https://bugzilla.kernel.org/show_bug.cgi?id=200109 --- Comment #3 from icytxw (icytxw@xxxxxxxxx) --- Thanks for your advise, I also know that syzkaller's log file is not so easy to understand. And because the possibility of some bug being triggered is very small, it is not so easy to generate a .c file. In the next time, I will work on how to reproduce possible bugs just like Wen Xu’s fuzzing system.

Please note that Syzkaller is really terrible at creating an actionable bug report. But at least the mainline Syzkaller creates a repro.c file which a developer can run --- instead of having to paw through a one megabyte log file which apparently has a huge number of unrelated test programs. Syzkaller programs are also not in as stable language, so unless you know exactly what version of syzkaller was used to create a syzkaller repro, it's mostly useless. Indeed, Dmitry has essentially advised me to ignore the syzkaller repro, since otherwise you have to check out the precise version of syzkaller used to create the repro, and use it to run the syzkaller repro. I personally think that's a terrible design, but at least there is the alternative of using the repro.c file. I'd strongly encourage that you work on enhancing Syzkaller so it can generate a sample image file combined with a poc.c file, the way Wen Xu's fuzzing system works. It results in a much more developer-friendly report that is much easier for me to act upon --- with the result that his work has far more impact.
