[libvirt] Regarding libvirtd crash in virDomainLookupByName(..) similar to bug 903238/915353/924756

[Udayan Bapat (ubapat)]

Hello All,


I work in Cisco Virtualization team and I found this email list from libvirt.org

We are hitting a random libvirtd crash with a traceback during guest shutdown -


#3  0x00007f4a34a2d4ad in malloc_printerr (action=2, str=0x7f4a34acb682 "corrupted double-linked list", ptr=<value optimized out>) at malloc.c:5949

I believe this TB is quite similar to the one reported by various Redhat bugs mentioned in the subject. We are running libvirt version 0.8.4. I understand this issue has been fixed in the later versions of libvirt but due to business reasons, we are not able to upgrade it yet. Hence I was trying to look for a patch that might have fixed the issue.


I found this link that supposedly describes the patch but it is not accessible to people outside red hat network (I think!)

https://bugzilla.redhat.com/show_bug.cgi?id=915353


It would be really helpful if you could point me out a patch if it exists!


Thank you in advance.
