991288 – VM has quit abnormally while iofuzz testing

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description CongLi 2013-08-02 05:23:00 UTC

Description of problem:
VM has quit abnormally while iofuzz testing

Version-Release number of selected component (if applicable):

2.
    KVM iofuzz test:
    1) Log into a guest
    2) Enumerate all IO port ranges through /proc/ioports
    3) On each port of the range:
        * Read it
        * Write 0 to it
        * Write a random value to a random port on a random order

3.

Actual results:
VM has quit abnormally during write

Expected results:
VM works well

Met this bug again on the following version:

kernel-3.10.0-114.el7.x86_64
qemu-kvm-rhev-1.5.3-57.el7ev.x86_64

Here are the qemu output:

As this bug dup to bz969945, and bz969945 has been 'VERIFIED', maybe they are different bugs.
So could we re-open it?

This is separate from the others; from comment #5

hw/scsi/virtio-scsi.c

static void virtio_scsi_set_config(VirtIODevice *vdev,
                                   const uint8_t *config)
{
    VirtIOSCSIConfig *scsiconf = (VirtIOSCSIConfig *)config;
    VirtIOSCSICommon *vs = VIRTIO_SCSI_COMMON(vdev);

    if ((uint32_t) ldl_raw(&scsiconf->sense_size) >= 65536 ||
        (uint32_t) ldl_raw(&scsiconf->cdb_size) >= 256) {
        error_report("bad data written to virtio-scsi configuration space");
        exit(1);
    }

    vs->sense_size = ldl_raw(&scsiconf->sense_size);
    vs->cdb_size = ldl_raw(&scsiconf->cdb_size);
}

Are you able to reproduce this on every run ?

According to the recent tests, I could say yes, can hit this issue on every run.
