Johnathan Corgan 37196604d7 Prepare the v0.5.3 release notes, changelog and documentation corrections
Move the staged changelog entries under a 0.5.3 heading dated
2026-10-16, marked provisional in the heading itself, and leave an empty
Unreleased section above it. The topic groups follow the order the 0.5.2
section uses, and fixes that described one mechanism in several entries
now read as one: the gateway's virtual IP handling, the macOS sending
threads, the transport counters, the forged and unreadable SessionMsg3
and SessionSetup cases, and the same-epoch msg1 handling. No entry's
detail was dropped.

Add the release notes and mirror them byte for byte to RELEASE-NOTES.md,
with every link absolute and each paragraph on one line. They lead with
who should upgrade and what to do first: the SSH rule and gateway
forwarding before an OpenWrt upgrade, the farthest-first order for
routers reached over an 802.11s mesh, the Windows installer's stop on a
key left in \etc\fips, the refusal of a config that configures nothing,
the gateway's LAN-only translation and pool checks, and the changed
fips.nft, including what the systemd tarball does with an edited copy.
The upgrade steps say to restart fips after the network reload on an
OpenWrt mesh or gateway router, since a running daemon does not form
links over a recreated interface, and give the upgrade, reload and
restart as one detached command for a router reached over SSH. The
FreeBSD restart after the package upgrade is required, because pkg ends
the daemon the package starts. On Windows, a key moved out of \etc\fips
needs node.identity.persistent: true beside it and the old fips.yaml
deleted, and a service registered by hand is checked with sc.exe qc
first. On Debian, the steps cover each answer at the fips.nft prompt, an
upgrade run without a terminal, and masking fips-dns on a host that
renamed the TUN, which fips-dns does not support. A gateway on a VLAN
device on a bridge is affected only when br_netfilter passes bridged
IPv6 to the firewall, and only for clients whose traffic enters the
bridge untagged; the notes say how to check and what the workaround
costs, and that hosts off gateway.lan_interface lose .fips access.
They state the wire-format comparison and what it does not cover, the
limits that remain, the advisories accepted with the release including
RUSTSEC-2024-0449, that no crate was added to the lockfile, the
fips-mesh crate name and how a dependent names it, what was measured
and what was not, and the contributors.

The README's status badge, release-notes link and status paragraphs
follow the release, without naming a branch.

Correct documentation that no longer matches the release:

- The fips and configuration references say the Windows \etc\fips
  config probe is deprecated, that the daemon warns when it loads a
  config from there, and that from v0.6.0 the search no longer looks
  there.
- Getting started no longer says there is no cargo install path, since
  the crate is published; it says cargo install fips-mesh installs only
  the binaries and is not how to install the daemon.
- The reachability how-to names its probe placeholder as a substitution,
  and the gateway port-forward recipe marks its example mesh address as
  the one to replace.
- The mesh firewall how-to says the systemd tarball keeps an edited
  fips.nft and writes the new one as fips.nft.template.
- The gateway design document and the configuration reference state the
  bridge netfilter condition under which a VLAN device on a bridge does
  not serve its clients.
- The FreeBSD package README no longer says the package restarts the
  services on upgrade, and says to restart them by hand.
- The OpenWrt package README's mesh upgrade order adds the fips restart
  after the reload, as a detached command.

FIPS FreeBSD packaging

Builds a native FreeBSD .pkg shipping fips, fipsctl, fipstop, rc.d services, and .fips DNS integration. fips-gateway is excluded (its NAT backend is nftables, Linux-only).

Platform notes: the Ethernet and BLE transports are not available on FreeBSD (UDP, TCP, Tor, and Nym are). The UDP datapath deliberately uses the portable single-packet receive loop — FreeBSD's recvmmsg(2) is a libc loop over recvmsg, not a kernel batch, so the Linux/macOS batched arm would gain nothing — and the connected-UDP fast path is not compiled pending FreeBSD-specific SO_REUSEPORT validation.

Build

./packaging/freebsd/build-pkg.sh            # cargo build --release + pkg create
./packaging/freebsd/build-pkg.sh --no-build # package existing release binaries

Output: deploy/fips-<version>-freebsd-<arch>.pkg. pkg versions cannot contain - or +, so both are mapped to .: a Cargo version of <x.y.z>-dev becomes fips-<x.y.z>.dev-freebsd-amd64.pkg.

Install

pkg add ./deploy/fips-<version>-freebsd-<arch>.pkg
# post-install seeds this from the sample if absent, at mode 0600
vi /usr/local/etc/fips/fips.yaml
sysrc fips_enable=YES fips_dns_enable=YES
service fips start
service fips_dns start
fipsctl show status

Config installs sample-style (@sample semantics via manifest scripts), so an edited fips.yaml survives upgrade/removal. fips.yaml is installed 0600 — it may hold the node's private key (nsec:). The daemon runs under daemon(8) with pidfile /var/run/fips/fips.pid and logs to /var/log/fips.log (rc.conf knobs: fips_config, fips_flags, fips_logfile).

The log is rotated by /usr/local/etc/newsyslog.conf.d/fips.conf: five bzip2-compressed generations of 1000 KB. daemon(8) runs with -H and records its own pid in /var/run/fips/daemon.pid; newsyslog signals that pid after the rename, and daemon(8) reopens the log. The entry covers the default fips_logfile only, so a log moved elsewhere needs its own newsyslog entry. The entry belongs to the package and is replaced on upgrade.

The package creates a fips group; members can run fipsctl and fipstop without root (pw groupmod fips -m <user>, then re-login). On pkg upgrade the services are stopped before the binaries are replaced, and the package starts them again afterwards if enabled, but pkg 2.8.4 ends a daemon that a package script starts once pkg exits (measured with pkg install of a package file), so that start does not last. After an upgrade, run service fips restart and, if you use it, service fips_dns restart. On pkg delete the services are stopped and the .fips resolver drop-in is removed.

.fips DNS integration

The daemon answers .fips queries on [::1]:5354. fips_dns points the system resolver's fips. zone there; backends tried in order: base local_unbound (drop-in /var/unbound/conf.d/fips.conf), pkg unbound, pkg dnsmasq. The unbound drop-in must (and does) set:

  • do-not-query-localhost: no — unbound's default silently refuses loopback forwarders, SERVFAILing every .fips query.
  • do-ip6: yes — the daemon binds ::1 only.
  • domain-insecure: "fips." — the zone is unsigned.

One-time host resolver setup (NOT automated)

The package configures the fips. zone only; making the local resolver the system resolver is an operator decision. On a typical box:

sysrc local_unbound_enable=YES
local-unbound-setup 1.1.1.1 9.9.9.9   # explicit upstreams — see below
service local_unbound restart

Field-tested caveats (fips-dns-setup detects and warns about each):

  • /etc/resolv.conf must list a loopback nameserver (ideally only 127.0.0.1), or nothing ever queries unbound and .fips cannot resolve.
  • Do not use a home-router DNS proxy as unbound's upstream. Many CPE forwarders are EDNS-broken; unbound always sends EDNS, so every public query SERVFAILs. Forward to real resolvers (ISP or public).
  • Remove options edns0 from /etc/resolv.conf if present, and set resolv_conf_options="" in /etc/resolvconf.conf so resolvconf(8) does not re-add it — against an EDNS-broken router it breaks libc resolution outright.
  • Never run local-unbound-setup with no arguments while resolv.conf already points at 127.0.0.1 — it snapshots that as upstream and forwards unbound to itself.

Debugging

drill -p 5354 <npub>.fips @::1 AAAA   # daemon directly (bypasses unbound)
drill <npub>.fips AAAA                # full chain; SERVER: must be 127.0.0.1
cat /var/run/fips/dns-backend         # which backend fips_dns configured

The TUN interface gets a kernel-assigned name (tun0, tun1, ...), like utun on macOS, and is destroyed automatically when the daemon exits. ifconfig <name> prints Opened by PID <n> for the process holding a tun device.
