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.
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 fips-gateway binary to CI artifact and Docker build. Systemd
service unit with After=fips.service dependency and security
hardening. Debian and AUR package entries.
OpenWrt packaging: procd init script managing dnsmasq forwarding,
proxy NDP, RA route advertisements for the virtual IP pool, and a
global IPv6 prefix on br-lan to work around Android suppressing AAAA
queries on ULA-only networks. Sysctl config for IPv6 forwarding.
Gateway enabled by default in OpenWrt config. Ethernet transport
enabled by default.
Default gateway config section (commented out) in common fips.yaml.
Add a complete example running a strfry Nostr relay exclusively over
the FIPS mesh using the sidecar pattern. Includes Docker Compose
stack, network isolation via iptables, .fips DNS resolution, nak CLI,
build script with cross-compilation support, and documentation.
Also fix the package-openwrt.yml workflow path to match the
openwrt → openwrt-ipk directory rename.
