Carve the nostr rendezvous engine's decision logic out of the async
NostrRendezvous driver into synchronous, clock-injected cores, following
the failure_state.rs pattern: sync state behind std::sync::Mutex, time
passed in as now_ms, no .await and no I/O in the core. The driver performs
all relay/socket I/O and executes the returned plans.
- AdvertMachine (src/nostr/advert.rs): advert publish/cache/fetch/prune
decision logic; the driver executes a returned PublishPlan.
- TraversalMachine (src/nostr/traversal_machine.rs): the engine-scoped
cross-session decision state -- in-flight-initiator dedup, the dual-init
responder suppression election, and the replay/seen-session cache.
- classify_punch_packet (src/nostr/traversal.rs): a pure classifier for
the punch recv loop's packet branch table.
The driver keeps all I/O, the NAT punch send cadence, the offer-slot
admission semaphore, and the pending-answer oneshot routing. Behavior-
neutral: no wire, config-key, or metric change. Adds unit coverage for
the advert plans, election ordering, replay eviction, initiator dedup,
and punch classification.
Moving the nostr rendezvous engine to src/nostr/ (and mDNS to src/mdns/)
changed the module-path-derived tracing targets from
fips::discovery::nostr::* to fips::nostr::*. Update the RUST_LOG filters
in the NAT and mesh-lab test compose files and the resolve-peers-via-nostr
tutorial's debug recipe to the new targets so trace configs and the
documented journal-watch command keep emitting the intended lines.
Without this, the stun-faults suite's Phase-0 pre-flight (which greps the
daemon journal for the debug-level "STUN observation succeeded" /
"traversal: initiator STUN observed" lines) saw those lines suppressed —
the daemon behaved correctly, but the stale RUST_LOG target hid the
evidence. Test-harness and docs only; no source or behavior change.
Pull the rendezvous driver state and the movable driver logic out of the
Node struct into the src/nostr home. A new RendezvousDriver owns the
engine handle and the four bookkeeping fields (traversal start time,
startup-sweep latch, adopted bootstrap-transport set and their npubs)
that previously sat loose on Node; Node holds a single driver field and
reaches the same data through thin accessors, including the rx-loop
hot-path protocol-mismatch hook.
The advert build/refresh, the via_nostr fallback-address resolve, the
overlay-endpoint-to-PeerAddress mapping, and the bootstrap request move
onto the driver, taking their Node inputs explicitly (a transport-
endpoint snapshot for advert building) rather than reading Node fields
directly. Transport/connection-table-bound work (traversal adoption,
bootstrap-transport cleanup, the open-discovery sweep, and the outbound
budget calculators) stays on Node as thin glue that calls into the
driver.
Behavior-neutral relocation: statements moved verbatim, no logic, wire,
config-key, or metric changes. lifecycle.rs shrinks ~230 lines. cargo
fmt/build/clippy clean; lib suite 1547 passing (baseline unchanged).
Relocate the overlay peer-rendezvous subsystem out of the overloaded
src/discovery/ tree into two focused, independent homes: src/nostr/
(relay-mediated overlay endpoint advertise/resolve/auto-mesh plus NAT
traversal) and src/mdns/ (link-local DNS-SD rendezvous). The two
subsystems are independent, so they get separate homes rather than
sharing one.
Drop the ambiguous "Discovery" stem from their identifiers in favor of
"Rendezvous": NostrDiscovery -> NostrRendezvous, LanDiscovery ->
LanRendezvous, and the matching config, policy, field, and method names.
The former src/discovery.rs handoff types (EstablishedTraversal,
BootstrapHandoffResult, the punch-packet helpers) fold into
src/nostr/handoff and stay reachable via the crate-root re-exports.
Pure relocation and rename: no logic, wire-format, config-key, metric,
or tracing-target changes. The operator-facing node.rendezvous.nostr.*
and node.rendezvous.lan.* config keys and the fips-overlay-v1 advert
namespace are byte-identical. cargo fmt/build/clippy clean; lib test
suite 1547 passing (baseline unchanged).
The identifier "discovery" named three unrelated subsystems; the FMP
overlay coordinate-lookup subsystem is now consistently "lookup". This
finishes the concept-#1 rename across the shell, config, and metric
layers left after the earlier proto-layer rename:
- Handler module node::handlers::discovery -> node::handlers::lookup, and
reset_discovery_backoff -> reset_lookup_backoff.
- The Node lookup-engine field Node.discovery -> Node.lookup, renamed by
resolved binding so the metrics().discovery and node.discovery config
paths are left untouched.
- The lookup metric types DiscoveryMetrics -> LookupMetrics,
DiscoveryStatsSnapshot -> LookupStatsSnapshot, and Metrics.discovery ->
Metrics.lookup.
Two surfaces cross a stability boundary and ship behind a compatibility
window, both marked in-code for removal at the v2 cutover:
- The control-socket metric family is dual-emitted under both "discovery"
(deprecated alias) and "lookup" so existing dashboards keep working.
- The node.discovery.* config table is split into node.lookup.* (mesh
lookup scalars) and node.rendezvous.* (nostr/lan peer rendezvous).
NodeConfig does not deny unknown fields, so a naive rename would make a
deployed node.discovery: block deserialize into nothing and silently
revert every setting to default. A deprecated all-Option
DiscoveryConfigCompat field captures a legacy block and a new post-parse
Config::normalize_deprecated_keys pass folds it into the new tables with
a one-time deprecation warning.
Flip the packaged fips.yaml templates to the new keys, add legacy/new/
scalar compat parse tests, and record the split and deprecations in the
CHANGELOG. Behavior-neutral; fmt/clippy clean, lib suite green.
The previous portability fix bounded the powi test's drift from std::powi
at an absolute ULP count, but Windows/MSVC drift grows with the exponent
(3 ULP by exp=14), so no fixed ULP bound is portable.
Replace the ULP oracle with a loose relative-tolerance sanity sweep
(1e-11), which any sane libm clears by ~1000x regardless of exponent
while still catching a grossly wrong impl. Add a golden-bit pin for the
exp=14 case that exposed the growth. The powi function is unchanged; the
golden-bit determinism pins already passed on Windows.
The powi guard test asserted our square-and-multiply result was
bit-for-bit equal to f64::powi, which failed the Windows unit-test job by
one ULP. f64::powi is not portably bit-stable: Linux and macOS lower it
to compiler-rt's __powidf2, but Windows/MSVC rounds differently.
Our square-and-multiply is pure IEEE-754 f64 multiplication and is
therefore deterministic across every platform, which is the property that
actually matters for mesh nodes to agree on bloom FPR and backoff timing
regardless of OS. Replace the std bit-equality assertion with golden-bit
pins on our own output (locking that cross-platform determinism) plus a
bounded-drift sanity sweep against std::powi. The powi function itself is
unchanged.
Rename src/proto/discovery to src/proto/lookup and bring the module's naming
onto the lookup stem, matching its concept: a mesh lookup of a node's
coordinates from its pubkey, sent into the mesh as a bloom-filter-guided
multicast request that returns a unicast response with the coordinates.
- the module directory and its declaration (proto::discovery -> proto::lookup)
- exported types: DiscoveryAction -> LookupAction, DiscoveryBackoff ->
LookupBackoff, DiscoveryForwardRateLimiter -> LookupForwardRateLimiter,
MAX_RECENT_DISCOVERY_REQUESTS -> MAX_RECENT_LOOKUP_REQUESTS, and the Discovery
state struct -> Lookup
- internal terminology: doc comments, the "overlay-lookup" phrasing, the
empty_discovery/suppressing_discovery test helpers, and the disc
parameter/variable all take the lookup names
- the already-lookup-named wire types (LookupRequest/LookupResponse) are unchanged
Behavior-neutral: no wire bytes or decision logic change. Two references are
intentionally kept as "discovery": the still-named node::handlers::discovery
shell module and the node.discovery.* config keys, which belong to the broader
disambiguation of the shell, config, and metric surfaces still to come.
Bring the proto tree closer to a std+alloc-only posture, behavior unchanged on
every decision path:
- Sweep the remaining std::fmt and std::collections imports over to core::fmt
and alloc::collections across the wire codecs and their tests. Subsystem files
that shadow the core name with a child core module use the leading-colon
::core::fmt form. Imports only.
- Replace the two f64::powi calls (bloom false-positive-rate, FMP backoff timer)
with a shared core-only square-and-multiply helper in proto/math, bit-identical
to std::powi (a guard test pins this against every exponent the codecs reach),
and route the diagnostic estimated-count natural log through libm::log. The FPR
reject decision and the backoff timer are bit-for-bit unchanged; only the
debug-only count estimate may differ by at most one ULP.
Introduce a shared proto/codec module with a cursor Reader (short reads fail with
MessageTooShort { expected: position + needed, got: total }) and an append Writer,
and adopt them across the seven subsystem wire codecs, replacing the repetitive
manual slicing, try_into, and from_le_bytes extraction. Each existing length check
maps to the reader (an up-front minimum becomes require at position zero, so the
per-field expected values, including the tree-announce expected 99, are reproduced
exactly); the bloom exact-length check stays explicit since it also rejects
over-long payloads. Encoded bytes and decode decisions are unchanged.
Replace Malformed(String) with a no_std-clean set: Malformed(&static str)
for the static decode diagnostics, BadSizeClass { got, max } for the two
bloom size-class checks, and typed sources BadCoord(CoordError) /
BadBloom(BloomError) for the coordinate and bloom construction failures. Add a
dedicated CoordError so proto/coord no longer depends upward on stp TreeError,
resolving the temporary inversion from the coordinate relocation. Drop the
thiserror derive from the four proto error types (Error, TreeError, BloomError,
CoordError) in favor of hand-rolled core::fmt::Display and core::error::Error
impls. thiserror remains in use elsewhere in the crate. Wire decode decisions
are unchanged; only the error type and its diagnostic text change.
Hoist the two line-for-line-identical per-destination minimum-interval limiters
(discovery forward, routing error) into a shared PerAddrRateLimiter, and fold
the duplicated exponential-backoff math (discovery originator, FMP retry) into a
shared backoff_ms helper, both in a new proto/rate_limit module. The subsystem
limiters become thin delegating newtypes so should_forward/should_send and the
backoff call conventions are preserved. Behavior is byte-identical.
Two behavior-neutral relocations, wire bytes unchanged:
- Move the ParentDeclaration type and its impls out of state.rs into a dedicated
declaration.rs, re-exported at the same path, and relocate the inline wire.rs
test module into tests/wire.rs alongside the other stp unit tests (reusing the
shared test helpers). wire.rs drops to non-test code only.
- Move TreeCoordinate, CoordEntry, and the coordinate wire codec out of
proto/stp into a shared proto/coord module (a peer of proto/link), re-exported
from proto::stp so every existing import path keeps resolving unchanged.
Coordinate is a shared addressing primitive with many non-stp consumers, so it
no longer belongs under the spanning-tree subsystem. The codec carries a
documented temporary dependency on stp::TreeError until a dedicated CoordError
is introduced.
evaluate_parent no longer reads the injected clock: it returns a ParentEval of
Mandatory, Discretionary, or None, and the flap/hold-down veto is applied at the
edge via a new TreeState::is_switch_suppressed(now_ms), gating only the
discretionary arm. classify_announce/classify_periodic take the pre-computed
switch_suppressed bool instead of now_ms, so the whole classify ladder is
clock-free; the shell callers (tree announce/periodic re-eval, MMP first-RTT
re-eval, handle_parent_lost) compute the veto verdict. The no-coords parent
case stays discretionary (veto-gated) exactly as before. Behavior unchanged;
the veto tests now assert the moved responsibility.
Reorganize the MMP subsystem, behavior unchanged throughout:
- Restore the pre-migration role split: move SenderState into sender.rs,
ReceiverState (with its GapTracker helper) into receiver.rs, MmpMetrics and
RrLog into metrics.rs, and PathMtuState into path_mtu.rs, leaving the Mmp
aggregate plus the peer/session state in state.rs (1339 to 196 lines). Home
the module constants in a new limits.rs and re-export them at the same paths.
Pure code-motion with module rewiring; visibility unchanged.
- Dissolve the 97-line src/mmp shell, which held only MmpConfig and the
monotonic mono_ms() clock: move MmpConfig into config/node.rs (re-exported as
crate::config::MmpConfig), move mono_ms() into a new top-level src/time.rs
shell time seam, repoint all callers, and delete src/mmp/. Also correct stale
src/mmp/ doc-comment path labels to proto/mmp/ where they name the protocol
primitives.
Two behavior-neutral discovery cleanups:
- Move MAX_RECENT_DISCOVERY_REQUESTS out of the node discovery handler into the
discovery subsystem limits module and re-export it, keeping the two use sites
unchanged. Same value and semantics; only its home moves.
- Remove the ambient rand draw from LookupRequest by deleting generate() and
having the shell draw the random request_id and pass it into the existing
new() constructor. Same per-request u64 draw, now at the shell, leaving the
discovery codec free of ambient RNG reads.
The false-positive-rate primitive (fill ratio raised to the hash count) was
inlined at three sites. Hoist it into a BloomFilter::fpr() method and call it
from all three; the threshold/policy logic stays at the call sites. Behavior
and result bytes are unchanged.
Migrate the FSP end-to-end session subsystem into src/proto/fsp/ following the
established sans-IO shape, and retire the src/protocol grab-bag now that FSP was
its last occupant.
Relocate the FSP session wire (node/session_wire.rs plus the FSP message types
from protocol/session.rs) into proto/fsp/wire.rs. Hoist the pure decision logic
into proto/fsp/core.rs over plain-data SessionSnapshots returning an ordered
FspAction list the shell drives: session-rekey policy, msg3-resend
classification, post-decrypt epoch reaction, setup/dual-init tie-break,
coords/path-MTU emit-policy, bounded pending-queue, and IPv6 ECN. The
crypto-owning SessionEntry stays shell-side in node/session.rs (matching the FMP
ActivePeer pattern); proto/fsp is wire + core + limits only, with no proto->noise
dependency and no crypto.
Move the coords helpers to proto/stp/ (they serialize TreeCoordinate), and split
SessionMessageType: the encrypted-inner 0x10-0x1F variants stay in proto/fsp/wire.rs
while the 0x20-0x2F routing signals become a new RoutingSignalType in
proto/routing/wire.rs. Migrate the session-MMP shell adapter, which continues to
drive proto/mmp/.
Retire src/protocol: LinkMessageType and SessionDatagram move to a new shared
proto/link.rs, ProtocolError becomes proto::Error (relocated verbatim), the
deprecated MessageType alias and the unimported PROTOCOL_VERSION are dropped, and
src/protocol/ is deleted along with its lib.rs module declaration.
Behavior-neutral: wire bytes unchanged, oracle tests pass unedited except
mod-path relocation; adds rekey/epoch characterization tests and pure
poll/emit-policy core tests.
Migrate the v1 bloom filter subsystem into src/proto/bloom/, matching the
discovery/routing/fmp/mmp/stp reference layout and completing the proto/
relocation series for the data/wire subsystems.
- wire.rs: the FilterAnnounce (0x20) codec, moved from protocol/filter.rs
- core.rs: the pure BloomFilter algorithm (hash/insert/contains/merge/
as_bytes/from_bytes/estimated_count), moved from bloom/filter.rs
- state.rs: BloomState (per-peer inbound store, compute_outgoing_filter,
the injected-clock send debounce), moved from bloom/state.rs
- limits.rs: the v1 sizing constants
- mod.rs: module wiring + the BloomError enum
- tests/: the unit suite split by target (core/state/wire), no inline tests
no_std+alloc hygiene: core::fmt over std::fmt, the tracing dependency
dropped from the pure filter, and std collections replaced with
BTreeMap/BTreeSet (NodeAddr: Ord) for deterministic iteration. The pure
filter combination stays a BloomState method; the two irreducible shell
gathers (peer_inbound_filters, build_filter_announce) remain in the async
shell. Wire bytes and observable behavior are unchanged; full local CI
green (36/36) including the bloom-storm chaos gate.
Migrate the full non-async spanning-tree surface into proto/stp/, mirroring the
discovery/routing/fmp/mmp conversions. The classification ladder (parent-switch /
self-root / loop-drop / ancestry-update / periodic-rebroadcast / parent-lost) moves
out of the async node handlers into a pure Stp classify layer returning a
TreeDecision the shell drives, with effect ordering and per-arm invalidation
preserved verbatim. src/tree/ relocates wholesale: TreeState + ParentDeclaration data
+ coordinates into proto/stp/{state,coordinate}, the flap-dampening / hold-down
cluster into a FlapDampener in limits.rs, and the wire codec into wire.rs. The clock
is injected as u64 (wall-clock secs for the escaping declaration timestamp, monotonic
ms for the dampening timers via mmp::mono_ms); declaration crypto is field-partitioned
so sign/verify/hash run in the shell while the in-core modules carry data +
signing_bytes only. Peer maps/sets move to BTree; core/state/coordinate/limits are
core+alloc clean, with wire.rs the one std-tethered file. Behavior-neutral:
characterization tests added for the handler decision arms; convergence suite and
ci-local (36/36) green.
Migrate the FMP discovery decision logic out of the async handlers into
synchronous, runtime-agnostic sans-IO state machines owned by the protocol
structs, with I/O pushed to the edges. Pulls the full decision surface into a
pure core (backoff, rate-limit, planners, response routing), consolidates the
tests into a per-module tree with a shared crate testutil, and injects a u64
wall-clock so the core is free of Instant and std time.
Also brings the module toward no_std+alloc: the four discovery maps use
alloc::collections::BTreeMap (HashMap's RandomState is std-only), Arc is spelled
alloc::sync::Arc, the backoff-reset log lives in the shell (the core returns the
cleared count so observability stays out of the pure core), and the crate root
names alloc directly. The one remaining tether is ProtocolError's
std::error::Error coupling in the wire codec.
First subsystem of the broader sans-IO refactor; establishes the extraction
patterns and conventions carried forward to the remaining protocols.
handle_peer_removal_tree_cleanup reparents or self-roots the node when
its parent link drops, but omitted the coordinate-cache invalidation that
every other position-change path performs. Cached entries for downstream
destinations kept the node's now-stale coordinate prefix, and because
find_next_hop refreshes the TTL on every routing access, an actively
routed stale entry never self-expired — corrected only by a fresh insert.
Mirror the loop-detection branch: inside the parent-loss changed block,
invalidate both classes — invalidate_via_node (reparent) and
invalidate_other_roots (self-root). Add regression tests for a parent-link
removal that reparents (via-node entry dropped, same-root sibling
preserved) and one that self-roots (both via-node and stale old-root
entries dropped).
Add a "Running CI locally" section to testing/README.md covering the
ci-local.sh orchestrator: the per-run FIPS_CI_RUN_ID override and how it
scopes compose projects, image tags, and per-chaos-child subnets so
simultaneous runs on one host never collide; the cancellation exit codes
(130/143 vs 0/1) and how a preempting worker interprets them; and the
label-based cleanup via --reap / ci-cleanup.sh.
A CI worker may preempt an in-flight ci-local.sh run (SIGTERM, then SIGKILL
after a grace period) to restart on a newer commit. For that kill to be safe,
the script must clean up after itself and never let a dying run collide with
its restart. It previously had no signal handling, shared the default compose
project name across runs, and tore down each suite only at the suite end.
- Derive a per-run id (honoring FIPS_CI_RUN_ID, else short-sha+random) and
namespace every docker resource to it: a fipsci_<run>_<suite> compose project
per suite and per parallel chaos child, and per-run image tags
(fips-test:<run>, fips-test-app:<run>) retagged to :latest only after both
builds succeed so :latest never points at a half-built image.
- Install a bounded, idempotent teardown trap on SIGTERM/SIGINT (+ EXIT): reap
parallel chaos children, then force-remove this run's docker resources via
the new ci-cleanup.sh, wrapped in timeout so a stuck down cannot wedge it.
- Exit 143 (SIGTERM) / 130 (SIGINT), distinct from 0 (pass) / 1 (failed), so a
preempting worker tells a cancelled run from a real failure.
- Add ci-cleanup.sh (also ci-local.sh --reap): force-removes leftover CI
resources by the com.corganlabs.fips-ci=1 label and the fipsci_ project
prefix, robust to however a prior run died.
- Label every per-suite docker resource so the label sweep reaps it after a
SIGKILL regardless of network name: direct docker run/network resources, the
sidecar compose services, and every per-suite compose network (acl-allowlist,
boringtun, firewall, nat, static, both tor suites, and the chaos generator
template). Parametrize the static/sidecar compose image refs so the per-run
tags are honored.
- Give each parallel chaos child a unique /24 from 10.30.x (a new --subnet
override on the sim CLI, assigned per-child in ci-local.sh) so parallel
children never collide on a shared docker subnet, and a chaos net can never
span a fixed-subnet suite (sidecar/static in 172.20.x). 10.30.x sits outside
docker's default-address-pool range, so an auto-assigned net cannot land on
it either; node IPs derive from the subnet, so no scenario config changes.
Replace the fixed post-first-rekey and post-second-rekey settle sleeps in
the rekey integration test, and the fixed-deadline baseline wait in the
interop test, with the deterministic wait_until_connected progress-aware
polling helper already used for the initial baseline convergence.
Each converted site fails fast with structured diagnostics when the mesh
is stuck and extends its deadline only while pairwise reachability is
still climbing, removing the wall-clock settle windows that produced
intermittent connectivity failures after a rekey.
maint carries only its 0.4.1-dev version bump; master keeps its own
0.5.0-dev development version. Recorded as a linkage merge so later
forward-merges of real fixes land cleanly.
The shared fips.yaml ships ethernet.wan.interface: "eth0", the default
WAN port on OpenWrt 24 and earlier. OpenWrt 25 (DSA) boards, which the
.apk package targets, name the WAN port "wan" instead. Rewrite the
staged copy at build time so the as-installed config binds the Ethernet
transport to the right port out of the box, without maintaining a second
copy of the config file. The .ipk package keeps "eth0".
Update the openwrt README to document eth0 (24) vs wan (25/DSA) and add
a CHANGELOG entry.
A transient timeout uploading the built .ipk to the Blossom CDN
(blossom.primal.net) failed the entire OpenWrt Package run, and because
the GitHub release job depends on the build jobs, a CDN blip would block
every OpenWrt artifact from the release. Blossom/nostr distribution is
supplementary; the package already ships as a GitHub release artifact.
Wrap the upload in a 3-attempt retry with backoff to absorb transient
timeouts, mark the step continue-on-error so a persistent outage no
longer fails the build, and guard the NIP-94 publish on the upload
succeeding so no event is created with an empty URL. Applied to both the
.ipk and .apk build jobs.
Claude-Session: https://claude.ai/code/session_01A2pYfSypNmmG4HyHwZuLex
Prepare the source tree for the v0.4.0 release cut, leaving the version
at 0.4.0-dev (the version bump rides a separate release-candidate
commit).
- CHANGELOG: backfill the missing entry for the route-class transit
counters and fipstop routing-tab reorg, then reorganize the Unreleased
block from a flat per-commit list into topic-grouped subsections
mirroring the 0.3.0 entry (coalescing interim fixes into net-effect
descriptions without dropping technical detail), and stamp it as
[0.4.0] - 2026-06-21 with a fresh empty Unreleased block. The date is
provisional and reconfirmed at the final tag.
- Release notes: refresh both RELEASE-NOTES.md and the versioned archive
(kept byte-identical) to cover the OpenWrt .apk packaging, the Nix
flake, the macOS self-traffic checksum fix (#117), and the route-class
transit counters.
- README: bump the status badge to v0.4.0 so it matches the prose.
Claude-Session: https://claude.ai/code/session_01A2pYfSypNmmG4HyHwZuLex
Add six forwarding counters that partition transit-forwarded packets by their
tree relationship to the chosen next hop: tree-up (peer is our ancestor),
tree-down (peer is our descendant and the destination is within its subtree),
tree-down-cross (peer is our descendant but the destination is outside its
subtree), cross-link descend (lateral peer, destination within its subtree),
cross-link ascend (lateral peer, destination outside its subtree), and
direct-peer. The six classes sum to forwarded_packets, asserted by a unit
test. Classification is computed from tree coordinates at the transit
chokepoint, so the error-signal routing callers are excluded.
The two "outside the chosen peer's subtree" classes are both up-and-over
forwards but differ in what they depend on. Tree-down-cross is the
dive-to-tree-child cut-through: we forward down to our own child for a
destination not beneath it, which is only possible because the child
advertised cross-link reach upward to us, beyond its own subtree. Its count
measures how much forwarding depends on that upward advertisement, i.e. what
would change if cross-link advertisements were narrowed to subtree-entry only.
Cross-link ascend, by contrast, uses the node's own lateral cross-link learned
from a peer's split-horizon advertisement, so it does not depend on any upward
advertisement.
Surface the counters through the forwarding stats snapshot (control socket,
show_routing and show_status) and reorganize the fipstop routing tab so its
two columns separate own/endpoint traffic (received, delivered, originated)
from forwarded/transit traffic (the route-class breakdown and drop reasons),
with the tree-down-cross line visually flagged.
Add OpenWrt .apk packaging for OpenWrt 25+, where apk-tools is the
mandatory package manager. The existing .ipk continues to cover OpenWrt
24.x and earlier. Built SDK-free like the .ipk: it reuses the
cargo-zigbuild cross-compile and the shared installed-filesystem payload
under openwrt-ipk/files, and assembles the ADB container with the
official `apk mkpkg` applet from apk-tools 3.0.5 built from source, so no
OpenWrt SDK image is needed.
The package-openwrt workflow is refactored so a single compile-binaries
job cross-compiles and strips each arch once; both the .ipk and .apk
packagers consume the binaries via a new --bin-dir flag instead of each
recompiling. A build-apk job (aarch64, x86_64) builds apk-tools,
packages, and structurally verifies the .apk with `apk adbdump`. Releases
now publish .apk artifacts and checksums alongside .ipk; the release
download is scoped to fips_* so the shared raw-binary artifacts are not
swept into the published release. apk-version.sh maps a release tag or
commit height to an apk-tools-valid version, covered by a case-table test.
Packages are unsigned, installed with `apk add --allow-untrusted`,
matching the .ipk posture.
Also fix the OpenWrt control socket: the init script now pre-creates
/run/fips before starting the daemon, the procd equivalent of the systemd
unit's RuntimeDirectory=fips. Without it, on a fresh boot the daemon
resolves its control socket to /tmp (since /run/fips does not yet exist),
while fips-gateway later creates /run/fips for its own gateway.sock,
leaving fipsctl/fipstop resolving a /run/fips/control.sock the daemon
never bound.
Self-addressed TCP/UDP connections to a node's own <npub>.fips address
half-opened and hung on macOS. macOS routes self-traffic as loopback (a
LOCAL route via lo0), which defers the transport TX checksum, but the
point-to-point utun then egresses the packet into the daemon with only
the pseudo-header partial checksum present. The hairpin path added in
9a9e90a re-injected these verbatim, so the local stack dropped every
segment whose checksum MSS clamping didn't happen to rewrite: the
SYN/SYN-ACK got through (clamping recomputes them) but the bare ACK,
data, and FIN were dropped for a bad checksum, leaving the listener
stuck in SYN_RCVD.
Recompute the TCP/UDP checksum for self-addressed packets on the hairpin
path before re-injection, completing the self-delivery 9a9e90a started
(which only covered ICMP and the TCP handshake). Linux is unaffected: it
loops self-traffic via lo before the TUN, so the hairpin branch never
fires and checksums are already valid.
Confirmed on macOS: a self-connect that previously timed out now
completes in ~9ms with payload delivered.
The linux/macos/windows package workflows each publish a
checksums-<platform>.txt sha256 file with their release artifacts, but
the OpenWrt workflow attached only the .ipk files with no checksum
coverage. Generate checksums-openwrt.txt over the .ipk outputs using the
same sha256sum idiom as the other platforms and add it to the release
file set.
Add a flake that builds all four binaries (fips, fipsctl, fips-gateway,
fipstop) on Linux and macOS, pinning the exact toolchain from
rust-toolchain.toml (1.94.1 + rustfmt/clippy) via fenix so Nix builds
match CI and the AUR/Debian packaging.
Wire up the build-time native deps the source tree needs: pkg-config and
bindgenHook (libclang) for the rustables/libdbus-sys bindgen step, and
dbus for bluer's BLE support. autoPatchelfHook rewrites the binary RPATHs
so the daemon resolves libdbus-1.so.3 and libgcc_s.so.1 from the Nix store
at runtime — without it `fips` fails to load on NixOS, which has no global
/usr/lib.
Outputs: packages.{default,fips}, apps for each binary, checks.fips, and a
devShell with the pinned toolchain plus cargo-edit. Tests are skipped in
the package build since they exercise TUN devices, raw sockets, and mDNS
that aren't available in the sandbox, mirroring the AUR/Debian packaging.
Verified end-to-end in a pure Nix store (nixos/nix container): nix build,
nix flake check, and running all four binaries succeed against the
committed flake.lock.
Documented across the install and developer docs: a Nix / NixOS section in
packaging/README.md, the from-source guide in docs/getting-started.md
(noting the flake produces binaries only, with NixOS system integration
through the system configuration rather than the installer), the CHANGELOG,
README, CONTRIBUTING, and the v0.4.0 release notes.

A packet destined for our own mesh address reached the TUN reader on
macOS (utun egresses self-traffic into the daemon despite the lo0 host
route) and was pushed onto the mesh outbound path, where it was dropped
for lack of a session/route to self. Hairpin self-addressed packets back
to the TUN writer instead, so ping6 and connections to our own
<npub>.fips address are delivered locally.
On Linux the kernel already loops self-traffic via `lo` before it reaches
the TUN, so the branch never fires there; the check is kept unconditional
as a daemon-level delivery invariant and to keep it covered by Linux CI.
The fips build runs bindgen (via the rustables crate that powers the LAN
gateway's nftables bindings), which needs libclang.so at build time.
makepkg -s installs only declared makedepends, so without clang the AUR
build panics with "Unable to find libclang". Add clang to the makedepends
of both PKGBUILD and PKGBUILD-git so makepkg installs it and AUR users
get the dependency. Surfaced by the always-on aur-build CI job.
Bring the source tree to its finished v0.4.0 content state ahead of the
release candidate. Documentation, changelog, release notes, and
packaging metadata only; no code or version-string changes.
CHANGELOG.md: backfill the operator-visible changes that landed since
v0.3.0 (the show_metrics scraper query and fipsctl stats metrics, the
discovery dedup-cache-full counter, the off-rx_loop control read
surface and its new daemon-resolved fields, the fipstop TUI overhaul,
the TCP inbound cap now honoring max_connections, host-map hot-reload,
log-noise demotions, and the net bug fixes), topic-grouped rather than
replayed per commit; intra-cycle fixes folded into their feature
entries; the duplicate Unreleased Fixed section merged into one.
Release notes: author docs/releases/release-notes-v0.4.0.md to the
operator-upgrade bar and mirror it byte-for-byte into the root
RELEASE-NOTES.md. Attribute each feature to its author in Contributors
(Nym transport and the mixnet demo to @oleksky, opt-in mDNS LAN
discovery to @mmalmi).
README.md: add the Nym transport to the support matrix (Linux, macOS,
Windows; OpenWrt pending verification), the multi-transport bullet, and
the "What works today" list; fold mDNS LAN discovery into the existing
Nostr-discovery bullets; refresh the status narrative to v0.4.0 over a
global, public test mesh.
packaging/common/fips.yaml: add commented Nym transport and mDNS LAN
discovery example stanzas with verified field names and defaults.
Cargo.toml: add homepage, keywords, and categories crate metadata.
docs/reference: update the cli-fips version example to the released
form; document the new control-socket output fields and the typed
RejectReason families in control-socket.md; sync cli-fipstop.md with the
overhauled TUI keybindings.
poll_lan_discovery's comment said Noise XX, but LAN-discovered peers dial over
UDP through initiate_connection, which uses Noise IK (IK at FMP). compute_mesh_size's
header comment still described the obsolete sum-of-disjoint-subtrees estimate;
the function OR-unions every connected peer's inbound filter plus self and
estimates cardinality once (matching the body comment). Comment-only, no
behavior change.
Pre-cut documentation pass for the 0.4.0 release, verified against current source.
Corrections:
- fipsctl: stale 'show identities'/'show node' -> 'show status'
(host-a-service, run-as-unprivileged-user)
- mesh address derivation: first 16 bytes of SHA-256(pubkey) with the leading
byte set to 0xfd, not a fixed fd97: prefix (reach-mesh-services,
ipv6-adapter-walkthrough)
- gateway control socket mode 0660 -> 0770 (troubleshoot-gateway)
- Tor example: add advertised_port: 8443 so the published port matches the
prose (enable-nostr-discovery)
- bloom mesh-size estimate rewritten to the OR-union-of-peer-filters algorithm;
plus mtu deep-link, gateway pool wording, and a NAT failure-mode line
- examples: delete orphaned nostr-rs-relay config, accept inbound to the local
8443 TCP listener, fix fd::/8 -> fd00::/8 typos, dotless wireguard alias
Additions:
- new Nym mixnet transport section (fips-transport-layer) and the architecture
transport list
- new LAN/mDNS discovery section (fips-nostr-discovery)
- reference docs: Nym transport, LAN discovery, and new control/stats surfaces;
drop ble from the connect transport list
