DisableAutoConnect semantics
============================
Scope: governs ONLY the service-Start auto-connect decision. Once the
connection goroutine has been spawned (by any path), the flag is never
consulted again — the retry loop keeps trying to connect until ctx is
cancelled by Down / Stop / Logout.
Cases
-----
1. Service Start + DisableAutoConnect = true
- No connection goroutine spawned.
- clientRunning stays false.
- State set to StatusIdle.
- Daemon stays passive until an explicit Up RPC.
2. Service Start + DisableAutoConnect = false
- Spawn connectWithRetryRuns.
- clientRunning = true.
- Retry loop runs until ctx cancelled.
3. Up RPC (any value of DisableAutoConnect)
- Flag ignored. The user / admin explicitly asked to connect — by
definition not "auto".
- Spawn connectWithRetryRuns.
- clientRunning = true.
4. MDM-triggered restart (any value of DisableAutoConnect)
- Flag ignored. An MDM policy change applies new config to an
already-running engine; treated as an implicit Up.
- Spawn connectWithRetryRuns.
- clientRunning = true.
5. Down / Stop / Logout
- Cancels ctx → connectWithRetryRuns exits → close(giveUpChan).
- cleanupConnection clears clientRunning = false.
- DisableAutoConnect not involved.

UI sends full config snapshot with all values. It doesn't
make sense to block it if the values are aligned with the
values constrained by the MDM policy. It's just simplier
to allow values that are compliant. (this goes for the CLI
as well at this point)

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 (?)

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.
* Moves test helper at te very bottom
* Addresses github comments
* No lock no copy
* Prevents engine not stopping within 10 secs from being paired by another instance
We instead juts SKIP updating the policy, so
1. the MDM ticker will kick in 1 minute time,
2. find the policy misaligned,
3. enter the onMDMPolicyChange,
4. find the s.clientRunning == true
(because it is set to false only in server cleanupConnection,
and not by s.actCancel())
5. call s.actCancel() again if not nil
6. immediately return from <-s.clientGiveUpChan
7. finally call s.restartEngineForMDMLocked()
* Since we ARE running there should be a config
If the config was cancelled midflight, connect will abort later on
* DisableAutoConnect should not stop a running connection.
DisableAutoConnect should just avoid the connection attempts *when the service starts*.
If we are started and we are up and running, DisableAutoConnect should not kick in.

* Adds list of MDM managed fields in the debug bundle
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
* [client] Fix exit node menu not refreshing on Windows
TrayOpenedCh is not implemented in the systray library on Windows,
so exit nodes were never refreshed after the initial connect. Combined
with the management sync not having populated routes yet when the
Connected status fires, this caused the exit node menu to remain empty
permanently after disconnect/reconnect cycles.
Add a background poller on Windows that refreshes exit nodes while
connected, with fast initial polling to catch routes from management
sync followed by a steady 10s interval. On macOS/Linux, TrayOpenedCh
continues to handle refreshes on each tray open.
Also fix a data race on connectClient assignment in the server's connect()
method and add nil checks in CleanState/DeleteState to prevent panics
when connectClient is nil.
* Remove unused exitNodeIDs
* Remove unused exitNodeState struct
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.
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.
CLI: new expose command to publish a local port with flags for PIN, password, user groups, custom domain, name prefix and protocol (HTTP default).
Management/API: create/renew/stop expose sessions (streamed status), automatic naming/domain, TTL renewals, background expiration, new management RPCs and client methods.
UI/API: account settings now include peer_expose_enabled and peer_expose_groups; new activity codes for peer expose events.
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.
* 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.
- Connect on daemon start only if the file existed before
- fixed a bug that happened when the default profile config was removed, which would recreate it and reset the active profile to the default.
* Fix engine shutdown deadlock and message handling races
- Release syncMsgMux before waiting for shutdownWg to prevent deadlock
- Check context inside lock in handleSync and receiveSignalEvents
- Prevents nil pointer access when messages arrive during engine stop
Adds a new NotifyOSLifecycle RPC and server handler to centralize OS sleep/wake handling, introduces Server.sleepTriggeredDown for coordination, updates client UI to call the new RPC, and adjusts the internal sleep event enum zero-value semantics.
The status cmd will not be blocked by the ICE probe
Refactor the TURN and STUN probe, and cache the results. The NetBird status command will indicate a "checking…" state.
This PR improves the NetBird client's status checking mechanism by implementing earlier detection of client state changes and better handling of connection lifecycle management. The key improvements focus on:
• Enhanced status detection - Added waitForReady option to StatusRequest for improved client status handling
• Better connection management - Improved context handling for signal and management gRPC connections• Reduced connection timeouts - Increased gRPC dial timeout from 3 to 10 seconds for better reliability
• Cleaner error handling - Enhanced error propagation and context cancellation in retry loops
Key Changes
Core Status Improvements:
- Added waitForReady optional field to StatusRequest proto (daemon.proto:190)
- Enhanced status checking logic to detect client state changes earlier in the connection process
- Improved handling of client permanent exit scenarios from retry loops
Connection & Context Management:
- Fixed context cancellation in management and signal client retry mechanisms
- Added proper context propagation for Login operations
- Enhanced gRPC connection handling with better timeout management
Error Handling & Cleanup:
- Moved feedback channels to upper layers for better separation of concerns
- Improved error handling patterns throughout the client server implementation
- Fixed synchronization issues and removed debug logging
The client status is not enough to protect the RPC calls from concurrency issues, because it is handled internally in the client in an asynchronous way.
