Introduced by commit 244ce462e29, which refactored the
helper for wwn
reading, however, it forgot to change the old "strndup"
and "sizeof(buf)",
"sizeof(buf)" operates on the fixed length array ("buf")
in the old code,
but now "buf" is a pointer.
Before the fix:
% virsh nodedev-dumpxml scsi_host5
<device>
<name>scsi_host5</name>
<parent>pci_0000_04_00_1</parent>
<capability type='scsi_host'>
<host>5</host>
<capability type='fc_host'>
<wwnn>2001001b</wwnn>
<wwpn>2101001b</wwpn>
<fabric_wwn>2001000d</fabric_wwn>
</capability>
</capability>
</device>
With the fix:
% virsh nodedev-dumpxml scsi_host5
<device>
<name>scsi_host5</name>
<parent>pci_0000_04_00_1</parent>
<capability type='scsi_host'>

<capability type='fc_host'>
<wwnn>0x2001001b32a9da4e</wwnn>

<fabric_wwn>0x2001000dec9877c1</fabric_wwn>
</capability>
</capability>

ACK for technically right; however, since this problem is in
1.0.4 is
there an "effect" where there is a written buffer that has the
shorter
(and wrong) wwnn/wwpn that could cause "issues" on the read (and
possible compare) side now??
Yes, fortunately it seems no one used it yet, at least I saw no
bug.
We should put this fix into the -maint branch as well then.
I will, when pushing it. Thanks.
