NAME         top

       failsafe_context - The SELinux fail safe context configuration
       file

DESCRIPTION         top

       The failsafe_context file allows SELinux-aware applications such
       as PAM(8) to obtain a known valid login context for an
       administrator if no valid default entries can be found elsewhere.

       selinux_failsafe_context_path(3) will return the active policy
       path to this file. The default failsafe context file is:
              /etc/selinux/{SELINUXTYPE}/contexts/failsafe_context

       Where {SELINUXTYPE} is the entry from the selinux configuration
       file config (see selinux_config(5)).

       The following functions read this file from the active policy
       path if they cannot obtain a default context:
              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)

FILE FORMAT         top

       The file consists of a single line entry as follows:
              role:type[:range]

       Where:
              role type range
                     A role, type and optional range (for MCS/MLS),
                     separated by colons (:) to form a valid login
                     process context for an administrator to access the
                     system.
