[ovs-dev] [PATCH net 1/2] openvswitch: check for null return for nla_nest_start

The call to nla_nest_start in conntrack can lead to a NULL return so it's possible for attr to become NULL and we can potentially get a NULL pointer dereference on attr. Fix this by checking for a NULL return. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=200533 Fixes: 11efd5cb04a1
