This PR implements the following posture checks:
* Agent minimum version allowed
* OS minimum version allowed
* Geo-location based on connection IP
For the geo-based location, we rely on GeoLite2 databases which are free IP geolocation databases. MaxMind was tested and we provide a script that easily allows to download of all necessary files, see infrastructure_files/download-geolite2.sh.
The OpenAPI spec should extensively cover the life cycle of current version posture checks.
In the case of disabled stub listeren the list of name servers is unordered. The solution is to configure the resolv.conf file directly instead of dbus API.
Because third-party services also can manipulate the DNS settings the agent watch the resolv.conf file and keep it up to date.
- apply file type DNS manager if in the name server list does not exist the 127.0.0.53 address
- watching the resolv.conf file with inotify service and overwrite all the time if the configuration has changed and it invalid
- fix resolv.conf generation algorithm
This PR aims to integrate Rosenpass with NetBird. It adds a manager for Rosenpass that starts a Rosenpass server and handles the managed peers. It uses the cunicu/go-rosenpass implementation. Rosenpass will then negotiate a pre-shared key every 2 minutes and apply it to the wireguard connection.
The Feature can be enabled by setting a flag during the netbird up --enable-rosenpass command.
If two peers are both support and have the Rosenpass feature enabled they will create a post-quantum secure connection. If one of the peers or both don't have this feature enabled or are running an older version that does not have this feature yet, the NetBird client will fall back to a plain Wireguard connection without pre-shared keys for those connections (keeping Rosenpass negotiation for the rest).
Additionally, this PR includes an update of all Github Actions workflows to use go version 1.21.0 as this is a requirement for the integration.

Add netstack support for the agent to run it without privileges.
- use interface for tun device
- use common IPC for userspace WireGuard integration
- move udpmux creation and sharedsock to tun layer
Restructure data handling for improved performance and flexibility.
Introduce 'G'-prefixed fields to represent Gorm relations, simplifying resource management.
Eliminate complexity in lookup tables for enhanced query and write speed.
Enable independent operations on data structures, requiring adjustments in the Store interface and Account Manager.
added intergration with JumpCloud User API. Use the steps in setup.md for configuration.
Additional changes:
- Enhance compatibility for providers that lack audience support in the Authorization Code Flow and the Authorization - - Code Flow with Proof Key for Code Exchange (PKCE) using NETBIRD_DASH_AUTH_USE_AUDIENCE=falseenv
- Verify tokens by utilizing the client ID when audience support is absent in providers
In case the route management feature is not supported
then do not create unnecessary firewall and manager instances.
This can happen if the nftables nor iptables is not available on the host OS.
- Move the error handling to upper layer
- Remove fake, useless implementations of interfaces
- Update go-iptables because In Docker the old version can not
determine well the path of executable file
- update lib to 0.70
EBPF proxy between TURN (relay) and WireGuard to reduce number of used ports used by the NetBird agent.
- Separate the wg configuration from the proxy logic
- In case if eBPF type proxy has only one single proxy instance
- In case if the eBPF is not supported fallback to the original proxy Implementation
Between the signature of eBPF type proxy and original proxy has
differences so this is why the factory structure exists
* use ipset for iptables
* Update unit-tests for iptables
* Remove debug code
* Update dependencies
* Create separate sets for dPort and sPort rules
* Fix iptables tests
* Fix 0.0.0.0 processing in iptables with ipset
- wireguard/windows version update to 0.5.3
- follow up forked wireguard-go MTU related changes
- fix MTU settings on Windows

This PR brings support of a shared port between stun (ICE agent) and
the kernel WireGuard
It implements a single port mode for execution with kernel WireGuard
interface using a raw socket listener.
BPF filters ensure that only STUN packets hit the NetBird userspace app
Removed a lot of the proxy logic and direct mode exchange.
Now we are doing an extra hole punch to the remote WireGuard
port for best-effort cases and support to old client's direct mode.
This PR adds supports for the WireGuard userspace implementation
using Bind interface from wireguard-go.
The newly introduced ICEBind struct implements Bind with UDPMux-based
structs from pion/ice to handle hole punching using ICE.
The core implementation was taken from StdBind of wireguard-go.
The result is a single WireGuard port that is used for host and server reflexive candidates.
Relay candidates are still handled separately and will be integrated in the following PRs.
ICEBind checks the incoming packets for being STUN or WireGuard ones
and routes them to UDPMux (to handle hole punching) or to WireGuard respectively.
Default Rego policy generated from the rules in some cases is broken.
This change fixes the Rego template for rules to generate policies.
Also, file store load constantly regenerates policy objects from rules.
It allows updating/fixing of the default Rego template during releases.
