NAME

checkpolicy - SELinux policy compiler

SYNOPSIS

checkpolicy [-b[F]] [-C] [-d] [-U handle_unknown (allow,deny,reject)] [-M] [-N] [-c policyvers] [-o output_file|-] [-S] [-t target_platform (selinux,xen)] [-O] [-E] [-V] [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,--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.
-N,--disable-neverallow: Do not check neverallow rules.
-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.

EXAMPLE

Generate policy.conf based on the system policy
# checkpolicy -b -M -F /etc/selinux/targeted/policy/policy.33 -o policy.conf
Recompile system policy so that unknown permissions are denied (uses policy.conf from ^^).
Note that binary policy extension represents its version, which is subject to change
# checkpolicy -M -U deny -o /etc/selinux/targeted/policy/policy.33 policy.conf
# load_policy
Generate CIL representation of current system policy
# checkpolicy -b -M -C /etc/selinux/targeted/policy/policy.33 -o policy.out
