CHECKMODULE(8)              System Manager's Manual             CHECKMODULE(8)

NAME
       checkmodule - SELinux policy module compiler

SYNOPSIS
       checkmodule  [-h] [-b] [-c policy_version] [-C] [-E] [-m] [-M] [-N] [-U
       handle_unknown] [-V] [-o output_file] [input_file]

DESCRIPTION
       This manual page describes the checkmodule command.

       checkmodule is a program that checks and compiles  a  SELinux  security
       policy  module  into a binary representation.  It can generate either a
       base policy module (default) or a non-base policy module  (-m  option);
       typically, you would build a non-base policy module to add to an exist-
       ing module store that already has a base module provided  by  the  base
       policy.   Use  semodule_package(8)  to combine this module with its op-
       tional file contexts to create a policy package, and  then  use  semod-
       ule(8) to install the module package into the module store and load the
       resulting policy.

OPTIONS
       -b,--binary
              Read an existing binary policy module file rather than a  source
              policy module file.  This option is a development/debugging aid.

       -C,--cil
              Write CIL policy file rather than binary policy file.

       -E,--werror
              Treat warnings as errors

       -h,--help
              Print usage.

       -m     Generate a non-base policy module.

       -M,--mls
              Enable  the MLS/MCS support when checking and compiling the pol-
              icy module.

       -N,--disable-neverallow
              Do not check neverallow rules.

       -V,--version
              Show policy versions created by this program.

       -o,--output filename
              Write a binary policy module file  to  the  specified  filename.
              Otherwise,  checkmodule will only check the syntax of the module
              source file and will not generate a binary module at all.

       -U,--handle-unknown <action> 
              Specify how the kernel should handle unknown classes or  permis-
              sions (deny, allow or reject).

       -c policyvers
              Specify the policy version, defaults to the latest.

EXAMPLE
       # Build a MLS/MCS-enabled non-base policy module.
       $ checkmodule -M -m httpd.te -o httpd.mod
