+// Stability encodes how a binder changes over time. There are two levels of
+// stability:
+// 1). the interface stability - this is how a particular set of API calls (a
+//   particular ordering of things like writeInt32/readInt32) are changed over
+//   time. If one release, we have 'writeInt32' and the next release, we have
+//   'writeInt64', then this interface doesn't have a very stable
+//   Stability::Level. Usually this ordering is controlled by a .aidl file.
+// 2). the wire format stability - this is how these API calls map to actual
+//   bytes that are written to the wire (literally, this is how they are written
+//   to the kernel inside of IBinder::transact, but it may be expanded to other
+//   wires in the future). For instance, writeInt32 in binder translates to
+//   writing a 4-byte little-endian integer in two's complement. You can imagine
+//   in the future, we change writeInt32/readInt32 to instead write 8-bytes with
+//   that integer and some check bits. In this case, the wire format changes,
+//   but as long as a client libbinder knows to keep on writing a 4-byte value
+//   to old servers, and new servers know how to interpret the 8-byte result,
+//   they can still communicate.
+//
+// Every binder object has a stability level associated with it, and when
+// communicating with a binder, we make sure that the command we sent is one
+// that it knows how to process. The summary of stability of a binder is
+// represented by a Stability::Category object.

+# Fuzzer for libvibrator
+
+## Plugin Design Considerations
+This fuzzer fuzzes native code present in libvibrator and does not cover the Java implementation ExternalVibration
+The fuzzer plugin 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.
+
+libvibrator supports the following parameters:
+1. Uid (parameter name: `uid`)
+2. Package Name (parameter name: `pkg`)
+3. Audio Content Type (parameter name: `content_type`)
+4. Audio Usage (parameter name: `usage`)
+5. Audio Source (parameter name: `source`)
+6. Audio flags (parameter name: `flags`)
+
+| Parameter| Valid Values| Configured Value|
+|------------- |-------------| ----- |
+| `uid` | `INT32_MIN` to `INT32_MAX` | Value obtained from FuzzedDataProvider |
+| `pkg`   | Any std::string value | Value obtained from FuzzedDataProvider |
+| `content_type`   | 0.`AUDIO_CONTENT_TYPE_UNKNOWN` 1.`AUDIO_CONTENT_TYPE_SPEECH` 2.`AUDIO_CONTENT_TYPE_MUSIC` 3.`AUDIO_CONTENT_TYPE_MOVIE` 4.`AUDIO_CONTENT_TYPE_SONIFICATION`| Value obtained from FuzzedDataProvider in the range 0 to 4|
+| `usage`   | 0.`AUDIO_USAGE_UNKNOWN` 1.`AUDIO_USAGE_MEDIA` 2.`AUDIO_USAGE_VOICE_COMMUNICATION` 3.`AUDIO_USAGE_VOICE_COMMUNICATION_SIGNALLING` 4.`AUDIO_USAGE_ALARM` 5.`AUDIO_USAGE_NOTIFICATION` 6.`AUDIO_USAGE_NOTIFICATION_TELEPHONY_RINGTONE`  7.`AUDIO_USAGE_NOTIFICATION_COMMUNICATION_REQUEST` 8.`AUDIO_USAGE_NOTIFICATION_COMMUNICATION_INSTANT` 9.`AUDIO_USAGE_NOTIFICATION_COMMUNICATION_DELAYED` 10.`AUDIO_USAGE_NOTIFICATION_EVENT` 11.`AUDIO_USAGE_ASSISTANCE_ACCESSIBILITY` 12.`AUDIO_USAGE_ASSISTANCE_NAVIGATION_GUIDANCE` 13.`AUDIO_USAGE_ASSISTANCE_SONIFICATION` 14.`AUDIO_USAGE_GAME` 15.`AUDIO_USAGE_VIRTUAL_SOURCE` 16.`AUDIO_USAGE_ASSISTANT` 17.`AUDIO_USAGE_CALL_ASSISTANT` 18.`AUDIO_USAGE_EMERGENCY` 19.`AUDIO_USAGE_SAFETY` 20.`AUDIO_USAGE_VEHICLE_STATUS` 21.`AUDIO_USAGE_ANNOUNCEMENT`| Value obtained from FuzzedDataProvider in the range 0 to 21|
+| `source`   |  0.`AUDIO_SOURCE_DEFAULT` 1.`AUDIO_SOURCE_MIC` 2.`AUDIO_SOURCE_VOICE_UPLINK` 3.`AUDIO_SOURCE_VOICE_DOWNLINK` 4.`AUDIO_SOURCE_VOICE_CALL` 5.`AUDIO_SOURCE_CAMCORDER` 6.`AUDIO_SOURCE_VOICE_RECOGNITION` 7.`AUDIO_SOURCE_VOICE_COMMUNICATION` 8.`AUDIO_SOURCE_REMOTE_SUBMIX` 9.`AUDIO_SOURCE_UNPROCESSED` 10.`AUDIO_SOURCE_VOICE_PERFORMANCE` 11.`AUDIO_SOURCE_ECHO_REFERENCE` 12.`AUDIO_SOURCE_FM_TUNER` | Value obtained from FuzzedDataProvider in the range 0 to 12 |
+| `flags`   | `UINT32_MIN` to `UINT32_MAX` | Value obtained from FuzzedDataProvider |
+
+This also ensures that the plugin is always deterministic for any given input.
+
+##### Maximize utilization of input data
+The plugin tolerates any kind of input (empty, huge,
+malformed, etc) and doesn't `exit()` on any input and thereby increasing the
+chance of identifying vulnerabilities.
+
+## Build
+
+This describes steps to build vibrator_fuzzer binary.
+
+### Android
+
+#### Steps to build
+Build the fuzzer
+```
+  $ mm -j$(nproc) vibrator_fuzzer
+```
+
+#### Steps to run
+Create a directory CORPUS_DIR and copy some files to that folder
+Push this directory to device.
+
+To run on device
+```
+  $ adb sync data
+  $ adb shell /data/fuzz/arm64/vibrator_fuzzer/vibrator_fuzzer CORPUS_DIR
+```
+
+To run on host
+```
+  $ $ANDROID_HOST_OUT/fuzz/x86_64/vibrator_fuzzer/vibrator_fuzzer CORPUS_DIR
+```
