-# Bug fixing guidance
-{: .no_toc}
-
-This page provides brief guidance on how to prioritise and fix bugs reported by
-OSS-Fuzz.
-
-- TOC
-{:toc}
-
-## Threat modelling
-In general the severity of an issue reported by OSS-Fuzz must be determined
-relative to the threat model of the project under analysis. Therefore, although
-the fuzzers OSS-Fuzz makes an effort into determining the severity of the bug
-the true severity of the bug depends on the threat model of the project.
-
-## Bug prioritisation
-
-### Security issues
-These are the top priority of solving. A label is attached to these on
-the OSS-Fuzz testcase page and you can also search up all of these on monorail
-using the search pattern `-Bug=security`.
-
-Issues of this kind include issues reported by Address Sanitizer, e.g.
-heap-based buffer overflows, stack-based buffer overflows and use-after-frees.
-
-### Functional issues and memory leaks
-These are issues that in general can tamper with the functionality of the
-application. The bugs that have highest priority in this case are those that
-can be easily triggered by an untrusted user of the project.
-
-### Timeouts and out-of-memory
-These are in general the least prioritised issues to solve.
-
-### Bug prioritisation of non C/C++ projects
-Currently there is no prioritisation of bugs in non C/C++ projects. As such, in
-this scenario it is crucial you do the analysis yourself relative to the threat
-model of your project.
-
-## Non-reproducible bugs
-OSS-Fuzz will report some bugs that are labeled `Reliably reproduces: NO` and
-these can be tricky to deal with. A non-reproducible bug is an issue that
-OSS-Fuzz did indeed discover, however, OSS-Fuzz is unable to reproduce the bug
-with `python infra/helper.py reproduce`. In general, our suggestion is to do
-analysis of the bug and determine whether there in fact is an issue.
-
-The non-reproducible bugs can be of varying nature. Some of these bugs will be
-due to some internal state of the target application being manipulated over the
-cause of several executions of the fuzzer function. This could be several
-hundreds or even thousands of executions and the bug may not be reproducible by
-a single fuzzer test-case, however, there is indeed a bug in the application.
-There are other reasons why bugs may be non-reproducible and in general any
-non-determinism introduced into the application can have an effect on this.
-
-In the case of non-reproducible bugs our advice is to put effort into analysing
-the potential bug and also assess whether this is due to some internal state
-that persists between each fuzz run. If that is indeed the case then we also
-suggest investigating whether the fuzzer can be written such that the internal
-state in the code will be reset between each fuzz run.
-
-## Should all reported issues be solved?
-It is reported by some project maintainers that fixing timeout issues reported
-by OSS-Fuzz can increase the complexity of the project’s source code. The
-result of this is that maintainers put effort into solving a timeout issue and
-the fix results in additional complexity of the project. The question is
-whether in a scenario like this if the overall result actually improves the
-state of the application.
-
-In order to answer this question we must assess the issue relative to the
-threat model. Following the timeout anecdote then some timing issues can have
-severe security implications. For example, if the timeout issue can cause
-manipulation of control-flow then the timing issue may be of high security
-severity. As such, it is difficult to say in the general case whether or not
-some bugs should not be solved, as it should be analysed and determined on a
-project-by-project basis.
-
-In the event that a bug is reported by OSS-Fuzz that is not relevant to
-security or reliability of the application then there may still be a point to
-fixing the bug. For example, if the issue is often run into by the fuzzer then
-the fuzzer may have difficulty exploring further code in the target, and thus
-fixing the bug will allow the fuzzer to explore further code. In this case some
-suggested examples of resolving the issue could be:
-* Perform a hot-patch that is only applied during fuzzer executions and does
-not overcomplicate the project’s code.
-* Patch the code of the fuzzer to avoid the timeout. For example, some fuzzers
-restrict the size of the input to avoid certain deep recursions or
-time-intensive loops.
-* Patch the code in the target despite complicating things.

-
-## Prerequisites
-ClusterFuzzLite supports statically linked
-[libFuzzer targets]({{ site.baseurl }}/reference/glossary/#fuzz-target) on
-Linux.
-
-We re-use the [OSS-Fuzz](https://github.com/google/oss-fuzz) toolchain to make
-building easier. If you are familiar with this, most of the concepts here are
-exactly the same, with one key difference. Rather than checking out the source
-code in the [`Dockerfile`](#dockerfile) using `git clone`, the `Dockerfile`
-copies in the source code directly during `docker build`.
-
-Before you can start setting up your new project for fuzzing, you must do the following:
-- [Integrate]({{ site.baseurl }}/advanced-topics/ideal-integration/) one or more [fuzz targets]({{ site.baseurl }}/reference/glossary/#fuzz-target)
-  with the project you want to fuzz. For examples, see TODO.
-- [Install Docker](https://docs.docker.com/engine/installation)
-  [Why Docker?]({{ site.baseurl }}/faq/#why-do-you-use-docker)
-
-  If you want to run `docker` without `sudo`, you can
-  [create a docker group](https://docs.docker.com/engine/installation/linux/ubuntulinux/#/create-a-docker-group).
-
-  **Note:** Docker images can consume significant disk space. Run
-  [docker-cleanup](https://gist.github.com/mikea/d23a839cba68778d94e0302e8a2c200f)
-  periodically to garbage-collect unused images.
-
-- Clone the OSS-Fuzz repo: `git clone https://github.com/google/oss-fuzz.git`
-
-## Generating an empty build integration
-
-Build integrations consist of three configuration files:
-* [./clusterfuzzlite/project.yaml](#projectyaml) - provides metadata about the project.
-* [./clusterfuzzlite/Dockerfile](#dockerfile) - defines the container environment with information
-on dependencies needed to build the project and its [fuzz targets]({{ site.baseurl }}/reference/glossary/#fuzz-target).
-* [./clusterfuzzlite/build.sh](#buildsh) - defines the build script that executes inside the Docker container and
-generates the project build.
-
-These must live in the `.clusterfuzzlite` directory in the root of your
-project's source code checkout.
-
-You can generate empty versions of these files with the following command:
-
-```bash
-$ cd /path/to/oss-fuzz
-$ export PATH_TO_PROJECT=<path_to_your_project>
-$ python infra/helper.py generate $PATH_TO_PROJECT --external
-```
-
-Once the configuration files are generated, you should modify them to fit your
-project.
-
-## project.yaml {#projectyaml}
-
-This configuration file stores project metadata. The following attributes are
-supported:
-
-- [language](#language)
-
-### language
-
-Programming language the project is written in. Values you can specify include:
-
-* `c`
-* `c++`
-* [`go`]({{ site.baseurl }}//getting-started/new-project-guide/go-lang/)
-* [`rust`]({{ site.baseurl }}//getting-started/new-project-guide/rust-lang/)
-* [`python`]({{ site.baseurl }}//getting-started/new-project-guide/python-lang/)
-* [`jvm` (Java, Kotlin, Scala and other JVM-based languages)]({{ site.baseurl }}//getting-started/new-project-guide/jvm-lang/)
-
-## Dockerfile {#dockerfile}
-
-This integration file defines the Docker image for your project.
-Your [build.sh](#buildsh) script will be executed in inside the container you
-define.
-For most projects, the image is simple:
-```docker
-FROM gcr.io/oss-fuzz-base/base-builder          # base image with clang toolchain
-RUN apt-get update && apt-get install -y ...    # install required packages to build your project
-COPY . $SRC/<project_name>                      # checkout all sources needed to build your project
-WORKDIR $SRC/<project_name>                     # current directory for the build script
-COPY ./clusterfuzzlite/build.sh fuzzer.cc $SRC/ # copy build script into src dir
-```
-TODO: Provide examples.
-
-## build.sh {#buildsh}
-
-This file defines how to build binaries for [fuzz targets]({{ site.baseurl }}/reference/glossary/#fuzz-target) in your project.
-The script is executed within the image built from your [Dockerfile](#Dockerfile).
-
-In general, this script should do the following:
-
-- Build the project using your build system with OSS-Fuzz's compiler.
-- Provide OSS-Fuzz's compiler flags (defined as [environment variables](#Requirements)) to the build system.
-- Build your [fuzz targets]({{ site.baseurl }}/reference/glossary/#fuzz-target)
-  and link your project's build with `$LIB_FUZZING_ENGINE` (libFuzzer).
-
-Resulting binaries should be placed in `$OUT`.
-
-Here's an example from Expat
-([source](https://github.com/google/oss-fuzz/blob/master/projects/expat/build.sh)):
-
-```bash
-#!/bin/bash -eu
-
-./buildconf.sh
-# configure scripts usually use correct environment variables.
-./configure
-
-make clean
-make -j$(nproc) all
-
-$CXX $CXXFLAGS -std=c++11 -Ilib/ \
-    $SRC/parse_fuzzer.cc -o $OUT/parse_fuzzer \
-    $LIB_FUZZING_ENGINE .libs/libexpat.a
-
-cp $SRC/*.dict $SRC/*.options $OUT/
-```
-
-If your project is written in Go, check out the [Integrating a Go project]({{ site.baseurl }}//getting-started/new-project-guide/go-lang/) page.
-
-**Note:**
-1. Make sure that the binary names for your [fuzz targets]({{ site.baseurl }}/reference/glossary/#fuzz-target) contain only
-alphanumeric characters, underscore(_) or dash(-). Otherwise, they won't run.
-1. Don't remove source code files. They are needed for code coverage.
-
-
-### Temporarily disabling code instrumentation during builds
-
-In some cases, it's not necessary to instrument every 3rd party library or tool that supports the build target. Use the following snippet to build tools or libraries without instrumentation:
-
-```
-CFLAGS_SAVE="$CFLAGS"
-CXXFLAGS_SAVE="$CXXFLAGS"
-unset CFLAGS
-unset CXXFLAGS
-export AFL_NOOPT=1
-
-#
-# build commands here that should not result in instrumented code.
-#
-
-export CFLAGS="${CFLAGS_SAVE}"
-export CXXFLAGS="${CXXFLAGS_SAVE}"
-unset AFL_NOOPT
-```
-TODO: Figure out if we should include this AFL code.
-
-### build.sh script environment
-
-When your build.sh script is executed, the following locations are available within the image:
-
-| Location| Env Variable | Description |
-|---------| ------------ | ----------  |
-| `/out/` | `$OUT`         | Directory to store build artifacts (fuzz targets, dictionaries, options files, seed corpus archives). |
-| `/src/` | `$SRC`         | Directory to checkout source files. |
-| `/work/`| `$WORK`        | Directory to store intermediate files. |
-
-Although the files layout is fixed within a container, environment variables are
-provided so you can write retargetable scripts.
-
-In case your fuzz target uses the [FuzzedDataProvider] class, make sure it is
-included via `#include <fuzzer/FuzzedDataProvider.h>` directive.
-
-[FuzzedDataProvider]: https://github.com/google/fuzzing/blob/master/docs/split-inputs.md#fuzzed-data-provider
-
-### build.sh requirements {#Requirements}
-
-Only binaries without an extension are accepted as targets. Extensions are reserved for other artifacts, like .dict.
-
-You *must* use the special compiler flags needed to build your project and fuzz targets.
-These flags are provided in the following environment variables:
-
-| Env Variable           | Description
-| -------------          | --------
-| `$CC`, `$CXX`, `$CCC`  | The C and C++ compiler binaries.
-| `$CFLAGS`, `$CXXFLAGS` | C and C++ compiler flags.
-| `$LIB_FUZZING_ENGINE`  | C++ compiler argument to link fuzz target against the prebuilt engine library (e.g. libFuzzer).
-
-You *must* use `$CXX` as a linker, even if your project is written in pure C.
-
-Most well-crafted build scripts will automatically use these variables. If not,
-pass them manually to the build tool.
-
-See the [Provided Environment Variables](https://github.com/google/oss-fuzz/blob/master/infra/base-images/base-builder/README.md#provided-environment-variables) section in
-`base-builder` image documentation for more details.
-
-## Fuzzer execution environment
-
-For more on the environment that
-your [fuzz targets]({{ site.baseurl }}/reference/glossary/#fuzz-target) run in, and the assumptions you can make, see the [fuzzer environment]({{ site.baseurl }}/further-reading/fuzzer-environment/) page.
-
-## Testing locally
-
-You can build your docker image and fuzz targets locally, so you can test them
-before running ClusterFuzzLite.
-1. Run the same helper script you used to create your directory structure, this time using it to build your docker image and [fuzz targets]({{ site.baseurl }}/reference/glossary/#fuzz-target):
-
-    ```bash
-    $ cd /path/to/oss-fuzz
-    $ python infra/helper.py build_image $PATH_TO_PROJECT --external
-    $ python infra/helper.py build_fuzzers $PATH_TO_PROJECT --sanitizer <address/undefined/coverage> --external
-    ```
-
-    The built binaries appear in the `/path/to/oss-fuzz/build/out/$PROJECT_NAME`
-    directory on your machine (and `$OUT` in the container). Note that
-    `$PROJECT_NAME` is the name of the directory of your project (e.g. if
-    `$PATH_TO_PROJECT` is `/path/to/systemd`, `$PROJECT_NAME` is systemd.
-
-    **Note:** You *must* run your fuzz target binaries inside the base-runner docker
-    container to make sure that they work properly.
-
-2. Find failures to fix by running the `check_build` command:
-
-    ```bash
-    $ python infra/helper.py check_build $PATH_TO_PROJECT --external
-    ```
-
-3. If you want to test changes against a particular fuzz target, run the following command:
-
-    ```bash
-    $ python infra/helper.py run_fuzzer --external --corpus-dir=<path-to-temp-corpus-dir> $PATH_TO_PROJECT <fuzz_target>
-    ```
-
-4. We recommend taking a look at your code coverage as a test to ensure that
-your fuzz targets get to the code you expect. This would use the corpus
-generated from the previous `run_fuzzer` step in your local corpus directory.
-
-    ```bash
-    $ python infra/helper.py build_fuzzers --sanitizer coverage $PATH_TO_PROJECT
-    $ python infra/helper.py coverage $PATH_TO_PROJECT --fuzz-target=<fuzz_target> --corpus-dir=<path-to-temp-corpus-dir> --external
-    ```
-
-You may need to run `python infra/helper.py pull_images` to use the latest
-coverage tools. Please refer to
-[code coverage]({{ site.baseurl }}/advanced-topics/code-coverage/) for detailed
-information on code coverage generation.
-
-**Note:** Currently, ClusterFuzzLite only supports AddressSanitizer (address)
-and UndefinedBehaviorSanitizer (undefined) configurations.
-<b>Make sure to test each
-of the supported build configurations with the above commands (build_fuzzers -> run_fuzzer -> coverage).</b>
-
-If everything works locally, it should also work on ClusterFuzzLite. If you
-check in your files and experience failures, review your [dependencies]({{site.baseurl }}/further-reading/fuzzer-environment/#dependencies).
-
-## Debugging Problems
-
-If you run into problems, the [Debugging page]({{ site.baseurl }}/advanced-topics/debugging/) lists ways to debug your build scripts and
-[fuzz targets]({{ site.baseurl }}/reference/glossary/#fuzz-target).
-
-## Efficient fuzzing
-
-To improve your fuzz target ability to find bugs faster, please read [this section](
-{{ site.baseurl }}/getting-started/new-project-guide/#efficient-fuzzing).
-
-TODO(metzman): We probably want a TOC for lang-specific guides (which we still need to add).

-# ClusterFuzzLite
-ClusterFuzzLite is a lightweight, easy-to-use, fuzzing infrastructure that is
-based off [ClusterFuzz]. ClusterFuzzLite is designed to run on [continuous integration] (CI)
-systems, which means it is easy to set up and provides a familiar interface for
-users.
-Currently CIFuzz fully supports [GitHub Actions]. However ClusterFuzzLite is
-designed so that supporting new CI systems is trivial and core features can be
-used on any CI system without any additional effort.
-
-See [Overview] for a more detailed description of how ClusterFuzzLite works and

-# Overview
-
-ClusterFuzzLite makes fuzzing more valuable by:
-* Fuzzing continuously.
-* Catching bugs before they land in your codebase by fuzzing pull
-  requests/commits.
-* Providing coverage reports on which code is fuzzed.
-* Managing your corpus, pruning it daily or a specified-interval.
-
-ClusterFuzzLite supports [libFuzzer], [AddressSanitizer], and
-[UndefinedBehavior].
-ClusterFuzzLite is modular, so you can decide which features you want to use.
-Using ClusterFuzzLite entails two major steps:
-1. [Integrating with ClusterFuzzLite's build system] so ClusterFuzzLite can
-   build your project's fuzzers.
-2. [Running ClusterFuzzLite].

-Once your project's fuzzers can be built and run by the helper script, it is
-ready to be fuzzed by ClusterFuzzLite.
-The exact method for doing this will depend on the how you are running
-ClusterFuzzLite. For guides on how to run ClusterFuzzLite in your particular
-environment (e.g. GitHub Actions) see the subguides.
-The rest of this page will explain concepts configuration options and that are
-agnostic to how ClusterFuzzLite is being run.
-
-## ClusterFuzzLite Tasks
-
-ClusterFuzzLite has the concept of tasks which instruct ClusterFuzzLite what to
-do when running.
-
-### Code Review Fuzzing
-
-TODO(metzman): Work on a generic name for CIFuzz/PR fuzzing.
-
-One of the core ways for ClusterFuzzLite to be used is for fuzzing code that is
-in review that was just commited.
-This use-case is important because it allows ClusterFuzzLite to find bugs before
-they are commited into your code and while they are easiest to fix.
-To use Code Review Fuzzing, set the configuration option `clusterfuzzlite-task`
-to `code-review`.
-If you are familiar with OSS-Fuzz's CIFuzz, this task is similar to CIFuzz.
-Running other ClusterFuzzLite tasks enhances ClusterFuzzLite's ability to do
-Code Review Fuzzing.
-
-If [Batch Fuzzing] is enabled, Code Review Fuzzing will report only newly
-introduced bugs and use the corpus developed during batch fuzzing.
-If [Code Coverage Reporting] is enabled, Code Review Fuzzing will try to only
-run the fuzzers affected by the code change.
-
-### Batch Fuzzing
-
-ClusterFuzzLite can also run in a batch fuzzing mode where all fuzzers are run
-for a long amount of time. Unlike Code Review Fuzzing, this task is not meant to
-be interactive, it is meant to be long-lasting and generally is more similar to
-fuzzing in ClusterFuzz than Code Review Fuzzing. Batch Fuzzing allows
-ClusterFuzzLite to build up a corpus for each of your fuzz targets. This corpus
-will be used in Code Coverage Reporting as well as Code Review Fuzzing.
-
-### Corpus Prune
-
-If multiple Batch Fuzzing tasks are run concurrently then we strongly recommend
-running a pruning task as well. This task is run according to some set schedule
-(once a day is probably sufficient) to prune the corpus of redundant testcases,
-which can happen if multiple Batch Fuzzing jobs are done concurrently.
-
-### Code Coverage Report
-
-The last task ClusterFuzzLite offers is Code Coverage Reports. This task will
-run your fuzzers on the corpus developed during Batch Fuzzing and will generate
-an HTML report that shows you which part of your code is covered by batch
-fuzzing.
-
-## Configuration Options
-
-Below are some configuration options that you can set when running
-ClusterFuzzLite.
-We will explain how to set these in each of the subguides.
-
-`language`: (optional) The language your target program is written in. Defaults
-to `c++`. This should be the same as the value you set in `project.yaml`. See
-[this explanation]({{ site.baseurl }}//getting-started/new-project-guide/#language)
-for more details.
-
-`fuzz-time`: Determines how long ClusterFuzzLite spends fuzzing your project in
-seconds. The default is 600 seconds.
-
-`sanitizer`: Determines a sanitizer to build and run fuzz targets with. The
-choices are `'address'`, and `'undefined'`. The default is `'address'`.
-
-`task`: The task for ClusterFuzzLite to execute. `code-review`
-by default. See [ClusterFuzzLite Tasks] for more details on how to run different
-tasks.
-TODO(metzman): change run_fuzzers_mode to this.
-
-`dry-run`: Determines if ClusterFuzzLite surfaces bugs/crashes. The default
-value is `false`. When set to `true`, ClusterFuzzLite will never report a
-failure even if it finds a crash in your project. This requires the user to
-manually check the logs for detected bugs.
-
-TODO(metzman): We probably want a TOC on this page for subguides.

-## Writing fuzzers using a test-style strategy
-
-In Rust you will often have tests written in a way so they are only 
-compiled into the final binary when build in test-mode. This is, achieved by
-wrapping your test code in `cfg(test)`, e.g.
-```rust
-#[cfg(test)]
-mod tests {
-    use super::*;
-    
-    ...
-```
-
-Cargo-fuzz automatically enables the `fuzzing` feature, which means you can
-follow a similar strategy to writing fuzzers as you do when writing tests.
-Specifically, you can create modules wrapped in the `fuzzing` feature:
-```rust
-#[cfg(fuzzing)]
-pub mod fuzz_logic {
-    use super::*;
-
-    ...
-```
-and then call the logic within `fuzz_logic` from your fuzzer. 
-
-Furthermore, within your `.toml` files, you can then specify fuzzing-specific
-depedencies by wrapping them as follows:
-```
-[target.'cfg(fuzzing)'.dependencies]
-```
-similar to how you wrap test-dependencies as follows:
-```
-[dev-dependencies]
-```
-
-Finally, you can also combine the testing logic you have and the fuzz logic. This
-can be achieved simply by using 
-```rust
-#[cfg(any(test, fuzzing))]
-```
-
-A project that follows this structure is Linkerd2-proxy and the project files can be
-seen [here](https://github.com/google/oss-fuzz/tree/master/projects/linkerd2-proxy).

-The process of integrating a project written in Swift with OSS-Fuzz is very similar
-to the general
-[Setting up a new project]({{ site.baseurl }}/getting-started/new-project-guide/)
-process. The key specifics of integrating a Swift project are outlined below.
-
-## Project files
-
-First, you need to write a Swift fuzz target that accepts a stream of bytes and
-calls the program API with that. This fuzz target should reside in your project
-repository.
-
-The structure of the project directory in OSS-Fuzz repository doesn't differ for
-projects written in Swift. The project files have the following Swift specific
-aspects.
-
-### project.yaml
-
-The `language` attribute must be specified.
-
-```yaml
-language: swift
-```
-
-The only supported fuzzing engine is `libfuzzer`
-
-The supported sanitizers are and `address`, `thread`
-

-
-```yaml
-fuzzing_engines:
-  - libfuzzer
-sanitizers:
-  - address
-  - thread
-```
-
-### Dockerfile
-
-The Dockerfile should start by `FROM gcr.io/oss-fuzz-base/base-builder-swift`
-instead of using the simple base-builder
-
-### build.sh
-
-A `precompile_swift` generates an environment variable `SWIFTFLAGS`
-This can then be used in the building command such as `swift build -c release $SWIFTFLAGS`
-
-
-A usage example from swift-protobuf project is
-
-```sh
-. precompile_swift
-# build project
-cd FuzzTesting
-swift build -c debug $SWIFTFLAGS
-
-(
-cd .build/debug/
-find . -maxdepth 1 -type f -name "*Fuzzer" -executable | while read i; do cp $i $OUT/"$i"-debug; done
