[libvirt] [PATCH 2/2] bridge: don't crash on bandwidth unplug with no bandwidth

If networkUnplugBandwidth is called on a network which has no bandwidth defined, print a warning instead of crashing. This can happen when destroying a domain with bandwith if bandwidth was removed from the network after the domain was started. https://bugzilla.redhat.com/show_bug.cgi?id=975359 --- src/network/bridge_driver.c | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/src/network/bridge_driver.c b/src/network/bridge_driver.c index f7c2470..72a3f70 100644 --- a/src/network/bridge_driver.c +++ b/src/network/bridge_driver.c @@ -4808,6 +4808,11 @@ networkUnplugBandwidth(virNetworkObjPtr net, if (iface->data.network.actual && iface->data.network.actual->class_id) { + if (!net->def->bandwidth || !net->def->bandwidth->in) { + VIR_WARN("Network %s has no bandwidth but unplug requested", + net->def->name); + goto cleanup; + } /* we must remove class from bridge */ new_rate = net->def->bandwidth->in->average; -- 1.8.1.5
