2021-02-19policer: move handoff checks into policer codeBrian Russell1-30/+12
The IP punt policer currently checks if it needs to do worker thread handoff based on the thread index stored in the policer. Move this functionality into the policer code so it can be common for all users of the policer.

2021-02-15vlib: refactor checksum offload supportMohsin Kazmi4-38/+37
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.

2021-02-15ip: Path MTUNeale Ranns5-13/+1351
Type: feature Support setting the MTU for a peer on an interface. The minimum value of the path and interface MTU is used at forwarding time. the path MTU is specified for a given peer, by address and table-ID. In the forwarding plane the MTU is enfored either: 1 - if the peer is attached, then the MTU is set on the peer's adjacency 2 - if the peer is not attached, it is remote, then a DPO is added to the peer's FIB entry to perform the necessary fragmentation.

2021-02-12policer: remove SSE2 prefixBrian Russell1-3/+3
The policer code uses a naming convention of prefixing a lot of its definitions with "SSE2" when in fact there is nothing SSE2 specific about them. This is confusing so remove the prefix. Unfortunately it has to stay in the API definitions for backward compatibility.

2021-02-08tunnel: support copying TTL and flow label from inner to outerNeale Ranns2-8/+43
Type: feature The added functionality is to support copying TTL and flow label from inner to outer. The .api was extened to support expressing this and also adding a common tunnel endpoint type. i find it best to make API changes in one patch so there are less versions of the API.

A NAT sub-plugin doing statically configured match/rewrite on IP4 input or output. It's stateless (no connection tracking). Currently it supports rewriting of SA, DA and TCP/UDP ports. It should be simple to add new rewrites if required. API: pnat_binding_add, pnat_binding_del, pnat_bindings_get, pnat_interfaces_get CLI: set pnat translation interface <name> match <5-tuple> rewrite <5-tuple> {in|out} [del] show pnat translations show pnat interfaces Trying a new C based unit testing scheme. Where the graph node is tested in isolation. See pnat/pnat_test.c. Also added new cmake targets to generate coverage directly.

2020-09-04ip: enhance vtep4_check of tunnel by vector wayZhiyong Yang1-0/+42
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.

In one's complement, there are two representations of zero: the all zero and the all one bit values, often referred to as +0 and -0. See RFC 1624 section 3 for more details. This used to be taken care of in ip4_header_checksum(), but it is no longer the case. The check ip->checksum == ip4_header_checksum (ip) is no longer correct in the -0 case. Always use ip4_header_checksum_is_valid() instead (which behaves correctly since 9a79a1ab931c3b5a7ae07d6f0fcfef7c4368a2c4).
