2017-04-07MPLS McastNeale Ranns4-5/+6
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.

2017-04-06Use thread local storage for thread indexDamjan Marion3-11/+12
This patch deprecates stack-based thread identification, Also removes requirement that thread stacks are adjacent. Finally, possibly annoying for some folks, it renames all occurences of cpu_index and cpu_number with thread index. Using word "cpu" is misleading here as thread can be migrated ti different CPU, and also it is not related to linux cpu index.

we should not suppress arps on remote interface instead we should flood them to the local one used shg != 0 to identify packets from remote interfaces and disable arp term l2 input feature for them Change-Id: I701537c05df7451a25ccb5bfc9e2b03ea70cff20 Signed-off-by: Eyal Bari <ebari@cisco.com>

2017-03-17Attached hostsNeale Ranns1-18/+54
allow this config to function: set int ip address loop0 169.254.1.1/32 (the default GW address for attached hosts) set int unnumbered af_packet0 use loop0 ('enable' IP on the host interface) ip route add 192.168.1.1/32 via af_packet0 (where to find the host) repeat for each host and host interface. Inter-host communication is throught the /32 routes. To allow this: 1 - attached host routes have the ATTACHED flag set, so the ARP code accepts then as legitimate sources 2 - unnumbered interfaces inherit the source address from the IP interface Change-Id: Ib66c5f0e848c528f79372813adc3a0c11b50717f Signed-off-by: Neale Ranns <nranns@cisco.com>
2017-03-13Add MAC address check in ethernet-input node if interface in L3 modeJohn Lo1-6/+17
Interface can be in promiscuous mode if more than one of its sub- interface is in L2 mode. In promiscuous mode, L3 interface need to verify DMAC of packet to match that of the interface and drop if not. This check was done on sub-interface only and now also added to main interface path. Fix incorrect MAC addresses in the flow-per-pkt plugin test, which caused it to fail. Fix MAC address usage in BFD tests.

2017-03-03Implement a loopback instance allocation scheme.Jon Loeliger2-12/+117
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 Ranns3-21/+85
- 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.
