CHECKMODULE(8)                                                  CHECKMODULE(8)



NAME
       checkmodule - SELinux policy module compiler

SYNOPSIS
       checkmodule [-b] [-d] [-m] [-M] [-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 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     Read  an existing binary policy module file rather than a source
              policy module file.  This option is a development/debugging aid.

       -d     Enter  debug  mode  after  loading the policy.  This option is a
              development/debugging aid.

       -m     Generate a non-base policy module.

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

       -o 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.


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