NAME
       cpuspeed_selinux - Security Enhanced Linux Policy for the cpuspeed pro‐
       cesses

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

       The  cpuspeed  processes	 execute with the cpuspeed_t SELinux type. You
       can check if you have these processes running by executing the ps  com‐
       mand with the -Z qualifier.

       For example:

       ps -eZ | grep cpuspeed_t

ENTRYPOINTS
       The cpuspeed_t SELinux type can be entered via the cpuspeed_exec_t file
       type.

       The default entrypoint paths for the cpuspeed_t domain are the  follow‐
       ing:

       /usr/sbin/cpufreqd, /usr/sbin/cpuspeed, /usr/sbin/powernowd

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

       The following process types are defined for cpuspeed:

       cpuspeed_t

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

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

       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

       If you want to allow confined applications to use nscd  shared  memory,
       you must turn on the nscd_use_shm boolean. Disabled by default.

       setsebool -P nscd_use_shm 1

MANAGED FILES
       The  SELinux  process type cpuspeed_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 permissions.

       cpuspeed_var_run_t

	    /var/run/cpufreqd.pid

       sysfs_t

	    /sys(/.*)?

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

       STANDARD FILE CONTEXT

       SELinux defines the file context types for the cpuspeed, 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 cpuspeed_exec_t '/srv/cpuspeed/content(/.*)?'
       restorecon -R -v /srv/mycpuspeed_content

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

       The following file types are defined for cpuspeed:

       cpuspeed_exec_t

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

       Paths:
	    /usr/sbin/cpufreqd, /usr/sbin/cpuspeed, /usr/sbin/powernowd

       cpuspeed_var_run_t

       -  Set files with the cpuspeed_var_run_t type, if you want to store the
       cpuspeed 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.
