Johnathan Corgan	e641eb5b5f	Drop the nostr-discovery cargo feature flag ... Make Nostr-mediated overlay discovery unconditional, mirroring the philosophy of PR #79's collapse of the tui/ble/gateway features in favor of platform cfg gates. nostr / nostr-sdk are pure Rust over WebSockets/TCP, so they build cleanly on every FIPS-supported platform — there is no need for the parallel feature gate. The flag was already in `default = [...]`, so no behavior change for anyone using `cargo build` without `--no-default-features`. Operators who explicitly disabled the feature will now find Nostr code present in the binary; the runtime check `node.discovery.nostr.enabled` still controls whether the runtime starts. Cargo.toml: - Remove the `[features]` table entirely. - Drop `optional = true` from `nostr` and `nostr-sdk`. Source: 27 cfg sites collapsed across 5 files — `src/discovery.rs`, `src/discovery/nostr/mod.rs`, `src/node/handlers/rx_loop.rs`, `src/node/lifecycle.rs`, `src/node/mod.rs`. Two `#[cfg(not(feature = "nostr-discovery"))]` fallback blocks (the udp:nat-without-runtime debug-log path and the "feature not compiled in" warning at startup) were removed as dead code; the always-on path already handles the missing-runtime case via `nostr_discovery: Option<NostrDiscovery>`. Packaging and tooling: - `packaging/openwrt-ipk/Makefile`: drop a stale `--features gateway` flag (the `gateway` feature was already removed in PR #79; this was a leftover that the build path tolerated only because cargo ignored unknown feature names). - `testing/scripts/build.sh`: drop `DEFAULT_CARGO_BUILD_ARGS=(--features nostr-discovery)`; defaults are empty. - `packaging/common/fips.yaml`: drop the "requires the nostr-discovery feature" comment from the discovery section. Bundled cleanup: - Apply `cargo clippy --fix` against three pre-existing warnings in `src/discovery/nostr/runtime.rs` and `src/discovery/nostr/stun.rs` (collapsed `if let Some` chain; two redundant `as i32` casts). These were always present but masked when the feature gate was off; they surface now that the code is unconditionally compiled. - `cargo fmt` settled two minor formatting drift sites in `src/bin/fips-gateway.rs` and `src/config/mod.rs`. Tests: 1083 passed, 0 failed, 4 ignored. clippy clean. fmt clean.	2026-04-30 10:24:32 +00:00
Johnathan Corgan	37c2973e2f	Test infrastructure overhaul: gateway robustness + full CI coverage ... Single combined commit covering five interlocking pieces of test and CI work that landed during the v0.3.0-prep cycle. ## fips-gateway robustness - src/bin/fips-gateway.rs DNS upstream probe converted from a 3-second hard-fail to a bounded retry loop (5 attempts × 1s timeout, 1s sleep between attempts; ~10s worst case). Covers the cold-boot race where the daemon's TUN is up but the DNS responder at [::1]:5354 is still binding. Each failed attempt logs at INFO. In production the binary's retry is the live recovery mechanism; with retry it recovers silently instead of relying on Restart=on-failure (~5s blip + spurious ERROR per cycle). - packaging/debian/fips-gateway.service `ExecStartPre` now waits up to 30 seconds for the daemon's `fips0` TUN to appear before exec'ing the gateway binary. Eliminates the cold-boot race where the gateway exits with `fips0 interface not found` and recovers via `Restart=on-failure`, producing a 5-second blip and a spurious error log per restart cycle. - testing/docker/entrypoint.sh gateway-mode waits up to 30s for the daemon's DNS responder to bind [::1]:5354 (probes once per second with `dig @::1 -p 5354 ... test.fips`) before exec'ing fips-gateway. Belt-and-suspenders with the binary's own retry: in CI we want deterministic startup ordering. On timeout, fall through so the binary's probe reports the definitive error. ## Test infrastructure DNS bind migration to ::1 After session 359's daemon DNS-bind default flipped from `127.0.0.1` to `::1` (the production fix for ISSUE-2026-0002), the static-test infrastructure was carrying a stale workaround that overrode the default back to IPv4 loopback. The fips-gateway integration test exposed the divergence: the gateway probes its DNS upstream at `[::1]:5354` (production default) while the daemon was binding `127.0.0.1:5354` from the template override — IPv6-explicit sockets do not accept v4-mapped traffic, so the upstream probe exhausted retries and the gateway exited. - Drop the explicit `bind_addr: "127.0.0.1"` line from every test config that emits it: testing/static/configs/node.template.yaml, testing/chaos/configs/node.template.yaml, the sidecar heredoc in testing/docker/entrypoint.sh, testing/acl-allowlist/generate-configs.sh (six per-node blocks), testing/nat/scripts/generate-configs.sh, and the four tor templates under testing/tor/. Daemon picks up its production `::1` default. - Flip the dnsmasq forwarder for `.fips` in testing/docker/Dockerfile from `127.0.0.1#5354` to `::1#5354` so dnsmasq on the shared test image continues to reach the daemon. Template and Dockerfile must move together since most static suites resolve `<npub>.fips` via the test-image dnsmasq. ## rekey-accept-off integration variant + UDP unit test - New `rekey-accept-off` topology and docker-compose profile under testing/static/. 2-node variant where node-b runs with `udp.accept_connections: false`. Pins the regression class that ISSUE-2026-0004 fixed (cross-connection winner's rekey msg1 was being filtered by the accept_connections gate, breaking rekey). - testing/static/scripts/rekey-test.sh accepts REKEY_TOPOLOGY and REKEY_ACCEPT_OFF_NODES env vars; its inject-config subcommand applies the per-node `udp.accept_connections: false` edit, and the test asserts no sustained "Dual rekey initiation" log lines. - New UDP variant of `should_admit_msg1` admit-rekey unit test in src/node/tests/handshake.rs. ## ci-local.sh full integration coverage - New runner functions and dispatcher entries for `acl-allowlist`, `nat-cone` / `nat-symmetric` / `nat-lan`, `rekey-accept-off`, `dns-resolver`, `deb-install`. Each integrates with the existing summary tracking via `record`. - New `--with-tor` flag (off by default) gates `tor-socks5-outbound` and `tor-directory-mode` runners. Tor stays opt-in because both harnesses depend on the live Tor network and would introduce a flake source unrelated to the FIPS code. - New suite arrays (`ACL_SUITES`, `NAT_SUITES`, `DNS_RESOLVER_SUITES`, `DEB_INSTALL_SUITES`, `TOR_SUITES`) drive both the default sweep and `--list` output. - `run_suite` extended to accept the new suite names for `--only` invocations. ## GitHub CI matrix expansions - `gateway` matrix entry runs testing/static/scripts/gateway-test.sh against the existing docker-compose `gateway` profile. - `rekey-accept-off` matrix entry exercises the new topology with REKEY_ACCEPT_OFF_NODES=b. - `deb-install` matrix (debian12 + ubuntu24 + ubuntu26) runs testing/deb-install/test.sh with privileged systemd containers. ~5-7 min cold cache, ~2 min warm per distro. Self-contained: builds its own .deb in a Debian 12 cargo-deb builder image; does not depend on the build job's pre-built artifact. - `dns-resolver` matrix entry runs the full 13-scenario harness (per-distro systemd resolver-backend tests + real-fips end-to-end scenarios) in a single job. Pins the production DNS bind path that ISSUE-2026-0002 lived in. ~7-12 min warm, ~12-15 min cold. Verified locally: full `bash testing/ci-local.sh` sweep passes, including 5/5 deb-install distros and all 13 dns-resolver scenarios. Tor-inclusive sweep (`--with-tor`) verified in a follow-up run.	2026-04-30 10:24:32 +00:00
Johnathan CorganandGitHub	cbc78091ab	Rationalize cargo feature and platform-gate surface (#79) ... Drop the `tui`, `ble`, and `gateway` cargo features and replace them with platform cfg gates. Plain `cargo build` now produces every subsystem appropriate for the target platform with no feature flags required. Motivation: - `default = ["tui", "ble"]` broke `cargo build` on macOS and Windows because `ble` pulled in `bluer` (BlueZ, Linux-only). Every non-Linux packager needed `--no-default-features`. - The feature flags on `ble` and `gateway` were redundant with their platform-gated deps (`bluer`, `rustables`). The parallel gating was inconsistent and error-prone. - `tui` feature protected against a ratatui binary-size concern that no longer applies in 2026. Cargo.toml: - Remove `tui`, `ble`, `gateway` features; `default = []`. - Promote `ratatui` to a non-optional top-level dependency. - Move `rustables` from top-level optional into the Linux target block, non-optional. - Split `bluer` into its own target block with `cfg(all(target_os = "linux", not(target_env = "musl")))` — BlueZ isn't available on musl router targets and `libdbus-sys` doesn't cross-compile to musl without pkg-config sysroot setup. - Drop `required-features` from the `fipstop` and `fips-gateway` `[[bin]]` entries. build.rs: - Emit a `bluer_available` custom cfg when `target_os == "linux"` and `target_env != "musl"`, for use in place of the verbose full predicate in source cfg gates. Source: - Replace every `#[cfg(feature = "gateway")]` with `#[cfg(target_os = "linux")]`. Gateway code works on both glibc and musl Linux (rustables is fine on musl). - Replace every `#[cfg(feature = "ble")]` with `#[cfg(bluer_available)]`. BLE-specific code (BluerIo module, bluer type conversions, BLE transport instance creation, resolve_ble_addr) is excluded on musl and non-Linux. Generic `BleAddr`, `BleIo` trait, `MockBleIo`, and `BleTransport<I>` still compile on all targets. - `src/bin/fips-gateway.rs`: always compiled, but `main()` is gated to Linux. Non-Linux stub exits 1 with a diagnostic. Existing non-Linux packaging scripts don't ship it, so the stub binary sits unused. Packaging and CI: - Drop `--features` and `--no-default-features` flags from every packaging script and workflow. Defaults now match each platform's capabilities. - AUR `fips-git` automatically aligns with stable `PKGBUILD` (both build with defaults). Verified: `cargo build --release` with no flags produces all four binaries on glibc Linux; all unit and integration tests pass across Linux/macOS/Windows/OpenWrt (musl) in CI.	2026-04-24 13:42:30 -07:00
Johnathan Corgan	213c0e87c3	Implement inbound mesh port forwarding ... Mesh peers can now reach a configured host:port on the gateway's LAN via static port-forward rules on fips-gateway. Mirror of the outbound LAN gateway (IDEA-0079 / TASK-2026-0056). Config: new gateway.port_forwards list of { listen_port, proto, target } entries. Targets are SocketAddrV6 — IPv4 is rejected at parse time. Validation rejects zero listen ports and duplicate (listen_port, proto) pairs. NAT: NatManager gains a port_forwards field and set_port_forwards() setter, rebuilt in the same atomic rustables batch as the address mappings. Each forward emits a prerouting DNAT rule keyed on (iifname fips0, nfproto ipv6, l4proto, tcp/udp dport) that rewrites destination address and port via Nat::with_ip_register + with_port_register. When any forwards are configured, a single LAN-side masquerade is installed on (iifname fips0, oifname lan_interface, nfproto ipv6) so the LAN host sees the gateway as source and replies flow back through conntrack. This rule is distinct from the existing oifname fips0 masquerade that serves the outbound pool. Binary: fips-gateway validates port_forwards at startup and calls set_port_forwards after NatManager construction; startup failure cleans up the nftables table before exiting. Test: extend testing/static/scripts/gateway-test.sh with Phase 7 that runs a marker HTTP server on the LAN-side client (fd02::20:8080) and, from the mesh peer, curls the gateway's fips0 address on port 18080 to exercise the full DNAT + LAN masquerade path. The LAN-side HTTP server is started with 'docker exec -d' plus a bind-ready poll on ss; 'docker exec bash -c "cmd &"' does not keep the child alive past the exec session even with nohup. Test-infra: ci-local.sh now builds/clippies/tests with --features gateway, matching GitHub CI. Without this the release fips-gateway binary silently stays stale across runs, since cargo build --release alone does not compile the gateway bin. Verified locally: cargo test --features gateway --lib (991 pass), clippy + fmt clean, full testing/ci-local.sh green (21/21 suites in 8m36s, including the new gateway Phase 7).	2026-04-15 05:04:37 +00:00

Origami74	e693f4fb7e	Add macOS support, fix bloom filter routing and MMP intervals ... 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	2026-04-09 20:03:42 +01:00
Johnathan Corgan	60e5fefb1f	Implement outbound LAN gateway ... Add fips-gateway binary: a separate daemon that allows unmodified LAN hosts to reach FIPS mesh destinations via DNS-allocated virtual IPs and kernel nftables NAT. Gateway DNS resolver: forwarding proxy on [::]:53 that intercepts .fips queries, forwards to daemon resolver (localhost:5354), allocates virtual IPs from pool, returns AAAA records. Always sends AAAA upstream regardless of client query type, returns proper NODATA for non-AAAA. Virtual IP pool: fd01::/112 pool with state machine lifecycle (Allocated → Active → Draining → Free), TTL-based reclamation, conntrack integration for session tracking. NAT manager: nftables DNAT/SNAT rules via rustables netlink API, per-mapping rule lifecycle, fips0 masquerade for LAN client source address rewriting. Network setup: local pool route, proxy NDP for virtual IPs on LAN interface, IPv6 forwarding validation. Control socket at /run/fips/gateway.sock with show_gateway and show_mappings queries. fipstop Gateway tab with pool summary gauge and mappings table. Gateway config section in fips.yaml with pool CIDR, LAN interface, DNS upstream, TTL, and grace period settings. Design doc at docs/design/fips-gateway.md. Integration test (testing/static/scripts/gateway-test.sh): three containers verifying DNS resolution, end-to-end HTTP, NAT state, TTL expiration, SERVFAIL fallback, and clean shutdown.	2026-04-09 16:53:32 +00:00
