selftests: devlink_lib: Split out helper

2022-11-10T03:06:15Z

Merely checking whether a trap counter incremented or not without logging a test result is useful on its own. Split this functionality to a helper which will be used by subsequent patches.

selftests: devlink_lib: Add function for querying maximum pool size

2022-09-20T01:07:59Z

The maximum pool size is exposed via 'devlink sb' command. The next patch will add a test which increases some pools to the maximum size. Add a function to query the value. Signed-off-by: Amit Cohen Reviewed-by: Petr Machata Signed-off-by: Petr Machata Signed-off-by: Jakub Kicinski

selftests: mlxsw: Reduce test run time

2021-10-25T13:10:11Z

Instead of iterating over all the available trap policers, only perform the tests with three policers: The first, the last and the one in the middle of the range. On a Spectrum-3 system, this reduces the run time from almost an hour to a few minutes. Signed-off-by: Ido Schimmel Reviewed-by: Petr Machata Signed-off-by: David S. Miller

selftests/net: Use kselftest skip code for skipped tests

2021-08-24T23:49:09Z

There are several test cases in the net directory are still using exit 0 or exit 1 when they need to be skipped. Use kselftest framework skip code instead so it can help us to distinguish the return status. Criterion to filter out what should be fixed in net directory: grep -r "exit [01]" -B1 | grep -i skip This change might cause some false-positives if people are running these test scripts directly and only checking their return codes, which will change from 0 to 4. However I think the impact should be small as most of our scripts here are already using this skip code. And there will be no such issue if running them with the kselftest framework.

selftests: devlink_lib: Fix bouncing of netdevsim DEVLINK_DEV

2021-06-08T21:39:07Z

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.

selftests: forwarding: devlink_lib: Support port-less topologies

2020-09-30T21:06:54Z

Some selftests may not need any actual ports. Technically those are not forwarding selftests, but devlink_lib can still be handy. Fall back on NETIF_NO_CABLE in those cases. Signed-off-by: Petr Machata Signed-off-by: David S. Miller

selftests: forwarding: devlink_lib: Split devlink_..._set() into save & set

2020-09-30T21:06:54Z

Changing pool type from static to dynamic causes reinterpretation of threshold values. They therefore need to be saved before pool type is changed, then the pool type can be changed, and then the new values need to be set up. For that reason, set cannot subsume save, because it would be saving the wrong thing, with possibly a nonsensical value, and restore would then fail to restore the nonsensical value. Thus extract a _save() from each of the relevant _set()'s. This way it is possible to save everything up front, then to tweak it, and then restore in the required order.
