NAME
       checkpolicy_selinux  - Security Enhanced Linux Policy for the checkpol‐
       icy processes

DESCRIPTION
       Security-Enhanced Linux secures the checkpolicy processes via  flexible
       mandatory access control.

       The  checkpolicy processes execute with the checkpolicy_t SELinux type.
       You can check if you have these processes running by executing  the  ps
       command with the -Z qualifier.

       For example:

       ps -eZ | grep checkpolicy_t

ENTRYPOINTS
       The  checkpolicy_t  SELinux  type  can  be  entered  via	 the checkpol‐
       icy_exec_t file type.

       The default entrypoint paths for the checkpolicy_t domain are the  fol‐
       lowing:

       /usr/bin/checkpolicy

PROCESS TYPES
       SELinux defines process types (domains) for each process running on the
       system

       You can see the context of a process using the -Z option to ps

       Policy governs the access confined processes have  to  files.   SELinux
       checkpolicy  policy  is	very  flexible	allowing  users to setup their
       checkpolicy processes in as secure a method as possible.

       The following process types are defined for checkpolicy:

       checkpolicy_t

       Note: semanage permissive -a checkpolicy_t can  be  used	 to  make  the
       process	type checkpolicy_t permissive. SELinux does not deny access to
       permissive process types, but the AVC (SELinux  denials)	 messages  are
       still generated.

BOOLEANS
       SELinux	policy is customizable based on least access required.	check‐
       policy policy is extremely flexible and has several booleans that allow
       you  to	manipulate  the	 policy	 and run checkpolicy with the tightest
       access possible.

       If you want to deny any process from ptracing or	 debugging  any	 other
       processes,  you	must  turn  on	the  deny_ptrace  boolean.  Enabled by
       default.

       setsebool -P deny_ptrace 1

       If you want to allow all domains to use other domains file descriptors,
       you must turn on the domain_fd_use boolean. Enabled by default.

       setsebool -P domain_fd_use 1

       If  you	want to allow all domains to have the kernel load modules, you
       must  turn  on  the  domain_kernel_load_modules	boolean.  Disabled  by
       default.

       setsebool -P domain_kernel_load_modules 1

       If you want to allow all domains to execute in fips_mode, you must turn
       on the fips_mode boolean. Enabled by default.

       setsebool -P fips_mode 1

       If you want to enable reading of urandom for all domains, you must turn
       on the global_ssp boolean. Disabled by default.

       setsebool -P global_ssp 1

MANAGED FILES
       The  SELinux  process  type checkpolicy_t can manage files labeled with
       the following file types.  The paths listed are the default  paths  for
       these  file  types.  Note the processes UID still need to have DAC per‐
       missions.

       semanage_store_t

	    /etc/selinux/([^/]*/)?policy(/.*)?
	    /etc/selinux/([^/]*/)?modules/(active|tmp|previous)(/.*)?
	    /etc/share/selinux/mls(/.*)?
	    /etc/share/selinux/targeted(/.*)?

FILE CONTEXTS
       SELinux requires files to have an extended attribute to define the file
       type.

       You can see the context of a file using the -Z option to ls

       Policy  governs	the  access  confined  processes  have to these files.
       SELinux checkpolicy policy is very flexible  allowing  users  to	 setup
       their checkpolicy processes in as secure a method as possible.

       STANDARD FILE CONTEXT

       SELinux	defines	 the  file  context  types for the checkpolicy, if you
       wanted to store files with these types in a diffent paths, you need  to
       execute	the  semanage  command to sepecify alternate labeling and then
       use restorecon to put the labels on disk.

       semanage	 fcontext  -a  -t  checkpolicy_exec_t	'/srv/checkpolicy/con‐
       tent(/.*)?'
       restorecon -R -v /srv/mycheckpolicy_content

       Note:  SELinux  often  uses  regular expressions to specify labels that
       match multiple files.

       The following file types are defined for checkpolicy:

       checkpolicy_exec_t

       - Set files with the checkpolicy_exec_t type, if you want to transition
       an executable to the checkpolicy_t domain.

       Note:  File context can be temporarily modified with the chcon command.
       If you want to permanently change the file context you need to use  the
       semanage fcontext command.  This will modify the SELinux labeling data‐
       base.  You will need to use restorecon to apply the labels.

COMMANDS
       semanage fcontext can also be used to manipulate default	 file  context
       mappings.

       semanage	 permissive  can  also	be used to manipulate whether or not a
       process type is permissive.

       semanage module can also be used to enable/disable/install/remove  pol‐
       icy modules.

       semanage boolean can also be used to manipulate the booleans

       system-config-selinux is a GUI tool available to customize SELinux pol‐
       icy settings.
