2016-04-25Improve mechanism for using loopback interface as BVI for BDsJohn Lo1-4/+5
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>

2016-04-14Rework of DPDK PCI device uio driver binding processDamjan Marion7-109/+1227
This is complete rework of DPDK PCI initialization. It drops previous scheme where lspci/route/awk/sed are used and instead sysfs is solely used for discovering Ethernet PCI devices. Criteria for blacklisting device is changed from exsiting routing table entry to simple interface state obtained by SIOCGIFFLAGS ioctl(). 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 Lo1-5/+4
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.

2016-04-06Do not listen unless configured with cli-listen.Ed Warnicke1-4/+5
I noticed while mucking about with lsof that vpp was listening on port 5000. telnet 0 5000 revealed that it was listening for the cli on that port. Digging into the code, it turns out that if you do not configure cli-listen (Example: unix { cli-listen localhost:5002 } ) Then vpp is listening on the first available port starting at port 5000 anyway. This is a simple patch to *not* listen unless configured to do so. Change-Id: Id7f6f4d69e0a1642d2767849a90b21f38f21ecaa Signed-off-by: Ed Warnicke <eaw@cisco.com>

2016-03-02Remove spurious call to unix_physmem_init(...)Dave Barach1-2/+0
It turns out that unix_physmem_init(...) has been effectively disabled for a very long time. The vnet library supplied a weak symbol override for the vlib_app_physmem_init(...) which returned 1, meaning "do nothing." When we switched libvnet.a -> libvnet.so, the symbol override stopped working. Presto: unix_physmem_init(...) romps all over the data set up by vlib_buffer_pool_create(...), leading to ASSERT failures and/or bus errors, but only when using worker threads. Even then, the failure depended in some complicated way on library dynamic load order. We should remove .../vlib/vlib/unix/physmem.c entirely once we're sure we'll never want it back.

2016-02-18Add jumbo frames support to non-dpdk vhost interfaces.Pierre Pfister3-0/+165
This code provided inter-VM (2 cores per VM) throughput of 22Gbps using iperf through VPP (1 core) with 9k frames. With the same setup and pktgen running on both sides, it reached 5Mpps with no packets drop (Equivalent to before the patch). During the tests the average vector length was about 1, which likely means that VPP is not the bottleneck. The patch also includes some generic functions for vlib buffers allowing for chained buffer construction whether or not DPDK is enabled.
