macOS platform:
- Platform-native TUN interface management with shutdown pipe
- Raw Ethernet transport with macOS socket backend (socket_macos.rs)
- EthernetTransport and TransportHandle::Ethernet ungated from Linux-only
- macOS .pkg packaging (build-pkg.sh, launchd plist, uninstall script)
- CI: macOS build and unit test jobs; x86_64 cross-compiled from
macos-latest via rustup target add x86_64-apple-darwin
Gateway feature flag:
- New opt-in `gateway` Cargo feature activates optional `rustables` dep
- `pub mod gateway` and `Config.gateway` gated behind the feature so
macOS builds never pull in Linux-only nftables bindings
- `fips-gateway` bin has `required-features = ["gateway"]`
- All Linux/OpenWrt/AUR packaging passes `--features gateway`
CI / packaging:
- package-linux, package-macos, package-openwrt now trigger on push to
master/maint/next and on pull requests; release uploads remain tag-gated
- Bloom filter routing fix: fall through to tree routing when no candidate
is strictly closer
- MMP intervals: raise MIN to 1s / MAX to 5s with 5-sample cold-start phase
Add TorTransport in src/transport/tor/ supporting three operating modes:
Outbound (socks5 mode):
- Non-blocking SOCKS5 connect via tokio-socks with per-destination
circuit isolation (IsolateSOCKSAuth)
- TorAddr enum for .onion and clearnet address types
- Connection pool with per-connection receive tasks, reuses TCP
stream FMP framing
- connect_async()/connection_state_sync()/promote_connection() follow
the same non-blocking polling pattern as TCP transport
Inbound (directory mode — recommended for production):
- Tor manages the onion service via HiddenServiceDir in torrc
- FIPS reads .onion address from hostname file at startup
- No control port needed — enables Tor Sandbox 1 (seccomp-bpf)
- Accept loop mirrors TCP pattern with DirectoryServiceConfig
Monitoring (control_port mode and optional in directory mode):
- Async control port client supporting TCP and Unix socket connections
via Box<dyn AsyncRead/Write> trait objects
- AUTHENTICATE with cookie or password auth
- 8 GETINFO queries: bootstrap, circuits, traffic, liveness, version,
dormant state, SOCKS listeners
- Background monitoring task polls every 10s, caches TorMonitoringInfo
in Arc<RwLock> for synchronous query access
- Bootstrap milestone logging (25/50/75/100%), stall warning (>60s),
network liveness transitions, dormant mode entry
- Directory mode optionally connects to control port when control_addr
is configured (non-fatal on failure)
Operator visibility:
- show_transports query exposes tor_mode, onion_address, tor_monitoring
(bootstrap, circuit_established, traffic, liveness, version, dormant)
- fipstop transport detail view: Tor mode, onion address, SOCKS5/control
errors, connection stats, Tor daemon status section
- fipstop table view: tor(mode) label with truncated onion address hint
Security hardening:
- Per-destination circuit isolation via IsolateSOCKSAuth
- Unix socket default for control port (/run/tor/control)
- Reference torrc with HiddenServiceDir, VanguardsLiteEnabled,
ConnectionPadding, DoS protections (PoW + intro rate limiting)
Config:
- TorConfig with socks5, control_port, and directory modes
- DirectoryServiceConfig: hostname_file, bind_addr
- control_addr, control_auth, cookie_path, connect_timeout,
max_inbound_connections
Testing:
- 69 unit + integration tests with mock SOCKS5 and control servers
- Docker tests: socks5-outbound (clearnet via Tor) and directory-mode
(HiddenServiceDir onion service)
Documentation:
- Transport layer design doc: Tor architecture, directory mode
- Configuration doc: Tor config tables and examples
Adds packaging/openwrt/ with everything needed to produce and distribute
FIPS .ipk packages for OpenWrt routers:
- Makefile: OpenWrt feed package definition using rust/host toolchain,
maps OpenWrt ARCH to Rust musl target triples
- build-ipk.sh: local build script using cargo-zigbuild + direct tar
assembly — no OpenWrt SDK or Docker required. Handles macOS BSD tar
(ustar format, resource fork suppression) and portable ar header
generation for cross-platform .ipk creation. Accepts PKG_VERSION
env var override for CI use.
- files/: procd init script, default fips.yaml (persistent identity,
br-lan and wwan interface examples), firewall helper, dnsmasq .fips
forwarding, br_netfilter sysctl, hotplug for fips0, UCI defaults for
first-boot setup, sysupgrade keeplist
- .github/workflows/package-openwrt.yml: CI workflow (ubuntu-latest +
cargo-zigbuild) building aarch64 and x86_64 .ipk packages using
build-ipk.sh; llvm-strip for cross-compiled binaries; triggers on
every push; publishes to GitHub Releases on version tags. MIPS
targets disabled pending portable-atomic crate (32-bit MIPS lacks
native AtomicU64), with nightly/rust-src toolchain steps prepared
for re-enablement.
- .gitignore: add reference/, dist/, *.ipk
- Ethernet ioctl: cfg-gate the ioctl request parameter type — c_int on
musl, c_ulong on gnu — so the same code compiles on both
x86_64-unknown-linux-gnu and x86_64-unknown-linux-musl targets
- Chaos harness macOS support: replace direct host 'ip link' invocations
with a privileged Docker container helper (--net=host --pid=host) that
shares the Docker VM's namespaces, making veth pair setup work on both
Linux and macOS (where host 'ip' is unavailable and container PIDs
live inside the Docker Desktop VM)
- Python 3.9 compat: add 'from __future__ import annotations' to
docker_exec.py for X|Y union syntax support
- Add deploy/ to .gitignore

Implements FIPS Identity System (Section 1 of design doc):
- NodeId: 32-byte SHA-256 hash of npub, with Ord for root election
- FipsAddress: 128-bit IPv6-compatible address (0xfd prefix)
- Identity: keypair holder with sign/verify methods
- AuthChallenge/AuthResponse: challenge-response authentication
All 11 tests passing.
