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.

2020-03-03geneve gtpu vxlan vxlan-gpe: VRF-aware bypass nodeNick Zavaritsky1-40/+18
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.

2017-12-13make "test-all" target pass againGabriel Ganne1-0/+9
The "test-all" target is still never called as part of any continuous test (as it probably should) but at least it can now be expected to succeed. VXLAN-GPE: * decapsulate Ethernet to "l2-input" instead of "ethernet-input" otherwise the inner mac address get checked against the interface one (external) and packet gets dropped (mac mismatch) * set packet input sw_if_index to unicast vxlan tunnel for learning TEST: * VXLAN: * reduce the number of share tunnels: => reduce test duration by half => no functional change * VXLAN-GPE: * fix test TearDown() cli: command is "show vxlan-gpe" only * remove vxlan-gpe specific tests as the were a duplicated of the BridgeDomain one and already inherited. * disable test_mcast_rcv() and test_mcast_flood() tests * P2PEthernetAPI: * remove test: "create 100k of p2p subifs" there already is a "create 1k p2p subifs" so this one is a load test and not a unit test.

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.
