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

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

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

       -C,--cil
              Write CIL policy file rather than binary policy file.

       -d,--debug
              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).

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

       -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.

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

       -t,--target
              Specify the target platform (selinux or xen).

       -O,--optimize
              Optimize the final kernel policy (remove redundant rules).

       -E,--werror
              Treat warnings as errors

       -V,--version
              Show version information.

       -h,--help
              Show usage information.
