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 recovery_refresh 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.

sepolicy: add version_policy tool and version non-platform policy. In order to support platform changes without simultaneous updates from non-platform components, the platform and non-platform policies must be split. In order to provide a guarantee that policy written for non-platform objects continues to provide the same access, all types exposed to non-platform policy are versioned by converting them and the policy using them into attributes. This change performs that split, the subsequent versioning and also generates a mapping file to glue the different policy components together. Test: Device boots and runs.

In native coverage builds, allow all domains to access /data/misc/trace Bug: http://b/135139675 Coverage files are written to /data/misc/trace (governed by the method_trace_data_file selinux type). Allow all domains to access (create directories, access files) this directory when native coverage is enabled (by setting NATIVE_COVERAGE to true) in an userdebug or eng build. Also relax neverallow constraints to allow access to method_trace_data_file for native coverage builds. Test: Build 32-bit cuttlefish with coverage: m NATIVE_COVERAGE=true COVERAGE_PATHS="*" and verify that there are no selinux denials in kernel log and logcat.
