Vendor domains must not use Binder 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. Bug: 35870313 Change-Id: I0cd1a80b60bcbde358ce0f7a47b90f4435a45c95 2017-03-23 22:27:32 +01:00			`typeattribute mediaextractor coredomain;`

Split general policy into public and private components. Divide policy into public and private components. This is the first step in splitting the policy creation for platform and non-platform policies. The policy in the public directory will be exported for use in non-platform policy creation. Backwards compatibility with it will be achieved by converting the exported policy into attribute-based policy when included as part of the non-platform policy and a mapping file will be maintained to be included with the platform policy that maps exported attributes of previous versions to the current platform version. Eventually we would like to create a clear interface between the platform and non-platform device components so that the exported policy, and the need for attributes is minimal. For now, almost all types and avrules are left in public. Test: Tested by building policy and running on device.

Properly Treble-ize tmpfs access This is being done in preparation for the migration from ashmem to memfd. In order for tmpfs objects to be usable across the Treble boundary, they need to be declared in public policy whereas, they're currently all declared in private policy as part of the tmpfs_domain() macro. Remove the type declaration from the macro, and remove tmpfs_domain() from the init_daemon_domain() macro to avoid having to declare the *_tmpfs types for all init launched domains. tmpfs is mostly used by apps and the media frameworks. Bug: 122854450 Test: Boot Taimen and blueline. Watch videos, make phone calls, browse internet, send text, install angry birds...play angry birds, keep playing angry birds...

Initial selinux policy support for memfd Move all app tmpfs types to appdomain_tmpfs. These are still protected by mls categories and DAC. TODO clean up other app tmpfs types in a separate change. Treble-ize tmpfs passing between graphics composer HAL and surfaceflinger. Bug: 122854450 Test: boot Blueline with memfd enabled.
