failsafe_context: The SELinux fail safe context configuration file

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 administrator to access the system.
