Main differences with previous setup are: - No manifest creation - gst-indent is executed only when the bot is assigned (instead of the manifest task) - Cerbero jobs are triggered in the cerbero repo - Remove cerbero and android related files as they now are in cerbero itself. - Update `container.ps1` to the new file layout Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/891>

Fuzzing GStreamer
|
|
=================
|
|
|
|
This directory contains the various fuzzing targets and helper
|
|
scripts.
|
|
|
|
* Fuzzing targets
|
|
|
|
Fuzzing targets as small applications where we can test a specific
|
|
element or API. The goal is to have them be as small/targetted as
|
|
possible.
|
|
|
|
ex: appsrc ! <some_element> ! fakesink num-buffers=<small>
|
|
|
|
Not all components can be tested directly and therefore will be
|
|
indirectly tested via other targets (ex: libgstaudio will be tested
|
|
by targets/elements requiring it)
|
|
|
|
Anything that can process externally-provided data should be
|
|
covered, but there are cases where it might not make sense to use a
|
|
fuzzer (such as most elements processing raw audio/video).
|
|
|
|
* build-oss-fuzz.sh
|
|
|
|
This is the script executed by the oss-fuzz project.
|
|
|
|
It builds glib, GStreamer, plugins and the fuzzing targets.
|
|
|
|
* *.c
|
|
|
|
The fuzzing targets where the data to test will be provided to a
|
|
function whose signature follows the LibFuzzer signature:
|
|
https://llvm.org/docs/LibFuzzer.html
|
|
|
|
* TODO
|
|
|
|
* Add a standalone build script
|
|
|
|
We need to be able to build and test the fuzzing targets outside
|
|
of the oss-fuzz infrastructure, and do that in our continous
|
|
integration system.
|
|
|
|
We need:
|
|
|
|
* A dummy fuzzing engine (given a directory, it opens all files and
|
|
calls the fuzzing targets with the content of those files.
|
|
* A script to be able to build those targets with that dummy engine
|
|
* A corpus of files to test those targets with.
|
|
|
|
* Build targets with dummy engine and run with existing tests.
|
|
|
|
* Create pull-based variants
|
|
|
|
Currently the existing targets are push-based only. Where
|
|
applicable we should make pull-based variants to test the other
|
|
code paths.
|
|
|
|
* Add more targets
