2020-09-04vrrp: improve RFC compliance for ARP/NDMatthew Smith2-38/+48
Type: fix The ARP/ND feature nodes reply to requests for a VR virtual IP address when a VR is in the master state. If the VR is in the backup state, the request is passed to the next node on the feature arc. This can cause an incorrect response to be sent. If some other feature (e.g. NAT) causes a virtual IP address to be configured as a "local" address on the system, a later node on the feature arc may respond to an ARP/ND request with the real MAC address of the interface. RFC 5798 says that a router must respond to ARP/ND requests for VR virtual IP addresses with the VR virtual MAC address. And it says a router must not respond to ARP/ND requests for VR virtual IP addresses when the VR is in the backup state. Ensure that ARP/ND requests for VR virtual IP addresses are dropped when in the backup state rather than allowing them to continue on the feature arc where another node may end up responding. In order to do this, enable/disable the feature nodes when leaving or entering the init state instead of the master state.

2020-09-04ipsec: fix trace of GRE_teb packetsChristian Hopps1-2/+5
The issue is not easily hit. When GRE_teb packets are received the post crypto processing adjusts the l2.l2_len value in the vnet_buffer opaque data. This is overwriting the ipsec opaque data. Later the trace code fetches the sa_index from the ipsec opaque data. It's just an accident that this currently works, if the ipsec data is changed so that the sa_index moves around it will be overwritten by the l2_len modification. Indeed, this was found b/c local development changes had moved the sa_index so it was over-lapping with the l2_len memory space, and the UT failed.

2020-09-04ip: enhance vtep4_check of tunnel by vector wayZhiyong Yang6-48/+173
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.

2020-09-03crypto: SW scheduler async crypto enginePiotrX Kleski8-71/+1027
Type: feature This patch adds new sw_scheduler async crypto engine. The engine transforms async frames info sync crypto ops and delegates them to active sync engines. With the patch it is possible to increase the single worker crypto throughput by offloading the crypto workload to multiple workers. By default all workers in the system will attend the crypto workload processing. However a worker's available cycles are limited. To avail more cycles to one worker to process other workload (e.g. the worker core that handles the RX/TX and IPSec stack processing), a useful cli command is added to remove itself (or add it back later) from the heavy crypto workload but only let other workers to process the crypto. The command is: - set sw_scheduler worker <idx> crypto <on|off> It also adds new interrupt mode to async crypto dispatch node. This mode signals the node when new frames are enqueued as opposed to polling mode that continuously calls dispatch node. New cli commands: - set crypto async dispatch [polling|interrupt] - show crypto async status (displays mode and nodes' states) Signed-off-by: PiotrX Kleski <piotrx.kleski@intel.com> Signed-off-by: DariuszX Kazimierski <dariuszx.kazimierski@intel.com> Reviewed-by: Fan Zhang <roy.fan.zhang@intel.com> Change-Id: I332655f347bb9e3bc9c64166e86e393e911bdb39

2020-09-01ip: fix ip zero checksum verificationBenoît Ganne10-19/+20
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).
