Contributing to SELinux

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 where you might contribute to the SELinux kernel code at or to the SELinux userspace code at

See the user resources page for more information on mailing lists, documentation, and other resources.

Reporting Bugs

All bugs and patches should be submitted to the SELinux mailing list at

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. On a Fedora system you can install them with yum:

# yum install audit-libs-devel bison bzip2-devel dbus-devel dbus-glib-devel flex flex-devel flex-static glib2-devel libcap-devel libcap-ng-devel pam-devel pcre-devel python-devel setools-devel swig ustr-devel

The tools and libraries can be built and installed under a private directory from the top level with make, e.g.

$ make DESTDIR=~/obj install install-pywrap

Contributing Code

After obtaining the code of the repository (see below), create a patch against the repository, and post that patch to the SELinux mailing list at When preparing patches, please follow these guidelines:

  • Patches should apply with -p1
  • Must apply against HEAD of the master 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.

Development Repository

Git is a modern source code management system. For more information about Git please see the Git website.

To get an anonymous checkout of the SELinux userland repository you can run:

$ git clone
