010f5281ce Removes confirm. Uses next offer to deliver confirmation/ack of previous round
We clock the next Offer initiation to the OnDataPathRekeyed, so we have 2 minutes
ahead of us to do our attempts and stuff before to give up.
On failure, we will know because we will not receive a new answer.. but more importantly
the wg handshake will fail :D

7d2c71f84f Assume two transports: initial "signal" (control plane) one (no data path established yet) + data path one
Define OnDataPathRekeyed event to transition from control plane path to data plane path over the WG tunnel.

Keep confirm ALWAYS on NEW established WG tunnel (posthandshake with rekeying). We keep an active method
irrelevant of the WG handshake (we might decide that the indirect wg handshake is sufficient in the future).

Optimistic commit on responder(when sending answer), while on initiator we set it on getting the answer

46568f7af8 [client] Reconcile routed allowed IPs when a lazy connection goes idle (#6863)
## Describe your changes

Under lazy connections, when a routing peer goes idle its WireGuard peer
is torn down and re-created with a wake endpoint by
the activity listener, carrying only the overlay /32
(`peerCfg.AllowedIPs`). The routed subnet prefixes are dropped from
  the device on the Connected→Idle transition.

They are meant to be restored by the route watcher, which reacts to the
peer's status change and calls `recalculateRoutes` →
  `AddAllowedIP`. Two things prevent that from healing the peer:

- `AddAllowedIP` uses `update_only`, which is a silent no-op (no error)
when the peer does not exist. While the peer is
being torn down and re-armed with its wake endpoint, it is briefly
absent, so a re-add that lands in that window is lost.
- The allowed-IP refcounter only calls its add function on a prefix's
0→1 transition. The routed prefix stays referenced
across the idle cycle, so once the device entry is gone the refcounter
does not re-push it on its own, and nothing retries.

As a result, traffic to the routed subnet is black-holed while the peer
is idle. Because the wake endpoint only fires when a
packet matches the peer's AllowedIPs, a packet to the subnet is dropped
before reaching the wake endpoint, so it cannot
wake the peer. The peer only recovers when woken by other means (e.g. a
ping to its overlay IP).

  ## Approach

This change keeps the existing Connected→Idle transition as-is and
reconciles the AllowedIPs afterwards, avoiding any
additional locking on the transition path. The peer is torn down and
re-armed with its wake endpoint as today; the routed
prefixes are then re-applied from the route manager's allowed-IP
refcounter once the wake endpoint has been (re)armed.

A single add-only method, `ReconcilePeerAllowedIPs(peerKey)`, re-applies
every routed prefix currently tracked for the peer
in the refcounter (the authoritative store; it already covers static,
dynamic and dnsinterceptor routes). It runs whenever
the peer's wake endpoint is (re)created in the lazy manager — every
point where the activity listener builds it with the
  overlay /32 only:

- **initial registration** (`AddPeer`, cold start): the route manager
may have already pushed the peer's routes before the
wake endpoint existed, so those `AddAllowedIP` calls no-op'd; the
reconcile installs them on the freshly created wake
  endpoint.
- **the two paths into idle** (`DeactivatePeer` on a remote GOAWAY,
`onPeerInactivityTimedOut` on local inactivity): the
peer is torn down and re-armed, so the routed prefixes must be
re-applied.

In every case the routed prefixes end up on the wake endpoint, so
traffic to a routed subnet can wake the peer. Arming the
wake endpoint and reconciling are wrapped in a single
`armActivityListener` helper so the two always happen together.

New helper: `refcounter.Counter.KeysMatching(pred)` to enumerate a
peer's prefixes under the counter lock.

Note on scope: the reconcile restores what the refcounter tracks. All
routed AllowedIPs currently go through it, so this
covers the routed-prefix case; it does not attempt to reconcile
AllowedIPs installed outside the refcounter. The
Idle→Connected (wake) path does not need this: the peer is not removed
there (the listener close leaves it in place and only
the endpoint is updated), so a concurrent `AddAllowedIP` lands normally.

  ## Testing

Reproduced deterministically in a local dev setup (userspace client,
`NB_WG_KERNEL_DISABLED=true`, `B_LAZY_CONN_INACTIVITY_THRESHOLD=1`
inactivity threshold 1
min). A temporary 30s sleep in the tear-down → re-arm window widens the
race so the route watcher's async `AddAllowedIP`
reliably lands while the peer is absent and no-ops (the sleep is a test
aid, not part of the change):

- **without the reconcile:** after the peer goes idle, a ping to any
routed IP — both a pre-existing route and one added
  during the window — black-holes; the peer never wakes.
  - **with the reconcile:** the same ping wakes the peer and passes.

Added unit tests: `ReconcilePeerAllowedIPs` (re-applies all of a peer's
tracked prefixes, scoped to that peer) and
  `refcounter.Counter.KeysMatching`.

Note: `netbird status -d` is not a reliable signal for this —
`AddPeerStateRoute` records the route regardless of whether
the underlying `AddAllowedIP` no-op'd, so it reflects the route
manager's intent rather than device state. The reliable
  signal is functional (ping the subnet from idle).

## Summary by CodeRabbit

* **Bug Fixes**
* Routed IP assignments are automatically reconciled and restored
whenever a peer’s lazy wake endpoint is armed or re-armed.
* Routed allowed IPs are re-applied after inactivity transitions and
monitoring re-initialization.
* If reconciliation can’t be performed, the client safely skips it; if
reconciliation encounters issues, failures are logged without stopping
connection monitoring.

9770814f39 [client] warm lazy connections from the DNS resolver (#6854)
## Describe your changes

Supersedes #6767 (same change, moved to an unprefixed branch; review
feedback from there is addressed here).

With lazy connections enabled, a peer is not dialed until on-demand
traffic arrives, so the first request to a peer resolved by name (e.g.
the agent-network reverse-proxy) races — or loses to — the WireGuard
handshake. Activation was previously reactive only: a data-path packet
or an inbound signal.

This adds a proactive, DNS-time trigger. When the local resolver answers
for an overlay name, it now warms the lazy connection to the peer(s) the
answer points at and waits briefly for one to connect before returning
the response — so by the time the client sends its first packet the
tunnel is already up.

- `dns/local`: new `PeerActivator` capability + `SetPeerActivator`
setter (mirrors the existing `PeerConnectivity`/`SetPeerConnectivity`
injection). `ServeDNS` warms on the pre-filter answer, so activating a
lazily-idle peer also lets it survive the disconnected-peer filter.
Warm-up is scoped to match-only (non-authoritative) zones — the
synthesized private-service zones and user-created zones — so plain
peer-name lookups in the account's authoritative peer zone never wake
idle peers. No-op when no activator is wired (lazy off) or the answer
carries no peer IPs. Budget is `NB_DNS_LAZY_WARMUP_TIMEOUT` (default 2s,
parsed once at construction, invalid values logged); on timeout the
answer is returned anyway (never SERVFAIL).
- The resolver-facing interfaces (`PeerActivator`, `PeerConnectivity`)
take `netip.Addr` instead of string IPs; record addresses are extracted
as `netip.Addr` (v4-mapped forms unmapped) and converted to string only
at the `peer.Status` boundary.
- `SetPeerActivator` is part of the `dns.Server` interface (no-op on the
mock), so the engine wires it without a type assertion.
- `client/internal`: a small engine-side adapter (`dnsPeerActivator`)
resolves answer IPs to peers via `Status.PeerStateByIP`, activates them
through `ConnMgr.ActivatePeer` (HA fan-out included), and polls
`PeerStateByIP` until one is connected. The activation dial is tied to
the engine's long-lived context so a handshake that outlasts the
per-query wait still completes in the background. `ConnMgr.ActivatePeer`
is safe for concurrent use (the lazy manager pointer is guarded by a
dedicated RWMutex and the manager is internally synchronized), so the
DNS path never contends with network-map processing on `syncMsgMux`.

Scope is overlay-only for free: the trigger lives in the local resolver,
which only answers for NetBird-managed names; public/upstream DNS is
unaffected. Already-connected peers short-circuit, so steady-state DNS
latency is unchanged.

## Tests

- `dns/local`: warm-up invokes the activator with the answer's peer
address in match-only zones; authoritative-zone answers never trigger
warm-up; no-activator path unchanged; no-answer queries don't invoke the
activator; `NB_DNS_LAZY_WARMUP_TIMEOUT` parsing
(valid/invalid/non-positive); `extractRecordAddr` unmaps v4-mapped
record data.
- `client/internal`: `dnsPeerActivator` skips
connected/unknown/conn-less peers with no wait, returns as soon as a
pending peer connects, and releases the DNS response at the budget when
the peer stays idle; `ConnMgr.ActivatePeer` races the manager lifecycle
cleanly under `-race`.

a12a3e4603 [client] Keep session deadline visible across reconnects (#6847)
## Describe your changes

The tray session row flapped on every transient engine restart and went
blank at the exact moment the session expired:

- Watcher.Close zeroed the server-scoped recorder deadline on every
engine restart (sleep/wake, network change, stream errors), hiding the
tray row until the next successful login re-seeded it. Close now only
stops the timers; the client run loop clears the recorder when it exits
for real.
- Status.GetSessionExpiresAt masked past deadlines as zero, so the
status snapshot dropped the field right when the UI should have shown
"session expired". The getter now returns the raw value and the tray
renders past deadlines as "Session expired — sign in again", routing the
click to the login flow.
- The watcher rejected recently-expired deadlines (30s skew) delivered
by login/sync, clearing the recorder instead of surfacing the expiry.
Deadlines up to 30 days past are now recorded as expired; only older
values are rejected as garbage.

b6cd8944b1 [client] Fix nil context panic in iOS dynamic route resolver (#6848)
## Describe your changes

getIPsFromResolver passed a nil context to ExchangeWithFallback, which
net.Dialer.DialContext rejects with panic("nil context"). On iOS this
crashed the whole network extension (SIGABRT) ~2 seconds after connect
whenever the network map contained a domain-based (dynamic) route, as
the resolver goroutine panicked on its first DNS query.

Passing nil used to be a documented input of ExchangeWithFallback ("If
the passed context is nil, this will use Exchange instead of
ExchangeContext") since #3632. 9ed2e2a5b (#5971) removed the nil-context
branch, but this iOS-only caller was not updated — it never fails CI
since route_ios.go only builds with GOOS=ios. Broken since v0.71.1.

Pass a context bounded by the existing dialTimeout instead, matching the
dnsinterceptor pattern (context.Background() + timeout).

Captured panic (netbird.err):
  panic: nil context
  net.(*Dialer).DialContext -> miekg/dns ExchangeContext ->
nbdns.ExchangeWithFallback(nil, ...) ->
dynamic.(*Route).getIPsFromResolver
  route_ios.go:35

3f8c447378 [client] Rename isValidAccessToken to reflect audience-only check (#6806)
## Describe your changes

`isValidAccessToken` only decodes the JWT payload and checks the
audience
claim, but its name suggested full token validation. Rename it to
`validateTokenAudience` and document what it does: a client-side
audience/shape
check on a token just obtained from the IdP over TLS. Token authenticity
is
enforced server-side by the management server, which verifies the
signature
against the IdP's JWKS (`shared/auth/jwt/validator.go`) on every
request.

Also harden the parser: a non-empty token lacking the three-part JWT
structure
caused an index-out-of-range panic (`strings.Split(token, ".")[1]`); the
shape
is now validated first. `parseEmailFromIDToken` is documented as
best-effort UX
data (login hint/display), never used for authorization. Added tests for
audience matching, malformed tokens, and the panic regression.

Changes:

- Rename `isValidAccessToken` → `validateTokenAudience`; document that
it does
not verify the signature and that authenticity is enforced server-side.
- Fix an index-out-of-range panic on a non-empty token lacking JWT
structure
(`strings.Split(token, ".")[1]`) by validating the three-part shape
first.
- Document `parseEmailFromIDToken` as best-effort/unverified, used only
for the
  login-hint/display UX, never for an authorization decision.
- Add `util_test.go` covering audience matching (string and array),
missing
  audience, malformed payloads, and the panic regression.

## Issue ticket number and link

Internal cleanup: rename a misleadingly-named client-side helper and
harden JWT
parsing against malformed input (`client/internal/auth/util.go`).

141f3d0390 [client] Fix DNS probe listener impossible panic on unparseable local address (#6797)
generateFreePort used netip.MustParseAddrPort on the OS-produced
LocalAddr().String(), which panics on address strings that don't parse.
Eliminate the parsing entirely by reading the port from the concrete
*net.UDPAddr that net.ListenUDP returns, and construct the bind address
directly. The probe listener is bound with udp4 so only an IPv4 wildcard
address is ever used.

a48618c074 [client] Fix forwarder peers never excluded from lazy connections (#6674)
* [client] Extract peerRoutesAddr helper in toExcludedLazyPeers

Refactor: pull the AllowedIPs match into a named
peerRoutesAddr helper and document why forward-target peers are excluded
from lazy connections. No behavior change; the existing address match is
preserved as-is.

* [client] Add failing test for lazy-conn forward-target exclusion

toExcludedLazyPeers compares AllowedIPs (CIDR) against the unmasked
TranslatedAddress, so forward-target peers are never excluded. This test
asserts the peer is excluded and fails on the current behavior; the fix
follows.

* [client] Fix lazy-conn exclusion for ingress forward peers

peerRoutesAddr compared AllowedIPs (CIDR, e.g. a peer's overlay IP as /32)
against the unmasked TranslatedAddress string, so the match never fired and
forward-target peers were never excluded from lazy connections. Use prefix
containment so a routed address matches the peer's AllowedIP

* [client] Reuse parsed AllowedIPs from peerStore in lazy exclusion

Instead of re-parsing the network map AllowedIPs strings, look up the
already-parsed []netip.Prefix from peerStore.AllowedIPs (the same typed
value the lazy manager itself consumes). A down/lazy peer still has its
conn in the store, so exclusion is unaffected by connection state. Extract
a pure prefixesContain helper and unit-test it.

39193396f5 [client] Fix WGWatcher silently failing to restart on fast disconnect/reconnect (#6664)
* Stick new watcher creation to actual existence of af the conn

and its removal to the removal of such same conn.
Avoid debouncing and cross lock dead locking

* Discriminate not updated from timeout handshakes

* [Recheck watcher ctx cancellation under conn.mu in onWGDisconnected

onWGDisconnected only checked conn.ctx (the engine-scoped context), never
the watcher's own context. disableWgWatcherIfNeeded cancels the wgWatcherCtx,
not conn.ctx, so a disabled watcher's timeout callback did not see the
cancellation.

handshakeCheck runs lock-free, so between the ctx check in periodicHandshakeCheck
and acquiring conn.mu a fast disconnect/reconnect can slip in: the stale watcher
then acquires the lock and tears down the *new*, healthy connection based on the
old timeout, forcing the guard into an unnecessary reconnect (flap).

Recheck watcherCtx.Err() under conn.mu so a superseded watcher exits without
touching the connection that replaced it.

* Remove verbose comments

* Fixup merge conflict leftovers

* Fixup context brought by onWGDisconnected

8e02154bf5 [client] Add SSO login flow timing instrumentation (#6717)
Users reported long delays between finishing browser authentication and
the client connecting. Logs could not attribute the time: the PKCE and
device flows were silent between issuing the auth URL and returning the
token, and nothing recorded when the GUI issued the Up request after
WaitSSOLogin completed.

Add log lines covering the full chain: PKCE callback arrival and token
exchange duration, device-flow polling and approval timing, GUI-side
brackets around WaitSSOLogin and Up, daemon-side Up arrival and
WaitSSOLogin return, and a frontend stall detector that reports when
webview timers were suspended (macOS App Nap / hidden-window
throttling), which delays the WaitSSOLogin-to-Up handoff.

91acb8147c [management,client] 0.75.0 release with new desktop UI (#6473)
- **Wails v3 application** (`client/ui`) with a React + TypeScript + Tailwind frontend replacing the Fyne UI: main connection view, exit-node switcher, networks/peers browser with detail panels, profile management, settings (general, network, SSH, security, troubleshooting, appearance), debug-bundle creation, and a first-run welcome flow.
- **Internationalization**: go-i18n bundle with 9 locales (en, de, es, fr, hu, it, pt, ru, zh-CN) shared between the tray and the frontend.
- **New system tray** implementation with per-platform theme-aware icons, including a native XEmbed host for Linux (`xembed_tray_linux.c`) and a Linux theme watcher.
- **Session handling**: auth session watcher (`client/internal/auth/sessionwatch`), pending login flow, session-expiration dialog and tray notifications, and `netbird login` improvements.
- **Daemon API extensions** (`daemon.proto`): status stream subscription, event stream, networks/exit-node selection endpoints, and richer full status — with probe throttling on the daemon side to protect against UI-driven request storms.
- **UI preferences store** persisted per profile, autostart management via the daemon (single source of truth in HKCU on Windows).
- **Build system**: Taskfile-based builds per platform (macOS, Linux, Windows), Docker cross-compilation images, MSIX/NSIS/nfpm/AppImage packaging, and a new `frontend-ui` CI workflow.

f6900fb07c [client] backport enforce a single selected exit node (#6640)
* routemanager: enforce a single selected exit node

Backport of the exit-node exclusivity reconcile from the 0.75.0 line
(upstream commit 966fbec11) onto v0.74.0. Exit nodes are mutually
exclusive, but the RouteSelector stores routes with default-on semantics,
so every available exit node reported as selected at once.

Reconcile exit-node selection on each network map: keep at most one
selected -- the user's persisted pick, else whatever management marks for
auto-apply (SkipAutoApply=false), else none. Never auto-activate an exit
node the map does not request.

Carries over only the manager/routeselector logic and its test; the
desktop-only client/server changes and the BumpNetworksRevision UI-push
feature from the original commit are intentionally excluded.

* routeselector: make exit-node reconciliation atomic

enforceSingleExitNode took the RouteSelector lock three separate times
(IsDeselectAll, then DeselectRoutes, then SelectRoutes), so a concurrent
DeselectAllRoutes could interleave and be silently undone: SelectRoutes on
its deselectAll branch clears the flag and re-selects the preferred exit
node, overriding the user's "all off".

Move the whole reconciliation into a single locked RouteSelector method
(SetExclusiveExitNode) that checks deselectAll inside the critical section,
so a deselect-all either fully precedes the reconcile (left untouched) or
fully follows it (honoured). No interleaving is possible.

06839a4731 [client] Fix race between WG watcher initial handshake read and endpoint creation (#6626)
* [client] Fix race between WG watcher initial handshake read and endpoint config

The watcher's initial handshake read ran in a separate goroutine with no
ordering guarantee relative to the WireGuard endpoint configuration, so it
would sometimes race with the peer being added to the interface. Split
enabling into a synchronous PrepareInitialHandshake, called before the
endpoint is configured, and an EnableWgWatcher that only runs the
monitoring loop, making the baseline read deterministic and keeping it
correct for reconnects where the peer's WireGuard entry survives.

* [client] Skip WG watcher disconnect callback when context is cancelled

A superseded or cancelled watcher whose handshake-check timer fires before
it observes ctx.Done() would still invoke onDisconnectedFn, tearing down a
now-healthy connection. Re-check ctx before firing the disconnect and
handshake-success callbacks and stand down silently if it was cancelled.

980598ed4a [management, client] Add management-controlled client metrics push (#5886)
* [management, client] Add management-controlled client metrics push

Allow enabling/disabling client metrics push from the dashboard via
account settings instead of requiring env vars on every client.

- Add MetricsConfig proto message to NetbirdConfig
- Add MetricsPushEnabled to account Settings (DB-persisted)
- Expose metrics_push_enabled in OpenAPI and dashboard API handler
- Populate MetricsConfig in sync and login responses
- Client dynamically starts/stops push based on management config
- NB_METRICS_PUSH_ENABLED env var overrides management when explicitly set
- Add activity events for metrics push enable/disable

* Remove log line

* [management] Fix peer update test for MetricsConfig in NetbirdConfig

Update TestUpdateAccountPeers assertions: NetbirdConfig is no longer
nil in peer update responses since it now carries MetricsConfig even
when STUN/TURN config is absent.

* Regenerate proto files with protoc v7.34.1

* [management] Read metrics push setting in Postgres account query

getAccountPgx omitted settings_metrics_push_enabled from its hand-written
SELECT and Scan, so the toggle was always read back as false on Postgres
and never reached clients.

* [client] Fix metrics push getting stuck off after engine restart

Engine restarts (backoff retries within the same login session) cancel
e.ctx, which the push goroutine's lifetime was tied to. The goroutine
died silently but ClientMetrics.push stayed non-nil since only an
explicit stop clears it, so the next UpdatePushFromMgm call saw a
"push already running" state and never restarted it.

Give the Engine its own metricsCtx sourced from ConnectClient.ctx,
which outlives engine restarts, so handleMetricsUpdate stops tying the
push to the wrong-scoped context. Additionally make ClientMetrics.push
an atomic.Pointer that the push goroutine clears via CompareAndSwap on
exit, so the tracked state can never drift from the goroutine's actual
lifetime regardless of which context a future caller passes in.

* [management] Regenerate OpenAPI types with oapi-codegen v2.7.1

types.gen.go was regenerated with a stale local v2.6.0 binary,
causing the CI git-diff check against generate.sh's pinned v2.7.1
to fail.
