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 development/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.   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
