+# Fuzzer for libcmd_fuzzer
+
+## Plugin Design Considerations
+The fuzzer plugin for libcmd 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.
+
+libcmd supports the following parameters:
+1. In (parameter name: `in`)
+2. Out (parameter name: `out`)
+3. Err (parameter name: `err`)
+4. Run Mode (parameter name: `runMode`)
+
+| Parameter| Valid Values| Configured Value|
+|------------- |-------------| ----- |
+| `in` | `INT32_MIN` to `INT32_MAX` | Value obtained from FuzzedDataProvider|
+| `out` | `INT32_MIN` to `INT32_MAX` | Value obtained from FuzzedDataProvider|
+| `err` | `INT32_MIN` to `INT32_MAX` | Value obtained from FuzzedDataProvider|
+| `runMode` | 1.`RunMode::kStandalone` 2. `RunMode::kLibrary` | Value chosen from valid values using 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 cmd 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 cmd_fuzzer binary.
+
+### Android
+
+#### Steps to build
+Build the fuzzer
+```
+  $ mm -j$(nproc) cmd_fuzzer
+```
+#### Steps to run
+To run on device
+```
+  $ adb sync data
+  $ adb shell /data/fuzz/${TARGET_ARCH}/cmd_fuzzer/cmd_fuzzer
+```

- * A Session represents a group of threads with an inter-related workload such that hints for

- *
- * <p>Each session is expected to have a periodic workload with a target duration for each
- * cycle. The cycle duration is likely greater than the target work duration to allow other
- * parts of the pipeline to run within the available budget. For example, a renderer thread may
- * work at 60hz in order to produce frames at the display's frame but have a target work
- * duration of only 6ms.</p>
- *
- * <p>After each cycle of work, the client is expected to use
- * {@link APerformanceHint_reportActualWorkDuration} to report the actual time taken to
- * complete.</p>

+// This class embellishes a class with a few static methods which can be used in
+// limited circumstances (when one service needs to be registered and
+// published). However, this is an anti-pattern:
+// - these methods are aliases of existing methods, and as such, represent an
+//   incremental amount of information required to understand the system but
+//   which does not actually save in terms of lines of code. For instance, users
+//   of this class should be surprised to know that this will start up to 16
+//   threads in the binder threadpool.
+// - the template instantiation costs need to be paid, even though everything
+//   done here is generic.
+// - the getServiceName API here is undocumented and non-local (for instance,
+//   this unnecessarily assumes a single service type will only be instantiated
+//   once with no arguments).
+//
+// So, DO NOT USE.

-/**
- * Arguments for creating an effect that applies color transformations in linear XYZ space.
- * A linear effect is decomposed into the following steps when operating on an image:
- * 1. Electrical-Optical Transfer Function (EOTF) maps the input RGB signal into the intended
- * relative display brightness of the scene in nits for each RGB channel
- * 2. Transformation matrix from linear RGB brightness to linear XYZ, to operate on display
- * luminance.
- * 3. Opto-Optical Transfer Function (OOTF) applies a "rendering intent". This can include tone
- * mapping to display SDR content alongside HDR content, or any number of subjective transformations
- * 4. Transformation matrix from linear XYZ back to linear RGB brightness.
- * 5. Opto-Electronic Transfer Function (OETF) maps the display brightness of the scene back to
- * output RGB colors.
- *
- * For further reading, consult the recommendation in ITU-R BT.2390-4:
- * https://www.itu.int/dms_pub/itu-r/opb/rep/R-REP-BT.2390-4-2018-PDF-E.pdf
- *
- * Skia normally attempts to do its own simple tone mapping, i.e., the working color space is
- * intended to be the output surface. However, Skia does not support complex tone mapping such as
- * polynomial interpolation. As such, this filter assumes that tone mapping has not yet been applied
- * to the source colors. so that the tone mapping process is only applied once by this effect. Tone
- * mapping is applied when presenting HDR content (content with HLG or PQ transfer functions)
- * alongside other content, whereby maximum input luminance is mapped to maximum output luminance
- * and intermediate values are interpolated.

+ * 1. Electrical-Optical Transfer Function (EOTF) maps the input RGB signal into the intended
+ * relative display brightness of the scene in nits for each RGB channel
+ * 2. Transformation matrix from linear RGB brightness to linear XYZ, to operate on display
+ * luminance.
+ * 3. Opto-Optical Transfer Function (OOTF) applies a "rendering intent". This can include tone
+ * mapping to display SDR content alongside HDR content, or any number of subjective transformations
+ * 4. Transformation matrix from linear XYZ back to linear RGB brightness.
+ * 5. Opto-Electronic Transfer Function (OETF) maps the display brightness of the scene back to
+ * output RGB colors.
+ *
+ * For further reading, consult the recommendation in ITU-R BT.2390-4:
+ * https://www.itu.int/dms_pub/itu-r/opb/rep/R-REP-BT.2390-4-2018-PDF-E.pdf
+ *
+ * Skia normally attempts to do its own simple tone mapping, i.e., the working color space is
+ * intended to be the output surface. However, Skia does not support complex tone mapping such as
+ * polynomial interpolation. As such, this filter assumes that tone mapping has not yet been applied
+ * to the source colors. so that the tone mapping process is only applied once by this effect. Tone
+ * mapping is applied when presenting HDR content (content with HLG or PQ transfer functions)
+ * alongside other content, whereby maximum input luminance is mapped to maximum output luminance
+ * and intermediate values are interpolated.

+//
+// Drivers must define an appropriate gpu_work_period kernel tracepoint (for
+// example, using the DECLARE_EVENT_CLASS and DEFINE_EVENT macros) such that the
+// arguments/fields match the fields of |GpuWorkPeriodEvent|, excluding the
+// initial "common" field. Drivers must invoke the tracepoint (also referred to
+// as emitting the event) as described below. Note that the description below
+// assumes a single physical GPU and its driver; for devices with multiple GPUs,
+// each GPU and its driver should emit events independently, using a different
+// value for |gpu_id| per GPU.
+//
+// |GpuWorkPeriodEvent| defines a non-overlapping, non-zero period of time from
+// |start_time_ns| (inclusive) until |end_time_ns| (exclusive) for a given
+// |uid|, and includes details of how much work the GPU was performing for |uid|
+// during the period. When GPU work for a given |uid| runs on the GPU, the
+// driver must track one or more periods that cover the time where the work was
+// running, and emit events soon after. The driver should try to emit the event
+// for a period at most 1 second after |end_time_ns|, and must emit the event at
+// most 2 seconds after |end_time_ns|. A period's duration (|end_time_ns| -
+// |start_time_ns|) must be at most 1 second. Periods for different |uids| can
+// overlap, but periods for the same |uid| must not overlap. The driver must
+// emit events for the same |uid| in strictly increasing order of
+// |start_time_ns|, such that it is guaranteed that the tracepoint call for a
+// period for |uid| has returned before the tracepoint call for the next period
+// for |uid| is made. Note that synchronization may be necessary if the driver
+// emits events for the same |uid| from different threads/contexts. Note that
+// |end_time_ns| for a period for a |uid| may equal the |start_time_ns| of the
+// next period for |uid|. The driver should try to avoid emitting a large number
+// of events in a short time period (e.g. 1000 events per second) for a given
+// |uid|.
+//
+// The |total_active_duration_ns| must be set to the approximate total amount of
+// time the GPU spent running work for |uid| within the period, without
+// "double-counting" parallel GPU work on the same GPU for the same |uid|. "GPU
+// work" should correspond to the "GPU slices" shown in the AGI (Android GPU
+// Inspector) tool, and so should include work such as fragment and non-fragment
+// work/shaders running on the shader cores of the GPU. For example, given the
+// following:
+//  - A period has:
+//    - |start_time_ns|: 100,000,000 ns
+//    - |end_time_ns|:   800,000,000 ns
+//  - Some GPU vertex work (A):
+//    - started at:      200,000,000 ns
+//    - ended at:        400,000,000 ns
+//  - Some GPU fragment work (B):
+//    - started at:      300,000,000 ns
+//    - ended at:        500,000,000 ns
+//  - Some GPU fragment work (C):
+//    - started at:      300,000,000 ns
+//    - ended at:        400,000,000 ns
+//  - Some GPU fragment work (D):
+//    - started at:      600,000,000 ns
+//    - ended at:        700,000,000 ns
+//
+// The |total_active_duration_ns| would be 400,000,000 ns, because GPU work for
+// |uid| was executing:
+//  - from 200,000,000 ns to 500,000,000 ns, giving a duration of 300,000,000 ns
+//    (encompassing GPU work A, B, and C)
+//  - from 600,000,000 ns to 700,000,000 ns, giving a duration of 100,000,000 ns
+//    (GPU work D)
+//
+// Thus, the |total_active_duration_ns| is the sum of the (non-overlapping)
+// durations. Drivers may not have efficient access to the exact start and end
+// times of all GPU work, as shown above, but drivers should try to
+// approximate/aggregate the value of |total_active_duration_ns| as accurately
+// as possible within the limitations of the hardware, without double-counting
+// parallel GPU work for the same |uid|. The |total_active_duration_ns| value
+// must be less than or equal to the period duration (|end_time_ns| -
+// |start_time_ns|); if the aggregation approach might violate this requirement
+// then the driver must clamp |total_active_duration_ns| to be at most the
+// period duration.
+//
+// Note that the above description allows for a certain amount of flexibility in
+// how the driver tracks periods and emits the events. We list a few examples of
+// how drivers might implement the above:
+//
+// - 1: The driver could track periods for all |uid| values at fixed intervals
+//   of 1 second. Thus, every period duration would be exactly 1 second, and
+//   periods from different |uid|s that overlap would have the same
+//   |start_time_ns| and |end_time_ns| values.
+//
+// - 2: The driver could track periods with many different durations (up to 1
+//   second), as needed in order to cover the GPU work for each |uid|.
+//   Overlapping periods for different |uid|s may have very different durations,
+//   as well as different |start_time_ns| and |end_time_ns| values.
+//
+// - 3: The driver could track fine-grained periods with different durations
+//   that precisely cover the time where GPU work is running for each |uid|.
+//   Thus, |total_active_duration_ns| would always equal the period duration.
+//   For example, if a game was running at 60 frames per second, the driver
+//   would most likely emit _at least_ 60 events per second (probably more, as
+//   there would likely be multiple "chunks" of GPU work per frame, with gaps
+//   between each chunk). However, the driver may sometimes need to resort to
+//   more coarse-grained periods to avoid emitting thousands of events per
+//   second for a |uid|, where |total_active_duration_ns| would then be less
+//   than the period duration.

 `InputDispatcher` tracks two pieces of state information regarding Pointer Capture:
 
-- `mFocusedWindowRequestedPointerCapture`: Whether or not the focused window has requested Pointer Capture. This is updated whenever the Dispatcher receives requests from `InputManagerService`.
+- `mCurrentPointerCaptureRequest`: The sequence number of the current Pointer Capture request. This request is enabled iff the focused window has requested Pointer Capture. This is updated whenever the Dispatcher receives requests from `InputManagerService`.
 - `mWindowTokenWithPointerCapture`: The Binder token of the `InputWindow` that currently has Pointer Capture. This is only updated during the dispatch cycle. If it is not `nullptr`, it signifies that the window was notified that it has Pointer Capture.

+ * Even though the Pointer 1 up event contains updated Pointer 0 coordinates, there is another MOVE
+ * event generated afterwards that contains the newest movement of pointer 0.
+ * This is important for palm rejection. If there is a subsequent InputListener stage that detects

- * This is the frameNumber used for deferred transaction signalling. We need to use this because

- *     DeferTransactionUntil -> frameNumber = 2
- *     Random other stuff

- * Prior to doTransaction SurfaceFlinger will call notifyAvailableFrames, but because we

- * is not ready. So we will return false from applyPendingState and not swap
- * current state to drawing state. But because we don't swap current state
- * to drawing state the number will never update and we will be stuck. This way

+### LayerTraceGenerator ###
+
+Generates layer traces from transaction traces. The tool is a custom
+surface flinger build that mocks out everything else apart from the
+front end logic. Transaction traces are written when the transaction
+is applied, along wth a timestamp and vsync id. The transactions
+are parsed from proto and applied to recreate the layer state. The
+result is then written as a layer trace.
+
+Usage:
+1. build and push to device
+2. run ./layertracegenerator [transaction-trace-path] [output-layers-trace-path]

+### TransactionTrace Testsuite ###
+
+Hassle free way to test and validate whether a sequence of
+transactions will produce the expected front end state(s). Test
+runs through all testdata/transactions_trace_*.winscope files,
+generates layer states and checks if the states match the
+corresponding layer trace in testdata.
+
+
+#### Run Test ####
+`atest transactiontrace_testsuite`
+
+
+#### Workflow ####
+Add transaction traces that resulted in front end bugs along
+with the layer trace after fixing the issue. The layer trace
+can be generated by using the layertracegenerator tool. The
+main goal of this test suite is to add regression tests with
+minimal effort.

 ## Code Generation
 
-We generate several parts of the loader and tools driectly from the Vulkan Registry (external/vulkan-headers/registry/vk.xml). Code generation must be done manually because the generator is not part of the platform toolchain (yet?). Files named `foo_gen.*` are generated by the code generator.
