CHECKMODULE(8)                                                                                                    CHECKMODULE(8)



NAME
       checkmodule - SELinux policy module compiler

SYNOPSIS
       checkmodule [-h] [-b] [-m] [-M] [-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 existing module store that already has a base module provided by the base policy.  Use
       semodule_package to combine this module with its optional file contexts to create a policy package, and then use semodule
       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 develop-
              ment/debugging aid.

       -h,--help
              Print usage.

       -m     Generate a non-base policy module.

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

       -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 permissions (deny, allow or reject).


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