NAMEdefault_contexts − The SELinux default contexts configuration file

---

DESCRIPTIONThe default contexts configuration file default_contexts contains entries that allow SELinux-aware login applications such as PAM(8)" SELinux-aware login applications generally use one or more of the following libselinux functions that read these files from the active policy path: get_default_context(3)"
get_ordered_context_list(3)"
get_ordered_context_list_with_level(3)"
get_default_context_with_level(3)"
get_default_context_with_role(3)"
get_default_context_with_rolelevel(3)"
query_user_context(3)"
manual_user_enter_context(3)" The default context configuration file path for the active policy is returned by selinux_default_contexts_path(3). The default, default contexts file is: /etc/selinux/{SELINUXTYPE}/contexts/default_contexts Where {SELINUXTYPE} is the entry from the selinux configuration file config (see selinux_config(5)).

---

FILE FORMATEach line in the default configuration file consists of the following: login_process user_login_process [user_login_process] ... Where: login_process This consists of a role:type[:range] entry that represents the login process context that are defined in the policy. user_login_process This consists of one or more role:type[:range] entries that represent the user login process context defined in the policy.
