2018-08-13Multiarch handling in different constructor macrosDamjan Marion1-4/+0
This significantly reduces need for ... in multiarch code. Simply constructor macros will jost create static unused entry if CLIB_MARCH_VARIANT is defined and that will be optimized out by compiler.

2018-05-31dpdk: Decoupling the meaning of xd->device_index in dpdk_pluginRui Cai1-1/+1
Prior to the change, dpdk plugin assumes xd->device_index is used both as index for internal dpdk_main->devices array and DPDK port index to call into DPDK APIs. However, when running on top of Failsafe PMDs, DPDK port index range may no longer be contiguous (as noted: http://dpdk.org/ml/archives/dev/2018-March/092375.html for related changes in DPDK). Because this, dpdk plugin can no longer iterate through all available DPDK ports with a for 0->rte_eth_dev_count() loop and the assumption of device_index no longer holds. This is part of initial effort to enable vpp running over dpdk on failsafe PMD in Microsoft Azure(3/4).

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().

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.
