CHECKMODULE(8)CHECKMODULE(8)NAMEcheckmodule - SELinux policy module compiler
SYNOPSIScheckmodule [-b] [-m] [-M] [-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 exist‐
ing 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,--binary
Read an existing binary policy module file rather than a source
policy module file. This option is a development/debugging aid.
-m Generate a non-base policy module.
-M,--mls
Enable the MLS/MCS support when checking and compiling the pol‐
icy module.
-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 permis‐
sions (deny, allow or reject).
EXAMPLE
# Build a MLS/MCS-enabled non-base policy module.
$ checkmodule-M -m httpd.te -o httpd.mod
