NAME

6       checkmodule - SELinux policy module compiler

SYNOPSIS

9       checkmodule [-h] [-b] [-C] [-m] [-M] [-U handle_unknown ] [-V] [-o out‐
10       put_file] [input_file]

DESCRIPTION

13       This manual page describes the checkmodule command.
14
15       checkmodule is a program that checks and compiles  a  SELinux  security
16       policy  module  into a binary representation.  It can generate either a
17       base policy module (default) or a non-base policy module  (-m  option);
18       typically, you would build a non-base policy module to add to an exist‐
19       ing module store that already has a base module provided  by  the  base
20       policy.   Use semodule_package to combine this module with its optional
21       file contexts to create a policy package,  and  then  use  semodule  to
22       install the module package into the module store and load the resulting
23       policy.

OPTIONS

27       -b,--binary
28              Read an existing binary policy module file rather than a  source
29              policy module file.  This option is a development/debugging aid.
30
31       -C,--cil
32              Write CIL policy file rather than binary policy file.
33
34       -E,--werror
35              Treat warnings as errors
36
37       -h,--help
38              Print usage.
39
40       -m     Generate a non-base policy module.
41
42       -M,--mls
43              Enable  the MLS/MCS support when checking and compiling the pol‐
44              icy module.
45
46       -V,--version
47              Show policy versions created by this program.
48
49       -o,--output filename
50              Write a binary policy module file  to  the  specified  filename.
51              Otherwise,  checkmodule will only check the syntax of the module
52              source file and will not generate a binary module at all.
53
54       -U,--handle-unknown <action>
55              Specify how the kernel should handle unknown classes or  permis‐
56              sions (deny, allow or reject).
57
58       -c policyvers
59              Specify the policy version, defaults to the latest.

EXAMPLE
