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.

2016-04-29Add lisp-gpe ip6 data-plane supportFlorin Coras1-0/+1
The implementation mimics that of the ip4 data-plane. Therefore, a new lgpe-ip6-lookup lookup node is introduced for ip6 source lookups, a lisp-gpe-ip6-input node for decapsulating ip6 encapsulated packets and the tx function of the lisp-gpe interface is updated to support any mix of v4 and v6 in underlay and overlay.

2016-04-25Add native NETMAP driverDamjan Marion1-0/+14
This is first drop of native NETMAP driver. It is mainly tested with NETMAP pipes but also support for native interfaces should work. New CLI: create netmap [<intf name>|valeXXX:YYY] [hw-addr <mac>] [pipe] [master|slave] Following example creates NETMAP pipe where VPP acts as master: create netmap name vale00:vpp1 pipe master then NETMAP pkt-gen tool can be used to send traffic: pkt-gen -i vale00:vpp1}0 -f tx Change-Id: Ie0ddaa5facc75285b78467420e8a9f9c8dfc39e5 Signed-off-by: Damjan Marion <damarion@cisco.com>
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).
