Security Enhanced Linux Policy for the kernel_systemctl processes


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

The kernel_systemctl processes execute with the kernel_systemctl_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 kernel_systemctl_t


The kernel_systemctl_t SELinux type can be entered via the systemd_systemctl_exec_t file type.

The default entrypoint paths for the kernel_systemctl_t domain are the following:

/bin/systemctl, /usr/bin/systemctl

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 psbP

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

The following process types are defined for kernel_systemctl:


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


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

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

Managed Files

The SELinux process type kernel_systemctl_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.




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 policy modules.

semanage boolean can also be used to manipulate the booleans

system-config-selinux is a GUI tool available to customize SELinux policy settings.
