* 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
* 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.

Enhance the user experience by enabling authentication to Netbird using Single Sign-On (SSO) with any Identity Provider (IDP) provider. Current client offers this capability through the Device Authorization Flow, however, is not widely supported by many IDPs, and even some that do support it do not provide a complete verification URL.
To address these challenges, this pull request enable Authorization Code Flow with Proof Key for Code Exchange (PKCE) for client logins, which is a more widely adopted and secure approach to facilitate SSO with various IDP providers.
