NAME         top

       default_contexts - The SELinux default contexts configuration
       file

DESCRIPTION         top

       The 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 FORMAT         top

       Each 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.
