[ovs-dev] [PATCH 3/3] xlate: call tnl_neigh_snoop() from terminate_native_tunnel()

Move tunnel neigh snooping from do_xlate_actions() to terminate_native_tunnel() in order to keep ARP neighbor cache clean. Furthermore filter ARP reply and Neighbor Advertisement messages addressing tunnel endpoint. Signed-off-by: Zoltan Balogh ---

[ovs-dev] [PATCH 2/3] tests: modify ARP snoop tests for tunneling with clone

If ARP reply is received on LOCAL port of underlay bridge, then packets pushed to tunnel port in overlay bridge will be dropped in the underlay. This commit modifies this by receiving ARP replies on a different dummy port. This fix is needed for an upcomming correction for ARP snooping.

[ovs-dev] [PATCH 1/3] ofproto-dpif-sflow: propagate actions within clone

By avoiding Tx recirculation and embracing tnl_push action within clone, the tunnel metadata is not propagated. Unless clone action is handled in the dpif_sflow_read_actions() function as well. This commit resolves this issue. In addition, some sflow data needs to be stored and restored in

[ovs-dev] [PATCH 0/3] Fix tunnel neighbor cache population

Currenlty, OVS snoops any ARP or ND packets in any bridge and populates the tunnel neighbor cache with the retreived data. For instance, when ARP reply originated by a tenant is received on an overlay bridge, the ARP message is snooped and tunnel neighbor cache is filled with tenant data, however

Re: [ovs-dev] [PATCH v1] OVN: Add external_ids to NAT and Logical_Router_Static_Route tables.

Lucas asked me about backporting this one, as OpenStack would start making use of it with an OVS 2.8 update if available. The schema change seems pretty harmless. The catch is that this also updated the schema version number from "5.8.1" to "5.8.2", while branch-2.8 has "5.8.0". master includes
