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.
Add a default firewall rule to allow netbird traffic to be handled
by the access control managers.
Userspace manager behavior:
- When running on Windows, a default rule is add on Windows firewall
- For Linux, we are using one of the Kernel managers to add a single rule
- This PR doesn't handle macOS
Kernel manager behavior:
- For NFtables, if there is a filter table, an INPUT rule is added
- Iptables follows the previous flow if running on kernel mode. If running
on userspace mode, it adds a single rule for INPUT and OUTPUT chains
A new checkerFW package has been introduced to consolidate checks across
route and access control managers.
It supports a new environment variable to skip nftables and allow iptables tests
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
The ephemeral manager keep the inactive ephemeral peers in a linked list. The manager schedule a cleanup procedure to the head of the linked list (to the most deprecated peer). At the end of cleanup schedule the next cleanup to the new head.
If a device connect back to the server the manager will remote it from the peers list.
This adds a basic wxs file to build MSI installer
This file was created using docs
from https://wixtoolset.org/docs/schema/wxs/ and
examples from gsudo, qemu-shoggoth, and many others.
The main difference between this and the .exe installer
is that we don't use the netbird service command to install
the daemon
The API authentication with PATs was not considering different userIDClaim
that some of the IdPs are using.
In this PR we read the userIDClaim from the config file
instead of using the fixed default and only keep
it as a fallback if none in defined.
This pull request addresses the need to enhance the installer script by introducing a new parameter --update to trigger updates. The goal is to streamline the update process for binary installations and provide a better experience for users.
The change clarifies the message usage,
indicating that setup keys can alternatively be used
in the authentication process.
This approach adds flexibility in scenarios
where automated authentication is unachievable,
especially in non-desktop Linux environments.
With this fix, all nested slices and pointers will be copied by value.
Also, this fixes tests to compare the original and copy account by their
values by marshaling them to JSON strings.
Before that, they were copying the pointers that also passed the simple `=` compassion
(as the addresses match).
For better auditing this PR adds a dashboard login event to the management service.
For that the user object was extended with a field for last login that is not actively saved to the database but kept in memory until next write. The information about the last login can be extracted from the JWT claims nb_last_login. This timestamp will be stored and compared on each API request. If the value changes we generate an event to inform about a login.
For peer propagation this commit triggers
network map update in two cases:
1) peer login
2) user AutoGroups update
Also it issues new activity message about new user group
for peer login process.
Previous implementation only adds JWT groups to user. This fix also
removes JWT groups from user auto assign groups.
Pelase note, it also happen when user works with dashboard.
Switches the order of initialization in the OAuth flow within
the NewOAuthFlow method. Instead of initializing the
Device Authorization Flow first, it now initializes
the PKCE Authorization Flow first, and falls back
to the Device Authorization Flow if the PKCE initialization fails.
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
In case of 'always-on' feature has switched on, after the reboot the service do not start properly in all cases.
If the device is in offline state (no internet connection) the auth login steps will fail and the service will stop.
For the auth steps make no sense in this case because if the OS start the service we do not have option for
the user interaction.
Enhancements to Peer Group Assignment:
1. Auto-assigned groups are now applied to all peers every time a user logs into the network.
2. Feature activation is available in the account settings.
3. API modifications included to support these changes for account settings updates.
4. If propagation is enabled, updates to a user's auto-assigned groups are immediately reflected across all user peers.
5. With the JWT group sync feature active, auto-assigned groups are forcefully updated whenever a peer logs in using user credentials.
* Move ebpf code to its own package to avoid crash issues in Android
Older versions of android crashes because of the bytecode files
Even when they aren't loaded as it was our case
* move c file to own folder
* fix lint
