Update those to newer, more-specific ASSERT macros. This update allows to get rid of the global duration variable, which was needed by the CHECK macros Signed-off-by: Alexis Lothoré (eBPF Foundation) --- .../selftests/bpf/prog_tests/flow_dissector.c | 41 +++++++++++----------- 1 file changed, 21 insertions(+), 20 deletions(-) diff --git a/tools/testing/selftests/bpf/prog_tests/flow_dissector.c b/tools/testing/selftests/bpf/prog_tests/flow_dissector.c index 3ea25ecdf3c92959f56ba0819130b453fd2379f7..6fbe8b6dad561aec02db552caea02517ac1e2109 100644 --- a/tools/testing/selftests/bpf/prog_tests/flow_dissector.c +++ b/tools/testing/selftests/bpf/prog_tests/flow_dissector.c @@ -79,7 +79,6 @@ struct test { #define VLAN_HLEN 4 -static __u32 duration; struct test tests[] = { { .name = "ipv4", @@ -511,7 +510,7 @@ static void run_tests_skb_less(int tap_fd, struct bpf_map *keys) int i, err, keys_fd; keys_fd = bpf_map__fd(keys); - if (CHECK(keys_fd < 0, "bpf_map__fd", "err %d\n", keys_fd)) + if (!ASSERT_OK_FD(keys_fd, "bpf_map__fd")) return; for (i = 0; i < ARRAY_SIZE(tests); i++) { @@ -530,14 +529,16 @@ static void run_tests_skb_less(int tap_fd, struct bpf_map *keys) continue; err = tx_tap(tap_fd, &tests[i].pkt, sizeof(tests[i].pkt)); - CHECK(err < 0, "tx_tap", "err %d errno %d\n", err, errno); + if (!ASSERT_EQ(err, sizeof(tests[i].pkt), "tx_tap")) + continue; /* check the stored flow_keys only if BPF_OK expected */ if (tests[i].retval != BPF_OK) continue; err = bpf_map_lookup_elem(keys_fd, &key, &flow_keys); - ASSERT_OK(err, "bpf_map_lookup_elem"); + if (!ASSERT_OK(err, "bpf_map_lookup_elem")) + continue; ASSERT_MEMEQ(&flow_keys, &tests[i].keys, sizeof(struct bpf_flow_keys), @@ -553,17 +554,17 @@ static void test_skb_less_prog_attach(struct bpf_flow *skel, int tap_fd) int err, prog_fd; prog_fd = bpf_program__fd(skel->progs._dissect); - if (CHECK(prog_fd < 0, "bpf_program__fd", "err %d\n", prog_fd)) + if (!ASSERT_OK_FD(prog_fd, "bpf_program__fd")) return; err = bpf_prog_attach(prog_fd, 0, BPF_FLOW_DISSECTOR, 0); - if (CHECK(err, "bpf_prog_attach", "err %d errno %d\n", err, errno)) + if (!ASSERT_OK(err, "bpf_prog_attach")) return; run_tests_skb_less(tap_fd, skel->maps.last_dissection); err = bpf_prog_detach2(prog_fd, 0, BPF_FLOW_DISSECTOR); - CHECK(err, "bpf_prog_detach2", "err %d errno %d\n", err, errno); + ASSERT_OK(err, "bpf_prog_detach2"); } static void test_skb_less_link_create(struct bpf_flow *skel, int tap_fd) @@ -572,7 +573,7 @@ static void test_skb_less_link_create(struct bpf_flow *skel, int tap_fd) int err, net_fd; net_fd = open("/proc/self/ns/net", O_RDONLY); - if (CHECK(net_fd < 0, "open(/proc/self/ns/net)", "err %d\n", errno)) + if (!ASSERT_OK_FD(net_fd, "open(/proc/self/ns/net")) return; link = bpf_program__attach_netns(skel->progs._dissect, net_fd); @@ -582,7 +583,7 @@ static void test_skb_less_link_create(struct bpf_flow *skel, int tap_fd) run_tests_skb_less(tap_fd, skel->maps.last_dissection); err = bpf_link__destroy(link); - CHECK(err, "bpf_link__destroy", "err %d\n", err); + ASSERT_OK(err, "bpf_link__destroy"); out_close: close(net_fd); } @@ -593,18 +594,18 @@ void test_flow_dissector(void) struct bpf_flow *skel; skel = bpf_flow__open_and_load(); - if (CHECK(!skel, "skel", "failed to open/load skeleton\n")) + if (!ASSERT_OK_PTR(skel, "open/load skeleton")) return; prog_fd = bpf_program__fd(skel->progs._dissect); - if (CHECK(prog_fd < 0, "bpf_program__fd", "err %d\n", prog_fd)) - goto out_destroy_skel; + if (!ASSERT_OK_FD(prog_fd, "bpf_program__fd")) + return; keys_fd = bpf_map__fd(skel->maps.last_dissection); - if (CHECK(keys_fd < 0, "bpf_map__fd", "err %d\n", keys_fd)) - goto out_destroy_skel; + if (!ASSERT_OK_FD(keys_fd, "bpf_map__fd")) + return; err = init_prog_array(skel->obj, skel->maps.jmp_table); - if (CHECK(err, "init_prog_array", "err %d\n", err)) - goto out_destroy_skel; + if (!ASSERT_OK(err, "init_prog_array")) + return; for (i = 0; i < ARRAY_SIZE(tests); i++) { struct bpf_flow_keys flow_keys; @@ -634,17 +635,17 @@ void test_flow_dissector(void) sizeof(struct bpf_flow_keys), "returned flow keys"); } - /* Do the same tests but for skb-less flow dissector. * We use a known path in the net/tun driver that calls * eth_get_headlen and we manually export bpf_flow_keys * via BPF map in this case. */ - tap_fd = create_tap("tap0"); - CHECK(tap_fd < 0, "create_tap", "tap_fd %d errno %d\n", tap_fd, errno); + if (!ASSERT_OK_FD(tap_fd, "create_tap")) + goto out_destroy_skel; err = ifup("tap0"); - CHECK(err, "ifup", "err %d errno %d\n", err, errno); + if (!ASSERT_OK(err, "ifup")) + goto out_destroy_skel; /* Test direct prog attachment */ test_skb_less_prog_attach(skel, tap_fd);
