semodule — Manage SELinux policy modules.

Synopsis

semodule [options]... MODE [MODES]...

Description

semodule is the tool used to manage SELinux policy modules, including installing, upgrading, listing and removing modules.   semodule may also be used to force a rebuild of policy from the module store and/or to force a reload of policy without performing any other transaction.  semodule acts on module packages created by semodule_package.  Conventionally, these files have a .pp suffix (policy package), although this is not mandated in any way.

Options

-R, --reload

force a reload of policy

-B, --build

force a rebuild of policy (also reloads unless -n is used)

-D, --disable_dontaudit

Temporarily remove dontaudits from policy.  Reverts whenever policy is rebuilt

-i,--install=MODULE_PKG

install/replace a module package

-u,--upgrade=MODULE_PKG

deprecated, alias for --install

-b,--base=MODULE_PKG

deprecated, alias for --install

-r,--remove=MODULE_NAME

remove existing module

-l[KIND],--list-modules[=KIND]

display list of installed modules (other than base)

-E,--extract=MODULE_PKG

Extract a module from the store as an HLL or CIL file to the current directory. A module is extracted as HLL by default. The name of the module written is <module-name>.<lang_ext>

KIND:
standard

list highest priority, enabled, non-base modules

full

list all modules

-X,--priority=PRIORITY

set priority for following operations (1-999)

-e,--enabled=MODULE_NAME

enable module

-d,--disable=MODULE_NAME

disable module

-s,--store

name of the store to operate on

-n,--noreload,-N

do not reload policy after commit

-h,--help

prints help message and quit

-P,--preserve_tunables

Preserve tunables in policy

-C,--ignore-module-cache

Recompile CIL modules built from HLL files

-p,--path

Use an alternate path for the policy root

-S,--store-path

Use an alternate path for the policy store root

-v,--verbose

be verbose

-c,--cil

Extract module as a CIL file. This only affects the --extract option and only modules listed in --extract after this option.

-H,--hll

Extract module as an HLL file. This only affects the --extract option and only modules listed in --extract after this option.

Example

# Install or replace a base policy package.
$ semodule -b base.pp
# Install or replace a non-base policy package.
$ semodule -i httpd.pp
# List non-base modules.
$ semodule -l
# Turn on all AVC Messages for which SELinux currently is "dontaudit"ing.
$ semodule -DB
# Turn "dontaudit" rules back on.
$ semodule -B
# Install or replace all non-base modules in the current directory.
$ semodule -i *.pp
# Install or replace all modules in the current directory.
$ ls *.pp | grep -Ev "base.pp|enableaudit.pp" | xargs /usr/sbin/semodule -b base.pp -i
# Disable a module.
$ semodule -d alsa
# Install a module at a specific priority.
$ semodule -X 100 -i alsa.pp
# List all modules.
$ semodule --list=full
# Set an alternate path for the policy root
$ semodule -B -p "/tmp"
# Set an alternate path for the policy store root
$ semodule -B -S "/tmp/var/lib/selinux"
# Write the HLL version of puppet and the CIL version of wireshark
# modules at priority 400 to the current working directory
$ semodule -X 400 --hll -E puppet --cil -E wireshark
