SEMODULE(8)                                              NSA                                              SEMODULE(8)



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

       -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
