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
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
- Have just one manager => one lock
- Session state is needed in driver to => we have it available now.
- Isomorphically align to rosenpass components and functionality

* Run lazy connection manager for rosenpass peers
* Treat forward-target peers as normal lazy connections
* Run Rosenpass in permissive mode on the embedded proxy
* Support per-peer lazy connection state and default proxy peers to lazy
* Classify forward targets from incoming config in lazy exclusion
* Set IsUserspaceBind mock so lazy manager starts in engine test
* Skip lazy exclude reconciliation when the set is unchanged
* Keep cached lazy flag when a sync carries no peer config
Losing the last network only flipped the availability state: the dead management, signal and relay sockets stayed silently connected until their own timeouts, so the client kept reporting Connected with no network at all.
Introduce client/netevents with a Manager that ties the availability state, the connection sweeper and the status recorder together, and move the netstate and netsweep packages under it (netsweep renamed to sweep). SetNetworkAvailable(false) now also sweeps the registered connections so their owners redial and the listener reaches the NoNetwork state.
The Android and iOS bindings own a Manager instance and inject it through the constructors; consumers hold the concrete *Manager whose nil zero value reports always-online and never sweeps, with interfaces kept only as parameter contracts. The relay guard settle wait moved into the Manager as WaitSettled, removing the netevents import from the relay package.
The updater runs as LocalSystem and started netbird-ui via
CreateProcessAsUser with a nil environment, so the UI inherited the
SYSTEM environment (USERPROFILE, APPDATA pointing at systemprofile)
while running under the user's token. The WebView2-based UI exits
immediately in that state, so the UI never came back after an update.
Build the environment from the user's token with CreateEnvironmentBlock
and pass it to CreateProcessAsUser.
Stop the UI before a silent Windows update and suppress the installer reboot
On silent MSI updates msiexec could reboot the machine on its own. The running UI holds a lock on its own exe, and since msiexec runs as LocalSystem it cannot close the interactive user's UI via Restart Manager, so the MSI scheduled the
file replacement for the next reboot and marked the install restart-required.
Terminate netbird-ui.exe before launching the installer and wait until its image file is released; the existing deferred restart brings it back after the install on every exit path
Run msiexec with /norestart REBOOT=ReallySuppress so it never reboots on its own
Treat exit codes 3010/1641 as success with a warning instead of a failure

* [client] Clear stale installer result before starting update
The installer result file could survive a previous update attempt (e.g.
when the updater wrote it after the restarted daemon already ran its
startup check). A new install attempt left the old file in place, so the
GUI progress window's first GetInstallerResult poll read the outdated
result: a stale success made the GUI quit mid-install, which cancelled
the TriggerUpdate context and aborted the artifact verification; a stale
error surfaced a bogus failure dialog for a succeeding update.
Remove any leftover result file at the start of RunInstallation, before
the download begins, so result watchers only see the current attempt's
outcome.
* [client] Align stale-result warning with log message style
On network changes the client restarted the whole engine. That is heavy-handed and slow: it tears down working state to recover from a transition the engine could handle itself. This replaces the restart with proper network event handling.
Suspend the retry loops while no network is available. Instead of burning through backoff intervals against an unreachable network, the reconnection loops park until the OS reports a usable network again.
Reconnect immediately on a network switch. When the OS hands us a new network, connections bound to the old one are swept and re-dialed right away, rather than waiting for a timeout to notice they are dead.
Adds an SSHClient gomobile binding so the Android app can run an SSH session over the tunnel with a PTY, exposed through a listener interface for the in-app terminal.
Server type is auto-detected from the SSH banner, which selects the auth path: JWT device-code flow, NetBird key, or a regular server (NetBird key first, then password). Host keys are verified against the peer registry for NetBird servers and trust-on-first-use for regular ones.
* [client] Pass stored email as login hint from UI and keep it on logout
Follow the CLI pattern: the Wails UI now reads the account email from the
user-owned profile state file and passes it as the OIDC login_hint on login
and session extend, since the daemon-side fallback runs as root and cannot
see the user's state file. Logout no longer deletes the stored email, so a
later login preselects the account at the IdP; profile removal remains the
operation that deletes it.
* [client] Log ignored profile lookup errors in extend-session hint fallback
* [client] Skip IPv6 route tests when the default nexthop is unusable
ensureIPv6DefaultRoute treated a successful netlink RouteAdd as proof that
a usable IPv6 nexthop exists. Installing ::/0 via loopback can succeed while
the kernel still rejects that nexthop for a concrete prefix, which surfaced
on ubuntu22/20260810.260 runners as:
add route to table: netlink add route: invalid argument
Probe the resolved nexthop by installing and removing a discard-prefix route
through the same code path the tests use, and skip when it fails. EEXIST
means the nexthop already carries a route, so it counts as usable.
* [client] Probe the IPv6 nexthop through raw netlink
addRoute swallows EAFNOSUPPORT and EOPNOTSUPP via isOpErr, so a nil return
did not prove the probe route was installed. Call netlink directly so an
unsupported operation skips the test instead of passing as usable.
