2016-04-25Add native NETMAP driverDamjan Marion10-5/+1666
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 Coras9-531/+856
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.

2016-04-25Improve mechanism for using loopback interface as BVI for BDsJohn Lo6-78/+63
When loopback interface is configured as BVI, instead of changing its output node from loopN-output to l2-input, the loopN-output node is now kept while its next tx node is changed from ethernet-input to l2-input. The packet setup previously done in bvi_to_l2 as part of l2-input is now performed in the loop output node. This change adds an extra node in the BVI output path but provides the following improvements: 1. IP address/route created on loopback prior to it being configured as BVI will still work properly. The requirement to (re)configure IP/route on loopback after it is configured as BVI is removed. 2. The output stats for loopback interfaces are always provided irrespective of their BVI configuration. 3. The loopback-BVI output stats can be batch updated outside the packet loop in output node, instead of per packet update in l2-input node, making l2-input node more efficient for BVI packets. 4. Restore original node property as implemented in node.c function vlib_node_add_next_with_slot() where next node indices stored in next slots of each node will remain unique. 5. Packet trace for BVI output includes loopN output node which provides useful packet data. Change-Id: I7f5bc72ef953a367363a179088210596881f9e73 Signed-off-by: John Lo <loj@cisco.com>

2016-04-14Rework of DPDK PCI device uio driver binding processDamjan Marion1-301/+57
This is complete rework of DPDK PCI initialization. It drops previous scheme where lspci/route/awk/sed are used and instead sysfs is solely used for discovering Ethernet PCI devices. Criteria for blacklisting device is changed from exsiting routing table entry to simple interface state obtained by SIOCGIFFLAGS ioctl(). It checks for IFF_UP flag, so as long as interface is declared up and even when carrier is down interface will be blacklisted.

2016-04-14Change ARP and IP6-ND nodes to use interface-output node for outputJohn Lo5-89/+24
The current mechanism for setting up arp-input and ip6-discover-neighbor output nodes for interfaces using their interface link up/down callback function is inefficient and has potential timing issue, as observed for bonded interface. Now both nodes will setup output interface sw_if_index in the the sw_if_index[VLIB_TX] field of current packet buffer and then use the interface-ouput node to tx the packet. One side effect is that vlib_node_add_next_with_slot() needs to be modified to allow the same output node-id to be put at the specified slot, even if another slot contain that same node-id already exist. This requirement is caused by BVI support where all loopback interfaces set up as BVIs will have the same output node-id being l2-input while, for output-interface node, the output slot must match the hw_if_index of the interface.

2016-04-02LISP GPE: initial CP commit and DP improvementsFlorin Coras19-705/+5136
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).
