NAME

   checkmodule - SELinux policy module compiler

SYNOPSIS

   checkmodule  [-h]  [-b]  [-C]  [-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 development/debugging aid.

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

   -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.   Note  that  you
          cannot currently build older versions.

   -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
