Something went wrong on our end

Alex Klyubin authoredOn 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. Bug: 35870313 Change-Id: I0cd1a80b60bcbde358ce0f7a47b90f4435a45c95Alex Klyubin authoredOn PRODUCT_FULL_TREBLE devices, non-vendor domains (except vendor apps) are not permitted to use Binder.
