CHECKMODULE(8)              System Manager's Manual             CHECKMODULE(8)
NAME
       checkmodule - SELinux policy module compiler
SYNOPSIS
       checkmodule [-h] [-b] [-C] [-m] [-M] [-U handle_unknown ] [-V] [-o out-
       put_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,--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 pol-
              icy 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 permis-
              sions (deny, allow or reject).
EXAMPLE
       # Build a MLS/MCS-enabled non-base policy module.
       $ checkmodule -M -m httpd.te -o httpd.mod
