failsafe_context(5) SELinux configuration failsafe_context(5) NAME
failsafe_context - The SELinux fail safe context configuration file. DESCRIPTION
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
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 adminis- trator to access the system. EXAMPLE

default_contexts(5) SELinux configuration default_contexts(5) NAME
default_contexts - The SELinux default contexts configuration file DESCRIPTION
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 pol- icy 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
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.
