The GitHub deb-install matrix ran debian12/ubuntu24/ubuntu26, but the local harness (testing/deb-install/test.sh) runs five distros. Add the missing debian13 (trixie) and ubuntu22 legs so the cloud gate covers the same distro set as local CI. Each new leg invokes the existing test.sh scenario, so per-distro behavior is identical to the local run. Update the granularity-only parity notes in ci.yml, ci-local.sh, and check-ci-parity.sh to list the full distro set.
FIPS Testing
Integration and simulation test harnesses for FIPS, using Docker containers running the full protocol stack.
Test Harnesses
static/ -- Static Docker Network
Fixed topologies with manual scripts for building, config generation, connectivity tests (ping, iperf), and network impairment (netem). Useful for deterministic debugging and validating specific topology configurations.
| Topology | Nodes | Transport | Description |
|---|---|---|---|
| mesh | 5 | UDP | Sparse mesh, 6 links, multi-hop |
| chain | 5 | UDP | Linear chain, max 4-hop paths |
| mesh-public | 5+1 | UDP | Mesh with external public node |
| tcp-chain | 3 | TCP | Linear chain over TCP (port 8443) |
| rekey | 5 | UDP | Rekey integration test topology |
tor/ -- Tor Transport Integration
End-to-end Tor transport testing with Docker containers running real Tor daemons. Requires internet access for Tor bootstrapping.
| Scenario | Description |
|---|---|
| socks5-outbound | Outbound SOCKS5 connections through Tor to clearnet peer |
| directory-mode | Inbound via HiddenServiceDir onion service (co-located) |
nat/ -- NAT Traversal Lab
Real Docker NAT traversal tests for the Nostr/STUN bootstrap path,
using router containers with iptables-based NAT, a local Nostr relay,
and a local STUN responder.
| Scenario | Description |
|---|---|
| cone | Two NATed peers establish a UDP traversal path |
| symmetric | UDP traversal fails under symmetric NAT, TCP fallback wins |
| lan | Peers on the same LAN prefer local addresses over reflexive |
chaos/ -- Stochastic Simulation
Automated network testing with configurable node counts, topology algorithms (random geometric, Erdos-Renyi, chain, explicit), and fault injection (netem mutation, link flaps, traffic generation, node churn). 20 scenarios covering general stress testing, cost-based parent selection, mixed link technologies (fiber/Bluetooth/WiFi), transport-specific validation (UDP, TCP, Ethernet), and ECN/congestion testing. Scenarios are defined in YAML and executed via a Python harness that manages the full lifecycle: topology generation, Docker orchestration, fault scheduling, log collection, and analysis.
interop/ -- Mixed-Version Interop Harness
On-demand harness that runs an N-node full mesh from a node-spec where
each node can run a different build of the FIPS daemon, then attributes
every FMP/FSP/rekey/connectivity failure to a specific version pair
(same-version vs MIXED). Used to catch interop regressions between
builds, not as a per-commit CI gate; not part of ci-local.sh.
mesh-lab/ -- Mesh Reliability Lab
On-demand harness that runs a chosen integration suite N times under a
configurable host-pressure profile (idle / light / github-runner-
equivalent / heavy via stress-ng), per-container netem impairment,
and optional trace-level RUST_LOG, capturing per-rep diagnostics and a
mechanism-match summary across the run. Used for statistical reliability
characterization of known flake classes under calibrated stress, not as
a per-commit gate; not part of ci-local.sh.
