2016-11-09devices: create dummy device-input node to keep nexts in syncDamjan Marion1-1/+1
device-input feature arc requires that all input-nodes have nexts in sync. packet-generator tends to call vlib_node_add_next when new stream is created and that puts nexts out of sync. With this change all input node are siblings of device-input node so call to vlib_node_add_next(...) will install same next to the whole family.

2016-10-10ipfix: add classification nodes for flow statistics (VPP-204)Juraj Sloboda1-1/+4
In order to have meaningfull IPFIX implementation we should be able to classify all packets flowing through vpp. But existing IPv4 and IPv6 classifier nodes are called only if destination IP address is local to vpp. This commit adds new IPv4 and IPv6 classifier nodes that should be used for collecting flow statistics.

2016-10-07unicast RPF for FIB2.0Neale Ranns1-0/+1
In a heirarchical FIB performing a unicast RPF check would require the traversal of the data-plane graph to seek out all the adjacency objects and then read those to find their interface. This is not efficient. Instead, for each path-list we construct a list of unique input interfaces and link this uRPF-list against the entry in the prefix table. In the data-plane the uRPF list can be retrieved from the load-balance lookup result and the RPF check is a simple and efficient walk across the minimal interface list. The uRPF-list is maintained as the routing heirarchy changes, in a similar way to the data-plane object graph. We also provide a knob to allow an arbitrary prefix to pass the loose check.

2016-09-28DPDK HQoS: Enable Hierarchical Scheduler in VPPJasvinder Singh1-0/+1
This commit extends the vpp framework with new thread type "hqos-threads" that runs the Hierarchical Quality of Service (HQoS) scheduler associted with output interface. HQoS Scheduler prioritize the packets from different users and ensures sufficient bandwidth to pass the more important traffic. At high level, HQoS scheduler is a buffer that can temporarily store a large number of packets. In otherwords, it is a collection of large number of queues organized into hierarchy of 5 levels; the port (i.e. the physical interface) is at the root of the hierarchy followed by the subport (a set of users), the pipes (individual users), the traffic classes (each with a strict priority) and at the leaves, the queues. In each HQoS scheduler, three operations are performed; classification (setting HQoS port, subport, pipe, traffic class and queue within traffic class from packet fields), enqueue (selecting HQoS queue for the packet, and to drop the packet if the queue is full) and dequeue (schedule the packet based on its length and available credits, and handover the scheduled packet to the output interface). In vpp, the number of hqos threads will be equal to cpu cores specified in corelist-hqos-threads parameter cpu section of the vpp configuration file. One hqos thread can run HQoS for multiple output interfaces. A particular HQoS instance is initialised with default parameters required to configure hqos port, subport, pipe and queues. Some of them can be re-configured in run-time through CLI commands as well binary APIs. Following illustrates the sample startup configuration file with 4x worker threads feeding 2x hqos threads that handle each HQoS for 1x output interface. For more details on HQoS configuration please refer to DPDK Programmer's Guide. dpdk { socket-mem 16384,16384 dev 0000:02:00.0 { num-rx-queues 2 hqos } dev 0000:06:00.0 { num-rx-queues 2 hqos } num-mbufs 1000000 } cpu { main-core 0 corelist-workers 1, 2, 3, 4 corelist-hqos-threads 5, 6 } Change-Id: I635c3395a7c4ddf0a239ef77b0b0a31a6dfc4767 Signed-off-by: Cristian Dumitrescu <cristian.dumitrescu@intel.com> Signed-off-by: Jasvinder Singh <jasvinder.singh@intel.com>

2016-06-17Dynamically compute ip feature subgraph orderDave Barach1-0/+2
This change-set enables plugins to add themselves to the ip4/ip6 feature subgraphs without having to modify core vpp engine code at all. Add VNET_IP4/IP6_UNICAST/MULTICAST_FEATURE_INIT macros which express the required ordering constraints, and off you go. Along the way, added an implementation of Warshall's algorithm to vppinfra; to compute the positive transitive closure of a relation. In this case, the relation is "feature A runs before feature B." With that in hand, ip_feature_init_cast(...) computes a partial order across the set of configured feature subgraph nodes. In unit-testing, we discovered VPP-145 - ip4/6 inacl wiped out vnet_buffer(b)->ip>current_config_index, which exists in main. So, we fixed that by moving b->trace_index, adding b->current_config_index, and removing the ip opaque union current_config_index.

2016-06-16VPP-19: Split the lookup.h IP_LOOKUP_NEXT enum.Ole Troan1-1/+0
IP4 and IP6 nodes currently shares the adj->lookup_next_index. That has some issues, e.g. that one has to add non-functional nodes like ip4-hop-by-hop and that anyone dynamically adding nodes to any of the IP4/IP6 lookup nodes must ensure they add themselves to all relevant nodes to ensure next index consistency. This patch splits the IP_LOOKUP_NEXT into separate enums for IP4 and IP6 with a common part for next-nodes used by both. It sets up other IP nodes as siblings to avoid inconsistencies. This allows IP4 and IP6 lookup next nodes to evolve independently. The adj->lookup_next_index is still shared, assuming that an IP4 adjacency isn't used by an IP6 graph node.

2016-04-25Convert lisp-gpe encap to interface tx nodeFlorin Coras1-1/+1
With this change, one lisp-gpe interface is created per vrf/overlay tenant and its tx node is used as encapsulator (or tunnel ingress). For all intents and purposes, the tx node inherits all functions previously performed by the lisp-gpe-encap node and it maintains said node's position in lisp-gpe's data-path graph. Chiefly, this opens the possibility to chain interface features, like IPSec, transparently with LISP. Furthermore, it brings basic data plane support for vrfs and LISP instance-ids (or virtual network instances as per RFC7364). Other changes include improvements to lisp-gpe enable and disable sequences and corresponding API/VAT fixes.

2016-04-02LISP GPE: initial CP commit and DP improvementsFlorin Coras1-2/+21
Control Plane ------------- In essence, this introduces basic support for map-request/reply processing, the logic to generate and consume such messages, including SMRs, a control-plane backend, consisting of an eid-table, locator and locator-set tables, and CLI to interact with it. Naturally, we can now serialize/deserialize LISP specific types: addresses, locators, mappings, messages. An important caveat is that IPv6 support is not complete, both for EIDs and RLOCs. Functionally, the DP forwards all packets it can't handle to the CP (lisp_cp_lookup node) which takes care of obtaining a mapping for the packet's destination from a pre-configured map-resolver using the LISP protocol. The CP then caches this information and programs the DP such that all new packets with the same destination (or within the covering prefix) are encapsulated to one of the locators retrieved in the mapping. Ingress traffic-engineering is not yet supported. Data Plane ---------- First of all, to enable punting to the CP, when LISP GPE is turned on a default route that points to lisp_cp_lookup is now inserted. The DP also exposes an API the CP can use to program forwarding for a given mapping. This mainly consists in allocating a tunnel and programming the FIB such that all packets destined to the mapping's prefix are forwarded to a lisp-gpe encapsulating node. Another important change done for lisp forwarding is that both source and destination IP addresses are considered when encapsulating a packet. To this end, a new FIB/mtrie is introduced as a second stage, src lookup, post dst lookup. The latter is still done in the IP FIB but for source-dest entries, in the dest adjacency the lookup_next_index points to a lisp lookup node and the rewrite_header.sw_if_index points to the src FIB. This is read by the lisp lookup node which then walks the src mtrie, finds the associated adjacency, marks the buffer with the index and forwards the packet to the appropriate next node (typically, lisp-gpe-encap).
