.SH "NAME"
failsafe_context \- The SELinux fail safe context configuration file
.
.SH "DESCRIPTION"
The
.I failsafe_context
file allows SELinux-aware applications such as
.BR PAM "(8) "
to obtain a known valid login context for an administrator if no valid default entries can be found elsewhere.
.sp
.BR selinux_failsafe_context_path "(3) "
will return the active policy path to this file. The default failsafe context file is:
.RS
.I /etc/selinux/{SELINUXTYPE}/contexts/failsafe_context
.RE
.sp
Where \fI{SELINUXTYPE}\fR is the entry from the selinux configuration file \fIconfig\fR (see \fBselinux_config\fR(5)).
.sp
The following functions read this file from the active policy path if they cannot obtain a default context:
.br
.RS
.BR get_default_context "(3) "
.br
.BR get_ordered_context_list "(3) "
.br
.BR get_ordered_context_list_with_level "(3) "

.RE
