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
