Subject: [PULL 2/7] fuzz: refine the ide/ahci fuzzer configs
Date: Wed, 20 Jan 2021 12:44:51 -0500	[thread overview]
Message-ID: <20210120174456.275312-3-alxndr@bu.edu> (raw)
In-Reply-To: <20210120174456.275312-1-alxndr@bu.edu>

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.
