.TH CHECKMODULE 8
|
|
.SH NAME
|
|
checkmodule \- SELinux policy module compiler
|
|
.SH SYNOPSIS
|
|
.B checkmodule
|
|
.I "[-h] [-b] [-m] [-M] [-U handle_unknown ] [-V] [-o output_file] [input_file]"
|
|
.SH "DESCRIPTION"
|
|
This manual page describes the
|
|
.BR checkmodule
|
|
command.
|
|
.PP
|
|
.B 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.
|
|
|
|
.SH OPTIONS
|
|
.TP
|
|
.B \-b,\-\-binary
|
|
Read an existing binary policy module file rather than a source policy
|
|
module file. This option is a development/debugging aid.
|
|
.TP
|
|
.B \-h,\-\-help
|
|
Print usage.
|
|
.TP
|
|
.B \-m
|
|
Generate a non-base policy module.
|
|
.TP
|
|
.B \-M,\-\-mls
|
|
Enable the MLS/MCS support when checking and compiling the policy module.
|
|
.TP
|
|
.B \-V,\-\-version
|
|
Show policy versions created by this program. Note that you cannot currently build older versions.
|
|
.TP
|
|
.B \-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.
|
|
.TP
|
|
.B \-U,\-\-handle-unknown <action>
|
|
Specify how the kernel should handle unknown classes or permissions (deny, allow or reject).
|
|
|
|
.SH EXAMPLE
|
|
.nf
|
|
# Build a MLS/MCS-enabled non-base policy module.
|
|
$ checkmodule -M -m httpd.te -o httpd.mod
|
|
.fi
