2019-12-20vxlan: reuse inner packet flow hash for tunnel outer header load balanceShawn Ji1-0/+7
Type: fix Several tunnels encapsulation use udp as outer header and udp src port is set by inner header flow hash, such as gtpu, geneve, vxlan, vxlan-gbd Since flow hash of inner header is already been calculated, keeping it to vnet_buffere[b]->ip.flow_hash should save load-balance node work to select ECMP uplinks.

2019-12-05vxlan: fix vxlan hw offload issueChenmin Sun1-1/+3
Type: fix Since Vxlan hw offload jumps the ethernet-input node, so needs to adjust the data offset accordingly In original code, the current_data is 0 when arriving vxlan-flow-input node(due to no graph node before it, except the dpdk-input), so this code block cannot find the correct vxlan header: enum { payload_offset = sizeof (ip4_vxlan_header_t) }; vlib_buffer_advance (b0, payload_offset); see code in src/vnet/vxlan/decap.c, function vxlan4_flow_input_node This patch fixes this issue Signed-off-by: Chenmin Sun <chenmin.sun@intel.com> Change-Id: Iab4af7a7dc3b69a117a4c9ea1c59662669a6438c

2019-07-19fib: FIB Entry trackingNeale Ranns1-7/+7
Instead of all clients directly RR sourcing the entry they are tracking, use a deidcated 'tracker' object. This tracker object is a entry delegate and a child of the entry. The clients are then children of the tracker. The benefit of this aproach is that each time a new client tracks the entry it doesn't RR source it. When an entry is sourced all its children are updated. Thus, new clients tracking an entry is O(n^2). With the tracker as indirection, the entry is sourced only once.

2019-06-18fib: fib api updatesNeale Ranns1-7/+5
Enhance the route add/del APIs to take a set of paths rather than just one. Most unicast routing protocols calcualte all the available paths in one run of the algorithm so updating all the paths at once is beneficial for the client. two knobs control the behaviour: is_multipath - if set the the set of paths passed will be added to those that already exist, otherwise the set will replace them. is_add - add or remove the set is_add=0, is_multipath=1 and an empty set, results in deleting the route. It is also considerably faster to add multiple paths at once, than one at a time: vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.11 100000 routes in .572240 secs, 174751.80 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.12 100000 routes in .528383 secs, 189256.54 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.13 100000 routes in .757131 secs, 132077.52 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.14 100000 routes in .878317 secs, 113854.12 routes/sec vat# ip_route_add_del 1.1.1.1/32 count 100000 multipath via 10.10.10.11 via 10.10.10.12 via 10.10.10.13 via 10.10.10.14 100000 routes in .900212 secs, 111084.93 routes/sec Change-Id: I416b93f7684745099c1adb0b33edac58c9339c1a Signed-off-by: Neale Ranns <neale.ranns@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Paul Vinciguerra <pvinci@vinciconsulting.com>

Using memcpy instead of complex specific copy logic. This simplify the implementation and also improve perf slightly.

After applying the patch, 2~3 cycles per pkt for vxlan4_encap can be saved on Haswell. It will bring a lot of benefits on DVN platform too.

2018-02-15Optimize GRE Tunnel and add support for ERSPAN encapJohn Lo1-4/+0
Change GRE tunnel to use the interface type where the same encap node is used as output node for all GRE tunnels, instead of having dedicated output and tx node for each tunnel. This allows for more efficient tunnel creation and deletion at scale tested at 1000's of GRE tunnels. Add support for ERSPAN encap as another tunnel type, in addition to the existing L3 and TEB types. The GRE ERSPAN encap supported is type 2 thus GRE encap need to include sequence number and GRE- ERSPAN tunnel can be created with user secified ERSPAN session ID. The GRE tunnel lookup hash key is updated to inclue tunnel type and session ID, in addition to SIP/DIP and FIB index. Thus, GRE-ERSPAN tunnel can be created, with the appropriate session ID, to be used as output interface for SPAN config to send mirrored packets. Change interface naming so that all GRE tunnels, irrespective of tunnel type, uses "greN" where N is the instance number. Removed interface reuse on tunnel creation and deletion to enable unfied tunnel interface name. Add support of user specified instance on GRE tunnel creation. Thus, N in the "greN" interface name can optionally be specified by user via CLI/API. Optimize GRE tunnel encap DPO stacking to bypass load-balance DPO node since packet output on GRE tunnel always belong to the same flow after 5-tupple hash.
