passt: Relicense to GPL 2.0, or any later version 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. Jones, Chris Kuhn, Florian Weimer, Giuseppe Scrivano, Stefan Hajnoczi, and Vasiliy Ulyanov. Signed-off-by: Stefano Brivio <sbrivio@redhat.com>

test/perf: Switch performance test duration to 10 seconds instead of 30 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: Disable periodic throughput reports to avoid vhost hang 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: Start iperf3 server less often Currently we start both the iperf3 server(s) and client(s) afresh each time we want to make a bandwidth measurement. That's not really necessary as usually a whole batch of bandwidth measurements can use the same server. Split up the iperf3 directive into 3 directives: iperf3s to start the server, iperf3 to make a measurement and iperf3k to kill the server, so that we can start the server less often. This - and more importantly, the reduced number of waits for the server to be ready - reduces runtime of the performance tests on my laptop by about 4m (out of ~28minutes). For now we still restart the server between IPv4 and IPv6 tests. That's because in some cases the latency measurements we make in between use the same ports.

test/perf: Start iperf3 server less often Currently we start both the iperf3 server(s) and client(s) afresh each time we want to make a bandwidth measurement. That's not really necessary as usually a whole batch of bandwidth measurements can use the same server. Split up the iperf3 directive into 3 directives: iperf3s to start the server, iperf3 to make a measurement and iperf3k to kill the server, so that we can start the server less often. This - and more importantly, the reduced number of waits for the server to be ready - reduces runtime of the performance tests on my laptop by about 4m (out of ~28minutes). For now we still restart the server between IPv4 and IPv6 tests. That's because in some cases the latency measurements we make in between use the same ports.

Don't abbreviate ip(8) arguments in examples and tests 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.

test/perf/pasta_udp: Add host to namespace cases for traffic via tap 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 traffic being routed via the tap interface (as opposed to the loopback interface). We now clarified that's actually the case. Use same values and thresholds as the tests for loopback traffic, as throughput figures currently indicate there isn't much difference.

test/perf: Start iperf3 server less often Currently we start both the iperf3 server(s) and client(s) afresh each time we want to make a bandwidth measurement. That's not really necessary as usually a whole batch of bandwidth measurements can use the same server. Split up the iperf3 directive into 3 directives: iperf3s to start the server, iperf3 to make a measurement and iperf3k to kill the server, so that we can start the server less often. This - and more importantly, the reduced number of waits for the server to be ready - reduces runtime of the performance tests on my laptop by about 4m (out of ~28minutes). For now we still restart the server between IPv4 and IPv6 tests. That's because in some cases the latency measurements we make in between use the same ports.
