New() builds s.connecClient and is called when the gRPC service is started.
Up() is invoked only IF a gRPC service IS running which is possible only if the New() was
called.
Needed to avoid this workaround

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.
Prepare for next step
Collapse error log into s.connect and rename it to more explicit connectOnce

* UI behavior conflicts relaxation
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)

* Fixup presharedkey
* Apply MDM locks
* Toggle gray in/out for Advanced Settings
* Adds support for disabling of Profiles and UpdateSettings feature flags
* Adds Gate Login as well when --disable-update-settings=true is given to service
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 (?)
* Evaluate disable-update-settings errors only when there's an actual override
* [UI] Fixup advanced Settings
* [UI] Fixup for preshared key
* [UI] Fixup for profile enable/disable toggle

Then we receive MDM and transition the cache bool value to the actual
MDM imposed state

* 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.
* 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.
Another PR will follow about this topic
* Removes unused vars
* Moves callback into Run method arg
* align comment to removal of DisableAutoConnect
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
* Removes unused managed_fields data.
This was initially used to drive the UI but approach changed
to reload config/features upon notifications which makes this data redundant.
* Reorder stuff
* Unexport unrequired vars/functions
PoliciesEqual → policiesEqual
AllKeys → allKeys
* Adds list of MDM managed fields in the debug bundle
* [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.
- Engine.Start takes syncMsgMux with a deferred unlock (engine.go:445) and parks in receiveSignalEvents → WaitStreamConnected (engine.go:1762), which only wakes on
signal-stream connect or client-context cancellation.
- When signal never connects, the 30s startup timeout fires and embed.Client.Start's rollback (embed.go:281) called client.Stop() → Engine.Stop, which blocks acquiring
syncMsgMux (engine.go:318). The cancel() that would unpark Start was deferred until Start returned — permanent cycle. RemovePeer calls (g43/g385) then queue behind the
lifecycle mutex.
- Notably, embed.Client.Stop and the daemon's cleanupConnection both cancel before stopping — the startup rollback was the only path that didn't.

* [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.
* Adds heuristic to detect an edge case on Linux where a system has configured logrotate as a separate service to rotate log files which would mangle our client log files. If we detect logrotate being configured for netbird, we disable our rotation.
* Adds new env var to disable log rotation: NB_LOG_DISABLE_ROTATION
* Adds compressed and plain logrotate files to debug bundle.
* Replaces lumberjack with timberjack (maintained fork with bug fixes and extra features).
* Clarifies which daemon version is running in the bundle stats.
* Change logging for client service status to console
* 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.
* Refactor to use a common checker for development version
* Adds commit sha to development version for cobra command only
Leave dashboard unaffected
* Adjust for "v0.31.1-dev" test case
which must be considered pre-release
* Drop synthetic "dev"/"0.50.0-dev" firewall feature-gate fixtures
These test cases encoded the loose strings.Contains(v, "dev")
semantics inherited from peerSupportedFirewallFeatures, but
NetbirdVersion() never produces those values — only the literal
"development" (and now "development-<sha>[-dirty]") ever flows
through the wire. The agent owns the semantics of an ephemeral
development build, so the tests should exercise the strings we
actually emit.
Replaced with development, development-<sha> and
development-<sha>-dirty cases that match the HasPrefix("development")
predicate introduced upstream.
* Remove unexistent tests on wire format
The sha / dirty flag are added only when the CLI asks the version.
Account versions is unaffacted and can only strictly match "development"
* Adds tests for IsDevelopmentVersion
* fix(proxy): gate tunnel-peer fast-path on inbound listener marker
forwardWithTunnelPeer previously accepted any RFC1918 / ULA / CGNAT
source IP, so a public client whose address happened to fall in those
ranges could bypass the configured operator auth scheme by colliding
with a known tunnel IP. The fast-path is now gated on
TunnelLookupFromContext(r.Context()) being present — that context value
is attached only by the per-account inbound (overlay) listener, so the
host-facing listener never enters this branch.
Tests updated to reflect the new requirement: requests that don't
carry the inbound marker now fall through to the regular auth flow.
* fix(proxy): harden inbound listener resource + startup-ctx handling
Three correctness fixes on the per-account inbound path, with tests:
- Close the logrus ErrorLog PipeWriter on tearDown. WriterLevel hands
back an *io.PipeWriter backed by a pipe + scanner goroutine that the
caller owns; the two writers per account (https + plain) were never
closed, leaking the pipe and goroutine on every teardown.
- Run the post-Start hooks on context.Background(). runClientStartup
is launched in a goroutine from AddPeer and was inheriting the
caller's request-scoped ctx, so a cancelled request could abort the
inbound bring-up or fail the management status notification. The
tail is split into notifyClientReady so the contract is testable.
Tests cover the PipeWriter close behaviour and assert the readyHandler
+ NotifyStatus calls receive a non-cancelled background context.
* feat(proxy): short-circuit peer-own-target loops with 421
When a peer that hosts the target of a private service dials its own
service URL the request was being looped through the proxy and back
over WireGuard to the same peer — twice the WG round-trip for no
benefit, with no signal to the caller that something was wrong.
Add isSelfTargetLoop to ReverseProxy.ServeHTTP: when the request
arrived on the per-account overlay listener (IsOverlayOrigin) and the
source tunnel IP matches the target host, refuse the request with 421
Misdirected Request and a body pointing the operator at the backend
directly.
The gate is scoped to overlay origin so requests on the public
listener that happen to share a source IP with the target host are
forwarded normally.
* fix(management): private-service validation + tunnel-IP lookup semantics
- Require an explicit port for L4 cluster targets. validateL4Target
exempted TargetTypeCluster from the port check, but buildPathMappings
serializes every L4 target via net.JoinHostPort(host, port) — port=0
shipped a ":0" upstream. Cluster targets use the same Host/Port
fields, so the same requirement applies.
- GetPeerByIP returns NotFound on a tunnel-IP miss instead of mapping
every error to Internal. The proxy's ValidateTunnelPeer probes IPs
that legitimately aren't in the roster; the miss is expected and now
distinguishable from a real store failure.
- Thread ctx into getClusterCapability's gorm query so a cancelled
request doesn't keep the store busy.
Tests updated for the L4-cluster port requirement and the GetPeerByIP
NotFound path.
* fix(client): include offlinePeers in PeerStateByIP lookup
ReplaceOfflinePeers moves peers into d.offlinePeers but PeerStateByIP
only scanned d.peers. Callers (the local DNS filter via
localPeerConnectivity, embed.Client.IdentityForIP used by the
proxy's tunnel-peer validator) were treating known-but-offline peers
as unknown, which:
- causes the DNS filter to keep returning records pointing at peers
that have no live tunnel, AND
- makes the proxy's local-roster check deny a request from such a
peer rather than letting the cached management RPC carry the
authorisation decision.
Search both slices in PeerStateByIP. Adds a unit test for the IPv4
and IPv6 offline-match paths.
* fix(rest): reject empty Delete path params in reverse-proxy clients
ReverseProxyClustersAPI.Delete and ReverseProxyTokensAPI.Delete passed
the path parameter into url.PathEscape without an empty check.
PathEscape("") returns "" which collapses the request onto the
collection endpoint ("/api/reverse-proxies/clusters/" /
"/api/reverse-proxies/proxy-tokens/"), so a caller bug delete with no
id reached a routable URL with surprising semantics (typically 405).
Short-circuit with a typed error before the request is built. Tests
mount a handler on the collection path that fails the test if hit, so
the regression is impossible to reintroduce silently.
* chore(api,ci,docs,test): private-service schema, proto-check, fixups
Non-functional cleanups and contract/CI hardening around the
private-service work:
API schema (openapi.yml):
- Require a non-empty access_groups and mode=http when private=true,
on both Service and ServiceRequest, mirroring
validatePrivateRequirements. mode stays optional-but-constrained
(empty defaults to http server-side), matching runtime.
CI (proto-version-check.yml):
- Cover renamed .pb.go files (read base via previous_filename).
- Match protoc-gen-go-grpc version headers (optional "- " prefix and
-gen-go-grpc suffix) so grpc-generated files are in scope.
Docs / comments:
- Reword Config field docs to say defaults are applied at Server.Start
(initDefaults), not New.
- Rename the obsolete --private-inbound flag to --private across
comments and the proto doc.
Pre-existing test fixups surfaced by review:
- Repair the integration-tagged validate_session_test.go (SignToken
signature growth + new Manager interface methods).
- Fix the CI-skip boolean precedence so Windows isn't skipped
unconditionally.
- Guard the router.HTTPListener type assertion with comma-ok.
* fix(proxy): background ctx for already-started AddPeer notification
The earlier ctx fix covered the async runClientStartup path but missed
the synchronous branch: when a service is added to an already-started
client, AddPeer called NotifyStatus with the caller's request-scoped
ctx. A cancelled request/stream could drop the connected notification
to management. Use context.Background() here too, matching
notifyClientReady.
Extends TestNetBird_AddPeer_ExistingStartedClient_NotifiesStatus to
pass a pre-cancelled caller ctx and assert the notification still ran
on a non-cancelled context.
