NAME

checkmodule - SELinux policy module compiler  

SYNOPSIS

checkmodule [-b] [-m] [-M] [-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
Read an existing binary policy module file rather than a source policy module file. This option is a development/debugging aid.
-m
Generate a non-base policy module.
-M
Enable the MLS/MCS support when checking and compiling the policy module.
-V

 Show policy versions created by this program
-o 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.

 

EXAMPLE

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