Contributing to the SELinux userspace project is a similar process to other open source projects. Bug reports, new features to the existing code, additional tools, or updated documentation are all welcome.
You can find a list of open issues to the SELinux userspace code at https://github.com/SELinuxProject/selinux/issues
See the SELinux kernel Getting Started guide if you want to contribute to SELinux kernel development instead.
SELinux has a public mailing list for developers, subscribe by sending an email to selinux+subscribe@vger.kernel.org. It is generally wise to read relevant postings to the list before beginning any area of new work. Searchable mailing list archives are available externally at https://lore.kernel.org/selinux/ . Patches for SELinux are tracked via https://patchwork.kernel.org/project/selinux/list/ .
An unofficial SELinux IRC channel is #selinux on Libera.Chat.
All bugs and patches should be submitted to the SELinux mailing list at selinux@vger.kernel.org.
When reporting bugs please include versions of SELinux related libraries and tools (libsepol, libselinux, libsemanage, checkpolicy). If you are using a custom policy please include it as well.
There are a number of dependencies required to build the userspace tools/libraries. Consult the README.md for the current list of dependencies and how to build the userspace code.
After cloning the code of the repository (see below), create a patch against the repository, and post that patch to the SELinux mailing list at selinux@vger.kernel.org. When preparing patches, please follow these guidelines:
- Patches should apply with git am
- Must apply against HEAD of the main branch
- Separate large patches into logical patches
- Patch descriptions must end with your "Signed-off-by" line. This means your code meets the Developer's certificate of origin, see below.
When adding new, large features or tools it is best to discuss the design on the mailing list prior to submitting the patch.
To get a copy of the SELinux userland repository you can run:
$ git clone https://github.com/SELinuxProject/selinux.git
