test: Fedora 32-35 have moved to the archives

2023-02-14T16:25:20+00:00

Fedora 32-35 are now old enough that they're not on all mirrors.  Fetch
them from the archive server instead.

The current debian cloud images no longer include ppc64.  Change to using
the latest snapshot which does include ppc64.

test/pasta_options: Ignore failures on shell 'exit'

2023-02-12T23:05:48+00:00

On shell 'exit' commands, running shells from pasta, we might get:

  Cannot set tty process group (No such process)

as some TTY devices might be unaccessible. This is harmless, but
after commit "pasta: propagate exit code from child command", we'll
get test failures there, at least with dash.

Ignore those explicitly with a ugly workaround: we can't simply do
something like:

	exit || :

because the failure is reported by the shell itself once it exits,
regardless of the command evaluation.

test/perf/pasta_tcp: Add host to namespace cases for traffic via tap

2023-01-05T14:08:11+00:00

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/pasta_udp: Add host to namespace cases for traffic via tap

2023-01-05T14:07:54+00:00

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/lib/test: Clean up iperf3 JSON files before starting the server

2022-11-16T14:11:25+00:00

...instead of doing it after the test. Now that we have pre-built
guest images, we might also have old JSON files from previous,
interrupted test runs.

test/memory/passt: Change passt.avx2 path to /bin in test itself

2022-11-04T11:04:32+00:00

Now that we install the binary in /bin, and we have a link from
/usr/bin, change the path in the test itself as well. Otherwise
it works with bash but not with dash for some reason.

test/perf: Finally drop workaround for virtio_net TX stall

2022-11-04T11:04:32+00:00

Now that we require 13c6be96618c ("net: stream: add unix socket")
in qemu to run the tests, we can also assume that commit df8d07081718
("virtio-net: fix bottom-half packet TX on asynchronous completion")
is present, as it was merged before that one.

This fixes the issue we attempted to work around in passt TCP and
UDP performance tests: finally drop that stuff.

test: Switch to qemu -netdev stream option instead of using qrap

2022-11-04T11:04:32+00:00

qemu commit 13c6be96618c ("net: stream: add unix socket") introduces
support for native AF_UNIX support, finally making qrap useless.

We can't quite drop that yet until a qemu release includes it, and
then we'll need to wait a while for users to switch anyway, but at
least for tests, we can use that support.

test: Wait for network before starting passt in two_guests setup

2022-11-04T11:04:32+00:00

As pasta now configures that target network namespace with
--config-net, we need to wait for addresses and routes to be actually
present. Just sending netlink messages doesn't mean this is done
synchronously.

A more elegant alternative, which probably makes sense regardless of
this test setup, would be to query, from pasta, addresses and routes
we added, and wait until they're there, before proceeding.
