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 14:27:32 -07:00			`type hal_allocator_default, domain, coredomain;`
Switch Allocator HAL policy to _client/_server This switches Allocator HAL policy to the design which enables us to identify all SELinux domains which host HALs and all domains which are clients of HALs. Allocator HAL is special in the sense that it's assumed to be always binderized. As a result, rules in Camera HAL target hal_allocator_server rather than hal_allocator (which would be the server and any client, if the Allocator HAL runs in passthrough mode). Test: Device boots up, no new denials Test: YouTube video plays back Test: Take photo using Google Camera app, recover a video, record a slow motion video Bug: 34170079 Change-Id: Ifbbca554ec221712361ee6cda94c82f254d84936 2017-03-17 16:51:56 -07:00			`hal_server_domain(hal_allocator_default, hal_allocator)`

Introduce system_file_type system_file_type is a new attribute used to identify files which exist on the /system partition. It's useful for allow rules in init, which are based off of a blacklist of writable files. Additionally, it's useful for constructing neverallow rules to prevent regressions. Additionally, add commented out tests which enforce that all files on the /system partition have the system_file_type attribute. These tests will be uncommented in a future change after all the device-specific policies are cleaned up. Test: Device boots and no obvious problems.

sepolicy for ashmemd all_untrusted_apps apart from untrusted_app_{25, 27} and mediaprovider are now expected to go to ashmemd for /dev/ashmem fds. Give coredomain access to ashmemd, because ashmemd is the default way for coredomain to get a /dev/ashmem fd. Bug: 113362644 Test: device boots, ashmemd running Test: Chrome app works Test: "lsof /system/lib64/libashmemd_client.so" shows libashmemd_client.so being loaded into apps.
