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 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.
