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>

2018-08-01vxlan:optimize cached entry compareEyal Bari1-9/+5
the bihash key compare was doing the extra step of loading both keys into vector regs and comparing those - instead of using the temporary values created. Change-Id: Ic557bfa56cd6aa60c71e7f28c880f85e1eb1e6ec 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>
