7### This file defines the rules for untrusted apps.
8### Apps are labeled based on mac_permissions.xml (maps signer and
9### optionally package name to seinfo value) and seapp_contexts (maps UID
10### and optionally seinfo value to domain for process and type for data
11### directory).  The untrusted_app_27 domain is the default assignment in
12### seapp_contexts for any app with UID between APP_AID (10000)
13### and AID_ISOLATED_START (99000) if the app has no specific seinfo
14### value as determined from mac_permissions.xml.  In current AOSP, this
15### domain is assigned to all non-system apps as well as to any system apps
16### that are not signed by the platform key.  To move
17### a system app into a specific domain, add a signer entry for it to
18### mac_permissions.xml and assign it one of the pre-existing seinfo values
19### or define and use a new seinfo value in both mac_permissions.xml and
20### seapp_contexts.
