When an interface is removed, and another one is created, the nodes from the previous interface are reused. The current code fails when the new interface type differs from the original. It is necessary to update the node runtime, in particular the node function, and the node format function.

2016-10-14FIB2.0: Adjacency complete pull model (VPP-487)Neale Ranns53-1524/+1968
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).

2016-10-13vhost-user: Add reconnect supportDamjan Marion1-0/+1
QEMU 2.7 introduces reconnect support. However it doesn't send last state of last_avail_idx in the SET_VRING_BASE. With this patch we are overriding SET_VRING_BASE with value taken from used->idx. It is a bit hackish as it basically overrides SET_VRING_BASE provided value but it should work in most of the cases. This is what author of reconnect code is also suggesting in his post: https://lists.gnu.org/archive/html/qemu-devel/2016-06/msg01495.html Change-Id: I10e5f401c409d2989bf6c43eaea377800a9c76df Signed-off-by: Damjan Marion <damarion@cisco.com>

2016-10-10FIB2.0: memory leaks during load-balance update (VPP-475)Neale Ranns12-333/+658
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.

2016-10-10Fix double free in af_packet api/cliIvan Kelly2-3/+7
The api was allocating a vector for the name, passing it, then freeing it, on create. The cli allocated, passed then forgot about it. af_packet_create_if was storing a reference to the name, which in the case of the api, meant it was referencing dead memory. On af_packet_delete_if this reference was freed, so in the api case, there was a double free. Also, the cli for delete leaked the name.

2016-10-07unicast RPF for FIB2.0Neale Ranns22-207/+1223
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.
