On PRODUCT_FULL_TREBLE devices, non-vendor domains (except vendor
apps) are not permitted to use Binder. This commit thus:
* groups non-vendor domains using the new "coredomain" attribute,
* adds neverallow rules restricting Binder use to coredomain and
appdomain only, and
* temporarily exempts the domains which are currently violating this
rule from this restriction. These domains are grouped using the new
"binder_in_vendor_violators" attribute. The attribute is needed
because the types corresponding to violators are not exposed to the
public policy where the neverallow rules are.
Test: mmm system/sepolicy
Test: Device boots, no new denials
Test: In Chrome, navigate to ip6.me, play a YouTube video
Test: YouTube: play a video
Test: Netflix: play a movie
Test: Google Camera: take a photo, take an HDR+ photo, record video with
sound, record slow motion video with sound. Confirm videos play
back fine and with sound.

### 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.
