# How To Contribute

## Linux

The DCO implementation on Linux is a kernel module called _ovpn_.

_ovpn_ has been merged in the Linux mainline repository and it's part of the
offical kernel release since version 6.16.

For this reason all new features and bug-fixes must follow the Linux kernel
development process and patches must adhere to the Linux kernel CodingStyle.

All patches for _ovpn_ are collected in the `ovpn-net-next` repository and then
submitted to the Linux networking tree by the _ovpn_ maintainer (Antonio Quartulli
at the time of writing).

### Branches

To follow the Linux kernel development process, the `ovpn-net-next` repository
provides 2 branches, namely `main` and `net`, which respectively track the upstream
`net-next` and `net` tree.

Developers willing to send new features should based their changes on the `main` branch,
while for bug fixes they should use `net`.

### Sending patches

New patches for _ovpn_, being them new features or bug-fixes, should be sent to the
openvpn-devel mailing list witht the specific subject `[PATCH ovpn-net-next]`, so that
they can be picked up accordingly.
