6 default_contexts - The SELinux default contexts configuration file
7
9 The default contexts configuration file default_contexts contains
10 entries that allow SELinux-aware login applications such as PAM(8)
11
12 SELinux-aware login applications generally use one or more of the fol‐
13 lowing libselinux functions that read these files from the active pol‐
14 icy path:
15 get_default_context(3)
16 get_ordered_context_list(3)
17 get_ordered_context_list_with_level(3)
18 get_default_context_with_level(3)
19 get_default_context_with_role(3)
20 get_default_context_with_rolelevel(3)
21 query_user_context(3)
22 manual_user_enter_context(3)
23
24 The default context configuration file path for the active policy is
25 returned by selinux_default_contexts_path(3). The default, default con‐
26 texts file is:
27 /etc/selinux/{SELINUXTYPE}/contexts/default_contexts
28
29 Where {SELINUXTYPE} is the entry from the selinux configuration file
30 config (see selinux_config(5)).
31
33 Each line in the default configuration file consists of the following:
34 login_process user_login_process [user_login_process] ...
35
36 Where:
37 login_process
38 This consists of a role:type[:range] entry that repre‐
39 sents the login process context that are defined in the
40 policy.
41 user_login_process
42 This consists of one or more role:type[:range] entries
43 that represent the user login process context defined in
44 the policy.
