From: Geliang Tang <tanggeliang@xxxxxxxxxx> Although the "Segmentation fault" errors are fixed in the last commit, run bpf_tcp_ca selftests (./test_progs -t bpf_tcp_ca) on a Loongarch platform, still some other "ENOTSUPP" (-524) errors left since lacking BPF trampoline on Loongarch: ''' test_dctcp:PASS:bpf_dctcp__open_and_load 0 nsec test_dctcp:FAIL:bpf_map__attach_struct_ops unexpected error: -524 #29/1 bpf_tcp_ca/dctcp:FAIL test_cubic:PASS:bpf_cubic__open_and_load 0 nsec test_cubic:FAIL:bpf_map__attach_struct_ops unexpected error: -524 #29/2 bpf_tcp_ca/cubic:FAIL #29/3 bpf_tcp_ca/invalid_license:OK test_dctcp_fallback:PASS:dctcp_skel 0 nsec test_dctcp_fallback:PASS:bpf_dctcp__load 0 nsec test_dctcp_fallback:FAIL:dctcp link unexpected error: -524 #29/4 bpf_tcp_ca/dctcp_fallback:FAIL #29/5 bpf_tcp_ca/rel_setsockopt:OK test_write_sk_pacing:PASS:open_and_load 0 nsec test_write_sk_pacing:FAIL:attach_struct_ops unexpected error: -524 #29/6 bpf_tcp_ca/write_sk_pacing:FAIL #29/7 bpf_tcp_ca/incompl_cong_ops:OK #29/8 bpf_tcp_ca/unsupp_cong_op:OK test_update_ca:PASS:open 0 nsec test_update_ca:FAIL:attach_struct_ops unexpected error: -524 #29/9 bpf_tcp_ca/update_ca:FAIL test_update_wrong:PASS:open 0 nsec test_update_wrong:FAIL:attach_struct_ops unexpected error: -524 #29/10 bpf_tcp_ca/update_wrong:FAIL test_mixed_links:PASS:open 0 nsec test_mixed_links:FAIL:attach_struct_ops_nl unexpected error: -524 test_mixed_links:FAIL:attach_struct_ops unexpected error: -524 #29/11 bpf_tcp_ca/mixed_links:FAIL test_multi_links:PASS:open 0 nsec test_multi_links:FAIL:attach_struct_ops_1st unexpected error: -524 test_multi_links:FAIL:attach_struct_ops_2nd unexpected error: -524 #29/12 bpf_tcp_ca/multi_links:FAIL test_link_replace:PASS:open 0 nsec test_link_replace:FAIL:attach_struct_ops_1st unexpected error: -524 test_link_replace:FAIL:attach_struct_ops_2nd unexpected error: -524 #29/13 bpf_tcp_ca/link_replace:FAIL #29/14 bpf_tcp_ca/tcp_ca_kfunc:OK test_cc_cubic:PASS:bpf_cc_cubic__open_and_load 0 nsec test_cc_cubic:FAIL:bpf_map__attach_struct_ops unexpected error: -524 #29/15 bpf_tcp_ca/cc_cubic:FAIL #29 bpf_tcp_ca:FAIL ''' Just like in ASSERT_OK(), this patch uses test_progs_get_error() helper to skip ENOTSUPP (524) and ENOTSUP (95) in ASSERT_OK_PTR() too.
