Commit 704c91e59fe0 ('selftests/bpf: Test "bpftool gen min_core_btf"') added a test test_core_btfgen to test core relocation with btf generated with 'bpftool gen min_core_btf'. Currently, among 76 subtests, 25 are skipped. ... #46/69 core_reloc_btfgen/enumval:OK #46/70 core_reloc_btfgen/enumval___diff:OK #46/71 core_reloc_btfgen/enumval___val3_missing:OK #46/72 core_reloc_btfgen/enumval___err_missing:SKIP #46/73 core_reloc_btfgen/enum64val:OK #46/74 core_reloc_btfgen/enum64val___diff:OK #46/75 core_reloc_btfgen/enum64val___val3_missing:OK #46/76 core_reloc_btfgen/enum64val___err_missing:SKIP ... #46 core_reloc_btfgen:SKIP Summary: 1/51 PASSED, 25 SKIPPED, 0 FAILED Alexei found that in the above core_reloc_btfgen/enum64val___err_missing should not be skipped. 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. With this, we have ... ... Summary: 1/62 PASSED, 14 SKIPPED, 0 FAILED Totally 14 subtests are skipped instead of 25.
