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.Signed-off-by: Alexander Bulekov <alx...@bu.edu> --- v2: Fix ide-hd -> ide-cd in the ahci-atapi config tests/qtest/fuzz/generic_fuzz_configs.h | 20 +++++++++++++++++++- 1 file changed, 19 insertions(+), 1 deletion(-) diff --git a/tests/qtest/fuzz/generic_fuzz_configs.h b/tests/qtest/fuzz/generic_fuzz_configs.h index 7fed035345..aa4c03f1ae 100644 --- a/tests/qtest/fuzz/generic_fuzz_configs.h +++ b/tests/qtest/fuzz/generic_fuzz_configs.h @@ -85,10 +85,28 @@ const generic_fuzz_config predefined_configs[] = { .objects = "intel-hda", },{ .name = "ide-hd", + .args = "-machine pc -nodefaults " + "-drive file=null-co://,if=none,format=raw,id=disk0 " + "-device ide-hd,drive=disk0", + .objects = "*ide*", + },{ + .name = "ide-atapi", + .args = "-machine pc -nodefaults " + "-drive file=null-co://,if=none,format=raw,id=disk0 " + "-device ide-cd,drive=disk0", + .objects = "*ide*", + },{ + .name = "ahci-hd", .args = "-machine q35 -nodefaults " "-drive file=null-co://,if=none,format=raw,id=disk0 " "-device ide-hd,drive=disk0", - .objects = "ahci*", + .objects = "*ahci*", + },{ + .name = "ahci-atapi", + .args = "-machine q35 -nodefaults " + "-drive file=null-co://,if=none,format=raw,id=disk0 " + "-device ide-cd,drive=disk0", + .objects = "*ahci*", },{ .name = "floppy", .args = "-machine pc -nodefaults -device floppy,id=floppy0 "
