2019-10-11Fix generation through pcap fileXavier Simonart4-25/+26
- 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.

2019-10-08Fix setting mac address through [port] sectionXavier Simonart1-0/+3
MAC address can be configured through the [port] section. However this had only some effect on packets being transmitted. For instance it was used to set the src mac address by the generator. It had no effect on packets reception: when not in promiscuous mode only the packets with the MAC originally set by the HW were received. Now, when not in promiscuous mode, only packets with MAC as defined in [port] section will be received.

2019-09-04Add heartbeat support (stop all cores in case of TCP socket issues)Xavier Simonart5-0/+37
"heartbeat timeout" (in second) can be specified as a global parameter in PROX config file. If set, a timer is started when the first command is received from the TCP socket. This timer is reset at each commands received through the TCP socket. If the timer expires, then - all cores are stopped - the TCP socket is closed, causing an error at client side. This feature helps in case a script starts PROX and the traffic generated through PROX causes issues to the control plane.

2019-07-04Fix keyboard related issues on Ubuntu 18.04Xavier Simonart2-1/+34
On Ubuntu 18.04, the keyboard was not properly handled in PROX For instance, many keys pressed were silently discarded. The issue is related to a change in histedit/libedit version. Recent libedit have (silently) changed the prototype of the get_char function passed in el_set(el, EL_GETCFN, get_char), with some input parameters changing from char to wchar_t. As PROX used the old prototype (char based), this resulted in some uninitialized field (= garbage) in the wchar_t, causing libedit to discard the character. PROX now uses different get_char prototypes, depending of the libedit version being used. If PROX was already compiled and a the OS is updated (e.g. from Ubuntu 16.04 to Ubuntu 18.04), this will require a 'make clean'.

2019-07-01Cosmetic change when printing warningsProvoost1-1/+3
Warnings can be printed in the following cases: - When not enough packets are taken into account for measuring packet latency accuracy. - When there us a potential network throughput issue, meaning the generator is generating more packets than the the NIC can handle - When the generator cannot generate the requested load If there are no warnings for a certain measurement, nothing gets printed, suppressing an empty line Change-Id: Iee07c12142e28dcc0ac406bfed7626731ab08f98 Signed-off-by: Luc Provoost <luc.provoost@intel.com>
2019-06-30Multiple changes for June releaseLuc Provoost25-713/+861
- Change inittest in warmuptest. This has now a warmuptime, warmupspeed, packet size and flow size. - Change in centos.json. This will now also copy deploycentostools.sh during image building so that it can be used to re-compile prox in the VM by typing "./deploycentostools.sh compile" - runrapid.py parameters needing a file name, need to be complete file names: no extensions will be added any more by the scripts. - Changes in createrapid.py to handel the openstack CLI output in a simpler way. - The management interface of the VMs can now also be an SRIOV interface. We have now an extra optional parameter in the VM sections of the rapiVMs.vms file: SRIOV_mgmt_port - Changed the name of some sections and keys in the environment file since runrapid.py will not always communicate to OpenStack VMs. This could be containers or any other (virtual) machine. - The previous MachineMap.cfg has been renamed to machine.map - A new test has been added: monitorswap is just showing the statistics of a swap (virtual) machine, without generating any packets. This is useful in situations where an external tester is used. - Latency and core statistics can now be measured even if there are multiple PROX cores and tasks running. A new parameter has been added in the test files with following default value: tasks=[0]. During the collection of statistics, all tasks in this list will be queried. It is ok to have a non-existing task in such a query since it will be ignored. - A --screenlog parameter was added for runrapid.py allowing for more detailed output on the screen during debugging. No need to check the log file. - Previous tests to run multiple packet size with a given flow size and to run multiple flow size, with a given packet size are now combined by specifiying 2 lists: packetsizes & flows - The screen output of this test has also been reworked with more meaningful column names and the test result is now in the field "core received". This allows also for faster termination of the test: When the all packets sent by Gen NIC are received by the cores within the thresholds for packet loss and latency, the test is now stopped, even we were requesting more packets to be sent.

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.

2019-03-08Fix 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>

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>
