.TH "default_contexts" "5" "28-Nov-2011" "Security Enhanced Linux" "SELinux configuration"
.SH "NAME"
default_contexts \- The SELinux default contexts configuration file.
.SH "DESCRIPTION"
The default contexts configuration file \fIdefault_contexts\fR contains entries that allow SELinux-aware login applications such as
.BR PAM "(8) "
.sp
SELinux-aware login applications generally use one or more of the following libselinux functions that read these files from the active policy path:
.RS
.BR get_default_context "(3) "
.br
.BR get_ordered_context_list "(3) "
.br
.BR get_ordered_context_list_with_level "(3) "
.br
.BR get_default_context_with_level "(3) "
.br
.BR get_default_context_with_role "(3) "
.br
.BR get_default_context_with_rolelevel "(3) "
.br
.BR query_user_context "(3) "
.br
.BR manual_user_enter_context "(3) "
.RE
.sp
The default context configuration file path for the active policy is returned by \fBselinux_default_contexts_path\fR(3). The default, default contexts file is:
.RS
.I /etc/selinux/{SELINUXTYPE}/contexts/default_contexts
.RE
.sp
Where \fI{SELINUXTYPE}\fR is the entry from the selinux configuration file \fIconfig\fR (see \fBselinux_config\fR(5)).
.SH "FILE FORMAT"
Each line in the default configuration file consists of the following:
.RS
.I login_process user_login_process [user_login_process] ...
.RE
.sp
Where:
.RS
.I login_process
.RS
This consists of a \fIrole\fB:\fItype\fR[\fB:\fIrange\fR] entry that represents the login process context that are defined in the policy.
.RE
.I user_login_process
.RS
This consists of one or more \fIrole\fB:\fItype\fR[\fB:\fIrange\fR] entries that represent the user login process context defined in the policy.
