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
