dlm_controld_selinux(8) - Linux man page

Name

dlm_controld_selinux - Security Enhanced Linux Policy for the dlm_controld processes

Description

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

The dlm_controld processes execute with the dlm_controld_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 dlm_controld_t

Entrypoints

The dlm_controld_t SELinux type can be entered via the "dlm_controld_exec_t" file type. The default entrypoint paths for the dlm_controld_t domain are the following:"

/usr/sbin/dlm_controld

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

The following process types are defined for dlm_controld:

dlm_controld_t

Note: semanage permissive -a dlm_controld_t

can be used to make the process type dlm_controld_t permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.

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

The following file types are defined for dlm_controld:

dlm_controld_exec_t

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

dlm_controld_tmpfs_t

- Set files with the dlm_controld_tmpfs_t type, if you want to store dlm controld files on a tmpfs file system.

dlm_controld_var_log_t

- Set files with the dlm_controld_var_log_t type, if you want to treat the data as dlm controld var log data, usually stored under the /var/log directory.

dlm_controld_var_run_t

- Set files with the dlm_controld_var_run_t type, if you want to store the dlm controld files under the /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 database. You will need to use restorecon to apply the labels.

Managed Files

The SELinux process type dlm_controld_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.

cluster_var_lib_t

/var/lib/cluster(/.*)?

dlm_controld_tmpfs_t
dlm_controld_var_log_t

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 policy modules.

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