.SH "DESCRIPTION"
|
|
This manual page describes the
|
|
.BR checkpolicy
|
|
command.
|
|
.PP
|
|
.B 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,
|
|
.B checkpolicy
|
|
will attempt to read from policy.conf or policy, depending on whether the \-b
|
|
flag is specified.
|
|
|
|
.SH OPTIONS
|
|
.TP
|
|
.B \-b,\-\-binary
|
|
Read an existing binary policy file rather than a source policy.conf file.
|
|
.TP
|
|
.B \-F,\-\-conf
|
|
Write policy.conf file rather than binary policy file. Can only be used with binary policy file.
|
|
.TP
|
|
.B \-C,\-\-cil
|
|
Write CIL policy file rather than binary policy file.
|
|
.TP
|
|
.B \-d,\-\-debug
|
|
Enter debug mode after loading the policy.
|
|
.TP
|
|
.B \-U,\-\-handle-unknown <action>
|
|
Specify how the kernel should handle unknown classes or permissions (deny, allow or reject).
|
|
.TP
|
|
.B \-M,\-\-mls
|
|
Enable the MLS policy when checking and compiling the policy.
|
|
.TP
|
|
.B \-N,\-\-disable-neverallow
|
|
Do not check neverallow rules.
|
|
.TP
|
|
.B \-c policyvers
|
|
Specify the policy version, defaults to the latest.
|
|
.TP
|
|
.B \-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.
|
|
.TP
|
|
.B \-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.
|
|
.TP
|
|
.B \-t,\-\-target
|
|
Specify the target platform (selinux or xen).
|
|
.TP
|
|
.B \-O,\-\-optimize
|
|
Optimize the final kernel policy (remove redundant rules).
|
|
.TP
|
|
.B \-E,\-\-werror
|
|
Treat warnings as errors
|
|
.TP
|
|
.B \-V,\-\-version

|
.B \-h,\-\-help
|
|
Show usage information.

.SH EXAMPLE
|
|
.nf
|
|
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
