[Bug 1116337] [NEW] libnl-route-3 produces segmentation fault in libvirt

[Hendrik Schwartke]

Public bug reported:

libvirtd is crashing with a segmentation fault when listing available domains and dumping an interface description at the same time.
The segmentation fault is thrown in rtnl_link_get in the libnl-route-3 library (libnl-route-3-200 3.2.7-4).

How to reproduce:
- Create a domain and start it
- Call "while [ 1 ]; do virsh  list --all ; done" on one terminal
- Call "virsh iface-dumpxml eth0" a few times on another terminal

Ubuntu version: 12.04.2 LTS

Using the latest version of libnl3 (commit
506020ae99377ce45992d225e3b2917ee7b45b77) libvirt works without any
problems.

** Affects: ifenslave-2.6 (Ubuntu)
