selftests: mlxsw: qos_mc_aware: Specify arping timeout as an integer

2020-05-22T23:08:14Z

Starting from iputils s20190709 (used in Fedora 31), arping does not support timeout being specified as a decimal: $ arping -c 1 -I swp1 -b 192.0.2.66 -q -w 0.1 arping: invalid argument: '0.1' Previously, such timeouts were rounded to an integer. Fix this by specifying the timeout as an integer.

selftests: netdevsim: Always initialize 'RET' variable

2020-05-22T23:05:42Z

The variable is used by log_test() to check if the test case completely successfully or not. In case it is not initialized at the start of a test case, it is possible for the test case to fail despite not encountering any errors. Example: ``` ... TEST: Trap group statistics [ OK ] TEST: Trap policer [FAIL] Policer drop counter was not incremented TEST: Trap policer binding [FAIL] Policer drop counter was not incremented ``` Failure of trap_policer_test() caused trap_policer_bind_test() to fail as well. Fix by adding missing initialization of the variable.

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

2020-04-03T20:12:26Z

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 .gitignore: remove too obvious comments

2020-03-31T00:54:59Z

Add test cases for packet trap policer set / show commands as well as for the binding of these policers to packet trap groups. Both good and bad flows are tested for maximum coverage. v2: * Add test case with new 'fail_trap_policer_set' knob * Add test case for partially modified trap group Signed-off-by: Ido Schimmel Signed-off-by: David S.

netdevsim: Change dummy reporter auto recover default

2020-03-30T18:17:34Z

Health reporters should be registered with auto recover set to true. Align dummy reporter behaviour with that, as in later patch the option to set auto recover behaviour will be removed. In addition, align netdevsim selftest to the new default value. Signed-off-by: Eran Ben Elisha Reviewed-by: Jiri Pirko Signed-off-by: David S. Miller
