|
|
###
|
|
### 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_27 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.
