2### Untrusted_app_25
3###
4### This file defines the rules for untrusted apps running with
5### targetSdkVersion <= 25.
6###
7### Apps are labeled based on mac_permissions.xml (maps signer and
8### optionally package name to seinfo value) and seapp_contexts (maps UID
9### and optionally seinfo value to domain for process and type for data
10### directory).  The untrusted_app domain is the default assignment in
11### seapp_contexts for any app with UID between APP_AID (10000)
12### and AID_ISOLATED_START (99000) if the app has no specific seinfo
13### value as determined from mac_permissions.xml.  In current AOSP, this
14### domain is assigned to all non-system apps as well as to any system apps
15### that are not signed by the platform key.  To move
16### a system app into a specific domain, add a signer entry for it to
17### mac_permissions.xml and assign it one of the pre-existing seinfo values
18### or define and use a new seinfo value in both mac_permissions.xml and
19### seapp_contexts.
