Hi,
thank you for releasing this project. I'm trying to run it on a 5.4 kernel according to the README. I have ported the kernel patches and the kernel boots and seems to work just fine. I'm using the stretch.img you've made available. However, when I try to fuzz AFL quits right away complaining that the seeds crash the target. I tested manually and I get the following trace with all seeds:

I guess I could try with KASAN disabled but any idea what might be wrong here?

@tklengyel Do you mean that the seed file seeds/usb_sb7VwXl is causing a crash in the version of kernel you are testing?
To make sure that it is not caused by the patches, can you try building a clean version of kernel and test it with the QEMU with a usb-fuzz device?

Sure, but what do you mean by clean version of the kernel? Without KASAN? Without the patches, sure.
