NAME
       semodule - Manage SELinux policy modules.

SYNOPSIS
       semodule [option]... MODE...
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.  Conven-
       tionally, these files have a .pp suffix (policy package), although this
       is not mandated in any way.

MODES
       -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 at desired priority (defaults to -X 400)
       -l[KIND],--list-modules[=KIND]
              display list of installed modules (other than base)
       KIND:
       standard
              list highest priority, enabled, non-base modules
       full   list all modules
       -X,--priority=PRIORITY
              set priority for following operations (1-999)
       -e,--enable=MODULE_NAME
              enable module
       -d,--disable=MODULE_NAME
              disable module
       -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>
OPTIONS
       -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
       # Install or replace all non-base modules in the current directory.
       # This syntax can be used with -i/u/r/E, but no other option can be entered after the module names
       $ 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
       # List non-base modules.
       $ semodule -l
       # List all modules including priorities
       $ semodule -lfull
       # Remove a module at priority 100
       $ semodule -X 100 -r wireshark
       # Turn on all AVC Messages for which SELinux currently is "dontaudit"ing.
       $ semodule -DB
       # Turn "dontaudit" rules back on.
       $ semodule -B
       # Disable a module (all instances of given module across priorities will be disabled).
       $ 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
