2020-11-25api: vat2 and json autogeneration for api messagesOle Troan1-3/+3
VAT2: A completely auto-generated replacement of VAT. Reads input message in JSON from stdin and outputs received messages in JSON. A VAT2 plugin is automatically built for a .api file. There no longer a need for a separate _test.c. Example: vat2 show_version {} { "_msgname": "show_version_reply", "retval": 0, "program": "vpe", "version": "21.01-rc0~411-gf6eb348a6", "build_date": "2020-11-19T09:49:25", "build_directory": "/vpp/autogen3" } vat2 sw_interface_dump '{"sw_if_index": -1, "name_filter_valid": 0, "name_filter": ""}' [{ "_msgname": "sw_interface_details", "sw_if_index": 0, "sup_sw_if_index": 0, "l2_address": "00:00:00:00:00:00", "flags": "Invalid ENUM", "type": "IF_API_TYPE_HARDWARE", "link_duplex": "LINK_DUPLEX_API_UNKNOWN", "link_speed": 0, "link_mtu": 0, "mtu": [0, 0, 0, 0], "sub_id": 0, "sub_number_of_tags": 0, "sub_outer_vlan_id": 0, "sub_inner_vlan_id": 0, "sub_if_flags": "Invalid ENUM", "vtr_op": 0, "vtr_push_dot1q": 0, "vtr_tag1": 0, "vtr_tag2": 0, "outer_tag": 0, "b_dmac": "00:00:00:00:00:00", "b_smac": "00:00:00:00:00:00", "b_vlanid": 0, "i_sid": 0, "interface_name": "local0", "interface_dev_type": "local", "tag": "" }] This is the first phase and vat2 is not integrated in packaging yet.

2020-09-18fib: skip byte swap on n_paths in mroute detailsMatthew Smith1-2/+2
Type: fix While preparing to send a ip_mroute_details API message, the number of paths for a multicast route is stored in an int in send_ip_mroute_details(). Before the value in the int is copied into the field n_paths in the API message, the byte order is swapped. This results in n_paths getting set to 0. Change the int to a u8 and omit the byte swap so API clients can receive data on multicast route paths.

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.

2020-09-01ip: fix ip zero checksum verificationBenoît Ganne3-8/+9
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).

Fix and optimize DMAC check in ethernet-input node to utilize NIC or driver which support L3 DMAC-filtering mode so that DMAC check can be bypassed safely for interfaces/sub-interfaces in L3 mode. Checking of interface in L3-DMAC-filtering state to avoid DMAC check require the following: a) Fix interface driver init sequence for devices which supports L3 DMAC-filtering to indicate its capability and initialize interface to L3 DMAC-filtering state. b) Fix ethernet_set_flags() function and its associated callback flags_change() functions registered by various drivers in interface infra to provide proper L3 DMAC filtering status. Maintain interface/sub-interface L3 config count so DMAC checks can be bypassed if L3 forwarding is not setup on any main/sub-interfaces.
