BLE transport implementation using L2CAP Connection-Oriented Channels (SeqPacket mode) via the bluer crate, behind cfg(feature = "ble"). Core transport: - BleTransport<I> generic over BleIo trait (BluerIo prod, MockBleIo test) - Connection pool with priority eviction (static > discovered, max 7) - Connect-on-send via connect_inline() matching TCP behavior - Per-connection receive loops with pool cleanup on disconnect Discovery and probing: - Combined scan_probe_loop using select! over scanner events and a BinaryHeap delay queue with per-entry random jitter (0-5s) to prevent herd effects when multiple nodes see the same beacon simultaneously - Pre-handshake pubkey exchange ([0x00][pubkey:32]) for IK identity - Cross-probe tie-breaker: smaller NodeAddr's outbound wins (same convention as FMP/FSP rekey dual-initiation) - Probed peers reported to DiscoveryBuffer; pool fills through normal node-layer auto-connect -> send_async -> connect_inline path Beacon management: - Periodic advertising: 1s burst every 30s (configurable via beacon_interval_secs / beacon_duration_secs) - FIPS service UUID for scan filtering Configuration (all fields optional with defaults): - adapter, psm, mtu, max_connections, connect_timeout_ms - advertise, scan, auto_connect, accept_connections - beacon_interval_secs (30), beacon_duration_secs (1) Hardware validated with two BLE nodes: - 2048-byte MTU, ~60-160ms RTT, zero-config auto-connect - BLE spike tool at testing/ble/ for standalone adapter validation 42 unit tests + 4 node-level integration tests, all CI-compatible via MockBleIo (no hardware required). tokio test-util added for time-dependent scan/probe tests.
FIPS Packaging
This directory contains packaging for all supported target platforms.
All build outputs go to deploy/ at the project root.
Quick Start
make deb # Debian/Ubuntu .deb
make tarball # systemd install tarball
make ipk # OpenWrt .ipk
make aur # Arch Linux AUR package (fips-git, local build + namcap)
make all # deb + tarball (default)
Directory Structure
packaging/
aur/ Arch Linux AUR packaging (PKGBUILD, supporting files)
common/ Shared assets (default config, hosts file)
debian/ Debian/Ubuntu .deb packaging via cargo-deb
systemd/ Generic Linux systemd tarball packaging
openwrt/ OpenWrt .ipk packaging via cargo-zigbuild
Formats
Debian/Ubuntu (.deb)
Built with cargo-deb. Installs
fips, fipsctl, and fipstop to /usr/bin/, places config at
/etc/fips/fips.yaml (preserved on upgrade), and enables the systemd
service.
# Build
make deb
# Install
sudo dpkg -i deploy/fips_<version>_<arch>.deb
# Remove (preserves config and keys)
sudo dpkg -r fips
# Purge (removes config and identity keys)
sudo dpkg -P fips
systemd Tarball
A self-contained tarball with binaries and an install.sh script for
any systemd-based Linux distribution.
# Build
make tarball
# Install (on target host)
tar -xzf deploy/fips-<version>-linux-<arch>.tar.gz
sudo ./fips-<version>-linux-<arch>/install.sh
See systemd/README.install.md for full installation and configuration instructions.
OpenWrt (.ipk)
Cross-compiled with cargo-zigbuild and assembled as a standard .ipk
archive. Supports aarch64, mipsel, mips, arm, and x86_64 targets.
# Build (default: aarch64)
make ipk
# Build for a specific architecture
bash packaging/openwrt/build-ipk.sh --arch mipsel
See openwrt/README.md for router-specific installation instructions.
Arch Linux (AUR)
Two AUR packages are maintained: fips (release, builds from tagged
tarball) and fips-git (development, builds from latest git master).
# Build and validate locally (git variant)
make aur
# Install from AUR
yay -S fips-git # development build from master
yay -S fips # release build from latest tag
See aur/README.md for AUR publication instructions and maintainer guide.
Shared Assets
common/ contains assets used across packaging formats:
fips.yaml— default configuration (ephemeral identity, UDP/TCP/TUN/DNS)hosts— static hostname-to-npub mappings for.fipsDNS resolution
