* [client] Batch macOS DNS domains across multiple scutil keys to avoid truncation
scutil has undocumented limits: 99-element cap on d.add arrays and ~2048
byte value buffer for SupplementalMatchDomains. Users with 60+ domains
hit silent domain loss. This applies the same batching approach used on
Windows (nrptMaxDomainsPerRule=50), splitting domains into indexed
resolver keys (NetBird-Match-0, NetBird-Match-1, etc.) with 50-element
and 1500-byte limits per key.
* check for all keys on getRemovableKeysWithDefaults
* use multi error
* Refactor WG endpoint setup with role-based proxy activation
For relay connections, the controller (initiator) now activates the
wgProxy before configuring the WG endpoint, while the non-controller
(responder) configures the endpoint first with a delayed update, then
activates the proxy after. This prevents the responder from sending
traffic through the proxy before WireGuard is ready to receive it,
avoiding handshake congestion when both sides try to initiate
simultaneously.
For ICE connections, pass hasRelayBackup as the setEndpointNow flag
so the responder sets the endpoint immediately when a relay fallback
exists (avoiding the delayed update path since relay is already
available as backup).
On ICE disconnect with relay fallback, remove the duplicate
wgProxyRelay.Work() calls — the relay proxy is already active from
initial setup, so re-activating it is unnecessary.
In EndpointUpdater, split ConfigureWGEndpoint into explicit
configureAsInitiator and configureAsResponder paths, and add the
setEndpointNow parameter to let the caller control whether the
responder applies the endpoint immediately or defers it. Add unused
SwitchWGEndpoint and RemoveEndpointAddress methods. Remove the
wgConfigWorkaround sleep from the relay setup path.
* Fix redundant wgProxyRelay.Work() call during relay fallback setup
* Simplify WireGuard endpoint configuration by removing unused parameters and redundant logic
When an ICE connection disconnects and falls back to relay, reset the
WireGuard endpoint and handshake watcher if the remote peer's ICE session
has changed. This ensures the controller re-establishes a fresh WireGuard
handshake rather than waiting on a stale endpoint from the previous session.
* Optimize Windows DNS performance with domain batching and batch mode
Implement two-layer optimization to reduce Windows NRPT registry operations:
1. Domain Batching (host_windows.go):
- Batch domains per NRPT
- Reduces NRPT rules by ~97% (e.g., 184 domains: 184 rules → 4 rules)
- Modified addDNSMatchPolicy() to create batched NRPT entries
- Added comprehensive tests in host_windows_test.go
2. Batch Mode (server.go):
- Added BeginBatch/EndBatch methods to defer DNS updates
- Modified RegisterHandler/DeregisterHandler to skip applyHostConfig in batch mode
- Protected all applyHostConfig() calls with batch mode checks
- Updated route manager to wrap route operations with batch calls
* Update tests
* Fix log line
* Fix NRPT rule index to ensure cleanup covers partially created rules
* Ensure NRPT entry count updates even on errors to improve cleanup reliability
* Switch DNS batch mode logging from Info to Debug level
* Fix batch mode to not suppress critical DNS config updates
Batch mode should only defer applyHostConfig() for RegisterHandler/
DeregisterHandler operations. Management updates and upstream nameserver
failures (deactivate/reactivate callbacks) need immediate DNS config
updates regardless of batch mode to ensure timely failover.
Without this fix, if a nameserver goes down during a route update,
the system DNS config won't be updated until EndBatch(), potentially
delaying failover by several seconds.
Or if you prefer a shorter version:
Fix batch mode to allow immediate DNS updates for critical paths
Batch mode now only affects RegisterHandler/DeregisterHandler.
Management updates and nameserver failures always trigger immediate
DNS config updates to ensure timely failover.
* Add DNS batch cancellation to rollback partial changes on errors
Introduces CancelBatch() method to the DNS server interface to handle error
scenarios during batch operations. When route updates fail partway through, the DNS
server can now discard accumulated changes instead of applying partial state. This
prevents leaving the DNS configuration in an inconsistent state when route manager
operations encounter errors.
The changes add error-aware batch handling to prevent partial DNS configuration
updates when route operations fail, which improves system reliability.

Add defensive nil checks in ThreadSafeAgent.Close() to prevent panic
when agent field is nil. This can occur during Windows suspend/resume
when network interfaces are disrupted or the pion/ice library returns
nil without error.
Also capture agent pointer in local variable before goroutine execution
to prevent race conditions.
Fixes service crashes on laptop wake-up.
Avoid repeated conversions during route setup. The toInterface helper ensures
the conversion happens only once regardless of how many routes are added
or removed.
Start the WireGuard watcher before configuring the WG endpoint to ensure it captures the initial handshake timestamp.
Previously, the watcher was started after endpoint configuration, causing it to miss the handshake that occurred during setup.
* Consolidate authentication logic
- Moving auth functions from client/internal to client/internal/auth package
- Creating unified auth.Auth client with NewAuth() constructor
- Replacing direct auth function calls with auth client methods
- Refactoring device flow and PKCE flow implementations
- Updating iOS/Android/server code to use new auth client API
* Refactor PKCE auth and login methods
- Remove unnecessary internal package reference in PKCE flow test
- Adjust context assignment placement in iOS and Android login methods
Per RFC 4592 section 2.2.1, wildcards should only match when the queried
name does not exist in the zone. Previously, if host.example.com had an
A record and *.example.com had an AAAA record, querying AAAA for
host.example.com would incorrectly return the wildcard AAAA instead of
NODATA.
Now the resolver checks if the domain exists (with any record type)
before falling back to wildcard matching, returning proper NODATA
responses for existing names without the requested record type.
* [client] Add WGConfigurer interface
To allow Rosenpass to work both with kernel
WireGuard via wgctrl (default behavior) and
userspace WireGuard via IPC on Android/iOS
using WGUSPConfigurer
* [client] Remove Rosenpass debug logs
* [client] Return simpler peer configuration in outputKey method
ConfigureDevice, the method previously used in
outputKey via wgClient to update the device's
properties, is now defined in the WGConfigurer
interface and implemented both in kernel_unix and
usp configurers.
PresharedKey datatype was also changed from
boolean to [32]byte to compare it
to the original NetBird PSK, so that Rosenpass
may replace it with its own when necessary.
* [client] Remove unused field
* [client] Replace usage of WGConfigurer
Replaced with preshared key setter interface,
which only defines a method to set / update the preshared key.
Logic has been migrated from rosenpass/netbird_handler to client/iface.
* [client] Use same default peer keepalive value when setting preshared keys
* [client] Store PresharedKeySetter iface in rosenpass manager
To avoid no-op if SetInterface is called before generateConfig
* [client] Add mutex usage in rosenpass netbird handler
* [client] change implementation setting Rosenpass preshared key
Instead of providing a method to configure a device (device/interface.go),
it forwards the new parameters to the configurer (either
kernel_unix.go / usp.go).
This removes dependency on reading FullStats, and makes use of a common
method (buildPresharedKeyConfig in configurer/common.go) to build a
minimal WG config that only sets/updates the PSK.
netbird_handler.go now keeps s list of initializedPeers to choose whether
to set the value of "UpdateOnly" when calling iface.SetPresharedKey.
* [client] Address possible race condition
Between outputKey calls and peer removal; it
checks again if the peer still exists in the
peers map before inserting it in the
initializedPeers map.
* [client] Add psk Rosenpass-initialized check
On client/internal/peer/conn.go, the presharedKey
function would always return the current key
set in wgConfig.presharedKey.
This would eventually overwrite a key set
by Rosenpass if the feature is active.
The purpose here is to set a handler that will
check if a given peer has its psk initialized
by Rosenpass to skip updating the psk
via updatePeer (since it calls presharedKey
method in conn.go).
* Add missing updateOnly flag setup for usp peers
* Change common.go buildPresharedKeyConfig signature
PeerKey datatype changed from string to
wgTypes.Key. Callers are responsible for parsing
a peer key with string datatype.
* **New Features**
* Wildcard DNS fallback for eligible query types (excluding NS/SOA): attempts wildcard records when no exact match, rewrites wildcard names back to the original query, and rotates responses; preserves CNAME resolution.
* **Tests**
* Vastly expanded coverage for wildcard behaviors, precedence, multi-record round‑robin, multi-type chains, multi-hop and cross-zone scenarios, and edge cases (NXDOMAIN/NODATA, fallthrough).
* **Chores**
* CI lint config updated to ignore an additional codespell entry.
* **New Features**
* SSH server JWT validation now accepts multiple audiences with backward-compatible handling of the previous single-audience setting and a guard ensuring at least one audience is configured.
* **Tests**
* Test suites updated and new tests added to cover multiple-audience scenarios and compatibility with existing behavior.
* **Other**
* Startup logging enhanced to report configured audiences for JWT auth.

Adds a per-instance uint64 hash to DefaultServer to detect identical merged host DNS configs (including extra domains). applyHostConfig computes and compares the hash, skips applying if unchanged, treats hash errors as a fail-safe (proceed to apply), and updates the stored hash only after successful hashing and apply.
Expose the profile-manager service for Android. Logout was not part of the manager service implementation. In the future, I recommend moving this logic there.
