From d54d9b1d124bcea44293e25f3a45c593d798d2a8 Mon Sep 17 00:00:00 2001 From: Alexander Bulekov Date: Wed, 20 Jan 2021 10:22:11 -0500 Subject: fuzz: refine the ide/ahci fuzzer configs Disks work differently depending on the x86 machine type (SATA vs PATA). Additionally, we should fuzz the atapi code paths, which might contain vulnerabilities such as CVE-2020-29443. This patch adds hard-disk and cdrom generic-fuzzer configs for both the pc (PATA) and q35 (SATA) machine types.
