
|
||||
| B | `npub1tdwa4vj...` | `fd8e:302c:287e:b48d:...` | 172.20.0.11 |
|
||||
| C | `npub1cld9yay...` | `fdac:a221:4069:5044:...` | 172.20.0.12 |
|
||||
| D | `npub1n9lpnv0...` | `fdb6:8411:a191:6d48:...` | 172.20.0.13 |
|
||||
| E | `npub1wf8akf8...` | `fded:7dee:d386:a546:...` | 172.20.0.14 |
|
||||
|
||||
## Container Configuration
|
||||
|
||||
- **Base image**: debian:bookworm-slim
|
||||
- **Capabilities**: `CAP_NET_ADMIN` (for TUN device creation)
|
||||
- **Devices**: `/dev/net/tun` mapped into each container
|
||||
- **DNS**: FIPS built-in resolver on `127.0.0.1:53`
|
||||
- **Transport**: UDP on port 4000, MTU 1280
|
||||
- **TUN**: `fips0` interface, MTU 1280
|
||||
|
||||
Each node resolves `<npub>.fips` DNS names to FIPS IPv6 addresses via its
|
||||
local DNS responder, which primes the identity cache for session establishment.
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
**Stale images after code changes**: Docker compose may cache old layers.
|
||||
Force a clean rebuild:
|
||||
|
||||
```bash
|
||||
docker compose --profile mesh build --no-cache
|
||||
```
|
||||
|
||||
**Check node logs**:
|
||||
|
||||
```bash
|
||||
docker logs fips-node-a
|
||||
docker logs -f fips-node-c # follow
|
||||
```
|
||||
|
||||
**Verify DNS resolution inside a container**:
|
||||
|
||||
```bash
|
||||
docker exec fips-node-a dig AAAA npub1tdwa4vjrjl33pcjdpf2t4p027nl86xrx24g4d3avg4vwvayr3g8qhd84le.fips @127.0.0.1
|
||||
```
|
||||
|
||||
**Verify binary is up to date**: Compare hashes between the local build and
|
||||
the binary inside the container:
|
||||
|
||||
```bash
|
||||
md5sum examples/docker-network/fips
|
||||
docker exec fips-node-a md5sum /usr/local/bin/fips
|
||||
```
|
||||
|
||||
**Increase convergence time**: If tests fail intermittently, the 5-second
|
||||
convergence wait in `ping-test.sh` may be insufficient. Edit the `sleep`
|
||||
value at the top of the script.

# Two-Node UDP Test
|
||||
|
||||
This example demonstrates two FIPS nodes communicating over UDP using Linux
|
||||
network namespaces. Both nodes establish an encrypted peer link, build a
|
||||
spanning tree, and create end-to-end sessions. With TUN and DNS enabled, you
|
||||
can `ping6` between nodes using raw IPv6 addresses.
|
||||
|
||||
## Network Diagram
|
||||
|
||||
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Linux with network namespace support (requires root for namespace setup)
|
||||
- IPv6 enabled (`sysctl net.ipv6.conf.all.disable_ipv6` should be `0`)
|
||||
- `iproute2` tools (`ip`), `dig` (from `dnsutils` or `bind-utils`)
|
||||
- Rust toolchain (to build the FIPS binary)
|
||||
|
||||
## Node Identities
|
||||
|
||||
| Node | npub | FIPS Address |
|
||||
|------|------|-------------|
|
||||
| A | `npub1sjlh2c3x9w7kjsqg2ay080n2lff2uvt325vpan33ke34rn8l5jcqawh57m` | `fd69:e08d:65cc:3a6b:9c2c:2ac4:bd40:5e4b` |
|
||||
| B | `npub1tdwa4vjrjl33pcjdpf2t4p027nl86xrx24g4d3avg4vwvayr3g8qhd84le` | `fd8e:302c:287e:b48d:6268:122f:da76:b77` |
|
||||
|
||||
## Step 1: Build FIPS
|
||||
|
||||
From the FIPS source root:
|
||||
|
||||
```bash
|
||||
cargo build
|
||||
```
|
||||
|
||||
The binary will be at `target/debug/fips`. Note the absolute path — you'll
|
||||
need it when running inside namespaces.
|
||||
|
||||
## Step 2: Create Network Namespaces
|
||||
|
||||
This creates two namespaces (`fips-a` and `fips-b`) connected by a virtual
|
||||
ethernet pair. Each namespace has its own isolated network stack, including
|
||||
its own routing table, TUN devices, and DNS resolver.
|
||||
|
||||
```bash
|
||||
# Create namespaces
|
||||
sudo ip netns add fips-a
|
||||
sudo ip netns add fips-b
|
||||
|
||||
# Create a veth pair connecting them
|
||||
sudo ip link add veth-a type veth peer name veth-b
|
||||
|
||||
# Move each end into its namespace
|
||||
sudo ip link set veth-a netns fips-a
|
||||
sudo ip link set veth-b netns fips-b
|
||||
|
||||
# Configure IPv4 addresses (used by UDP transport)
|
||||
sudo ip netns exec fips-a ip addr add 10.0.0.1/24 dev veth-a
|
||||
sudo ip netns exec fips-b ip addr add 10.0.0.2/24 dev veth-b
|
||||
|
||||
# Bring interfaces up
|
||||
sudo ip netns exec fips-a ip link set veth-a up
|
||||
sudo ip netns exec fips-b ip link set veth-b up
|
||||
|
||||
# Enable loopback in both (needed for DNS responder on 127.0.0.1)
|
||||
sudo ip netns exec fips-a ip link set lo up
|
||||
sudo ip netns exec fips-b ip link set lo up
|
||||
|
||||
# Enable IPv6 in both namespaces
|
||||
sudo ip netns exec fips-a sysctl -w net.ipv6.conf.all.disable_ipv6=0
|
||||
sudo ip netns exec fips-b sysctl -w net.ipv6.conf.all.disable_ipv6=0
|
||||
```
|
||||
|
||||
Verify connectivity between namespaces:
|
||||
|
||||
```bash
|
||||
sudo ip netns exec fips-a ping -c 1 10.0.0.2
|
||||
```
|
||||
|
||||
## Step 3: Start Node A
|
||||
|
||||
Open **Terminal 1**. This runs the FIPS daemon for Node A inside its
|
||||
namespace. The daemon creates a `fips0` TUN device, starts the DNS responder,
|
||||
connects to Node B over UDP, and begins the Noise IK handshake.
|
||||
|
||||
```bash
|
||||
sudo ip netns exec fips-a \
|
||||
env RUST_LOG=info \
|
||||
/path/to/target/debug/fips --config /path/to/examples/two-node-udp/fips-a.yaml
|
||||
```
|
||||
|
||||
Replace `/path/to/` with the actual absolute paths to your build and this
|
||||
example directory.
|
||||
|
||||
You should see output like:
|
||||
|
||||
```text
|
||||
INFO fips: FIPS starting
|
||||
INFO fips: Node created:
|
||||
INFO fips: npub: npub1sjlh2c3x9w7kjsqg2ay080n2lff2uvt325vpan33ke34rn8l5jcqawh57m
|
||||
INFO fips: address: fd69:e08d:65cc:3a6b:9c2c:2ac4:bd40:5e4b
|
||||
INFO fips: TUN device active:
|
||||
INFO fips: name: fips0
|
||||
INFO fips: address: fd69:e08d:65cc:3a6b:9c2c:2ac4:bd40:5e4b
|
||||
INFO fips: DNS responder started for .fips domain
|
||||
INFO fips: Peer connection initiated (node-b)
|
||||
```
|
||||
|
||||
## Step 4: Start Node B
|
||||
|
||||
Open **Terminal 2**. Run Node B in its namespace:
|
||||
|
||||
```bash
|
||||
sudo ip netns exec fips-b \
|
||||
env RUST_LOG=info \
|
||||
/path/to/target/debug/fips --config /path/to/examples/two-node-udp/fips-b.yaml
|
||||
```
|
||||
|
||||
Once both nodes are running, you should see handshake completion messages in
|
||||
both terminals:
|
||||
|
||||
```text
|
||||
INFO fips::node::handlers::handshake: Peer promoted to active
|
||||
```
|
||||
|
||||
The spanning tree will converge within a few seconds (TreeAnnounce exchange),
|
||||
followed by bloom filter exchange (FilterAnnounce).
|
||||
|
||||
## Step 5: Test DNS Resolution
|
||||
|
||||
The FIPS daemon includes a DNS responder that resolves `<npub>.fips` queries
|
||||
to FIPS IPv6 addresses. Open **Terminal 3** to test it.
|
||||
|
||||
Query the DNS responder directly with `dig`:
|
||||
|
||||
```bash
|
||||
# From Node A, resolve Node B's name
|
||||
sudo ip netns exec fips-a dig @127.0.0.1 -p 5354 AAAA \
|
||||
npub1tdwa4vjrjl33pcjdpf2t4p027nl86xrx24g4d3avg4vwvayr3g8qhd84le.fips
|
||||

# Expected answer: fd8e:302c:287e:b48d:6268:122f:da76:b77
|
||||
```
|
||||
|
||||
Watch Terminal 1 — you should see a log line (requires `RUST_LOG=debug`):
|
||||
|
||||
```text
|
||||
DEBUG fips::dns: DNS resolved .fips name, registering identity
|
||||
```
|
||||
|
||||
This confirms the identity cache was populated. The subsequent ping will be
|
||||
able to route through the mesh.
|
||||
|
||||
> **Note:** `resolvectl` and system resolver integration (e.g., `ping6
|
||||
> npub1...fips`) do not work inside network namespaces because
|
||||
> `systemd-resolved` runs in the host namespace and is not accessible from
|
||||
> within isolated namespaces. Use `dig @127.0.0.1 -p 5354` to query the
|
||||
> DNS responder directly, and use raw IPv6 addresses for `ping6`. System
|
||||
> resolver integration works when FIPS runs in the host namespace or with
|
||||
> the future D-Bus auto-registration (Phase 2).
|
||||
|
||||
## Step 6: Ping Between Nodes
|
||||
|
||||
Now test end-to-end connectivity. The first ping triggers session
|
||||
establishment (Noise IK handshake through the mesh), so it may take a moment
|
||||
longer than subsequent pings.
|
||||
|
||||
### Ping Node B from Node A
|
||||
|
||||
From Terminal 3:
|
||||
|
||||
```bash
|
||||
sudo ip netns exec fips-a ping6 -c 4 fd8e:302c:287e:b48d:6268:122f:da76:b77
|
||||
```
|
||||
|
||||
### Ping Node A from Node B
|
||||
|
||||
```bash
|
||||
sudo ip netns exec fips-b ping6 -c 4 fd69:e08d:65cc:3a6b:9c2c:2ac4:bd40:5e4b
|
||||
```
|
||||
|
||||
Ping replies are handled by the kernel's IPv6 stack — when a ping arrives
|
||||
at the destination's TUN device, the kernel sees it addressed to its own
|
||||
`fips0` address and replies natively. FIPS handles the encrypted transport
|
||||
between nodes; the kernel handles ICMPv6 Echo Reply.
|
||||
|
||||
## Step 7: Watch the Logs
|
||||
|
||||
While pinging, watch the daemon terminals for the protocol flow:
|
||||
|
||||
1. **DNS resolution** — `DNS resolved .fips name, registering identity`
|
||||
2. **TUN packet** — `TUN packet received` with src/dst addresses
|
||||
3. **Session initiation** — `Initiating session to <node_addr>`
|
||||
4. **SessionSetup sent** — Noise IK msg1 sent through mesh
|
||||
5. **SessionSetup received** — Responder processes msg1
|
||||
6. **SessionAck** — Responder sends msg2 back
|
||||
7. **Session established** — Both sides transition to Established
|
||||
8. **DataPacket** — Encrypted IPv6 payload delivered
|
||||
|
||||
Set `RUST_LOG=debug` for the full protocol trace, or `RUST_LOG=info` for
|
||||
high-level events only.
|
||||
|
||||
## Cleanup
|
||||
|
||||
Stop both FIPS daemons with Ctrl+C in Terminals 1 and 2. Then tear down
|
||||
the namespaces:
|
||||
|
||||
```bash
|
||||
sudo ip netns delete fips-a
|
||||
sudo ip netns delete fips-b
|
||||
```
|
||||
|
||||
This also removes the veth pair and TUN devices automatically.
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### "Permission denied" creating TUN device
|
||||
|
||||
The FIPS binary needs `CAP_NET_ADMIN` to create TUN devices. Running via
|
||||
`sudo ip netns exec` already provides root privileges. If running outside
|
||||
a namespace, use:
|
||||
|
||||
```bash
|
||||
sudo setcap cap_net_admin+ep /path/to/target/debug/fips
|
||||
```
|
||||
|
||||
### "Address already in use" on DNS port
|
||||
|
||||
Another process is using port 5354. Change the `dns.port` in the YAML config
|
||||
to a different port (e.g., 5355).
|
||||
|
||||
### No handshake completion
|
||||
|
||||
Check that the veth pair is up and the namespaces can reach each other:
|
||||
|
||||
```bash
|
||||
sudo ip netns exec fips-a ping -c 1 10.0.0.2
|
||||
```
|
||||
|
||||
If this fails, the namespace setup is incomplete.
|
||||
|
||||
### IPv6 disabled
|
||||
|
||||
```bash
|
||||
sudo ip netns exec fips-a sysctl net.ipv6.conf.all.disable_ipv6
|
||||
# Should be 0
|
||||
```
|
||||
|
||||
### DNS query returns no answer
|
||||
|
||||
Verify the DNS responder is running by querying it directly:
|
||||
|
||||
```bash
|
||||
sudo ip netns exec fips-a dig @127.0.0.1 -p 5354 AAAA \
|
||||
npub1tdwa4vjrjl33pcjdpf2t4p027nl86xrx24g4d3avg4vwvayr3g8qhd84le.fips
|
||||
```
|
||||
|
||||
If `dig` works but `resolvectl query` or `ping6 <npub>.fips` doesn't,
|
||||
this is expected — `systemd-resolved` runs in the host namespace and is
|
||||
not accessible from inside network namespaces. Use raw IPv6 addresses
|
||||
for testing within namespaces.
