NAME

       checkmodule - SELinux policy module compiler

SYNOPSIS

       checkmodule  [-h]  [-b] [-c policy_version] [-C] [-E] [-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(8) to combine this module
       with its optional file contexts to create a policy package, and  then  use  semodule(8)  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.

       -E,--werror
              Treat warnings as errors

       -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.

       -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).

       -c policyvers
              Specify the policy version, defaults to the latest.

EXAMPLE

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