Date: Mon, 28 Mar 2022 11:11:48 +0530 From: Martin Varghese <martinvarghesenokia@...il.com> To: pshelar@....org, davem@...emloft.net, kuba@...nel.org, pabeni@...hat.com, netdev@...r.kernel.org Cc: Martin Varghese <martin.varghese@...ia.com> Subject: [PATCH net] openvswitch: Fixed nd target mask field in the flow dump. From: Martin Varghese <martin.varghese@...ia.com> 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 <martin.varghese@...ia.com> --- net/openvswitch/flow_netlink.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/net/openvswitch/flow_netlink.c b/net/openvswitch/flow_netlink.c index fd1f809e9bc1..0d677c9c2c80 100644 --- a/net/openvswitch/flow_netlink.c +++ b/net/openvswitch/flow_netlink.c @@ -2201,8 +2201,8 @@ static int __ovs_nla_put_key(const struct sw_flow_key *swkey, 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)); -- 2.18.2
