2019-06-27Fix "code nested too deep error" introduced by commit 843ca042Xavier Simonart1-44/+46

2019-06-14Increase window size for latency accuracyXavier Simonart3-15/+19
Accuracy of latency is obtained by writing TX accuracy for packet N in a later packet i.e. packet N + WINDOW. If this window is too small, packet N + WINDOW (conveying accuracy for packet N) might arrive before packet N, resulting in no accuracy for packet N. This change increases this window from 64 to 8K packets. This change should result in a higher number of packets used for latency measurements when packets are reordered. This change might have a performance impact as it uses more memory.

2019-06-14Support multiple tasks in "dp core stats" commandXavier Simonart2-10/+31
The "dp core stats" command supported, as other commands, multiple cores but not multiple tasks. It now supports both (e.g. dp core stats 1-2 0-1). This is necessary so that users can collect all statistics from PROX in one command line. It will return similar information on the screen or through the socket: - if the syntax is wrong (e.g. missing task, too many cores or tasks, ...) => an error message is printed on the screen, and the single error line "error: invalid syntax" is returned through the socket - if the syntax is correct => one line is printed or returned for each core/task pair => if the core/task pair is invalid, the line reports an error => otherwise, the line provides dataplane statistics for the core/task pair, with the core_id and task_id added, either at the end of the line returned through the socket, or at the beginning of the line printed on the screen. This means a change in behaviour when using the socket: before, when an error happened (e.g. bad task), then nothing was returned which made it difficult for the script to catch the syntax error. Similar behaviour could/should be implemented for other commands. However, care must be taken as some scripts like NSB might count the number of lines within the output, or the number of items within the line. This should not be an issue for dp core stats as NSB does not use it, and other PROX scripts do not count the number of items and will be adjusted to count the number of lines.

2019-06-14Add "total TX fail" count to "dp core stats" command outputPatrice Buriez3-4/+11
Warning: This change breaks backward-compatibility of PROX socket scripting API, because the "total TX fail" count is reported before the "last TSC" field. As a result, PROX scripts that make use of the "dp core stats" command, such as the core_stats() method in helper-scripts/openstackrapid/prox_ctrl.py, MUST be reworked to correctly parse the returned set of fields.

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 <xavier.simonart@intel.com>

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 <xavier.simonart@intel.com>

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 <xavier.simonart@intel.com>

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 <xavier.simonart@intel.com>

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>

2018-12-13Add 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.

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.

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>
