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.
       Conventionally,  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)

       --refresh
              Like --build, but reuses existing linked policy if no changes to module  files  are
              detected  (by comparing with checksum from the last transaction).  One can use this
              instead of -B to ensure that any changes to the module store done  by  an  external
              tool  (e.g. a package manager) are applied, while automatically skipping the module
              re-linking if there are no module changes.

       -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.

       -m,--checksum
              Add SHA256 checksum of modules to the list output.

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
       # Check whether a module in "localmodule.pp" file is same as installed module "localmodule"
       $ /usr/libexec/selinux/hll/pp localmodule.pp | sha256sum
       $ semodule -l -m | grep localmodule
