selftests: mlxsw: resource_scale: Fix return value

2022-03-08T18:14:17Z

[ Upstream commit 196f9bc050cbc5085b4cbb61cce2efe380bc66d0 ] The test runs several test cases and is supposed to return an error in case at least one of them failed. 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.

selftests: mlxsw: tc_police_scale: Make test more robust

2022-03-08T18:14:12Z

commit dc9752075341e7beb653e37c6f4a3723074dc8bc upstream. 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.

selftests: mlxsw: Add a test case for MAC profiles consolidation

2021-12-14T12:56:10Z

Add a test case to cover the bug fixed by the previous patch. Edit the MAC address of one netdev so that it matches the MAC address of the second netdev. Verify that the two MAC profiles were consolidated by testing that the MAC profiles occupancy decreased by one. Signed-off-by: Danielle Ratson Signed-off-by: Ido Schimmel Signed-off-by: David S.

selftests: mlxsw: Test offloadability of root TBF

2021-10-29T02:47:49Z

TBF can be used as a root qdisc, with the usual ETS/RED/TBF hierarchy below it. This use should now be offloaded. Add a test that verifies that it is. Signed-off-by: Petr Machata Signed-off-by: Ido Schimmel Signed-off-by: Jakub Kicinski

selftests: mlxsw: Remove deprecated test cases

2021-10-26T12:35:58Z

After adding the previous patches, the constraint that all the router interface MAC addresses have the same prefix is no longer relevant. Remove the test cases that validated that this constraint is honored. Signed-off-by: Danielle Ratson Signed-off-by: Ido Schimmel Signed-off-by: David S. Miller

selftests: Add an occupancy test for RIF MAC profiles

2021-10-26T12:35:58Z

When all the RIF MAC profiles are in use, test that it is possible to change the MAC of a netdev (i.e., a RIF) when its MAC profile is not shared with other RIFs. Test that replacement fails when the MAC profile is shared. Signed-off-by: Danielle Ratson Signed-off-by: Ido Schimmel Signed-off-by: David S. Miller

selftests: mlxsw: Add forwarding test for RIF MAC profiles

2021-10-26T12:35:58Z

Verify that MAC profile changes are indeed applied and that packets are forwarded with the correct source MAC. Output example: $ ./rif_mac_profiles.sh TEST: h1->h2: new mac profile [ OK ] TEST: h2->h1: new mac profile [ OK ] TEST: h1->h2: edit mac profile [ OK ] TEST: h2->h1: edit mac profile [ OK ] Signed-off-by: Danielle Ratson Signed-off-by: Ido Schimmel Signed-off-by: David S.

selftests: mlxsw: Add a scale test for RIF MAC profiles

2021-10-26T12:35:58Z

Query the maximum number of supported RIF MAC profiles using devlink-resource and verify that all available MAC profiles can be utilized and that an error is generated when user space tries to exceed this number. Output example in Spectrum-2: $ TESTS='rif_mac_profile' ./resource_scale.sh TEST: 'rif_mac_profile' 4 [ OK ] TEST: 'rif_mac_profile' overflow 5 [ OK ] Signed-off-by: Danielle Ratson Signed-off-by: Ido Schimmel Signed-off-by: David S.

selftests: mlxsw: Reduce test run time

2021-10-25T13:10:11Z

Instead of iterating over all the available trap policers, only perform the tests with three policers: The first, the last and the one in the middle of the range. On a Spectrum-3 system, this reduces the run time from almost an hour to a few minutes. Signed-off-by: Ido Schimmel Reviewed-by: Petr Machata Signed-off-by: David S. Miller

selftests: mlxsw: Use permanent neighbours instead of reachable ones

2021-10-25T13:10:11Z

The nexthop objects tests configure dummy reachable neighbours so that the nexthops will have a MAC address and be programmed to the device. Since these are dummy reachable neighbours, they can be transitioned by the kernel to a failed state if they are around for too long. This can happen, for example, if the "TIMEOUT" variable is configured with a too high value. Make the tests more robust by configuring the neighbours as permanent, so that the tests do not depend on the configured timeout value.
