Lance Richardson 75f01a4c9c openvswitch: maintain correct checksum state in conntrack actions ... When executing conntrack actions on skbuffs with checksum mode CHECKSUM_COMPLETE, the checksum must be updated to account for header pushes and pulls. Otherwise we get "hw csum failure" logs similar to this (ICMP packet received on geneve tunnel via ixgbe NIC): [ 405.740065] genev_sys_6081: hw csum failure [ 405.740106] CPU: 3 PID: 0 Comm: swapper/3 Tainted: G I 4.10.0-rc3+ #1 [ 405.740108] Call Trace: [ 405.740110] <IRQ> [ 405.740113] dump_stack+0x63/0x87 [ 405.740116] netdev_rx_csum_fault+0x3a/0x40 [ 405.740118] __skb_checksum_complete+0xcf/0xe0 [ 405.740120] nf_ip_checksum+0xc8/0xf0 [ 405.740124] icmp_error+0x1de/0x351 [nf_conntrack_ipv4] [ 405.740132] nf_conntrack_in+0xe1/0x550 [nf_conntrack] [ 405.740137] ? find_bucket.isra.2+0x62/0x70 [openvswitch] [ 405.740143] __ovs_ct_lookup+0x95/0x980 [openvswitch] [ 405.740145] ? netif_rx_internal+0x44/0x110 [ 405.740149] ovs_ct_execute+0x147/0x4b0 [openvswitch] [ 405.740153] do_execute_actions+0x22e/0xa70 [openvswitch] [ 405.740157] ovs_execute_actions+0x40/0x120 [openvswitch] [ 405.740161] ovs_dp_process_packet+0x84/0x120 [openvswitch] [ 405.740166] ovs_vport_receive+0x73/0xd0 [openvswitch] [ 405.740168] ? udp_rcv+0x1a/0x20 [ 405.740170] ? ip_local_deliver_finish+0x93/0x1e0 [ 405.740172] ? ip_local_deliver+0x6f/0xe0 [ 405.740174] ? ip_rcv_finish+0x3a0/0x3a0 [ 405.740176] ? ip_rcv_finish+0xdb/0x3a0 [ 405.740177] ? ip_rcv+0x2a7/0x400 [ 405.740180] ? __netif_receive_skb_core+0x970/0xa00 [ 405.740185] netdev_frame_hook+0xd3/0x160 [openvswitch] [ 405.740187] __netif_receive_skb_core+0x1dc/0xa00 [ 405.740194] ? ixgbe_clean_rx_irq+0x46d/0xa20 [ixgbe] [ 405.740197] __netif_receive_skb+0x18/0x60 [ 405.740199] netif_receive_skb_internal+0x40/0xb0 [ 405.740201] napi_gro_receive+0xcd/0x120 [ 405.740204] gro_cell_poll+0x57/0x80 [geneve] [ 405.740206] net_rx_action+0x260/0x3c0 [ 405.740209] __do_softirq+0xc9/0x28c [ 405.740211] irq_exit+0xd9/0xf0 [ 405.740213] do_IRQ+0x51/0xd0 [ 405.740215] common_interrupt+0x93/0x93 Fixes: 7f8a436eaa ("openvswitch: Add conntrack action") Signed-off-by: Lance Richardson <lrichard@redhat.com> Acked-by: Pravin B Shelar <pshelar@ovn.org> Signed-off-by: David S.
