2020-05-29Added initial support for NDP (IPv6)Xavier Simonart1-13/+13
Following messages are now handled by PROX - router_solicitation - neighbour_solicitation - router_advertisement - neighbour_advertisement The following parameters are supported (through the PROX config file) - sub mode=ndp This will enable handling of router and neighbour solicitation and advertisement. - local ipv6=xxxx:xxxx:xxxxx:xxxx:xxxx:xxxx:xxxx:xxxx This will configure the local IPv6 address of the port. This parameter is optional. If not specified, the local IPv6 will be calculated from the EUI. - global ipv6=xxxx:xxxx:xxxxx:xxxx:xxxx:xxxx:xxxx:xxxx This will configure the global IPv6 address of the port. This parameter is optional. If not specified, the global IPv6 will be calculated from the EUI and the router prefix received from the router. - ipv6 router=yes This will cause the core to behave as an IPv6 router i.e. it will generate Router Advertisement messages This is only useful in back to back cases, when no real IPv6 router is present in the setup. - router prefix=xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx The router prefix usedin the router advertisement The prefix will be used by the node to build an IPv6 global address in cases none were configured. "Unsollicited NA" parameter has been added within the core/task section. If set to yes (Unsollicited NA=yes), then an unsollicited neighbour Advertisement is sent at startup A same core/task cannot support both l3 and ndp mode. Those messages will be generated or handled when submode is set to "ndp": - neighbour sollicitation - neighbour advertisement - router sollicitation - router advertisement An example configuration is provided: config/ipv6.cfg in which port 0 / core 1 plays the role of the generator and port 1 / core 2 plays the role of the swap.

2020-05-29Added support for IMIX through config and command lineXavier Simonart1-0/+42
In Prox configuration IMIX can be specified using the following syntax: imix=pkt_size,pkt_size... Up to 127 different pkt sizes can be specified. Through command line, the following syntax can be used imix core_id task_id pkt_size,pkt_size... Up to 127 packet sizes can be specified. When IMIX is enabled, PROX will loop through the list of packet sizes. PROX supports two different submodes to handle pcap files. In the 1st submode (default, no submode specified), timestamps from the pcap file are ignored. In this submode IMIX is supported as well and each packets in the pcap file will be generated with all IMIX sizes. In the second submode, called pcap in gen mode, packets are generated at the timestamp specified in the pcap file. This submode does not support IMIX.

2020-01-29Added command lat all statsXavier Simonart1-150/+157
lat all stats <core_id> <task_id> combines "lat stats" and "lat packets" within one command. This command returns: - One line in case the core_task parser fails. In that case the line will start with: "error: invalid syntax" - One set of lines for each core task: - if core/task is invalid, or not running lat mode, the line will contain (start with) "error...". this will be the only line for that core/task. - Otherwise the set of lines will be: - One line as returned by "lat stats". This line will be - One line starting with "error" in case of error, or - One line containing lat_min_usec, lat_max_usec, lat_avg_usec, tot_lat_min_usec, tot_lat_max_usec, last_tsc, rte_get_tsc_hz(), lcore_id, task_id - The return from lat packets i.e. - One line starting with "error" in case of error, or - 128 lines - one for each bucket - as returned by "lat packets" command This command is more useful then lat packets, as it contains the tsc - needed to see whether the sample is new or not.

2020-01-29Add Latency Distribution displayXavier Simonart1-2/+2
- Latency Distribution (i.e. histograms) has been added when latency is enabled. - Histograms are now compiled by default. - A bug has also been fixed, which was causing strange behavior in the histograms (due to bucket size being overwritten). - The default bucket size has been changed to "11" which means that the size of each bucket is now (1 cycle << 11) = 2048 cycles = 1 microsecond at 2GHz. It was (1 << (10 - 1)). As there are 128 latency buckets, it is not possible to show all of them on the display. Hence the latency buckets are displayed based on on the assumption that the minimum latency is usually relatively stable and that the maximum latency change more often. - The first empty buckets are not shown (i.e. buckets empty for all tasks) - If more than 15 buckets are non empty, then the buckets are combined, so that a maximum of 15 (bigger) buckets are shown - If less than 15 buckets are non empty, the following (empty) buckets are shown (this avoid seeing every x seconds some columns being added and removed).

2019-10-11Fix generation through pcap fileXavier Simonart1-4/+2
- When using "pcap file" argument in PROX config file in the gen mode (and no submode), packets were truncated to 8 bytes (and a warning printed) This has been fixed. - "Set value" command was checking whether offset was within first 1518 bytes unrespective to the mtu (e.g. jumbo packets). This has been fixed. - There was a limit of 64K packets loaded from a pcap file (which could be overwritten through PROX config). This limit has been removed - by default all packets from pcap are loaded - When pcap was loaded, memory was allocated to store the packet. However just enough memory was allocated, so that there was no way to change (increase) packet size through command line after that. Now memory is allocated to store up to mtu size - While "set value" command was acting on all packets, "pkt size" command was only changing the first packet. This has now been changed and both commands change all the packets. - A few other minor cleanups.

2019-06-14Support multiple tasks in "dp core stats" commandXavier Simonart1-9/+30
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 Buriez1-4/+5
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.

2018-10-28Add support for counting non dataplane related packetsXavier Simonart1-0/+34
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.

2018-01-25Merge "Integrate irq mode into PROX (support display and command line)"Deepak S1-1/+24
2018-01-24Fix extrapolation used in latency measurementsXavier Simonart1-4/+4
When doing latency measurements PROX takes into account the generation or reception of a bulk of packets. For instance, if PROX receives at time T 4 packets, it knows that the first packet was received by te NIC before T (the time to receive the other 3 packets, as they were received at maximum link speed). So the latency data is decreased by the minimum time to receive those 3 packets. For this PROX was using a default link speed of 10Gbps. This is wrong for 1Gbps and 40Gbps networks, and was causing for instance issues on 40 Gbps networks as extrapolating too much, resulting in either too low latencies or negative numbers (visible as very high latencies).

2018-01-16Integrate irq mode into PROX (support display and command line)Xavier Simonart1-1/+24
irq mode can be used to show how a core is interrupted by other tasks. This mode does not handle packets. It only loops reading tsc. When the difference between two consecutive calls to rdtsc() is high then it means the core was interrupted. This task implementes the display, so that we can see a histogram of interrupts as well as the maximum, per core. Command line is also supported, through "show irq buckets" (too show the intervals of each buckets, in micrcoseconds), and the stats command line (showing the number of items in each buckets and the max)..

2017-11-15Add support for nop mode with l3 submodeXavier Simonart1-4/+4
The l3 submode was not supported in nop mode, as the nop mode uses some specific nop thread (and not generic). When L3 is specified, the nop mode must use the generic thread. In addition the l3 submode is implemented differently than other submodes. It is not supported through task_init structures (i.e. each task does not have to explicitely tell that it supports l3 submode). But this prevented to run both a nop with no submode and a nop with a l3 submode. Note that nop with l3 is usually not very useful - it handles arp (requests and response) but as nop, it does not swap IP addresses. So with a real switch, the packets transmitted will be received back... and l3 mode is usually mainly usefull when using a switch. However, there is at least one nop mode where l3 submode makes sense: when the nop does not transmit. In such cases, for instace used in conjunction with a gen l3, the nop receives all packets and forward the arp requests and responses to the master for handling.
