2017-02-08Fix source address reachability check for ip6 local packetsAkshayaNadahalli1-1/+23
Currently ip6 local check fails with error - source lookup miss if route to source of packet is over a dpo object such as load balance - recurssive route, tunnel adj - GRE, SR etc. So unless packet source is of a directly connected neibhor or has route with both interface and nexthop specified, it will be dropped. Fix is to check urpf list and if at least one link exists in the list, then allow packets to be processed, else drop.

2017-01-27IP Multicast FIB (mfib)Neale Ranns20-224/+440
- IPv[46] mfib tables with support for (*,G/m), (*,G) and (S,G) exact and longest prefix match - Replication represented via a new replicate DPO. - RPF configuration and data-plane checking - data-plane signals sent to listening control planes. The functions of multicast forwarding entries differ from their unicast conterparts, so we introduce a new mfib_table_t and mfib_entry_t objects. However, we re-use the fib_path_list to resolve and build the entry's output list. the fib_path_list provides the service to construct a replicate DPO for multicast. 'make tests' is added to with two new suites; TEST=mfib, this is invocation of the CLI command 'test mfib' which deals with many path add/remove, flag set/unset scenarios, TEST=ip-mcast, data-plane forwarding tests. Updated applications to use the new MIFB functions; - IPv6 NS/RA. - DHCPv6 unit tests for these are undated accordingly.

2017-01-05FIB memory leaks (VPP-578)Neale Ranns4-8/+29
1) vec_free the fe_srcs of a fib_entry_t when the fib_entry_t is itself reed 2) in the load-balance fixup if a drop path is required add this to a new vector of next-hops 'fixed_nhs'. This vector is managed by the load-balance function. The caller continues to manage its own set. The function is now const implying that the caller is safe to assume the next-hops do not change.
