checkmodule - SELinux policy module compiler
checkmodule [-b] [-d] [-h] [-m] [-M] [-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 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.
-b Read an existing binary policy module file rather than a source policy module file. This option is a development/debugging aid. -d Enter debug mode after loading the policy. This option is a development/debugging aid. -h Print the usage message. -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.
-U OPTION Tells the kernel how to handle unknown classes and permissions, where OPTION is one of the following:
deny Deny unknown kernel checks
reject Reject loading of policy with unknowns
allow Allow unknown kernel checks
-V Show policy versions created by this program
# Build a MLS/MCS-enabled non-base policy module. $ checkmodule -M -m httpd.te -o httpd.mod
