* [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.
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.
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.
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.
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
- DNS resolution broke after deselecting an exit node because the route checker used all client routes (including deselected ones) to decide how to forward upstream DNS
queries
- Added GetSelectedClientRoutes() to the route manager that filters out deselected exit nodes, and switched the DNS route checker to use it
- Confirmed fix via device testing: after deselecting exit node, DNS queries now correctly use a regular network socket instead of binding to the utun interface
* [client] Support embed.Client on Android with netstack mode
embed.Client.Start() calls ConnectClient.Run() which passes an empty
MobileDependency{}. On Android, the engine dereferences nil fields
(IFaceDiscover, NetworkChangeListener, DnsReadyListener) causing panics.
Provide complete no-op stubs so the engine's existing Android code
paths work unchanged — zero modifications to engine.go:
- Add androidRunOverride hook in Run() for Android-specific dispatch
- Add runOnAndroidEmbed() with complete MobileDependency (all stubs)
- Wire default stubs via init() in connect_android_default.go:
noopIFaceDiscover, noopNetworkChangeListener, noopDnsReadyListener
- Forward logPath to c.run()
Tested: embed.Client starts on Android arm64, joins mesh via relay,
discovers peers, localhost proxy works for TCP+UDP forwarding.
* [client] Fix TestServiceParamsPath for Windows path separators
Use filepath.Join in test assertions instead of hardcoded POSIX paths
so the test passes on Windows where filepath.Join uses backslashes.
* [client] Use `net.JoinHostPort` for consistency in constructing host-port pairs
* [client] Fix handling of IPv6 addresses by trimming brackets in `net.JoinHostPort`
Remove client secret from gRPC auth flow. The secret was originally included to support providers like Google Workspace that don't offer a proper PKCE flow, but this is no longer necessary with the embedded IdP. Deployments using such providers should migrate to the embedded IdP instead.
* Simplify Android ConnStatus API with integer constants
Replace dual field PeerInfo design with unified integer based
ConnStatus field and exported gomobile friendly constants.
Changes:
> PeerInfo.ConnStatus: changed from string to int
> Export three constants: ConnStatusIdle, ConnStatusConnecting,ConnStatusConnected (mapped to peer.ConnStatus enum values)
> Updated PeersList() to convert peer enum directly to int
Benefits:
> Simpler API surface with single ConnStatus field
> Better gomobile compatibility for cross-platform usage
> Type-safe integer constants across language boundaries
* test: add All group to setupTestAccount fixture
The setupTestAccount() test helper was missing the required "All" group,
causing "failed to get group all: no group ALL found" errors during
test execution. Add the All group with all test peers to match the
expected account structure.
Fixes the failing account and types package tests when GetGroupAll()
is called in test scenarios.
* [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

* client/ui: fix Exit Node submenu separator accumulation on Windows
On Windows the tray uses a background poller (every 10s) instead of
TrayOpenedCh to keep the Exit Node menu fresh. Each poll that has a
selected exit node called s.mExitNode.AddSeparator() before the
"Deselect All" item. Because AddSeparator() returns no handle the
separator was never removed in the cleanup pass of
recreateExitNodeMenu(), while every other item (exit node checkboxes
and the "Deselect All" entry) was properly tracked and removed.
After the client has been running for a while with an exit node
selected this leaves hundreds of separator lines stacked in the
submenu, filling the screen height with blank entries (#4702).
On Linux/FreeBSD this is masked because the parent mExitNode item
itself is removed and recreated each cycle, wiping all children
including orphaned separators.
Fix: replace the untracked AddSeparator() call with a regular disabled
sub-menu item that is stored in mExitNodeSeparator and removed at the
start of each recreateExitNodeMenu() call alongside mExitNodeDeselectAll.
Fixes#4702
* client/ui: extract addExitNodeDeselectAll to reduce cognitive complexity
Move the separator + deselect-all creation and its goroutine listener
out of recreateExitNodeMenu into a dedicated helper, bringing the
function's cognitive complexity back under the SonarCloud threshold.
The internal Target model uses a plain bool for ProxyProtocol,
which was always serialized to the API response as false even
when not configured. Only set the API field when true so it
gets omitted via omitempty when unset.
