15.2. Types
The main permission control method used in SELinux targeted policy to provide advanced process isolation is Type Enforcement. All files and processes are labeled with a type: types define a SELinux domain for processes and a SELinux type for files. SELinux policy rules define how types access each other, whether it be a domain accessing a type, or a domain accessing another domain. Access is only allowed if a specific SELinux policy rule exists that allows it.
The following types are used with Red Hat Gluster Storage. Different types allow you to configure flexible access:
Process types
glusterd_t- The Gluster processes are associated with the
glusterd_tSELinux type.
Types on executables
glusterd_initrc_exec_t- The SELinux-specific script type context for the Gluster init script files.
glusterd_exec_t- The SELinux-specific executable type context for the Gluster executable files.
Port Types
gluster_port_t- This type is defined for
glusterd. By default,glusterduses 204007-24027, and 38465-38469 TCP ports.
File Contexts
glusterd_brick_t- This type is used for files threated as
glusterdbrick data. glusterd_conf_t- This type is associated with the
glusterdconfiguration data, usually stored in the/etc/directory. glusterd_log_t- Files with this type are treated as
glusterdlog data, usually stored under the/var/log/directory. glusterd_tmp_t- This type is used for storing the
glusterdtemporary files in the/tmp/directory. glusterd_var_lib_t- This type allows storing the
glusterdfiles in the/var/lib/directory. glusterd_var_run_t- This type allows storing the
glusterdfiles in the/run/or/var/run/directory.
