checkmodule - Man Page

checkmodule [-h] [-b] [-c policy_version] [-C] [-E] [-m] [-M] [-N] [-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(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.

-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.

-N,--disable-neverallow

Do not check neverallow rules.

-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.

# Build a MLS/MCS-enabled non-base policy module.
