Main objective of this series is to convert the gro.sh and toeplitz.sh tests to be "NIPA-compatible" - meaning make use of the Python env, which lets us run the tests against either netdevsim or a real device.
The tests seem to have been written with a different flow in mind. Namely they source different bash "setup" scripts depending on arguments passed to the test. While I have nothing against the use of bash and the overall architecture - the existing code needs quite a bit of work (don't assume MAC/IP addresses, support remote endpoint over SSH). If I'm the one fixing it, I'd rather convert them to our "simplistic" Python. This series rewrites the tests in Python while addressing their shortcomings. The functionality of running the test over loopback on a real device is retained but with a different method of invocation (see the last patch). Once again we are dealing with a script which run over a variety of protocols (combination of [ipv4, ipv6, ipip] x [tcp, udp]). The first 4 patches add support for test variants to our scripts. We use the term "variant" in the same sense as the C kselftest_harness.h - variant is just a set of static input arguments. Note that neither GRO nor the Toeplitz test fully passes for me on any HW I have access to. But this is unrelated to the conversion. This series is not making any real functional changes to the tests, it is limited to improving the "test harness" scripts. v2: [patch 5] fix accidental modification of gitignore [patch 8] fix typo in "compared" [patch 9] fix typo I -> It [patch 10] fix typoe configure -> configured v1: https://lore.kernel.org/[email protected] Jakub Kicinski (12): selftests: net: py: coding style improvements selftests: net: py: extract the case generation logic selftests: net: py: add test variants selftests: drv-net: xdp: use variants for qstat tests selftests: net: relocate gro and toeplitz tests to drivers/net selftests: net: py: support ksft ready without wait selftests: net: py: read ip link info about remote dev netdevsim: pass packets thru GRO on Rx selftests: drv-net: add a Python version of the GRO test selftests: drv-net: hw: convert the Toeplitz test to Python netdevsim: add loopback support selftests: net: remove old setup_* scripts tools/testing/selftests/drivers/net/Makefile | 2 + .../testing/selftests/drivers/net/hw/Makefile | 6 +- tools/testing/selftests/net/Makefile | 7 - tools/testing/selftests/net/lib/Makefile | 1 + drivers/net/netdevsim/netdev.c | 26 ++- .../testing/selftests/{ => drivers}/net/gro.c | 5 +- .../{net => drivers/net/hw}/toeplitz.c | 7 +- .../testing/selftests/drivers/net/.gitignore | 1 + tools/testing/selftests/drivers/net/gro.py | 161 ++++++++++++++ .../selftests/drivers/net/hw/.gitignore | 1 + .../drivers/net/hw/lib/py/__init__.py | 4 +- .../selftests/drivers/net/hw/toeplitz.py | 208 ++++++++++++++++++ .../selftests/drivers/net/lib/py/__init__.py | 4 +- .../selftests/drivers/net/lib/py/env.py | 2 + tools/testing/selftests/drivers/net/xdp.py | 42 ++-- tools/testing/selftests/net/.gitignore | 2 - tools/testing/selftests/net/gro.sh | 105 --------- .../selftests/net/lib/ksft_setup_loopback.sh | 111 ++++++++++ .../testing/selftests/net/lib/py/__init__.py | 5 +- tools/testing/selftests/net/lib/py/ksft.py | 93 ++++++-- tools/testing/selftests/net/lib/py/nsim.py | 2 +- tools/testing/selftests/net/lib/py/utils.py | 20 +- tools/testing/selftests/net/setup_loopback.sh | 120 ---------- tools/testing/selftests/net/setup_veth.sh | 45 ---- tools/testing/selftests/net/toeplitz.sh | 199 ----------------- .../testing/selftests/net/toeplitz_client.sh | 28 --- 26 files changed, 630 insertions(+), 577 deletions(-) rename tools/testing/selftests/{ => drivers}/net/gro.c (99%) rename tools/testing/selftests/{net => drivers/net/hw}/toeplitz.c (99%) create mode 100755 tools/testing/selftests/drivers/net/gro.py create mode 100755 tools/testing/selftests/drivers/net/hw/toeplitz.py delete mode 100755 tools/testing/selftests/net/gro.sh create mode 100755 tools/testing/selftests/net/lib/ksft_setup_loopback.sh delete mode 100644 tools/testing/selftests/net/setup_loopback.sh delete mode 100644 tools/testing/selftests/net/setup_veth.sh delete mode 100755 tools/testing/selftests/net/toeplitz.sh delete mode 100755 tools/testing/selftests/net/toeplitz_client.sh -- 2.51.1
