2016-06-28VPP-48 Fixes for ip4/6 ttl checks and icmp responsesChris Luke6-72/+244
This patch fixes a few minor things: - Previously ip[46]_input was rejecting packets with an input TTL (hop limit) of one; this was not correct behavior. Packets that are bound for this device can validly have a TTL of one. - ip[46]_forward was not generating an ICMP TTL expired message if the act of decrementing the TTL caused it to become zero. This was not previously an issue because ip[46]_input was filtering packets where this could happen. - udp_local was not generating ICMP Port Unreachable messages if UDP packets arrived for a port that is not listened to. This is typically the signal that "traceroute" uses to terminate its search. Together these fixes mean that traceroute probes transiting a VPP node, or are targetted toward a VPP node, now work as expected.

2016-06-28Reduce ring size for dpdk NICs and overtal mem footprintDamjan Marion3-7/+7
Size of interface descriptor rings have direct impact on Last Level Cache utilization, and can significantly affect performance. So generally having smaller ring size is good idea as long as there is enough buffer in the ring to accomodate line rate. Here we are reducing rings sizes to 1024 which is still bigger than lab verified 512 buffers per ring. Indirectly, this also affects memory footprint, as we can have smaller buffer allocation, which is now 16384 (previously it was 32768) This patch also fixes issue with i40e vector PMD which was leaking buffers when previous default ring sizes were set.

2016-06-24Add admin-up flag to L2TP tunnels and start tunnels set to downPierre Pfister4-6/+42
L2TP tunnels use virtual interfaces but directly send packets to l2-input node (not ethernet-input). This node requires a bridge-domain to be associated with the interface. Past code was immediatly turning the interface up, but some packets could be sent to l2-input without bridge domain between interface creation and association with a bridge domain. The tunnel is now created as down and has to be set up later (typically after being associated with a bridge-domain). Another option would have been to change the api and enforce a bridge-domain to be specified before the tunnel, but this is less flexible for the user.

2016-06-22ARP/NDP does not send solicitation when no source address is availablePierre Pfister6-7/+28
Currently, when the interface has no address assigned to it, VPP crashes as ip_interface_address_for_packet assumes there always is at least one address. This patch checks if an address is available at all. The only part of VPP using it is ARP or NDP. When a neighbor discovery message has to be sent while there is no address assigned on the interace, no solicitation is sent and an error counter is incremented.

When receiving a local ipv6 packet containing an l2tp packet not associated with any session, l2tp node was handling the packet as if provided by an ipv6 feature, hence crashing.

2016-06-19Fix use of lookup_next_index in LISP src/dst FIBFlorin Coras2-12/+79
Adjacencies in LISP src/dst FIB store the index of the LISP output interface (next node after lookup) in the lookup_next_index. Since the values of interface node indexes are not constrained, they can collide with the 'special' adjacencies IP_LOOKUP_NEXT_LOCAL and IP_LOOKUP_NEXT_DROP. As a result, at allocation time, LISP ajacencies may be automatically shared with the previous two, predefined adjacencies and all LISP specific state stored in the rewrite area is lost. This fixes the problem by 'hijacking' the explicit_fib_index instead of the lookup_next_index field.

2016-06-17Dynamically compute ip feature subgraph orderDave Barach19-135/+530
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 Troan11-339/+50
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.
