NAME checkpolicy - SELinux policy compiler

SYNOPSIS checkpolicy [-b] [-d] [-M] [-U handle_unknown ] [-V] [-c policyvers] [-o output_file] [input_file]

DESCRIPTION This manual page describes the checkpolicy command.

checkpolicy is a program that checks and compiles a SELinux security policy configuration into a binary representation that can be loaded into the kernel. If no input file name is specified, checkpolicy will attempt to read from policy.conf or policy, depending on whether the -b flag is specified.

OPTIONS -b Read an existing binary policy file rather than a source pol- icy.conf file.

-d Enter debug mode after loading the policy.

-M Enable the MLS policy when checking and compiling the policy.

-o filename Write a binary policy file to the specified filename.

-c policyvers Specify the policy version, defaults to the latest.

-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
