SELinux is a flexible Mandatory Access Control (MAC) system built into the Linux Kernel. SELinux provides administrators with a comprehensive access control mechanism that enables greater access granularity over the existing Linux Discretionary Access Controls (DAC) and is present in many major Linux distributions. This repository contains the sources for the SELinux utilities and system libraries which allow for the configuration and management of an SELinux-based system.
Please submit all bug reports and patches to the selinux@vger.kernel.org mailing list. You can subscribe by sending “subscribe selinux” in the body of an email to majordomo@vger.kernel.org. Archives of the mailing list are available at https://lore.kernel.org/selinux.
SELinux libraries and tools are packaged in several Linux distributions:
Build dependencies on Fedora:
# For C libraries and programs dnf install \ audit-libs-devel \ bison \ bzip2-devel \ CUnit-devel \ diffutils \ flex \ gcc \ gettext \ glib2-devel \ make \ libcap-devel \ libcap-ng-devel \ pam-devel \ pcre2-devel \ xmlto # For Python and Ruby bindings dnf install \ python3-devel \ python3-pip \ python3-setuptools \ python3-wheel \ ruby-devel \ swig
Build dependencies on Debian:
# For C libraries and programs apt-get install --no-install-recommends --no-install-suggests \ bison \ flex \ gawk \ gcc \ gettext \ make \ libaudit-dev \ libbz2-dev \ libcap-dev \ libcap-ng-dev \ libcunit1-dev \ libglib2.0-dev \ libpcre2-dev \ pkgconf \ python3 \ systemd \ xmlto # For Python and Ruby bindings apt-get install --no-install-recommends --no-install-suggests \ python3-dev \ python3-pip \ python3-setuptools \ python3-wheel \ ruby-dev \ swig
To build and install everything under a private directory, run:
make clean distclean make DESTDIR=~/obj install install-rubywrap install-pywrap
On Debian the environment variable DEB_PYTHON_INSTALL_LAYOUT
needs to be set to deb
when installing the Python wrappers in order to create the correct Python directory structure. On Debian systems older than bookworm set PYTHON_SETUP_ARGS='--install-option "--install-layout=deb"'
instead.
To run tests with the built libraries and programs, several paths (relative to $DESTDIR
) need to be added to variables $LD_LIBRARY_PATH
, $PATH
and $PYTHONPATH
. This can be done using ./scripts/env_use_destdir:
DESTDIR=~/obj ./scripts/env_use_destdir make test
Some tests require the reference policy to be installed (for example in python/sepolgen
).
To install as the default system libraries and binaries (overwriting any previously installed ones - dangerous!), on x86_64, run:
make LIBDIR=/usr/lib64 SHLIBDIR=/lib64 install install-pywrap relabel
or on x86 (32-bit), run:
make install install-pywrap relabel
This may render your system unusable if the upstream SELinux userspace lacks library functions or other dependencies relied upon by your distribution. If it breaks, you get to keep both pieces.
Setting CFLAGS during the make process will cause the omission of many defaults. While the project strives to provide a reasonable set of default flags, custom CFLAGS could break the build, or have other undesired changes on the build output. Thus, be very careful when setting CFLAGS. CFLAGS that are encouraged to be set when overriding are:
To install libsepol on macOS (mainly for policy analysis):
cd libsepol; make PREFIX=/usr/local install
This requires GNU coreutils:
brew install coreutils
