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

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

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.
Specify how the kernel should handle unknown classes or permissions (deny, allow or reject).
Enable the MLS policy when checking and compiling the policy.
Do not check neverallow rules.
Specify the policy version, defaults to the latest.
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
Show version information.
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
