NAME
checkmodule − SELinux policy module compiler
SYNOPSIS
checkmodule [−h] [−b] [−c policy_version] [−C] [−E] [−m] [−M] [−N] [−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.
−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.
EXAMPLE
Build a MLS/MCS-enabled non-base policy module.
$ checkmodule −M −m httpd.te −o httpd.mod
