[PATCH AUTOSEL 5.15 22/69] selftests: mlxsw: resource_scale: Allow skipping a test

by Sasha Levin

From: Petr Machata <petrm(a)nvidia.com> [ Upstream commit 8cad339db339a39cb82b1188e4be4070a433abac ] The scale tests are currently testing two things: that some number of instances of a given resource can actually be created; and that when an attempt is made to create more than the supported amount, the failures are noted and handled gracefully. Sometimes the scale test depends on more than one resource. In particular, a following patch will add a RIF counter scale test, which depends on the number of RIF counters that can be bound, and also on the number of RIFs that can be created. When the test is limited by the auxiliary resource and not by the primary one, there's no point trying to run the overflow test, because it would be testing exhaustion of the wrong resource. To support this use case, when the $test_get_target yields 0, skip the test instead.

Currently, the core_reloc tests have some negative tests. In Commit 704c91e59fe0, for core_reloc_btfgen, all negative tests are skipped with the following condition if (!test_case->btf_src_file || test_case->fails) { test__skip(); continue; } This is too conservative. Negative tests do not fail mkstemp() and run_btfgen() should not be skipped. There are a few negative tests indeed failing run_btfgen() and this patch added 'run_btfgen_fails' to mark these tests so that they can be skipped for btfgen tests.

[PATCH AUTOSEL 5.19 071/105] selftests/bpf: Do not attach kprobe_multi bench to bpf_dispatcher_xdp_func

[PATCH AUTOSEL 5.19 027/105] selftests: mlxsw: resource_scale: Allow skipping a test

by Sasha Levin

From: Petr Machata <petrm(a)nvidia.com> [ Upstream commit 8cad339db339a39cb82b1188e4be4070a433abac ] The scale tests are currently testing two things: that some number of instances of a given resource can actually be created; and that when an attempt is made to create more than the supported amount, the failures are noted and handled gracefully. Sometimes the scale test depends on more than one resource. In particular, a following patch will add a RIF counter scale test, which depends on the number of RIF counters that can be bound, and also on the number of RIFs that can be created. When the test is limited by the auxiliary resource and not by the primary one, there's no point trying to run the overflow test, because it would be testing exhaustion of the wrong resource. To support this use case, when the $test_get_target yields 0, skip the test instead.
