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.

selftests: forwarding: pedit_dsfield: Check counter value

2020-05-31T04:48:24+00:00

A missing stats_update callback was recently added to act_pedit. Now that
iproute2 supports JSON dumping for pedit, extend the pedit_dsfield selftest
with a check that would have caught the fact that the callback was missing.

selftests: forwarding: mirror_lib: Use mausezahn

2020-05-31T04:48:24+00:00

Using ping in tests is error-prone, because ping is too smart. On a
flaky system (notably in a simulator), when packets don't come quickly
enough, more pings are sent, and that throws off counters. Instead use
mausezahn to generate ICMP echo request packets. That allows us to
send them in quicker succession as well, because the reason the ping
was made slow in the first place was to make the tests work on
simulated systems.

Merge tag 'spdx-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx

2020-04-03T20:12:26+00:00

Pull SPDX updates from Greg KH:
 "Here are three SPDX patches for 5.7-rc1.

  One fixes up the SPDX tag for a single driver, while the other two go
  through the tree and add SPDX tags for all of the .gitignore files as
  needed.

  Nothing too complex, but you will get a merge conflict with your
  current tree, that should be trivial to handle (one file modified by
  two things, one file deleted.)

  All three of these have been in linux-next for a while, with no
  reported issues other than the merge conflict"

* tag 'spdx-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx:
  ASoC: MT6660: make spdxcheck.py happy
  .gitignore: add SPDX License Identifier

selftests: mlxsw: Add test cases for devlink-trap policers

2020-03-31T00:54:59+00:00

Add test cases that verify that each registered packet trap policer:

* Honors that imposed limitations of rate and burst size
* Able to police trapped packets to the specified rate
* Able to police trapped packets to the specified burst size
* Able to be unbound from its trap group
