CHECKPOLICY(8)           System Manager's Manual          CHECKPOLICY(8)

NAME         top

       checkpolicy - SELinux policy compiler

SYNOPSIS         top

       checkpolicy [-b[F]] [-C] [-d] [-U handle_unknown
       (allow,deny,reject)] [-M] [-c policyvers] [-o output_file|-] [-S]
       [-t target_platform (selinux,xen)] [-O] [-E] [-V] [input_file]

DESCRIPTION         top

       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         top

              Read an existing binary policy file rather than a source
              policy.conf file.

              Write policy.conf file rather than binary policy file. Can
              only be used with binary policy file.

              Write CIL policy file rather than binary policy file.

              Enter debug mode after loading the policy.

       -U,--handle-unknown <action>
              Specify how the kernel should handle unknown classes or
              permissions (deny, allow or reject).

              Enable the MLS policy when checking and compiling the

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

       -o,--output filename
              Write a policy file (binary, policy.conf, or CIL policy)
              to the specified filename. If - is given as filename,
              write it to standard output.

              Sort ocontexts before writing out the binary policy. This
              option makes output of checkpolicy consistent with binary
              policies created by semanage and secilc.

              Specify the target platform (selinux or xen).

              Optimize the final kernel policy (remove redundant rules).

              Treat warnings as errors
