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.
- 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)
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.
This introduces a disabled-by-default allow-remote-jobs setting that
controls whether the management server may run jobs (such as debug
bundles) on a peer. The flag propagates end to end: through client
configuration, the daemon SetConfig and Login requests, authentication,
and system info, up to management, where it is stored on the peer and
exposed on the peers API as remote_jobs_allowed. The client refuses any
management-requested job unless the peer has opted in. Because enabling
remote jobs crosses the user-to-root boundary, turning it on requires
privilege, mirroring the SSH-server gate. Administrators can enforce the
setting through MDM policy on both macOS and Windows, and MDM can also
override the debug-bundle upload URL. The change ships policy
documentation and generated profile templates, and adds configuration,
conflict, and enforcement tests covering the opt-in, privilege, and MDM
paths.
* [client] Resolve profiles for the sudo invoking user instead of root
The SSH server flags force `netbird up` through sudo, but the CLI resolved
every per-user path with the process user. As root that reads root's own
(empty) local state, so a `sudo netbird up` silently switched the daemon from
the user's profile to the default one — cancelling any login already waiting
in the browser — and then ran an SSO login for the default profile's config.
Whichever account that login returned, the default profile's peer belongs to
someone else, so every attempt ended in "peer is already registered by a
different User or a Setup Key", with nothing telling the user why.
Resolve the acting user through SUDO_USER when running as root: the active
profile, the profile config paths and the stored account email now come from
the invoking user's directories. Privilege decisions are untouched — they stay
on the kernel credentials of the daemon connection, which an environment
variable can never influence; a forged SUDO_USER only selects a profile root
could select anyway.
The invoking user's directories are strictly read-only under sudo. Anything
root wrote there would be root-owned and break the user's own runs, so instead
of chowning files back, the local writes are skipped: the active-profile
bookkeeping and the account-email state simply do not update from a sudo run
(the daemon records the switch on its side; a skipped email write costs at
most one extra account prompt later).
Plain root — no sudo context — has no user to act for, so the ambiguity is
refused instead of guessed at: when the daemon's active profile differs from
what root resolves and no --profile was given, up fails with a message naming
both profiles, instead of silently switching the daemon and failing later with
the ownership error.
* [client] Act on the daemon-resolved profile and fail closed in the root guard
Under sudo the local active-profile mirror is not updated, so up/login
re-reading it after a profile switch acted on the previous profile; use
the daemon-resolved ID directly instead. The plain-root guard now runs
after the readiness wait, denies on lookup errors and empty responses,
and matches the owning username as well; an unowned profile (fresh
install) and a daemon predating the RPC stay allowed. Write-skip
decisions key off the sudo environment alone so a transient user lookup
failure cannot turn a run into writing root-owned files into the user's
directory, and RemoveProfileState honors the read-only rule too.
* [client] Return a wrapped error instead of double-reporting the dial failure
* [client] Read the profile from the daemon when the local mirror is not authoritative
Under sudo without --profile, `up` took the active profile from the invoking
user's local active_profile.txt mirror and drove the daemon to it. But that
mirror is never written under sudo (the SwitchProfile write is a no-op), so it
goes stale after any --profile run and silently switches the daemon back to the
mirror's default. The plain-root guard was meant to refuse exactly this
ambiguity but only ran for plain root, never for the sudo case the fix targets.
When there is no --profile and the mirror is not authoritative (sudo or plain
root), take the profile the daemon already holds for the invoking user instead
of the stale mirror: stay on the user's current profile when the daemon owns it
(or it is unowned, as on a fresh install), and refuse with a --profile hint when
the daemon is on another user's profile. A daemon predating the RPC keeps the
mirror-derived profile.
Reproduce (before this change):
1. As a non-root user misha, with the daemon installed and running:
sudo netbird up --profile work
misha connects on the `work` profile.
2. Because the local mirror write is skipped under sudo,
~misha/.config/netbird/active_profile.txt still says `default` (or is still
absent, which also resolves to `default`).
3. Run a bare:
sudo netbird up
The CLI reads `default` from the frozen mirror and sends ProfileName=default;
the daemon silently switches away from `work` and brings the tunnel up on
`default` — a different account/peer than the one last chosen, with no
warning. After this change step 3 stays on `work`.
* [client] Return a sentinel error instead of nil-nil for the missing daemon RPC
* [client] Load the extend-session hint from the resolved profile
* [client] Fail closed instead of reading root's config when the sudo user lookup fails
* [client] Fail closed in InvokingUser when the sudo user lookup fails
A previous change made baseConfigDir fail closed when SUDO_USER cannot be
resolved, but InvokingUser still fell through to user.Current(). Those two
guards disagreed: the active-profile mirror and the email state refused to
read root's directory, while every profile-path caller happily resolved as
root.
The consequence of a transient NSS failure under sudo was that
Profile.FilePath resolved through getConfigDirForUser("root"), creating
/var/lib/netbird/root and reading the profile JSON from there, and the CLI
sent Username "root" to the daemon in SetConfig and ListProfiles, so the
daemon resolved the same phantom namespace. The invoking user was silently
moved onto a root-owned profile instead of being told the lookup failed.
Fail closed at the single source of the fallback. getConfigDirForUser is
left alone on purpose: it is a pure path helper that also serves
daemon-supplied usernames, and under sudo with a successful lookup it must
still create the invoking user's own profile directory.
* Improved residual state restoration during foreground startup and
foreground login, ensuring consistent recovery with stale states.
* Foreground flows now initialize advanced routing so stale routes
are bypassed during login.
* Restores behavior to create profile if not there on Up
* Allows to restore nerbird status showing of the profile name
* [client] Reduce upFunc cognitive complexity
Extract the profile switch/auto-create logic from upFunc into a dedicated
switchOrCreateProfile helper. The inlined NotFound-retry branch pushed
upFunc over SonarCloud's cognitive complexity threshold (S3776).
No behavior change.

* [client] Make up --profile auto-create idempotent under concurrent runs
Don't fail switchOrCreateProfile on a createProfile error: a concurrent
run may create the profile between the NotFound check and our create
call. Retry the switch regardless and only surface the create error if
the switch also fails. Addresses CodeRabbit race-condition feedback.

Auto-update logic moved out of the UI into a dedicated updatemanager.Manager service that runs in the connection layer. The
UI no longer polls or checks for updates independently.
The update manager supports three modes driven by the management server's auto-update policy:
No policy set by mgm: checks GitHub for the latest version and notifies the user (previous behavior, now centralized)
mgm enforces update: the "About" menu triggers installation directly instead of just downloading the file — user still initiates the action
mgm forces update: installation proceeds automatically without user interaction
updateManager lifecycle is now owned by daemon, giving the daemon server direct control via a new TriggerUpdate RPC
Introduces EngineServices struct to group external service dependencies passed to NewEngine, reducing its argument count from 11 to 4
This PR improves the NetBird client's status checking mechanism by implementing earlier detection of client state changes and better handling of connection lifecycle management. The key improvements focus on:
• Enhanced status detection - Added waitForReady option to StatusRequest for improved client status handling
• Better connection management - Improved context handling for signal and management gRPC connections• Reduced connection timeouts - Increased gRPC dial timeout from 3 to 10 seconds for better reliability
• Cleaner error handling - Enhanced error propagation and context cancellation in retry loops
Key Changes
Core Status Improvements:
- Added waitForReady optional field to StatusRequest proto (daemon.proto:190)
- Enhanced status checking logic to detect client state changes earlier in the connection process
- Improved handling of client permanent exit scenarios from retry loops
Connection & Context Management:
- Fixed context cancellation in management and signal client retry mechanisms
- Added proper context propagation for Login operations
- Enhanced gRPC connection handling with better timeout management
Error Handling & Cleanup:
- Moved feedback channels to upper layers for better separation of concerns
- Improved error handling patterns throughout the client server implementation
- Fixed synchronization issues and removed debug logging
This will allow running netbird commands (including debugging) against the daemon and provide a flow similar to non-container usages.
It will by default both log to file and stderr so it can be handled more uniformly in container-native environments.
With the lazy connection feature, the peer will connect to target peers on-demand. The trigger can be any IP traffic.
This feature can be enabled with the NB_ENABLE_EXPERIMENTAL_LAZY_CONN environment variable.
When the engine receives a network map, it binds a free UDP port for every remote peer, and the system configures WireGuard endpoints for these ports. When traffic appears on a UDP socket, the system removes this listener and starts the peer connection procedure immediately.
Key changes
Fix slow netbird status -d command
Move from engine.go file to conn_mgr.go the peer connection related code
Refactor the iface interface usage and moved interface file next to the engine code
Add new command line flag and UI option to enable feature
The peer.Conn struct is reusable after it has been closed.
Change connection states
Connection states
Idle: The peer is not attempting to establish a connection. This typically means it's in a lazy state or the remote peer is expired.
Connecting: The peer is actively trying to establish a connection. This occurs when the peer has entered an active state and is continuously attempting to reach the remote peer.
Connected: A successful peer-to-peer connection has been established and communication is active.

This update adds new relay integration for NetBird clients. The new relay is based on web sockets and listens on a single port.
- Adds new relay implementation with websocket with single port relaying mechanism
- refactor peer connection logic, allowing upgrade and downgrade from/to P2P connection
- peer connections are faster since it connects first to relay and then upgrades to P2P
- maintains compatibility with old clients by not using the new relay
- updates infrastructure scripts with new relay service
* Enable network monitoring by default for Windows and Darwin
* Enable network monitoring by default on Windows and macOS
* fix merge
* Prevent updating config if no changes
* compile client under freebsd (#1620)
Compile netbird client under freebsd and now support netstack and userspace modes.
Refactoring linux specific code to share same code with FreeBSD, move to *_unix.go files.
Not implemented yet:
Kernel mode not supported
DNS probably does not work yet
Routing also probably does not work yet
SSH support did not tested yet
Lack of test environment for freebsd (dedicated VM for github runners under FreeBSD required)
Lack of tests for freebsd specific code
info reporting need to review and also implement, for example OS reported as GENERIC instead of FreeBSD (lack of FreeBSD icon in management interface)
Lack of proper client setup under FreeBSD
Lack of FreeBSD port/package
* Add DNS routes (#1943)
Given domains are resolved periodically and resolved IPs are replaced with the new ones. Unless the flag keep_route is set to true, then only new ones are added.
This option is helpful if there are long-running connections that might still point to old IP addresses from changed DNS records.
* Add process posture check (#1693)
Introduces a process posture check to validate the existence and active status of specific binaries on peer systems. The check ensures that files are present at specified paths, and that corresponding processes are running. This check supports Linux, Windows, and macOS systems.
