[client, android, ios] Coalesce peer list change notifications to the mobile listener (#7546)
* [client] Coalesce peer list change notifications to the mobile listener Every peer state change spawned a goroutine to call the platform listener. During a reconnect storm this pinned hundreds of OS threads in JNI and let the UI call back into the engine from each of them. Deliver peer list changes from a single goroutine per listener and collapse pending changes into the latest count. * [client] Cover a pending wake-up when the peer list deliverer is replaced The replacement test waited for the old callback to finish before swapping listeners, so it never exercised the stop check that runs after a wake-up. Block the old callback, queue a peer list change and swap while it is blocked, then assert the old listener never sees the new count. * [client] Signal peer list deliverer exit and wait for it in the test The replacement test sampled the old listener after a fixed sleep, so a late stale delivery could slip past it. Close a done channel when the deliverer goroutine returns and let the test wait on it instead. * [client] Drop the test-only peer list deliverer exit channel The done channel was only read by the replacement test. Production code cannot wait on it, since joining the deliverer would block on a mobile callback. The tests now drive the deliverer loop directly and check that setListener and removeListener close its stop channel. |

[client] Gate settings updates on value, not on field presence (#7398)
* [client] Gate settings updates on value, not on field presence
The update-settings kill switch (--disable-update-settings /
NB_DISABLE_UPDATE_SETTINGS / the MDM DisableUpdateSettings key) forbids
changing settings, but it decided what a "change" was by looking at
whether a field was present in the request. The CLI fills the whole
config surface of SetConfigRequest and LoginRequest from its flags and
environment on every `netbird up` (setupSetConfigReq in cmd/up.go), so a
client configured by environment restates its own configuration on every
start and tripped the gate every time.
SetConfig only warned about that, but Login carries the same fields and
was gated the same way, and Login runs inside the CLI's backoff loop: the
daemon answered every attempt with codes.Unavailable, `netbird up` never
completed, and a container with NB_DISABLE_UPDATE_SETTINGS plus any
config env var (NB_MANAGEMENT_URL, for one) could not come up at all.
Both gates now compare values. Config.WouldChange is the dry-run half of
UpdateConfig: it runs the very same diff logic (Config.apply) against a
copy of the stored config, so the gate cannot drift from what an actual
update would do, nor go stale when a field is added. A request that
restates what the profile already holds changes nothing and is allowed; a
request that diverges is refused exactly as before, and a dry run that
cannot be evaluated fails closed. A profile with no config on disk yet is
judged against the config the daemon would create for it.
For Login, the compared input comes from loginOverridesInput, which
persistLoginOverrides also uses to perform the write, so the gate judges
precisely the two fields a login can persist (management URL, pre-shared
key) and no field it ignores.
Two adjacent defects surfaced while making the comparison exact:
- Config.apply compared URLs as raw strings, so the same endpoint spelled
without its default port ("https://api.netbird.io" vs
"https://api.netbird.io:443") counted as a new value and rewrote the
config. It now compares the parsed forms.
- UpdateConfig did not collapse the redacted pre-shared key, unlike
UpdateOrCreateConfig and DirectUpdateConfig, so a UI round-trip of the
mask replaced the stored key with asterisks.
The CLI warning for a refused SetConfig said the method was not available
in the daemon, which sent people looking for a version mismatch that was
not there; it now reports the refusal.
* [client] Do not write the profile config while only reading it to decide
The update-settings gate needs the stored config to decide whether a request
changes anything, so the previous commit moved that read ahead of the refusal.
The read is not side-effect free: profilemanager.GetConfig writes the config
back whenever apply() has to fill in a default the file was missing. A request
that the gate then refuses had therefore already rewritten the profile file.
PeekConfig is GetConfig without that write-back. The returned config is still
normalized in memory, which is what the decision needs; the file is left
exactly as it was found. Every caller of storedConfigAtPath feeds a gate that
can refuse, so they all peek.
Note for reviewers: the daemon still normalizes the file on startup and on
every real update, so nothing depends on a read performing that write.
* [client] Compare service URLs as endpoints, not as strings
Three places in one request path each had their own notion of "same
management URL": the config layer compared the parsed URLs as strings, the
privileged-change gate compared scheme + host + effective port, and the MDM
conflict check compared strings after filling in the default port. Only the
middle one was right.
A string comparison answers the wrong question. "https://api.netbird.io",
"https://api.netbird.io/" and "https://API.netbird.io:443" are one endpoint
written three ways, so a client restating its own management URL with a
trailing slash — a normal way to write it — was still read as a client asking
to be repointed, and the update-settings gate refused it. The MDM check had
the same flaw against the enforced value.
profilemanager.SameServiceURL is now the single comparison: same scheme, same
host case-insensitively as DNS names are, same effective port. The config
layer, the privileged-change gate and the MDM conflict check all defer to it,
so there is one answer to "did this URL change?" instead of three.
* [client] Stop the config dry run from generating throwaway keys
The dry run's baseline for a profile with no config file yet went through
createNewConfig, and apply() generates a WireGuard and an SSH key whenever it
finds those fields empty. The baseline is compared against and discarded, so
every evaluation minted a keypair it threw away — and logged "generated new
Wireguard key". The CLI retries Login in a backoff loop, so a first `netbird up`
on a fresh profile filled the daemon log with what reads like peer-key rotation.
The baseline now starts from the shared skeleton with placeholder keys, so
apply() has nothing to generate. No ConfigInput field maps to either key, so
the comparison is unaffected.
* [client] Cover the login the update-settings gate used to refuse
The gate's decision procedure was tested directly, but no test drove the Login
RPC that the refusal actually broke: the CLI retries Login in a backoff loop,
so a refused no-op login is what kept a client configured by environment from
ever coming up. The handler-level coverage stopped at the refusal case, which
passes on the pre-fix code too.
This test fails on the pre-fix daemon with "update settings are disabled" and
passes now. Past the gate the handler does real work the test does not stand
up, so it asserts only that the refusal did not happen.
* [client] Re-take the update-settings decision under the config lock
Login checks twice on purpose: the first check refuses the ordinary case
early, and authorizeAndPrepareLogin re-takes the authoritative one under
guardedConfigMu because the first is unsynchronized against a concurrent
privileged request. The update-settings decision is now equally
value-dependent — it compares the request against the stored config — but it
was taken only in the first, unlocked check.
So a login that was a no-op when it was checked could be written after a
concurrent writer had repointed the profile, which is exactly the window the
lock exists to close. The decision is now re-taken alongside the privilege one,
which also makes it the last read before persistLoginOverrides writes.
The test drives that interleaving through the existing afterLoginPreCheck seam
and fails without the re-check.
* [client] Drop an unreachable guard and fix two stale comments
- loginOverridesInput's nil-message guard cannot be reached: Login
dereferences the message well before it, in storedLoginConfig.
- The docstring above afterLoginPreCheck described persistLoginOverrides,
which lives further down the file and now carries its own.
- UpdateConfig's comment named DirectUpdateConfig; the function is
DirectUpdateOrCreateConfig.
* [client] Make config reads pure and provision the identity explicitly
Reading a config wrote it back. profilemanager.readConfig persisted whatever
apply() had filled in, and ReadConfig created and wrote the file outright when
it was absent, so every reader was quietly a writer: a gate deciding whether to
refuse a request, a UI listing profiles, a mobile getter reading one preference.
The previous commit worked around that with a PeekConfig variant, which left
two read functions with opposite side effects and the antipattern still there
for everyone else.
Only one thing in a read genuinely had to be persisted: apply() generated the
WireGuard and SSH keys when it found them empty, and a generated key cannot be
recomputed — losing it means the peer comes back with a different identity and
registers again. Everything else apply() fills in is a deterministic default
that the next read recomputes anyway.
So identity provisioning is now its own step, Config.EnsureIdentity, and the
callers that provision write the result out themselves, in the open:
- Server.getConfig, the daemon's provisioning point;
- the CLI's foreground login, which is about to dial management;
- update() / directUpdate(), the config write paths — a stored profile can
legitimately carry no identity, since a mobile logout clears the keys in
place, and the next write is what has to mint a new one.
ReadConfig and GetConfig no longer write anything, PeekConfig is gone, and the
dry-run baseline no longer needs placeholder keys to keep apply() from minting
real ones.
One deliberate leftover: readConfig still calls util.EnforcePermission, which
chmods a config file whose permissions are too broad. It changes no content and
is idempotent, and dropping it would leave a legacy file world-readable until
its first write.
* [client] Name the two config readers for what they do
ReadConfig and GetConfig differed in one thing — what happens when the file is
absent — and neither name said which was which:
- ReadConfig -> ReadOrGenerateConfig (reads it, or generates one in memory)
- GetConfig -> GetExistingConfig (reads it, or fails)
Three comments went with them:
- GetConfig's said "return with Config and if it was created. Errors out if it
does not exist", which described a bool it does not return and a creation it
never performs.
- ReadConfig's explained that it does not write, which is what a reader is
supposed to do anyway.
- Server.getConfig's said it "errors out if it does not exist", which it does
not — it resolves a default config, and now provisions the identity too.
* [client] Do not panic on a config with no sync message version
apply() wrote the incoming sync message version through the stored pointer,
without checking it was there: a config that carries no version yet made it
dereference nil. Reachable from the update-settings dry run, which runs inside
a request handler — where failing closed is the worst acceptable outcome, and a
panic is not one.
The field is now reassigned like every other optional one, which also means
apply() no longer mutates anything the caller still holds through a pointer, so
the dry run's copy has one less field to detach.
Reported by cubic-dev-ai on PR #7398.
* [client] Compare the client certificate paths before reporting a change
apply() assigned the incoming mTLS certificate and key paths and set updated
unconditionally, without comparing them to what the config already held. It is
the same presence-instead-of-value mistake this branch set out to fix, one
layer down: a caller restating its own certificate paths was reported as
changing them, which trips the value-aware update-settings gate.
Reported by cubic-dev-ai on PR #7398.
* [client] Address the remaining bot findings on PR #7398
- Login logged the active-profile-state error and returned the same cause; the
repo's guidelines call for one or the other, and the wrapped error is the one
that carries context. (CodeRabbit)
- `netbird up` reported a codes.Unavailable SetConfig failure as "the daemon
refused the settings update", but that code also covers a daemon that became
unreachable. It now reports what the daemon said without asserting why.
(cubic-dev-ai)
- TestLogin_ChangingTheManagementURLIsRefused asserted the error and nothing
else, while "refused before it can touch daemon state" is the contract. It now
checks the stored management URL, the in-progress login and the active profile,
matching its SetConfig counterpart. (cubic-dev-ai)
* [client] Keep the peer identity out of a read that finds no file
ReadOrGenerateConfig resolves a default config when the profile has no file
yet, and createNewConfig was minting the WireGuard and SSH keys while doing so.
That defeated the provisioning pair it was meant to serve: the CLI's foreground
login calls EnsureIdentity to find out whether it has to persist the keys, got
generated == false because the read had already generated them, and so never
wrote them out. The login then dialed management with an identity that only
existed in memory, and the next login registered a second peer.
createNewConfig no longer provisions. createProvisionedConfig is the variant
that does, and the callers whose contract is "usable as it comes back" use it:
CreateInMemoryConfig, whose callers connect with the result, and the two
create-and-write branches. A read gets a config with no identity, so the
caller's own EnsureIdentity reports the work and triggers the write.
Reported by CodeRabbit and cubic-dev-ai on PR #7398, both on the same defect.
* [client] Stop the gate test from dialing the real management server
TestLogin_RestatingTheStoredConfigPassesTheGate asserts that the gate lets a
no-op login through, and the handler then went on to do the login for real:
isLoginRequired builds an auth client when isLoginRequiredFn is unset, so the
test dialed the profile's management URL — api.netbird.io:443. It took 1.05s
locally and would hang on a runner with no egress, for a fact about the gate
that needs no network at all.
Stubbed like the login_outcome tests do. The test now runs in 0.00s.
Reported by cubic-dev-ai on PR #7398.
* [client] Keep the admin panel path part of its identity
The endpoint comparison introduced for the management URL was applied to the
admin URL too, and that one is opened in a browser rather than dialed over
gRPC: a panel served under /netbird is not the panel served at the root. So a
config whose admin URL differed only by path reported no change, and the new
path was never persisted — a custom panel URL could not be updated at all.
SameServiceURLIncludingPath adds what a URL carries past its endpoint (path,
query, fragment, userinfo) while still treating equivalent spellings as equal:
a missing path and "/" are the same root, and so is a trailing slash. The
management URL keeps the endpoint-only comparison, since only the endpoint is
ever dialed.
Ports are also normalized numerically now, so ":0443" and ":443" are one port.
Reported by cubic-dev-ai on PR #7398 (two findings).
* [client] Treat a profile with no identity as already deregistered
Two findings on the same consequence of pure reads: a profile can legitimately
carry no keys, because logging out clears them in place.
- sendLogoutRequestWithConfig went straight to wgtypes.ParseKey and failed with
"incorrect key size: 0" on the second logout of the same profile. There is
nothing to deregister for a peer that was never registered, so it returns
cleanly. Before pure reads this case was hidden: the read minted a key and
the daemon dialed management with one it had never seen.
- The mobile logout read the config with the generating reader right after
checking the file exists. The two are not atomic, so a profile removed in
between was resolved from the defaults and recreated by the write that
follows. It uses the existing-file reader now.
Reported by cubic-dev-ai and CodeRabbit on PR #7398.
* [client] Fail `netbird up` when the daemon refuses the settings update
With the update-settings kill switch on, `netbird up --enable-rosenpass`
connected and said almost nothing: SetConfig refused the change, the CLI
downgraded that to a warning, and Login carries no rosenpass field to apply, so
the flag was silently dropped. The setting stayed disabled, which is the point
of the switch, but the caller was never told their request had been ignored.
The refusal now travels as codes.FailedPrecondition instead of
codes.Unavailable, and the CLI fails on it. Unavailable means "the daemon
cannot serve this call", which is why the CLI downgraded it and why
client/ui/services reads it as an unreachable daemon — both wrong for a daemon
that answered and refused. FailedPrecondition also matches what the MDM gate
already returns for a managed field, so both refusals are now one class of
error, and it is added to the login backoff's early-exit codes so a refused
login stops instead of retrying for 30s.
This does not put the container back in the deadlock: with the value-aware
gate, a client restating its own configuration is not refused at all, so
nothing reaches this path unless a real change was asked for.
* [client] Name the reader storedConfigAtPath actually calls
The purity note still said profilemanager.GetConfig, which the rename two
commits later turned into GetExistingConfig.
Reported by cubic-dev-ai on PR #7398.
* [client] Restore the gofmt alignment of the error constants
The comment added above errUpdateSettingsDisabled in the previous commit split
the const block's alignment group, so gofmt wants the two constants above it
re-aligned. CI runs gofmt, so this would have failed the lint job.
* [client] Let an unprivileged caller log out a profile with no identity
The empty-key check sat behind requirePrivilegeForDeregistration, so an
unprivileged logout of an identity-less profile was refused with
PermissionDenied instead of completing as the no-op it is. And it was refused
for most profiles, not a corner case: the gate arms whenever the SSH server is
enabled, and sshServerEnabled reads an absent ServerSSHAllowed as enabled, so
every legacy profile qualifies.
The check now runs first. What the gate protects against is handing this
machine's registered key to another management server; with no key there is
nothing to hand over and nothing to protect.
Reported by CodeRabbit and cubic-dev-ai on PR #7398, both on the same defect.
* [client] Stop `netbird login` from retrying a refusal for 30 seconds
`netbird up` and `netbird login` both run Login through the backoff cycle, and
each carried its own copy of the list of codes that end it. Only up.go learned
about codes.FailedPrecondition, so a refused `netbird login` kept retrying and
then reported "login backoff cycle failed" instead of what the daemon said.
terminalLoginError is now that list, once, next to WithBackOff — the duplicated
copies are what let the two commands disagree in the first place.
Reported by cubic-dev-ai on PR #7398.
* [client] Answer terminalLoginError's nil case on its own terms
A successful Login reaches terminalLoginError with a nil error, and nothing
covered that. It happens to work on grpc v1.80.0 — gstatus.FromError(nil)
answers (nil, true), and Status.Code tolerates a nil receiver by returning
codes.OK, which is not in the terminal set — but that is a chain of internal
details to be relying on for the common path, and none of it was asserted.
Now the nil error is handled where it is obvious, and the table covers it.
Reported by CodeRabbit on PR #7398, which called it a panic; measured on
v1.80.0 it is not one. The gap was the untested reliance, not a crash.
* [client] Treat an unset optional field as its default when diffing a config
Seven Config fields mean "the effective default" when they hold no value:
the five SSH toggles, the SSH JWT cache TTL, and the network monitor. Every
consumer already reads a nil as that default, but apply() diffed them by
presence — `config.X == nil || *input.X != *config.X` — so an input restating
the default counted as a change.
That made the update-settings gate refuse `netbird up` outright. The CLI
sends every flag whose value came from an environment variable
(SetFlagsFromEnvVars goes through pflag's FlagSet.Set, which marks the flag
Changed), and the config a plain login writes leaves all seven unset, so a
container configured with, say, NB_ENABLE_SSH_ROOT=false restated a default
the file held as null on every start and was answered with
FailedPrecondition.
apply() now resolves the seven up front, the way it already did for
ServerSSHAllowed and RemoteJobsAllowed, which also repairs such a profile on
its next write. With the values named, the comparisons below diff values
instead of presence, so their nil branches are gone.
The network monitor keeps its platform default — on for windows and darwin —
and naming it as false elsewhere is what createEngineConfig already read a
nil to be. getJWTCacheTTL reaches the same 0 through its own default, and
Android's GetEnableSSH* getters already answered nil with false.
* [client] Normalize the config before diffing it in WouldChange
apply() reports two different things through one bool: an input that changed
a value, and a field it had to fill in because the config carried none. The
update-settings gate reads that bool as "the caller asked for a change", so
any config still missing a default answered a request that asks for nothing
with a refusal.
Readers already hand out normalized configs — readConfig applies an empty
input for exactly this reason — which is why the gate got away with it. But a
handler that refuses a request must not depend on where its caller obtained
the config, and it must not start reading "this profile predates a field" as
"the caller asked for a change" the day someone adds one with a default.
WouldChange now runs the filling-in as a pass of its own and discards its
verdict, so the pass that answers the caller measures only what the input
did.
* [client] Stop the last config write that skipped normalization
Every path that creates or updates a profile config goes through apply(),
which resolves an optional field to its default — except RenameProfile,
which read the file with a bare json.Unmarshal, set the name, and wrote it
straight back. That copied whatever the file held, so a config written by a
client that stored these fields as null kept them null. It could not
introduce a null, only carry one forward, but renaming a profile is a poor
place to leave a half-resolved config behind. It now reads through
GetExistingConfig, which normalizes what it hands out.
The tests state the invariant the fix completes, over the *bool fields of
Config listed by reflection so a field added later is covered without
touching them: none may come out of apply() unset, and no write may store
one as null. An optional bool that can be nil, true or false forces every
reader to invent the meaning of nil, and makes a diff of the config compare
presence rather than value — which is exactly what refused `netbird up` for
a client restating its own defaults.
SyncMessageVersion stays a genuine three-state field and is not covered: it
is an *int whose absence means the client pins no version, and it travels to
management that way.
* [client] Refuse a serialized config that carries no peer identity
ConfigFromJSON still promised a "fully initialized" config after this PR
moved key generation out of apply() into EnsureIdentity, but identity stopped
being one of the defaults it applies. Its two callers both connect with what
they get back: the iOS SDK's Client.SetConfigFromJSON keeps it as the
preloaded config Run() uses on tvOS, and Auth.SetConfigFromJSON as the config
it authenticates with.
No caller feeds it a document without keys today — every stored document
comes from Auth.GetConfigJSON, whose config is provisioned by
DirectUpdateOrCreateConfig or CreateInMemoryConfig, and the tvOS app only
ever edits fields of a document it already has. This is a safety net for the
next caller, not a live bug.
Provisioning the identity here would be the wrong net. Neither caller can
hand a generated key back to the store the document came from — Client
exports no config at all — so the peer would connect under an identity
nothing persists and register anew on every launch, which is the failure the
EnsureIdentity split exists to prevent. A document with no identity means
nobody has logged in yet, and saying so is the only useful answer.
Both keys are required because both are dead ends when missing: an empty
WireGuard key fails the management login on its size, and an empty SSH key
fails ssh.GeneratePublicKey in ConnectClient before the engine starts.
* [client] Say that the null-on-disk fixture is synthesized, not written
The test comment described the null state in the present tense — "the config
a plain login writes leaves every one of them unset" — which was true before
this branch and is not any more: apply() now resolves those fields, so a
login writes them set. unsetOnDisk puts the null state back deliberately, to
stand in for a profile an older client wrote. Comments only.
* [client] Gather the optional-field defaults into one function
Resolving an unset optional field was spread over five places: the two
values newConfigSkeleton pre-sets, the block this branch added for the SSH
toggles, the network monitor's own if, the `else if` tails of
ServerSSHAllowed and RemoteJobsAllowed, and a trailing if for
DisableNotifications several hundred lines further down. Reading apply() left
no single answer to "what does this field default to, and who decides".
They now live in Config.resolveUnsetDefaults, which apply() calls before it
compares anything — the ordering being the point, since it is what lets
every comparison below diff values instead of presence. The comparisons for
ServerSSHAllowed, RemoteJobsAllowed and DisableNotifications lose their
`config.X == nil ||` clauses accordingly, as the other six already had.
newConfigSkeleton keeps its two, and that is the one asymmetry worth naming:
ServerSSHAllowed defaults to false for a new profile and to true for a
legacy one, and it only works because the skeleton runs first. The doc
comment says so, where before it was implied by the order of two distant
blocks.
Pure refactor. Verified as one: for the four fields whose branches moved,
plus two that did not and the JWT TTL, all 63 combinations of stored value
(nil/false/true) against input value (absent/false/true) produce byte-
identical resolved values and `updated` verdicts before and after.

[client] Skip late session warnings on desktop and schedule them in the app on Android (#7548)
* Skip session warnings that fire after their window The warning timers run on the monotonic clock, which does not advance while an Android device is suspended. A timer armed for T-10 or T-2 can therefore fire long after the window it was armed for, delivering a "session expires soon" notification once that window is already gone. Gate both callbacks on the wall clock at fire time: the T-10 warning is skipped once the final-warning window has been reached, and the final warning is skipped once the deadline itself has passed. Both set their edge guard before returning so a skipped warning cannot fire again for the same deadline. * Harden the late-warning guards Clamp a non-positive final lead to zero in the T-10 guard so a disabled final warning cannot move the cutoff past the deadline, matching how armTimerLocked already treats it. Strip the monotonic reading from both sides of the comparison so the guard measures wall-clock time regardless of how the caller built the deadline. The production deadline comes from a protobuf timestamp and has no monotonic reading; this keeps the guard correct for callers that derive one from time.Now. * Log the deadline and lateness on skipped warnings Include the deadline and how far past the cutoff the timer fired, so a debug bundle shows how long the device was suspended. * Inject the clock into the late-warning guard and cover it with tests The guard read time.Now internally, so the skip paths were reachable only through a deadline already in the past and the boundary depended on real time. Extract the comparison into isLate and read the time through a nowFn field, so tests can place a resume anywhere around the deadline without sleeping. * Send the final warning when the T-10 timer fires inside its window A suspend between roughly eight and ten minutes long made the T-10 timer fire inside the final-warning window and the final timer fire after the deadline, so both were skipped and a user who resumed with time left got no warning at all. When the T-10 timer fires late but before the deadline, send the final warning in its place and mark it fired so the delayed final timer does not repeat it. * Respect dismissal when promoting a late warning to the final one fireFinal skips the final warning once the user dismissed the deadline, but the promoted path did not, so a dismissed deadline could still get a final warning. Check the dismissal first, and give each skip reason its own log line so an already-fired final warning no longer logs a negative lateness. * Add a deadline-only mode to the session watcher Android will schedule its own expiry warnings from the deadline, so the engine must not arm the T-10 and T-2 timers there. NewDeadlineOnly keeps the deadline validation, the recorder propagation and the logging, and skips only the timers, so the status snapshot the app reads stays correct and an out-of-range deadline is still rejected. * Use the deadline-only watcher on Android and drop the warning callbacks The warning timers run on the monotonic clock, which does not advance while the device sleeps, so a warning armed for T-10 could fire long after its window. The app now schedules the warnings itself with WorkManager, anchored to the wall clock, from the deadline it reads through SessionExpiresAtUnix on every OnStateChanged. Wire the deadline-only watcher into the android build and remove the event-driven path from the gomobile surface: OnSessionExpiring, the event subscription behind it and DismissSessionWarning, which the app never called. * Describe the late-warning guard without naming Android The guard stays for the desktop builds, where a timer can also stall across a sleep. Android no longer arms the timers at all. |

[client] stop offering to every peer when the relay transport drops (#7092)
* [client] stop offering to every peer when the relay transport drops The relay transport is shared: one connection per relay server carries the streams of every peer using it. When it drops, each of those peers gets a Disconnected verdict from evalConnStatus even when ICE is still carrying its traffic, because peerUsesRelay comes from HasRelayAddress(), which only reports that management offered relay servers, not that we are connected to one. The guard answers Disconnected with the aggressive retry, so every peer starts sending offers over signal for a transport that no offer can restore: the relay client's own guard is what reconnects it. Feed relayManager.Ready() into the status inputs and return PartiallyConnected when ICE is up and the missing side is the shared transport. That is the existing "one path works, the other does not" branch, which retries three times and then hourly instead of walking the exponential ladder forever. Peers are not left waiting for the hourly tick: when the transport comes back, Manager.onServerConnected notifies srWatcher, the guard resets the ticker to 800ms and iceState.reset() clears the hourly mode. The verdict is unchanged when the transport is up but this peer is unreachable over relay - it may have moved to another server, and only an offer carries its new relay address - and in force-relay mode, where relay is the only transport. * Renaming according to actual meanings * Don't consider an in progress ICE as "partially connected" when the relay is not.. * Aligns tests * Address wrong comments |

[client] Fix browser login popup show from go (#7408)
* [client] Show the SSO login popup and open the browser from Go The browser-login popup was created hidden and relied on its own webview to size and show itself and to launch the external browser. On macOS a hidden WKWebView gets throttled or suspended (App Nap / hidden-window throttling), so on the first-use path nothing appeared and the browser never opened, leaving the session-expiration dialog disabled until the PKCE flow timed out. Reproduced by freezing the popup's WebContent process: the old code showed nothing, the new code shows the popup and opens the browser within 30 ms regardless of the webview state. Show and focus the popup from Go right after creation and launch the browser from Go on both the create and reuse paths. The popup's frontend no longer shows or focuses itself, so the browser keeps the foreground once it activates. This also fixes the reuse path, where a fragment-only SetURL kept the mounted React tree and the once-only guard skipped opening the browser for the new URI. Browser launch failures surface in the error dialog instead of being swallowed. * [client] Show every dialog window from Go once its frontend has painted Dialog windows (browser-login, session-expiration, install-progress, welcome, error) were created hidden and made visible only by their own webview's Show call after sizing. A hidden WKWebView on macOS can be throttled or suspended before that code runs, which left the window hidden forever. The main and settings windows already avoided this with the painted event plus a fallback timer, but that timer was armed on WindowRuntimeReady, which a frozen webview never reaches either. Route all dialogs through the same mechanism: the auto-size hook emits the painted event instead of showing the window, Go shows and focuses it on that event, and a fallback timer armed at creation shows it after 3 s regardless. The browser-login popup opens the browser in an after-show callback so the browser still lands in front of the popup, also on the fallback path. * [client] Tie install-progress hidden-window restore to the current popup CloseInstallProgress nils s.installProgress before calling w.Close(), so a replacement popup can open before the old window's WindowClosing event runs. The old callback then restored the windows the replacement had just hidden, because the restore sat outside the identity check. Guard the restore with the same check the state reset uses, and restore from CloseInstallProgress itself so the programmatic close path still re-shows the hidden windows — mirroring how CloseBrowserLogin already handles it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * [client] Correlate painted reports with the window generation that sent them A painted report carried only the window name, so a late report from a popup that was already closed and replaced marked its replacement ready. The replacement was then shown before its own frontend had rendered, which is the blank-dialog case this flow exists to prevent. Each dialog start URL now carries a monotonic generation token, echoed back by ReadySignal, and a report whose token no longer matches the live window is dropped. * [client] Separate a window being painted from its frontend being mounted One flag gated both showing a window and emitting to it, so the fallback timer set it for a frontend that had not subscribed yet: the queued events were flushed into a window that could not hear them, losing the login trigger and the settings tab selection. Showing is now gated on painted and emitting on mounted, and only a real frontend report sets mounted. The fallback timer also moved to its own helper so the runtime-ready hook can rearm it, giving the frontend a full budget to mount rather than sharing one with webview boot. * [client] Tag hidden windows with the popup that hid them Windows hidden while a popup owned the screen went into one untagged list, so whichever popup closed first restored all of them and emptied the list. An install started during SSO login re-showed the main window the login popup had deliberately hidden, and left the login popup with nothing to restore. Each entry now records the popup that hid it, and a restore releases only that popup's own entries. This also subsumes the manual filtering CloseRenewFlow did to keep its own session-expiration window from being re-shown. * [client] Cover the hidden-window bookkeeping with tests application.Window carries unexported methods, so the hide/restore paths could not be faked and the earlier tests could only assert which entries survived a restore, never which windows were actually shown. The bookkeeping now goes through hideableWindow, the four methods it needs, with the window enumeration and the main-window raise behind seams that are nil in production. That makes the case the owner tag exists for testable end to end: an install started during SSO login restores only the login popup it hid, and leaves the main window hidden until the login popup itself closes. * [client] Report the first paint from unstamped windows too The main and settings windows carry no generation token, so ReadySignal saw an empty generation that already matched the ref's initial value and never emitted the painted event. Those windows only became visible through the fallback timer, and their frontend was never marked mounted, so the login trigger and the requested settings tab stayed queued. Start the ref from null so the first report goes out regardless of the generation value. * [client] Hand covered windows over when a popup closes under another Closing the browser-login popup while the install-progress popup was still up restored the main window the login had hidden, even though the install popup was meant to own the screen until it finished. The owner tag on each hidden entry only stops a popup from restoring another's windows; it says nothing about what to do with its own when a second popup still covers them. Track which popups currently own the screen and, on restore, re-tag the entries another live popup covers to that popup instead of showing them. A popup is never handed its own window, so closing the popup on top still brings the one below back. --------- Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com> |

[client] Resolve the Android network route peer by HA unique ID instead of scanning the full status (#7705)
* [client] Build the Android network list from a single peer snapshot Networks() called GetFullStatus() once per network to find the peer that serves it, copying every peer state and taking eight recorder locks each time. With 100+ peers and the UI calling Networks() from every peer list change, this queued hundreds of callers on the status recorder lock. Take one snapshot per call and index it by route. * [client] Track the active route peer by HA unique ID in the status recorder The Android network list resolved the route owner by scanning peer state route keys. Those keys are the handler string: a prefix for static routes and the domain pattern for dynamic ones, so the prefix-based lookup never matched dynamic routes, and two networks sharing a prefix resolved to the same owner. The route watcher now records the chosen route peer under the route's HA unique ID in the status recorder, and the Android binding looks the owner up by that ID. The key is unique per network and independent of the handler string format, so both anomalies are gone. The prefix-based routeOwners helper is removed. * [client] Record the active route peer before notifying listeners AddPeerStateRoute and RemovePeerStateRoute fire the peer list change callback and wake the status subscribers. The active route peer mapping was written after those calls, so a Networks() call landing in between found no mapping for the network and fell back to the first connected peer, or kept showing the previous peer on removal. Nothing re-notified after the mapping write, so the wrong peer stayed until the next peer list change. Write and delete the mapping before the notifying calls so a listener reacting to the notification always reads the current owner. |

[client,android] Generate debug bundle to file (#7528)
* [client] Add a debug bundle file export to the Android bridge The Android app can only upload a debug bundle and hand the user a key. Users who want to inspect what leaves their device before sharing it have no way to get the zip itself. Add DebugBundleFile, which generates the bundle into the cache directory and returns its path instead of uploading; the app copies it wherever the user chose and removes it. DebugBundle keeps its behavior. Both entry points share the unexported debugBundle with an upload switch, so the body stays where it was and merges cleanly with the MDM overlay change on main. Because the file variant leaves the zip to the caller and the upload variant only removes it after the upload finishes, a process killed in between leaves a zip behind in the cache. Remove stale bundles before generating a new one: RemoveStaleBundles deletes zips matching the generator's pattern that are older than an hour. Remote debug jobs write to the same directory, so younger files are treated as still in use. * Preserve network map for debug bundle on Android * [client] Keep exported Android debug bundles out of the stale cleanup DebugBundleFile hands the zip to the caller, but the file kept the netbird.debug.*.zip name that RemoveStaleBundles matches, so a later debug run could delete it once it was older than an hour. Rename the exported bundle to netbird.debug-file.*.zip after generation so the cleanup only ever touches bundles no caller owns. * [client] Warn when a stale debug bundle cannot be removed A failed removal means bundles pile up in the cache directory, so log it at Warn instead of Debug. A file that is already gone was removed by a concurrent cleanup and is skipped silently. * [client] Drop the outdated debugBundle comment The comment still said the file variant leaves the zip in place, but it is renamed by debug.ExportBundle since the stale-cleanup change. * [client] Test that the network map reaches the debug bundle Cover both halves of the path Android now relies on: the engine keeps the latest sync response once persistence is enabled, and the bundle generator writes it to network_map.json (anonymized or not) and omits the file when there is no sync response. * [client] Remove abandoned exported debug bundles after a day An exported bundle is owned by the caller, but if the app is killed before it copies and deletes the file, nothing ever removes it from the cache directory. Let RemoveStaleBundles also match exported bundles, with a 24 hour max age instead of the caller-provided one, so a bundle that is still being saved survives while an abandoned one goes. |

[client] Discover interfaces lazily in stdnet instead of at construction (#7346)
* [client] Discover interfaces lazily in stdnet instead of at construction
stdnet.NewNet and NewNetWithDiscover ended with
return n, n.UpdateInterfaces()
handing back a non-nil *Net together with the discovery error. Three of the
five call sites (Engine.newWgIface, ice.NewAgent, SingleSocketUDPMux) logged
the error and kept using the instance, which is only safe as long as the
instance still works after a failed discovery.
That stopped being true when Interfaces() gained a lazily refreshed cache:
updateInterfaces sets lastUpdate only on success, so after a failed
construction the 30s cache guard never holds and Interfaces() returns an
error rather than the empty list it used to return. Feeding such an instance
to pion is worse than passing nothing at all - ice.NewAgent falls back to its
own stdnet when Net is nil, and the interface blacklist is applied separately
through AgentConfig.InterfaceFilter, so the fallback loses nothing. Instead,
a transient discovery failure (the Android bridge at boot, or an interface
disappearing between net.Interfaces() and Interface.Addrs()) turned into a
hard "error getting local interfaces" from ice.NewAgent, and aborted the STUN
and TURN probes, which never even need the interface list.
Since the accessors already refresh a stale cache on demand, the eager
discovery in the constructors is redundant: drop it, make both constructors
infallible, and let the discovery error surface at the call that actually
needs the interfaces. UpdateInterfaces had no callers left and is not part of
transport.Net, so it is removed along with it.
InterfaceByIndex and InterfaceByName read the cached slice directly and never
refreshed it, so they would have kept reporting ErrInterfaceNotFound forever
on an instance whose first discovery failed. They now go through the same
refresh path as Interfaces().
* [client] Warm the stdnet interface cache at construction
Moving discovery to first use regressed the privileged suites on the three
platforms that always build an ICE bind: Darwin, FreeBSD and Windows time out
in TestWGIface_UpdateAddr, TestRecreation, TestEngine_SSH and
TestEngine_MultiplePeers, while Linux stays green because a host with the
WireGuard kernel module takes the kernel-device branch and never drives the
mux that asks for interfaces.
interfaceFilter probes with wgctrl every interface the disallow list does not
already exclude. Discovering at construction ran that probe before the caller
had an overlay interface of its own; discovering at first use runs it after,
so on a userspace WireGuard platform the probe reaches the UAPI socket of the
same process. The tests reach it because they construct with a nil disallow
list, where the client passes DefaultInterfaceBlacklist and its own interface
is excluded by prefix.
Restore the original timing with an explicit warm-up. The constructors stay
infallible and the error is still reported by the accessor that needs the
interfaces, so the contract this branch is about is unchanged.
* Revert "[client] Warm the stdnet interface cache at construction"

[client] Report both peers' state when the connect test times out (#7944)
Test_ConnectPeers fails every few weeks on the Linux runner with a bare "waiting for peer handshake timeout after 30s". The failing logs show both kernel devices up and both peers configured within a second, then nothing for 30 s, which is six retries of the 5 s handshake retransmit and so a condition that lasted the whole window rather than a race. The failure cannot be reproduced locally and the log cannot tell whether initiations were sent, whether they arrived, or whether only one direction worked. On timeout the test now prints each device's view of its peer, the endpoint, the byte counters and the last handshake, so the next failure says which of those it is. The comment also states that the peers are kernel devices on the runner and that the first initiation of each side is always lost to the other side not knowing the peer yet. |

[client] Add Homebrew cask e2e test (#7618)
* [client] Migrate macOS cask template to Homebrew install steps
Homebrew deprecated the postflight and uninstall_preflight cask stanzas
in favour of the declarative *_steps DSL, so every brew command that
evaluates netbirdio/tap now prints deprecation warnings. Once the
deprecation becomes a disable the generated cask stops loading and
netbird-ui can no longer be installed or upgraded through Homebrew.
The *_steps blocks take JSON-serialisable steps run in a sandbox rather
than arbitrary Ruby, so system_command is re-expressed as run/remove.
The two postflight blocks merge into one because a cask carries only a
single instance, preserving the original order. set_permissions moves
from a hardcoded /Applications to base: :appdir, matching what the
installer invocation already did. The launchctl fallbacks keep their
tolerant semantics through must_succeed: false, and remove is a no-op
when the plist is absent.

[client] Keep the advertised ICE session ID when following a remote restart (#7814)
A worker that saw a new remote session ID rebuilt its agent and also picked a new local ID. On the answer path nothing carries that ID back, so the next offer made the remote see a changed session, rebuild, and answer with yet another ID. Two peers kept tearing down working ICE connections on every offer and answer; nearly every answer in the affected logs carried a new remote session ID. Only a local restart changes the local ID now: a failed negotiation, as before, and an explicit Close, which previously kept the old ID and left the remote answering from a negotiation this side had abandoned. Following a remote restart keeps the ID the remote already knows, so the pair settles after one rebuild, also against peers that still pick a new ID when following a restart. |

[client] Keep the delete-profile dialog open until the delete finishes (#7752)
* [client] Keep the delete-profile dialog open until the delete finishes Confirming a profile deletion closed the dialog straight away and left the daemon call running in the background. A slow delete then looked like nothing had happened: the dialog was gone, the profile was still listed, and the row only disappeared whenever the refresh landed. The confirm dialog now owns the action. It stays open with the confirm button spinning, closes once the call resolves, and surfaces a failure after it is gone rather than behind it. Nothing on the daemon path carries a deadline, so the wait is bounded in the dialog instead: Cancel comes back after five seconds and the wait is abandoned at thirty, which keeps a hung daemon from trapping the user in a modal that cannot be dismissed. A loading button keeps its own variant colours rather than the disabled skin, which dimmed the spinner to grey on the danger variant, and blocks input through aria-disabled and a click guard instead. * [client] Match the theme and anonymize pickers to the language switcher * [client] Settle a confirm dialog only from the run that opened it Cancelling at the stall point leaves the action running, and the provider is mounted once: take() read whichever settler the ref held when the stale run finally finished. Open another prompt in the meantime and that run answered it — a hung delete that later resolved confirmed a profile switch nobody accepted, and its timeout closed the new dialog with an unrelated error. Each run now remembers the settler it was dispatched for and settles only while the ref still points at it. A late arrival finds a stranger there and answers nothing. * [client] Add the shared Select the theme and anonymize pickers use The picker rework landed without the component both pickers import, so the branch did not compile. Add it, and name it for what it is: a select of a few options, with nothing settings-specific about it, so it sits with the other input controls rather than under a name that discourages reuse. * [client] Drop the Select header comment * [client] Fix cubic comments * [client] Name the Select trigger with the option it is showing * [client] Name the language trigger with the language it is showing * [client] Hold the confirm dialog for 15s before offering cancel |

[client] Stop dumping the whole device to clear one peer endpoint (#7632)
* [client] Stop dumping the whole device to clear one peer endpoint Clearing a peer's endpoint has to remove and re-add the peer, because neither the netlink API nor the wireguard-go UAPI can clear an endpoint in place. To keep the peer's allowed IPs across that dance, RemoveEndpointAddress read them back from the device: a full wgctrl.Device() dump on the kernel path, a full IpcGet plus text parse on the userspace one. Both cost a round trip proportional to the entire network map, both run under the interface lock, and both run on every relay and ICE transition. On a routing peer with ~15700 peers that is megabytes of netlink traffic per transition, at a measured 713 transitions per minute, with every other configuration operation queued behind it. RemoveAllowedIP paid the same price for the same reason. The allowed IPs cannot come from the caller: peer.Conn knows the peer's own overlay addresses, while the routed prefixes are attached separately by the route manager's refcounter, so a caller-supplied set would silently drop every route behind the peer. The configurer is the only writer of its device's peer set, so it can keep an authoritative mirror of what it configured and answer from memory instead. The mirror is fed by every operation that changes a peer's allowed IPs and reset by a device reconfiguration that replaces the peer set. A peer the mirror has not seen, which is what an out-of-band reconfiguration leaves behind, still falls back to reading the device and seeds the mirror from it. Prefixes are unmapped on the way in, so a v4-mapped address compares equal to the plain v4 prefix for the same network rather than registering as a second entry. Measured on a userspace device, allocations to clear one endpoint: peers 64 256 1024 4096 before 1452 - 21617 - after 91 91 91 91 * [client] Keep update-only allowed IP adds out of the peer mirror AddAllowedIP configures the device with update_only, which is a silent no-op when the peer does not exist, so its success says nothing about whether the device took the prefix. Recording it unconditionally let the mirror hold a peer the device had dropped, and RemoveEndpointAddress re-adds a peer without update_only: clearing the endpoint of such a peer recreated it, carrying allowed IPs the device never held. Allowed IPs are unique per device, so the recreated peer takes those prefixes away from the peer that legitimately holds them. This is not a theoretical window. Under lazy connections a routing peer's device entry is torn down and re-created on the idle transition, and a routed prefix re-added during that window is lost exactly because of update_only (#6863). Allowed IP adds now merge only onto a peer the store already knows, which mirrors the device: the operations that can create a peer record it, the update-only ones do not. A peer missing from the store still falls back to reading the device. * [client] Hand a prefix over to its new owner in the peer mirror An allowed IP belongs to exactly one peer: configuring a prefix on a peer takes it away from whichever peer held it before, and the configurer leaves that handover to the device rather than removing the prefix from the previous holder itself, which is what UpdatePeer's "wg will handle duplicated peer IP" refers to. The mirror recorded the prefix on the new peer while leaving it listed under the old one, so clearing the old peer's endpoint rewrote its allowed IPs from that stale list and took the prefix back from the peer that now owns it. Traffic for the routed prefix then went to the wrong peer. Reading the device before each write used to rule this out. The store now tracks the owner of each prefix and performs the same handover, so rewriting one peer's list cannot reclaim a prefix another peer holds. Prefixes are also masked on the way in. A device stores them masked, so a caller passing host bits would otherwise fail to match what a device fallback seeded and could never remove that prefix by value. Conversion back from the device now keys the v4-mapped decision on the mask width as well, so a genuine v6 prefix inside the mapped range stays v6 instead of being dropped as an invalid v4 prefix. * [client] Keep a mapped v6 prefix below /96 out of the v4 form normalizePrefix unmapped any v4-mapped address before masking it, keeping the original prefix length. For a genuine v6 prefix inside the mapped range, such as ::ffff:0:0/64, that pairs a v4 address with a v6 sized mask: netip.PrefixFrom returns an invalid prefix and Masked turns it into the zero prefix. The store then held a prefix whose Bits is -1, which cannot reproduce the allowed IP the device was given, so re-adding the peer after an endpoint removal could fail once the peer had already been removed. Masking now comes first, and it also decides the address family: only a prefix at least 96 bits long keeps the mapped marker through the mask, so anything shorter inside that range is v6 and stays v6. * [client] Record a peer created by a preshared key write Setting a preshared key without updateOnly creates the peer when it is absent, and Rosenpass applies a peer's first key exactly that way, since applyKeyLocked passes the peer's initialized flag. The store ignored that operation, so the peer could exist on the device while the store treated it as unknown. An update-only allowed IP add on such a peer then succeeded on the device, which moved the prefix away from its previous holder, while the store skipped the peer and left the previous holder still claiming it. Clearing that holder's endpoint rewrote it from the stale claim and took the prefix back, leaving the peer that owns the route with nothing. Every device operation that can create a peer now records it, which is the same rule the update-only operations already follow from the other side. * [client] Match a peer on the parsed key instead of its base64 form getPeer scanned the device comparing Key.String to the caller's key. wgtypes.Key is a 32 byte array, so it compares directly, while String base64 encodes it into a fresh allocation on every iteration. The scan therefore allocated once per peer on the device to find a single peer, and on a large network that is tens of thousands of allocations per lookup. The key is parsed once up front and the arrays are compared. Behaviour is unchanged: the callers already parse the same key before reaching here, so the new parse error is unreachable in practice and only guards the helper on its own. * [client] Normalize prefixes on their way to the device Prefixes were normalized when recorded but not when written, so a caller's raw prefix reached the device while a different form was kept for it. The conversion is also where a mapped prefix goes wrong: net.IPNet prints a v4-mapped address as v4 but takes the length from its 16 byte mask, so ::ffff:10.1.2.3/64 is handed to a userspace device as 10.1.2.3/0 — an allowed IP matching every v4 address, on a peer that was meant to carry one /64. prefixesToIPNets now normalizes, and the two hand-built conversions in AddAllowedIP go through it, so there is a single place where a prefix is turned into something a device is given and it cannot disagree with what is recorded for it. * [client] Parse the endpoint before configuring the peer The userspace UpdatePeer parsed the endpoint address after the device had already been configured, and returned on a parse failure. The device was then left holding a peer that neither the activity recorder nor the allowed IP store had been told about, so the peer was invisible to the wake path and the prefix handover for its allowed IPs never happened, leaving the previous holder still claiming them. The parse now happens before anything is written, so the only failure left after the device is touched is one the caller cannot cause. * [client] Keep the record when a peer removal fails The two configurers disagreed: the kernel one dropped its record only once the device had accepted the removal, the userspace one dropped it either way. Removing a peer is a single device write, so a failure leaves the peer exactly as it was, with the allowed IPs the record still describes. Dropping it there asserts nothing useful and only sends the next caller to read the whole device back for an answer it already had. The userspace one now follows the kernel and returns early on failure. * [client] Write down what the allowed IP store does not guarantee Two properties were relied on without being stated. The store's lock covers its map and not the device write beside it, so consistency between the two rests on callers being serialized, which WGIface does with its mutex; anyone removing that would have no way to learn it mattered. And the fallback to the device only covers a peer the store has never seen, so a peer first recorded from empty while the device already held prefixes keeps only what was recorded, and the next endpoint removal drops the rest. * [client] Key the allowed IP store on the parsed peer key The store keyed on the textual key, so a lookup compared 44 byte strings while the callers all held the parsed key already and the configurer had to carry both forms. wgtypes.Key is a 32 byte array and compares directly, which is what getPeer was changed to do for the same reason. The store and its helpers now take wgtypes.Key, the callers pass the key they parsed on entry, and the textual form survives only where something outside speaks it: parseStatus reports peers that way, so the userspace fallback converts once for its scan. * [client] Document the configurer methods the store changed The exported configurer methods now carry what the allowed IP store made true of them: when the mirror is reset, that a peer update merges its prefixes and takes them from their previous owner, that an update-only add on an absent peer does nothing, and what each side does with its record when a device write fails — where the two configurers differ, since the userspace one reports a prefix it does not have and the kernel one treats it as a no-op. mergeLocked states the lock its callers must already hold. Docstrings that only restated the name of a test are left out; the tests explain the scenario they set up in the body, where the explanation belongs. |

A detailed status carries an entry per peer, so on a large deployment the response outgrows that cap and the command fails outright: netbird status -d Error: status failed: grpc: received message larger than max (4287609 vs. 4194304) The limit is raised where the daemon dial options are built, so every caller inherits it: the CLI, the desktop UI, the JSON gateway, and the SSH client and proxy. It is overridable through NB_DAEMON_GRPC_MAX_MSG_SIZE for a deployment that outgrows the new default too, mirroring what the management client already does with NB_MANAGEMENT_GRPC_MAX_MSG_SIZE, and reusing its 16 MB default. Only the receive direction needs raising. Requests to the daemon are small, and gRPC does not cap the send side by default, so the daemon could already send a response the caller then refused to read. |

[misc, android] Build and lint the mobile Go code in CI (#7641)
Nothing in CI compiles the files behind //go:build android or //go:build ios. The android bridge builds 7 of its 23 files on linux and skips client.go; the iOS SDK is not built at all. The linter matrix picks a GOOS by picking a runner OS, so it loads the same file set as the host build and never sees them either. A type error in client/android/client.go therefore passes every check on its PR, merges, and is discovered by netbirdio/android-client after sync-tag.yml fires trigger_android_bump on the release tag. The new Mobile workflow cross-compiles ./client/android/... for the GOARCH values gomobile ships and ./client/ios/..., and vets the android bridge. The new Android and iOS lint jobs run golangci-lint with GOOS/GOARCH in the job env. No NDK, Xcode or gomobile is needed: these are library packages, so the compiler type-checks them without a link step, and the dependency graph drags in the android/ios-tagged files across client/iface, client/internal/dns and client/internal/routemanager with them. Linting those files for the first time surfaces one gosec G101 on the SSH password-required marker. It is a sentinel string the Java side matches on, not a credential, so it is suppressed at the declaration. |

[client] Validate the saved service parameters and pin the netsh lookup (#7584)
* [client] Export the only-owner-writable path check from elevate
Pure refactor, no behavior change: the existing checkOnlyOwnerWritable gets a
thin exported wrapper so callers outside the elevation path can reuse it. No
call site changes here.
* [client] Validate the saved service parameters before applying them
The install reads <stateDir>/service.json and applies it to the service it then
registers: its arguments, its config path and its environment. The restricted
ACL that saveServiceParams puts on the state directory is applied when the file
is written, which is not necessarily before the file is first read, so the
install now checks the file rather than assuming it.
A file whose ownership or permissions are not the ones saveServiceParams
produces is treated as absent, and the install proceeds with its defaults. The
check covers the directories above the file as well, so what is checked is what
is read.
* [client] Restrict which environment variables the service is registered with
--service-env, and the service.json it persists to, accepted any name. A small
set of them decides how a process resolves the executables and libraries it
loads, and the daemon needs none of those: it now refuses them when they are
passed explicitly, and drops them with a warning when they come back from a
service.json written by an older version, so an upgrade does not fail over a
variable nobody needs.
* [client] Resolve netsh by absolute path
The lookup consulted PATH first and fell back to System32, in both the copy the
userspace firewall uses and the one that tears the interface down. It now asks
Windows for the system directory, so the resolution no longer depends on the
environment the service happens to be started with.
* [client] Move the System32 lookup into a package both callers share
Pure refactor, no behavior change: client/iface and client/firewall/uspfilter
carried a copy each of the same function, and neither imports the other, so the
body moves to client/internal/wincmd — alongside winregistry, which is where
the client's other Windows-only helper already lives. Both call sites now read
wincmd.System32("netsh").
* [client] Cover the System32 lookup with a test
Asserts what the previous commits changed: the lookup is absolute, and neither
PATH nor %SystemRoot% moves it.
* [client] Refuse the loader environment families by prefix
Review follow-up on the previous commit:
- LD_* and DYLD_* are now refused whole rather than name by name. Their members
differ per platform and libc and grow with new OS releases, so a list of them
is out of date as soon as it is written — DYLD_FALLBACK_LIBRARY_PATH and
DYLD_FALLBACK_FRAMEWORK_PATH were already missing from it.
- The names are folded to upper case only on Windows, where a variable is the
same one however it is spelled. Elsewhere the environment is case-sensitive,
so Path and PATH are two variables and only the exact spelling is the one that
is read; the fold refused the wrong one.
- TEMP and TMP stay in the denylist, but the rationale and the message now say
what they actually decide: where the service writes, not what it loads.

[client,management] Skip route firewall rule computation when no firewall (#7624)
* [client,management] Skip route firewall rule computation when no firewall A peer that runs with the firewall disabled has no ACL manager and no firewall to program, so nothing ever reads RoutesFirewallRules: the only consumers are acl.Manager, which is reached solely when e.acl is set, and the legacy-management probe in updateNetworkMap, which is guarded by a non-nil firewall. Building those rules is the most expensive part of a sync on a peer that routes many network resources. On a 15k-peer deployment a debug bundle showed getPeerNetworkResourceFirewallRules accounting for 62% of the allocations of Calculate, and Calculate for effectively all of the allocations of handleSync, which was taking 3.2s on average and holding the engine lock for the duration. Let the caller ask Calculate to leave the rules out. The client passes its existing DisableFirewall setting; the management server keeps the default and still produces them. RoutesFirewallRulesIsEmpty is set from the resulting empty list, so a receiver that would otherwise infer legacy management from an empty rule set does not misread the skip. * [client,management] Cover the skip flag through the envelope Review feedback on #7624. The components test compared only the length of the peer firewall rules, so a change to their content would have passed while the message claimed they came out unchanged. Compare the slices. The skip path was also only exercised by setting the field directly on the components, which bypasses the envelope conversion where RoutesFirewallRulesIsEmpty is derived. That bit is what keeps the client from reading skipped rules as a legacy management server, so it gets a test that goes through EnvelopeToNetworkMap with the flag set. * [management] Give the router a peer ACL so the rule comparison bites Review feedback on #7624. peer-router-1 appears in no peer ACL in the shared fixture, so its FirewallRules came out empty and the equality assertion compared two empty slices — it would have passed even if the peer rules were dropped entirely. Add a policy covering the router and require the baseline to be non-empty before comparing. |

[client] Fix peers not being notified when the relay connection drops (#7490)
* [relay] Signal relay disconnects through the conn context AddCloseListener deduplicated listeners by comparing reflect.ValueOf(callback).Pointer(). For a method value that pointer is the address of the compiler-generated wrapper, not an identity bound to the receiver, so every peer's w.onRelayClientDisconnected compared equal. All peers on the home relay register under the same connectionURL key, so only the first registration survived and the rest were silently dropped. On a relay disconnect those peers were never notified: statusRelay stayed connected and the reconnect guard never fired. The relayed net.Conn itself was closed by closeAllConns, so nothing leaked, but the peer state machine did not learn about it. Foreign relays had the same defect scoped to the peers sharing that server. Rather than fixing the deduplication, drop the peer-level listener registry entirely. A relayed Conn now exposes Context(), cancelled when the connection is torn down, with a cancellation cause naming the reason. This is the same shape quic-go uses for its Conn and Stream types, and it removes the whole class of problems around listener identity, lifetime and deregistration: the signal belongs to the resource instead of a side table. WorkerRelay watches that context in a goroutine whose lifetime matches the connection. A watcher that wakes up for a superseded connection compares the conn pointer against the current one and returns without touching the state machine, so a fast relay reconnect cannot have a stale watcher tear down the connection that replaced it. Client.SetOnDisconnectListener stays: it is server-level and drives the reconnect guard and foreign relay eviction, unrelated to peers. handleRelayReady also checks the conn context, closing the race where the relay dies between OpenConn and the readiness handoff and the peer would otherwise build a WireGuard endpoint over a dead connection. TestNotifierDoubleAdd covered the removed mechanism and is gone. TestForeignAutoClose asserted nothing (both branches logged); it now waits for the relay to leave the client map and fails if it does not. * [relay] Fix build: return the concrete conn from Client.OpenConn OpenConn now returns *Conn, but it still went through connContainer.netConn(), which widens to net.Conn. The helper had one caller and only existed to produce the interface value the signature no longer wants, so return container.conn directly and drop it. * [relay] Assert the local-close cancellation cause explicitly The local-close test only rejected ErrServerDisconnected, so it would also have passed for ErrPeerDisconnected or a bare context.Canceled. closeConn cancels with net.ErrClosed, so assert that. * [client] Ignore relay disconnects from superseded connections The relayed conn watcher compared the conn pointer under relayLock, released it, and only then tore the connection down. A new offer could install its replacement in that window, so a watcher that validated the old pointer went on to close the proxy of the connection that had already replaced it and report the peer as disconnected while it was up. Move the decision to where the teardown happens. Conn records which relayed connection the current proxy was built from, and onRelayDisconnected takes the connection the signal belongs to and drops it under conn.mu when it is no longer the current one. Check and effect are now in the same critical section, so the verdict cannot go stale before it is acted on. This also covers the proxy read loops, whose disconnect listener took no argument and had the same defect: it now names the connection it belongs to. The WG timeout path keeps passing nil, since it deliberately tears down whatever is current. * [client] Bind the relayed conn reference to the proxy swap relayedConnRef was set at the top of the readiness path, but wgProxyRelay only changes at the end, in setRelayedProxy. The two failure returns in between — newProxy and ConfigureWGEndpoint — left the reference pointing at a connection that never became active while the old proxy was still installed. A disconnect of that old, live relay would then be dismissed as belonging to a superseded connection and never cleaned up. Set the reference in setRelayedProxy, next to the proxy it belongs to. Both success paths go through it and neither failure path does, so no failure branch has to remember to roll anything back. |

Read the session deadline under the status read lock (#7550)
GetSessionExpiresAt took the exclusive lock for a plain field read, so every caller queued behind writers and behind each other. The Android SessionMonitor polls it from the main thread, and in the captured ANR that is exactly where the main thread was blocked while hundreds of peer-list callbacks held or waited on the same mutex. d.mux is already an RWMutex and the other getters use RLock; this brings the deadline read in line with them. |

[client] Fix the Windows tray deadlock on re-entrant window creation (#7449)
* [client] Fix the Windows tray deadlock on re-entrant window creation The Wails systray runs the left-click handler synchronously inside the tray window procedure, and creating a window on a running app pumps a nested Win32 message loop while WebView2 initialises. ensureWindow held the non-reentrant createMu across that creation, so the second button-up of a double click re-entered ShowWindow from the pump and blocked the main thread on its own lock. A goroutine holding createMu while the main thread pumped, and the Open* dialogs holding mu across NewWithOptions, Show, Hide and InvokeSync, exposed the same inversion. WindowManager now serialises creation with a per-slot creating flag and queues the callers' operations until the window exists, and no Wails call runs while mu is held. The tray click and second-instance handlers call ShowWindow off the message loop. * [client] Serialize window operations while a slot is being created Callers arriving after the window is published but before the creator has drained the queue took the existing-window fast path and could run ahead of older queued operations, so a newer SetURL could be overwritten by an older one. withWindow now queues every caller while the creating flag is set and clears the flag only once the queue is seen empty under the lock. A factory panic or a nil window left the creating flag set and the slot dead; creation and drain now reset that state on early exit. hideOtherWindows records the windows it hid only when no restore ran in between, tracked by a generation counter, and re-shows them otherwise, so a restore racing the hide cannot strand hidden windows. * [misc] Run the client/ui subpackage tests in CI The three test workflows filtered the package list with a `/client/ui` prefix match, which dropped the subpackages along with the package that cannot compile without a frontend build. `services`, `preferences`, `i18n` and `authsession` all carry Go-side unit tests that never ran, including the window manager re-entrancy regression test. Anchor the pattern so only `client/ui` itself is excluded. The linux leg keeps the prefix match on 386, where only the 64-bit gtk4/webkitgtk dev packages are installed and the Wails application package would fail to link, and the alpine container job keeps it for the same reason. * [misc] Run the client/ui subpackage tests on a gtk4 4.10 runner The previous commit let the subpackages into the linux client job, where client/ui/services failed to build: the wails runtime's linux cgo layer uses GtkFileDialog, which arrived in gtk4 4.10, and the job's ubuntu-22.04 runner ships 4.6. Move them to their own job pinned to ubuntu-24.04 and restore the linux client job's original exclusion, leaving the 386 and privileged legs on the runner they have used since 2024. The new job needs no build cache, sudo or privileged tag, so it stays a few seconds long. Darwin and Windows keep the anchored pattern from the previous commit and already run these tests green, including the window manager re-entrancy regression test on the platform the deadlock was reported on. * [client] Defer a window close that lands while the window is still being created WindowManager publishes a dialog's slot only after the factory returns, and on Windows the factory blocks in the WebView2 embed pump. A Close* arriving in that gap found a nil slot and returned without doing anything, so the dialog appeared afterwards for a flow that had already been cancelled. The pre-fix Open* dialog functions held mu across the whole creation, which blocked a concurrent Close* until the slot was set; removing that lock hold reopened this gap. Close* now goes through closeWindow: while the slot is being created it records a closer in pendingClose, and finishCreation runs that closer before any queued operation, so a window that is going away is never shown and Wails never sees a Show on a destroyed window, which would recreate it. Ops queued behind a close are dropped; windowOp carries no factory, so they cannot be replayed into a new creation, and the frontend callers reissue on the next state change. The browser-login slot uses the same restoring closer from both CloseBrowserLogin and CloseRenewFlow, since the popup's WindowClosing hook only restores on a user close. Where two closers race one creation the first registered wins, so a later caller cannot replace a restoring closer with one that does not restore. |

[client, proxy] Make the buffer-pool retune reachable while a device is stalled (#7452)
* [client] Track the WireGuard device on the engine as a lock-free handle Add an atomic handle on the wg device next to wgInterface, stored once the interface is up and cleared when it is closed. Nothing reads it yet, so this is a pure addition with no behavior change; it exists so the next commit can reach the device without taking syncMsgMux. * [client] Retune the WireGuard buffer pool without the engine lock SetPerformance took syncMsgMux before reaching the device. That lock is held by handleSync while it adds and removes peers, and peer removal is exactly what blocks when a device's buffer pool is exhausted: Peer.Stop waits on a keepalive timer callback that is itself parked in WaitPool.Get. Raising the cap is the way out of that state, so the call must not queue behind the lock the stall is holding. Read the device through the atomic handle instead. Device.SetPreallocatedBuffersPerPool takes the pool's own lock and broadcasts, so the waiters wake up. * [proxy] Extract the buffer-cap apply loop out of the perf handler Pure move: the loop over the registered clients becomes applyBufferCap, with the same sequential behavior and the same return values. Split out so the next commit can change how it iterates without the diff also carrying the move. * [proxy] Bound the perf endpoint so one wedged client cannot hold it The apply loop was sequential and unbounded. embed.Client.SetPerformance goes through the client lock, which Start holds for the whole of a startup, so a single account that is busy or wedged delayed the new buffer cap for every other account on the node -- on the endpoint whose whole purpose is to un-wedge a node. Apply to all clients concurrently and give the whole call a 5s budget. Accounts that do not answer in time are reported in "failed" instead of blocking the response. * [client] Drop the device handle before closing the interface close() cleared the atomic handle only after wgInterface.Close() returned, so a concurrent SetPerformance could still load it, retune a device that is being torn down, and report the change as applied for an engine that has stopped. Clear it first, so the window closes before the teardown begins. Reported by cubic on PR #7452. * [proxy] Put the per-client retune behind a field Pure refactor: applyBufferCap calls h.setPerformance instead of the client method directly, and NewHandler wires it to setClientPerformance. Same call, same behavior; the seam is what lets the next two commits be tested without a live embedded client. * [proxy] Do not report a finished retune as timed out When the deadline fires, select chooses at random among the ready cases, so a result already sitting in the buffered channel could be skipped and its account reported as timed out even though the cap had been applied. Drain what is buffered before declaring the rest pending. Reported by cubic on PR #7452. * [proxy] Keep one retune per account in flight The 5s budget bounds how long the endpoint waits, not the work: SetPerformance goes through the embedded client's lock, and on a wedged account Stop holds that lock forever, so every retry left one more goroutine parked there. Route each account through a single worker. A request that finds one already running takes its result if it has landed, and otherwise reports the account under "in_flight" instead of starting a second attempt. One stuck account now costs one goroutine, no matter how often the endpoint is called. Reported by CodeRabbit and cubic on PR #7452. * [proxy] Make the retune budget a var Pure refactor: perfApplyTimeout becomes a var so a test can shorten it instead of waiting five seconds. Same value, same behavior in production. * [proxy] Extract the buffered-result drain Pure refactor: the loop that empties the results channel when the deadline fires becomes collectBuffered. Same behavior; split out so it can be tested on its own, which the inline version could not be without racing the deadline. * [proxy] Cover the retune single-flight and the deadline drain TestApplyBufferCapSingleFlightPerAccount fails without the worker registry: five calls against a client stuck in its own lock start five blocked workers instead of one. TestCollectBufferedCountsResultsReadyAtTheDeadline pins the drain helper's contract - buffered results counted, errors recorded, only unanswered accounts left pending. It drives collectBuffered directly: through applyBufferCap the two select cases race by construction, so an end-to-end version of it would pass on the unfixed code about half the time. * [proxy] Keep the worker alongside each pending account Pure refactor: the pending set becomes a map to the account's worker instead of an empty struct. Same membership and same behavior; the next commit needs the worker to resolve an account whose result has not reached the channel yet. * [proxy] Publish a retune result before releasing its slot The worker sent its result last, after taking perfMu to remove itself from the registry. That lock is taken once per account by every caller walking the fleet, so a worker that finished on time could queue behind an apply over thousands of accounts and land after the deadline. Send first, deregister after. Reported by cubic on PR #7452. * [proxy] Read the worker, not the clock, for a finished retune Publishing earlier only narrows the window: a client that answers just before the deadline can still be reported as timed out. At the deadline the workers themselves are authoritative - a closed done channel means the retune finished and w.err carries its outcome, ordered by the close. Consult them instead of declaring every pending account timed out, and keep the timeout label for the ones actually still running. Reported by cubic on PR #7452. * [proxy] Cover the finished-worker resolution at the deadline Fails on the previous behavior with "applied = 0, want 1": every pending account was labelled a timeout, including the one whose retune had already completed. |

[client] Compare MDM-managed URLs as endpoints, not as strings (#7472)
A policy that enforces a management URL refuses any SetConfig or Login whose URL differs from it. The comparison normalized only the default port, so three ways of writing the very endpoint the policy names were reported as conflicts: policy https://mgmt.example.com vs https://mgmt.example.com/ refused https://MGMT.example.com refused https://mgmt.example.com:0443 refused For an MDM-managed deployment whose stored or command-line URL is spelled differently from the policy's value, that means every settings update is refused with an MDMManagedFieldsViolation naming a field the caller did not change. `netbird up --management-url https://MGMT.example.com` reproduces it. The rules now live in util.SameServiceURL, and ConflictURL delegates: scheme and host compared case-insensitively, the effective port normalized numerically, a trailing slash ignored, and a path otherwise still part of the identity so /other remains a divergence. Unparseable input falls back to string equality. util rather than either caller, because comparing two service URLs is neither device management nor profile storage, and more than one place does it: an MDM-enforced management URL against a requested one here, a stored profile URL against a command-line one in profilemanager and the SSH gate. Every copy of these rules that drifts turns an equivalent URL into a refused request, which is how this one arose. CanonicalURL is left alone: besides comparison it is the canonical value handed to mdm.Restrictions and to the Android and iOS Preferences getters, and normalizing what those return is a separate decision. |

[client] Read MDM boolean keys delivered as JSON numbers (#7471)
encoding/json decodes every JSON number into float64, so the policy values the mobile loaders produce never contain int or int64. GetBool accepted both of those but not float64, so a managed boolean pushed as 1 or 0 — how some MDM consoles normalise flags — was reported as unreadable while the key still counted as managed: the policy was not applied, and the conflict gate rejected both values the user could pick for that field. The rejected-float assertion predates the JSON channel. It came with the registry and plist loaders, where a real number for a flag is a configuration mistake; on the JSON channel an integer is the only shape a number can take. GetInt already accepts float64. |

[client] mobile MDM bridge — iOS + Android setMDMPolicyFetcher entrypoint (#6435)
* MDM Android mobile wiring * Removes dead code * Removes static vars * Now we need to apply MDM in the GetConfig * You now need to explicitly call these around * Adds iOS wiring * Resolve merge conflicts from main - login.go: keep both new imports (mdm + nbnet + server) - ios/NetBirdSDK/client.go: additive struct-field merge (mdmLoader + stateMu/connectClient/config) - setconfig_mdm_test.go: adopt new withMDMPolicy(t, s, policy) signature; fix stray old-signature call in TestSetConfig_MDMAllow_ManagementURLPortNormalized * Convey MDM overlay config to Debug Bundle output Aligns to other clients OSes behavior * Solved conflict in client.go * Fixup helper withMDMPolicy -> configWithMDM * Fixup after merge * Resolve merge conflicts * [client] Move MDM enforcement logic into a shared Go layer (#7319) The mobile bridges only carried the policy fetcher, leaving every enforcement decision to the native apps: the desktop derived its UI restrictions in the Wails service layer, the daemon kept the conflict machinery in the server package, and both mobile bridges duplicated the JSON fetch adapter. Anything the native side had to reimplement was a place for iOS and Android to drift apart. Enforcement now lives in client/mdm and is consumed identically by all three platforms: - conflicts.go holds the value-aware conflict checks lifted out of the daemon, so the same normalization (canonical URLs, PSK sentinel echo) applies wherever a config change is validated. - restrictions.go derives the UI enforcement snapshot from a policy and renders it in the JSON shape the desktop frontend already consumes. The service-layer types become aliases, keeping one source of truth. - jsonloader.go replaces the adapter that was copy-pasted into both bridges. - changedetector.go moves change detection off the native side: the caller forwards the OS notification and asks whether the managed configuration actually changed, instead of diffing dictionaries itself. The mobile bridges gain the enforcement the daemon already had. The Preferences getters resolve managed keys from the policy, so a naive UI shows the enforced value; Commit rejects a staged change that diverges from a managed key; NewAuth resolves the managed management URL before persisting the config and overlays the policy on it, so a login can no longer run against a URL the policy forbids. Android's profile mutations fail closed when disableProfiles is set. NewAuth takes the fetcher as a required argument rather than keeping a policy-blind overload: the apps consume this code as a submodule, so a compile error at the bump is the point. The mobile PSK getter is replaced by a presence check — the key has no reason to cross the bridge, and not returning it means the native side needs no redaction sentinel of its own. * [client] Resolve the main merge conflicts in the MDM integration The merge commit was recorded with the conflict markers still in the tree. Resolve them so the branch builds again: - client/ios/NetBirdSDK: keep both the mdm and mobile imports, and keep the mdmLoader/mdmDetector fields next to main's stateMu documentation. - client/server/mdm.go: drop the conflict helpers main added locally, they already live in the client/mdm package on this branch, and keep the new checks main introduced (allowRemoteJobs, enableLocalMetrics, localMetricsAddress) as calls into the package-level helpers. - client/mdm/conflicts.go: add ConflictStringPtr, the presence-aware string check main needs for the optional localMetricsAddress field. - Port the two tests main added over the per-Server loader helper and the configWithMDM helper, both of which replaced the package-level policy injection this branch removed. * [client] Reject explicit empty PSK when MDM enforces a pre-shared key The SetConfig, Login and mobile Commit conflict checks collapsed the PSK to a plain string, so an explicit empty value was indistinguishable from an unset field and slipped past the MDM gate, clearing the persisted key. Carry the optional field as a pointer through ConflictStringPtr, treating only the redaction sentinel as a no-op echo. ConflictString had no other callers and is removed. * [client] Apply MDM overlay on the preloaded iOS config in Run Run only overlaid the MDM policy when the config was loaded from file, so the tvOS path fed by SetConfigFromJSON started with unmanaged settings. Apply the overlay after the config source is selected, as the other resolution sites already do. * [client] Gate non-active profile logout behind the MDM profiles switch The mobile ProfileManager let LogoutProfile clear credentials of any profile even when disableProfiles was enforced. Follow the daemon's validateProfileLogout semantics: logging out of the active profile is a plain logout and stays allowed, logging out of any other profile is profile management and is rejected under the policy. * [client] Resolve the managed management URL through the MDM overlay on mobile NewAuth on Android and iOS replaced the caller URL with the raw policy value before persisting, so a malformed managed URL failed config validation and blocked the login instead of being skipped with a warning like the overlay does. Preferences.GetManagementURL likewise echoed the raw policy string to the native UI even when the overlay had rejected it. Follow the daemon: persist the caller URL, overlay the policy on the resolved config, and report the overlaid ManagementURL as the effective value. * [client] Clean up MDM review leftovers Drop the unused ChangeDetector.Current, point the stale LoadPolicy comment references at Loader.Load, and move the profileEmail godoc back above its function. * [client] Check remote jobs and local metrics keys in the mobile MDM conflict gate MDMConflicts skipped allowRemoteJobs, enableLocalMetrics and localMetricsAddress even though the overlay applies all three and the daemon gate already checks them, so a mobile Commit could persist values diverging from the enforced policy. Align the list with the daemon. * [client] Silence the deprecated PreSharedKey lint in the login conflict test The legacy LoginRequest.PreSharedKey field is deliberately exercised by the test, matching the nolint already carried by the production path. * [client] Publish the mobile MDM loader and detector atomically SetMDMPolicyFetcher wrote the loader and change detector as two plain fields that Run, the OS-change callback and the restrictions getter read from other threads without synchronization. Hold both behind a single atomic pointer so a registration is published as one unit and readers always observe a matching loader and detector pair; Preferences gets the same treatment for its loader. Exported signatures are unchanged. * [client] Report the MDM-overlaid remote jobs value from mobile Preferences GetRemoteJobsAllowed returned the staged or persisted value even when the policy manages allowRemoteJobs, so the native settings UI could show a value the Commit gate would reject. Resolve it through the overlay like GetManagementURL does. * [client] Stop persisting the MDM-overlaid config after mobile logins NewAuth already writes the config through UpdateOrCreateConfig before the MDM policy is overlaid, and the login itself never mutates the Config. The post-login WriteOutConfig calls therefore only rewrote the same file with the enforced ManagementURL and PreSharedKey in it, so a removed or changed policy kept acting through the persisted values. * [client] Document that the MDM overlay on Config is not reversible ApplyMDMPolicy promised that an empty Policy clears a prior overlay, but applyMDMPolicy only resets the enforcement metadata and the runtime-only upload URL; the enforced ManagementURL, PreSharedKey and flags stay. Every lifecycle owner resolves the base Config again before applying, so state that contract instead of the reversibility that was never implemented. * [client] Re-resolve the tvOS preloaded config before every MDM overlay The iOS Client kept the config parsed from SetConfigFromJSON and applied the MDM overlay onto that same instance on every Run, IsLoginRequired and DebugBundle, so a key removed from the policy stayed enforced. Store the JSON instead and parse it per load through one loadConfig path. Auth serialized the overlaid config from GetConfigJSON, which tvOS then persisted to UserDefaults and fed back as the preload. Keep the resolved config as the base, run the login on a JSON round-trip copy with the overlay, and return the base from GetConfigJSON. * [client] Serve the MDM-managed management URL without touching the config file on mobile Preferences.GetManagementURL resolved a managed URL by reading and overlaying the persisted config, so a corrupt file or the tvOS sandbox turned an enforced URL into a read error. Return the canonical managed value directly, the same string BuildRestrictions already hands to the UI, and only fall back to the staged or persisted value when MDM does not manage the key. NewAuth validated the caller-supplied management URL before the overlay ran, so a malformed or echoed value blocked or persisted under an MDM policy that already dictates the URL. Ignore the caller value while the key is managed; the login runs against the overlay either way. * [client] Align the MDM loader docs with the fetcher precedence and make disableAdvancedView a tristate NewLoader, PolicyFetcher and the darwin/windows loadPlatform docs claimed the fetcher is unused on desktop, while every loader returns its values when one is injected. That precedence is the seam the server tests rely on across platforms, so the docs now describe it; production desktop callers still pass nil and keep the registry / plist authoritative. Fields.DisableAdvancedView collapsed "managed and false" into the same JSON as "not managed", unlike AllowServerSSH and the daemon's optional proto field. Carry it as a *bool so the UIs can tell the two apart; the desktop reflect loop skips pointer fields already, and the mobile decoders treat null as not managed. * [client] Clean up MDM review nits - ResolveConflicts treats a managed key whose ConflictCheck has no Check as a conflict instead of dereferencing nil. - Ticker.Run and ChangeDetector.Changed share policyChanged so the diff semantics and the log line cannot drift apart. - TestLoader_NilFetcherReturnsEmpty skips on windows/darwin, where a nil fetcher reads the real registry / plist. - The profilemanager test loader checks GetInt before GetBool so integer keys survive the round trip, and the PSK tests use the exported redaction sentinel. * [client] Fix int policy values coercing to bool in the MDM test helper withMDMPolicy rebuilt the policy map by trying GetString, then GetBool, then GetInt. Policy.GetBool accepts native ints (non-zero means true), so an int-valued key such as wireguardPort round-tripped through the helper as the bool true and GetInt was never reached. Try GetInt before GetBool, as the profilemanager helper already does; GetInt does not coerce bools, so booleans still fall through to GetBool. No test sets an int key today, so this was latent: the first test to exercise the wireguardPort conflict gate would have seen ConflictInt64 report a conflict for every value, including a matching one. --------- Co-authored-by: Zoltan Papp <zoltan.pmail@gmail.com> |

[client] Return the context error when the SSH handshake fails with it (#7426)
* [client] Return the context error when the SSH handshake fails on a context deadline The handshake mapped the context deadline onto the socket but returned the raw socket error. Which error surfaces depends on a race between the x/crypto ssh readLoop and kexLoop goroutines: the kexLoop write fails with i/o timeout and closes the conn, and the readLoop then reports use of closed network connection. Callers checking errors.Is(err, context.DeadlineExceeded) never matched, and TestSSHClient_ContextCancellation flaked on the FreeBSD job. Handshake now wraps the context error when the context is done or its deadline has passed. The deadline comparison is needed because the socket deadline and the context timer fire independently, so ctx.Err() can still be nil when the deadline-triggered socket error arrives. * [client] Close the silent test server conn without racing t.Cleanup The accept goroutine registered the conn close via t.Cleanup, which can run after the test's cleanup list has already been drained, leaving the accepted connection open. The goroutine now holds the conn until a cleanup-closed channel signals the end of the test and closes it on the way out. * [client] Bind the SSH handshake to the context instead of a socket deadline Mapping only the context deadline onto the socket left context cancellation unobserved: an in-flight handshake kept running until the deadline, and the error classification had to guess whether a raw socket error was caused by the deadline. Closing the conn from context.AfterFunc covers both deadline and cancellation, and ctx.Err() is already set by the time the close-induced error surfaces, so the time-based DeadlineExceeded attribution is no longer needed. The stop() result guards the window between a successful handshake and the AfterFunc firing so a closed conn is never handed back as a client. |

[management] Add Agent Network managed proxy to the API spec (#7433)
Defines the cloud-side managed gateway provisioning surface (POST/GET /api/integrations/agent-network/managed-proxy) and its response objects so clients consume generated types instead of hand-written ones. POST is idempotent: 202 when the call starts (or restarts) provisioning, 200 when a deployment already exists; 409 names an already-assigned endpoint the managed flow does not own and 503 signals temporarily exhausted endpoint allocation. |

[client] Assign the Android TUN address as a host prefix (#7414)
Android 16+ local network protection derives the blocked prefixes from the interface address prefix. A /16 address turns the whole overlay into a local network, so apps without ACCESS_LOCAL_NETWORK cannot reach any peer. Pass the address as /32 and /128 and add the overlay networks to the route list that the Android side turns into VPN routes, on both the initial create and the renew path. |

[client] Gather fresh system info on every management sync stream connect (#7409)
* Gather fresh system info on every management sync stream connect The engine collected the peer meta once at start and reused the same Info for every Sync stream reconnect, so a mobile network switch that redials management kept reporting the old local network addresses. The peer network range posture check was then evaluated against stale data until the client restarted. Sync now takes a gatherer that runs at each stream connect. The gatherer is cheap: GetInfo plus the cached posture check file results, kept in the new system.InfoSource, which the engine refreshes whenever the checks list changes. No process enumeration runs on the reconnect path. Also fix the management mock server calling itself instead of SyncFunc. * Evaluate the login response posture checks before the first sync connect The engine starts with the checks the login response carried, and the first sync stream request used to send their evaluated file results. After moving the gather into InfoSource, the stream opened with an empty cache and the first sync response did not refill it, because its checks equal the ones the engine already holds. Desktop peers therefore never reported process or file posture results. Seed the cache once before the first connect, where the old gather ran, so a timed out evaluation still falls through to the address-only info. * Harden the sync info source against nil callbacks and shared slices A nil getInfo opens the stream without metadata, as a nil sysInfo did before. The cached posture results are a copy, so the Info returned by Refresh cannot alias the snapshot later Current calls report. The exclusion test asserts the remaining address count so it cannot pass vacuously on a single-address host. * Retry a posture check refresh that timed out or failed to sync The checks list was recorded before the gather ran, so once the gather timed out or SyncMeta failed, the next sync response carrying the same list matched the recorded one and nothing retried. The peer kept reporting the previous posture results until the list changed again. Record the checks only after the meta reached management, so a failed cycle is repeated on the next sync response. * Log the skipped posture refresh, let the mock Sync return errors and deflake the reconnect test * Drop the nil guard around the sync info callback * Send the refreshed info on the first sync connect instead of gathering it twice |

[client] Expose the remote jobs opt-in in the Android and iOS SDK preferences (#7406)
Remote jobs (debug bundle requests from management) are gated behind Config.RemoteJobsAllowed, which defaults to false and could only be enabled through the CLI flag or an MDM policy. The mobile SDKs had no way to set it, so the mobile clients always refused the job. Add GetRemoteJobsAllowed/SetRemoteJobsAllowed to both mobile Preferences types, following the existing ServerSSHAllowed accessors, so the apps can offer a settings toggle for it. |
