checkpolicy - SELinux policy compiler


checkpolicy [-b[F]] [-C] [-d] [-M] [-c policyvers] [-o output_file] [input_file]


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.


Read an existing binary policy file rather than a source policy.conf file.
Write CIL policy file rather than binary policy file.
Enter debug mode after loading the policy.
Write policy.conf file rather than binary policy file. Can only be used with binary policy file.
Enable the MLS policy when checking and compiling the policy.
-o,--output filename
Write a binary policy file to the specified filename.
-c policyvers
Specify the policy version, defaults to the latest.
Specify the target platform (selinux or xen).
-U,--handle-unknown <action>
Specify how the kernel should handle unknown classes or permissions (deny, allow or reject).
Show version information.
Show usage information.
