cachefilesd_selinux(8)	  SELinux Policy cachefilesd	cachefilesd_selinux(8)

NAME
       cachefilesd_selinux   -	 Security   Enhanced   Linux  Policy  for  the
       cachefilesd processes

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

       The  cachefilesd processes execute with the cachefilesd_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 cachefilesd_t

ENTRYPOINTS
       The    cachefilesd_t    SELinux	 type	can   be   entered   via   the
       cachefilesd_exec_t file type.

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

       /sbin/cachefilesd, /usr/sbin/cachefilesd

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
       cachefilesd  policy  is	very  flexible	allowing  users to setup their
       cachefilesd processes in as secure a method as possible.

       The following process types are defined for cachefilesd:

       cachefilesd_t, cachefiles_kernel_t

       Note: semanage permissive -a cachefilesd_t can  be  used	 to  make  the
       process	type cachefilesd_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.
       cachefilesd policy is extremely flexible and has several booleans  that
       allow  you to manipulate the policy and run cachefilesd with the tight‐
       est access possible.

       If you want to allow all daemons to write corefiles to /, you must turn
       on the daemons_dump_core boolean. Disabled by default.

       setsebool -P daemons_dump_core 1

       If  you	want  to enable cluster mode for daemons, you must turn on the
       daemons_enable_cluster_mode boolean. Enabled by default.

       setsebool -P daemons_enable_cluster_mode 1

       If you want to allow all daemons to use tcp wrappers, you must turn  on
       the daemons_use_tcp_wrapper boolean. Disabled by default.

       setsebool -P daemons_use_tcp_wrapper 1

       If  you	want to allow all daemons the ability to read/write terminals,
       you must turn on the daemons_use_tty boolean. Disabled by default.

       setsebool -P daemons_use_tty 1

       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 cachefilesd_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.

       cachefiles_var_t

	    /var/fscache(/.*)?
	    /var/cache/fscache(/.*)?

       cachefilesd_var_run_t

	    /var/run/cachefilesd.pid

       cluster_conf_t

	    /etc/cluster(/.*)?

       cluster_var_lib_t

	    /var/lib/pcsd(/.*)?
	    /var/lib/cluster(/.*)?
	    /var/lib/openais(/.*)?
	    /var/lib/pengine(/.*)?
	    /var/lib/corosync(/.*)?
	    /usr/lib/heartbeat(/.*)?
	    /var/lib/heartbeat(/.*)?
	    /var/lib/pacemaker(/.*)?

       cluster_var_run_t

	    /var/run/crm(/.*)?

	    /var/run/rsctmp(/.*)?
	    /var/run/aisexec.*
	    /var/run/heartbeat(/.*)?
	    /var/run/cpglockd.pid
	    /var/run/corosync.pid
	    /var/run/rgmanager.pid
	    /var/run/cluster/rgmanager.sk

       root_t

	    /
	    /initrd

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 cachefilesd policy is very flexible  allowing  users  to	 setup
       their cachefilesd processes in as secure a method as possible.

       STANDARD FILE CONTEXT

       SELinux	defines	 the  file  context  types for the cachefilesd, 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  cachefilesd_exec_t	'/srv/cachefilesd/con‐
       tent(/.*)?'
       restorecon -R -v /srv/mycachefilesd_content

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

       The following file types are defined for cachefilesd:

       cachefilesd_exec_t

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

       Paths:
	    /sbin/cachefilesd, /usr/sbin/cachefilesd

       cachefilesd_var_run_t

       -  Set  files with the cachefilesd_var_run_t type, if you want to store
       the cachefilesd files under the /run or /var/run directory.

       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.
