+     * input AudioPort parameter. This device port must have dynamic profiles

+     * template" because it acts as a template for creating a new instance of a
+     * "connected" device port which gets returned from this method.
+     *
+     * The input AudioPort parameter may contain any additional data obtained by
+     * the system side from other subsystems. The nature of data depends on the
+     * type of the connection. For example, for point-to-multipoint external
+     * device connections, the input parameter may contain the address of the
+     * connected external device. Another example is EDID information for HDMI
+     * connections (ExtraAudioDescriptor), which can be provided by the HDMI-CEC
+     * HAL module.
+     *
+     * It is the responsibility of the HAL module to query audio profiles
+     * supported by the connected device and return them as part of the returned
+     * AudioPort instance. In the case when the HAL is unable to query the
+     * external device, an error must be thrown.
+     *
+     * Thus, the returned audio port instance is the result of combining the
+     * following information:
+     *  - a unique port ID generated by the HAL module;
+     *  - static information from the port template;
+     *  - list of audio profiles supported by the connected device;
+     *  - additional data from the input AudioPort parameter.
+     *
+     * The HAL module must also update the list of audio routes to include the
+     * ID of the instantiated connected device port. Normally, the connected
+     * port allows the same routing as the port template.
+     *
+     * Also see notes on 'ModuleDebug.simulateDeviceConnections'.
+     *
+     * The following protocol is used by HAL module client for handling
+     * connection of an external device:
+     *  1. Obtain the list of device ports and their IDs via 'getAudioPorts'
+     *     method. Select the appropriate port template using
+     *     AudioDeviceDescription ('ext.device' field of AudioPort).
+     *  2. Combine the ID of the port template with any additional data and call
+     *     'connectExternalDevice'. The HAL module returns a new instance of
+     *     AudioPort created using the rules explained above. Both
+     *     'getAudioPort' and 'getAudioPorts' methods will be returning the same
+     *     information for this port until disconnection.
+     *  3. Configure the connected port with one of supported profiles using
+     *     'setAudioPortConfig'.
+     *  4. Query the list of AudioRoutes for the new AudioPort using
+     *     'getAudioRoutesForAudioPort' or 'getAudioRoutes' methods.
+     *
+     * External devices are distinguished by the connection type and device
+     * address. Calling this method multiple times to inform about connection of
+     * the same external device without disconnecting it first is an error.
+     *
+     * The HAL module must perform validation of the input parameter and throw
+     * an error if it is lacking required information, for example, when no
+     * device address is specified for a point-to-multipoint external device
+     * connection.
+     *
+     * Handling of a disconnect is done in a reverse order:
+     *  1. Reset port configuration using the 'resetAudioPortConfig' method.
+     *  2. Release the connected device port by calling the 'disconnectExternalDevice'
+     *     method. This also removes the audio routes associated with this
+     *     device port.
+     *

+/**
+ * Stream descriptor contains fast message queues and buffers used for sending
+ * and receiving audio data. The descriptor complements IStream* interfaces by
+ * providing communication channels that serve as an alternative to Binder
+ * transactions.
+ *
+ * Handling of audio data and commands must be done by the HAL module on a
+ * dedicated thread with high priority, for all modes, including MMap No
+ * IRQ. The HAL module is responsible for creating this thread and setting its
+ * priority. The HAL module is also responsible for serializing access to the
+ * internal components of the stream while serving commands invoked via the
+ * stream's AIDL interface and commands invoked via the command queue of the
+ * descriptor.
+ *
+ * There is a state machine defined for the stream, which executes on the
+ * thread handling the commands from the queue. The states are defined based
+ * on the model of idealized producer and consumer connected via a ring buffer.
+ * For input streams, the "producer" is hardware, the "consumer" is software,
+ * for outputs streams it's the opposite. When the producer is active, but
+ * the buffer is full, the following actions are possible:
+ *  - if the consumer is active, the producer blocks until there is space,
+ *    this behavior is only possible for software producers;
+ *  - if the consumer is passive:
+ *    - the producer can preserve the buffer contents—a s/w producer can
+ *      keep the data on their side, while a h/w producer can only drop captured
+ *      data in this case;
+ *    - or the producer overwrites old data in the buffer.
+ * Similarly, when an active consumer faces an empty buffer, it can:
+ *  - block until there is data (producer must be active), only possible
+ *    for software consumers;
+ *  - walk away with no data; when the consumer is hardware, it must emit
+ *    silence in this case.
+ *
+ * The model is defined below, note the asymmetry regarding the 'IDLE' state
+ * between input and output streams:
+ *
+ *  Producer | Buffer state | Consumer | Applies | State
+ *  active?  |              | active?  | to      |
+ * ==========|==============|==========|=========|==============================
+ *  No       | Empty        | No       | Both    | STANDBY
+ * ----------|--------------|----------|---------|-----------------------------
+ *  Yes      | Filling up   | No       | Input   | IDLE, overwrite behavior
+ * ----------|--------------|----------|---------|-----------------------------
+ *  No       | Empty        | Yes†     | Output  | IDLE, h/w emits silence
+ * ----------|--------------|----------|---------|-----------------------------
+ *  Yes      | Not empty    | Yes      | Both    | ACTIVE, s/w x-runs counted
+ * ----------|--------------|----------|---------|-----------------------------
+ *  Yes      | Filling up   | No       | Input   | PAUSED, drop behavior
+ * ----------|--------------|----------|---------|-----------------------------
+ *  Yes      | Filling up   | No†      | Output  | PAUSED, s/w stops writing once
+ *           |              |          |         | the buffer is filled up;
+ *           |              |          |         | h/w emits silence.
+ * ----------|--------------|----------|---------|-----------------------------
+ *  No       | Not empty    | Yes      | Both    | DRAINING
+ * ----------|--------------|----------|---------|-----------------------------
+ *  No       | Not empty    | No†      | Output  | DRAIN_PAUSED,
+ *           |              |          |         | h/w emits silence.
+ *
+ * † - note that for output, "buffer empty, h/w consuming" has the same outcome
+ *     as "buffer not empty, h/w not consuming", but logically these conditions
+ *     are different.
+ *
+ * State machines of both input and output streams start from the 'STANDBY'
+ * state. Transitions between states happen naturally with changes in the
+ * states of the model elements. For simplicity, we restrict the change to one
+ * element only, for example, in the 'STANDBY' state, either the producer or the
+ * consumer can become active, but not both at the same time. States 'STANDBY',
+ * 'IDLE', 'READY', and '*PAUSED' are "stable"—they require an external event,
+ * whereas a change from the 'DRAINING' state can happen with time as the buffer
+ * gets empty, thus it's a "transient" state.
+ *
+ * The state machine for input streams is defined in the `stream-in-sm.gv` file,
+ * for output streams—in the `stream-out-sm.gv` file. State machines define how
+ * commands (from the enum 'CommandCode') trigger state changes. The full list
+ * of states and commands is defined by constants of the 'State' enum. Note that
+ * the 'CLOSED' state does not have a constant in the interface because the
+ * client can never observe a stream with a functioning command queue in this
+ * state. The 'ERROR' state is a special state which the state machine enters
+ * when an unrecoverable hardware error is detected by the HAL module.
+ *
+ * Non-blocking (asynchronous) modes introduce a new 'TRANSFERRING' state, which
+ * the state machine can enter after replying to the 'burst' command, instead of
+ * staying in the 'ACTIVE' state. In this case the client gets unblocked
+ * earlier, while the actual audio delivery to / from the observer is not
+ * complete yet. Once the HAL module is ready for the next transfer, it notifies
+ * the client via a oneway callback, and the machine switches to 'ACTIVE'
+ * state. The 'TRANSFERRING' state is thus "transient", similar to the
+ * 'DRAINING' state. For output streams, asynchronous transfer can be paused,
+ * and it's another new state: 'TRANSFER_PAUSED'. It differs from 'PAUSED' by
+ * the fact that no new writes are allowed. Please see 'stream-in-async-sm.gv'
+ * and 'stream-out-async-sm.gv' files for details. Below is the table summary
+ * for asynchronous only-states:
+ *
+ *  Producer | Buffer state | Consumer | Applies | State
+ *  active?  |              | active?  | to      |
+ * ==========|==============|==========|=========|==============================
+ *  Yes      | Not empty    | Yes      | Both    | TRANSFERRING, s/w x-runs counted
+ * ----------|--------------|----------|---------|-----------------------------
+ *  Yes      | Not empty    | No       | Output  | TRANSFER_PAUSED,
+ *           |              |          |         | h/w emits silence.

+    <!-- Overview.
+         This example config file was copy from existing one: frameworks/av/media/libeffects/data/
+         audio_effects.xml, with effect library names updated to AIDL libraries we currently have.
+
+         All "library" attributes in "effect" element must must match a "library" element with the
+         same value of the "name" attribute.
+         All "effect" attributes in "preprocess" and "postprocess" element must match an "effect"
+         element with the same value of the "name" attribute.
+
+         AIDL EffectFactory are relying on the "name" attribute in "effect" element to identify the
+         effect type, so it's necessary to have the mapping from name to effect type UUID. Make
+         sure to either use existing effect name as key of
+         ::android::hardware::audio::effect::kUuidNameTypeMap, or add a new {name, typeUUID} map
+         item to the kUuidNameTypeMap.
+
+         Existing audio_effects.xml should working without any change as long as:
+         1. "path" attribute of "library" element matches with the actual effect library name.
+         2. "name" attribute of "effect" and "effectProxy" element correctly added as key of
+            kUuidNameTypeMap, with value matches Identity.type in Descriptor.aidl.
+         3. "uuid" attribute of "effect" element matches Identity.uuid in Descriptor.aidl.
+         4. "uuid" attribute of "effectProxy" element matches Identity.proxy in Descriptor.aidl.

+# Test GRPC Server.
+
+A test GRPC server that implements wakeup_client.proto. This test server acts
+as a reference implementation for a remote wakeup client running on TCU. The
+test server does not communicate with any actual network server. It has the
+following behavior:
+
+* It starts a GRPC server on 'DGRPC_SERVICE_ADDRESS' compile flag which is
+  localhost:50051. The GRPC server provides the service according to
+  hardware/interfaces/automotive/remoteaccess/hal/default/proto/wakeup_client.proto.
+
+  In real implementation, DGRPC_SERVICE_ADDRESS can be specified to any IP
+  address where the TCU can be exposed to Application Processor. The default
+  remote access HAL implementation
+  (hardware/interfaces/automotive/remoteaccess/hal/default/Android.bp) also
+  uses DGRPC_SERVICE_ADDRESS to find this GRPC server, so it must have the
+  same IP address.
+
+* It generates a fake task using FakeTaskGenerator every 'kTaskIntervalInMs' ms.
+
+  In real implementation, it should receive task from the remote server.
+
+* Each fake task has an increasing unique client ID. The task data is always
+  what's defined for 'DATA' variable.
+
+  In real implementation, the client ID and task data should come from the
+  remote server.
+
+* The generated tasks are put into a task queue which is a priority queue sorted
+  by task received time.
+
+  In real implementation, if the server provides a task timestamp, then this
+  queue can be sorted by that task timestamp instead.
+
+* When the Application processor is started, the remote access HAL running on
+  Android will call 'GetRemoteTasks' to establish a long-live connection. This
+  connection is used to deliver all task data from remote wakeup client to
+  remote access HAL, which eventually to car service and applications.
+
+  When the 'GetRemoteTasks' is called, the wakeup client must send all the
+  pending tasks through the 'ServerWriter'. If no task is pending, then it must
+  block and wait for a new task to arrive.
+
+  If one task data fails to be sent through the channel, it likely means
+  the other side (Application processor) is shutting down or has closed the
+  channel. The wakeup client must put the task back to the pending queue and
+  wait for a new 'GetRemoteTasks' request to retry sending the task.
+
+* When a new task arrives, if 'WakeupRequired' is true, then try to wakeup
+  the Application Processor by sending a specific CAN message. It is possible that
+  the waking up is already in progress. This is okay since Vehicle Processor
+  should ignore wakeup message if a wakeup is already in progress.
+
+* When 'WakeupRequired' is updated from false to true, if there are unexpired
+  pending tasks in the task queue, try to wakeup Application Processor.
+
+  This is to handle the situation when a task arrives while the device is
+  shutting down. During the device shutdown, the channel to deliver the remote
+  tasks to Application Processor is shutdown so the new task will be added to the
+  task queue. 'WakeupRequired' will be set to false to prevent the wakeup
+  message preventing the shutdown. After the shutdown is complete,
+  'WakeupRequired' will be set to true and this wakeup client must try to wake
+  up the device again to execute the pending tasks.
+
+* Every pending task has a timeout: 'kTaskTimeoutInMs'. If the pending task
+  is not delivered to remote access HAL before the timeout (through
+  GetRemoteTasks), the task timed out and a warning message is logged.
+
+  In real implementation, this kTaskTimeoutInMs has to be set long enough to
+  allow an Android bootup to happen. 20s is a reasonable value. When a task
+  timed out, the wakeup client should also report to remote task server about
+  the task timeout failure.
+
+## How to build the test wakeup client
+
+* Under android root: `source build/envsetup.sh`
+
+* `lunch sdk_car_x86_64-userdebug`
+
+* `make -j TestWakeupClientServer`
+
+* `make -j ApPowerControlLib`
+
+## How to push the test wakeup client to a TCU which runs Android.
+
+* Make the target device writable:
+
+  `adb root`
+
+  `adb remount` (remount might take a while)
+
+  `adb reboot`
+
+  `adb root`
+
+  `adb remount`
+
+* Under android root: `cd $ANDROID_PRODUCT_OUT`
+
+* `adb push vendor/bin/TestWakeupClientServer /vendor/bin`
+
+* `adb push vendor/lib/ApPowerControlLib.so /vendor/lib`
+
+* `adb shell`
+
+* `su`
+
+* `/vendor/bin/TestWakeupClientServer`
+
+## How to build and test the test wakeup client using one car emulator.
+
+In this test setup we will use one car emulator
+(sdk_car_x86_64-userdebug). We assume both the TCU and the remote access HAL
+runs on the same Android system, and they communicate through local loopback
+interface.
+
+* Under android root, `source build/envsetup.sh`
+
+* `lunch sdk_car_x86_64-userdebug`
+
+* `m -j`
+
+* Run the emulator, the '-read-only' flag is required to run multiple instances:
+
+  `emulator -writable-system -read-only`
+
+* The android lunch target: sdk_car_x86_64-userdebug and
+  cf_x86_64_auto-userdebug already contains the default remote access HAL. For
+  other lunch target, you can add the default remote access HAL by adding
+  'android.hardware.automotive.remoteaccess@V1-default-service' to
+  'PRODUCT_PACKAGES' variable in mk file, see `device/generic/car/common/car.mk`
+  as example.
+
+  To verify whether remote access HAL is running, you can use the following
+  command to check:
+
+  `dumpsys android.hardware.automotive.remoteaccess.IRemoteAccess/default`
+
+* Make the target device writable:
+
+  `adb root`
+
+  `adb remount` (remount might take a while)
+
+  `adb reboot`
+
+  `adb root`
+
+  `adb remount`
+
+* `make -j TestWakeupClientServer`
+
+* `adb push $ANDROID_PRODUCT_OUT/vendor/bin/TestWakeupClientServer /vendor/bin`
+
+* `adb shell`
+
+* `emulator_car_x86_64:/ # su`
+
+* `emulator_car_x86_64:/ # /vendor/bin/TestWakeupClientServer`
+
+* Remote access HAL should start by default when the car emulator starts. Now
+  the test wake up client should also be running and generating fake tasks.
+
+  Start a new session under android root
+
+  `source build/envsetup.sh`
+
+  `lunch sdk_car_x86_64-userdebug`
+
+  `adb shell`
+
+  `emulator_car_x86_64:/ # su`
+
+* Issue the command to start a simple debug callback that will capture all the
+  received tasks at the remote access HAL side:
+
+  `emulator_car_x86_64:/ # dumpsys android.hardware.automotive.remoteaccess.IRemoteAccess/default --start-debug-callback`
+
+* Issue the following debug command to remote access HAL to establish the
+  communication channel between it and the test wakeup client. This command
+  also notifies that wakeup is not required:
+
+  `emulator_car_x86_64:/ # dumpsys android.hardware.automotive.remoteaccess.IRemoteAccess/default --set-ap-state 1 0`
+
+* Wait for a while, issue the following command to show the received fake tasks:
+
+  `emulator_car_x86_64:/ # dumpsys android.hardware.automotive.remoteaccess.IRemoteAccess/default --show-task`
+
+  You should expect to see some received tasks printed out.
+
+* Simulate the Application Processor is shutting down by issuing the following
+  command:
+
+  `emulator_car_x86_64:/ # dumpsys android.hardware.automotive.remoteaccess.IRemoteAccess/default --set-ap-state 0 0`
+
+* Wait for a while, issue the following command to show received tasks again:
+
+  `emulator_car_x86_64:/ # dumpsys android.hardware.automotive.remoteaccess.IRemoteAccess/default --show-task`
+
+  You should expect to see no new tasks received since remote access HAL already
+  closed the communication channel.
+
+* Simulate the Application Processor is already shutdown and wake up is required
+  now:
+
+  `emulator_car_x86_64:/ # dumpsys android.hardware.automotive.remoteaccess.IRemoteAccess/default --set-ap-state 0 1`
+
+  Now you should expect to see the test wakeup client printing out messages
+  that it is trying to wake up application processor.
+
+* Simulate the Application Processor is waken up:
+
+  `emulator_car_x86_64:/ # dumpsys android.hardware.automotive.remoteaccess.IRemoteAccess/default --set-ap-state 1 0`
+
+* A new communication channel should have been established and all pending
+  non-expired tasks should be delivered to the remote access HAL.
+
+  `emulator_car_x86_64:/ # dumpsys android.hardware.automotive.remoteaccess.IRemoteAccess/default --show-task`
+
+* Now you can issue `ctrl c` on the first adb shell to stop the test wakeup
+  client.
+
+* After the test, you can use `ctrl D` to exit the adb shell.
+
+## How to build and test the test wakeup client using two car emulators.
+
+In this test case, we are going to use two car emulators, one as the
+Application Processor, one as the TCU.
+
+* Change the IP address to allow IP communication between different emulator
+  instances. For detail about why we change it this way, see [interconnecting
+  emulator instance](https://developer.android.com/studio/run/emulator-networking#connecting).
+
+  Change 'DGRPC_SERVICE_ADDRESS' in `[android_root]/hardware/interfaces/automotive/remoteaccess/test_grpc_server/impl/Android.bp` to
+  `10.0.2.15:50051`.
+
+  Change `DGRPC_SERVICE_ADDRESS` in '[android_root]/hardware/interfaces/automotive/remoteaccess/hal/defaut/Android.bp' to
+  `10.0.2.2:50051`.
+
+* Under android root: `source build/envsetup.sh`
+
+* `lunch sdk_car_x86_64-userdebug`
+
+*  `m -j`
+
+* Start one car emulator as TCU
+
+  `emulator -writable-system -read-only`
+
+* Start a new shell session. Connect to the emulator's console,
+  see [Start and stop a console session](https://developer.android.com/studio/run/emulator-console#console-session)
+  for detail.
+
+  `telnet localhost 5554`
+
+* `auth auth_token` where auth_token must match the contents of the
+  `~/.emulator_console_auth_token` file.
+
+* `redir add tcp:50051:50051`
+
+* Exit the telnet session using 'ctrl-C'
+
+  Make the target device writable:
+
+  Under android root:
+
+  `source build/envsetup.sh`
+
+  `lunch sdk_car_x86_64-userdebug`
+
+  `adb root`
+
+  `adb remount` (remount might take a while)
+
+  `adb reboot`
+
+  `adb root`
+
+  `adb remount`
+
+* `make -j TestWakeupClientServer`
+
+* `adb push $ANDROID_PRODUCT_OUT/vendor/bin/TestWakeupClientServer /vendor/bin`
+
+* `adb shell`
+
+* `emulator_car_x86_64:/ # su`
+
+* `emulator_car_x86_64:/ # /vendor/bin/TestWakeupClientServer`
+
+* Start a new shell under android root, start another car emulator as the Application Processor:
+
+  `source build/envsetup.sh`
+
+  `lunch sdk_car_x86_64-userdebug`
+
+  `emulator -writable-system -read-only`
+
+* Open a new shell under android root:
+
+  `source build/envsetup.sh`
+
+  `lunch sdk_car_x86_64-userdebug`
+
+* Connect to adb shell for the application processor:
+
+  `adb -s emulator-5556 shell`
+
+  `emulator_car_x86_64:/ # su`
+
+* Follow the test instructions for one car emulator using the 'dumpsys'
+  commands.
+
+* After the test, you can use `ctrl D` to exit the adb shell.

+     * Description for get(...), set(...) and getFromBufferDescriptorInfo(...)
+     *
+     * ------------ Overview -----------------------------------
+     * Gralloc 4 adds support for getting and setting buffer metadata on a buffer.
+     *
+     * To get buffer metadata, the client passes in a buffer handle and a token that
+     * represents the type of buffer metadata they would like to get. IMapper returns
+     * a byte stream that contains the buffer metadata. To set the buffer metadata, the
+     * client passes in a buffer handle and a token that represents the type of buffer
+     * metadata they would like to set and a byte stream that contains the buffer metadata
+     * they are setting.
+     *
+     * Buffer metadata is global for a buffer. When the metadata is set on the buffer
+     * in a process, the updated metadata should be available to all other processes.
+     * Please see "Storing and Propagating Metadata" below for more details.
+     *
+     * The getter and setter functions have been optimized for easy vendor extension.
+     * They do not require a formal extension to add support for getting and setting
+     * vendor defined buffer metadata. See "Buffer Metadata Token" and
+     * "Buffer Metadata Stream" below for more details.
+     *
+     * ------------ Storing and Propagating Metadata -----------
+     * Buffer metadata must be global. Any changes to the metadata must be propagated
+     * to all other processes immediately. Vendors may chose how they would like support
+     * this functionality.
+     *
+     * We recommend supporting this functionality by allocating an extra page of shared
+     * memory and storing it in the buffer's native_handle_t. The buffer metadata can
+     * be stored in the extra page of shared memory. Set operations are automatically
+     * propagated to all other processes.
+     *
+     * ------------ Buffer Metadata Synchronization ------------
+     * There are no explicit buffer metadata synchronization primitives. Many devices
+     * before gralloc 4 already support getting and setting of global buffer metadata
+     * with no explicit synchronization primitives. Adding synchronization primitives
+     * would just add unnecessary complexity.
+     *
+     * The general rule is if a process has permission to write to a buffer, they
+     * have permission to write to the buffer's writable metadata. If a process has permission
+     * to read from a buffer, they have permission to read the buffer's metadata.
+     *
+     * There is one exception to this rule. Fences CANNOT be used to protect a buffer's
+     * metadata. A process should finish writing to a buffer's metadata before
+     * sending the buffer to another process that will read or write to the buffer.
+     * This exception is needed because sometimes userspace needs to read the
+     * buffer's metadata before the buffer's contents are ready.
+     *
+     * As a simple example: an app renders to a buffer and then displays the buffer.
+     * In this example when the app renders to the buffer, both the buffer and its
+     * metadata need to be updated. The app's process queues up its work on the GPU
+     * and gets back an acquire fence. The app's process must update the buffer's
+     * metadata before enqueuing the buffer to SurfaceFlinger. The app process CANNOT
+     * update the buffer's metadata after enqueuing the buffer. When HardwareComposer
+     * receives the buffer, it is immediately safe to read the buffer's metadata
+     * and use it to program the display driver. To read the buffer's contents,
+     * display driver must still wait on the acquire fence.
+     *
+     * ------------ Buffer Metadata Token ----------------------
+     * In order to allow arbitrary vendor defined metadata, the token used to access
+     * metadata is defined defined as a struct that has a string representing
+     * the enum type and an int that represents the enum value. The string protects
+     * different enum values from colliding.
+     *
+     * The token struct (MetadataType) is defined as a C struct since it
+     * is passed into a C function. The standard buffer metadata types are NOT
+     * defined as a C enum but instead as an AIDL enum to allow for broader usage across
+     * other HALs and libraries. By putting the enum in the
+     * stable AIDL (hardware/interfaces/graphics/common/aidl/android/hardware/
+     * graphics/common/StandardMetadataType.aidl), vendors will be able to optionally
+     * choose to support future standard buffer metadata types without upgrading
+     * IMapper versions. For more information see the description of "struct MetadataType".
+     *
+     * ------------ Buffer Metadata Stream ---------------------
+     * The buffer metadata is get and set as a void* buffer. By getting
+     * and setting buffer metadata as a generic buffer, vendors can use the standard
+     * getters and setter functions defined here. Vendors do NOT need to add their own
+     * getters and setter functions for each new type of buffer metadata.
+     *
+     * Converting buffer metadata into a byte stream can be non-trivial. For the standard
+     * buffer metadata types defined in StandardMetadataType.aidl, there are also
+     * support functions that will encode the buffer metadata into a byte stream
+     * and decode the buffer metadata from a byte stream. We STRONGLY recommend using
+     * these support functions. The framework will use them when getting and setting
+     * metadata. The support functions are defined in
+     * frameworks/native/libs/gralloc/types/include/gralloctypes/Gralloc4.h.

+// type is used to build AIDL files in a way that they can be used across

-# Remote Provisioning HAL
-
-## Objective
-
-Design a HAL to support over-the-air provisioning of certificates for asymmetric
-keys. The HAL must interact effectively with Keystore (and other daemons) and
-protect device privacy and security.
-
-Note that this API is designed for KeyMint, but with the intention that it
-should be usable for other HALs that require certificate provisioning.
-Throughout this document we'll refer to the Keystore and KeyMint (formerly
-called Keymaster) components, but only for concreteness and convenience; those
-labels could be replaced with the names of any system and secure area
-components, respectively, that need certificates provisioned.
-
-## Key design decisions
-
-### General approach
-
-To more securely and reliably get keys and certificates to Android devices, we
-need to create a system where no party outside of the device's secure components
-is responsible for managing private keys. The strategy we've chosen is to
-deliver certificates over the air, using an asymmetric key pair created
-on-device in the factory as a root of trust to create an authenticated, secure
-channel. In this document we refer to this device-unique asymmetric key pair as
-Device Key (DK), its public half DK\_pub, its private half DK\_priv and a Device
-Key Certificate containing DK\_pub is denoted DKC.
-
-In order for the provisioning service to use DK (or a key authenticated by DK),
-it must know whether a given DK\_pub is known and trusted. To prove trust, we
-ask device OEMs to use one of two mechanisms:
-
-1.  (Preferred, recommended) The device OEM extracts DK\_pub from each device it
-    manufactures and uploads the public keys to a backend server.
-
-1.  The device OEM signs the DK\_pub to produce DKC and stores it on the device.
-    This has the advantage that they don't need to upload a DK\_pub for every
-    device immediately, but the disadvantage that they have to manage their
-    private signing keys, which means they have to have HSMs, configure and
-    secure them correctly, etc. Some backend providers may also require that the
-    OEM passes a factory security audit, and additionally promises to upload the
-    keys eventually as well.
-
-Note that in the full elaboration of this plan, DK\_pub is not the key used to
-establish a secure channel. Instead, DK\_pub is just the first public key in a
-chain of public keys which ends with the KeyMint public key, KM\_pub. All keys
-in the chain are device-unique and are joined in a certificate chain called the
-_Boot Certificate Chain_ (BCC), because in phases 2 and 3 of the remote
-provisioning project it is a chain of certificates corresponding to boot phases.
-We speak of the BCC even for phase 1, though in phase 1 it contains only a
-single self-signed DKC. This is described in more depth in the Phases section
-below.
-
-The BCC is authenticated by DK\_pub. To authenticate DK\_pub, we may have
-additional DKCs, from the SoC vendor, the device OEM, or both. Those are not
-part of the BCC but included as optional fields in the certificate request
-structure.
-
-The format of the the DK and BCC is specified within [Open Profile for DICE]
-(https://pigweed.googlesource.com/open-dice/+/HEAD/docs/specification.md).  To
-map phrases within this document to their equivalent terminology in the DICE
-specification, read the terms as follows: the DK corresponds to the UDS-derived
-key pair, DKC corresponds to the UDS certificate, and the BCC entries between
-DK\_pub and KM\_pub correspond to a chain of CDI certificates.
-
-Note: In addition to allowing 32 byte hash values for fields in the BCC payload,
-this spec additionally constrains some of the choices allowed in open-DICE.
-Specifically, these include which entries are required and which are optional in
-the BCC payload, and which algorithms are acceptable for use.
-
-### Phases
-
-RKP will be deployed in three phases, in terms of managing the root of trust
-binding between the device and the backend. To briefly describe them:
-
-* Phase 1: In phase 1 there is only one entry in the BCC; DK_pub and KM_pub are
-  the same key and the certificate is self-signed.
-* Phase 2: This is identical to phase 1, except it leverages the hardware root
-  of trust process described by DICE. Instead of trust being rooted in the TEE,
-  it is now rooted in the ROM by key material blown into fuses which are only
-  accessible to the ROM code.
-* Phase 3: This is identical to Phase 2, except the SoC vendor also does the
-  public key extraction or certification in their facilities, along with the OEM
-  doing it in the factory. This tightens up the "supply chain" and aims to make
-  key upload management more secure.
-
-### Privacy considerations
-
-Because DK and the DKCs are unique, immutable, unspoofable hardware-bound
-identifiers for the device, we must limit access to them to the absolute minimum
-possible. We do this in two ways:
-
-1.  We require KeyMint (which knows the BCC and either knows or at least has the
-ability to use KM\_priv) to refuse to ever divulge the BCC or additional
-signatures in plaintext. Instead, KeyMint requires the caller to provide an
-_Endpoint Encryption Key_ (EEK), with which it will encrypt the data before
-returning it. When provisioning production keys, the EEK must be signed by an
-approved authority whose public key is embedded in KeyMint. When certifying test
-keys, KeyMint will accept any EEK without checking the signature, but will
-encrypt and return a test BCC, rather than the real one.  The result is that
-only an entity in possession of an Trusted EEK (TEEK) private key can discover
-the plaintext of the production BCC.
-1.  Having thus limited access to the public keys to the trusted party only, we
-need to prevent the entity from abusing this unique device identifier.  The
-approach and mechanisms for doing that are beyond the scope of this document
-(they must be addressed in the server design), but generally involve taking care
-to ensure that we do not create any links between user IDs, IP addresses or
-issued certificates and the device pubkey.
-
-Although the details of the mechanisms for preventing the entity from abusing
-the BCC are, as stated, beyond the scope of this document, there is a subtle
-design decision here made specifically to enable abuse prevention. Specifically
-the `CertificateRequest` message sent to the server is (in
-[CDDL](https://tools.ietf.org/html/rfc8610)):
-
-```
-cddl
-CertificateRequest = [
-    DeviceInfo,
-    challenge : bstr,
-    ProtectedData,
-    MacedKeysToSign
-]
-```
-
-The public keys to be attested by the server are in `MacedKeysToSign`, which is
-a COSE\_Mac0 structure, MACed with a key that is found in `ProtectedData`. The
-MAC key is signed by DK\_pub.
-
-This structure allows the backend component that has access to EEK\_priv to
-decrypt `ProtectedData`, validate that the request is from an authorized device,
-check that the request is fresh and verify and extract the MAC key. That backend
-component never sees any data related to the keys to be signed, but can provide
-the MAC key to another backend component that can verify `MacedKeysToSign` and
-proceed to generate the certificates.
-
-In this way, we can partition the provisioning server into one component that
-knows the device identity, as represented by DK\_pub, but never sees the keys to
-be certified or certificates generated, and another component that sees the keys
-to be certified and certificates generated but does not know the device
-identity.
-
-### Key and cryptographic message formatting
-
-For simplicity of generation and parsing, compactness of wire representation,
-and flexibility and standardization, we've settled on using the CBOR Object
-Signing and Encryption (COSE) standard, defined in [RFC
-8152](https://tools.ietf.org/html/rfc8152). COSE provides compact and reasonably
-simple, yet easily-extensible, wire formats for:
-
-*   Keys,
-*   MACed messages,
-*   Signed messages, and
-*   Encrypted messages
-
-COSE enables easy layering of these message formats, such as using a COSE\_Sign
-structure to contain a COSE\_Key with a public key in it. We call this a
-"certificate".
-
-Due to the complexity of the standard, we'll spell out the COSE structures
-completely in this document and in the HAL and other documentation, so that
-although implementors will need to understand CBOR and the CBOR Data Definition
-Language ([CDDL, defined in RFC 8610](https://tools.ietf.org/html/rfc8610)),
-they shouldn't need to understand COSE.
-
-Note, however, that the certificate chains returned from the provisioning server
-are standard X.509 certificates.
-
-### Algorithm choices
-
-This document uses:
-
-*   ECDSA P-256 for attestation signing keys;
-*   Remote provisioning protocol signing keys:
-  *  Ed25519 / P-256
-*   ECDH keys:
-  *  X25519 / P-256
-*   AES-GCM for all encryption;
-*   SHA-256 for all message digesting;
-*   HMAC-SHA-256 for all MACing; and
-*   HKDF-SHA-256 for all key derivation.
-
-We believe that Curve25519 offers the best tradeoff in terms of security,
-efficiency and global trustworthiness, and that it is now sufficiently
-widely-used and widely-implemented to make it a practical choice.
-
-However, since Secure Elements (SE) do not currently offer support for curve
-25519, we are allowing implementations to instead make use of EC P-256 for
-signing and ECDH. To put it simply, the device unique key pair will be a P-256
-key pair for ECDSA instead of Ed25519, and the ProtectedData COSE\_Encrypt
-message will have its payload encrypted with P-256 ECDH key exchange instead of
-X25519.
-
-The CDDL in the rest of the document will use the '/' operator to show areas
-where either curve 25519 or P-256 may be used. Since there is no easy way to
-bind choices across different CDDL groups, it is important that the implementor
-stays consistent in which type is chosen. E.g. taking ES256 as the choice for
-algorithm implies the implementor should also choose the P256 public key group
-further down in the COSE structure.
-
-### Testability
-
-It's critical that the remote provisioning implementation be testable, to
-minimize the probability that broken devices are sold to end users. To support
-testing, the remote provisioning HAL methods take a `testMode` argument. Keys
-created in test mode are tagged to indicate this. The provisioning server will
-check for the test mode tag and issue test certificates that do not chain back
-to a trusted public key. In test mode, any EEK will be accepted, enabling
-testing tools to use EEKs for which they have the private key so they can
-validate the content of certificate requests. The BCC included in the
-`CertificateRequest` must contain freshly-generated keys, not the real BCC keys.
-
-Keystore (or similar) will need to be able to handle both testMode keys and
-production keys and keep them distinct, generating test certificate requests
-when asked with a test EEK and production certificate requests when asked with a
-production EEK. Likewise, the interface used to instruct Keystore to create keys
-will need to be able to specify whether test or production keys are desired.
-
-## Design
-
-### Certificate provisioning flow
-
-TODO(jbires): Replace this with a `.png` containing a sequence diagram.  The
-provisioning flow looks something like this:
-
-Provisioner -> Keystore: Prepare N keys
-Keystore -> KeyMint: generateKeyPair
-KeyMint -> KeyMint: Generate  key pair
-KeyMint --> Keystore: key\_blob,pubkey
-Keystore -> Keystore: Store key\_blob,pubkey
-Provisioner -> Server: Get TEEK
-Server --> Provisioner: TEEK
-Provisioner -> Keystore: genCertReq(N, TEEK)
-Keystore -> KeyMint: genCertReq(pubkeys, TEEK)
-KeyMint -> KeyMint: Sign pubkeys & encrypt BCC
-KeyMint --> Keystore: signature, encrypted BCC
-Keystore -> Keystore: Construct cert\_request
-Keystore --> Provisioner: cert\_request
-Provisioner --> Server: cert\_request
-Server -> Server: Validate cert\_request
-Server -> Server: Generate certificates
-Server --> Provisioner: certificates
-Provisioner -> Keystore: certificates
-Keystore -> Keystore: Store certificates
-
-The actors in the above diagram are:
-
-*   **Server** is the backend certificate provisioning server. It has access to
-    the uploaded device public keys and is responsible for providing encryption
-    keys, decrypting and validating requests, and generating certificates in
-    response to requests.
-*   **Provisioner** is an application that is responsible for communicating with
-    the server and all of the system components that require key certificates
-    from the server. It also implements the policy that defines how many key
-    pairs each client should keep in their pool.
-*   **Keystore** is the [Android keystore
-    daemon](https://developer.android.com/training/articles/keystore) (or, more
-    generally, whatever system component manages communications with a
-    particular secure aread component).
-*   **KeyMint** is the secure area component that manages cryptographic keys and
-    performs attestations (or perhaps some other secure area component).
-
-### `BCC`
-
-The _Boot Certificate Chain_ (BCC) is the chain of certificates that contains
-DK\_pub as well as other often device-unique certificates. The BCC is
-represented as a COSE\_Key containing DK\_pub followed by an array of
-COSE\_Sign1 "certificates" containing public keys and optional additional
-information, ordered from root to leaf, with each certificate signing the next.
-The first certificate in the array is signed by DK\_pub, the last certificate
-has the KeyMint (or whatever) signing key's public key, KM\_pub. In phase 1
-there is only one entry; DK\_pub and KM\_pub are the same key and the
-certificate is self-signed.
-
-Each COSE\_Sign1 certificate is a CBOR Web Token (CWT) as described in [RFC
-8392](https://tools.ietf.org/html/rfc8392) with additional fields as described
-in the Open Profile for DICE. Of these additional fields, only the
-_subjectPublicKey_ and _keyUsage_ fields are expected to be present for the
-KM\_pub entry (that is, the last entry) in a BCC, but all fields required by the
-Open Profile for DICE are expected for other entries (each of which corresponds
-to a particular firmware component or boot stage). The CWT fields _iss_ and
-_sub_ identify the issuer and subject of the certificate and are consistent
-along the BCC entries; the issuer of a given entry matches the subject of the
-previous entry.
-
-The BCC is designed to be constructed using the Open Profile for DICE. In this
-case the DK key pair is derived from the UDS as described by that profile and
-all BCC entries before the leaf are CBOR CDI certificates chained from DK\_pub.
-The KM key pair is not part of the derived DICE chain. It is generated (not
-derived) by the KeyMint module, certified by the last key in the DICE chain, and
-added as the leaf BCC entry. The key usage field in this leaf certificate must
-indicate the key is not used to sign certificates. If a UDS certificate is
-available on the device it should appear in the certificate request as the leaf
-of a DKCertChain in AdditionalDKSignatures (see
-[CertificateRequest](#certificaterequest)).
-
-The Open Profile for DICE allows for an arbitrary configuration descriptor. For
-BCC entries, this configuration descriptor is a CBOR map with the following
-optional fields. If no fields are relevant, an empty map should be encoded.
-Additional implementation-specific fields may be added using key values not in
-the range \[-70000, -70999\] (these are reserved for future additions here).

-
-Please see
-[ProtectedData.aidl](https://cs.android.com/android/platform/superproject/+/master:hardware/interfaces/security/keymint/aidl/android/hardware/security/keymint/ProtectedData.aidl)
-for a full CDDL definition of the BCC.
-
-### `CertificateRequest`
-
-The full CBOR message that will be sent to the server to request certificates
-is:
-
-```cddl
-CertificateRequest = [
-    DeviceInfo,
-    challenge : bstr,       // Provided by the server
-    ProtectedData,          // See ProtectedData.aidl
-    MacedKeysToSign         // See IRemotelyProvisionedComponent.aidl
-]
-
-DeviceInfo = [
-    VerifiedDeviceInfo,     // See DeviceInfo.aidl
-    UnverifiedDeviceInfo
-]
-
-// Unverified info is anything provided by the HLOS. Subject to change out of
-// step with the HAL.
-UnverifiedDeviceInfo = {
-    ? "fingerprint" : tstr,
-}
-
-```
-
-It will be the responsibility of Keystore and the Provisioner to construct the
-`CertificateRequest`. The HAL provides a method to generate the elements that
-need to be constructed on the secure side, which are the tag field of
-`MacedKeysToSign`, `VerifiedDeviceInfo`, and the ciphertext field of
-`ProtectedData`.
-
-### HAL
-
-The remote provisioning HAL provides a simple interface that can be implemented
-by multiple secure components that require remote provisioning. It would be
-slightly simpler to extend the KeyMint API, but that approach would only serve
-the needs of KeyMint, this is more general.
-
-NOTE the data structures defined in this HAL may look a little bloated and
-complex. This is because the COSE data structures are fully spelled-out; we
-could make it much more compact by not re-specifying the standardized elements
-and instead just referencing the standard, but it seems better to fully specify
-them. If the apparent complexity seems daunting, consider what the same would
-look like if traditional ASN.1 DER-based structures from X.509 and related
-standards were used and also fully elaborated.
-
-Please see the related HAL documentation directly in the source code at the
-following links:

-/**
- * An IRemotelyProvisionedComponent is a secure-side component for which certificates can be
- * remotely provisioned. It provides an interface for generating asymmetric key pairs and then
- * creating a CertificateRequest that contains the generated public keys, plus other information to
- * authenticate the request origin. The CertificateRequest can be sent to a server, which can
- * validate the request and create certificates.
- *
- * This interface does not provide any way to use the generated and certified key pairs. It's
- * intended to be implemented by a HAL service that does other things with keys (e.g. Keymint).
- *
- * The root of trust for secure provisioning is something called the "Boot Certificate Chain", or
- * BCC. The BCC is a chain of public key certificates, represented as COSE_Sign1 objects containing
- * COSE_Key representations of the public keys. The "root" of the BCC is
- * a device-unique public key, denoted DK_pub. All public keys in the BCC are device-unique. The
- * public key from each certificate in the chain is used to sign the next certificate in the
- * chain. The final, "leaf" certificate contains a public key, denoted KM_pub, whose corresponding
- * private key, denoted KM_priv, is available for use by the IRemotelyProvisionedComponent.
- *
- * BCC Design
- * ==========
- *
- * The BCC is designed to mirror the boot stages of a device, and to prove the content and integrity
- * of each firmware image. In a proper BCC, each boot stage hashes its own private key with the code
- * and any relevant configuration parameters of the next stage to produce a key pair for the next
- * stage. Each stage also uses its own private key to sign the public key of the next stage,
- * including in the certificate the hash of the next firmware stage, then loads the next stage,
- * passing the private key and certificate to it in a manner that does not leak the private key to
- * later boot stages. The BCC root key pair is generated by immutable code (e.g. ROM), from a
- * device-unique secret. After the device-unique secret is used, it must be made unavailable to any
- * later boot stage.
- *
- * In this way, booting the device incrementally builds a certificate chain that (a) identifies and
- * validates the integrity of every stage and (b) contains a set of public keys that correspond to
- * private keys, one known to each stage. Any stage can compute the secrets of all later stages
- * (given the necessary input), but no stage can compute the secret of any preceding stage. Updating
- * the firmware or configuration of any stage changes the key pair of that stage, and of all
- * subsequent stages, and no attacker who compromised the previous version of the updated firmware
- * can know or predict the post-update key pairs. It is recommended and expected that the BCC is
- * constructed using the Open Profile for DICE.
- *
- * When the provisioning server receives a message signed by KM_priv and containing a BCC that
- * chains from DK_pub to KM_pub, it can be certain that (barring vulnerabilities in some boot
- * stage), the CertificateRequest came from the device associated with DK_pub, running the specific
- * software identified by the certificates in the BCC. If the server has some mechanism for knowing
- * which the DK_pub values of "valid" devices, it can determine whether signing certificates is
- * appropriate.
- *
- * Degenerate BCCs
- * ===============
- *
- * While a proper BCC, as described above, reflects the complete boot sequence from boot ROM to the
- * secure area image of the IRemotelyProvisionedComponent, it's also possible to use a "degenerate"
- * BCC which consists only of a single, self-signed certificate containing the public key of a
- * hardware-bound key pair. This is an appopriate solution for devices which haven't implemented
- * everything necessary to produce a proper BCC, but can derive a unique key pair in the secure
- * area.  In this degenerate case, DK_pub is the same as KM_pub.
- *
- * BCC Privacy
- * ===========
- *
- * Because the BCC constitutes an unspoofable, device-unique identifier, special care is taken to
- * prevent its availability to entities who may wish to track devices. Two precautions are taken:
- *
- * 1.  The BCC is never exported from the IRemotelyProvisionedComponent except in encrypted
- *     form. The portion of the CertificateRequest that contains the BCC is encrypted using an
- *     Endpoint Encryption Key (EEK).  The EEK is provided in the form of a certificate chain whose
- *     root must be pre-provisioned into the secure area (hardcoding the roots into the secure area
- *     firmware image is a recommended approach). Multiple roots may be provisioned. If the provided
- *     EEK does not chain back to this already-known root, the IRemotelyProvisionedComponent must
- *     reject it.
- *
- * 2.  Precaution 1 above ensures that only an entity with a valid EEK private key can decrypt the
- *     BCC. To make it feasible to build a provisioning server which cannot use the BCC to track
- *     devices, the CertificateRequest is structured so that the server can be partitioned into two
- *     components.  The "decrypter" decrypts the BCC, verifies DK_pub and the device's right to
- *     receive provisioned certificates, but does not see the public keys to be signed or the
- *     resulting certificates.  The "certifier" gets informed of the results of the decrypter's
- *     validation and sees the public keys to be signed and resulting certificates, but does not see
- *     the BCC.
- *
- * Test Mode
- * =========
- *
- * The IRemotelyProvisionedComponent supports a test mode, allowing the generation of test key pairs
- * and test CertificateRequests. Test keys/requests are annotated as such, and the BCC used for test
- * CertificateRequests must contain freshly-generated keys, not the real BCC key pairs.

+# Remote Provisioning Changelog
+
+This document provides an exact description of which changes have occurred in the
+`IRemotelyProvisionedComponent` HAL interface in each Android release.
+
+## Releases
+* **Android S (12):** IRemotelyProvisionedComponent v1
+* **Android T (13):** IRemotelyProvisionedComponent v2
+* **Android U (14):** IRemotelyProvisionedComponent v3
+
+## IRemotelyProvisionedComponent 1 -> 2
+* DeviceInfo
+  * Most entries are no longer optional.
+  * `att_id_state` is now `fused`. `fused` is used to indicate if SecureBoot is enabled.
+  * `version` is now `2`.
+  * `board` has been removed.
+  * `device` has been added.
+* RpcHardwareInfo
+  * `uniqueId` String added as a field in order to differentiate IRPC instances on device.
+
+## IRemotelyProvisionedComponent 2 -> 3
+* The RKP HAL now builds separately from KeyMint.
+  * The HAL remains under the `android.hardware.security.keymint` package for
+    compatibility with previous releases. ABI compatibility requires this.
+  * Dependencies on the RKP HAL must add a dependency on
+    `"android.hardware.security.rkp"` generated code (instead of
+    `"android.hardward.security.keymint"`).
+* ProtectedData has been removed.
+* DeviceInfo
+  * `version` has moved to a top-level field within the CSR generated by the HAL.
+* IRemotelyProvisionedComponent
+  * The need for an EEK has been removed. There is no longer an encrypted portion of the CSR.
+  * Keys for new CSR format must be generated with test mode set to false, effectively removing test
+    mode in the new CSR flow. Old behavior is kept unchanged for backwards compatibility.
+  * The schema for the CSR itself has been significantly simplified, please see
+    IRemotelyProvisionedComponent.aidl for more details. Notably,
+    * the chain of signing, MACing, and encryption operations has been replaced with a single
+      COSE_Sign1 object.
+    * CertificateType has been added to identify the type of certificate being requested.
+    * The structure has been composed to enable a clear split between what is required to validate a
+      payload and the implementation-defined payload itself. This is done by creating a typed
+      `AuthenticatedRequest<T>` object representing the top level data required to authenticate
+      the data provided in the payload, `T`.
+* RpcHardwareInfo
+  * `supportedNumKeysInCsr` added to report the maximum number of keys supported in a CSR.
+  * `supportedEekCurve` is no longer used, due to the removal of the EEK from the scheme.

+# Remote Provisioning HAL
+
+## Objective
+
+Design a HAL to support over-the-air provisioning of certificates for asymmetric
+keys. The HAL must interact effectively with Keystore (and other daemons) and
+protect device privacy and security.
+
+Note that this API was originally designed for KeyMint, with the intention that
+it should be usable for other HALs that require certificate provisioning.
+Throughout this document we'll refer to the Keystore and KeyMint (formerly
+called Keymaster) components, but only for concreteness and convenience; those
+labels could be replaced with the names of any system and secure area
+components, respectively, that need certificates provisioned.
+
+## Key design decisions
+
+### General approach
+
+To more securely and reliably get keys and certificates to Android devices, we
+need to create a system where no party outside of the device's secure components
+is responsible for managing private keys. The strategy we've chosen is to
+deliver certificates over the air, using an asymmetric key pair created
+on-device in the factory as a root of trust to create an authenticated, secure
+channel. In this document we refer to this device-unique asymmetric key pair as
+Device Key (DK), its public half DK\_pub, its private half DK\_priv and a Device
+Key Certificate containing DK\_pub is denoted DKC.
+
+In order for the provisioning service to use DK (or a key authenticated by DK),
+it must know whether a given DK\_pub is known and trusted. To prove trust, we
+ask device OEMs to use one of two mechanisms:
+
+1.  (Preferred, recommended) The device OEM extracts DK\_pub from each device it
+    manufactures and uploads the public keys to a backend server.
+
+1.  The device OEM signs the DK\_pub to produce DKC and stores it on the device.
+    This has the advantage that they don't need to upload a DK\_pub for every
+    device immediately, but the disadvantage that they have to manage their
+    private signing keys, which means they have to have HSMs, configure and
+    secure them correctly, etc. Some backend providers may also require that the
+    OEM passes a factory security audit, and additionally promises to upload the
+    keys eventually as well.
+
+Note that in the full elaboration of this plan, DK\_pub is not the key used to
+establish a secure channel. Instead, DK\_pub is just the first public key in a
+chain of public keys which ends with the KeyMint public key, KM\_pub. All keys
+in the chain are device-unique and are joined in a certificate chain called the
+_Boot Certificate Chain_ (BCC), because in phases 2 and 3 of the remote
+provisioning project it is a chain of certificates corresponding to boot phases.
+We speak of the BCC even for phase 1, though in phase 1 it contains only a
+single self-signed DKC. This is described in more depth in the Phases section
+below.
+
+The BCC is authenticated by DK\_pub. To authenticate DK\_pub, we may have
+additional DKCs, from the SoC vendor, the device OEM, or both. Those are not
+part of the BCC but included as optional fields in the certificate request
+structure.
+
+The format of the the DK and BCC is specified within [Open Profile for DICE]
+(https://pigweed.googlesource.com/open-dice/+/HEAD/docs/specification.md).  To
+map phrases within this document to their equivalent terminology in the DICE
+specification, read the terms as follows: the DK corresponds to the UDS-derived
+key pair, DKC corresponds to the UDS certificate, and the BCC entries between
+DK\_pub and KM\_pub correspond to a chain of CDI certificates.
+
+Note: In addition to allowing 32 byte hash values for fields in the BCC payload,
+this spec additionally constrains some of the choices allowed in open-DICE.
+Specifically, these include which entries are required and which are optional in
+the BCC payload, and which algorithms are acceptable for use.
+
+### Phases
+
+RKP will be deployed in three phases, in terms of managing the root of trust
+binding between the device and the backend. To briefly describe them:
+
+* Phase 1: In phase 1 there is only one entry in the BCC; DK_pub and KM_pub are
+  the same key and the certificate is self-signed.
+* Phase 2: This is identical to phase 1, except it leverages the hardware root
+  of trust process described by DICE. Instead of trust being rooted in the TEE,
+  it is now rooted in the ROM by key material blown into fuses which are only
+  accessible to the ROM code.
+* Phase 3: This is identical to Phase 2, except the SoC vendor also does the
+  public key extraction or certification in their facilities, along with the OEM
+  doing it in the factory. This tightens up the "supply chain" and aims to make
+  key upload management more secure.
+
+### Privacy considerations
+
+Because DK and the DKCs are unique, immutable, unspoofable hardware-bound
+identifiers for the device, we must limit access to them to the absolute minimum
+possible. We do this in two ways:
+
+1.  We require KeyMint (which knows the BCC and either knows or at least has the
+ability to use KM\_priv) to refuse to ever divulge the BCC or additional
+signatures in plaintext. Instead, KeyMint requires the caller to provide an
+_Endpoint Encryption Key_ (EEK), with which it will encrypt the data before
+returning it. When provisioning production keys, the EEK must be signed by an
+approved authority whose public key is embedded in KeyMint. When certifying test
+keys, KeyMint will accept any EEK without checking the signature, but will
+encrypt and return a test BCC, rather than the real one.  The result is that
+only an entity in possession of an Trusted EEK (TEEK) private key can discover
+the plaintext of the production BCC.
+1.  Having thus limited access to the public keys to the trusted party only, we
+need to prevent the entity from abusing this unique device identifier.  The
+approach and mechanisms for doing that are beyond the scope of this document
+(they must be addressed in the server design), but generally involve taking care
+to ensure that we do not create any links between user IDs, IP addresses or
+issued certificates and the device pubkey.
+
+Although the details of the mechanisms for preventing the entity from abusing
+the BCC are, as stated, beyond the scope of this document, there is a subtle
+design decision here made specifically to enable abuse prevention. Specifically
+the `CertificateRequest` message sent to the server is (in
+[CDDL](https://tools.ietf.org/html/rfc8610)):
+
+```
+cddl
+CertificateRequest = [
+    DeviceInfo,
+    challenge : bstr,
+    ProtectedData,
+    MacedKeysToSign
+]
+```
+
+The public keys to be attested by the server are in `MacedKeysToSign`, which is
+a COSE\_Mac0 structure, MACed with a key that is found in `ProtectedData`. The
+MAC key is signed by DK\_pub.
+
+This structure allows the backend component that has access to EEK\_priv to
+decrypt `ProtectedData`, validate that the request is from an authorized device,
+check that the request is fresh and verify and extract the MAC key. That backend
+component never sees any data related to the keys to be signed, but can provide
+the MAC key to another backend component that can verify `MacedKeysToSign` and
+proceed to generate the certificates.
+
+In this way, we can partition the provisioning server into one component that
+knows the device identity, as represented by DK\_pub, but never sees the keys to
+be certified or certificates generated, and another component that sees the keys
+to be certified and certificates generated but does not know the device
+identity.
+
+### Key and cryptographic message formatting
+
+For simplicity of generation and parsing, compactness of wire representation,
+and flexibility and standardization, we've settled on using the CBOR Object
+Signing and Encryption (COSE) standard, defined in [RFC
+8152](https://tools.ietf.org/html/rfc8152). COSE provides compact and reasonably
+simple, yet easily-extensible, wire formats for:
+
+*   Keys,
+*   MACed messages,
+*   Signed messages, and
+*   Encrypted messages
+
+COSE enables easy layering of these message formats, such as using a COSE\_Sign
+structure to contain a COSE\_Key with a public key in it. We call this a
+"certificate".
+
+Due to the complexity of the standard, we'll spell out the COSE structures
+completely in this document and in the HAL and other documentation, so that
+although implementors will need to understand CBOR and the CBOR Data Definition
+Language ([CDDL, defined in RFC 8610](https://tools.ietf.org/html/rfc8610)),
+they shouldn't need to understand COSE.
+
+Note, however, that the certificate chains returned from the provisioning server
+are standard X.509 certificates.
+
+### Algorithm choices
+
+This document uses:
+
+*   ECDSA P-256 for attestation signing keys;
+*   Remote provisioning protocol signing keys:
+  *  Ed25519 / P-256
+*   ECDH keys:
+  *  X25519 / P-256
+*   AES-GCM for all encryption;
+*   SHA-256 for all message digesting;
+*   HMAC-SHA-256 for all MACing; and
+*   HKDF-SHA-256 for all key derivation.
+
+We believe that Curve25519 offers the best tradeoff in terms of security,
+efficiency and global trustworthiness, and that it is now sufficiently
+widely-used and widely-implemented to make it a practical choice.
+
+However, since Secure Elements (SE) do not currently offer support for curve
+25519, we are allowing implementations to instead make use of EC P-256 for
+signing and ECDH. To put it simply, the device unique key pair will be a P-256
+key pair for ECDSA instead of Ed25519, and the ProtectedData COSE\_Encrypt
+message will have its payload encrypted with P-256 ECDH key exchange instead of
+X25519.
+
+The CDDL in the rest of the document will use the '/' operator to show areas
+where either curve 25519 or P-256 may be used. Since there is no easy way to
+bind choices across different CDDL groups, it is important that the implementor
+stays consistent in which type is chosen. E.g. taking ES256 as the choice for
+algorithm implies the implementor should also choose the P256 public key group
+further down in the COSE structure.
+
+### Testability
+
+It's critical that the remote provisioning implementation be testable, to
+minimize the probability that broken devices are sold to end users. To support
+testing, the remote provisioning HAL methods take a `testMode` argument. Keys
+created in test mode are tagged to indicate this. The provisioning server will
+check for the test mode tag and issue test certificates that do not chain back
+to a trusted public key. In test mode, any EEK will be accepted, enabling
+testing tools to use EEKs for which they have the private key so they can
+validate the content of certificate requests. The BCC included in the
+`CertificateRequest` must contain freshly-generated keys, not the real BCC keys.
+
+Keystore (or similar) will need to be able to handle both testMode keys and
+production keys and keep them distinct, generating test certificate requests
+when asked with a test EEK and production certificate requests when asked with a
+production EEK. Likewise, the interface used to instruct Keystore to create keys
+will need to be able to specify whether test or production keys are desired.
+
+## Design
+
+### Certificate provisioning flow
+
+TODO(jbires): Replace this with a `.png` containing a sequence diagram.  The
+provisioning flow looks something like this:
+
+Provisioner -> Keystore: Prepare N keys
+Keystore -> KeyMint: generateKeyPair
+KeyMint -> KeyMint: Generate  key pair
+KeyMint --> Keystore: key\_blob,pubkey
+Keystore -> Keystore: Store key\_blob,pubkey
+Provisioner -> Server: Get TEEK
+Server --> Provisioner: TEEK
+Provisioner -> Keystore: genCertReq(N, TEEK)
+Keystore -> KeyMint: genCertReq(pubkeys, TEEK)
+KeyMint -> KeyMint: Sign pubkeys & encrypt BCC
+KeyMint --> Keystore: signature, encrypted BCC
+Keystore -> Keystore: Construct cert\_request
+Keystore --> Provisioner: cert\_request
+Provisioner --> Server: cert\_request
+Server -> Server: Validate cert\_request
+Server -> Server: Generate certificates
+Server --> Provisioner: certificates
+Provisioner -> Keystore: certificates
+Keystore -> Keystore: Store certificates
+
+The actors in the above diagram are:
+
+*   **Server** is the backend certificate provisioning server. It has access to
+    the uploaded device public keys and is responsible for providing encryption
+    keys, decrypting and validating requests, and generating certificates in
+    response to requests.
+*   **Provisioner** is an application that is responsible for communicating with
+    the server and all of the system components that require key certificates
+    from the server. It also implements the policy that defines how many key
+    pairs each client should keep in their pool.
+*   **Keystore** is the [Android keystore
+    daemon](https://developer.android.com/training/articles/keystore) (or, more
+    generally, whatever system component manages communications with a
+    particular secure aread component).
+*   **KeyMint** is the secure area component that manages cryptographic keys and
+    performs attestations (or perhaps some other secure area component).
+
+### `BCC`
+
+The _Boot Certificate Chain_ (BCC) is the chain of certificates that contains
+DK\_pub as well as other often device-unique certificates. The BCC is
+represented as a COSE\_Key containing DK\_pub followed by an array of
+COSE\_Sign1 "certificates" containing public keys and optional additional
+information, ordered from root to leaf, with each certificate signing the next.
+The first certificate in the array is signed by DK\_pub, the last certificate
+has the KeyMint (or whatever) signing key's public key, KM\_pub. In phase 1
+there is only one entry; DK\_pub and KM\_pub are the same key and the
+certificate is self-signed.
+
+Each COSE\_Sign1 certificate is a CBOR Web Token (CWT) as described in [RFC
+8392](https://tools.ietf.org/html/rfc8392) with additional fields as described
+in the Open Profile for DICE. Of these additional fields, only the
+_subjectPublicKey_ and _keyUsage_ fields are expected to be present for the
+KM\_pub entry (that is, the last entry) in a BCC, but all fields required by the
+Open Profile for DICE are expected for other entries (each of which corresponds
+to a particular firmware component or boot stage). The CWT fields _iss_ and
+_sub_ identify the issuer and subject of the certificate and are consistent
+along the BCC entries; the issuer of a given entry matches the subject of the
+previous entry.
+
+The BCC is designed to be constructed using the Open Profile for DICE. In this
+case the DK key pair is derived from the UDS as described by that profile and
+all BCC entries before the leaf are CBOR CDI certificates chained from DK\_pub.
+The KM key pair is not part of the derived DICE chain. It is generated (not
+derived) by the KeyMint module, certified by the last key in the DICE chain, and
+added as the leaf BCC entry. The key usage field in this leaf certificate must
+indicate the key is not used to sign certificates. If a UDS certificate is
+available on the device it should appear in the certificate request as the leaf
+of a DKCertChain in AdditionalDKSignatures (see
+[CertificateRequest](#certificaterequest)).
+
+The Open Profile for DICE allows for an arbitrary configuration descriptor. For
+BCC entries, this configuration descriptor is a CBOR map with the following
+optional fields. If no fields are relevant, an empty map should be encoded.
+Additional implementation-specific fields may be added using key values not in
+the range \[-70000, -70999\] (these are reserved for future additions here).
+
+```
+| Name              | Key    | Value type | Meaning                           |
+| ----------------- | ------ | ---------- | ----------------------------------|
+| Component name    | -70002 | tstr       | Name of firmware component / boot |
+:                   :        :            : stage                             :
+| Component version | -70003 | int        | Version of firmware component /   |
+:                   :        :            : boot stage                        :
+| Resettable        | -70004 | null       | If present, key changes on factory|
+:                   :        :            : reset                             :
+```
+
+Please see
+[ProtectedData.aidl](https://cs.android.com/android/platform/superproject/+/master:hardware/interfaces/security/rkp/aidl/android/hardware/security/keymint/ProtectedData.aidl)
+for a full CDDL definition of the BCC.
+
+### `CertificateRequest`
+
+The full CBOR message that will be sent to the server to request certificates
+is:
+
+```cddl
+CertificateRequest = [
+    DeviceInfo,
+    challenge : bstr,       // Provided by the server
+    ProtectedData,          // See ProtectedData.aidl
+    MacedKeysToSign         // See IRemotelyProvisionedComponent.aidl
+]
+
+DeviceInfo = [
+    VerifiedDeviceInfo,     // See DeviceInfo.aidl
+    UnverifiedDeviceInfo
+]
+
+// Unverified info is anything provided by the HLOS. Subject to change out of
+// step with the HAL.
+UnverifiedDeviceInfo = {
+    ? "fingerprint" : tstr,
+}
+
+```
+
+It will be the responsibility of Keystore and the Provisioner to construct the
+`CertificateRequest`. The HAL provides a method to generate the elements that
+need to be constructed on the secure side, which are the tag field of
+`MacedKeysToSign`, `VerifiedDeviceInfo`, and the ciphertext field of
+`ProtectedData`.
+
+### HAL
+
+The remote provisioning HAL provides a simple interface that can be implemented
+by multiple secure components that require remote provisioning. It would be
+slightly simpler to extend the KeyMint API, but that approach would only serve
+the needs of KeyMint, this is more general.
+
+NOTE the data structures defined in this HAL may look a little bloated and
+complex. This is because the COSE data structures are fully spelled-out; we
+could make it much more compact by not re-specifying the standardized elements
+and instead just referencing the standard, but it seems better to fully specify
+them. If the apparent complexity seems daunting, consider what the same would
+look like if traditional ASN.1 DER-based structures from X.509 and related
+standards were used and also fully elaborated.

+/**
+ * An IRemotelyProvisionedComponent is a secure-side component for which certificates can be
+ * remotely provisioned. It provides an interface for generating asymmetric key pairs and then
+ * creating a CertificateRequest that contains the generated public keys, plus other information to
+ * authenticate the request origin. The CertificateRequest can be sent to a server, which can
+ * validate the request and create certificates.
+ *
+ * This interface does not provide any way to use the generated and certified key pairs. It's
+ * intended to be implemented by a HAL service that does other things with keys (e.g. KeyMint).
+ *
+ * The root of trust for secure provisioning is something called the Device Identifier Composition
+ * Engine (DICE) Chain. The DICE Chain is a chain of certificates, represented as COSE_Sign1 objects
+ * containing CBOR Web Tokens (CWT) which have descriptions about the stage of firmware being
+ * signed, including a COSE_Key representation of that stage's public key.
+ *
+ * DICE Chain Design
+ * =================
+ *
+ * For a more exhaustive and thorough look at DICE and the implementation used within this protocol,
+ * please see: https://pigweed.googlesource.com/open-dice/+/HEAD/docs/specification.md
+ *
+ * The DICE Chain is designed to mirror the boot stages of a device, and to prove the content and
+ * integrity of each firmware image. In a proper DICE Chain, each boot stage hashes its own private
+ * key material with the code and any relevant configuration parameters of the next stage to produce
+ * a Compound Device Identifier, or CDI, which is used as the secret key material for the next
+ * stage. From the CDI, a key pair - CDI_*_Pub and CDI_*_Priv - is derived and certified for the
+ * next stage by the current stages CDI_*_Priv. The next stage is then loaded and given its CDI and
+ * the DICE certificate chain generated so far in a manner that does not leak the previous stage's
+ * CDI_*_Priv or CDI to later boot stages. The final, "leaf" CDI certificate contains a public key,
+ * denoted CDI_Leaf_Pub, whose corresponding private key, denoted CDI_Leaf_Priv, is available for
+ * use by the IRemotelyProvisionedComponent.
+ *
+ * The root keypair is generated by immutable code (e.g. ROM), from a Unique Device Secret (UDS).
+ * The keypair that is generated from it can be referred to as the UDS_Pub/UDS_Priv keys. After the
+ * device-unique secret is used, it must be made unavailable to any later boot stage.
+ *
+ * In this way, booting the device incrementally builds a certificate chain that (a) identifies and
+ * validates the integrity of every stage and (b) contains a set of public keys that correspond to
+ * private keys, one known to each stage. Any stage can compute the secrets of all later stages
+ * (given the necessary input), but no stage can compute the secret of any preceding stage. Updating
+ * the firmware or configuration of any stage changes the key pair of that stage, and of all
+ * subsequent stages, and no attacker who compromised the previous version of the updated firmware
+ * can know or predict the post-update key pairs. It is recommended and expected that the DICE Chain
+ * is constructed using the Open Profile for DICE.
+ *
+ * When the provisioning server receives a message signed by CDI_Leaf_Priv and containing a DICE
+ * chain that chains from UDS_Pub to CDI_Leaf_Pub, it can be certain that (barring vulnerabilities
+ * in some boot stage), the CertificateRequest came from the device associated with UDS_Pub, running
+ * the specific software identified by the certificates in the chain. If the server has some
+ * mechanism for knowing the hash values of compromised stages, it can determine whether signing
+ * certificates is appropriate.
+ *
+ * Degenerate DICE Chains
+ * ======================
+ *
+ * While a proper DICE Chain, as described above, reflects the complete boot sequence from boot ROM
+ * to the secure area image of the IRemotelyProvisionedComponent, it's also possible to use a
+ * "degenerate" DICE Chain which consists only of a single, self-signed certificate containing the
+ * public key of a hardware-bound key pair. This is an appropriate solution for devices which
+ * haven't implemented everything necessary to produce a proper DICE Chain, but can derive a unique
+ * key pair in the secure area. In this degenerate case, UDS_Pub is the same as CDI_Leaf_Pub.
+ *
+ * DICE Chain Privacy
+ * ==================
+ *
+ * Because the DICE Chain constitutes an unspoofable, device-unique identifier, special care is
+ * taken to prevent its availability to entities who may wish to track devices. Three precautions
+ * are taken:
+ *
+ * 1) The DICE chain is only handled by the native Remote Key Provisioning Daemon (RKPD) service on
+ *    the HLOS and is not exposed to apps running on device.
+ *
+ * 2) The CDI_Leaf_Priv key cannot be used to sign arbitrary data.
+ *
+ * 3) Backend infrastructure does not correlate UDS_Pub with the certificates signed and sent back
+ *    to the device.
+ *
+ * Versioning
+ * ==========
+ * Versions 1 and 2 of the schema, as previously defined in DeviceInfo.aidl, diverge in
+ * functionality from Version 3. Version 3 removes the need to have testMode in function calls and
+ * deprecates the Endpoint Encryption Key (EEK) as well. Vendors implementing Version 1
+ * (Android S/12) or Version 2 (Android T/13) do not need to implement generateCertificateRequestV2.
+ * Vendors implementing Version 3 (Android U/14) need to implement generateCertificateRequestV2.
+ *
+ * For better coverage of changes from version to version, please see RKP_CHANGELOG.md in the root
+ * of the keymint interface directory.

+// This file is a snapshot of an AIDL file. Do not edit it manually. There are
+// two cases:
+// 1). this is a frozen version file - do not edit this in any case.
+// 2). this is a 'current' file. If you make a backwards compatible change to
+//     the interface (from the latest frozen version), the build system will
+//     prompt you to update this file with `m <name>-update-api`.
+//
+// You must not make a backward incompatible change to any AIDL file built
+// with the aidl_interface module type with versions property set. The module
+// type is used to build AIDL files in a way that they can be used across
+// independently updatable components of the system. If a device is shipped
+// with such a backward incompatible change, it has a high risk of breaking
+// later when a module using the interface is updated, e.g., Mainline modules.

+     * different mode. Some HALs may only have a single mode, but an example where
+     * multiple modes would be required is if a chip has different firmwares with
+     * different capabilities.
+     *
+     * When in a mode, it must be possible to perform any combination of creating

+     * ChipConcurrencyCombinations is satisfied. This means that if a chip has two

+     * that exactly one STA type or one AP_BRIDGED type can be created, but it

+     * was then there would be a single available combination
+     * [{STA} <=1, {AP_BRIDGED} <= 1].
+     *
+     * When switching between two available combinations it is expected that
+     * interfaces only supported by the initial combination must be removed until
+     * the target combination is also satisfied. At that point new interfaces
+     * satisfying only the target combination can be added (meaning the initial
+     * combination limits will no longer satisfied). The addition of these new
+     * interfaces must not impact the existence of interfaces that satisfy both
+     * combinations.
+     *
+     * For example, a chip with available combinations:
+     *     [{STA} <= 2, {NAN} <=1] and [{STA} <=1, {NAN} <= 1, {AP_BRIDGED} <= 1}]
+     * If the chip currently has 3 interfaces STA, STA and NAN and wants to add an
+     * AP_BRIDGED interface in place of one of the STAs, then one of the STA interfaces
+     * must be removed first, and then the AP interface can be created after
+     * the STA has been torn down. During this process the remaining STA and NAN
+     * interfaces must not be removed/recreated.
+     *
+     * If a chip does not support this kind of reconfiguration in this mode then
+     * the combinations must be separated into two separate modes. Before
+     * switching modes, all interfaces must be torn down, the mode switch must be
+     * enacted, and when it completes the new interfaces must be brought up.
