This is a partial cherry pick of commit6231b4d9'Enforce per-app data protections for targetSdk 28+'. Untrusted_app_27 remains unreachable, but it's existence prevents future merge conflicts. Bug: 63897054 Test: build/boot aosp_walleye-userdebug Change-Id: I64b013874fe87b55f47e817a1279e76ecf86b7c0 Merged-In: I64b013874fe87b55f47e817a1279e76ecf86b7c0 (cherry picked from commit6231b4d9fc)

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