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.

2020-06-15vxlan: remove judgement with always trueZhiyong Yang1-27/+15
if ((A | B) == false) it means both A and B are false, so for the following code if (PREDICT_FALSE (!good_udp1)) { if ((flags1 & VNET_BUFFER_F_L4_CHECKSUM_COMPUTED) == 0) { ... } } if ((flags1 & VNET_BUFFER_F_L4_CHECKSUM_COMPUTED) == 0) is always true if the code run it. Remove it. Type: improvement Signed-off-by: Zhiyong Yang <zhiyong.yang@intel.com> Change-Id: I6bd1e9340c7a00089fc1c9ae49773add832d309e
2020-03-03geneve gtpu vxlan vxlan-gpe: VRF-aware bypass nodeNick Zavaritsky1-57/+21
Bypass node MUST NOT intercept a packet if destination IP doesn’t match a local address. However IP address interpretation depends on the VRF, hence bypass node must take that into account. This patch also factors-out common VTEP management and checking code.

2018-10-05vxlan:ip4 decap:remove access to tunnel objectEyal Bari1-163/+142
store local/remote addresses + vrf + vni in hash key store complete decap info in hash value (sw_if_index + next_index + error) this removes the need to access the tunnel object when matching both unicast and mcast. however for mcast handling it requires 3 hash lookups: * one failed unicast lookup (by src+dst addrs) * lookup by mcast(dst) addr . * unicast lookup (tunnel local ip as dst + pkt's src addr) where previously it needed 2: * lookup by src to find unicast tunnel + compare dst to local addr (failing for mcast) * lookup by mcast to find the mcast tunnel Change-Id: I7a3485d130a54194b8f7e2df0431258db36eceeb Signed-off-by: Eyal Bari <ebari@cisco.com>

2017-04-06Use thread local storage for thread indexDamjan Marion1-5/+5
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.

2017-01-31Add vxlan-bypass feature to IP6 forwarding pathJohn Lo1-173/+282
Add vxlan-bypass feature which can be enabled on the IP6 underlay interface which receive VXLAN packets to accelerate VXLAN decap processing. The CLI to enable/disable it is: set interface ip6 vxlan-bypass <interface> [del] The vxlan-bypass feature is already supported on the IP4 underlay interface. The CLI to enable/disable it is: set interface ip vxlan-bypass <interface> [del] Move vxlan-bypass API/CLI support code from decap.c to vxlan.c. Also fixed two issues in the VXLAN decap path in the vxlan-input node: 1. Add verification of VXLAN packet FIB index with the encap-vrf-id of the VXLAN tunnel. 2. Fix checking of VXLANoIPv6 packet mcast DIP against that of the IP6 mcast VXLAN tunnel. Change-Id: I2bad4074a468c48fbb8bb5ac64f6437190756ed2 Signed-off-by: John Lo <loj@cisco.com>
