2016-04-29Add lisp-gpe ip6 data-plane supportFlorin Coras11-755/+1679
The implementation mimics that of the ip4 data-plane. Therefore, a new lgpe-ip6-lookup lookup node is introduced for ip6 source lookups, a lisp-gpe-ip6-input node for decapsulating ip6 encapsulated packets and the tx function of the lisp-gpe interface is updated to support any mix of v4 and v6 in underlay and overlay.

2016-04-29Clean up per-thread mheap setup.Dave Barach1-2/+0
The stats thread was sharing the main mheap when we started at least one worker or I/O thread, but ran on its own mheap when we started 0 worker + io threads. Net of this change; if a VLIB_REGISTER_THREAD instance specifies a per-thread mheap, a per-thread mheap will be provided. Otherwise, threads share the main heap. The stats thread now uses the main heap. Simpler is better. Change-Id: I1fff0dd66ae8f7dfe44923f702734e2832b55b09 Signed-off-by: Dave Barach <dbarach@cisco.com>

2016-04-28VXLAN over IPv6.Chris Luke6-166/+628
Refactors the VXLAN node to work with both IPv4 and IPv6 transports. There is a discussion thread for this change at https://lists.fd.io/pipermail/vpp-dev/2016-March/000279.html Note that this changes the binary configuration API to support both address families; each address uses the same memory for either address type and a flag to indicate which is in use. This also includes changes to the Java API to support both address families. The CLI and VAT syntax remains unchanged; the code detects whether an IPv4 or an IPv6 address was given. Configuration examples: IPv4 CLI: create vxlan tunnel src 192.168.1.1 dst 192.168.1.2 vni 10 encap-vrf-id 0 decap-next l2 IPv6 CLI: create vxlan tunnel src 2620:124:9000::1 dst 2620:124:9000::2 vni 16 encap-vrf-id 0 decap-next l2 IPv4 VAT: vxlan_add_del_tunnel src 192.168.1.1 dst 192.168.1.2 vni 10 encap-vrf-id 0 decap-next l2 IPv6 VAT: vxlan_add_del_tunnel src 2620:124:9000::1 dst 2620:124:9000::2 vni 16 encap-vrf-id 0 decap-next l2 TODO: The encap path is not as optimal as it could be.

2016-04-28Track number of ethernet vlans in a frameChris Luke8-7/+83
Adds flags to the packet buffer to track the number of VLANs in the current Ethernet frame. We use two bits to signify 0, 1 or 2 VLANs. The value 3 signififies an unknown quantity of VLANs, which includes "three or more" which is not widely supported. We place the bits in the vlib_buffer section; that is not the opaque section, so that all subordinate nodes can use it. For background, see the discussion thread at https://lists.fd.io/pipermail/vpp-dev/2016-March/000354.html The helper macro ethernet_buffer_header_size(buffer) uses these bits stored in "buffer" to calculate the Ethernet header size. The macro ethernet_buffer_set_vlan_count(buffer, count) sets the appropriate bit values based on the number in "count". By current frame we are referring to the case where a packet that arrives from the wire is carrying an encapsulated Ethernet packet. Once decapsulated that inner packet becomes the current frame. There are two places where this value is set; For most Ethernet frames this will be in the "ethernet-input" node when that node parses the Ethernet header. The second place is whenever vnet_update_l2_len() is used to update the layer 2 opaque data. Typically this function is used by nodes just before they send a packet into l2-input. These bits are zeroed in vlib_buffer_init_for_free_list() meaning that wherever the buffer comes from they have a reasonable value (eg, if ip4/ip6 generates the packet.) Primarily this VLAN counter is used by nodes below "ethernet- input" and "l2-input" to determine where the start of the current Ethernet header is. There is opaque data set by "ethernet-input" storing the offset of the current Ethernet header but, since this is opaque, it's not usable by downstream nodes. Previously several nodes have made assumptions regarding the location of the Ethernet header, including that it is always at the start of the packet buffer (incorrect when we have encapsulated packets) or that it is exactly sizeof(ethernet_header_t) away (incorrect when we have VLAN tags.) One notable case where this functionality is required is in ip6_neighbor when it generates a response to a received neighbor soliciation request; it reuses the incoming Ethernet header in-situ and thus needs to reliably know where that header begins. Also, at the suggestion of Dave Barach, this patch removes definition of HGSHM bits in the buffer flags since they are unused and unlikely to ever be.

2016-04-26MTU: set interface mtu tapMohsin Kazmi5-33/+57
This patch introduces standard command line 'set interface mtu' for setting the MTU for tap devices. It allows user to set the mtu in between 68 to 65535 bytes aligned to what linux kernel supports for tun/tap devices. Right now tapcli set the same MTU size for each tap interface. But it should be set and configure to per interface rather than per tap instance. Change-Id: I81b7f3ad95ca56d585907ff8f51d9935a428e01b Signed-off-by: Mohsin Kazmi <sykazmi@cisco.com>

This patch is more or less a port of I71f3ba0c8192 to IPv6. In practice it allows creating a route via a neighbor which is not resolved yet. It also adds static flag to IPv6 neighbor entries. And as Damjan suggested, it formalizes ip46_address_t by using the IPv4 embedded IPv6 address format.

2016-04-25Convert lisp-gpe encap to interface tx nodeFlorin Coras9-531/+856
With this change, one lisp-gpe interface is created per vrf/overlay tenant and its tx node is used as encapsulator (or tunnel ingress). For all intents and purposes, the tx node inherits all functions previously performed by the lisp-gpe-encap node and it maintains said node's position in lisp-gpe's data-path graph. Chiefly, this opens the possibility to chain interface features, like IPSec, transparently with LISP. Furthermore, it brings basic data plane support for vrfs and LISP instance-ids (or virtual network instances as per RFC7364). Other changes include improvements to lisp-gpe enable and disable sequences and corresponding API/VAT fixes.

2016-04-25Improve mechanism for using loopback interface as BVI for BDsJohn Lo6-78/+63
When loopback interface is configured as BVI, instead of changing its output node from loopN-output to l2-input, the loopN-output node is now kept while its next tx node is changed from ethernet-input to l2-input. The packet setup previously done in bvi_to_l2 as part of l2-input is now performed in the loop output node. This change adds an extra node in the BVI output path but provides the following improvements: 1. IP address/route created on loopback prior to it being configured as BVI will still work properly. The requirement to (re)configure IP/route on loopback after it is configured as BVI is removed. 2. The output stats for loopback interfaces are always provided irrespective of their BVI configuration. 3. The loopback-BVI output stats can be batch updated outside the packet loop in output node, instead of per packet update in l2-input node, making l2-input node more efficient for BVI packets. 4. Restore original node property as implemented in node.c function vlib_node_add_next_with_slot() where next node indices stored in next slots of each node will remain unique. 5. Packet trace for BVI output includes loopN output node which provides useful packet data. Change-Id: I7f5bc72ef953a367363a179088210596881f9e73 Signed-off-by: John Lo <loj@cisco.com>
