selftests: netdevsim: hw_stats_l3: Add a new test

2022-03-15T13:00:51+00:00

Add a test that verifies basic UAPI contracts, netdevsim operation,
rollbacks after partial enablement in core, and UAPI notifications.

selftests: forwarding: tests of locked port feature

2022-02-23T12:52:34+00:00

These tests check that the basic locked port feature works, so that
no 'host' can communicate (ping) through a locked port unless the
MAC address of the 'host' interface is in the forwarding database of
the bridge.

selftests: net: bridge: Parameterize ageing timeout

2022-02-03T14:05:56+00:00

Allow the ageing timeout that is set on bridges to be customized from
forwarding.config. This allows the tests to be run on hardware which
does not support a 10s timeout (e.g. mv88e6xxx).

selftests: lib.sh: Add PING_COUNT to allow sending configurable amount of packets

2021-12-23T01:14:32+00:00

Currently `ping_do()` and `ping6_do()` send 10 packets.

There are cases that it is not possible to catch only the interesting
packets using tc rule, so then, it is possible to send many packets and
verify that at least this amount of packets hit the rule.

Add `PING_COUNT` variable, which is set to 10 by default, to allow tests
sending more than 10 packets using the existing ping API.

selftests: mlxsw: Add helpers for skipping selftests

2021-10-25T13:10:11+00:00

A number of mlxsw-specific selftests currently detect whether they are run
on a compatible machine, and bail out silently when not. These tests are
however done in a somewhat impenetrable manner by directly comparing PCI
IDs against a blacklist or a whitelist, and bailing out silently if the
machine is not compatible.

Instead, add a helper, mlxsw_only_on_spectrum(), which allows specifying
the supported machines in a human-readable manner. If the current machine
is incompatible, the helper emits a SKIP message and returns an error code,
based on which the caller can gracefully bail out in a suitable way. This
allows a more readable conditions such as:

	mlxsw_only_on_spectrum 2+ || return

Convert all existing open-coded guards to the new helper. Also add two new
guards to do_mark_test() and do_drop_test(), which are supported only on
Spectrum-2+, but the corresponding check was not there.

selftests: lib: forwarding: allow tests to not require mz and jq

2021-10-25T11:59:42+00:00

These programs are useful, but not all selftests require them.

Additionally, on embedded boards without package management (things like
buildroot), installing mausezahn or jq is not always as trivial as
downloading a package from the web.

So it is actually a bit annoying to require programs that are not used.
Introduce options that can be set by scripts to not enforce these
dependencies. For compatibility, default to "yes".

ipv6: When forwarding count rx stats on the orig netdev

2021-10-15T22:32:04+00:00

Commit bdb7cc643fc9 ("ipv6: Count interface receive statistics on the
ingress netdev") does not work when ip6_forward() executes on the skbs
with vrf-enslaved netdev. Use IP6CB(skb)->iif to get to the right one.

Add a selftest script to verify.

selftests/net: Use kselftest skip code for skipped tests

2021-08-24T23:49:09+00:00

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.
