    Vendor domains must not use Binder · f5446eb1
    Alex Klyubin authored
    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.
