Bug 432308 – app-emulation/libvirt-0.9.13-r1 virsh segfaults on snapshot-list

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Christian Affolter 2012-08-22 13:20:28 UTC]

'virsh snapshot-list <GUEST>' terminates with a segfault on app-emulation/libvirt-0.9.13-r1

The bug is already fixed upstream, see https://www.redhat.com/archives/libvirt-users/2012-July/msg00048.html

I've successfully applied the two patches mentioned in the above post and after re-installing libvirt the snapshot-list command works again.

Fill remote parameters in remoteDomainListAllSnapshots()

This patch fills the domain argument that is sent to the remote side.
This caused a client segfault as the argument was NULL.

virsh: Fix ordering of arguments when calling vshCalloc.

In vshSnapshotListCollect() vshCalloc was called with swapped nmemb and
size argument. This caused division by zero in xalloc_oversized as the
macro doesn't expect size to be zero.

New version is stable where this is fixed.
