2016-12-07Prevent re-entrant walks on an adjacency.Neale Ranns1-40/+57
The re-entrant walks were caused when the walk from an IP adj updated a fib_netry with an MPLS adj which in turn triggers a walk of the IP adj. Re-entrant walks do unnecessary work. also fixed a walk merge issue where the encountered walk should only be checked for equivalence woth the most recent alk, not any in the list.

is an attribute of the packet and checked where necessary Add a flag to the vnet_buffer to indicate a packet is locally originated. Then in the rewrite nodes we can check this flag and not perform the TTL decrement. The switch path cost is expected to be fractions of a clock - the flags will be hot in the cache. The cehcks are necessary to due the requirements that VPP must be able to emit an IP packet with TTL=255.

Added support for multicast vxlan tunnels which are used for bridge domain flooding instead of flooding the all unicast tunnels in the bridge domain. features added: * conditional flooding to some of the BD members - based on existance of multicast tunnel member * added local multicast adjacency - multicast packets are handled as the same as unicast - based on src (unicast) address * refactored some of vxlan tunnel creation code - to unify ip4/6 handling Change-Id: I60cca4124265a8dd4f6b2d6ea8701e52e7c1baa4 Signed-off-by: Eyal Bari <ebari@cisco.com>

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.

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.

2016-11-10VXLAN tunnel encap forwarding optimization with FIB 2.0John Lo1-0/+2
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.

2016-10-14FIB2.0: Adjacency complete pull model (VPP-487)Neale Ranns4-43/+58
Change the adjacency completion model to pull not push. A complete adjacency has a rewirte string, an incomplete one does not. the re-write string for a peer comes either from a discovery protocol (i.e. ARP/ND) or can be directly derived from the link type (i.e. GRE tunnels). Which method it is, is interface type specific. For each packet type sent on a link to a peer there is a corresponding adjacency. For example, if there is a peer 10.0.0.1 on Eth0 and we need to send to it IPv4 and MPLS packets, there will be two adjacencies; one for the IPv4 and one for the MPLS packets. The adjacencies are thus distinguished by the packets the carry, this is known as the adjacency's 'link-type'. It is not an L3 packet type, since the adjacency can have a link type of Ethernet (for L2 over GRE). The discovery protocols are not aware of all the link types required - only the FIB is. the FIB will create adjacencies as and when they are required, and it is thus then desirable to 'pull' from the discovery protocol the re-write required. The alternative (that we have now) is that the discovery protocol pushes (i.e. creates) adjacencies for each link type - this creates more adjacencies than we need. To pull, FIB now requests from the interface-type to 'complete' the adjacency. The interface can then delegate to the discovery protocol (on ethernet links) or directly build the re-write (i.e on GRE).

2016-10-10FIB2.0: memory leaks during load-balance update (VPP-475)Neale Ranns8-282/+593
some other fixes and enhancemets to address failures in the IPv6 Scale testing: - The rate at which VPP sends ARP/ND requests, 1 per-millisecond, is too high. This is reduced to 1 every 10 ms. probably still too high. - If an ARP/ND response is received that does not contain a change to the known MAC address, no further processing is done. - Added stats to get info about the async FIB walks. - When walking FIB entries and performing a load-balance update, it is not necessary to re-insert the LB in the forwarding table.

2016-10-07unicast RPF for FIB2.0Neale Ranns12-71/+880
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.
