* test/perf: Remove stale iperf3c/iperf3s directivesDavid Gibson2023-11-071-2/+1
| | | | | | | | | | Some older revisions used separate iperf3c and iperf3s test directives to invoke the iperf3 client and server. Those were combined into a single iperf3 directive some time ago, but a couple of places still have the old syntax.

* passt: Relicense to GPL 2.0, or any later versionStefano Brivio2023-04-061-1/+1
| | | | | | | | | | | | | | | | | | | In practical terms, passt doesn't benefit from the additional protection offered by the AGPL over the GPL, because it's not suitable to be executed over a computer network. Further, restricting the distribution under the version 3 of the GPL wouldn't provide any practical advantage either, as long as the passt codebase is concerned, and might cause unnecessary compatibility dilemmas. Change licensing terms to the GNU General Public License Version 2, or any later version, with written permission from all current and past contributors, namely: myself, David Gibson, Laine Stump, Andrea Bolognani, Paul Holzinger, Richard W.M.

* test/perf/pasta_tcp: Add host to namespace cases for traffic via tapStefano Brivio2023-01-051-0/+57
| | | | | | | | | | Similarly to UDP cases, these were missing as it wasn't clear, when the other tests were introduced, if using the global address of a namespace, from the host, should have resulted in connections being routed via the tap interface.

* test/perf: Disable periodic throughput reports to avoid vhost hangStefano Brivio2022-09-221-1/+1
| | | | | | | | | | | | | | | | | | It appears that if we run throughput tests with one-second periodic reports, the sending side of the vhost channel used for SSH-based command dispatch occasionally stops working altogether. I haven't investigated this further, all I see is that output is truncated at some point, and doesn't resume. If we use gzip compression (ssh -C) this happens less frequently, but it still happens, seemingly indicating the issue is probably related to vhost itself. Disable periodic reports in iperf3 clients. The -i options were actually redundant, so remove them from both test files as well as from test_iperf3(). Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
* test/perf: Switch performance test duration to 10 seconds instead of 30Stefano Brivio2022-09-221-1/+1
| | | | | | | | | It looks like the workaround for the virtio_net TX hang issue is working less reliably with the new command dispatch mechanism, I'm not sure why. Switch to 10 seconds, at least for the moment. Signed-off-by: Stefano Brivio <sbrivio@redhat.com> Reviewed-by: David Gibson <david@gibson.dropbear.id.au>

* test/perf: Check for /sbin/sysctl with which(1), not simply sysctlStefano Brivio2022-09-221-1/+1
| | | | | | | | | | Otherwise, we're depending on having /sbin in $PATH. For some reason I didn't completely grasp, with the new command dispatch mechanism that's not the case anymore, even if I have /sbin in $PATH in the parent shell.

* test: Rewrite test_iperf3David Gibson2022-09-071-1/+1
| | | | | | | | | | | | | | | test_iperf3() is a pretty inscrutable mess of nested background processes. It has a number of ugly sleeps needed to wait for things to complete. Rewrite it to be cleaner: * Use the construct (a & b & wait) to run 'a' and 'b' in parallel, but then wait for them both to complete before continuing * This allows us to wait for both the server and client to finish, rather than sleeping * Use jq to do all the math we need to get the final result, rather than jq followed by some complicated 'bc' mangling Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* test: Parameterize run time for throughput performance testsDavid Gibson2022-09-071-20/+22
| | | | | | | | | | | | Currently all the throughput tests are run for 30s. This is reflected in both the actual parameters given to the iperf commands, but also in the matching sleeps in test_iperf3. Allow this to be adjusted more easily with a new parameter to test_iperf3.

* test: Combine iperf3c and iperf3s into a single DSL commandDavid Gibson2022-09-071-34/+17
| | | | | | | | | | | | | | | | | These two commands in the DSL to run an iperf client and server are always used together, and some of the parameters must match between them. The iperf3s must also be run more or less immediately after iperf3c, since iperf3c will run a client in the background after a sleep and requires a server to be running before it will work. A bunch of things can be made cleaner if we make a single DSL command that runs both sides of the test. For now make the combined command work exactly like the two commands together did, warts and all. This does lose the ability for the DSL scripts to give additional options to the iperf3 server, but we weren't using that anyway. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* tests: Explicitly list test files in test/run, remove "onlyfor" supportDavid Gibson2022-07-141-1/+0
| | | | | | | | | | | | | | | | | Currently test/run uses wildcards to run all of the tests in a directory. However, that wildcard list is filtered down by the "onlyfor" directives in the test files... usually to a single file. Therefore, just explicitly list the files we *really* want to run for this test mode. This makes it easier to see at the top level what tests will be executed, and to change that list temporarily while debugging specific failures. This means the "onlyfor" directive no longer has any purpose, and we can remove it. "onlyfor" was also the only used of the $MODE variable, so we can remove that too.

* Don't abbreviate ip(8) arguments in examples and testsDavid Gibson2022-06-151-3/+3
| | | | | | | | ip(8)'s ability to take abbreviated arguments (e.g. "li sh" instead of "link show") is very handy when using it interactively, but it doesn't make for very readable scripts and examples when shown that way. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
