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>

2016-04-26Port glean neighbor entry support to IPv6Pierre Pfister12-74/+343
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.

DPDK 16.04 introduced new config parameter RTE_ARCH_X86 which was missing in the dpdk/Makefile That caused issues with virtio devices on older kernels (observed on 3.13.0). This patch changes the source of generated config so it will also include all defines in config/defconfig_TARGET file.

In order to make it easier for folks who have existing Centos or Ubuntu boxes to utilize the same 'Getting started' scripting that is used in Vagrant, as well as enable us to use that scripting in CI, broke up bootstrap.sh into update.sh - Things like apt-get update build.sh - Install any dependencies and build vpp clearinterfaces.sh - Clean off any non-default gateway interfaces. Used by vagrant. run.sh - Start vpp as a service on the box. A user (or CI) just wanting to get going and build on an existing Ubuntu or Centos image (ie, not via vagrant) can simply run build.sh Change-Id: I8f19342f163cad07c6c05def943a5fb8e394b879 Signed-off-by: Ed Warnicke <eaw@cisco.com>

2016-04-25Convert lisp-gpe encap to interface tx nodeFlorin Coras12-539/+950
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 Lo7-82/+68
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>

2016-04-22Add a vpp_restart commandDave Barach4-5/+250
vpp_restart solves the problem of restarting vpp and not exiting until the new vpp instance is sufficiently established to allow immediate binary API connections. The point is to avoid using arbitrary "sleep N" commands e.g. in CSIT shell scripts. We send SIGTERM to the current vpp process, and expect / depend on the process-monitor du jour to remove the vpp-api shared-memory segment. vpp_restart exits w/ status 0 if all is well, non-zero upon failure. In trying to make vpp_restart reliable, we discovered a recently-introduced heap corruption bug in .../dpdk/init.c, which caused vpp to crash on startup once every 20 times on a particular rig. If possible, we should check /var/log/syslog for evidence of unexpected multiple restarts during regression-testing.

It checks for IFF_UP flag, so as long as interface is declared up and even when carrier is down interface will be blacklisted.

2016-04-14Change ARP and IP6-ND nodes to use interface-output node for outputJohn Lo6-94/+28
The current mechanism for setting up arp-input and ip6-discover-neighbor output nodes for interfaces using their interface link up/down callback function is inefficient and has potential timing issue, as observed for bonded interface. Now both nodes will setup output interface sw_if_index in the the sw_if_index[VLIB_TX] field of current packet buffer and then use the interface-ouput node to tx the packet. One side effect is that vlib_node_add_next_with_slot() needs to be modified to allow the same output node-id to be put at the specified slot, even if another slot contain that same node-id already exist. This requirement is caused by BVI support where all loopback interfaces set up as BVIs will have the same output node-id being l2-input while, for output-interface node, the output slot must match the hw_if_index of the interface.
