dpdk-input was dropping packets with bad ip-checksum on l2 interfaces Change-Id: Ife5b52766bb71e878b1da6e94ae7b8a1e59fc478 Signed-off-by: Eyal Bari <ebari@cisco.com>
2018-03-11dpdk-input node packet trace intermittent on IP forwading pathJohn Lo1-36/+37
Packet trace initiated by dpdk-input node would occasionally not fully function if next node is ip4-input. Change packet trace saving order in the quad-loop so "sho trace" will display trace in packet receive order. Fold calling of vlib_trace_buffer() into dpdk_add_trace().

dpdk_rx_next_from_packet_start is equivalent to dpdk_rx_next_from_etype and seems to have no side effects Change-Id: I629dadfbfb35ad1f5c7198e7824883ae4bd6abaa Signed-off-by: Eyal Bari <ebari@cisco.com>

2017-09-25Fix sending GARP/NA on Bonded Interface Active/Backup Link Up/DownJohn Lo1-0/+2
For bonded interface in Active/Backup mode (mode 1), we need to send a GARP/NA packet, if IP address is present, on slave link state change to up or down to help with route convergence. The callback from DPDK happens in a separate thread so we need to make sure RPC call is used to signal the send_garp_na process in the main thread. Also need to fix DPDK polling so the slave links are not polled. Change-Id: If5fd8ea2d28c54dd28726ac403ad366386ce9651 Signed-off-by: John Lo <loj@cisco.com>
2017-07-14Introduce l{2,3,4}_hdr_offset fields in the buffer metadataDamjan Marion1-1/+7
To save space in the first cacheline following is changed: - total_length_not_including_first_buffer moved to the 2nd cacheline. This field is used only when VLIB_BUFFER_TOTAL_LENGTH_VALID and VLIB_BUFFER_NEXT_PRESENT are both set. - free_list_index is now stored in 4bits inside flags, which allows up to 16 free lists. In case we need more we can store index in the 2nd cachelin Change-Id: Ic8521350819391af470d31d3fa1013e67ecb7681 Signed-off-by: Damjan Marion <damarion@cisco.com>

2017-04-07MPLS McastNeale Ranns1-1/+1
1 - interface-DPO Used in the Data-plane to change a packet's input interface 2 - MPLS multicast FIB entry Same as a unicast entry but it links to a replicate not a load-balance DPO 3 - Multicast MPLS tunnel Update MPLS tunnels to use a FIB path-list to describe the endpoint[s]. Use the path-list to generate the forwarding chain (DPOs) to link to . 4 - Resolve a path via a local label (of an mLDP LSP) For IP multicast entries to use an LSP in the replication list, we need to decribe the 'resolve-via-label' where the label is that of a multicast LSP. 5 - MPLS disposition path sets RPF-ID For a interface-less LSP (i.e. mLDP not RSVP-TE) at the tail of the LSP we still need to perform an RPF check. An MPLS disposition DPO performs the MPLS pop validation checks and sets the RPF-ID in the packet. 6 - RPF check with per-entry RPF-ID An RPF-ID is used instead of a real interface SW if index in the case the IP traffic arrives from an LSP that does not have an associated interface.

2017-04-06Use thread local storage for thread indexDamjan Marion1-15/+17
This patch deprecates stack-based thread identification, Also removes requirement that thread stacks are adjacent. Finally, possibly annoying for some folks, it renames all occurences of cpu_index and cpu_number with thread index. Using word "cpu" is misleading here as thread can be migrated ti different CPU, and also it is not related to linux cpu index.

2017-03-14Fix packet trace output: dpdk_rx_trace must decode the actual ethertypeDave Barach1-1/+31
As opposed to rubbish (typically) 14 octets past the ethertype. Also fix buffer error code setup in dpdk-input node single loop. Change-Id: Ide7c4097d3bb91e62749ed4e1d69a7b4b90225de Signed-off-by: Dave Barach <dbarach@cisco.com> Signed-off-by: John Lo <loj@cisco.com>
