* [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.
- Add GetSelectedClientRoutes() to the route manager that filters through FilterSelectedExitNodes, returning only active routes instead of all management routes
- Use GetSelectedClientRoutes() in the DNS route checker so deselected exit nodes' 0.0.0.0/0 no longer matches upstream DNS IPs — this prevented the resolver from switching
away from the utun-bound socket after exit node deselection
- Initialize iOS DNS server with host DNS fallback addresses (1.1.1.1:53, 1.0.0.1:53) and a permanent root zone handler, matching Android's behavior — without this, unmatched
DNS queries arriving via the 0.0.0.0/0 tunnel route had no handler and were silently dropped
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
