IPv6 nd target mask was not getting populated in flow dump. In the function __ovs_nla_put_key the icmp code mask field was checked instead of icmp code key field to classify the flow as neighbour discovery. ufid:bdfbe3e5-60c2-43b0-a5ff-dfcac1c37328, recirc_id(0),dp_hash(0/0), skb_priority(0/0),in_port(ovs-nm1),skb_mark(0/0),ct_state(0/0), ct_zone(0/0),ct_mark(0/0),ct_label(0/0), eth(src=00:00:00:00:00:00/00:00:00:00:00:00, dst=00:00:00:00:00:00/00:00:00:00:00:00), eth_type(0x86dd), ipv6(src=::/::,dst=::/::,label=0/0,proto=58,tclass=0/0,hlimit=0/0,frag=no), icmpv6(type=135,code=0), nd(target=2001::2/::, sll=00:00:00:00:00:00/00:00:00:00:00:00, tll=00:00:00:00:00:00/00:00:00:00:00:00), packets:10, bytes:860, used:0.504s, dp:ovs, actions:ovs-nm2 Fixes: e64457191a25 (openvswitch: Restructure datapath.c and flow.c) Signed-off-by: Martin Varghese Link: https://lore.kernel.org/r/20220328054148.3057-1-martinvarghesenokia@gmail.com Signed-off-by: Paolo Abeni Signed-off-by: Greg Kroah-Hartman --- net/openvswitch/flow_netlink.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) --- a/net/openvswitch/flow_netlink.c +++ b/net/openvswitch/flow_netlink.c @@ -2201,8 +2201,8 @@ static int __ovs_nla_put_key(const struc icmpv6_key->icmpv6_type = ntohs(output->tp.src); icmpv6_key->icmpv6_code = ntohs(output->tp.dst); - if (icmpv6_key->icmpv6_type == NDISC_NEIGHBOUR_SOLICITATION || - icmpv6_key->icmpv6_type == NDISC_NEIGHBOUR_ADVERTISEMENT) { + if (swkey->tp.src == htons(NDISC_NEIGHBOUR_SOLICITATION) || + swkey->tp.src == htons(NDISC_NEIGHBOUR_ADVERTISEMENT)) { struct ovs_key_nd *nd_key; nla = nla_reserve(skb, OVS_KEY_ATTR_ND, sizeof(*nd_key));
