GSoC'25: Replace QEMUAFL with LibAFL_QEMU

[domenukk]

This project will be to replace qemuafl https://github.com/AFLplusplus/qemuafl with LibAFL_QEMU.
The end goal is to be able to run AFL++ as frontend for LibAFL_QEMU.

For this, we will need to finish the following PR:
#1983

Mainly we
a) Need to speak the AFL++ forkserver protocol (see PR)
b) Add TCG caching to the LibAFL_QEMU forkserver
c) Use LibAFL_QEMU snapshots where possible
d) Add as many env variable features as possible

This is a proposal for a GSoC project.

Hey @domenukk,

I’m Paniv Kapoor, and I came across the GSoC project proposal to replace qemuafl with LibAFL_QEMU. It looks really interesting, and I’d love to contribute while learning more about the AFL++ forkserver protocol, TCG caching, and snapshot usage in LibAFL_QEMU.

Is there any qualification task for this project? Also, if you have any recommended resources for learning Rust (assuming LibAFL_QEMU is in Rust) and understanding the internals of AFL++/QEMU, that would be super helpful!

Looking forward to your response. Thanks!

Best,
Paniv Kapoor
