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 yisun 2021-10-14 13:53:30 UTC 
versions:
libvirt-7.8.0-1.el9.x86_64

how reproducible:
100%

steps:
1. prepare a host with hba card connecting to san storage, here we have scsi12 as the connected storage
[root@dell-per730-58 ~]# virsh nodedev-dumpxml scsi_host12
<device>
  <name>scsi_host12</name>
  <path>/sys/devices/pci0000:00/0000:00:03.2/0000:06:00.1/host12</path>
  <parent>pci_0000_06_00_1</parent>
  <capability type='scsi_host'>
    <host>12</host>
    <unique_id>12</unique_id>
    <capability type='fc_host'>
      <wwnn>2000f4e9d4eb02c9</wwnn>
      <wwpn>2001f4e9d4eb02c9</wwpn>
      <fabric_wwn>2001547feebe79c1</fabric_wwn>
    </capability>
    <capability type='vport_ops'>
      <max_vports>254</max_vports>
      <vports>0</vports>
    </capability>
  </capability>
</device>

2. prepare a device xml to generate a vhba device
[root@dell-per730-58 ~]# cat vhba.xml 
<device><parent>scsi_host12</parent><capability type='scsi_host'><capability type='fc_host'></capability></capability></device>

3. try to create the vhba 
[root@dell-per730-58 ~]# virsh nodedev-create vhba.xml 
error: Failed to create node device from vhba.xml
error: End of file while reading data: Input/output error

4. crash happens to /usr/sbin/virtnodedevd daemon
gdb backtrace info as follow for the segmentation fault:

...
(gdb) c
Continuing.

Thread 3 "rpc-worker" received signal SIGSEGV, Segmentation fault.

Comment 2 Peter Krempa 2021-10-18 07:58:09 UTC 
The issue is that the new post-parse callbacks for node devices are called even when the XML parser fails. This is not related to split vs monolithic daemon though.

Comment 4 Peter Krempa 2021-10-18 15:43:00 UTC 
commit 8eb08e0fc5fe42efd2b0a4226f2b71f183ba193b
Author: Peter Krempa <pkrempa>
Date:   Mon Oct 18 09:54:08 2021 +0200

    virNodeDeviceDefParse: Don't call post-parse callbacks with NULL def
    
    When parsing of the node device XML fails we'd still call the post-parse
    and validation callbacks which makes no sense. Additionally the
    callbacks were expecting a non-NULL pointer which leads to a crash.
