2025-05-27selftests: net: move wait_local_port_listen to lib.shHangbin Liu
The function wait_local_port_listen() is the only function defined in net_helper.sh. Since some tests source both lib.sh and net_helper.sh, we can simplify the setup by moving wait_local_port_listen() to lib.sh. With this change, net_helper.sh becomes redundant and can be removed.

2024-02-27selftests: netdevsim: be less selective for FW for the devlink testJakub Kicinski
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.

2023-02-21sefltests: netdevsim: wait for devlink instance after netns removalJiri Pirko
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.

2021-06-08selftests: devlink_lib: Fix bouncing of netdevsim DEVLINK_DEVPetr Machata
In the commit referenced below, a check was added to devlink_lib that asserts the existence of a devlink device referenced by $DEVLINK_DEV. Unfortunately, several netdevsim tests point DEVLINK_DEV at a device that does not exist at the time that devlink_lib is sourced. Thus these tests spuriously fail. Fix this by introducing an override. By setting DEVLINK_DEV to an empty string, the user declares their intention to handle DEVLINK_DEV management on their own. In all netdevsim tests that use devlink_lib and set DEVLINK_DEV, set instead an empty DEVLINK_DEV just before sourcing devlink_lib, and set it to the correct value right afterwards.

2020-09-26netdevsim: fix duplicated debugfs directoryJakub Kicinski
The "ethtool" debugfs directory holds per-netdev knobs, so move it from the device instance directory to the port directory. This fixes the following warning when creating multiple ports: debugfs: Directory 'ethtool' with parent 'netdevsim1' already present!

2020-09-25netdevsim: add support for flash_update overwrite maskJacob Keller
The devlink interface recently gained support for a new "overwrite mask" parameter that allows specifying how various sub-sections of a flash component are modified when updating. Add support for this to netdevsim, to enable easily testing the interface. Make the allowed overwrite mask values controllable via a debugfs parameter. This enables testing a flow where the driver rejects an unsupportable overwrite mask.

2020-09-25devlink: convert flash_update to use params structureJacob Keller
The devlink core recently gained support for checking whether the driver supports a flash_update parameter, via `supported_flash_update_params`. However, parameters are specified as function arguments. Adding a new parameter still requires modifying the signature of the .flash_update callback in all drivers. Convert the .flash_update function to take a new `struct devlink_flash_update_params` instead. By using this structure, and the `supported_flash_update_params` bit field, a new parameter to flash_update can be added without requiring modification to existing drivers. As before, all parameters except file_name will require driver opt-in. Because file_name is a necessary field to for the flash_update to make sense, no "SUPPORTED" bitflag is provided and it is always considered valid. All future additional parameters will require a new bit in the supported_flash_update_params bitfield.
