NAME

       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
