DO NOT MERGE: Camera: Add initial Treble camera HAL sepolicy - Allow cameraservice to talk to hwbinder, hwservicemanager - Allow hal_camera to talk to the same interfaces as cameraservice Test: Compiles, confirmed that cameraservice can call hwservicemanager Bug: 32991422 Change-Id: Ied0a3f5f7149e29c468a13887510c78d555dcb2a

type hal_camera_default, domain;
Switch Camera HAL policy to _client/_server This switches Camera HAL policy to the design which enables us to conditionally remove unnecessary rules from domains which are clients of Camera HAL. Domains which are clients of Camera HAL, such as cameraserver domain, are granted rules targeting hal_camera only when the Camera HAL runs in passthrough mode (i.e., inside the client's process). When the HAL runs in binderized mode (i.e., in another process/domain, with clients talking to the HAL over HwBinder IPC), rules targeting hal_camera are not granted to client domains. Domains which offer a binderized implementation of Camera HAL, such as hal_camera_default domain, are always granted rules targeting hal_camera.

sepolicy: make exec_types in /vendor a subset of vendor_file_type We install all default hal implementations in /vendor/bin/hw along with a few domains that are defined in vendor policy and installed in /vendor. These files MUST be a subset of the global 'vendor_file_type' which is used to address *all files installed in /vendor* throughout the policy.

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
