2016-03-18vnet_classify: Handle non-aligned vectors and various bugfixesPierre Pfister2-98/+136
classifier used to crash when packet data was not aligned. This commit also includes: - writer lock initialization bugfix - CLI help was missing opaque-index - ip_input_acl was applying the mask on buffer->data instead of packet head On a side note, my tests failed to show any improvements when using SSE. Further tests might be interesting to see if they actually perform better. Change-Id: Ic34eecd6a2226919121ffce2fe4324506deee52f Signed-off-by: Pierre Pfister <ppfister@cisco.com>

2016-03-14fix declaration of symbol of different sizeJean-Mickael Guerin27-64/+58
I got many warnings at the link step with gcc version 5.3.1 20160225 (Ubuntu 5.3.1-10ubuntu2): /usr/bin/ld: Warning: size of symbol `cop_input_node' changed from 112 in vnet/cop/.libs/cop.o to 168 in vnet/cop/.libs/node1.o /usr/bin/ld: Warning: size of symbol `ethernet_input_node' changed from 112 in vnet/.libs/interface.o to 136 in vnet/ethernet/.libs/node.o /usr/bin/ld: Warning: size of symbol `l2output_node' changed from 112 in vnet/l2/.libs/l2_efp_filter.o to 120 in vnet/l2/.libs/l2_output.o /usr/bin/ld: Warning: size of symbol `srp_input_node' changed from 112 in vnet/srp/.libs/format.o to 136 in vnet/srp/.libs/node.o /usr/bin/ld: Warning: size of symbol `vxlan_encap_node' changed from 112 in vnet/vxlan/.libs/vxlan.o to 128 in vnet/vxlan/.libs/encap.o /usr/bin/ld: Warning: size of symbol `vxlan_input_node' changed from 112 in vnet/vxlan/.libs/vxlan.o to 144 in vnet/vxlan/.libs/decap.o ... Looking at vlib_node_registration_t, I think the reason is that the char * next_nodes[] could be bigger where the variable is defined in .c file. We should mark global variables as external in header files. Some of them can be made static.

2016-03-14Do not use hugepages if none are available.Stefan Kobza1-2/+2
In case socket-mem was set to <1024 and no 1G page long hupepages were available, the condition was evaluated in unexpected manner. In other words use_1g == 1, and that fails later in mount(). This patch makes sure this is prevented - if there are no pages_available, do not even try to use that pagesize.

2016-03-02Remove spurious call to unix_physmem_init(...)Dave Barach1-11/+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.

2016-02-25Add support of Ethernet link bonding utilizing DPDK link bondingJohn Lo3-2/+61
poll mode driver library. The bonded interfaces to be created on VPP startup is specified in the dpdk section of startup.conf or qn.conf, using DPDK EAL command. Following is an example of a dpdk section white listing PCI addressses of 4 ethernet interfacess to be under VPP control plus two bonded interface and the PCI addresses of the slaves in each: dpdk { socket-mem 1024,1024 dev 0000:0f:00.0 dev 0000:10:00.0 dev 0000:11:00.0 dev 0000:12:00.0 vdev eth_bond0,mode=2,slave=0000:0f:00.0,slave=0000:11:00.0,xmit_policy=l34 vdev eth_bond1,mode=2,slave=0000:10:00.0,slave=0000:12:00.0,xmit_policy=l34 } Note that only balance XOR (mode 2) is supported and "xmit_policy=l34" specifies to use layer 3 SIP/DIP and layer 4 Sport/Dport for load balance. Using "xmit_policy=l2" for SMAC/DMAC or "xmit_policy=l23" for SMAC/DMAC and SIP/DIP should also work. Change-Id: Iaf6438686fa20cce893cb5a823b76e2886b4360b Signed-off-by: John Lo <loj@cisco.com>

2016-02-25Add live migration support to (non-dpdk) vhost-user driverYoann Desmouceaux2-8/+144
This patch adds live migration support to vhost interfaces, by supporting the VHOST_F_LOG_ALL feature. When qemu starts a migration, it will negotiate this feature, and provide a fd for a "dirty log" shared mem space. This log is a bitmap representing pages in the device memory. Whenever we touch memory pointed by a "desc" vring, or modify a "used" vring, we log the corresponding page in the bitmap. This allows qemu to send the dirty page to the destination host. See https://github.com/qemu/qemu/blob/master/docs/specs/vhost-user.txt, ยง "Live migration" for more details. In addition to this, this code provides support for the VHOST_USER_F_PROTOCOL_FEATURES feature, and to VHOST_USER_{GET,SET}_PROTOCOL_FEATURES and VHOST_USER_SET_VRING_ENABLE messages, required for live migration.

If all Qs are enabled, each thread queues packet in their own TX-Q of the VHOST_USER interface, boosting performance.

2016-02-18Add jumbo frames support to non-dpdk vhost interfaces.Pierre Pfister1-290/+229
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.
