+        This contains both permanently attached devices and removable devices.
+        “mixPorts”: listing all output and input streams exposed by the audio HAL

+        devices.
+            "route": is defined by an attribute:

+        “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

+# 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
+```

+# 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.
+* You may ignore the `seclabel` line. When the health AIDL service runs in
+  charger mode, its original SELinux domain is kept.
+* 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
+    # ...
+```
+
+#### 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
+type hal_health_tuna, charger_type, domain;
+hal_server_domain(hal_health_default, hal_health)
+```

+# 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

+     * getDataCallList() and dataCallListChanged().
+     * The Radio is expected to:
+     * - Create one data call context.
+     * - Create and configure a dedicated interface for the context.
+     * - The interface must be point to point.
+     * - The interface is configured with one or more addresses and is capable of sending and
+     *   receiving packets. The format is IP address with optional "/" prefix length (The format is
+     *   defined in RFC-4291 section 2.3). For example, "192.0.1.3", "192.0.1.11/16", or
+     *   "2001:db8::1/64". Typically one IPv4 or one IPv6 or one of each. If the prefix length is
+     *   absent, then the addresses are assumed to be point to point with IPv4 with prefix length 32
+     *   or IPv6 with prefix length 128.
+     * - Must not modify routing configuration related to this interface; routing management is
+     *   exclusively within the purview of the Android OS.
+     * - Support simultaneous data call context, with limits defined in the specifications. For LTE,
+     *   the max number of data calls is equal to the max number of EPS bearers that can be active.
+     *
+     * @param serial Serial number of request.
+     * @param accessNetwork The access network to setup the data call. If the data connection cannot
+     *        be established on the specified access network then this should respond with an error.
+     * @param dataProfileInfo Data profile info.
+     * @param roamingAllowed Indicates whether or not data roaming is allowed by the user.
+     * @param reason The request reason. Must be DataRequestReason:NORMAL or
+     *        DataRequestReason:HANDOVER.
+     * @param addresses If the reason is DataRequestReason:HANDOVER, this indicates the list of link
+     *        addresses of the existing data connection. This parameter must be ignored unless
+     *        reason is DataRequestReason:HANDOVER.
+     * @param dnses If the reason is DataRequestReason:HANDOVER, this indicates the list of DNS
+     *        addresses of the existing data connection. The format is defined in RFC-4291 section
+     *        2.2. For example, "192.0.1.3" or "2001:db8::1". This parameter must be ignored unless
+     *        reason is DataRequestReason:HANDOVER.
+     * @param pduSessionId The pdu session id to be used for this data call. A value of 0 means no
+     *        pdu session id was attached to this call. Reference: 3GPP TS 24.007 section 11.2.3.1b
+     * @param sliceInfo SliceInfo to be used for the data connection when a handover occurs from
+     *        EPDG to 5G. It is valid only when accessNetwork is AccessNetwork:NGRAN. If the slice
+     *        passed from EPDG is rejected, then the data failure cause must be
+     *        DataCallFailCause:SLICE_REJECTED.
+     * @param trafficDescriptor TrafficDescriptor for which data connection needs to be established.
+     *        It is used for URSP traffic matching as described in TS 24.526 Section 4.2.2.
+     *        It includes an optional DNN which, if present, must be used for traffic matching --
+     *        it does not specify the end point to be used for the data call. The end point is
+     *        specified by DataProfileInfo.apn; DataProfileInfo.apn must be used as the end point if
+     *        one is not specified through URSP rules.
+     * @param matchAllRuleAllowed bool to indicate if using default match-all URSP rule for this
+     *        request is allowed. If false, this request must not use the match-all URSP rule and if
+     *        a non-match-all rule is not found (or if URSP rules are not available) it should
+     *        return failure with cause DataCallFailCause:MATCH_ALL_RULE_NOT_ALLOWED. This is needed
+     *        as some requests need to have a hard failure if the intention cannot be met, for
