  "message": "vxlan: fix oops in dev_fill_metadata_dst\n\nSince the commit 0c1d70af924b (\"net: use dst_cache for vxlan device\")\nvxlan_fill_metadata_dst() calls vxlan_get_route() passing a NULL\ndst_cache pointer, so the latter should explicitly check for\nvalid dst_cache ptr. Unfortunately the commit d71785ffc7e7 (\"net: add\ndst_cache to ovs vxlan lwtunnel\") removed said check.\n\nAs a result is possible to trigger a null pointer access calling\nvxlan_fill_metadata_dst(), e.g. with:\n\novs-vsctl add-br ovs-br0\novs-vsctl add-port ovs-br0 vxlan0 -- set interface vxlan0 \\\n\ttype\u003dvxlan options:remote_ip\u003d192.168.1.1 \\\n\toptions:key\u003d1234 options:dst_port\u003d4789 ofport_request\u003d10\nip address add dev ovs-br0 172.16.1.2/24\novs-vsctl set Bridge ovs-br0 ipfix\u003d@i -- --id\u003d@i create IPFIX \\\n\ttargets\u003d\\\"172.16.1.1:1234\\\" sampling\u003d1\niperf -c 172.16.1.1 -u -l 1000 -b 10M -t 1 -p 1234\n\nThis commit addresses the issue passing to vxlan_get_route() the\ndst_cache already available into the lwt info processed by\nvxlan_fill_metadata_dst().\n\nFixes: d71785ffc7e7 (\"net: add dst_cache to ovs vxlan lwtunnel\")\nSigned-off-by: Paolo Abeni \u003cpabeni@redhat.com\u003e\nAcked-by: Jiri Benc \u003cjbenc@redhat.com\u003e\nSigned-off-by: David S.
