Hi! Implement support for tests which require access to a remote system / endpoint which can generate traffic. This series concludes the "groundwork" for upstream driver tests. I wanted to support the three models which came up in discussions: - SW testing with netdevsim - "local" testing with two ports on the same system in a loopback - "remote" testing via SSH so there is a tiny bit of an abstraction which wraps up how "remote" commands are executed. Otherwise hopefully there's nothing surprising. I'm only adding a ping test. I had a bigger one written but I was worried we'll get into discussing the details of the test itself and how I chose to hack up netdevsim, instead of the test infra... So that test will be a follow up :) v3: - first two patches are new - make Remote::cmd() return Popen() object (patch 3) - always operate on absolute paths (patch 3) - last two patches are new v2: https://lore.kernel.org/all/20240416004556.1618804-1-kuba@xxxxxxxxxx - rename endpoint -> remote - use 2001:db8:: v6 prefix - add a note about persistent SSH connections - add the kernel config v1: https://lore.kernel.org/all/20240412233705.1066444-1-kuba@xxxxxxxxxx Jakub Kicinski (8): selftests: net: fix counting totals when some checks fail selftests: net: set the exit code correctly in Python tests selftests: drv-net: define endpoint structures selftests: drv-net: factor out parsing of the env selftests: drv-net: construct environment for running tests which require an endpoint selftests: drv-net: add a trivial ping test selftests: net: support matching cases by name prefix selftests: drv-net: add a TCP ping test case (and useful helpers) tools/testing/selftests/drivers/net/Makefile | 5 +- .../testing/selftests/drivers/net/README.rst | 33 ++++ .../selftests/drivers/net/lib/py/__init__.py | 1 + .../selftests/drivers/net/lib/py/env.py | 141 +++++++++++++++--- .../selftests/drivers/net/lib/py/remote.py | 15 ++ .../drivers/net/lib/py/remote_netns.py | 21 +++ .../drivers/net/lib/py/remote_ssh.py | 39 +++++ tools/testing/selftests/drivers/net/ping.py | 52 +++++++ tools/testing/selftests/drivers/net/stats.py | 4 +- .../testing/selftests/net/lib/py/__init__.py | 1 + tools/testing/selftests/net/lib/py/ksft.py | 25 +++- tools/testing/selftests/net/lib/py/netns.py | 31 ++++ tools/testing/selftests/net/lib/py/utils.py | 50 ++++++- tools/testing/selftests/net/nl_netdev.py | 4 +- 14 files changed, 391 insertions(+), 31 deletions(-) create mode 100644 tools/testing/selftests/drivers/net/lib/py/remote.py create mode 100644 tools/testing/selftests/drivers/net/lib/py/remote_netns.py create mode 100644 tools/testing/selftests/drivers/net/lib/py/remote_ssh.py create mode 100755 tools/testing/selftests/drivers/net/ping.py create mode 100644 tools/testing/selftests/net/lib/py/netns.py -- 2.44.0
