selftests: drv-net: add a Python version of the GRO test

2025-11-21T02:19:30+00:00

Rewrite the existing gro.sh test in Python. The conversion not exact, the changes are related to integrating the test with our "remote endpoint" paradigm. The test now reads the IP addresses from the user config. It resolves the MAC address (including running over Layer 3 networks).

selftests: net: relocate gro and toeplitz tests to drivers/net

2025-11-21T02:19:29+00:00

The GRO test can run on a real device or a veth. The Toeplitz hash test can only run on a real device. Move them from net/ to drivers/net/ and drivers/net/hw/ respectively. There are two scripts which set up the environment for these tests setup_loopback.sh and setup_veth.sh. Move those scripts to net/lib. The paths to the setup files are a little ugly but they will be deleted shortly. toeplitz_client.sh is not a test in itself, but rather a helper to send traffic, so add it to TEST_FILES rather than TEST_PROGS.

selftest: netcons: create a torture test

2025-11-11T02:34:44+00:00

Create a netconsole test that puts a lot of pressure on the netconsole list manipulation. Do it by creating dynamic targets and deleting targets while messages are being sent. Also put interface down while the messages are being sent, as creating parallel targets. The code launches three background jobs on distinct schedules: * Toggle netcons target every 30 iterations * create and delete random_target every 50 iterations * toggle iface every 70 iterations This creates multiple concurrency sources that interact with netconsole states. This is good practice to simulate stress, and exercise netpoll and netconsole locks.

selftests: drv-net: replace the nsim ring test with a drv-net one

2025-10-31T00:32:18+00:00

We are trying to move away from netdevsim-only tests and towards tests which can be run both against netdevsim and real drivers. Replace the simple bash script we have for checking ethtool -g/-G on netdevsim with a Python test tweaking those params as well as channel count. The new test is not exactly equivalent to the netdevsim one, but real drivers don't often support random ring sizes, let alone modifying max values via debugfs.

selftests: net: unify the Makefile formats

2025-10-06T20:14:06+00:00

We get a significant number of conflicts between net and net-next because of selftests Makefile changes. People tend to append new test cases at the end of the Makefile when there's no clear sort order. Sort all networking selftests Makefiles, use the following format: VAR_NAME := \ entry1 \ entry2 \ entry3 \ # end of VAR_NAME Some Makefiles are already pretty close to this.

selftests: drv-net: add PSP responder

2025-09-30T13:17:22+00:00

PSP tests need the remote system to support PSP, and some PSP capable application to exchange data with. Create a simple PSP responder app which we can build and deploy to the remote host. The tests themselves can be written in Python but for ease of deploying the responder is in C (using C YNL).

net: Update threaded state in napi config in netif_set_threaded

2025-08-06T00:46:15+00:00

Commit 2677010e7793 ("Add support to set NAPI threaded for individual NAPI") added support to enable/disable threaded napi using netlink. This also extended the napi config save/restore functionality to set the napi threaded state. This breaks netdev reset for drivers that use napi threaded at device level and also use napi config save/restore on napi_disable/napi_enable. Basically on netdev with napi threaded enabled at device level, a napi_enable call will get stuck trying to stop the napi kthread. This is because the napi->config->threaded is set to disabled when threaded is enabled at device level. The issue can be reproduced on virtio-net device using qemu. To reproduce the issue run following, echo 1 > /sys/class/net/threaded ethtool -L eth0 combined 1 Update the threaded state in napi config in netif_set_threaded and add a new test that verifies this scenario.
