Gate platform-specific code behind cfg attributes and add full Windows
support: TUN device via wintun, TCP control socket on localhost:21210,
Windows Service lifecycle (--install-service/--uninstall-service/--service),
CI build and test matrix, and packaging with ZIP builder and PowerShell
service management scripts.
Key changes:
- Cargo.toml: move tun/libc/rtnetlink behind cfg(unix); add wintun and
windows-service dependencies for Windows
- upper/tun.rs: wintun-based TUN implementation with netsh configuration
for IPv6 address, MTU, and fd00::/8 routing
- control/mod.rs: split into unix_impl/windows_impl; Windows uses TCP on
localhost:21210 with shared connection handler
- bin/fips.rs: refactor main() into run_daemon() accepting a shutdown
signal; add Windows Service support via windows-service crate
- transport/udp/socket.rs: platform-gated modules; Windows uses
tokio::net::UdpSocket (kernel drop count unavailable, returns 0)
- transport/ethernet: gate to cfg(unix); add Windows stub types
- config: platform-conditional default paths (socket, hosts) for Windows
- CI: add windows-latest to build matrix and test-windows job with
cargo-nextest
- packaging/windows: build-zip.ps1, install-service.ps1,
uninstall-service.ps1, and package-windows.yml workflow
- README/docs: Windows build instructions, service management, and
control socket platform differences
Linux and macOS behavior is unchanged.
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.
