Restructures /docs/ by reader purpose (tutorials, how-to, reference, design), adds the new-user-progression and operator-recipe content the prior layout lacked, runs an accuracy pass against current source across the pre-existing design docs, and rewrites the gateway feature-set documentation end-to-end around its actual operational profile (a niche feature designed for systems already serving DHCP/DNS to a LAN, with two independent halves — outbound LAN→mesh, inbound mesh→LAN — sharing one nftables table, one binary, and one control socket). Top-level README and getting-started rewritten around two equally-weighted deployment modes (overlay on existing IP networks; ground-up over non-IP transports). ## Additions - 11 new tutorials in docs/tutorials/: an 8-step new-user progression from single-daemon test-mesh peering through to a ground-up two-device mesh, an IPv6-adapter side-trip walkthrough, an Advanced Tutorials index, and a hand-held OpenWrt walk-through for fips-gateway deployment that exercises both halves of the feature. - 12 new how-tos in docs/how-to/: firewall activation, Nostr discovery (resolve / advertise / open across five scenarios), Tor onion (directory + control_port modes), UDP buffer tuning, unprivileged-user setup, persistent identity, host aliases, Bluetooth LE peering, MTU diagnostics, manual Linux-host gateway deployment (covers both halves), gateway troubleshooting (organised by half), and a section index. - 9 new reference docs in docs/reference/: configuration, wire formats, control-socket protocol, four CLI references (fips, fipsctl, fipstop, fips-gateway), security posture matrix, and Nostr events catalog. Configuration and wire-formats are renamed-and-extended from prior design/ versions; the other seven are net-new. - 6 new design docs: fips-concepts, fips-architecture, and fips-prior-work split out of the deleted fips-intro.md; consolidated fips-mmp and fips-mtu aggregations; and a new generic port-advertisement-and-nat-traversal doc (Nostr-signaled port advertisement plus UDP NAT-traversal protocol, FIPS as an example implementation, suitable for eventual NIP submission). - Top-level docs/getting-started.md walking through the binary-installer-only Install story. - packaging/common/hosts pre-populated with the eight public test-mesh nodes so shortnames resolve out of the box on every fresh install. ## Changes - 23 wire-format diagrams relocated to reference/diagrams/ alongside the wire-formats move. - 4 design diagrams corrected against source code (fips-protocol-stack, fips-identity-derivation, fips-coordinate-discovery, fips-routing-decision). - 10 pre-existing design docs reconciled with current source. Numeric corrections: stale link-MMP report bounds (now [1s, 5s] with 200 ms cold-start floor); UDP default MTU (now 1280, IPv6 minimum); node_addr formula (SHA-256(pubkey)[..16]); Noise patterns (IK at link, XK at session); peer-ACL semantics (strict allowlist requires ALL in peers.deny); daemon DNS upstream ([::1]:5354); on-the-wire bloom-filter size (1,071 bytes); obsolete Cargo-feature references (PR #79 dropped them) removed. - Transport framing tightened across the docs: TCP is for UDP-filtered networks (not NAT traversal); Tor is a deployment mode (not failover); WebSocket dropped (not a shipped FIPS transport); WiFi promoted to Implemented via Ethernet in infrastructure mode; classic-Bluetooth row removed (BLE is the only Bluetooth-mode transport). - docs/design/fips-gateway.md rewritten end-to-end to lead with the niche-feature framing and the two-halves structure. Title moved from "FIPS Outbound LAN Gateway" to "FIPS Gateway"; architecture section describes the common machinery (the fips-gateway service, the nftables table, the control socket) before splitting into separate "Outbound Half" and "Inbound Half" sections of equal weight; security considerations split per-half; no Future Work section (speculative directions live in the project tracker, not in protocol design docs). Inbound port forwarding is a first-class half rather than a buried "Implemented Extensions" subsection. - Gateway terminology unified across all gateway docs as a separate Linux service running alongside the fips daemon (its own systemd unit / OpenWrt init script). Container- pattern terms (sidecar) are reserved for the Docker/Kubernetes sidecar deployment examples — the testing/sidecar/ tree, examples/k8s-sidecar/, examples/sidecar-nostr-relay/, examples/wireguard-sidecar-macos/, and the related CHANGELOG / top-level README entries — where the term carries its standard container meaning. - Net-new design body content: rekey section in fips-mesh-layer (Noise IK msg1/msg2 over the established link, K-bit cutover, drain window, smaller-NodeAddr-wins tie-breaker on dual-init); Mesh Size Estimation and Antipoison FPR Cap sections in fips-bloom-filters; Mesh-Interface Query Filter subsection in fips-ipv6-adapter; failure-suppression knobs and clock- skew tolerance in fips-nostr-discovery; loop-rejection and mid-chain ancestor swap added to spanning-tree propagation / stability rules; Priority Chain in fips-mesh-operation renumbered to match the routing-decision diagram. - Top-level README: dropped the stale nostr-discovery cargo-feature parenthetical. docs/README.md and the four section READMEs (tutorials, how-to, reference, design) refreshed for the new structure; index rows reflect both halves of the gateway feature and the new fips-gateway CLI reference. - Cargo.toml [package.metadata.deb] assets path updated for the fips-security.md move; .gitignore /reference/ rule anchored to repo root so docs/reference/ is trackable. - packaging/openwrt-ipk/files/etc/fips/fips.yaml configuration-doc URL updated to the new docs/reference/configuration.md location. ## Deletions - docs/design/fips-intro.md (split into the three new intro design docs). - docs/design/document-relationships.svg (orphan, no longer referenced). - docs/proposals/ tree removed; the only proposal it contained (the Nostr UDP hole-punch protocol) was rewritten as the new generic design/port-advertisement-and-nat-traversal.md.
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 pkg # macOS .pkg installer
make zip # Windows .zip package
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
macos/ macOS .pkg installer via pkgbuild
systemd/ Generic Linux systemd tarball packaging
openwrt/ OpenWrt .ipk packaging via cargo-zigbuild
windows/ Windows .zip package with service scripts
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.
macOS (.pkg)
Built with pkgbuild (included with Xcode command-line tools). Installs
binaries to /usr/local/bin/, config to /usr/local/etc/fips/, sets up
the /etc/resolver/fips DNS resolver for .fips domains, and loads a
launchd daemon. The TUN device is named utun<N> (kernel-assigned)
rather than fips0.
# Build
make pkg
# Install
sudo installer -pkg deploy/fips-<version>-macos-<arch>.pkg -target /
# Remove
sudo packaging/macos/uninstall.sh
Windows (.zip)
A ZIP archive containing binaries, default config, and PowerShell service helper scripts. Requires the wintun driver for TUN support.
# Build
make zip
# Or directly
powershell -File packaging/windows/build-zip.ps1
# Extract and install as service (requires Administrator)
Expand-Archive deploy\fips-<version>-windows-x86_64.zip -DestinationPath fips
cd fips
powershell -File install-service.ps1
# Uninstall (preserves config)
powershell -File uninstall-service.ps1
# Uninstall and remove config
powershell -File uninstall-service.ps1 -RemoveAll
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.
