CHECKMODULE(8) CHECKMODULE(8)

NAME checkmodule - SELinux policy module compiler

SYNOPSIS checkmodule [-b] [-d] [-m] [-M] [-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 mod- ule file. This option is a development/debugging aid.

-d Enter debug mode after loading the policy. This option is a develop- ment/debugging aid.

-m Generate a non-base policy module.

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

-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 $ checkmodule -M -m httpd.te -o httpd.mod
