* [iface] Drop redundant device dump in kernel configure()
wgctrl.ConfigureDevice already returns an error when the interface is
missing, so the preceding wg.Device() existence check is redundant. That
check dumps the entire device (all peers) on every configure() call,
making it O(peers) per call and turning bulk peer insertion into
O(peers^2): inserting N peers one by one re-parsed the whole growing peer
list N times. Removing it keeps each peer write constant-time regardless
of how many peers are already configured.
* [iface] Cache WireGuard stats to collapse per-peer device dumps
Each peer runs a WGWatcher that polls GetStats(), and every call dumps
the whole device, so with N peers the watchers perform O(N) full dumps
per poll cycle (O(N^2) work) while each keeps only its own peer's entry.
Wrap the kernel and userspace configurer GetStats() in a short-TTL cache
with singleflight: the staggered per-peer calls share a single device
dump per window and concurrent misses collapse into one dump. The kernel
and userspace WireGuard APIs have no per-peer stats query (a get always
returns the whole device), so a shared cached snapshot avoids the
repeated full dumps.
* Ignore .claude directory
Restore the pre-split native, sudo-based run for the Linux Client / Unit
job: build with the privileged tag and run under sudo, matching the darwin
job. Excludes the dockertest harness (client/testutil/privileged) so it does
not recurse into a container spawn. The Docker privileged job is kept as-is.
* [client] Fix race between WG watcher initial handshake read and endpoint config
The watcher's initial handshake read ran in a separate goroutine with no
ordering guarantee relative to the WireGuard endpoint configuration, so it
would sometimes race with the peer being added to the interface. Split
enabling into a synchronous PrepareInitialHandshake, called before the
endpoint is configured, and an EnableWgWatcher that only runs the
monitoring loop, making the baseline read deterministic and keeping it
correct for reconnects where the peer's WireGuard entry survives.
* [client] Skip WG watcher disconnect callback when context is cancelled
A superseded or cancelled watcher whose handshake-check timer fires before
it observes ctx.Done() would still invoke onDisconnectedFn, tearing down a
now-healthy connection. Re-check ctx before firing the disconnect and
handshake-success callbacks and stand down silently if it was cancelled.
apply() compared several *bool/*int ConfigInput fields against the
Config fields by pointer identity instead of by value, so any
non-nil input always looked "changed" and triggered a spurious log
line plus an unconditional config rewrite even when the value was
unchanged.
* [management, client] Add management-controlled client metrics push
Allow enabling/disabling client metrics push from the dashboard via
account settings instead of requiring env vars on every client.
- Add MetricsConfig proto message to NetbirdConfig
- Add MetricsPushEnabled to account Settings (DB-persisted)
- Expose metrics_push_enabled in OpenAPI and dashboard API handler
- Populate MetricsConfig in sync and login responses
- Client dynamically starts/stops push based on management config
- NB_METRICS_PUSH_ENABLED env var overrides management when explicitly set
- Add activity events for metrics push enable/disable
* Remove log line
* [management] Fix peer update test for MetricsConfig in NetbirdConfig
Update TestUpdateAccountPeers assertions: NetbirdConfig is no longer
nil in peer update responses since it now carries MetricsConfig even
when STUN/TURN config is absent.
* Regenerate proto files with protoc v7.34.1
* [management] Read metrics push setting in Postgres account query
getAccountPgx omitted settings_metrics_push_enabled from its hand-written
SELECT and Scan, so the toggle was always read back as false on Postgres
and never reached clients.
* [client] Fix metrics push getting stuck off after engine restart
Engine restarts (backoff retries within the same login session) cancel
e.ctx, which the push goroutine's lifetime was tied to. The goroutine
died silently but ClientMetrics.push stayed non-nil since only an
explicit stop clears it, so the next UpdatePushFromMgm call saw a
"push already running" state and never restarted it.
Give the Engine its own metricsCtx sourced from ConnectClient.ctx,
which outlives engine restarts, so handleMetricsUpdate stops tying the
push to the wrong-scoped context. Additionally make ClientMetrics.push
an atomic.Pointer that the push goroutine clears via CompareAndSwap on
exit, so the tracked state can never drift from the goroutine's actual
lifetime regardless of which context a future caller passes in.
* [management] Regenerate OpenAPI types with oapi-codegen v2.7.1
types.gen.go was regenerated with a stale local v2.6.0 binary,
causing the CI git-diff check against generate.sh's pinned v2.7.1
to fail.
* [client] Skip firewall ruleset rebuild when config is unchanged
ApplyFiltering rebuilt every peer and route ACL and flushed the firewall
on every sync, with no guard for an unchanged configuration. Management
re-sends the same network map far more often than it actually changes
(account-wide updates, peer meta churn), so on busy accounts this is the
dominant client-side cost of redundant syncs — especially with a large
route set and a userspace firewall.
Hash the inputs ApplyFiltering consumes (peer rules, route rules, the
empty flag and the dns-route feature flag) and skip the rebuild + flush
when the hash matches the last successfully applied update. Mirrors the
guard the DNS server already uses (previousConfigHash). The hash is only
recorded after apply and flush both succeed, so a failed update is not
skipped on the next (possibly identical) sync and gets a chance to
reconcile the firewall state.
* [client] Include config hash in ACL skip debug log
* [client] Include RoutesFirewallRulesIsEmpty in firewall config hash
* [client] Add benchmarks for firewall config hash computation
Peer connection timing fields (signaling_to_connection_seconds) can
legitimately exceed 5 minutes during long reconnections; the previous
300 s cap caused valid data points to be rejected.
* fix(mgm): report management unhealthy while Sync stream is failing
The health probe (IsHealthy) only checked the gRPC transport and a
GetServerKey call. GetServerKey succeeds even when the peer cannot sync
(e.g. the server returns "settings not found"), so the probe kept marking
management Connected while the Sync stream failed in a tight retry loop —
pinning the status to "Connected" forever despite no sync ever succeeding.
Track the last Sync stream error and have IsHealthy consult it, so a
healthy transport is no longer enough to report the connection healthy.
* fix(mgm): record disconnected state when sync stream setup fails
The connectToSyncStream failure path in handleSyncStream returned early
without updating syncStreamErr, so the client could still report healthy
even when stream setup failed. Mirror the receiveUpdatesEvents error path
by calling notifyDisconnected and setSyncStreamDisconnected.
* [client] Wait for signal receive watchdog to stop before reconnect
The per-stream watchReceiveStream goroutine was started fire-and-forget
and never joined. On reconnect a lingering watchdog could still flip
shared client state (receiveStalled, the disconnect notifier) on the
freshly established stream, since cancelStream only cancels its own
stream context.
Track the watchdog with a WaitGroup and wait for it to exit (after
cancelling its stream) before the operation returns, so each reconnect
starts with no stale watchdog.
* [client] Bind signal receive probe to the stream context
The watchdog probe reused the generic Send, which derives its per-attempt
timeouts from the long-lived client context, so cancelStream could not
interrupt an in-flight probe. After joining the watchdog on reconnect,
watchdogWg.Wait() could then block for the full send-attempt chain.
Split Send into a context-aware send and pass the stream context down
through sendReceiveProbe, so cancelStream aborts any in-flight probe and
the watchdog exits promptly.
* [client] categorize root/system-mutating tests behind a privileged build tag
Tests that need root or mutate host state (nftables/iptables/DNS, TUN/WireGuard
interfaces, routes, eBPF, SSH/service install) are now gated behind a
//go:build privileged tag. The default `go test ./client/...` runs as a non-root
user with no sudo and leaves host networking untouched; mixed files were split so
pure-logic tests stay in the default suite.
A self-hosting ory/dockertest/v4 harness (client/testutil/privileged) runs the
privileged suite inside a --privileged --cap-add=NET_ADMIN container via
`make test-privileged`; a DOCKER_CI=true guard skips the spawn when already inside
the container. Added `make test-unit` for the host-safe run.
* [client] add PRIV_RUN/PRIV_PKGS filters to the privileged test harness
The dockertest harness now reads two optional env vars when building the
in-container `go test` command: PRIV_RUN adds a -run test-name filter and
PRIV_PKGS overrides the package list. Both empty reproduce the full privileged
suite, so CI and `make test-privileged` behave as before. Lets a developer run a
single privileged test in the container, e.g.:
PRIV_RUN=TestNftablesManager PRIV_PKGS=./client/firewall/nftables/... make test-privileged
* [client] fix unused-helper lint after the privileged test split
Splitting privileged tests into *_privileged_test.go left their shared helpers in
the untagged files, so in the default (no-tag) build they had no callers and
golangci-lint flagged them as unused.
Moved the privileged-only helpers into the privileged files next to their callers
(generateDummyHandler; createEngine/startSignal/startManagement/getConnectedPeers/
getPeers + kaep/kasp; (*mockDaemon).setJWTToken). Annotated the shared routing-test
fixtures that must stay untagged for cross-platform compilation with //nolint:unused
(systemops_bsd expected* vars, ensureIPv6DefaultRoute on bsd/windows,
loopbackIfaceWindows), matching the existing linux variant.
* [client] fix privileged test CI failures and run the harness on macOS
The host-safe unit run dropped sudo but two privileged test groups were
never tagged, and the Docker privileged job silently never ran the suite:
- Gate the ssh/server PrivilegeDropper command-construction tests behind
the privileged tag (they require root to target a different UID); split
them into executor_unix_privileged_test.go.
- Tag sharedsock raw-socket tests privileged (need CAP_NET_RAW).
- Fix the Docker job command: nested single quotes around the build tags
closed the sh -c wrapper early, dropping the go list package set and the
privileged tag, so go test ran on the empty repo root. Use double quotes.
Make the self-hosting harness usable from a dev Mac:
- Build it on darwin as well as linux; it only drives Docker.
- Resolve the active docker context endpoint into DOCKER_HOST when the
default /var/run/docker.sock is absent (Docker Desktop, Colima, OrbStack).
- Rename the misspelled containerGoModache constant to containerGoModCache.

* [ci] Run privileged-tagged tests on darwin, windows and freebsd
The privileged build tag split moved root/system-mutating tests behind
//go:build privileged, but only the linux docker job was given the tag.
The native darwin (sudo), windows (PsExec64 -s) and freebsd VM runners
already have the required privileges, so add the privileged tag there too
to keep CI running the same set of tests as before the split.
* [ci] Exclude dockertest harness from the darwin privileged run
The privileged tag now compiles client/testutil/privileged on darwin, whose
TestRunPrivilegedSuiteInDocker spawns a container the macOS runner has no
Docker for. Exclude the harness package from the darwin list, matching the
linux job, so the privileged tests run in place without a container spawn.

* [client] Remove peer deletion on lazy activity detection
Updated WireGuard dependency with a patch and removed the RemovePeer
call on lazy activity detection to force a new handshake initiation
to the updated endpoint. This also flushed the staged queue, dropping
the first packet.
Since UpdatePeer (called after ICE/relay negotiation) triggers
SendStagedPackets via IpcSet/handlePostConfig, the peer removal is
no longer necessary. The staged packet survives and the handshake
is initiated on the real endpoint automatically.
This also eliminates the transient state where the peer's endpoint
and routes were absent between the lazy idle and connected states.
* Update WireGuard dependency
* Update WireGuard dependencies
* Update WireGuard dependency
* peer/status: move relay-state reads off the main mux
GetRelayStates held d.mux (RLock) while calling into the relay
Manager (RelayStates/RelayConnectError/ServerURLs). Those calls can be
slow or block on the relay manager's own locks while it is reconnecting,
which kept the central Status mutex held and stalled every peer state
writer (UpdatePeerState, ReplaceOfflinePeers, etc.) contending for it.
Guard relayMgr/relayStates with a dedicated muxRelays mutex and release
it before invoking the relay Manager, so the relay read path no longer
contends with the hot peer-state writers on d.mux.
* peer/status: clone relay states in nil-manager path
Return a cloned snapshot of d.relayStates when relayMgr is nil so callers
cannot mutate the shared cached state, matching the non-nil path.
* [client] Filter link-local and multicast from network addresses
Skip IPv6 link-local and multicast addresses when building the peer
network_addresses list on non-iOS platforms, matching the existing iOS
behavior. A flapping NIC's link-local address otherwise churns the peer
meta on every interface up/down.
* [client] Skip engine restart when default route is unchanged
After the network monitor's debounce window, re-check the default next
hop before triggering a client restart. A flapping NIC that returns to
the same default route no longer forces a restart, avoiding redundant
sync stream reconnects and peer meta churn.
* [client] Exclude own overlay address from reported network addresses
The peer's own WireGuard overlay address (v4 and v6) was reported in
network_addresses. As the interface comes and goes during reconnects it
churned the peer meta on the management server. Drop it in
GetInfoWithChecks, matching the IP regardless of prefix length since the
engine knows the overlay address with the network mask while the
interface reports it as a host address.
* [client] Treat missing default route per protocol in next-hop check
A failed GetNextHop lookup is now treated as an absent route (zero
Nexthop) and compared per protocol, instead of forcing a restart. In a
single-stack network the missing IPv6 default route no longer counts as
a change on every debounce, which previously defeated the unchanged-route
check.
* [client] Make next-hop check injectable for network monitor tests
Move the next-hop comparison behind a NetworkMonitor field set by New(),
so tests can supply a stub instead of hitting the host's real default
route. Fixes the Event/MultiEvent tests hanging after the unchanged-route
check was added.
* Revert "[client] Make next-hop check injectable for network monitor tests"
This reverts commit 88a9d96e8f.
* Revert "[client] Treat missing default route per protocol in next-hop check"
This reverts commit 0fb531e4bc.
* Revert "[client] Skip engine restart when default route is unchanged"
This reverts commit a071b55f35.
* [client] always clean up on Engine.Start failure via defer
The rosenpass init paths (NewManager/Run) returned without calling
e.close(), leaking the WireGuard interface and other partially
initialized state on failure. Per-branch cleanup was easy to miss when
adding new early returns.
Convert Start to a named error return and tear down via a single defer
that calls e.close() whenever err != nil, removing the scattered
per-branch close() calls (including the redundant one in initFirewall).
* [client] make Engine single-use and guard against double Start
Create the run context once in NewEngine instead of in Start. This
keeps e.cancel valid for the engine's whole lifetime, so Stop can
cancel a Start that is blocked waiting on the network while holding
syncMsgMux: Stop now cancels before taking the lock, unblocking that
Start so it can release the mutex.
Reject re-entry into Start: a non-nil wgInterface means a prior Start
already ran (ErrEngineAlreadyStarted), and a cancelled run context
means the engine was stopped (ErrEngineAlreadyStopped). Both checks run
before the cleanup defer so a duplicate call cannot tear down the
running engine's state.
* [client] let engine context unblock WaitStreamConnected
WaitStreamConnected only watched the signal client's own context, which
derives from the parent engineCtx rather than the engine's run context.
A Start blocked here (signal stream not yet up) could therefore not be
released by Engine.Stop, since Stop only cancels the engine's run
context.
Pass a context into WaitStreamConnected and select on it too, and have
the engine pass e.ctx, so Stop cancelling e.ctx unblocks a parked Start.
Update the Client interface, the mock, and callers accordingly.
* [client] fix Start/Stop race by making the run loop own engine shutdown
ConnectClient.Stop stopped the engine directly while the run loop's
backoff cycle could still be starting an engine, so Engine.close raced
Engine.Start (e.g. firewall setup reading wgInterface while close nils
it). embed.Client.Start's rollback only avoided a deadlock by cancelling
before Stop; the race itself remained and was caught by -race.
Make the run loop the sole owner of engine shutdown: derive the run
context in NewConnectClient, and have Stop cancel it and wait for the
loop to exit (skipping the wait when the loop never ran) instead of
calling engine.Stop. The loop now always stops the engine on its way
out, dropping the unsynchronised wgInterface check it used to guard that
call. Self-calls from within the loop use runCancel to avoid waiting on
themselves.
embed keeps a defensive pre-Stop cancel(); the daemon's cleanupConnection
gets a TODO to adopt Stop() rather than stopping the engine in parallel.
* [client] init context state in engine tests
Engine tests built the engine context with context.WithCancel(
context.Background()), omitting CtxInitState. Now that the run context
is created in the constructor, the wgIfaceMonitor goroutine can reach
triggerClientRestart during teardown, which calls CtxGetState and
panics on the missing state. Real entry points (up, embed, service)
always CtxInitState; only the tests skipped it.
* [client] interrupt connect backoff on context cancel
The run loop retried with a raw ExponentialBackOff, so a backoff sleep
ignored context cancellation. Now that ConnectClient.Stop waits for the
run loop to exit, a cancel landing during a sleep would block Stop for
the full interval (up to MaxInterval). Wrap the backoff with the run
context so Retry returns promptly on cancel; the retry budget itself
(MaxElapsedTime) is unchanged.
* [client] bound WaitStreamConnected in signal client tests
The tests waited on WaitStreamConnected with context.Background() and the
client's own context was also Background, so a stream that never connects
would hang until the suite timeout. Pass a 5s timeout context and assert
StreamConnected afterwards so the tests fail fast with a clear reason.
* [client] fix WaitStreamConnected stale-channel race
The StreamConnected check and the wait-channel creation took the mutex
separately, so notifyStreamConnected could set the status and close/clear
connectedCh in between: the waiter then created a fresh channel nobody
would ever close and blocked forever. Also, the status read was unlocked
while notify wrote it under the mutex (a data race). Do the check and the
channel fetch in one locked section; drop the now-unused
getStreamStatusChan helper. Pre-existing bug, not introduced by this branch.
* [client] abort Start if context cancelled while waiting for signal stream
receiveSignalEvents blocks in WaitStreamConnected until the signal stream
connects or the context is cancelled. If Stop cancelled e.ctx while Start
was parked there, Start kept going: it started the remaining subsystems on
a cancelled context and marked a shutting-down engine as started. Return
the context error from receiveSignalEvents and propagate it from Start, so
the deferred cleanup runs and the cancellation reaches the caller.
* [client] clean up all started components on Start failure
Start's failure defer only called close(), which covers the wg interface,
firewall, rosenpass and port forwarding but leaves connMgr, srWatcher,
route/DNS/flow/state managers and the monitor goroutines running. A late
failure (e.g. the context-cancelled check after the signal stream) thus
leaked them.
Extract Stop's locked teardown into stopLocked (caller holds syncMsgMux,
does not wait on shutdownWg) and call it from both Stop and Start's defer.
The defer also cancels the run context first so goroutines started before
the failure unwind. Teardown order is unchanged.
The iOS PKCE login runs in the main-app process, decoupled from the network
extension (the extension's client context is torn down on login-required, which
would otherwise kill the WaitToken goroutine before the OAuth callback arrives).
Because it is decoupled, nothing aborted the flow when the user dismissed the
browser without logging in: WaitToken kept its loopback HTTP server bound to the
redirect port until the flow expired, so the next connect stalled trying to bind
the same port.
Make the Auth context cancellable and add Auth.Stop(), which cancels it. Cancelling
unblocks WaitToken, whose deferred server.Shutdown frees the port immediately. This
mirrors how Android's stopEngine() aborts login via the engine context.
NewAuthWithConfig now also derives a cancellable context; its only iOS caller uses
LoginSync (no interactive server), so behaviour is unchanged there.
* [client] fix iOS route-update reordering that black-holed IPv6 on exit-node disable
On iOS the route notifier delivered each prefix update from its own
fire-and-forget goroutine (notify -> `go func`), so Go provided no ordering
guarantee between consecutive updates. It also read currentPrefixes inside
that goroutine without holding the lock, racing the next OnNewPrefixes write.
On exit-node disable the core removes the default routes as two separate
prefix updates (0.0.0.0/0, then the synthesized ::/0). When the two
goroutines were reordered, the stale snapshot still containing ::/0 was
delivered last and clobbered the correct default-free one. iOS then kept the
::/0 default route on the tunnel with no exit node to carry it, black-holing
all IPv6 traffic while IPv4 recovered correctly.
Fix: deliver updates through a single worker goroutine fed by a buffered
channel, preserving production order, and snapshot the joined prefix string
under the mutex so it can't race a concurrent update. Buffered so producers
(which run under the route manager lock) don't block on the listener callback.
* [client] close iOS notifier delivery goroutine on Stop, unbounded queue
The delivery goroutine was never stopped, leaking on every engine
restart. Add Notifier.Close, called from the route manager Stop after
routing cleanup.
Replace the buffered update channel with a cond-driven linked-list
queue so route-update producers (running under the route manager lock)
never block when the listener callback is slow.
Expose a network-free login-required check backed by the in-memory status
recorder. Unlike IsLoginRequired(), which creates a fresh auth client and
performs a blocking network call, IsLoginRequiredCached() reports whether the
LAST observed management error was an auth failure (PermissionDenied/
InvalidArgument).
This lets the iOS connection listener detect a mid-session token expiry from
within onDisconnected during teardown without blocking on a slow or
unavailable network.
* Add iOS debug bundle support in Go
Thread cacheDir through NewClient -> RunOniOS -> MobileDependency.TempDir
so the iOS client can pass its sandbox-writable cache directory for
debug bundle zip file creation instead of os.TempDir().
Move log collection into platform-dispatched addPlatformLog():
- iOS: adds the file-based Go client log (with rotation, stderr/stdout
companions and anonymization handled by addLogfile) plus the Swift app
log (swift-log.log) written by the iOS app into the same log directory
- Other non-Android platforms: existing file-based log + systemd fallback
Narrow the debug_nonandroid.go build tag to !android && !ios so iOS no
longer attempts the systemd journal fallback.
Add a DebugBundle() entry point to the iOS Go client that generates a
bundle, uploads it and returns the upload key. It works with or without
a running engine: when the engine is up it reuses the live config, sync
response and client metrics; otherwise it loads the config from disk (or
the preloaded tvOS config). Guard the live config/ConnectClient behind a
state mutex since DebugBundle may run on a different thread.
* Include the iOS state file in the debug bundle
addStateFile() resolved the state path via ServiceManager.GetStatePath(),
which on iOS points at a hard-coded default that does not exist in the app
sandbox, so the state file was silently skipped.
Add an optional StatePath to GeneratorDependencies and use it when set,
falling back to the ServiceManager default otherwise. The iOS DebugBundle
passes the client's actual state file path (the App Group profile state),
matching the Android bundle which includes the state file.
* ios: enable sync response persistence for debug bundle
Turn on sync response persistence before starting the engine so
DebugBundle can include the network map. On iOS the store is disk-backed
(see syncstore) to keep the map out of the constrained process memory.
* ios: pass log file path through NewClient constructor (#6393)
Add logFilePath field to Client struct and expose it as a parameter
in NewClient so callers provide the Go log path at construction time.
Wire it into DebugBundle via GeneratorDependencies.LogPath so the
debug bundle includes client.log and swift-log.log regardless of
whether the bundle is triggered by the app or the management server.
Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com>
* ios: pass log file path to engine for remote debug bundles
RunOniOS started the engine with an empty LogPath, so EngineConfig.LogPath
was never set. Management-triggered (jobs) debug bundles read the log path
from the engine config, so they collected no client logs (client.log,
rotated logs, swift-log.log). The GUI path was unaffected because it passes
c.logFilePath directly to the bundle generator.
Thread c.logFilePath through RunOniOS into the engine config so remote
bundles include the client logs too.

* [client] propagate exit-node deselect to synthesized v6 (::/0) route
When a client deselects an IPv4 exit node, the auto-generated IPv6 default
route (::/0) was still selected and pushed onto the tunnel interface, even
though the user disabled the exit node. On an exit node without a real IPv6
egress this blackholes IPv6 traffic, and because clients prefer IPv6 (happy
eyeballs) it can break general connectivity.
Root cause: the synthesized v6 route gets a different NetID than its v4 base
(base + "-v6"). The route selector keys deselects by NetID and defaults
unknown NetIDs to selected, so the "-v6" entry was never matched by the v4
deselect. The effectiveNetID() mirror that solves exactly this is used by
HasUserSelectionForRoute and FilterSelectedExitNodes, but categorizeUserSelection
called the raw IsSelected(), bypassing it and mis-categorizing the v6 pair as
user-selected.
Add RouteSelector.IsSelectedForExitNode(), which applies effectiveNetID before
the selection check, and use it in categorizeUserSelection. IsSelected() is left
untouched so non-exit code paths don't make unrelated "*-v6" routes inherit v4
state. Adds regression tests for the v4/v6 deselect mirror and explicit-v6
override.
* [client] add DIAG logging to trace exit-node v6 (::/0) route filtering
Temporary diagnostics to find why a deselected v4 exit node's synthesized
::/0 route still reaches the tunnel. Logs the full install path: incoming
client networks, route-selector state before/after the management-driven
update, what updateExitNodeSelections deselects/selects, and per-route
KEEP/SKIP/DROP decisions in FilterSelectedExitNodes and applyExitNodeFilter.
To be reverted once the real root cause is confirmed from a client log.
* [client] clear orphaned v6 exit selection when v4 pair is toggled
Root cause of the leaking ::/0 route, confirmed from client logs: the
synthesized "-v6" exit route could stay explicitly selected in the persisted
route-selector state while its v4 base was deselected (selected=[...-v6],
deselected=[...v4base]). Because the v6 entry then has its own explicit state,
effectiveNetID stops mirroring the v4 base, so FilterSelectedExitNodes keeps
::/0 and it is installed on the tunnel even though the user disabled the exit
node. This happened because the iOS SDK's deselect only pairs the "-v6" sibling
via ExpandV6ExitPairs when the v6 route is present in the current routesMap; a
deselect at a moment it wasn't expanded left the v6 selection orphaned.
Fix at the selector write path so it is independent of routesMap timing: when a
v4 exit NetID is selected or deselected, clear any orphaned explicit state on
its "-v6" sibling (clearPairedV6Locked), unless the sibling is part of the same
batch (the deliberate ExpandV6ExitPairs case). The v6 then falls back to
inheriting the v4 base via effectiveNetID, so a v4 deselect also drops ::/0 and
a v4 select brings both back.
Adds regression tests: a stale explicit v6 selection is cleared by a later v4
deselect, and an explicit v6 select made in the same batch is preserved.
* [ios] compute route connection status in the bridge
The iOS bridge exposed a route's Network as a possibly comma-joined string
("0.0.0.0/0, ::/0" for a merged exit node) but no connection status, forcing
the UI to infer status by string-matching that joined value against peer
routes — which never matched for the merged exit node, leaving it stuck as
not-connected. Android already computes status in the core (findBestRoutePeer).
Mirror that here: add a Status field to RoutesSelectionInfo and compute it from
the connected peers' route tables, matching the route's primary prefix, a merged
exit node's extra v6 prefix, or a dynamic route's domain pattern (the key the
route manager records). The UI can now read the status directly.
* [client] remove exit-node v6 DIAG logging and tidy routeselector
Drop the temporary DIAG diagnostics added to trace the leaking ::/0 route
(the root cause is fixed and confirmed). Also reorganize routeselector.go so
the exit-node helpers (clearPairedV6Locked, isExitNode) sit next to the
exit-node code paths and MarshalJSON/UnmarshalJSON are grouped together.
* [client] mirror v4 exit selection onto v6 pair at write time
The synthesized "-v6" exit route shares its v4 base's NetID plus a "-v6"
suffix. Selection state was reconciled at read time via effectiveNetID, a
mirror that could only be applied on exit-node code paths, which forced a
parallel IsSelectedForExitNode() alongside IsSelected() and a clearPairedV6Locked()
orphan cleanup on every toggle. That machinery still missed the case observed
in the field: a persisted state with the v4 base deselected but its "-v6"
sibling explicitly selected (orphaned). Because effectiveNetID returns the v6
entry itself once it carries explicit state, and clearPairedV6Locked only fires
on a live toggle, the loaded orphan survived and the ::/0 route leaked onto the
tunnel despite the exit node being disabled, breaking IPv6 (happy eyeballs).
Treat the v4/v6 exit pair as a single toggle and keep state consistent at write
time instead. RouteSelector.SyncPairedSelection forces the "-v6" entry to match
its v4 base unconditionally, resetting any orphaned explicit state. The route
manager, which knows the route prefixes, computes the pairs (V6ExitMergeSet) and
calls it from updateRouteSelectorFromManagement before selection is read, so both
collectExitNodeInfo and FilterSelectedExitNodes see consistent state, including
pairs loaded from persisted selector state.
This removes effectiveNetID, IsSelectedForExitNode and clearPairedV6Locked; the
selector is literal again and no longer needs the "exit-node paths only" caveat.
HasUserSelectionForRoute and applyExitNodeFilter use the raw NetID.
Adds a selector test for SyncPairedSelection (including the orphaned-v6 case) and
a route-manager test reproducing the persisted-orphan scenario from the field log.
* [client] add DIAG logging to trace v6 exit-pair mirror
The write-time mirror did not eliminate the leak in field testing. Re-add the
DIAG diagnostics around the exit-node selection flow to capture a fresh trace:
- UpdateRoutes: incoming client networks, selector state before/after the
management update, and the networks remaining after FilterSelectedExitNodes.
- mirrorV6ExitPairSelections: the NetIDs present in this update and the v6 pairs
V6ExitMergeSet derives from them (reveals whether the v4 base and its ::/0 pair
are present in the same update so the pair can be matched).
- SyncPairedSelection: the base/paired state before and after the sync.
- FilterSelectedExitNodes / applyExitNodeFilter: per-route SKIP/KEEP/DROP and the
selection lookups behind each decision.
- updateExitNodeSelections / logExitNodeUpdate: categorization and deselect set.
Temporary; to be removed once the root cause is confirmed.
* [client] remove v6 exit-pair mirror DIAG logging
Drop the temporary DIAG diagnostics added to trace the v4/v6 exit-pair mirror.
The field log confirmed the write-time mirror keeps the pair consistent (the
::/0 route is only ever applied alongside its v4 base and is dropped on deselect),
so the diagnostics are no longer needed.
* fix(management): treat ci- builds as development for remote jobs
CI snapshot builds use a "ci-<sha>" version string that did not match
IsDevelopmentVersion, so the remote-jobs minimum-version gate rejected
them. Recognize the "ci-" prefix as a development build.
* fix(management): treat dev- builds as development for remote jobs
Dev snapshot builds use a "dev-<sha>" version string that did not match
IsDevelopmentVersion, so the remote-jobs minimum-version gate rejected
them. Recognize the "dev-" prefix as a development build, alongside the
existing "ci-" prefix.
* [client] Preserve posture checks on config-only sync updates
When management sends a MessageTypeControlConfig update (e.g. relay token
rotation), the SyncResponse carries no NetworkMap and no Checks. Moving the
updateChecksIfNew call after the nm == nil guard ensures posture checks are
only updated when a full network map is present, preventing relay token
rotation from silently clearing the previously applied posture check state.
* [client] Clarify posture check update logic with explicit comment
* [client] Extract NetBird config and sync persistence into helpers
Move the NetbirdConfig handling block out of handleSync into
updateNetbirdConfig and the sync response persistence into
persistSyncResponse, mirroring updateChecksIfNew. This flattens
handleSync and makes the individual update steps unit-testable.
* Persist sync response via pluggable store (disk on iOS)
The latest Management sync response (which carries the network map) was
kept in memory for debug bundle generation. On memory-constrained
platforms like iOS the network map can be large enough to matter.
Introduce a syncstore package with a Store interface and two backends:
a memory backend (the previous behavior) and a disk backend that
serializes the response to a file in the state directory. The backend
is selected per-platform at build time: disk on iOS, memory elsewhere.
The disk store clears any leftover file on construction so a fresh
store never reads stale data from an earlier run (e.g. another
profile's network map).
In the engine, drop the separate persistSyncResponse bool: the store is
only instantiated while persistence is enabled, and its presence is
what marks persistence as active. The store is also cleared on engine
close so the file does not linger on disk.
* syncstore: silence nilnil linter on "nothing stored" returns
Get returns (nil, nil) to signal that nothing is stored, which is part
of the Store contract and preserves the original behaviour. Annotate
both backends with //nolint:nilnil so golangci-lint does not flag it.
* syncstore: hold syncRespMux for the whole store Set/Get
Both handleSync and GetLatestSyncResponse snapshotted e.syncStore under
the read lock and then released it before calling Set/Get. That allowed
SetSyncResponsePersistence(false) or engine close to clear the store
mid-call. In particular a concurrent Clear()+nil followed by a late
Set could re-create the file that was just removed, defeating the
leak/lingering protection.
Hold syncRespMux for the duration of the store operation in both spots
so the store cannot be cleared while a Set/Get is in flight.
* syncstore: avoid StateDir "." when state path is empty
On mobile the state path may be empty (the engine tolerates a missing
state file). filepath.Dir("") returns ".", which would make a
disk-backed syncstore write into the working directory instead of
letting NewDiskStore fall back to os.TempDir().
Only set engineConfig.StateDir when path is non-empty.
* add SSO session extend flow (management)
Adds the management-server half of the SSO session-extension feature:
- New ExtendAuthSession gRPC RPC that refreshes a peer's session expiry
using a fresh JWT, validated through the same pipeline as Login but
without tearing down the tunnel or redoing the NetworkMap sync.
- Per-peer SessionExpiresAt timestamp on every LoginResponse and
SyncResponse so connected clients learn the deadline on the existing
long-lived stream, and admin-side changes (toggling expiration,
changing the expiration window) reach every peer within seconds.
- SessionExpiresAt(...) helper on Peer that derives the absolute UTC
deadline from LastLogin + the account-level PeerLoginExpiration
setting, returning zero when the peer is not SSO-tracked or expiration
is disabled.
The matching client-side consumer of these fields lands separately.
* encode SessionExpiresAt as 3-state on the wire
Previously the `sessionExpiresAt` field on LoginResponse, SyncResponse
and ExtendAuthSessionResponse was 2-state: a valid timestamp meant
"new deadline", and nil meant "clear". That conflated two distinct
meanings — "no info in this snapshot" vs "expiry is explicitly off /
peer is not SSO-tracked" — so a Sync push that legitimately couldn't
compute the deadline (settings lookup failed) would silently clear the
client's anchor and lose the warning window.
Three states now, encoded on the same field number (no .proto schema
churn — only comments and the server-side encoder change):
- nil pointer (field absent) → "no info"; client preserves anchor
- &Timestamp{} (seconds=0, nanos=0) → explicit "disabled / not SSO"
sentinel; client clears
- valid timestamp → new absolute UTC deadline
A new encodeSessionExpiresAt helper centralises the zero/non-zero
encoding and is shared by the Sync, Login and ExtendAuthSession
builders. The Sync builder still emits nil when settings are missing.
Login and ExtendAuthSession always carry an authoritative value.
The matching client-side decoder lands on feature/session-extend.
* add UserExtendedPeerSession activity event
ExtendAuthSession previously reused UserLoggedInPeer for its audit
record, which conflated two distinct user actions: a full interactive
SSO login (tunnel re-established, network map resync) versus an
in-place deadline refresh (tunnel untouched). Auditors reading the log
couldn't tell which one happened, and downstream dashboards/alerts on
"login" volume were polluted by routine extends.
Adds a dedicated UserExtendedPeerSession Activity (code 125,
"user.peer.session.extend") and switches ExtendPeerSession over to it.
The peer-extend audit trail is now distinguishable from interactive
logins.
* make ExtendAuthSession JWT-retry backoff cancellable
Skip the retry log and 200ms wait on the final attempt, and replace the
uncancellable time.Sleep with a select on time.After/ctx.Done so an
upstream cancellation aborts the wait instead of running it to
completion.
* [client] iOS: structured ResolvedIPs collection for domain routes
Replace comma-joined ResolvedIPs string with a gomobile-friendly
ResolvedIPs collection (Add/Get/Size), mirroring the Android bridge
in client/android/network_domains.go.
This allows the iOS app to match domain-route resolved IPs against
connected peer routes without parsing CSV strings, fixing the route
status indicator for dynamic (DNS) routes.
* [client] iOS: align dynamic route exposure with Android bridge
For dynamic (DNS) routes the Swift side previously received
"invalid Prefix" as the Network value, forcing UI code to special-case
that sentinel. The Android bridge uses Domains.SafeString() instead so
peer.routes entries (which also derive from Domains.SafeString()) match
directly. Mirror that here.
Also fix the resolved IP lookup: resolvedDomains is keyed by the
resolved domain (e.g. api.ipify.org), not the configured pattern
(e.g. *.ipify.org). Group entries by ParentDomain like the daemon does
in client/server/network.go, so wildcard route patterns get their
resolved IPs populated.
Detecting shutdown by inspecting the gRPC status code conflates a local
context cancellation with a server- or proxy-sent codes.Canceled. When
the latter occurs (e.g. an intermediary proxy resets the stream), the
retry loop silently terminates and the client never reconnects.
Switch to ctx.Err() in the signal Receive loop and management Sync/Job
handlers, and stop matching gRPC Canceled/DeadlineExceeded in the flow
client's isContextDone helper. With this change, a server-sent Canceled
is treated as a transient error and the backoff retry loop continues.
The Status recorder used to fire notifier callbacks while holding d.mux:
- notifyPeerListChanged / notifyPeerStateChangeListeners ran from inside
the locked section of every Update*/AddPeerStateRoute/etc.
- notifyAddressChanged ran from UpdateLocalPeerState and CleanLocalPeerState
while d.mux was held.
- onConnectionChanged was registered with a defer above defer d.mux.Unlock,
so it executed before the mutex was released in the Mark*Connected/
Disconnected helpers.
- notifyPeerStateChangeListeners did a blocking channel send under d.mux,
so a slow subscriber stalled every other d.mux holder.
A listener that re-enters the recorder (e.g. calls GetFullStatus from
within a callback) deadlocks against d.mux, and any callback that takes
longer than expected stalls every other state query for its duration.
Capture the values needed for notification under the lock, release d.mux,
then call the notifier. Build per-peer router-state snapshots inside the
lock and dispatch them via dispatchRouterPeers afterwards. The router-peer
channel send stays blocking, but now happens outside d.mux so a slow
consumer cannot stall any other d.mux holder, and no peer state
transitions are silently dropped.
The notifier itself is unchanged: its internal state was already protected
by its own locks, and the field d.notifier is set once in NewRecorder and
never reassigned, so reading it without d.mux is safe.
Also fix a pre-existing race in Test_notifier_RemoveListener /
Test_notifier_SetListener: setListener spawns a goroutine that writes
listener.peers, but the tests read listener.peers without waiting for it.
* [relay] evict foreign client cache on disconnect
When a foreign relay's TCP connection drops, the manager's
onServerDisconnected handler only triggered reconnect logic for the
home server; the disconnected foreign entry stayed in the relayClients
cache. Subsequent OpenConn calls reused the closed client until the
60-second cleanup tick evicted it, breaking peer connectivity through
that relay for up to a minute.
Evict the foreign entry from the cache on disconnect so the next
OpenConn dials a fresh client.
Also:
- Make the reconnect backoff cap configurable via WithMaxBackoffInterval
ManagerOption; the previous hard-coded 60s constant forced
TestAutoReconnect to sleep ~61s. Test now polls Ready() and finishes
in ~2s.
- Add NB_HOME_RELAY_SERVERS env var that overrides the relay URL list
received from management, so a peer can be pinned to a specific home
relay (used by the netbird-conn-lab Edge 4 reproducer).
* [client] treat empty NB_HOME_RELAY_SERVERS as unset
Returning (urls=[], ok=true) when the env var contained only separators or
whitespace caused callers to wipe the mgmt-provided relay list, leaving the
peer with no relays. Treat a parsed-empty result the same as an unset env.
The JOB stream is a separate channel from the SYNC stream. Server-side
EOF or other transient errors on the JOB stream do not indicate that
the management connection is unhealthy — the SYNC stream remains the
authoritative state signal.
Previously, a JOB stream EOF would call notifyDisconnected and the
client would emit OnConnecting to the UI. The backoff retry would
reconnect the JOB stream, but handleJobStream never calls notifyConnected
on success, so the UI was stuck on "Connecting" until the next SYNC
event or health check.
Keep notifyDisconnected for codes.PermissionDenied since IsLoginRequired
relies on managementError to detect expired auth.
peerShouldReceiveUpdate waited 500ms for the expected update message,
and every outer wrapper across the management/server test suite paired
it with a 1s goroutine-drain timeout. Both were too tight for slower
CI runners (MySQL, FreeBSD, loaded sqlite), producing intermittent
"Timed out waiting for update message" failures in tests like
TestDNSAccountPeersUpdate, TestPeerAccountPeersUpdate, and
TestNameServerAccountPeersUpdate.
Introduce peerUpdateTimeout (5s) next to the helper and use it both in
the helper and in every outer wrapper so the two timeouts stay in sync.
Only runs down on failure; passing tests return as soon as the channel
delivers, so there is no slowdown on green runs.
Bump the IsHealthy() context timeout from 1s to 5s for both the
management and signal gRPC clients to reduce false negatives on
slower or congested connections.
* [debug] fix port collision in TestUpload
TestUpload hardcoded :8080, so it failed deterministically when anything
was already on that port and collided across concurrent test runs.
Bind a :0 listener in the test to get a kernel-assigned free port, and
add Server.Serve so tests can hand the listener in without reaching
into unexported state.
* [debug] drop test-only Server.Serve, use SERVER_ADDRESS env
The previous commit added a Server.Serve method on the upload-server,
used only by TestUpload. That left production with an unused function.
Reserve an ephemeral loopback port in the test, release it, and pass
the address through SERVER_ADDRESS (which the server already reads).
A small wait helper ensures the server is accepting connections before
the upload runs, so the close/rebind gap does not cause a false failure.
The Receive goroutine could outlive the test and call t.Logf after
teardown, panicking with "Log in goroutine after ... has completed".
Register a cleanup that waits for the goroutine to exit; ordering is
LIFO so it runs after client.Close, which is what unblocks Receive.
The test writes 500 packets per family and asserted exact-count
delivery within a 5s window, even though its own comment says "Some
packet loss is acceptable for UDP". On FreeBSD/QEMU runners the writer
loops cannot always finish all 500 before the 5s deadline closes the
readers (we have seen 411/500 in CI).
The real assertion of this test is the routing check — IPv4 peer only
gets v4- packets, IPv6 peer only gets v6- packets — which remains
strict. Replace the exact-count assertions with a >=80% delivery
threshold so runner speed variance no longer causes false failures.
* [client] Suppress ICE signaling and periodic offers in force-relay mode
When NB_FORCE_RELAY is enabled, skip WorkerICE creation entirely,
suppress ICE credentials in offer/answer messages, disable the
periodic ICE candidate monitor, and fix isConnectedOnAllWay to
only check relay status so the guard stops sending unnecessary offers.
* [client] Dynamically suppress ICE based on remote peer's offer credentials
Track whether the remote peer includes ICE credentials in its
offers/answers. When remote stops sending ICE credentials, skip
ICE listener dispatch, suppress ICE credentials in responses, and
exclude ICE from the guard connectivity check. When remote resumes
sending ICE credentials, re-enable all ICE behavior.
* [client] Fix nil SessionID panic and force ICE teardown on relay-only transition
Fix nil pointer dereference in signalOfferAnswer when SessionID is nil
(relay-only offers). Close stale ICE agent immediately when remote peer
stops sending ICE credentials to avoid traffic black-hole during the
ICE disconnect timeout.
* [client] Add relay-only fallback check when ICE is unavailable
Ensure the relay connection is supported with the peer when ICE is disabled to prevent connectivity issues.
* [client] Add tri-state connection status to guard for smarter ICE retry (#5828)
* [client] Add tri-state connection status to guard for smarter ICE retry
Refactor isConnectedOnAllWay to return a ConnStatus enum (Connected,
Disconnected, PartiallyConnected) instead of a boolean. When relay is
up but ICE is not (PartiallyConnected), limit ICE offers to 3 retries
with exponential backoff then fall back to hourly attempts, reducing
unnecessary signaling traffic. Fully disconnected peers continue to
retry aggressively. External events (relay/ICE disconnect, signal/relay
reconnect) reset retry state to give ICE a fresh chance.
* [client] Clarify guard ICE retry state and trace log trigger
Split iceRetryState.attempt into shouldRetry (pure predicate) and
enterHourlyMode (explicit state transition) so the caller in
reconnectLoopWithRetry reads top-to-bottom. Restore the original
trace-log behavior in isConnectedOnAllWay so it only logs on full
disconnection, not on the new PartiallyConnected state.
* [client] Extract pure evalConnStatus and add unit tests
Split isConnectedOnAllWay into a thin method that snapshots state and
a pure evalConnStatus helper that takes a connStatusInputs struct, so
the tri-state decision logic can be exercised without constructing
full Worker or Handshaker objects. Add table-driven tests covering
force-relay, ICE-unavailable and fully-available code paths, plus
unit tests for iceRetryState budget/hourly transitions and reset.
* [client] Improve grammar in logs and refactor ICE credential checks
* fix(client): skip MAC address filter for network addresses on iOS
iOS does not expose hardware (MAC) addresses due to Apple's privacy
restrictions (since iOS 14), causing networkAddresses() to return an
empty list because all interfaces are filtered out by the HardwareAddr
check. Move networkAddresses() to platform-specific files so iOS can
skip this filter.
* [client] Fix flow client Receive retry loop not stopping after Close
Use backoff.Permanent for canceled gRPC errors so Receive returns
immediately instead of retrying until context deadline when the
connection is already closed. Add TestNewClient_PermanentClose to
verify the behavior.
The connectivity.Shutdown check was meaningless because when the connection is
shut down, c.realClient.Events(ctx, grpc.WaitForReady(true)) on the nex line
already fails with codes.Canceled — which is now handled as a permanent error.
The explicit state check was just duplicating what gRPC already reports
through its normal error path.
* [client] remove WaitForReady from stream open call
grpc.WaitForReady(true) parks the RPC call internally until the
connection reaches READY, only unblocking on ctx cancellation.
This means the external backoff.Retry loop in Receive() never gets
control back during a connection outage — it cannot tick, log, or
apply its retry intervals while WaitForReady is blocking.
Removing it restores fail-fast behaviour: Events() returns immediately
with codes.Unavailable when the connection is not ready, which is
exactly what the backoff loop expects. The backoff becomes the single
authority over retry timing and cadence, as originally intended.
* [client] Add connection recreation and improve flow client error handling
Store gRPC dial options on the client to enable connection recreation
on Internal errors (RST_STREAM/PROTOCOL_ERROR). Treat Unauthenticated,
PermissionDenied, and Unimplemented as permanent failures. Unify mutex
usage and add reconnection logging for better observability.
* [client] Remove Unauthenticated, PermissionDenied, and Unimplemented from permanent error handling
* [client] Fix error handling in Receive to properly re-establish stream and improve reconnection messaging
* Fix test
* [client] Add graceful shutdown handling and test for concurrent Close during Receive
Prevent reconnection attempts after client closure by tracking a `closed` flag. Use `backoff.Permanent` for errors caused by operations on a closed client. Add a test to ensure `Close` does not block when `Receive` is actively running.
* [client] Fix connection swap to properly close old gRPC connection
Close the old `gRPC.ClientConn` after successfully swapping to a new connection during reconnection.
* [client] Reset backoff
* [client] Ensure stream closure on error during initialization
* [client] Add test for handling server-side stream closure and reconnection
Introduce `TestReceive_ServerClosesStream` to verify the client's ability to recover and process acknowledgments after the server closes the stream. Enhance test server with a controlled stream closure mechanism.
* [client] Add protocol error simulation and enhance reconnection test
Introduce `connTrackListener` to simulate HTTP/2 RST_STREAM with PROTOCOL_ERROR for testing. Refactor and rename `TestReceive_ServerClosesStream` to `TestReceive_ProtocolErrorStreamReconnect` to verify client recovery on protocol errors.
* [client] Update Close error message in test for clarity
* [client] Fine-tune the tests
* [client] Adjust connection tracking in reconnection test
* [client] Wait for Events handler to exit in RST_STREAM reconnection test
Ensure the old `Events` handler exits fully before proceeding in the reconnection test to avoid dropped acknowledgments on a broken stream. Add a `handlerDone` channel to synchronize handler exits.
* [client] Prevent panic on nil connection during Close
* [client] Refactor connection handling to use explicit target tracking
Introduce `target` field to store the gRPC connection target directly, simplifying reconnections and ensuring consistent connection reuse logic.
* [client] Rename `isCancellation` to `isContextDone` and extend handling for `DeadlineExceeded`
Refactor error handling to include `DeadlineExceeded` scenarios alongside `Canceled`. Update related condition checks for consistency.
* [client] Add connection generation tracking to prevent stale reconnections
Introduce `connGen` to track connection generations and ensure that stale `recreateConnection` calls do not override newer connections. Update stream establishment and reconnection logic to incorporate generation validation.
* [client] Add backoff reset condition to prevent short-lived retry cycles
Refine backoff reset logic to ensure it only occurs for sufficiently long-lived stream connections, avoiding interference with `MaxElapsedTime`.
* [client] Introduce `minHealthyDuration` to refine backoff reset logic
Add `minHealthyDuration` constant to ensure stream retries only reset the backoff timer if the stream survives beyond a minimum duration. Prevents unhealthy, short-lived streams from interfering with `MaxElapsedTime`.
* [client] IPv6 friendly connection
parsedURL.Hostname() strips IPv6 brackets. For http://[::1]:443, this turns it into ::1:443, which is not a valid host:port target for gRPC. Additionally, fmt.Sprintf("%s:%s", hostname, port) produces a trailing colon when the URL has no explicit port—http://example.com becomes example.com:. Both cases break the initial dial and reconnect paths. Use parsedURL.Host directly instead.
* [client] Add `handlerStarted` channel to synchronize stream establishment in tests
Introduce `handlerStarted` channel in the test server to signal when the server-side handler begins, ensuring robust synchronization between client and server during stream establishment. Update relevant test cases to wait for this signal before proceeding.
* [client] Replace `receivedAcks` map with atomic counter and improve stream establishment sync in tests
Refactor acknowledgment tracking in tests to use an `atomic.Int32` counter instead of a map. Replace fixed sleep with robust synchronization by waiting on `handlerStarted` signal for stream establishment.
* [client] Extract `handleReceiveError` to simplify receive logic
Refactor error handling in `receive` to a dedicated `handleReceiveError` method. Streamlines the main logic and isolates error recovery, including backoff reset and connection recreation.
* [client] recreate gRPC ClientConn on every retry to prevent dual backoff
The flow client had two competing retry loops: our custom exponential
backoff and gRPC's internal subchannel reconnection. When establishStream
failed, the same ClientConn was reused, allowing gRPC's internal backoff
state to accumulate and control dial timing independently.
Changes:
- Consolidate error handling into handleRetryableError, which now
handles context cancellation, permanent errors, backoff reset,
and connection recreation in a single path
- Call recreateConnection on every retryable error so each retry
gets a fresh ClientConn with no internal backoff state
- Remove connGen tracking since Receive is sequential and protected
by a new receiving guard against concurrent calls
- Reduce RandomizationFactor from 1 to 0.5 to avoid near-zero
backoff intervals
extraInitialRoutes() was meant to preserve only the fake IP route
(240.0.0.0/8) across TUN rebuilds, but it re-injected any initial
route missing from the current set. When the management server
advertised exit node routes (0.0.0.0/0) that were later filtered
by the route selector, extraInitialRoutes() re-added them, causing
the Android VPN to capture all traffic with no peer to handle it.
Store the fake IP route explicitly and append only that in notify(),
removing the overly broad initial route diffing.
* [relay] Replace net.Conn with context-aware Conn interface for relay transports
Introduce a listener.Conn interface with context-based Read/Write methods,
replacing net.Conn throughout the relay server. This enables proper timeout
propagation (e.g. handshake timeout) without goroutine-based workarounds
and removes unused LocalAddr/SetDeadline methods from WS and QUIC conns.
* [relay] Refactor Peer context management to ensure proper cleanup
Integrate context creation (`context.WithCancel`) directly in `NewPeer` and remove redundant initialization in `Work`. Add `ctxCancel` calls to ensure context is properly canceled during `Close` operations.
Update the mgmProber interface to use HealthCheck() instead of the
now-unexported GetServerPublicKey(), aligning with the changes in the
management client API.
* Unexport GetServerPublicKey, add HealthCheck method
Internalize server key fetching into Login, Register,
GetDeviceAuthorizationFlow, and GetPKCEAuthorizationFlow methods,
removing the need for callers to fetch and pass the key separately.
Replace the exported GetServerPublicKey with a HealthCheck() error
method for connection validation, keeping IsHealthy() bool for
non-blocking background monitoring.
Fix test encryption to use correct key pairs (client public key as
remotePubKey instead of server private key).
* Refactor `doMgmLogin` to return only error, removing unused response
* [client] Use `net.JoinHostPort` for consistency in constructing host-port pairs
* [client] Fix handling of IPv6 addresses by trimming brackets in `net.JoinHostPort`
* [client] Add Expose support to embed library
Add ability to expose local services via the NetBird reverse proxy
from embedded client code.
Introduce ExposeSession with a blocking Wait method that keeps
the session alive until the context is cancelled.
Extract ProtocolType with ParseProtocolType into the expose package
and use it across CLI and embed layers.
* Fix TestNewRequest assertion to use ProtocolType instead of int
* Add documentation for Request and KeepAlive in expose manager
* Refactor ExposeSession to pass context explicitly in Wait method
* Refactor ExposeSession Wait method to explicitly pass context
* Update client/embed/expose.go

* Add client metrics
* Add client metrics system with OpenTelemetry and VictoriaMetrics support
Implements a comprehensive client metrics system to track peer connection
stages and performance. The system supports multiple backend implementations
(OpenTelemetry, VictoriaMetrics, and no-op) and tracks detailed connection
stage durations from creation through WireGuard handshake.
Key changes:
- Add metrics package with pluggable backend implementations
- Implement OpenTelemetry metrics backend
- Implement VictoriaMetrics metrics backend
- Add no-op metrics implementation for disabled state
- Track connection stages: creation, semaphore, signaling, connection ready, and WireGuard handshake
- Move WireGuard watcher functionality to conn.go
- Refactor engine to integrate metrics tracking
- Add metrics export endpoint in debug server
* Add signaling metrics tracking for initial and reconnection attempts
* Reset connection stage timestamps during reconnections to exclude unnecessary metrics tracking
* Delete otel lib from client
* Update unit tests
* Invoke callback on handshake success in WireGuard watcher
* Add Netbird version tracking to client metrics
Integrate Netbird version into VictoriaMetrics backend and metrics labels. Update `ClientMetrics` constructor and metric name formatting to include version information.
* Add sync duration tracking to client metrics
Introduce `RecordSyncDuration` for measuring sync message processing time. Update all metrics implementations (VictoriaMetrics, no-op) to support the new method. Refactor `ClientMetrics` to use `AgentInfo` for static agent data.
* Remove no-op metrics implementation and simplify ClientMetrics constructor
Eliminate unused `noopMetrics` and refactor `ClientMetrics` to always use the VictoriaMetrics implementation. Update associated logic to reflect these changes.
* Add total duration tracking for connection attempts
Calculate total duration for both initial connections and reconnections, accounting for different timestamp scenarios. Update `Export` method to include Prometheus HELP comments.
* Add metrics push support to VictoriaMetrics integration
* [client] anchor connection metrics to first signal received
* Remove creation_to_semaphore connection stage metric
The semaphore queuing stage (Created → SemaphoreAcquired) is no longer
tracked. Connection metrics now start from SignalingReceived. Updated
docs and Grafana dashboard accordingly.
* [client] Add remote push config for metrics with version-based eligibility
Introduce remoteconfig.Manager that fetches a remote JSON config to control
metrics push interval and restrict pushing to a specific agent version
range. When NB_METRICS_INTERVAL is set, remote config is bypassed
entirely for local override.
* [client] Add WASM-compatible NewClientMetrics implementation
Replace NewClientMetrics in metrics.go with a WASM-specific stub in metrics_js.go, returning nil for compatibility with JS builds. Simplify method usage for WASM targets.
* Add missing file
* Update default case in DeploymentType.String to return "unknown" instead of "selfhosted"
* [client] Rework metrics to use timestamped samples instead of histograms
Replace cumulative Prometheus histograms with timestamped point-in-time
samples that are pushed once and cleared. This fixes metrics for sparse
events (connections/syncs that happen once at startup) where rate() and
increase() produced incorrect or empty results.
Changes:
- Switch from VictoriaMetrics histogram library to raw Prometheus text
format with explicit millisecond timestamps
- Reset samples after successful push (no resending stale data)
- Rename connection_to_handshake → connection_to_wg_handshake
- Add netbird_peer_connection_count metric for ICE vs Relay tracking
- Simplify dashboard: point-based scatter plots, donut pie chart
- Add maxStalenessInterval=1m to VictoriaMetrics to prevent forward-fill
- Fix deployment_type Unknown returning "selfhosted" instead of "unknown"
- Fix inverted shouldPush condition in push.go
* [client] Add InfluxDB metrics backend alongside VictoriaMetrics
Add influxdb.go with timestamped line protocol export for sparse
one-shot events. Restore victoria.go to use proper Prometheus
histograms. Update Grafana dashboards, add InfluxDB datasource,
and update docs.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* [client] Fix metrics issues and update dev docker setup
- Fix StopPush not clearing push state, preventing restart
- Fix race condition reading currentConnPriority without lock in recordConnectionMetrics
- Fix stale comment referencing old metrics server URL
- Update docker-compose for InfluxDB: add scoped tokens, .env config, init scripts
- Rename docker-compose.victoria.yml to docker-compose.yml
* [client] Add anonymised peer tracking to pushed metrics
Introduce peer_id and connection_pair_id tags to InfluxDB metrics.
Public keys are hashed (truncated SHA-256) for anonymisation. The
connection pair ID is deterministic regardless of which side computes
it, enabling deduplication of reconnections in the ICE vs Relay
dashboard. Also pin Grafana to v11.6.0 for file-based provisioning
and fix datasource UID references.

Auto-update logic moved out of the UI into a dedicated updatemanager.Manager service that runs in the connection layer. The
UI no longer polls or checks for updates independently.
The update manager supports three modes driven by the management server's auto-update policy:
No policy set by mgm: checks GitHub for the latest version and notifies the user (previous behavior, now centralized)
mgm enforces update: the "About" menu triggers installation directly instead of just downloading the file — user still initiates the action
mgm forces update: installation proceeds automatically without user interaction
updateManager lifecycle is now owned by daemon, giving the daemon server direct control via a new TriggerUpdate RPC
Introduces EngineServices struct to group external service dependencies passed to NewEngine, reducing its argument count from 11 to 4
* Fix DNS probe thread safety and avoid blocking engine sync
Refactor ProbeAvailability to prevent blocking the engine's sync mutex
during slow DNS probes. The probe now derives its context from the
server's own context (s.ctx) instead of accepting one from the caller,
and uses a mutex to ensure only one probe runs at a time — new calls
cancel the previous probe before starting. Also fixes a data race in
Stop() when accessing probeCancel without the probe mutex.
* Ensure DNS probe thread safety by locking critical sections
Add proper locking to prevent data races when accessing shared resources during DNS probe execution and Stop(). Update handlers snapshot logic to avoid conflicts with concurrent writers.
* Rename context and remove redundant cancellation
* Cancel first and lock
* Add locking to ensure thread safety when reactivating upstream servers
Capture engine reference before actCancel() in cleanupConnection().
After actCancel(), the connectWithRetryRuns goroutine sets engine to nil,
causing connectClient.Stop() to skip shutdown. This allows the goroutine
to set ErrResetConnection on the shared state after Down() clears it,
causing the next Up() to fail.
Wrap peerStateUpdate send in a nested select to prevent goroutine
blocking when the consumer has exited, which could fill the
subscription buffer and deadlock the Status mutex.
Up() acquired s.mutex with a deferred unlock, then called waitForUp()
while still holding the lock. waitForUp() blocks for up to 50 seconds
waiting on clientRunningChan/clientGiveUpChan, starving all concurrent
gRPC calls that require the same mutex (Status, ListProfiles, etc.).
Replace the deferred unlock with explicit s.mutex.Unlock() on every
early-return path and immediately before waitForUp(), matching the
pattern already used by the clientRunning==true branch.
In netstack (proxy) mode, the process lacks permission to create
/var/run/wireguard, making the UAPI listener unnecessary and causing
a misleading error log. Introduce NewUSPConfigurerNoUAPI and use it
for the netstack device to avoid attempting to open the UAPI socket
entirely. Also consolidate UAPI error logging to a single call site.
could interleave with a sleep/wake event causing out-of-order state
transitions. The mutex now covers the full duration of each handler
including the status check, the Up/Down call, and the flag update.
Note: if Up or Down commands are triggered in parallel with sleep/wake
events, the overall ordering of up/down/sleep/wake operations is still
not guaranteed beyond what the mutex provides within the handler itself.
* [Client] Remove connection semaphore
Remove the semaphore and the initial random sleep time (300ms) from the connectivity logic to speed up the initial connection time.
Note: Implement limiter logic that can prioritize router peers and keep the fast connection option for the first few peers.
* Remove unused function
* [client] fix busy-loop in network monitor routing socket on macOS/BSD
After system wakeup, the AF_ROUTE socket created by Go's unix.Socket()
is non-blocking, causing unix.Read to return EAGAIN immediately and spin
at 100% CPU filling the log with thousands of warnings per second.
Replace the tight read loop with a unix.Select call that blocks until
the fd is readable, checking ctx cancellation on each 1-second timeout.
Fatal errors (EBADF, EINVAL) now return an error instead of looping.
* [client] add fd range validation in waitReadable to prevent out-of-bound errors
* Ensure route settlement on iOS before handling DNS responses to prevent bypassing the tunnel.
* add more logs
* rollback debug changes
* rollback changes
* [client] Improve logging and add comments for iOS route settlement logic
- Switch iOS route settlement log level from Debug to Trace for finer control.
- Add clarifying comments for `waitForRouteSettlement` on non-iOS platforms.

* Refactor WG endpoint setup with role-based proxy activation
For relay connections, the controller (initiator) now activates the
wgProxy before configuring the WG endpoint, while the non-controller
(responder) configures the endpoint first with a delayed update, then
activates the proxy after. This prevents the responder from sending
traffic through the proxy before WireGuard is ready to receive it,
avoiding handshake congestion when both sides try to initiate
simultaneously.
For ICE connections, pass hasRelayBackup as the setEndpointNow flag
so the responder sets the endpoint immediately when a relay fallback
exists (avoiding the delayed update path since relay is already
available as backup).
On ICE disconnect with relay fallback, remove the duplicate
wgProxyRelay.Work() calls — the relay proxy is already active from
initial setup, so re-activating it is unnecessary.
In EndpointUpdater, split ConfigureWGEndpoint into explicit
configureAsInitiator and configureAsResponder paths, and add the
setEndpointNow parameter to let the caller control whether the
responder applies the endpoint immediately or defers it. Add unused
SwitchWGEndpoint and RemoveEndpointAddress methods. Remove the
wgConfigWorkaround sleep from the relay setup path.
* Fix redundant wgProxyRelay.Work() call during relay fallback setup
* Simplify WireGuard endpoint configuration by removing unused parameters and redundant logic
* Fix WebSocket support by implementing Hijacker interface
Add responsewriter.PassthroughWriter to preserve optional HTTP interfaces
(Hijacker, Flusher, Pusher) when wrapping http.ResponseWriter in middleware.
Without this delegation:
- WebSocket connections fail (can't hijack the connection)
- Streaming breaks (can't flush buffers)
- HTTP/2 push doesn't work
* Add HijackTracker to manage hijacked connections during graceful shutdown
* Refactor HijackTracker to use middleware for tracking hijacked connections
* Refactor server handler chain setup for improved readability and maintainability
When an ICE connection disconnects and falls back to relay, reset the
WireGuard endpoint and handshake watcher if the remote peer's ICE session
has changed. This ensures the controller re-establishes a fresh WireGuard
handshake rather than waiting on a stale endpoint from the previous session.
* Optimize Windows DNS performance with domain batching and batch mode
Implement two-layer optimization to reduce Windows NRPT registry operations:
1. Domain Batching (host_windows.go):
- Batch domains per NRPT
- Reduces NRPT rules by ~97% (e.g., 184 domains: 184 rules → 4 rules)
- Modified addDNSMatchPolicy() to create batched NRPT entries
- Added comprehensive tests in host_windows_test.go
2. Batch Mode (server.go):
- Added BeginBatch/EndBatch methods to defer DNS updates
- Modified RegisterHandler/DeregisterHandler to skip applyHostConfig in batch mode
- Protected all applyHostConfig() calls with batch mode checks
- Updated route manager to wrap route operations with batch calls
* Update tests
* Fix log line
* Fix NRPT rule index to ensure cleanup covers partially created rules
* Ensure NRPT entry count updates even on errors to improve cleanup reliability
* Switch DNS batch mode logging from Info to Debug level
* Fix batch mode to not suppress critical DNS config updates
Batch mode should only defer applyHostConfig() for RegisterHandler/
DeregisterHandler operations. Management updates and upstream nameserver
failures (deactivate/reactivate callbacks) need immediate DNS config
updates regardless of batch mode to ensure timely failover.
Without this fix, if a nameserver goes down during a route update,
the system DNS config won't be updated until EndBatch(), potentially
delaying failover by several seconds.
Or if you prefer a shorter version:
Fix batch mode to allow immediate DNS updates for critical paths
Batch mode now only affects RegisterHandler/DeregisterHandler.
Management updates and nameserver failures always trigger immediate
DNS config updates to ensure timely failover.
* Add DNS batch cancellation to rollback partial changes on errors
Introduces CancelBatch() method to the DNS server interface to handle error
scenarios during batch operations. When route updates fail partway through, the DNS
server can now discard accumulated changes instead of applying partial state. This
prevents leaving the DNS configuration in an inconsistent state when route manager
operations encounter errors.
The changes add error-aware batch handling to prevent partial DNS configuration
updates when route operations fail, which improves system reliability.
* Fix race condition and ensure correct message ordering in
connection establishment
Reorder operations in OpenConn to register the connection before
waiting for peer availability. This ensures:
- Connection is ready to receive messages before peer subscription
completes
- Transport messages and onconnected events maintain proper ordering
- No messages are lost during the connection establishment window
- Concurrent OpenConn calls cannot create duplicate connections
If peer availability check fails, the pre-registered connection is
properly cleaned up.
* Handle service shutdown during relay connection initialization
Ensure relay connections are properly cleaned up when the service is not running by verifying `serviceIsRunning` and removing stale entries from `c.conns` to prevent unintended behaviors.
* Refactor relay client Conn/connContainer ownership and decouple Conn from Client
Conn previously held a direct *Client pointer and called client methods
(writeTo, closeConn, LocalAddr) directly, creating a tight bidirectional
coupling. The message channel was also created externally in OpenConn and
shared between Conn and connContainer with unclear ownership.
Now connContainer fully owns the lifecycle of both the channel and the
Conn it wraps:
- connContainer creates the channel (sized by connChannelSize const)
and the Conn internally via newConnContainer
- connContainer feeds messages into the channel (writeMsg), closes and
drains it on shutdown (close)
- Conn reads from the channel (Read) but never closes it
Conn is decoupled from *Client by replacing the *Client field with
three function closures (writeFn, closeFn, localAddrFn) that are wired
by newConnContainer at construction time. Write, Close, and LocalAddr
delegate to these closures. This removes the direct dependency while
keeping the identity-check logic: writeTo and closeConn now compare
connContainer pointers instead of Conn pointers to verify the caller
is the current active connection for that peer.
* Fix race condition and ensure correct message ordering in
connection establishment
Reorder operations in OpenConn to register the connection before
waiting for peer availability. This ensures:
- Connection is ready to receive messages before peer subscription
completes
- Transport messages and onconnected events maintain proper ordering
- No messages are lost during the connection establishment window
- Concurrent OpenConn calls cannot create duplicate connections
If peer availability check fails, the pre-registered connection is
properly cleaned up.
* Handle service shutdown during relay connection initialization
Ensure relay connections are properly cleaned up when the service is not running by verifying `serviceIsRunning` and removing stale entries from `c.conns` to prevent unintended behaviors.
* Add gRPC update debouncing mechanism
Implements backpressure handling for peer network map updates to
efficiently handle rapid changes. First update is sent immediately,
subsequent rapid updates are coalesced, ensuring only the latest
update is sent after a 1-second quiet period.
* Enhance unit test to verify peer count synchronization with debouncing and timeout handling
* Debounce based on type
* Refactor test to validate timer restart after pending update dispatch
* Simplify timer reset for Go 1.23+ automatic channel draining
Remove manual channel drain in resetTimer() since Go 1.23+ automatically
drains the timer channel when Stop() returns false, making the
select-case pattern unnecessary.
Add defensive nil checks in ThreadSafeAgent.Close() to prevent panic
when agent field is nil. This can occur during Windows suspend/resume
when network interfaces are disrupted or the pion/ice library returns
nil without error.
Also capture agent pointer in local variable before goroutine execution
to prevent race conditions.
Fixes service crashes on laptop wake-up.
Avoid repeated conversions during route setup. The toInterface helper ensures
the conversion happens only once regardless of how many routes are added
or removed.
Start the WireGuard watcher before configuring the WG endpoint to ensure it captures the initial handshake timestamp.
Previously, the watcher was started after endpoint configuration, causing it to miss the handshake that occurred during setup.
When a deleted peer tries to reconnect, GetUserIDByPeerKey was returning
Internal error instead of NotFound, causing clients to retry indefinitely
instead of recognizing the unrecoverable PermissionDenied error.
This fix:
1. Updates GetUserIDByPeerKey to properly return NotFound when peer doesn't exist
2. Updates Sync handler to convert NotFound to PermissionDenied with message
'peer is not registered', matching the behavior of GetAccountIDForPeerKey
Fixes the regression introduced in v0.61.1 where deleted peers would see:
- Before: 'rpc error: code = Internal desc = failed handling request' (retry loop)
- After: 'rpc error: code = PermissionDenied desc = peer is not registered' (exits)
* Add IPv6 support to UDP WireGuard proxy
Add IPv6 packet header support in UDP raw socket proxy
to handle both IPv4 and IPv6 source addresses.
Refactor error handling in proxy bind implementations
to validate endpoints before acquiring locks.
* Consolidate authentication logic
- Moving auth functions from client/internal to client/internal/auth package
- Creating unified auth.Auth client with NewAuth() constructor
- Replacing direct auth function calls with auth client methods
- Refactoring device flow and PKCE flow implementations
- Updating iOS/Android/server code to use new auth client API
* Refactor PKCE auth and login methods
- Remove unnecessary internal package reference in PKCE flow test
- Adjust context assignment placement in iOS and Android login methods
When Down() and Up() are called in quick succession, the connectWithRetryRuns goroutine could set ErrResetConnection after Down() had cleared the state, causing the subsequent Up() to fail.
Fix by waiting for the goroutine to exit (via clientGiveUpChan) before Down() returns. Uses a 5-second timeout to prevent RPC timeouts while ensuring the goroutine completes in most cases.
- Remove WaitGroup, make SemaphoreGroup a pure semaphore
- Make Add() return error instead of silently failing on context cancel
- Remove context parameter from Done() to prevent slot leaks
- Fix missing Done() call in conn.go error path
The UI can get stuck showing "Connecting" status even after the daemon successfully connects and reports "Connected" status. This occurs because the condition to update the UI to "Connected" state checks the wrong flag.
Expose the profile-manager service for Android. Logout was not part of the manager service implementation. In the future, I recommend moving this logic there.
