| ### Untrusted apps. |
| ### |
| ### This file defines the rules for untrusted apps. |
| ### 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. |
