checkmodule - SELinux policy module compiler


checkmodule [-h] [-b] [-C] [-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,--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. -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. -V,--version Show policy versions created by this program. Note that you cannot currently build older versions. -o,--output filename Write a binary policy module file to the specified filename. Otherwise, checkmod‐ ule 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).
