io_uring/zcrx: add selftestAdd a selftest for io_uring zero copy Rx. This test cannot run locallyand requires a remote host to be configured in net.config. The remotehost must have hardware support for zero copy Rx as listed in thedocumentation page. The test will restore the NIC config back to beforethe test and is idempotent.liburing is required to compile the test and be installed on the remotehost running the test.Signed-off-by: David Wei Acked-by: Jakub Kicinski Link: https://lore.kernel.org/r/20250215000947.789731-12-dw@davidwei.ukSigned-off-by: Jens Axboe List of files: /linux-6.15/tools/testing/selftests/drivers/net/hw/Makefile

1d0dc857 - selftests: drv-net: add checksum tests

Tue, 07 May 2024 15:40:58 +0000

selftests: drv-net: add checksum testsRun tools/testing/selftest/net/csum.c as part of drv-net.This binary covers multiple scenarios, based on arguments given,for both IPv4 and IPv6:- Accept UDP correct checksum- Detect UDP invalid checksum- Accept TCP correct checksum- Detect TCP invalid checksum- Transmit UDP: basic checksum offload- Transmit UDP: zero checksum conversionThe test direction is reversed between receive and transmit tests, sothat the NIC under test is always the local machine.In total this adds up to 12 testcases, with more to follow. Forconciseness, I replaced individual functions with a function factory.Also detect hardware offload feature availability using Ethtoolnetlink and skip tests when either feature is off. This need may becommon for offload feature tests and eventually deserving of a thinwrapper in lib.py.Missing are the PF_PACKET based send tests ('-P'). These usevirtio_net_hdr to program hardware checksum offload. Which requireslooking up the local MAC address and (harder) the MAC of the next hop.I'll have to give it some though how to do that robustly and wherethat code would belong.Tested: make -C tools/testing/selftests/ \ TARGETS="drivers/net drivers/net/hw" \ install INSTALL_PATH=/tmp/ksft cd /tmp/ksft sudo NETIF=ens4 REMOTE_TYPE=ssh \ REMOTE_ARGS="root@10.40.0.2" \ LOCAL_V4="10.40.0.1" \ REMOTE_V4="10.40.0.2" \ ./run_kselftest.sh -t drivers/net/hw:csum.pySigned-off-by: Willem de Bruijn Link: https://lore.kernel.org/r/20240507154216.501111-1-willemdebruijn.kernel@gmail.comSigned-off-by: Jakub Kicinski List of files: /linux-6.15/tools/testing/selftests/drivers/net/hw/Makefile

40d269c0 - selftests: forwarding: Move several selftests

Tue, 26 Mar 2024 16:54:32 +0000

selftests: forwarding: Move several selftestsThe tests in net/forwarding are generally expected to be HW-independent.There are however several tests that, while not depending on any HW inparticular, nevertheless depend on being used on HW interfaces. Placingthese selftests to net/forwarding is confusing, because the selftest willjust report it can't be run on veth pairs. At the same time, placing themto a particular driver's selftests subdirectory would be wrong.Instead, add a new directory, drivers/net/hw, where these generic but HWindependent selftests should be placed. Move over several such testsincluding one helper library.Since typically these tests will not be expected to run, omit the directorydrivers/net/hw from the TARGETS list in selftests/Makefile. Retain aMakefile in the new directory itself, so that a user can make -C into thatdirectory and act on those tests explicitly.Cc: Roger Quadros Cc: Tobias Waldekranz Cc: Danielle Ratson Cc: Davide Caratti Cc: Johannes Nixdorf Suggested-by: Jakub Kicinski Signed-off-by: Petr Machata Link: https://lore.kernel.org/r/e11dae1f62703059e9fc2240004288ac7cc15756.1711464583.git.petrm@nvidia.comSigned-off-by: Jakub Kicinski List of files: /linux-6.15/tools/testing/selftests/drivers/net/hw/Makefile
