2019-12-17ip: Protocol Independent IP NeighborsNeale Ranns1-2/+15
Type: feature - ip-neighbour: generic neighbour handling; APIs, DBs, event handling, aging - arp: ARP protocol implementation - ip6-nd; IPv6 neighbor discovery implementation; separate ND, MLD, RA - ip6-link; manage link-local addresses - l2-arp-term; events separated from IP neighbours, since they are not the same. vnet retains just enough education to perform ND/ARP packet construction. arp and ip6-nd to be moved to plugins soon.

2019-10-02ethernet: dmac filter checks secondary mac addrsMatthew G Smith1-0/+7
Maintain a list of secondary MAC addresses on ethernet_interface_t. In ethernet-input dmac filtering, If packets do not match the primary interface hardware address, check to see if they match the other addresses.

2019-05-16init / exit function orderingDave Barach1-0/+1
The vlib init function subsystem now supports a mix of procedural and formally-specified ordering constraints. We should eliminate procedural knowledge wherever possible. The following schemes are *roughly* equivalent: static clib_error_t *init_runs_first (vlib_main_t *vm) { clib_error_t *error; ... do some stuff... if ((error = vlib_call_init_function (init_runs_next))) return error; ... } VLIB_INIT_FUNCTION (init_runs_first); and static clib_error_t *init_runs_first (vlib_main_t *vm) { ... do some stuff... } VLIB_INIT_FUNCTION (init_runs_first) = { .runs_before = VLIB_INITS("init_runs_next"), }; The first form will [most likely] call "init_runs_next" on the spot. The second form means that "init_runs_first" runs before "init_runs_next," possibly much earlier in the sequence. Please DO NOT construct sets of init functions where A before B actually means A *right before* B. It's not necessary - simply combine A and B - and it leads to hugely annoying debugging exercises when trying to switch from ad-hoc procedural ordering constraints to formal ordering constraints.

2019-03-21BVI InterfaceNeale Ranns1-1/+1
a new dedicated BVI interface as opposed to [re]using a loopback. benefits: - removes ambiguity over the purpose of a loopback interface - TX node dedicated to BVI only functions. Change-Id: I749d6b38440d450ac5b909a28053c75ec9df946a Signed-off-by: Neale Ranns <nranns@cisco.com>

2017-10-24Add extern to *_main global variable declarations in header files.Dave Wallace1-1/+1
- Global variables declared in header files without the use of the 'extern' keword will result in multiple instances of the variable to be created by the compiler -- one for each different source file in which the the header file is included. This results in wasted memory allocated in the BSS segments as well as potentially introducing bugs in the application.

2017-07-14Introduce l{2,3,4}_hdr_offset fields in the buffer metadataDamjan Marion1-2/+1
To save space in the first cacheline following is changed: - total_length_not_including_first_buffer moved to the 2nd cacheline. This field is used only when VLIB_BUFFER_TOTAL_LENGTH_VALID and VLIB_BUFFER_NEXT_PRESENT are both set. - free_list_index is now stored in 4bits inside flags, which allows up to 16 free lists. In case we need more we can store index in the 2nd cachelin Change-Id: Ic8521350819391af470d31d3fa1013e67ecb7681 Signed-off-by: Damjan Marion <damarion@cisco.com>

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.
