Kernel Fuzzing: Understanding Syzkaller and Coverage Improvements

a project by jpovoas

Description

I want to set up a local kernel fuzzing environment using Syzkaller [0] to better understand its architecture. My focus will be on input mutation logic, subsystem modeling, and how coverage descriptions are currently structured. I'm particularly interested in rapidly evolving subsystems like io_uring and BPF to see where fuzzing descriptions might be incomplete or outdated. I'd like to write at least one custom syzlang definition to better understand the process and identify potential coverage improvements.
