cpufreqselector_selinux(SELinux Policy cpufreqselectcpufreqselector_selinux(8)NAMEcpufreqselector_selinux - Security Enhanced Linux Policy for the
Security-Enhanced Linux secures the cpufreqselector processes via flex‐
ible mandatory access control.
The cpufreqselector processes execute with the cpufreqselector_t
SELinux type. You can check if you have these processes running by exe‐
cuting the ps command with the -Z qualifier.
ps -eZ | grep cpufreqselector_t
The cpufreqselector_t SELinux type can be entered via the cpufreqselec‐
tor_exec_t file type.
The default entrypoint paths for the cpufreqselector_t domain are the

cpufreqselector policy is very flexible allowing users to setup their
cpufreqselector processes in as secure a method as possible.
The following process types are defined for cpufreqselector:
Note: semanage permissive -a cpufreqselector_t can be used to make the
process type cpufreqselector_t permissive. SELinux does not deny access
to permissive process types, but the AVC (SELinux denials) messages are
SELinux policy is customizable based on least access required. cpufre‐
qselector policy is extremely flexible and has several booleans that
allow you to manipulate the policy and run cpufreqselector with the
tightest 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
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 cpufreqselector_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
SELinux requires files to have an extended attribute to define the file
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 cpufreqselector policy is very flexible allowing users to setup
their cpufreqselector processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the cpufreqselector, 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 cpufreqselector_exec_t '/srv/cpufreqselec‐
restorecon -R -v /srv/mycpufreqselector_content
Note: SELinux often uses regular expressions to specify labels that
match multiple files.
The following file types are defined for cpufreqselector:
- Set files with the cpufreqselector_exec_t type, if you want to tran‐
sition an executable to the cpufreqselector_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.
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‐
semanage boolean can also be used to manipulate the booleans
