Move Graphics Allocator HAL IPC rules to proper location Every client of Graphics Allocator HAL needs permission to (Hw)Binder IPC into the HAL. Test: Device boots, no denials to do with hal_graphics_allocator (also, removing the binder_call(hal_graphics_allocator_client, hal_graphics_allocator_server) leads to denials) Test: GUI works, YouTube works Bug: 34170079 Change-Id: I5c64d966862a125994dab903c2eda5815e336a94

# GPU device access
allow hal_graphics_allocator gpu_device:chr_file rw_file_perms;
Adds GPU sepolicy to support devices with DRM gralloc/rendering ... such as Cuttlefish (Cloud Android virtual device) which has a DRM virtio-gpu based gralloc and (sometimes) DRM virtio-gpu based rendering (when forwarding rendering commands to the host machine with Mesa3D in the guest and virglrenderer on the host). After this change is submitted, changes such as aosp/1997572 can be submitted to removed sepolicy that is currently duplicated across device/google/cuttlefish and device/linaro/dragonboard as well. Adds a sysfs_gpu type (existing replicated sysfs_gpu definitions across several devices are removed in the attached topic). The uses of `sysfs_gpu:file` comes from Mesa using libdrm's `drmGetDevices2()` which calls into `drmParsePciDeviceInfo()` to get vendor id, device id, version etc. Bug: b/161819018 Test: launch_cvd Test: launch_cvd --gpu_mode=gfxstream Change-Id: I4f7d4b0fb90bfeef72f94396ff0c5fe44d53510c Merged-In: I4f7d4b0fb90bfeef72f94396ff0c5fe44d53510c

Grant surfaceflinger and graphics allocator access to the secure heap Transfers access permissions into the system policy which would otherwise be setup on a per-device basis in exactly the same recurring way. For surfacefliner it avoids errors when it (via its dependent graphics libraries) tries to allocate memory from the protected heap, e.g. when operating on a Vulkan device with protected memory support.

# allow to run with real-time scheduling policy
sepolicy: Add rules for non-init namespaces In kernel 4.7, the capability and capability2 classes were split apart from cap_userns and cap2_userns (see kernel commit 8e4ff6f228e4722cac74db716e308d1da33d744f). Since then, Android cannot be run in a container with SELinux in enforcing mode. This change applies the existing capability rules to user namespaces as well as the root namespace so that Android running in a container behaves the same on pre- and post-4.7 kernels. This is essentially: 1. New global_capability_class_set and global_capability2_class_set that match capability+cap_userns and capability2+cap2_userns, respectively. 2. s/self:capability/self:global_capability_class_set/g 3. s/self:capability2/self:global_capability2_class_set/g 4. Add cap_userns and cap2_userns to the existing capability_class_set so that it covers all capabilities. This set was used by several neverallow and dontaudit rules, and I confirmed that the new classes are still appropriate. Test: diff new policy against old and confirm that all new rules add only cap_userns or cap2_userns; Boot ARC++ on a device with the 4.12 kernel.
