2017-03-03Implement a loopback instance allocation scheme.Jon Loeliger1-1/+5
To support creating loopback interfaces with a specific instance number, a new CREATE_LOOPBACK_INSTANCE API call with flag is_specified and value user_instance is introduced. Presumably the existing CREATE_LOOPBACK API message will be obsoleted and revmoved. The VAT cli commands can now mention and format the new field as 'instance %d' data. If no instance number is named, the old call CREATE_LOOPBACK is used to maintain backward compatibility. However, if the instance is named, the new CREATE_LOOPBACK_INSTANCE message will be used. Both the dynamically allocated and user-requested instance number are tracked in a bitvector. If is_specified is 0, the next free instance will be used.. A request for a specific instance number will be granted if it is available. On error, the value ~0 is returned.

2017-01-27IP Multicast FIB (mfib)Neale Ranns1-0/+2
- 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.
