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 policy 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.
