selftest: netdevsim: test devlink default params

2025-11-21T03:01:23+00:00

Test querying default values and resetting to default values for netdevsim devlink params. This should cover the basic paths of interest: driverinit and non-driverinit cmodes, as well as bool and non-bool value type. Default param values of type bool are encoded with u8 netlink type as opposed to flag type, so that userspace can distinguish "not-present" from false.

netdevsim: add fw_update_flash_chunk_time_ms debugfs knobs

2025-07-24T00:08:56+00:00

Netdevsim emulates firmware update and it takes 5 seconds to complete. For some use cases, this is too long and unnecessary. Allow user to configure the time by exposing debugfs a knob to set chunk time.

selftests: netdevsim: be less selective for FW for the devlink test

2024-02-27T14:20:08+00:00

Commit 6151ff9c7521 ("selftests: netdevsim: use suitable existing dummy file for flash test") introduced a nice trick to the devlink flashing test. Instead of user having to create a file under /lib/firmware we just pick the first one that already exists. Sadly, in AWS Linux there are no files directly under /lib/firmware, only in subdirectories. Don't limit the search to -maxdepth 1. We can use the %P print format to get the correct path for files inside subdirectories: $ find /lib/firmware -type f -printf '%P\n' | head -1 intel-ucode/06-1a-05 The full path is /lib/firmware/intel-ucode/06-1a-05 This works in GNU find, busybox doesn't have printf at all, so we're not making it worse.

selftests: netdevsim: use suitable existing dummy file for flash test

2023-10-13T09:43:13+00:00

The file name used in flash test was "dummy" because at the time test was written, drivers were responsible for file request and as netdevsim didn't do that, name was unused. However, the file load request is now done in devlink code and therefore the file has to exist. Use first random file from /lib/firmware for this purpose.

sefltests: netdevsim: wait for devlink instance after netns removal

2023-02-21T12:02:42+00:00

When devlink instance is put into network namespace and that network namespace gets deleted, devlink instance is moved back into init_ns. This is done as a part of cleanup_net() routine. Since cleanup_net() is called asynchronously from workqueue, there is no guarantee that the devlink instance move is done after "ip netns del" returns. So fix this race by making sure that the devlink instance is present before any other operation.

selftests: devlink: fix the fd redirect in dummy_reporter_test

2022-12-16T10:21:36+00:00

$number + > bash means redirect FD $number, e.g. commonly used 2> redirects stderr (fd 2). The test uses 8192> to write the number 8192 to a file, this results in: ./devlink.sh: line 499: 8192: Bad file descriptor Oddly the test also papers over this issue by checking for failure (expecting an error rather than success) so it passes, anyway.
