2021-02-15vlib: refactor checksum offload supportMohsin Kazmi1-10/+16
Type: refactor This patch refactors the offload flags in vlib_buffer_t. There are two main reasons behind this refactoring. First, offload flags are insufficient to represent outer and inner headers offloads. Second, room for these flags in first cacheline of vlib_buffer_t is also limited. This patch introduces a generic offload flag in first cacheline. And detailed offload flags in 2nd cacheline of the structure for performance optimization.

2021-01-14vxlan: Protect against tunnel config where source is not localNeale Ranns1-2/+11
Type: fix If a tunnel's source is not local then post encap VPP will attempt to receive (via ip4-local) that packet, things go wrong from there. The fix is when stacking the encap forwarding don't accept a receive DPO. This approach is taken, rather than rejecting bad tunnels, because the 'local-ness' of the tunnel's source can change and we can't reject tunnels that were once correctly configured but are no longer. the user will quickly discover their mistake as traffic won't pass.

2020-09-04ip: enhance vtep4_check of tunnel by vector wayZhiyong Yang1-12/+32
This patch aims to improve decap performance by reducing expensive hash_get callings as less as possible using AVX512 on XEON. e.g. vxlan, vxlan_gpe, geneve, gtpu. For the existing code, if vtep4 of the current packet match the last vtep4_key_t well, expensive hash computation can be avoided and the code returns directly. This patch improves tunnel decap multiple flows case greatly by leveraging 512bit vector register on XEON accommodating 8 vtep4_keys. It enhances the possiblity of avoiding unnecessary hash computing once hash key of the current packet hits any one of 8 in the 512bit cache. The oldest element in vtep4_cache_t is updated in round-robin order. vlib_get_buffers is also leveraged in the meanwhile.

2020-08-31flow: code refactorChenmin Sun1-3/+7
This is the code refactor for vnet/flow infra and the dpdk_plugin flow implementation. The main works of the refactor are: 1. Added two base flow type: VNET_FLOW_TYPE_IP4 and VNET_FLOW_TYPE_IP6 as the base the flow type 2. All the other flows are derived from the base flow types 3. Removed some flow types that are not currently supported by the hardware, and VPP won't leverage them either: IP4_GTPU_IP4, IP4_GTPU_IP6, IP6_GTPC, IP6_GTPU, IP6_GTPU_IP4, IP6_GTPU_IP6 4. Re-implemented the vnet/flow cli as well as the dpdk_plugin implementation 5. refine cli prompt 6. refine display info in command "show flow entry" Type: refactor Signed-off-by: Chenmin Sun <chenmin.sun@intel.com> Change-Id: Ica5e61c5881adc73b28335fd83e36ec1cb420c96

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>
