       checkmodule - SELinux policy module compiler


       checkmodule   [-h]  [-b]  [-m]  [-M]  [-U  handle_unknown  ]  [-V]  [-o
       output_file] [input_file]


       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.


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

              Print usage.

       -m     Generate a non-base policy module.

              Enable  the  MLS/MCS  support  when  checking  and compiling the
              policy module.

               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).
