2020-09-11nat: Fix next feature for ED with multiple workersVladimir Isaev3-2/+25
Multiple (> 1) workers leads to handoff node being enabled. This node pops next feature index to nat.arc_next to make sure that packet will be pushed to the next feature in the arc. But node nat44-ed-in2out-output also pops next feature and changes arc_next. So actual next feature will be skipped in that case. It leads to all nat44-ed-in2out packets being dropped if we have multiple workers (handoff node enabled). To resolve this a new node was added (nat-pre-in2out-output) to fill arc_next in single worker case and multiple worker case is already handled by handoff node.

2020-09-11avf: fix race between avf process node and avf_delete_if(...)Damjan Marion4-18/+34
It may happen that process node is suspended while it waits for response from adminq and during that time CLI or API process can call avf_delete_if. When avf process node resumes, it may happen that device is not there anymeore. This patch delegates interface deletion to process node, so CLI/API process just sends signal instead of deleting device instance itself.

Type: fix VRRP cannot be used on a BVI interface currently because packets sent to the virtual mac address of the VR fail the destination mac check in l2_to_bvi(). Apparently people want to use VRRP on BVI interfaces, so update the check in l2_to_bvi() so that it will check any secondary mac addresses which have been added to the ethernet interface if the destination mac address does not match the primary mac address for the interface. An equivalent check is already done in ethernet_input_inline() for L3 interfaces which are in promiscuous mode.

2020-09-07ipsec: fix padding/alignment for native IPsec encryptionChristian Hopps5-19/+19
Not all ESP crypto algorithms require padding/alignment to be the same as AES block/IV size. CCM, CTR and GCM all have no padding/alignment requirements, and the RFCs indicate that no padding (beyond ESPs 4 octet alignment requirement) should be used unless TFC (traffic flow confidentiality) has been requested. CTR: https://tools.ietf.org/html/rfc3686#section-3.2 GCM: https://tools.ietf.org/html/rfc4106#section-3.2 CCM: https://tools.ietf.org/html/rfc4309#section-3.2 - VPP is incorrectly using the IV/AES block size to pad CTR and GCM. These modes do not require padding (beyond ESPs 4 octet requirement), as a result packets will have unnecessary padding, which will waste bandwidth at least and possibly fail certain network configurations that have finely tuned MTU configurations at worst. Fix this as well as changing the field names from ".*block_size" to ".*block_align" to better represent their actual (and only) use. Rename "block_sz" in esp_encrypt to "esp_align" and set it correctly as well. test: ipsec: Add unit-test to test for RFC correct padding/alignment test: patch scapy to not incorrectly pad ccm, ctr, gcm modes as well - Scapy is also incorrectly using the AES block size of 16 to pad CCM, CTR, and GCM cipher modes.

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
