The tray used a fixed sample for the data-path column, so longer relay names wrapped and made device rows uneven. Measure each rendered path and retain the widest value, then render path labels without wrapping. Replace direct/via words with embedded Phosphor route icons while preserving transport, relay name, hop count and explanatory tooltips. The app already ships the font; keep its setup in one function and verify registration alongside a long-relay-width regression test. No wire or stored-state changes. Checks: cargo fmt --all -- --check; cargo clippy --locked --workspace --all-targets -- -D warnings; cargo test --locked --workspace --all-targets.
Using an exit node could destroy direct peer connections: the agent's UID
bypass protected outbound routing, but reverse-path checks look up replies
without that UID and selected the overlay default. A real-host A/B check
confirmed that relaxing only strict reverse-path filtering restored direct
connections and exit HTTP traffic; the diagnostic host changes were removed.
Keep strict filtering and protect the Linux underlay with a dedicated masked
mark bit, 0x40000000. Mark the dedicated service UID in OUTPUT, save only that
bit in conntrack and restore it before PREROUTING reverse-path checks. Install
IPv4/IPv6 mark and UID main-table bypass rules before Tailscale's priorities;
leave application-specific and exit-default routing after them. Preserve
foreign mark bits, main-table routes and foreign firewall/policy rules.
Protect the first inbound TCP/UDP packet using bounded, locally owned socket
addresses/ports from /proc and an actual socket match. Refresh socket protection
before sending private transport negotiations and on discovery ticks, without
firewall writes for an unchanged socket set. Remote announcements never become
OS arguments. A failed refresh leaves active exit routing in place. Install
protection before routes, remove routes before protection, roll back partial
activation, and remove only exact interface tags, including legacy UID rules.
Reject strict kernel rp_filter without src_valid_mark with an actionable error;
never weaken filtering or change host sysctls. Document mark-aware Netfilter
requirements and provide the trusted ip6tables path in the NixOS module.
Other platforms retain their existing exit implementation. Peer wire formats,
identity derivation, local IPC and persistent storage are unchanged.
Make the tray devices grid fill and shrink with the window, constrain the first
cell and give remaining width to traffic plots. Keep displayed end-to-end
protocol and its short encryption tooltip consistent, independent of carrier
protocol. Move handshake/session age into its own column beside the existing
iroh control RTT. Use stable per-device hover identities and concise tooltips;
missing protocols/measurements remain explicit rather than invented.
Validation on Linux through nix develop:
- cargo fmt --all -- --check
- cargo clippy --locked --workspace --all-targets -- -D warnings
- cargo test --locked --workspace --all-targets: 529 passed, 3 ignored;
inherited TSUNAGI_CONTROL_SOCKET and TSUNAGI_CONTROL_GROUP were unset
- explicit privileged kernel regression: 1 passed, using disposable namespaces,
real TCP/UDP IPv4/IPv6, strict kernel and Netfilter RPF, first inbound packets,
dynamic UDP binding, application exit routing/IPv6 blocking, repeated apply
and exact cleanup with foreign Tailscale-priority rules retained
- headless egui grid/scroll-area rendering at multiple sizes and control RTT,
mark masks/order, passive socket parsing, partial failure and cleanup tests
- git diff --check
Earlier iterations caught rtnetlink family API and nonexhaustive initializer
errors, Clippy warnings, egui's implicit minimum column width, and kernel-test
fixture issues (wildcard echo source, blocked IPv6 neighbour discovery and a
closed child stdout pipe). Corrected before final checks; the stdout-only test
fix was checked with fmt, Clippy and the explicit kernel regression afterward.
Native tray rendering and macOS/Windows checks were not run. The running host
agent was not replaced or restarted. Requested release tag: v0.1.0-rc.32.
Offline devices reserved names and IPv4 addresses indefinitely, leaving stale
members in the device history. Give every authenticated network participant
the same right to retire another device's observed signed claim without an
owner, quorum, permanent identity ban or secret change.
Add a separately signed retirement containing the target's original signed
claim as proof. Verify both signatures and network scopes, retain the strongest
proved cutoff per target with deterministic ties, and suppress claim versions
at or below it in membership, hostname ownership and IPv4 allocation. Keep the
old signed records and range agreement, and retain markers after a newer claim
returns so old replicas cannot resurrect obsolete reservations. A returning
device signs a newer claim, allocates against current holders and resets its
previous hostname priority rather than taking a reused name with an old time.
Commit local retirement and the requester's author counter atomically before
announcing it; receivers persist proofs before applying them. Bound history to
1024 targets by default, reject additional targets without evicting protection,
and treat corrupt or over-limit mandatory storage as an explicit error. Repeat
bounded marker batches with a per-session rotating cursor so queue pressure
cannot indefinitely starve later markers. Exclude retired claims and cached
hints from history-derived discovery without preventing a fresh authenticated
device from returning.
Expose Agent::forget_node through the shared local control API. CLI command
tsng network forget-node accepts exact network names, full ids or unique id
prefixes, and exact node hostnames, ids, prefixes or overlay IPv4 addresses.
Ambiguous selections change nothing. Recheck the observed version and refuse
self, online nodes, the selected exit node and absent or changed claims.
Add Forget with an identity confirmation to offline tray device rows. Widen
Show devices to 1440x640 with an 800x400 minimum to fit its contents.
Control ALPN/version advances to tsunagi/ctrl/7 and local IPC to 21; upgrade
all peers and restart the agent with matching CLI/tray clients. Data ALPN 5,
network identity derivation, handshake encoding and existing record signing
bytes remain unchanged. SQLite schema 9 adds retirement storage while retaining
identity, secrets, settings and signed claims. Document behavior and limits.
Validation on Linux through nix develop:
- cargo fmt --all -- --check
- cargo clippy --locked --workspace --all-targets -- -D warnings
- cargo test --locked --workspace --all-targets: 519 passed, 2 existing ignored
tests; inherited TSUNAGI_CONTROL_SOCKET and TSUNAGI_CONTROL_GROUP were unset
- git diff --check and the built CLI forget-node help
Tests use real iroh authentication and SQLite. Cover restart, stale-replica
recovery, equal rights and network isolation, hostname reuse and return, twelve
marker batches through a two-message queue, malformed signatures and proofs,
invented future cutoffs, deterministic merge, capacity, migration and injected
counter-write rollback, selectors and cleanup through two real CLI processes.
Earlier iterations caught a private test API, a collapsible tray conditional
and a crash-based CLI test waiting for QUIC's idle timeout; corrected before
the final successful suite. Manual tray rendering, macOS/Windows, privileged
TUNs and public-network traversal were not run. The requested RC tag is
v0.1.0-rc.31; no push was requested.
The tray called the end-to-end tunnel proto and the current route link, then put the tunnel handshake age beside the route. A valid wg tunnel over a tcp-tls transport consequently looked like contradictory state. The terminal status used similarly terse wording.\n\nThe tray now separates end-to-end from data path, renders direct paths as direct over TRANSPORT, keeps handshake or uptime beside the tunnel, and explains both layers in hover text. Terminal status uses the same end-to-end tunnel, data path, transport detail, and control path vocabulary. Routing, protocol selection, IPC, and wire behavior are unchanged.\n\nPresentation tests cover wg over tcp-tls, tcp-tls uptime, relayed and missing paths, a missing handshake, and offline devices. The WireGuard broadcast checksum test uses the current slice-array iterator spelling required by Clippy; its behavior is unchanged.\n\nChecks: cargo fmt --all -- --check; cargo clippy --locked --workspace --all-targets -- -D warnings; cargo test --locked --workspace --all-targets with TSUNAGI_CONTROL_SOCKET removed from the test environment so integration agents use their temporary control sockets. All passed on Linux.
A tunnel no longer depends on the kind of link under it. The relay hub keeps
one forwarding table per network instead of one per protocol, the envelope
names the end-to-end protocol, and a neighbour reached over several kinds of
transport is sent to over the best open one. A member in the middle needs no
protocol in common with either end. Which protocol a pair runs is settled by
the lower endpoint id's announced order, so both ends agree without asking.
A direct link that comes up later is shorter than the path through others, so
traffic moves to it with the same logical link.
The agent now answers "is it online" once: a live control session or any data
path. Members and peers report how they are reached (direct over a named
transport, relayed through a named member, or no data path yet), and `tsng
status` and the tray both read that instead of a session list and a WireGuard
handshake respectively.
A hostname belongs to whoever claimed it first. A claim carries the time its
author first claimed the name, signed with the record, and replicas order by
(time, id) so every member names the same holder. A later claimant keeps
working by address, is not found by the name, and is told so in its status,
`tsng status`, the tray and a HostnameTaken event.
Wire change: control and data ALPN 5, control PROTOCOL_VERSION 5, envelope
version 2, signing domain v3, state schema 7, local control protocol 18.
Upgrade every member together.

IPv6 has no way through an exit node, so the same policy rules get an
unreachable default for IPv6 instead of leaking it. The tray shows a green
icon in the tile corner while an exit node is in use, with a one-line
confirmation to stop it; confirmations are shortened.

A member can offer itself as an exit node per network (off by default); it is
announced over the control channel (ctrl/4) once its iptables masquerade and
forward rules are in place, with a warning when kernel forwarding is off. A
device picks one member as its exit node via policy routing, with the agent's
own uid exempt from the tunnel; if the exit node disappears the rules stay
and traffic is dropped, loudly reported. CLI: `network exit-node`,
`exit-node`; tray: tile checkbox, warnings and a per-device icon with
confirmation. Linux only.

The tray process holds only the icon and starts the same binary with
--window on Open; the window ends when closed, which works on Wayland where
a window cannot be hidden. The devices table now names devices as
hostname (id5), leaves out this device and counts the others.

- The devices window now shows a single device table instead of a separate
"connected" box and an easily-missed "offline" box below it. Every endpoint
known from a live tunnel or the signed membership appears, online first;
offline rows show name and address with dashes for the live columns. The
table fills the window and scrolls, so nothing hides off the bottom.
- Clicking an online peer's name copies hostname.network (the FQDN) so it
resolves; a name without a hostname copies its short id.
- Copy feedback no longer appends "Copied" text (which reflowed the table for a
second). The field just flashes green and fades back over a second, with no
change to its text or width.

The connected-peers rate and sparkline shared one grid cell, so the plot still
moved right as the rate text grew (e.g. "1.0 kB/s"). They are now two separate
grid columns — the plot column starts at the same x on every row, since grid
columns align.
The devices window also gets its own pkts/bytes toggle, bound to the same unit
setting as the main window so the two stay in step.

- Bundle egui-phosphor (pinned to egui 0.31) and register its glyphs, so the
icon buttons render real icons instead of tofu: refresh, shuffle (generate
secret), pencil/check/x (rename host), copy (Copy secret).
- Copying is now the field itself, not a separate button: clicking the
shortened device id, the network name, the network id, a range or an address
copies the full value and the field flashes green "Copied" for a second
(tracked in egui temp memory, so it clears itself). The standalone copy
buttons are gone.
- In the devices window the connected-peers "rate / plot" column put the rate
and the inline sparkline in a shared row, so the plot shifted as the rate
text changed width ("0 B/s" vs "1.1 kB/s"). The rate now sits in a
fixed-width, truncating cell, so the plot stays put.

Replaces the in-tile collapsing peer list with a "Show devices" button that
opens a separate, normal-sized window per network, and fills in the rest of the
feedback.
Main window:
- A global show: pkts/bytes toggle; all rates and sparklines follow it.
- Sparklines now reserve their space always (fixed height, "no data yet"
placeholder) so the layout no longer jumps when data arrives, and each one
overlays its peak (top-left) and current value (bottom-right) with units.
- Device id has a copy button; the hostname is editable in place (✎ → edit →
✔/Enter sends SetHostname); network name, range and address copy on click.
- The Leave button is a neutral red. Per-tile "Show devices" opens the detail.
Devices window (a separate egui viewport per network):
- Network summary: id (copy), active/broadcast, range, this device's address,
candidates, relay fwd/via/recv, dial/handshake failures.
- A larger network traffic sparkline.
- Connected peers in a table: hostname when known (else short key), protocol,
address, handshake age formatted (s/m/h/d), tx/rx packets, tx/rx bytes, and
current rate with an inline sparkline. Names and addresses copy on click.
- Offline members listed below with address and failed-dial count.
Agent: a SetHostname command (over the existing ipc) backs the in-place rename.
Traffic sampler now tracks both packet and byte rates; the toggle selects which.
Deferred: a "copy secret" button on the tile — the secret is deliberately not
exported to the GUI (secrets never leave the agent), so it needs a small local
secret-export ipc, which is the next step.
Builds and is clippy-clean (-D warnings) on macOS; the UI has not been run in
this headless session.
