2021-02-15ip: Path MTUNeale Ranns1-0/+1
Type: feature Support setting the MTU for a peer on an interface. The minimum value of the path and interface MTU is used at forwarding time. the path MTU is specified for a given peer, by address and table-ID. In the forwarding plane the MTU is enfored either: 1 - if the peer is attached, then the MTU is set on the peer's adjacency 2 - if the peer is not attached, it is remote, then a DPO is added to the peer's FIB entry to perform the necessary fragmentation.

2020-12-08fib: Source Address SelectionNeale Ranns1-2/+1
Type: feature Use the FIB to provide SAS (in so far as it is today) - Use the glean adjacency as the record of the connected prefixes = there's a glean per-{interface, protocol, connected-prefix} - Keep the glean up to date with whatever the recieve host prefix is (since it can change) Signed-off-by: Neale Ranns <neale.ranns@cisco.com> Change-Id: I0f3dd1edb1f3fc965af1c7c586709028eb9cdeac
2020-05-04fib: midchain adjacency optimisationsNeale Ranns1-1/+2
Type: improvement - inline some common encap fixup functions into the midchain rewrite node so we don't incur the cost of the virtual function call - change the copy 'guess' from ethernet_header (which will never happen) to an ip4 header - add adj-midchain-tx to multiarch sources - don't run adj-midchain-tx as a feature, instead put this node as the adj's next and at the end of the feature arc. - cache the feature arc config index (to save the cache miss going to fetch it) - don't check if features are enabled when taking the arc (since we know they are) the last two changes will also benefit normal adjacencies taking the arc (i.e. for NAT, ACLs, etc) for IPSec: - don't run esp_encrypt as a feature, instead when required insert this node into the adj's next and into the end of the feature arc. this implies that encrypt is always 'the last feature' run, which is symmetric with decrypt always being the first. - esp_encrpyt for tunnels has adj-midchain-tx as next node Change-Id: Ida0af56a704302cf2d7797ded5f118a781e8acb7 Signed-off-by: Neale Ranns <nranns@cisco.com>

2019-12-17ip: Protocol Independent IP NeighborsNeale Ranns1-1/+1
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.

2017-04-07MPLS McastNeale Ranns1-5/+9
1 - interface-DPO Used in the Data-plane to change a packet's input interface 2 - MPLS multicast FIB entry Same as a unicast entry but it links to a replicate not a load-balance DPO 3 - Multicast MPLS tunnel Update MPLS tunnels to use a FIB path-list to describe the endpoint[s]. Use the path-list to generate the forwarding chain (DPOs) to link to . 4 - Resolve a path via a local label (of an mLDP LSP) For IP multicast entries to use an LSP in the replication list, we need to decribe the 'resolve-via-label' where the label is that of a multicast LSP. 5 - MPLS disposition path sets RPF-ID For a interface-less LSP (i.e. mLDP not RSVP-TE) at the tail of the LSP we still need to perform an RPF check. An MPLS disposition DPO performs the MPLS pop validation checks and sets the RPF-ID in the packet. 6 - RPF check with per-entry RPF-ID An RPF-ID is used instead of a real interface SW if index in the case the IP traffic arrives from an LSP that does not have an associated interface.

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.
