2019-04-12Improved image building & new PROXLuc Provoost25-551/+764
Bug fixes for the script for building an image via the packer tool. This also installs a newer version of PROX with some bug fixes in PROX. The *.test files have been simplified. Also introduced a new file MachineMap.cfg to map test machines on actual VMs. Change-Id: I69445327ef0a907bc8c1566aaa60c733418c541e Signed-off-by: Luc Provoost <>
2019-03-08Fix PROX generator latencyXavier Simonart2-4/+23
When PROX fails to transmit packets (e.g. because switch or NIC is overloaded) some cleanup needs to be done related to packet id and latency. In addition, in some casesi, the clock estimate is slighly over-estimated which might result, in rare cases, in negative (hence very high) latencies, due to the extrapolation of timestamps. This has been workarounded bydecreasing the extrapolation, tolerating up to 1% clock estimate error Change-Id: I1ba17dfe0d5e2f9f9167f4f087ed0d96da1293c2 Signed-off-by: Xavier Simonart <>

2019-03-06PROX generator: performance optimization (2/4)Xavier Simonart8-162/+101
Improve PROX generator performance by pre-calculating bytes_to_tsc. This improvement is only implemented for non-pcap generator, where only few different packet sizes are usually generated. This change might have a negative performance impact in some cases, if many different packet sizes are generated, resulting in higher memory usage. This is the case for instance if random is applied to packet size. In addition, simplified the rx path, receiving now only MAX_PKT_BURST packets per handle loop. Before we were trying to empty the NIC looping on RX packets, ending up with many rx packets per handle loop. This was used to determine an lower bound for the time the packet was received. We now set the lower bound when less than MAX_PKT_BURST has been received. Change-Id: I1ce813d7e4ac1577ea412c590add5d6f94b36ec7 Signed-off-by: Xavier Simonart <>

2019-02-20Use link speed from device capability instead of negotiated speedaXavier Simonart4-13/+94
JIRA: SAMPLEVNF-151 link speed is used in gen and lat latency extrapolations. Using a link_speed value lower than the actual link speed might result in errors (e.g. negative latencies). Negotiated link speed might be reported slowly (as reported through irq) Hence it is better to use the device capability link speed. In addition, this remove the check for link speed changes in fastpath. Change-Id: I0f475fe5e139b046012de6cd0b710e4390735078 Signed-off-by: Xavier Simonart <>

2019-01-30Fix memory leak in L3 submodeXavier Simonart2-1/+3
In L3 submodes, there were two memory leaks - when a L3 core was restarted, causing around 2MB leak and a potential issue after 256 start/stop - a potential mbuf leak when handling arp replies Those have been fixed Change-Id: I348478fa5967936297850432e93667e12b0adac4 Signed-off-by: Xavier Simonart <>
2019-01-28Add support for configurable arp timers in L3 modeXavier Simonart4-7/+26
L3 mode supports two timers: - arp_update_time, defaulted to 1 second, which makes PROX to send arp request every second for active flows - arp_timeout, previously defaulted to 30 seconds, which makes PROX consider a MAC address as invalid if no arp_reply was received within those 30 seconds. Those timers values were hardcoded. They can now be configured through the configuration file (within the core section), using resp. "arp update time" and "arp timeout" keywords. Unit is milli seconds. The default becomes respectively 1 second and 2 weeks. Change-Id: I35e46e97df32ca44c2cdfae85a20ee015de5d6e1 Signed-off-by: Xavier Simonart <>

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 <>
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. Change-Id: I45cef19fed09bb4f86644d56d689a0959a9038db Signed-off-by: Xavier Simonart <>

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. Change-Id: Icb6083a8cdf88789553ad23c32ca12d6b7ba7f08 Signed-off-by: Xavier Simonart <>
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.

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 <>

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 <>

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 <>
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 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: - DPDK 17.08.1: 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. Change-Id: I818e9bb812babe023c6b7225c8b9769a359d9bec Signed-off-by: Patrice Buriez <>

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.
