       cachefiles_kernel_selinux  -  Security  Enhanced	 Linux	Policy for the
       cachefiles_kernel processes

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

       The  cachefiles_kernel  processes  execute with the cachefiles_kernel_t
       SELinux type. You can check if you have these processes running by exe‐
       cuting the ps command with the -Z qualifier.

       For example:

       ps -eZ | grep cachefiles_kernel_t

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

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

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

       The following process types are defined for cachefiles_kernel:


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

       SELinux	 policy	 is  customizable  based  on  least  access  required.
       cachefiles_kernel policy is extremely flexible and has several booleans
       that  allow you to manipulate the policy and run cachefiles_kernel 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

       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

       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

       The  SELinux  process type cachefiles_kernel_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



       semanage fcontext can also be used to manipulate default	 file  context

       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.
