From: Geliang Tang <tanggeliang@xxxxxxxxxx> There are so many "ENOTSUPP" (-524) errors when running BPF selftests on a Loongarch platform since lacking BPF trampoline on Loongarch: ''' test_d_path_basic:PASS:setup 0 nsec libbpf: prog 'prog_stat': failed to attach: unknown error (-524) libbpf: prog 'prog_stat': failed to auto-attach: -524 test_d_path_basic:FAIL:setup attach failed: -524 #77/1 d_path/basic:FAIL #77/2 d_path/check_rdonly_mem:OK #77/3 d_path/check_alloc_mem:OK #77 d_path:FAIL ... ... test_module_attach:PASS:skel_open 0 nsec test_module_attach:PASS:set_attach_target 0 nsec test_module_attach:PASS:set_attach_target_explicit 0 nsec test_module_attach:PASS:skel_load 0 nsec libbpf: prog 'handle_fentry': failed to attach: unknown error (-524) libbpf: prog 'handle_fentry': failed to auto-attach: -524 test_module_attach:FAIL:skel_attach skeleton attach failed: -524 #167 module_attach:FAIL ... ... ringbuf_subtest:PASS:skel_open 0 nsec ringbuf_subtest:PASS:skel_load 0 nsec ringbuf_subtest:PASS:rw_cons_pos 0 nsec ringbuf_subtest:PASS:rw_extend 0 nsec ringbuf_subtest:PASS:exec_cons_pos_protect 0 nsec ringbuf_subtest:PASS:unmap_rw 0 nsec ringbuf_subtest:PASS:wr_prod_pos 0 nsec ringbuf_subtest:PASS:wr_prod_pos_err 0 nsec ringbuf_subtest:PASS:wr_data_page_one 0 nsec ringbuf_subtest:PASS:wr_data_page_one_err 0 nsec ringbuf_subtest:PASS:wr_data_page_two 0 nsec ringbuf_subtest:PASS:wr_data_page_all 0 nsec ringbuf_subtest:PASS:ro_prod_pos 0 nsec ringbuf_subtest:PASS:write_protect 0 nsec ringbuf_subtest:PASS:exec_protect 0 nsec ringbuf_subtest:PASS:ro_remap 0 nsec ringbuf_subtest:PASS:unmap_ro 0 nsec ringbuf_subtest:PASS:ro_prod_pos 0 nsec ringbuf_subtest:PASS:write_protect 0 nsec ringbuf_subtest:PASS:exec_protect 0 nsec ringbuf_subtest:PASS:ro_remap 0 nsec ringbuf_subtest:PASS:unmap_ro 0 nsec ringbuf_subtest:PASS:ringbuf_create 0 nsec ringbuf_subtest:FAIL:skel_attach skeleton attachment failed: -1 #277/1 ringbuf/ringbuf:FAIL #277/2 ringbuf/ringbuf_n:SKIP #277/3 ringbuf/ringbuf_map_key:SKIP #277 ringbuf:FAIL ... ... test_test_bprm_opts:PASS:skel_load 0 nsec libbpf: prog 'secure_exec': failed to attach: unknown error (-524) libbpf: prog 'secure_exec': failed to auto-attach: -524 test_test_bprm_opts:FAIL:attach attach failed: -524 #382 test_bprm_opts:FAIL ... ... test_test_ima:PASS:skel_load 0 nsec test_test_ima:PASS:ringbuf 0 nsec libbpf: prog 'bprm_committed_creds': failed to attach: \ unknown error (-524) libbpf: prog 'bprm_committed_creds': failed to auto-attach: -524 test_test_ima:FAIL:attach attach failed: -524 #384 test_ima:FAIL ... ... test_trace_ext:PASS:setup 0 nsec test_trace_ext:PASS:setup 0 nsec test_trace_ext:PASS:setup 0 nsec test_trace_ext:PASS:setup 0 nsec libbpf: prog 'test_pkt_md_access_new': failed to attach: \ unknown error (-524) libbpf: prog 'test_pkt_md_access_new': failed to auto-attach: -524 test_trace_ext:FAIL:setup freplace/test_pkt_md_access attach failed: -524 #397 trace_ext:FAIL ''' This patch uses ASSERT_OK() instead of CHECK() to skip these "ENOTSUPP" errors.
