selftests: forwarding: Add missing 'rp_filter' configuration

2020-10-18T19:47:32+00:00

When 'rp_filter' is configured in strict mode (1) the tests fail because
packets received from the macvlan netdevs would not be forwarded through
them on the reverse path.

Fix this by disabling the 'rp_filter', meaning no source validation is
performed.

selftests: ocelot: add some example VCAP IS1, IS2 and ES0 tc offloads

2020-10-02T22:40:30+00:00

Provide an example script which can be used as a skeleton for offloading
TCAM rules in the Ocelot switches.

Not all actions are demoed, mostly because of difficulty to automate
this from a single board.

For example, policing. We can set up an iperf3 UDP server and client and
measure throughput at destination. But at least with DSA setups, network
namespacing the individual ports is not possible because all switch
ports are handled by the same DSA master. And we cannot assume that the
target platform (an embedded board) has 2 other non-switch generator
ports, we need to work with the generator ports as switch ports (this is
the reason why mausezahn is used, and not IP traffic like ping). When
somebody has an idea how to test policing, that can be added to this
test.

selftests: forwarding: devlink_lib: Support port-less topologies

2020-09-30T21:06:54+00:00

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.

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

2020-09-30T21:06:54+00:00

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.

selftests: forwarding: Fix mausezahn delay parameter in mirror_test()

2020-08-25T00:36:11+00:00

Currently, mausezahn delay parameter in mirror_test() is specified with
'ms' units.

mausezahn versions before 0.6.5 interpret 'ms' as seconds and therefore
the tests that use mirror_test() take a very long time to complete.

Resolve this by specifying 'msec' units.

selftests: ethtool: Fix test when only two speeds are supported

2020-07-29T19:16:21+00:00

The test case check_highest_speed_is_chosen() configures $h1 to
advertise a subset of its supported speeds and checks that $h2 chooses
the highest speed from the subset.

To find the common advertised speeds between $h1 and $h2,
common_speeds_get() is called.

Currently, the first speed returned from common_speeds_get() is removed
claiming "h1 does not advertise this speed". The claim is wrong because
the function is called after $h1 already advertised a subset of speeds.

In case $h1 supports only two speeds, it will advertise a single speed
which will be later removed because of previously mentioned bug. This
results in the test needlessly failing. When more than two speeds are
supported this is not an issue because the first advertised speed
is the lowest one.

Fix this by not removing any speed from the list of commonly advertised
speeds.
