From dc9752075341e7beb653e37c6f4a3723074dc8bc Mon Sep 17 00:00:00 2001 From: Amit Cohen Date: Wed, 2 Mar 2022 18:14:46 +0200 Subject: selftests: mlxsw: tc_police_scale: Make test more robust The test adds tc filters and checks how many of them were offloaded by grepping for 'in_hw'. iproute2 commit f4cd4f127047 ("tc: add skip_hw and skip_sw to control action offload") added offload indication to tc actions, producing the following output: $ tc filter show dev swp2 ingress ... filter protocol ipv6 pref 1000 flower chain 0 handle 0x7c0 eth_type ipv6 dst_ip 2001:db8:1::7bf skip_sw in_hw in_hw_count 1 action order 1: police 0x7c0 rate 10Mbit burst 100Kb mtu 2Kb action drop overhead 0b ref 1 bind 1 not_in_hw used_hw_stats immediate The current grep expression matches on both 'in_hw' and 'not_in_hw', resulting in incorrect results. Fix that by using JSON output instead.

Currently, the check of the return value of each test case is in the wrong place, which can result in the wrong return value. For example: # TESTS='tc_police' ./resource_scale.sh TEST: 'tc_police' [default] 968 [FAIL] tc police offload count failed Error: mlxsw_spectrum: Failed to allocate policer index. We have an error talking to the kernel Command failed /tmp/tmp.i7Oc5HwmXY:969 TEST: 'tc_police' [default] overflow 969 [ OK ] ... TEST: 'tc_police' [ipv4_max] overflow 969 [ OK ] $ echo $? 0 Fix this by moving the check to be done after each test case.
