+# Fuzzer for android.hardware.automotive.vehicle@2.0-manager-lib
+
+## Plugin Design Considerations
+The fuzzer plugin for android.hardware.automotive.vehicle@2.0-manager-lib is
+designed based on the understanding of the library and tries 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 fuzzer.
+
+Vehicle Manager supports the following parameters:
+1. Vehicle Property (parameter name: `vehicleProp`)
+2. Diagnostic Integer Sensor Index (parameter name: `diagnosticIntIndex`)
+3. Diagnostic Float Sensor Index (parameter name: `diagnosticFloatIndex`)
+4. Availability Message Type (parameter name: `availabilityMsgType`)
+5. Subscription Message Type (parameter name: `subscriptionMsgType`)
+
+| Parameter| Valid Values| Configured Value|
+|------------- |-------------| ----- |
+| `vehicleProp` | 0.`VehicleProperty::INVALID` 1.`VehicleProperty::HVAC_FAN_SPEED` 2.`VehicleProperty::INFO_MAKE` 3.`VehicleProperty::DISPLAY_BRIGHTNESS`  4.`VehicleProperty::INFO_FUEL_CAPACITY` 5.`VehicleProperty::HVAC_SEAT_TEMPERATURE`| Value obtained from FuzzedDataProvider |
+| `diagnosticIntIndex`   | 0.`DiagnosticIntegerSensorIndex::FUEL_SYSTEM_STATUS` 1.`DiagnosticIntegerSensorIndex::MALFUNCTION_INDICATOR_LIGHT_ON` 2.`DiagnosticIntegerSensorIndex::NUM_OXYGEN_SENSORS_PRESENT` 3.`DiagnosticIntegerSensorIndex::FUEL_TYPE`  | Value obtained from FuzzedDataProvider |
+| `diagnosticFloatIndex`   | 0.`DiagnosticFloatSensorIndex::CALCULATED_ENGINE_LOAD` 1.`DiagnosticFloatSensorIndex::SHORT_TERM_FUEL_TRIM_BANK1` 2.`DiagnosticFloatSensorIndex::LONG_TERM_FUEL_TRIM_BANK1` 3.`DiagnosticFloatSensorIndex::THROTTLE_POSITION`  | Value obtained from FuzzedDataProvider |
+| `availabilityMsgType`   | 0.`VmsMessageType::AVAILABILITY_CHANGE` 1.`VmsMessageType::AVAILABILITY_RESPONSE` | Value obtained from FuzzedDataProvider |
+| `subscriptionMsgType`   | 0.`VmsMessageType::SUBSCRIPTIONS_CHANGE` 1.`VmsMessageType::SUBSCRIPTIONS_RESPONSE` | Value obtained from FuzzedDataProvider |
+
+This also ensures that the plugin is always deterministic for any given input.
+
+## Build
+
+This describes steps to build vehicleManager_fuzzer binary.
+
+### Android
+
+#### Steps to build
+Build the fuzzer
+```
+  $ mm -j$(nproc) vehicleManager_fuzzer
+```
+
+#### Steps to run
+Create a directory CORPUS_DIR
+```
+  $ adb shell mkdir /data/local/tmp/CORPUS_DIR
+```
+
+##### Some Additional steps needed to run the vehicleManager_fuzzer successfully on device
+
+1. Push the following libraries from /vendor/lib/ and /vendor/lib64/ folders of your workspace to the device's /vendor/lib/ and /vendor/lib64/ :
+```
+1.1  android.hardware.automotive.vehicle@2.0.so
+1.2  carwatchdog_aidl_interface-V2-ndk_platform.so
+```
+2. Now, reboot the device using command
+```
+  $ adb reboot
+```
+
+##### To run the fuzzer on device
+```
+  $ adb sync data
+  $ adb shell LD_LIBRARY_PATH=/vendor/lib64 /data/fuzz/${TARGET_ARCH}/vehicleManager_fuzzer/vendor/vehicleManager_fuzzer /data/local/tmp/CORPUS_DIR
+```
