4fec709bb1 Release 0.28.0 (#2092)
* 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.

961d9198ef Fix removeAllowedIP (#1913)
Current implementation of removeAllowedIP recreates the wg iface,
killing all open ports and connections. This is due to that "lines" is
the complete output of `get` from wg-usp and not the specific interface
which changes should be applied to.

2475473227 Support client default routes for Linux (#1667)
All routes are now installed in a custom netbird routing table.
Management and wireguard traffic is now marked with a custom fwmark.
When the mark is present the traffic is routed via the main routing table, bypassing the VPN.
When the mark is absent the traffic is routed via the netbird routing table, if:
- there's no match in the main routing table
- it would match the default route in the routing table

IPv6 traffic is blocked when a default route IPv4 route is configured to avoid leakage.

5de4acf2fe Integrate Rosenpass (#1153)
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.

e37a337164 Add gosec linter (#1342)
This PR adds `gosec` linter with the following checks disabled:

- G102: Bind to all interfaces
- G107: Url provided to HTTP request as taint input
- G112: Potential slowloris attack
- G114: Use of net/http serve function that has no support for setting timeouts
- G204: Audit use of command execution
- G401: Detect the usage of DES, RC4, MD5 or SHA1
- G402: Look for bad TLS connection settings
- G404: Insecure random number source (rand)
- G501: Import blocklist: crypto/md5
- G505: Import blocklist: crypto/sha1

We have complaints related to the checks above. They have to be addressed separately.

c9b2ce08eb DNS forwarder and common ebpf loader (#1083)
In case the 53 UDP port is not an option to bind then we hijack the DNS traffic with eBPF, and we forward the traffic to the listener on a custom port. With this implementation, we should be able to listen to DNS queries on any address and still set the local host system to send queries to the custom address on port 53.

Because we tried to attach multiple XDP programs to the same interface, I did a refactor in the WG traffic forward code also.

bb40325977 Update GitHub Actions and Enhance golangci-lint (#1075)
This PR showcases the implementation of additional linter rules. I've updated the golangci-lint GitHub Actions to the latest available version. This update makes sure that the tool works the same way locally - assuming being updated regularly - and with the GitHub Actions.

I've also taken care of keeping all the GitHub Actions up to date, which helps our code stay current. But there's one part, goreleaser that's a bit tricky to test on our computers. So, it's important to take a close look at that.

To make it easier to understand what I've done, I've made separate changes for each thing that the new linters found. This should help the people reviewing the changes see what's going on more clearly. Some of the changes might not be obvious at first glance.

Things to consider for the future
CI runs on Ubuntu so the static analysis only happens for Linux. Consider running it for the rest: Darwin, Windows

b0364da67c Wg ebpf proxy (#911)
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

7ebe58f20a Feature/permanent dns (#967)
* Add DNS list argument for mobile client

* Write testable code

Many places are checked the wgInterface != nil condition.
It is doing it just because to avoid the real wgInterface creation for tests.
Instead of this involve a wgInterface interface what is moc-able.

* Refactor the DNS server internal code structure

With the fake resolver has been involved several
if-else statement and generated some unused
variables to distinguish the listener and fake
resolver solutions at running time. With this
commit the fake resolver and listener based
solution has been moved into two separated
structure. Name of this layer is the 'service'.
With this modification the unit test looks
simpler and open the option to add new logic for
the permanent DNS service usage for mobile
systems.



* Remove is running check in test

We can not ensure the state well so remove this
check. The test will fail if the server is not
running well.

ecac82a5ae Share kernel Wireguard port with raw socket (#826)
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.

2eeed55c18 Bind implementation (#779)
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.
