2019-01-03Prevent dropping ARP packetsXavier Simonart5-13/+47
JIRA: SAMPLEVNF-152 When system is overloaded, ARP packets were sometimes dropped, as any other packets. This was causing two issues: - The count of TX non dataplane packets was wrong - If many consecutive ARP packets were dropped, the underlying switch might see its ARP timer expiring, causing performance degradation (packets being broadcasted). ARP packets are now always sent as no-drop. Change-Id: I9a86cbf8c4b56a178f86bc789153f1fa49ddf73f Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2018-12-20Do not add count of non dataplane packets to dropped countXavier Simonart1-1/+6
RX packets count = TX count + dropped (handled + discarded) count + non dataplane packets count. Hence non dataplane packets such as unexpected packets (e.g. dhcp request) should not b considerded as handled.

2018-12-14Fix handing configuration error (missing tx port or ring in gen mode)Xavier Simonart1-1/+2
Gen mode requires a tx ring or a tx port. A configuration without those should gracefully report an error. This was causing a crash. Change-Id: Ia30d4d4c87a694da1dfed86587f90b9199c493ab Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>

2018-12-13Fix arp handling when master core is on socket 1Xavier Simonart1-1/+1
When master core was on socket 1, the rings setup to exchange messages related to arp between dataplane cores and master core was not properly setup, resulting in arp not working. Change-Id: Icc08df81f2e39e53de7c212248cdc7b78d7e2618 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2018-12-13Add support for zero packet loss in PROX L3 mode.Xavier Simonart3-24/+109
In L3 mode, prox is extracting IP destination address in the packets. It uses this destination address to find the MAC address. If the MAC address is not found, it sends a ARP request. It also sends ARP request when it realizes that some timeout expired. However, PROX was using the mbuf of the existing packets (to be forwarded) to send the ARP. This resulted in packet loss. Now PROX is generating ARP requests using mbuf from an ARP mempool. Some clean up was also done.

2018-12-13Fix issue in l3 mode when no arp reply was receivedXavier Simonart1-7/+26
When no arp reply was received in l3 mode, the requesting core continuously sends ARP requests every seconds (which is correct). But master core was keeping a list of all requests, while all those requests are the same, resulting in potential table overflow.

2018-12-05Add support for VLAN insert and strippingXavier Simonart2-0/+19
JIRA: SAMPLEVNF-149 VLAN can be enabled on a port by adding "vlan=yes" in the port section. When VLAN is enabled on a port, then DEV_RX_OFFLOAD_VLAN_STRIP and DEV_TX_OFFLOAD_VLAN_INSERT are enabled (if device supports it). This will cause VLAN to be stripped from any packets received with the proper tag, and VLAN to be added for any packets being transmitted. The VLAN ID themselves are configured through the physical function using something like (where ens801f1 isthe PF): ip link set ens801f1 vf 0 vlan 1111 Change-Id: I945c87b0c18565da479ecaa08e5ffce91232a7ce Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>

2018-10-28Add support for counting non dataplane related packetsXavier Simonart8-5/+114
When performing some zero packet loss performance testing on dataplane, it is important (not) to count non dataplane packets. For instance, one might receive uexpected packets from a switch, or ARP packets. Or one might need to transmit ARP packets. Such packets should not be counted as dataplane packets as for thse packets there is no 1:1 mapping between transmitted packets and received packets. To support this, the counters reporting numbers of transmitted and received packets remain unchanged but two new counters have been added to PROX, counting respectively number of received and number of transmitted non-dataplane packets. On RX side, packets are counsidered as non-dataplane if being ARP or if they do not countain the proper signature On TX side, ARP packets are not considered as dataplane packets. This feature requires configuration of signature. "dp core stats" command has been added Change-Id: I98e113cd02f36d540383d343a433592867ad86a9 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>

2018-09-14Improve l3fwd performanceXavier Simonart1-9/+3
JIRA: SAMPLEVNF-128 Improve performance of l3fwd use-case. L3fwd did not disable TX offload flags, which resulted in non-vector mode to be used in pmd in some cases like bare-metal. Note that in some cases such as virtio, vector mode was already used as OVS reports that it does not support TX-offload, hence TX-offload was already disabled on virtio. Using vector mode usually brings higher performance. Change-Id: I102b846d604a9cf28c6b7dae8bedbe918ccfcf6c Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2018-09-04Workaround DPDK net/virtio queue setup issuePatrice Buriez1-14/+14
JIRA: SAMPLEVNF-127 PROX was crashing in the VM with vector mode enabled and multiple OVS queues. This was not really a PROX bug, but a DPDK issue, which has been fixed by DPDK commit https://git.dpdk.org/dpdk/commit/?id=efc83a1e7fc3 This "net/virtio: fix queue setup consistency" is included in DPDK 17.11 and subsequent versions, and has been backported into: - DPDK 16.11.4: https://git.dpdk.org/dpdk-stable/commit/?h=16.11&id=516447a5056c - DPDK 17.08.1: https://git.dpdk.org/dpdk-stable/commit/?h=17.08&id=907fe4fc263e This means the fix is not included into any DPDK 17.02.x used by NSB. Fortunately, a simple workaround consists of calling rte_eth_tx_queue_setup() before rte_eth_rx_queue_setup(). This change implements this simple workaround, in order to make PROX work, even with unfixed DPDK versions.

2018-06-17Adding centos.json to be used with packer to generate a VM with PROXLuc Provoost16-84/+328
Based on a CentOS cloud image downloadable from the web, you can now use packer to create an image that has DPDK and PROX installed in the proper directories. The VM is also tuned for guest VNFs. A service is also created to deal with the proper isolated_cpu settings for tuned. The service will also make sure uio and igb_uio are loaded. The prox_user_data.sh is not needed any more and hence deleted. ctrl-c of runrapid.py will now also stop prox in all the VMs so a new test can be started.

2018-05-25Increase default mbuf size and code simplification/cleanupXavier Simonart18-98/+126
mbuf size was setup to achieve the best performance i.e. using the smallest mbuf and not segmenting packets. However this resulted in complex code, much dependent of the way the pmd are working e.g. a change(fix) in recent dpdk i40e implementation caused a 1782 (=1518+8+256) bytes mbuf to be too small to hold a 1518 bytes packets. Hence this change simplifies the mbuf size selection at the price of a potential decreases in performance - as more memory is now used. Except if jumbo frames are used, the mbuf size will now be the same for all modes. The packets will not be segmented except if jumbo frames are enabled. If jumbo frames are enabled, packets are by default segmented, except if the mbuf size is configured big enough in the config file.
