* [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.

* [management] Fetch complete user data in ValidateTunnelPeer
Previously the `ValidateTunnelPeer` method used by the ProxyService
would fetch user information from the database if the connected peer
was associated with a user ID, but it would not consult the IdP data
for cached info from JWT claims like email. This caused the value of
the injected `X-Netbird-User` header to always display the peer ID and
never the user email associated with the peer as expected.
This change adds an optional IdP manager to the ProxyService and
fetches the complete user data from it if present.
* [management] Refactor ValidateTunnelPeer principal info gathering
This refactors the gathering of info on proxy tunnel peer principals

* [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.
When JWT group sync is enabled with a restrictive JWTAllowGroups list, the local owner of an embedded-IdP (Dex) deployment can get locked out. The allow-groups check runs account-wide but local password users do not receive
external IdP group claims, so they can't satisfy the allowed list.
This skips JWT group evaluation for local Dex users so the restriction and JWT group sync continue to apply to external-IdP users as intended.

This commit tries to settle things with an old PR-4237 which had relaxed
the case where the SetConfig returned an `Unavailable` code error.
Under this circumnstance the PR allowed the upFunc to just emit a warning and
progress further with the login gRPC. Since the login call is consuming
the --management-url coming from the `up` command, it might be possible
to abuse the "Unavailable" code to inject a management URL that is different
from the configured one even though the --disable-update-settings is set
to true (?)

* Avoid locking on clientRunning bool when the connection is aborted for whatever reason
We want to just signal this through the giveUpChan, we will manage the signal from
the waiter side and in case set it to false there. THis way we avoid locking,
which should allow the MDM down+wait_for_term_chan_signal_+up procedure
clientRunning is used to signal two different conditions here:
1. the initialization procedure is over (we have an engine)
2. the connection being up (or being attempted)
Probably these two functionalities should not alias, and the failure of the second condition
(because of any error) should just drive a reconnection (currently it's not happening,
and we silently go idle).
OR, mor probably, the two things are the SAME and there should not exist a case where
we did the "Up" initialization and connection attempt but we are not still attempting it.

* [client] Index peer tunnel IPs for O(1) PeerStateByIP lookup
Replace the linear scan over all peers with an ipToKey map maintained
by AddPeer/RemovePeer, covering both IPv4 and IPv6 tunnel addresses.
Offline peers are intentionally no longer resolvable by IP: only active
peers can carry traffic, so IdentityForIP and the DNS disconnected-peer
filter now treat them as unknown, same as foreign IPs.
Skip the DNS answer filter for single-record responses; dropping the
only answer was always restored by the empty-answer escape hatch, so
the fast path is behavior-neutral.
* Ensure `ipToKey` entries are only removed if they match the peer being deleted, preventing accidental removal of unrelated mappings.
