+        This contains both permanently attached devices and removable devices.
+        “mixPorts”: listing all output and input streams exposed by the audio HAL
+        “routes”: list of possible connections between input and output devices or between stream and
+        devices.
+            "route": is defined by an attribute:
+                -"type": <mux|mix> means all sources are mutual exclusive (mux) or can be mixed (mix)

+        “attachedDevices”: permanently attached devices.
+        The attachedDevices section is a list of devices names. The names correspond to device names
+        defined in <devicePorts> section.

+                “primary”, “A2DP”, “remote_submix”, “USB”
+        Each module will contain the following sections:
+        “devicePorts”: a list of device descriptors for all input and output devices accessible via this
+        module.
+        This contains both permanently attached devices and removable devices.
+        “mixPorts”: listing all output and input streams exposed by the audio HAL
+        “routes”: list of possible connections between input and output devices or between stream and
+        devices.
+            "route": is defined by an attribute:
+                -"type": <mux|mix> means all sources are mutual exclusive (mux) or can be mixed (mix)
+                -"sink": the sink involved in this route
+                -"sources": all the sources than can be connected to the sink via vis route
+        “attachedDevices”: permanently attached devices.
+        The attachedDevices section is a list of devices names. The names correspond to device names
+        defined in <devicePorts> section.
+        “defaultOutputDevice”: device to be used by default when no policy rule applies

+                “primary”, “A2DP”, “remote_submix”, “USB”
+        Each module will contain the following sections:
+        “devicePorts”: a list of device descriptors for all input and output devices accessible via this
+        module.
+        This contains both permanently attached devices and removable devices.
+        “mixPorts”: listing all output and input streams exposed by the audio HAL
+        “routes”: list of possible connections between input and output devices or between stream and
+        devices.
+            "route": is defined by an attribute:
+                -"type": <mux|mix> means all sources are mutual exclusive (mux) or can be mixed (mix)
+                -"sink": the sink involved in this route
+                -"sources": all the sources than can be connected to the sink via vis route
+        “attachedDevices”: permanently attached devices.
+        The attachedDevices section is a list of devices names. The names correspond to device names
+        defined in <devicePorts> section.
+        “defaultOutputDevice”: device to be used by default when no policy rule applies

+     *  temperature control units -- driver side and passenger side.
+     *   - A valid mapping set of AreaIDs for HVAC_TEMPERATURE_SET would be a
+     *     two element array:
+     *      - ROW_1_LEFT  | ROW_2_LEFT
+     *      - ROW_1_RIGHT | ROW_2_CENTER | ROW_2_RIGHT

+     *      - ROW_1_RIGHT | ROW_2_RIGHT
+     *  The temperature controllers are assigned to the seats which they
+     *  "most influence", but every seat must be included exactly once. The
+     *  assignment of the center rear seat to the left or right AreaID may seem
+     *  arbitrary, but the inclusion of every seat in exactly one AreaID ensures
+     *  that the seats in the car are all expressed and that a "reasonable" way

+     *
+     * Example 2: A car has three seat rows with two seats in the front row (ROW_1_LEFT,

+     * Note that the property may take >0 ms to get propagated through the stack

+     * 1.LEGACY_ANDROID_SWITCH
+     * -----------------------
+     *
+     * Called by the Android System to indicate the Android user is about to change, when the change
+     * request was made in a way that is not integrated with the HAL (for example, through
+     * adb shell am switch-user).
+     *
+     * The HAL can switch its internal user once it receives this request, but it doesn't need to
+     * reply back to the Android System. If its internal user cannot be changed for some reason,
+     * then it must wait for the SWITCH_USER(type=ANDROID_POST_SWITCH) call to recover
+     * (for example, it could issue a SWITCH_USER(type=VEHICLE_REQUEST) to switch back to
+     * the previous user), but ideally it should never fail (as switching back could result in a
+     * confusing experience for the end user).
+     *
+     * For example, if the system have users (0, 10, 11) and it's switching from 0 to 11 (where none
+     * of them have any special flag), the request would be:
+     *
+     * int32[0]:  42  // request id
+     * int32[1]:  1   // SwitchUserMessageType::LEGACY_ANDROID_SWITCH
+     * int32[2]:  11  // target user id
+     * int32[3]:  0   // target user flags (none)
+     * int32[4]:  10  // current user
+     * int32[5]:  0   // current user flags (none)
+     * int32[6]:  3   // number of users
+     * int32[7]:  0   // user #0 (Android user id 0)
+     * int32[8]:  0   // flags of user #0 (none)
+     * int32[9]:  10  // user #1 (Android user id 10)
+     * int32[10]: 0   // flags of user #1 (none)
+     * int32[11]: 11  // user #2 (Android user id 11)
+     * int32[12]: 0   // flags of user #2 (none)
+     *
+     * 2.ANDROID_SWITCH
+     * ----------------
+     * Called by the Android System to indicate the Android user is about to change, but Android
+     * will wait for the HAL's response (up to some time) before proceeding.
+     *
+     * The HAL must switch its internal user once it receives this request, then respond back to
+     * Android with a SWITCH_USER(type=VEHICLE_RESPONSE) indicating whether its internal
+     * user was switched or not (through the SwitchUserStatus enum).
+     *
+     * For example, if Android has users (0, 10, 11) and it's switching from 10 to 11 (where
+     * none of them have any special flag), the request would be:
+     *
+     * int32[0]:  42  // request id
+     * int32[1]:  2   // SwitchUserMessageType::ANDROID_SWITCH
+     * int32[2]:  11  // target user id
+     * int32[3]:  0   // target user flags (none)
+     * int32[4]:  10  // current user
+     * int32[5]:  0   // current user flags (none)
+     * int32[6]:  3   // number of users
+     * int32[7]:  0   // 1st user (user 0)
+     * int32[8]:  1   // 1st user flags (SYSTEM)
+     * int32[9]:  10  // 2nd user (user 10)
+     * int32[10]: 0   // 2nd user flags (none)
+     * int32[11]: 11  // 3rd user (user 11)
+     * int32[12]: 0   // 3rd user flags (none)
+     *
+     * If the request succeeded, the HAL must update the property with:
+     *
+     * int32[0]: 42  // request id
+     * int32[1]: 3   // messageType = SwitchUserMessageType::VEHICLE_RESPONSE
+     * int32[2]: 1   // status = SwitchUserStatus::SUCCESS
+     *
+     * But if it failed, the response would be something like:
+     *
+     * int32[0]: 42   // request id
+     * int32[1]: 3    // messageType = SwitchUserMessageType::VEHICLE_RESPONSE
+     * int32[2]: 2    // status = SwitchUserStatus::FAILURE
+     * string: "108-D'OH!" // OEM-specific error message
+     *
+     * 3.VEHICLE_RESPONSE
+     * ------------------
+     * Called by the HAL to indicate whether a request of type ANDROID_SWITCH should proceed or
+     * abort - see the ANDROID_SWITCH section above for more info.
+     *
+     * 4.VEHICLE_REQUEST
+     * ------------------
+     * Called by the HAL to request that the current foreground Android user is switched.
+     *
+     * This is useful in situations where Android started as one user, but the vehicle identified
+     * the driver as another user. For example, user A unlocked the car using the key fob of user B;
+     * the INITIAL_USER_INFO request returned user B, but then a face recognition subsubsystem
+     * identified the user as A.
+     *
+     * The HAL makes this request by a property change event (passing a negative request id), and
+     * the Android system will response by issue an ANDROID_POST_SWITCH call which the same
+     * request id.
+     *
+     * For example, if the current foreground Android user is 10 and the HAL asked it to switch to
+     * 11, the request would be:
+     *
+     * int32[0]: -108  // request id
+     * int32[1]: 4     // messageType = SwitchUserMessageType::VEHICLE_REQUEST
+     * int32[2]: 11    // Android user id
+     *
+     * If the request succeeded and Android has 3 users (0, 10, 11), the response would be:
+     *
+     * int32[0]: -108 // request id
+     * int32[1]:  5   // messageType = SwitchUserMessageType::ANDROID_POST_SWITCH
+     * int32[2]:  11  // target user id
+     * int32[3]:  0   // target user id flags (none)
+     * int32[4]:  11  // current user
+     * int32[5]:  0   // current user flags (none)
+     * int32[6]:  3   // number of users
+     * int32[7]:  0   // 1st user (user 0)
+     * int32[8]:  0   // 1st user flags (none)
+     * int32[9]:  10  // 2nd user (user 10)
+     * int32[10]: 4   // 2nd user flags (none)
+     * int32[11]: 11  // 3rd user (user 11)
+     * int32[12]: 3   // 3rd user flags (none)
+     *
+     * Notice that both the current and target user ids are the same - if the request failed, then
+     * they would be different (i.e, target user would be 11, but current user would still be 10).
+     *
+     * 5.ANDROID_POST_SWITCH
+     * ---------------------
+     * Called by the Android System after a request to switch a user was made.
+     *
+     * This property is called after switch requests of any type (i.e., LEGACY_ANDROID_SWITCH,
+     * ANDROID_SWITCH, or VEHICLE_REQUEST) and can be used to determine if the request succeeded or
+     * failed:
+     *
+     * 1. When it succeeded, it's called when the Android user is in the unlocked state and the
+     *    value of the current and target users ids in the response are the same. This would be
+     *    equivalent to receiving an Intent.ACTION_USER_UNLOCKED in an Android app.
+     * 2. When it failed it's called right away and the value of the current and target users ids
+     *    in the response are different (as the current user didn't change to the target).
+     * 3. If a new switch request is made before the HAL responded to the previous one or before
+     *    the user was unlocked, then the ANDROID_POST_SWITCH request is not made. For example,
+     *    the driver could accidentally switch to the wrong user which has lock credentials, then
+     *    switch to the right one before entering the credentials.
+     *
+     * The HAL can update its internal state once it receives this request, but it doesn't need to
+     * reply back to the Android System.
+     *
+     * Request: the first N values as defined by INITIAL_USER_INFO (where the request-specific
+     * value at index 1 is SwitchUserMessageType::ANDROID_POST_SWITCH), then 2 more values for the
+     * target user id (i.e., the Android user id that was requested to be switched to) and its flags
+     * (as defined by  UserFlags).
+     *
+     * Response: none.
+     *
+     * Example: see VEHICLE_REQUEST section above.

+     *
+     * To query the association, the Android system gets the property, passing a VehiclePropValue
+     * containing the types of associations are being queried, as defined by

+     * VehiclePropValue is defined by UserIdentificationResponse) indicating the current status of
+     * the types after the request.
+     *
+     * For example, to query if the current user (10) is associated with the FOB that unlocked the
+     * car and a custom mechanism provided by the OEM, the request would be:
+     *
+     * int32[0]: 42  // request id
+     * int32[1]: 10  (Android user id)
+     * int32[2]: 0   (Android user flags)
+     * int32[3]: 2   (number of types queried)
+     * int32[4]: 1   (1st type queried, UserIdentificationAssociationType::KEY_FOB)
+     * int32[5]: 101 (2nd type queried, UserIdentificationAssociationType::CUSTOM_1)
+     *
+     * If the user is associated with the FOB but not with the custom mechanism, the response would
+     * be:
+     *
+     * int32[0]: 42  // request id
+     * int32[1]: 2   (number of associations in the response)
+     * int32[2]: 1   (1st type: UserIdentificationAssociationType::KEY_FOB)
+     * int32[3]: 2   (1st value: UserIdentificationAssociationValue::ASSOCIATED_CURRENT_USER)

+     * int32[5]: 4   (2nd value: UserIdentificationAssociationValue::NOT_ASSOCIATED_ANY_USER)
+     *
+     * Then to associate the user with the custom mechanism, a set request would be made:
+     *
+     * int32[0]: 43  // request id
+     * int32[1]: 10  (Android user id)
+     * int32[2]: 0   (Android user flags)

+     * int32[5]: 1   (1st value: UserIdentificationAssociationSetValue::ASSOCIATE_CURRENT_USER)
+     *
+     * If the request succeeded, the response would be simply:
+     *

+# Fuzzer for android.hardware.bluetooth@1.0-impl-test
+
+## Plugin Design Considerations
+The fuzzer plugin for android.hardware.bluetooth@1.0-impl-test is designed based on the understanding of the source code and tries to achieve the following:
+
+##### Maximize code coverage
+1. The configuration parameters are not hardcoded, but instead selected based on
+incoming data. This ensures more code paths are reached by the fuzzer.
+
+2. A new library *'libbt-vendor-fuzz.so'* is created that implements functions of `bt_vendor_interface_t` and calls them in order to maximize the code coverage
+
+android.hardware.bluetooth@1.0-impl-test supports the following parameters:
+
+1. Bluetooth Address (parameter name: `btAddress`)
+
+| Parameter| Valid Values| Configured Value|
+|------------- |-------------| ----- |
+| `btAddress` | Values inside array ranges from `0x0` to `0xFF`| Value obtained from FuzzedDataProvider|
+
+This also ensures that the plugin is always deterministic for any given input.
+
+##### Maximize utilization of input data
+The plugin feeds the entire input data to the module.
+This ensures that the plugin tolerates any kind of input (empty, huge,
+malformed, etc) and doesnt `exit()` on any input and thereby increasing the
+chance of identifying vulnerabilities.
+
+## Build
+
+This describes steps to build bluetoothV1.0_fuzzer binary.
+
+### Android
+
+#### Steps to build
+Build the fuzzer
+```
+  $ mm -j$(nproc) bluetoothV1.0_fuzzer
+```
+#### Steps to run
+To run on device
+```
+  $ adb sync data
+  $ adb shell LD_LIBRARY_PATH=/data/fuzz/${TARGET_ARCH}/lib/ /data/fuzz/${TARGET_ARCH}/bluetoothV1.0_fuzzer/bluetoothV1.0_fuzzer
+```

+// 2). this is a 'current' file. If you make a backwards compatible change to

+//
+// 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

+ *
+ * Inside state: We are 95% confident that the user is inside the geofence.
+ * Outside state: We are 95% confident that the user is outside the geofence
+ * Unknown state: Rest of the time.
+ *
+ * The Unknown state is better explained with an example:
+ *
+ *                            __________
+ *                           |         c|

+ *                            """"""""""
+ * In the diagram above, "a" and "b" are 2 geofences and "c" is the accuracy
+ * circle reported by the GNSS subsystem. Now with regard to "b", the system is
+ * confident that the user is outside. But with regard to "a" is not confident
+ * whether it is inside or outside the geofence. If the accuracy remains the
+ * same for a sufficient period of time, the UNCERTAIN transition must be
+ * triggered with the state set to Unknown. If the accuracy improves later, an
+ * appropriate transition must be triggered.  This "sufficient period of time"
+ * is defined by the parameter in the addGeofenceArea API.
+ * In other words, Unknown state can be interpreted as a state in which the
+ * GNSS subsystem isn't confident enough that the user is either inside or
+ * outside the Geofence. It moves to Unknown state only after the expiry of the
+ * timeout.
+ *
+ * The geofence callback needs to be triggered for the ENTERED and EXITED
+ * transitions, when the GNSS system is confident that the user has entered
+ * (Inside state) or exited (Outside state) the Geofence. An implementation
+ * which uses a value of 95% as the confidence is recommended. The callback
+ * must be triggered only for the transitions requested by the
+ * addGeofenceArea method.
+ *
+ * Even though the diagram and explanation talks about states and transitions,
+ * the callee is only interested in the transitions. The states are mentioned
+ * here for illustrative purposes.
+ *
+ * Startup Scenario: When the device boots up, if an application adds geofences,
+ * and then we get an accurate GNSS location fix, it needs to trigger the
+ * appropriate (ENTERED or EXITED) transition for every Geofence it knows about.
+ * By default, all the Geofences will be in the Unknown state.
+ *
+ * When the GNSS system is unavailable, gnssGeofenceStatusCb must be
+ * called to inform the upper layers of the same. Similarly, when it becomes
+ * available the callback must be called. This is a global state while the
+ * UNKNOWN transition described above is per geofence.
+ *
+ * An important aspect to note is that users of this API (framework), will use
+ * other subsystems like wifi, sensors, cell to handle Unknown case and
+ * hopefully provide a definitive state transition to the third party
+ * application. GNSS Geofence will just be a signal indicating what the GNSS
+ * subsystem knows about the Geofence.

+# Health AIDL HAL
+
+## Determine whether the example service implementation is sufficient {#determine}
+
+You need a custom implementation if any of the following is true:
+
+* You are migrating from a custom
+  [health 2.1 HIDL HAL implementation](../2.1/README.md).
+* System properties `ro.charger.enable_suspend` and/or `ro.charger.no_ui`
+  are set to a `true` value. See [below](#charger-sysprops).
+* The device supports offline charging mode, and the `service`
+  declaration with `class charger` in `init.rc` is different from the one
+  provided by the example implementation. See [below](#charger-init-rc).
+
+If the example HAL service is sufficient, [install it](#use-example). Otherwise,
+[implement a custom HAL service](#use-custom).
+
+### System properties for charger {#charger-sysprops}
+
+The health AIDL HAL service also provides functionalities of `charger`. As a
+result, the system charger at `/system/bin/charger` is deprecated.
+
+However, the health AIDL HAL service is not allowed to read `ro.charger.*`
+system properties. These properties include:
+* `ro.charger.enable_suspend`. If set, you need a custom health AIDL HAL
+  service. See [below](#charger-enable-suspend).
+* `ro.charger.no_ui`. If set, you need a custom health AIDL HAL service.
+  See [below](#charger-no-ui).
+* `ro.charger.draw_split_screen`. The system property is deprecated.
+* `ro.charger.draw_split_offset`. The system property is deprecated.
+* `ro.charger.disable_init_blank`. The system property is deprecated.
+
+If you need to set any of the deprecated system properties, contact
+[OWNERS](OWNERS).
+
+### Default `service` declaration for charger in `init.rc` {#charger-init-rc}
+
+See
+[android.hardware.health-service.example.rc](default/android.hardware.health-service.example.rc).
+
+Check the `service` declaration in your device-specific `init.rc` file that
+has `class charger`. Most likely, the declaration looks something like this
+(Below is an excerpt from Pixel 3):
+
+```text
+service vendor.charger /system/bin/charger
+    class charger
+    seclabel u:r:charger:s0
+    user system
+    group system wakelock input
+    capabilities SYS_BOOT
+    file /dev/kmsg w
+    file /sys/fs/pstore/console-ramoops-0 r
+    file /sys/fs/pstore/console-ramoops r
+    file /proc/last_kmsg r
+```
+
+Compare each line against the one provided by the example health AIDL HAL
+service in
+[android.hardware.health-service.example.rc](default/android.hardware.health-service.example.rc).
+Specifically:
+
+* You may ignore the `service` line. The name of the service does not matter.
+* If your service belongs to additional classes beside `charger`, you need a
+  custom health AIDL service.
+* Modify the `seclabel` line. Replace `charger` with `charger_vendor`.
+* If your service has a different `user` (not `system`), you need a custom
+  health AIDL service.
+* If your service belongs to additional `group`s beside
+  `system wakelock input`, you need a custom health AIDL service.
+* If your service requires additional capabilities beside `SYS_BOOT`,
+  you need a custom health AIDL service.
+* If your service requires additional `file`s to be opened prior to execution,
+  you need a custom health AIDL service.
+
+## Using the example health AIDL HAL service {#use-example}
+
+If you [determined](#determine) that the example health AIDL HAL service works
+for your device, install it with
+
+```mk
+PRODUCT_PACKAGES += \
+    android.hardware.health-service.example \
+    android.hardware.health-service.example_recovery \
+```
+
+Then, delete any existing `service` with `class charger` in your device-specific
+`init.rc` files, because
+[android.hardware.health-service.example.rc](default/android.hardware.health-service.example.rc)
+already contains an entry for charger.
+
+If your device supports charger mode and it has custom charger resources,
+[move charger resources to `/vendor`](#charger-res)
+
+## Implementing a custom health AIDL HAL service {#use-custom}
+
+### Override the `Health` class {#health-impl}
+
+See [`Health.h`](default/include/health-impl/Health.h) for its class
+declaration. Inherit the class to customize for your device.
+
+```c++
+namespace aidl::android::hardware::health {
+class HealthImpl : public Health {
+    // ...
+};
+} // namespace aidl::android::hardware::health
+int main(int, char**) {
+    // ...
+    auto binder = ndk::SharedRefBase::make<aidl::android::hardware::health::HealthImpl>(
+            "default", std::move(config));
+    // ...
+}
+```
+
+* The logic to modify `healthd_config`, traditionally in `healthd_board_init()`
+  should be called before passing the `healthd_config` struct to your
+  `HealthImpl` class in [`main()`](#main).
+
+* The following functions are similar to the ones in the health 2.1 HIDL HAL:
+
+| AIDL implementation                 | HIDL implementation         |
+|-------------------------------------|-----------------------------|
+| `Health::getChargeCounterUah`       | `Health::getChargeCounter`  |
+| `Health::getCurrentNowMicroamps`    | `Health::getCurrentNow`     |
+| `Health::getCurrentAverageMicroamps`| `Health::getCurrentAverage` |
+| `Health::getCapacity`               | `Health::getCapacity`       |
+| `Health::getChargeStatus`           | `Health::getChargeStatus`   |
+| `Health::getEnergyCounterNwh`       | `Health::getEnergyCounter`  |
+| `Health::getDiskStats`              | `Health::getDiskStats`      |
+| `Health::getStorageInfo`            | `Health::getStorageInfo`    |
+| `Health::BinderEvent`               | `BinderHealth::BinderEvent` |
+| `Health::dump`                      | `Health::debug`             |
+| `Health::ShouldKeepScreenOn`        | `Health::shouldKeepScreenOn`|
+| `Health::UpdateHealthInfo`          | `Health::UpdateHealthInfo`  |
+
+### Implement `main()` {#main}
+
+See the [`main.cpp`](default/main.cpp) for the example health AIDL service for
+an example.
+
+If you need to modify `healthd_config`, do it before passing it to the
+constructor of `HealthImpl` (or `Health` if you did not implement a subclass
+of it).
+
+```c++
+int main(int argc, char** argv) {
+    auto config = std::make_unique<healthd_config>();
+    ::android::hardware::health::InitHealthdConfig(config.get());
+    healthd_board_init(config.get());
+    auto binder = ndk::SharedRefBase::make<Health>("default", std::move(config));
+    // ...
+}
+```
+
+If your device does not support off-line charging mode, or does not have a UI
+for charger (`ro.charger.no_ui=true`), skip the invocation of
+`ChargerModeMain()` in `main()`.
+
+### Build system changes
+
+Install both the platform and recovery variant of the service. For example:
+
+```mk
+PRODUCT_PACKAGES += \
+    android.hardware.health-service.cuttlefish \
+    android.hardware.health-service.cuttlefish_recovery \
+```
+
+### SELinux rules
+
+Add device specific permissions to the domain where the health HAL
+process is executed, especially if a device-specific `libhealthd` is used
+and/or device-specific storage related APIs are implemented.
+
+Example (assuming that your health AIDL service runs in domain
+`hal_health_tuna`:
+
+```text
+type hal_health_tuna, domain;
+hal_server_domain(hal_health_tuna, hal_health)
+type hal_health_tuna_exec, exec_type, vendor_file_type, file_type;
+
+# allow hal_health_tuna ...;
+```
+
+If you did not define a separate domain, the domain is likely
+`hal_health_default`. The device-specific rules for it is likely at
+`device/<manufacturer>/<device>/sepolicy/vendor/hal_health_default.te`.
+In this case, the aforementioned SELinux rules and types has already been
+defined. You only need to add device-specific permissions.
+
+```text
+# allow hal_health_default ...;
+```
+
+### Implementing charger {#charger}
+
+#### Move charger resources to `/vendor`
+
+Ensure that charger resources are installed to `/vendor`, not `/product`.
+
+`animation.txt` must be moved to the following location:
+
+```text
+/vendor/etc/res/values/charger/animation.txt
+```
+
+Charger resources in `/system` is not read by the health HAL service in
+`/vendor`. Specifically, resources should be installed to the following
+location:
+
+```
+/vendor/etc/res/images/charger/*.png
+```
+
+If resources are not found in these locations, the health HAL service falls
+back to the following locations:
+
+```
+/vendor/etc/res/images/charger/default/*.png
+```
+
+You can use the default resources by installing the default module:
+
+```makefile
+PRODUCT_PACKAGES += charger_res_images_vendor
+```
+
+#### Modify `init.rc` for charger
+
+It is recommended that you move the existing `service` entry with
+`class charger` to the `init.rc` file in your custom health service.
+
+Modify the entry to invoke the health service binary with `--charger` argument.
+See
+[android.hardware.health-service.example.rc](default/android.hardware.health-service.example.rc)
+for an example:
+
+```text
+service vendor.charger-tuna /vendor/bin/hw/android.hardware.health-service-tuna --charger
+    class charger
+    seclabel u:r:charger_vendor:s0
+    # ...
+```
+
+#### No charger mode {#no-charger}
+
+If your device does not support off-line charging mode, skip the invocation of
+`ChargerModeMain()` in `main()`.
+
+```c++
+int main(int, char**) {
+    // ...
+    // Skip checking if arguments contain "--charger"
+    auto hal_health_loop = std::make_shared<HalHealthLoop>(binder, binder);
+    return hal_health_loop->StartLoop();
+}
+```
+
+You may optionally delete the `service` entry with `class charger` in the
+`init.rc` file.
+
+#### No charger UI {#charger-no-ui}
+
+If your device does not have a UI for charger (`ro.charger.no_ui=true`), skip
+the invocation of `ChargerModeMain()` in `main()`.
+
+You may want to keep the `KernelLogger` so that charger still logs battery
+information to the kernel logs.
+
+```c++
+int main(int argc, char** argv) {
+    // ...
+    if (argc >= 2 && argv[1] == "--charger"sv) {
+        android::base::InitLogging(argv, &android::base::KernelLogger);
+        // fallthrough to HalHealthLoop::StartLoop()
+    }
+    auto hal_health_loop = std::make_shared<HalHealthLoop>(binder, binder);
+    return hal_health_loop->StartLoop();
+}
+```
+
+#### Enable suspend {#charger-enable-suspend}
+
+If your device has `ro.charger.enable_suspend=true`, implement a new class,
+`ChargerCallbackImpl`, that inherits from
+[`ChargerCallback`](default/include/health-impl/ChargerUtils.h). Then
+override the `ChargerEnableSuspend` function to return `true`. Then pass an
+instance of `ChargerCallbackImpl` to `ChargerModeMain()` instead.
+
+```c++
+namespace aidl::android::hardware::health {
+class ChargerCallbackImpl : public ChargerCallback {
+    bool ChargerEnableSuspend() override { return true; }
+};
+} // namespace aidl::android::hardware::health
+int main(int argc, char** argv) {
+    // ...
+    if (argc >= 2 && argv[1] == "--charger"sv) {
+        android::base::InitLogging(argv, &android::base::KernelLogger);
+#if !CHARGER_FORCE_NO_UI
+        return ChargerModeMain(binder,
+                std::make_shared<aidl::android::hardware::health::ChargerCallbackImpl>(binder));
+#endif
+    }
+    // ...
+}
+```
+
+#### SELinux rules for charger
+
+If your health AIDL service runs in a domain other than `hal_health_default`,
+add `charger_type` to it so the health HAL service can have charger-specific
+permissions. Example (assuming that your health AIDL service runs in domain
+`hal_health_tuna`:
+
+```text
+domain_trans(init, hal_health_tuna_exec, charger_vendor)
+```

+# Fuzzers for libkeymaster4support
+
+## Plugin Design Considerations
+The fuzzer plugins for libkeymaster4support are designed based on the understanding of the
+source code and try to achieve the following:
+
+##### Maximize code coverage
+The configuration parameters are not hardcoded, but instead selected based on
+incoming data. This ensures more code paths are reached by the fuzzers.
+
+libkeymaster4support supports the following parameters:
+1. Security Level (parameter name: `securityLevel`)
+2. Ec Curve (parameter name: `ecCurve`)
+3. Padding Mode (parameter name: `paddingMode`)
+4. Digest (parameter name: `digest`)
+5. Tag (parameter name: `tag`)
+
+| Parameter| Valid Values| Configured Value|
+|------------- |-------------| ----- |
+| `securityLevel` | 0.`SecurityLevel::SOFTWARE` 1.`SecurityLevel::TRUSTED_ENVIRONMENT` 2.`SecurityLevel::STRONGBOX`| Value obtained from FuzzedDataProvider|
+| `ecCurve` | 0.`EcCurve::P_224` 1.`EcCurve::P_256` 2.`EcCurve::P_384` 3. `EcCurve::P_521`| Value obtained from FuzzedDataProvider|
+| `paddingMode` | 0.`PaddingMode::NONE` 1.`PaddingMode::RSA_OAEP` 2.`PaddingMode::RSA_PSS` 3. `PaddingMode::RSA_PKCS1_1_5_ENCRYPT` 4.`PaddingMode::RSA_PKCS1_1_5_SIGN` 5.`PaddingMode::PKCS7`| Value obtained from FuzzedDataProvider|
+| `digest` | 1. `Digest::NONE` 2.`Digest::MD5` 3.`Digest::SHA1` 4.`Digest::SHA_2_224` 5.`Digest::SHA_2_256` 6.`Digest::SHA_2_384`  7.`Digest::SHA_2_512`| Value obtained from FuzzedDataProvider|
+| `tag` | 1. `Tag::INVALID` 2.`Tag::PURPOSE` 3.`Tag::ALGORITHM` 4.`Tag::KEY_SIZE` 5.`Tag::BLOCK_MODE` 6.`Tag::DIGEST` 7.`Tag::PADDING` 8.`Tag::CALLER_NONCE` 9.`Tag::MIN_MAC_LENGTH` 10.`Tag::EC_CURVE` 11.`Tag::RSA_PUBLIC_EXPONENT` 12.`Tag::INCLUDE_UNIQUE_ID` 13. `Tag::BLOB_USAGE_REQUIREMENTS` 14.`Tag::BOOTLOADER_ONLY` 15.`Tag::ROLLBACK_RESISTANCE` 16.`Tag::HARDWARE_TYPE` 17.`Tag::ACTIVE_DATETIME` 18. `Tag::ORIGINATION_EXPIRE_DATETIME` 19.`Tag::USAGE_EXPIRE_DATETIME` 20.`Tag::MIN_SECONDS_BETWEEN_OPS` 21.`Tag::MAX_USES_PER_BOOT` 22.`Tag::USER_ID` 23.` Tag::USER_SECURE_ID` 24.`Tag::NO_AUTH_REQUIRED` 25.`Tag::USER_AUTH_TYPE` 26.`Tag::AUTH_TIMEOUT` 27.`Tag::ALLOW_WHILE_ON_BODY` 28.`Tag::TRUSTED_USER_PRESENCE_REQUIRED` 29.`Tag::TRUSTED_CONFIRMATION_REQUIRED` 30.`Tag::UNLOCKED_DEVICE_REQUIRED` 31.`Tag::APPLICATION_ID` 32.`Tag::APPLICATION_DATA` 33.`Tag::CREATION_DATETIME` 34.`Tag::ORIGIN` 35.`Tag::ROOT_OF_TRUST` 36.`Tag::OS_VERSION` 37.`Tag::OS_PATCHLEVEL` 38.`Tag::UNIQUE_ID` 39.`Tag::ATTESTATION_CHALLENGE` 40.`Tag::ATTESTATION_APPLICATION_ID` 41.`Tag::ATTESTATION_ID_BRAND` 42.`Tag::ATTESTATION_ID_DEVICE` 43.`Tag::ATTESTATION_ID_PRODUCT` 44.`Tag::ATTESTATION_ID_SERIAL` 45.`Tag::ATTESTATION_ID_IMEI` 46.`Tag::ATTESTATION_ID_MEID` 47.`Tag::ATTESTATION_ID_MANUFACTURER` 48.`Tag::ATTESTATION_ID_MODEL` 49.`Tag::VENDOR_PATCHLEVEL` 50.`Tag::BOOT_PATCHLEVEL` 51.`Tag::ASSOCIATED_DATA` 52.`Tag::NONCE` 53.`Tag::MAC_LENGTH` 54.`Tag::RESET_SINCE_ID_ROTATION` 55.`Tag::CONFIRMATION_TOKEN`| Value obtained from FuzzedDataProvider|
+
+This also ensures that the plugins are always deterministic for any given input.
+
+##### Maximize utilization of input data
+The plugins feed the entire input data to the module.
+This ensures that the plugins tolerate any kind of input (empty, huge,
+malformed, etc) and dont `exit()` on any input and thereby increasing the
+chance of identifying vulnerabilities.
+
+## Build
+
+This describes steps to build keymaster4_attestation_fuzzer, keymaster4_authSet_fuzzer and keymaster4_utils_fuzzer binaries

+ * IExecution represents a reusable execution object with request and most other execution
+ * properties fixed. It is used to launch executions.
+ *
+ * At most one execution may occur on a reusable execution object at any given time, either by
+ * means of executeSynchronously or executeFenced.
+ *
+ * An IExecution object is used to control a set of executions on the same prepared model with
+ * the same request and properties. IExecution objects enable some optimizations:
+ * (1) An IExecution object can preserve resources between executions. For example, a driver can
+ *     map a memory object when the IExecution object is created and cache the mapping for reuse in
+ *     subsequent executions. Any cached resource can be released when the IExecution object is
+ *     destroyed.
+ * (2) Because an IExecution object may be used for at most one execution at a time, any transient
+ *     execution resources such as intermediate tensors can be allocated once when the IExecution
+ *     object is created and freed when the IExecution object is destroyed.
+ * (3) An IExecution object is created for a fixed request. This enables the implementation to apply
+ *     request-specific optimizations. For example, an implementation can avoid request validation
+ *     and conversions when the IExecution object is reused. An implementation may also choose to
+ *     specialize the dynamic tensor shapes in the IExecution object according to the request.

+//
+// 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

+     * framework of asynchronous events, such as a dynamic sensor connection.
+     *
+     * The Event FMQ is used to transport sensor events from the HAL to the
+     * framework. The Event FMQ is created using the eventQueueDescriptor.
+     * Data may only be written to the Event FMQ. Data must not be read from
+     * the Event FMQ since the framework is the only reader. Upon receiving
+     * sensor events, the HAL writes the sensor events to the Event FMQ.
+     *
+     * Once the HAL is finished writing sensor events to the Event FMQ, the HAL
+     * must notify the framework that sensor events are available to be read and
+     * processed. This is accomplished by either:
+     *     1) Calling the Event FMQ’s EventFlag::wake() function with
+     * EventQueueFlagBits::READ_AND_PROCESS
+     *     2) Setting the write notification in the Event FMQ’s writeBlocking()
+     *        function to EventQueueFlagBits::READ_AND_PROCESS.
+     *
+     * If the Event FMQ’s writeBlocking() function is used, the read
+     * notification must be set to EventQueueFlagBits::EVENTS_READ in order to
+     * be notified and unblocked when the framework has successfully read events
+     * from the Event FMQ.
+     *
+     * The Wake Lock FMQ is used by the framework to notify the HAL when it is
+     * safe to release its wake_lock. When the framework receives WAKE_UP events
+     * from the Event FMQ and the framework has acquired a wake_lock, the
+     * framework must write the number of WAKE_UP events processed to the Wake
+     * Lock FMQ. When the HAL reads the data from the Wake Lock FMQ, the HAL
+     * decrements its current count of unprocessed WAKE_UP events and releases
+     * its wake_lock if the current count of unprocessed WAKE_UP events is
+     * zero. It is important to note that the HAL must acquire the wake lock and
+     * update its internal state regarding the number of outstanding WAKE_UP
+     * events _before_ posting the event to the Wake Lock FMQ, in order to avoid
+     * a race condition that can lead to loss of wake lock synchronization with
+     * the framework.
+     *
+     * The framework must use the WAKE_LOCK_QUEUE_FLAG_BITS_DATA_WRITTEN value to
+     * notify the HAL that data has been written to the Wake Lock FMQ and must
+     * be read by HAL.
+     *
+     * The ISensorsCallback is used by the HAL to notify the framework of
+     * asynchronous events, such as a dynamic sensor connection.
+     *
+     * The name of any wake_lock acquired by the Sensors HAL for WAKE_UP events
+     * must begin with "SensorsHAL_WAKEUP".
+     *
+     * If WAKE_LOCK_TIMEOUT_SECONDS has elapsed since the most recent WAKE_UP
+     * event was written to the Event FMQ without receiving a message on the
+     * Wake Lock FMQ, then any held wake_lock for WAKE_UP events must be
+     * released.
+     *
+     * If either the Event FMQ or the Wake Lock FMQ is already initialized when
+     * initialize is invoked, then both existing FMQs must be discarded and the
+     * new descriptors must be used to create new FMQs within the HAL. The
+     * number of outstanding WAKE_UP events should also be reset to zero, and
+     * any outstanding wake_locks held as a result of WAKE_UP events should be
+     * released.
+     *
+     * All active sensor requests and direct channels must be closed and
+     * properly cleaned up when initialize is called in order to ensure that the
+     * HAL and framework's state is consistent (e.g. after a runtime restart).
+     *

+     *     X/Y plane being nominally parallel to the ground when the user is

+/**
+ * This is a quick-and-dirty sound trigger HAL console mock.
+ *
+ * It would only work on userdebug builds.
+ *
+ * When this app is started, it will initially:
+ * - Register a ISoundTriggerHw HAL with an instance name "mock".
+ * - Set a sysprop that tells SoundTriggerMiddlewareService to try to connect to the mock instance
+ * rather than the default one.
+ * - Reboot the real (default) HAL.
+ *
+ * In response to that, SoundTriggerMiddlewareService is going to connect to the mock HAL and resume
+ * normal operation.
+ *
+ * Our mock HAL will print to stdout every call it receives as well as expose a basic set of
+ * operations for sending event callbacks to the client. This allows us to simulate the frameworks
+ * behavior in response to different HAL behaviors.

+/**
+ * SoundTrigger HAL interface. Used for hardware recognition of hotwords
+ * and other sounds.
+ *
+ * Basic usage:
+ * ============
+ * ISoundTriggerHw supports the ability to have one of more  detection sessions running at a given
+ * time, and listening to acoustic events. The basic flow of setting up such a session is:
+ * - Load a model using loadSoundModel() or loadPhraseSoundModel(). The provided model object would
+ *   indicate the (implementation-specific) detection algorithm (engine) to use, as well as any
+ *   parameters applicable for this agorithm. Upon success, those methods would return a handle
+ *   which will be used to reference this model in subsequent calls.
+ * - Once the model had been successfully loaded, detection can begin by calling startRecognition().
+ * - Recognition will continue running in the background until one of the following events occurs:
+ *   - stopRecognition() has been called on this model.
+ *   - A detection has occurred.
+ *   - Detection was aborted, typically for resource constraints, for example, when a higher-
+ *     priority use-case has been initiated.
+ * - In the latter two cases, a recognition event will be sent via a the callback interface that was
+ *   registered by the client upon loading. In either case, after any of these events occur, the
+ *   detection becomes inactive and no more recognition callbacks are allowed.
+ * - The same model maybe started again at a later time, and this process may repeat as many times
+ *   as needed.
+ * - Finally, an inactive model that is no longer needed may be unloaded via unloadModel().
+ *
+ * Important notes about the threading model:
+ * ==========================================
+ * Both this interface and the corresponding callback interface use a synchronous calling
+ * convention. This model comes with some advantages, but also with some risks of deadlocks if the
+ * implementation does not handle this correctly. Please consider the following:
+ * - After stopRecognition() returns, no more recognition events for that model may be sent. This
+ *   implies that any queues holding such events must be flushed before the call returns and that
+ *   may imply that callback from the HAL to the client are done while stopRecognition() is blocked.
+ *   This is OK, and supported by the framework.
+ * - Similarly, the same relationship applies between unloadModel() and subsequent callbacks to
+ *   modelUnloaded().
+ * - Other than these two cases, calls into the HAL *MAY NOT* block on callbacks from the HAL, or
+ *   else deadlock conditions may result, which may be handled by rebooting of the HAL process and
+ *   cause service outages.
+ *
+ * Due to the asynchronous nature of recognition events and preemptive model unloading, the HAL must
+ * correctly handle requests that would have been valid before an event has been delivered, but
+ * became moot as result of the event. Namely:
+ * - stopRecognition() may be called on a model that has already delivered an event and became
+ *   inactive as a result. The HAL must return a successful return code in this case.
+ * - Furthermore, if a model is preemptively unloaded after it triggers (typically, this would
+ *   happen when it is first aborted and immediately preemptively unloaded), stopRecognition() may
+ *   be called on it. The HAL must return successfully in this case.
+ * - startRecognition() may be called on a model that has been preemptively unloaded. In this case,
+ *   the HAL must signal a ServiceSpecificException(RESOURCE_CONTENTION) to indicate that the
+ *   operation is temporarily unsuccessful.
+ * - unloadSoundModel() may be called on a model that has been preemptively unloaded. The HAL must
+ *   return a successful return code in this case. This also implies that model handles should
+ *   generally not be reused until explicitly unloaded. To avoid the rare possibility of running out
+ *   of handles, the framework may call unloadModel() on models that have been preemptively unloaded
+ *   by the HAL.
+ *
+ * Important notes about resource constraints and concurrency
+ * =========================================================
+ * Up until this version, the framework would enforce concurrency constraints expressed by the
+ * Properties presented by the soundtrigger instance. These include constraints on the maximum
+ * amount of models that can be loaded at the same time and on running recognition while capturing
+ * from the microphone.
+ * This version changes the approach for how these constraints are modeled, both offering the HAL
+ * implementation more flexibility and simplifying the framework's job in enforcing these
+ * limitations. Note that there is no change for how the framework behaves with earlier versions,
+ * everything described below only applies to this version and onward.
+ * The way this is achieved is as following:
+ * - The framework will no longer enforce constraints on concurrent loading of models, as expressed
+ *   in the Properties.maxSoundModels field (this property is merely a hint at this point and may be
+ *   deprecated in the future), or any other implicit constraints.
+ * - The framework will no longer enforce constraints on concurrency of audio recording and
+ *   soundtrigger operation, as expressed in the Properties.concurrentCapture field (this property
+ *   is merely a hint at this point and may be deprecated in the future).
+ * - The HAL implementation is free to reject loading of any model at any time by having the
+ *   respective load*() method signal a ServiceSpecificException(RESOURCE_CONTENTION).
+ * - The HAL implementation is free to reject starting of any model at any time by having the
+ *   respective start*() method signal a ServiceSpecificException(RESOURCE_CONTENTION).
+ * - The HAL implementation is free to preemptively stop a previously started model at its own
+ *   discretion (for example, if a higher priority use-case which cannot coexist with detection
+ *   has been requested). The HAL must notify the framework of the preemption by sending a
+ *   recognition event with an `ABORTED` status. The implementation must NOT attempt to restart the
+ *   recognition automatically when conditions change.
+ * - The HAL implementation is free to preemptively unload a previously loaded model at its own
+ *   discretion (for example, if a higher-priority model is being loaded and the two cannot
+ *   coexist). When doing so, it must first abort the detection if active (as per above) and then
+ *   notify the framework of the unload using the modelUnloaded() callback.
+ * - When conditions change, such that a model that couldn't previously load or start or that had
+ *   previously been preemptively stopped or unloaded, the HAL must notify the framework via the
+ *   newly added onResourcesAvailable() callback. This callback is not a guarantee that any
+ *   operation would now succeed, but merely a hint that retrying something that had previously
+ *   failed, now MAY succeed. Until this callback is invoked, the client may assume that any
+ *   operation that had previously failed or aborted would still fail if retried, so the
+ *   implementation should not forget to deliver it.
+ *   There are no guarantees regarding how the framework may respond to this event and the order in
+ *   which it may choose to reload/restart its models. Typically, as result of this event the
+ *   framework will make a single attempt per model to bring this model to its desired state
+ *   (loaded, started).

+ * - Register a ISoundTriggerHw HAL with an instance name "mock".
+ * - Set a sysprop that tells SoundTriggerMiddlewareService to try to connect to the mock instance
+ * rather than the default one.
+ * - Reboot the real (default) HAL.
+ *
+ * In response to that, SoundTriggerMiddlewareService is going to connect to the mock HAL and resume
+ * normal operation.
+ *
+ * Our mock HAL will print to stdout every call it receives as well as expose a basic set of
+ * operations for sending event callbacks to the client. This allows us to simulate the frameworks
+ * behavior in response to different HAL behaviors.

+The `android.hardware.uwb.fira_android` package is used to add any Android specific
+additions to the UCI specification defined by FIRA standards body. These
+additions should be added to the vendor specific portions carved out in the UCI
+specification.
+
+These include:
+ - Android specific GIDs/OIDs for commands/responses/notifications.
+ - Andriod specific params in an existing UCI specified command/response/notification.
+
+All other interactions sent/received over the HAL interface is expected to
+comply with the UCI specification that can be found [here](
+https://groups.firaconsortium.org/wg/Technical/document/folder/127).
+
+TODO([b/196004116](b/196004116)): Link to the published specification.

-/* The chip may either have a single mode supporting any number of combinations,
- * or a fixed dual-mode (so it involves firmware loading to switch between
- * modes) setting. If there is a need to support more modes, it needs to be
- * implemented manually in WiFi HAL (see changeFirmwareMode in
- * WifiChip::handleChipConfiguration).
- *
- * Supported combinations are defined in device's makefile, for example:
- *    WIFI_HAL_INTERFACE_COMBINATIONS := {{{STA, AP}, 1}, {{P2P, NAN}, 1}},
- *    WIFI_HAL_INTERFACE_COMBINATIONS += {{{STA}, 1}, {{AP}, 2}}
- * What means:
- *    Interface combination 1: 1 STA or AP and 1 P2P or NAN concurrent iface
- *                             operations.
- *    Interface combination 2: 1 STA and 2 AP concurrent iface operations.
- *
- * For backward compatibility, the following makefile flags can be used to
- * generate combinations list:
- *  - WIFI_HIDL_FEATURE_DUAL_INTERFACE
- *  - WIFI_HIDL_FEATURE_DISABLE_AP
- *  - WIFI_HIDL_FEATURE_AWARE
- * However, they are ignored if WIFI_HAL_INTERFACE_COMBINATIONS was provided.
- * With WIFI_HIDL_FEATURE_DUAL_INTERFACE flag set, there is a single mode with
- * two interface combinations:
- *    Interface Combination 1: Will support 1 STA and 1 P2P or NAN (optional)
- *                             concurrent iface operations.
- *    Interface Combination 2: Will support 1 STA and 1 AP concurrent
- *                             iface operations.
- *
- * The only dual-mode configuration supported is for alternating STA and AP
- * mode, that may involve firmware reloading. In such case, there are 2 separate
- * modes of operation with 1 interface combination each:
- *    Mode 1 (STA mode): Will support 1 STA and 1 P2P or NAN (optional)
- *                       concurrent iface operations.
- *    Mode 2 (AP mode): Will support 1 AP iface operation.
- *
- * If Aware is enabled, the iface combination will be modified to support either
- * P2P or NAN in place of just P2P.

+ * modes) setting. If there is a need to support more modes, it needs to be
+ * implemented manually in WiFi HAL (see changeFirmwareMode in
+ * WifiChip::handleChipConfiguration).
+ *
+ * Supported combinations are defined in device's makefile, for example:
+ *    WIFI_HAL_INTERFACE_COMBINATIONS := {{{STA, AP}, 1}, {{P2P, NAN}, 1}},
+ *    WIFI_HAL_INTERFACE_COMBINATIONS += {{{STA}, 1}, {{AP}, 2}}
+ * What means:
+ *    Interface combination 1: 1 STA or AP and 1 P2P or NAN concurrent iface
+ *                             operations.
+ *    Interface combination 2: 1 STA and 2 AP concurrent iface operations.
+ *
+ * For backward compatibility, the following makefile flags can be used to
+ * generate combinations list:
+ *  - WIFI_HIDL_FEATURE_DUAL_INTERFACE
+ *  - WIFI_HIDL_FEATURE_DISABLE_AP
+ *  - WIFI_HIDL_FEATURE_AWARE
+ * However, they are ignored if WIFI_HAL_INTERFACE_COMBINATIONS was provided.
+ * With WIFI_HIDL_FEATURE_DUAL_INTERFACE flag set, there is a single mode with
+ * two interface combinations:
+ *    Interface Combination 1: Will support 1 STA and 1 P2P or NAN (optional)
+ *                             concurrent iface operations.
+ *    Interface Combination 2: Will support 1 STA and 1 AP concurrent
+ *                             iface operations.
+ *
+ * The only dual-mode configuration supported is for alternating STA and AP
+ * mode, that may involve firmware reloading. In such case, there are 2 separate
+ * modes of operation with 1 interface combination each:
+ *    Mode 1 (STA mode): Will support 1 STA and 1 P2P or NAN (optional)
+ *                       concurrent iface operations.
+ *    Mode 2 (AP mode): Will support 1 AP iface operation.
+ *
+ * If Aware is enabled, the iface combination will be modified to support either
+ * P2P or NAN in place of just P2P.

+ * Netlink Interceptor
+ *
+ * This HAL provides a way for Android services to route their Netlink traffic to a location other

+ * -> Route Netlink traffic to a different host.
+ * -> Route Netlink traffic to a different VM.
+ * -> Convert Netlink commands into proprietary vendor hardware commands.
+ *
+ * Some important notes regarding Netlink Interceptor.
+ * -> All int values are treated as unsigned.
+ * -> Users of Netlink Interceptor must close their sockets with closeSocket manually.
+ * -> PID != process ID. In this case, it is "port ID", a unique number assigned by the kernel to a
+ *    given Netlink socket.
+ * -> Netlink PIDs are only unique per family. This means that for all NETLINK_GENERIC sockets,
+ *    there can only be one socket with PID "1234". HOWEVER, there can ALSO be a Netlink socket
+ *    using NETLINK_ROUTE which has a PID of "1234". Hence, in order to uniquely identify a Netlink
+ *    socket, both the PID and Netlink Family are required.
