2016-11-21Convergence ImprovementsNeale Ranns12-37/+380
addressing convergence times when interface is shut. 1) prioritise the registered callback handlers. Add FIB convergence handler as high priority 2) hook the FIB convergence call-back into HW link down. 3) don't schedule a walk of a FIB node if it has no children 4) Checks at fib_path_t to prevent unnecessary walks, that it prevent the same information propagting the graph multiple times.

2016-11-17Fixup Path weights of 0Neale Ranns3-253/+681
A path wight of 0 is a meaningless value. We can either reject it and thus expect CLI/API clients to always write a non-zero value, or we can accept it and assume the intent was a weight of 1 - this fix does the latter.

2016-11-16Add an ability to punt all unknown UDP traffic to the hostAlexander Popovsky (apopovsk)4-32/+88
By default, VPP replies with ICMP error: port unreachable when receives an ‘unknown’ UDP (destination port with no registered listener) packet. An existing punt() API is extended to accept ALL (~0) as a L4 port number and if used redirects all ‘unknown’ UDP packets to the host. New ‘all’ option is added to the “set punt udp” CLI as well.

2016-11-16VPP-521: Classify API enhancement to redirect traffic to pre-defined VRFSteve Shin4-35/+159
Ingress packets are punted to the “Input ACL node” where traffic is classified based on n-tuple keys. If no matched session is found from the classify tables, then it will be passed to “the lookup node” for normal packet forwarding. If a classify session is hit from one of classify tables, then packet vnet buffer field sw_if_index[VLIB_TX] will be updated to the new FIB index used for subsequent IP lookup for this packet.

2016-11-10VXLAN tunnel encap forwarding optimization with FIB 2.0John Lo7-370/+490
Optimize VXLAN encap node so that vxlan4-encap node is used for IP4 and vxlan6-encap node is used for IP6 underlay. Also stack the VXLAN encap nodes to the appropriate FIB IP4 or IP6 load-balance node instead of ip4/ip6-lookup node to save IP lookup operation. For VXLAN decap node, check VXLAN header FLAGS field for each packet and remove the code to support decap-next for IP4 or IP6. These decap- next values were intended for experimentation purposes and not needed any more since VXLAN-GPE tunnel is supported. The decap-next field is still kept in API for backward compatibility and its value has no effect. Decap next for both vxlan4-decap and vxlan6-decap nodes is always l2-input node.

2016-11-09devices: create dummy device-input node to keep nexts in syncDamjan Marion11-29/+31
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.

From logical point, if first packet is ipv4, and second packet is ipv6. When first packet failed, the procedure will skip key6_1 setting. This will lead to second packet's failure. But here the graph node only process either ipv4 or ipv6 packets completely. So it is not an issue here. This patch only make the packet processig's logic clear. It is just a cosmetic change.
