2021-08-20Fix ssh timeout issueLuc Provoost1-1/+1
Moving to paramiko for ssh introduced a bug: when starting PROX through ssh, a default timeout of 15 seconds was started. The timer is now disable since we need to run PROX as long as the test will take. Change-Id: I65162fff33beb6d30d2f5ee2b83f9bef7880ce4b Signed-off-by: Luc Provoost <luc.provoost@intel.com>

2021-05-12Fix latency buckets with multiple lat coresLuc Provoost3-66/+98
The bucket data of the last latency core was taken into account when collecting the latency stats. We are now adding the bucket data for all cores. Also changed the error reporting when PROX instance is breaking the pipe connection (e.g. when the dataplane network is overloaded).

2021-05-10Reinstate installation of igb_uioLuc Provoost2-1/+9
For good performance on some platforms, we need the igb_uio driver. With this change, the driver is compiled and insmod done during boot time. When running the rapid scripts, the devbind.sh script is sent to the instances (after replacing the string "MACADDRESS"). Make sure you uncomment the proper line to chose which driver you want to use. Change-Id: I69549400a97f29e06add6ab44515e96ffa9ce0e8 Signed-off-by: Luc Provoost <luc.provoost@intel.com>

2021-05-05New test case: gen versus swap via gatewayLuc Provoost4-10/+134
A new test was added: tests/basicrapid_gw.test. Traffic generated will now go to the reflector (swap instance) via the Gateway. The swap instance will also send the traffic back via the gateway. This use case is created to support GCP testing where the interfaces are defined with a /32 netmask, and hence all traffic is routed via the gateway.

2021-04-30Do not run after_boot.sh by defaultLuc Provoost1-10/+12
In the definition of the stack in openstack-rapid.yaml, we define a CloudConfig resource. after_boot.sh is called automatically by a service (check-prox-system-setup.service), after each boot. In this file, defined in the CloudConfig resource, you can put instructions needed for succesful operation and to fix certain issues in your environment. By default, this file should NOT be executed, hence we should not have this in the CloudConfig. Change the name back to after_boot.sh if you need to execute this code.

2021-04-28Default use of rapid_rsa_keyLuc Provoost6-23/+35
A secret and public key pair is available in the rapid directory: rapid_rsa_key and rapid_rsa_key.pub. createrapid.py is now modified to upload this key into OpenStack if the keypair does not already exist in OpenStack. Which keypair to use is now only defined in params_rapid.yaml. You can still define a key pair with a different name in params_rapid.yaml. If the secret and public key files are not available, a new keypair will be created and the secret key file will be saved. The name of the secret key file is the name as the OpenStack keypair name. The name of the public file is the same, with the pub extension. Change-Id: Ib8b5e4bf3a3d3138216698dc588a6908248220c0 Signed-off-by: Luc Provoost <luc.provoost@intel.com>
2021-04-22Fix error in sut throughput measurementLuc Provoost1-1/+1

2021-04-08cgnat test case addedLuc Provoost6-20/+346
A cgnat test can now be executed. This test needs 3 PROX instances. The first one, the generator needs to have an interface on the private dataplane network. The second instance, the cgnat needs to have it's first dataplane interface on the private network, while the second data plane needs to be on the public network. The third instance will be playing the role of internet server that the generator is connecting to. It will have one dataplane interface on the public network. This third instance will increase the packet size of the received packets by padding it with zeros and it will send the packets back to the cgnat mutliple times. How many times is defined by a multiplier in the cgnat.cfg file. In that cgnat file, we also define a range of IP addresses that will be used for the dynamic source IP NAT-ing. Make sure that the ports are allowed to accept other IP addresses than their own (e.g. allowed address pairs) and that the range of IP addresses is not overlapping with other machines in the public network.

2021-04-07Log ssh & scp related issues also on screenLuc Provoost1-10/+3
When scripts are doing an ssh or scp to the PROX instances, errors were sometimes hidden. E.g. when we try to upload a config file to the PROX instance that is already existing but owned by another user, we would not see the error on the screen. Note this will only happen if you build your own image. In case you use the pre-canned PROX images, this should not cause issues.

2021-03-15Fix the tuned optimizationsLuc Provoost8-30/+55
tuned-adm is now run through check_prox_system_setup.sh at the first system startup/reboot. This will result in the correct grub cmdline parameters. We are also coying the default rapid_rsa_key in the authorized_keys of the rapid user, which is now the default user to run the tests. Fixed also an issue in handle_mirror.c: using now ETYPE_IPv4. Changed deploycentostools.sh to reflect the changes done when building the image with disk-image-create.

Changed PROX and the python scripts so that the "lat all stats" command also returns the mis_ordered, extent and duplicate statistics. In order to make this work properly, we need now to also stop and restart the latency cores, every time we stop and start the generator cores, since the sequence numbers are reinitialised every time we start the generator core.

2021-01-27creation of tests and configs subdirectoriesLuc Provoost40-58/+136
All test files are now in the tests directory. All PROX config files moved to the configs directory. When specifying a test on the runrapid.py command line, you should now also mention the directory: e.g. --test tests/basicrapid.test In these test files, you need now to also include the configs subdirectory when specifying the prox configuration that needs to be used. The --map parameter has also changed. It can still take the file name of the map file, that specifies which PROX instance to use during a test. On top of that, you can now also specify a list of indices of the machines to be used during a test: e.g. --map [1,3].

2020-12-28Improved PROX cleanup when exitingLuc Provoost23-167/+232
Sending now a 'quit' command to PROX, so that the thread running PROX in an ssh session is now cleaned up correctly. Also fixed a problem with the logging when running the code more than once. We only create handlers now, when they do not yet exist. Updated the rapid version. Also added some more tests in the testcases.yaml for xtesting. At the end of a run, the PROX.log files are copied in the results directory. The success criterium for a test 'pass_threshold' has been removed from the test files and is to be controlled by the xtesting testcases.yaml file.

2020-11-13Fix for latency reporting and log file handlerLuc Provoost3-5/+5
The latency histogram dat did not contain samples collected during the first measurement of each step. The maximum latency did take the first step into account. As a result, you might see a test run with a maximum latency not showing up in the latency histogram data. This has been fixed by also including the data from the first measurement in the histogram data. In some cases, we also reported the wrong speed from the last unsuccessful step. This is now fixed and we do report the speed from the last successful step. In rapid_log.py, a fix was added to execute the rollover on the file handler of the log file in all cases. In some cases, the file handler with index 0 was not the file handler of the log file. Change-Id: I6c2b16c21dd0ee17d1d14e46c4c544e185324256 Signed-off-by: Luc Provoost <luc.provoost@intel.com>
2020-10-19Support dataplane subnet mask & latency histogramLuc Provoost16-36/+76
There is a new parameter in the config_file: dataplane_subnet_mask. This parameter is added to the dataplane IP addresses and is needed by the Linux stack to deal with some protocols (e.g. ARP). If not present, the default value of 24 will be used. In the end, this will make sure that IP addresses in the rapid.env file will have this mask, e.g. /24 If you use other tools than createrapid.py to create the rapid.env file, make sure to add the mask. This commit also introduces a change when exiting: we only copy the prox.log files from the different prox instances in case we expect a new prox.log file to be created in these instances. When using a valid format.yaml file, the tool will now also send the latency distribution data (histogram) to the URL. The tool is now also checking the value of bucket_size_exp: it needs to be 11 or more. Change-Id: I633cdc64ef687fdb6625be1e7482a5a371f83e93 Signed-off-by: Luc Provoost <luc.provoost@intel.com>
2020-09-29New PROX version, background traffic reportingLuc Provoost18-86/+89
deploycentostools.sh is now installing a recent PROX version. When using background traffic, the tool is also reporting the total traffic that was handled by the NFVi stack, including foreground & background traffic. The use of the prox_socket and prox_launch_exit was also broken in a previous release and is now fixed. When setting prox_socket to false for a PROX instance, we will not create a socket connection to control that PROX instance. Setting this option to false is not meaningful for the generator PROX instances since we would not be able to control the behavior of the PROX generator during the test. You could use the generator against another non-PROX instance and then set prox_socket to false for that non-PROX instance. Default is true. prox_launch_exit is used to start and stop the PROX program inside the instance. Default is true. This is useful in case you want to start PROX manually to be able to inspect the PROX UI, but at the same time, let the rapid scripts control the testing.

2020-09-16ramp generator traffic & prox.log copyLuc Provoost6-1/+75
A new parameter can be put in the *.test files so that the requested traffic is not generated at once, but slowly increasing up to the requested traffic. This is important for some SW switched that adapt and learn from the applied traffic. When suddenly applying a high traffic, the switch might not have enough time to learn and lose packets. Only after a period of time (up to 10 seconds?), the switch can cope with the traffic without packet loss. In order to get reproducible results in this case with low packet loss, please put the parameter ramp_step in the test section of the *.test file. The step is expressed in percentage of a 10Gb/s traffic. If the parameter is not present, the load will be immediately applied. When the runrapid.py script is now finished, it also copies the prox.log files from all the prox instances. In case of issues, please investigate this log file. When using background traffic, the tool will also print the average background traffic for each step in the DEBUG log. In this way, you can check that the background traffic is actually dealing with the same amount of traffic as the foreground. The tool is printing the packet reception rate of the background generators. A bug was also fixed regarding the latency percentile reporting. When using tests involving l2gen.cfg, the values of the percentile latency were wrong. Change-Id: Id3dd02ed5cab084414c717cf898b30e6980ddf31 Signed-off-by: Luc Provoost <luc.provoost@intel.com>

Hence we have a commit ID in deploycentostools.sh to make sure we have a version of PROX that we can work with. This change will now ensure we have a recent PROX version when we use deploycentostools.sh to build an image.

2020-08-06fix: IPV6 packet generation, packet loss reportingLuc Provoost10-28/+70
UDP and IP packet length and source UDP port and destination UDP port were wrongly set for IPv6 packets. In the *.test files, there is now an optional boolean field (ipv6) in the [TestParameters] section. When set to true, the generator will use the IPv6 packet layout to place the right values at the proper offset in the packet. If not present or set to false, the IPv4 layout will be used. Note also that packet size needs to be at least 84 bytes for IPV6 traffic since we need space for latency and other information in each packet. Packet loss ratio is now printed as a percentage of the total packets sent. Change-Id: I2136e87f3032348ae95b69052be7da8461c6303c Signed-off-by: Luc Provoost <luc.provoost@intel.com>

2020-07-05Adding vdev support and vfioLuc Provoost30-112/+179
Using vfio in stead of igb_uio. DPDK 2020.5 is NOT compiling the igb_uio driver by default any more. For the l3 mode, we are now using the new PROX vdev feature. This is achieved by adding the vdev parameter in the port section of the PROX config files. One of the advantages is that we can now ping a port managed by PROX: the requests will be forwarded by PROX to the LINUX stack, who will reply to the ping. A tap device is being created by PROX to support this feature. Installing old version of nasm since latest causes some issues. If not pushgateway is being used, it should be commented out in the config_file. vfio is now loaded by specifying the module in /etc/modules-load.d There is also an after_boot.sh script that will be run by check_prox_system_setup.sh, which can be used for further configuration of the instance after boot. There is now also a file created /opt/rapid/system_ready_for_rapid by the check_prox_system_setup.sh script. This file is created once all configuration is done.

2020-05-29Fix for container .env file and small updatesLuc Provoost17-104/+69
Since runrapid.py is now supporting more than 1 dataplane interface, we need to use a port index in the rapid.env file for the dataplane ports. In k8sdeployment.py, we only support 1 dataplane port, but we are writing dp_ip1 and dp_mac1 in the environment file. The copyright dates are also updated. Some references to VM have also been changed to instance. Change-Id: Ie1d036c13ef5d6f0aa1f35aa068a9760a1cfc2a9 Signed-off-by: Luc Provoost <luc.provoost@intel.com>
2020-05-28IPV6 testing & minor changes and fixesLuc Provoost20-92/+362
IPV6 test has been added. The generator will now generate IPV6 packets using NDP to resolve MAC addresses. The hex IP addresses in the inline definition of the packets in the cfg files is now calculated by a lua function called in parameters.lua. The hard-coded path /home/centos has been replaced by ~. An error in the speed calculations has been fixed. See the RapidTest class for details. The actual number of generated flows is now reported. If the requested number of flows is not a power of 2, the lowest power of 2 that is larger than the requested number of flows will be used and reported.

2020-05-15Support for imix packet sizesLuc Provoost18-41/+69
All packet size in the *.test files have been replaces with imix sizes. imix is now a list of packet sizes. If you want to run with only a pakcet size of 64, you need to specify a list containing only 1 size: [64]. You can also specify multiple imix values by specifying a list of list of sizes. The keyworkds in the test files are now imix & imixs. Change-Id: Iea47c0266b022133b7bbfc9a6811e3199ae41521 Signed-off-by: Luc Provoost <luc.provoost@intel.com>
2020-05-15createrapid.py is now using heat templates yamlLuc Provoost17-465/+523
yaml files have been added to the repo as an example. Please check the README explaining the output section reqs for this yaml file. There is also a new file (config_file): it also specifies which yaml files to use. multiple dataplane interfaces per VM can now be specified and will appear in the <STACK>.env file. An error in setting the packet size has been fixed (see set_udp_packet_size for packet size setting details) Change-Id: Ie89a4940521dac7dd3652acca477739abb9f5497 Signed-off-by: Luc Provoost <luc.provoost@intel.com>
