2021-08-17selftests/bpf: Fix flaky send_signal testYonghong Song1-0/+16
libbpf CI has reported send_signal test is flaky although I am not able to reproduce it in my local environment. But I am able to reproduce with on-demand libbpf CI ([1]). Through code analysis, the following is possible reason. The failed subtest runs bpf program in softirq environment. Since bpf_send_signal() only sends to a fork of "test_progs" process. If the underlying current task is not "test_progs", bpf_send_signal() will not be triggered and the subtest will fail. To reduce the chances where the underlying process is not the intended one, this patch boosted scheduling priority to -20 (highest allowed by setpriority() call). And I did 10 runs with on-demand libbpf CI with this patch and I didn't observe any failures.

This patch adds '-a' and '-d' arguments supporting both exact string match as well as using '*' wildcard in test/subtests selection. '-a' and '-t' can co-exists, same as '-d' and '-b', in which case they just add to the list of allowed or denied test selectors. Caveat: Same as the current substring matching mechanism, test and subtest selector applies independently, 'a*/b*' will execute all tests matching "a*", and with subtest name matching "b*", but tests matching "a*" that has no subtests will also be executed.

2021-08-17selftests: net: improved IOAM testsJustin Iurman2-401/+1074
As previously discussed with David Ahern, here is a refactored and improved version of the IOAM self-test. It is now more complete and more robust. Now, all tests are divided into three categories: OUTPUT (evaluates the IOAM processing by the sender), INPUT (evaluates the IOAM processing by the receiver) and GLOBAL (evaluates wider use cases that do not fall into the other two categories). Both OUTPUT and INPUT tests only use a two-node topology (alpha and beta), while GLOBAL tests use the entire three-node topology (alpha, beta, gamma). Each test is documented inside its own handler in the (bash) script. Signed-off-by: Justin Iurman <[email protected]> Signed-off-by: David S. Miller <[email protected]>

Extend attach_probe selftests to specify ref_ctr_offset for uprobe/uretprobe and validate that its value is incremented from zero. Turns out that once uprobe is attached with ref_ctr_offset, uretprobe for the same location/function *has* to use ref_ctr_offset as well, otherwise perf_event_open() fails with -EINVAL. So this test uses ref_ctr_offset for both uprobe and uretprobe, even though for the purpose of test uprobe would be enough.

2021-08-17selftests/bpf: Add bpf_cookie selftests for high-level APIsAndrii Nakryiko2-0/+339
Add selftest with few subtests testing proper bpf_cookie usage. Kprobe and uprobe subtests are pretty straightforward and just validate that the same BPF program attached with different bpf_cookie will be triggered with those different bpf_cookie values. Tracepoint subtest is a bit more interesting, as it is the only perf_event-based BPF hook that shares bpf_prog_array between multiple perf_events internally. This means that the same BPF program can't be attached to the same tracepoint multiple times. So we have 3 identical copies. This arrangement allows to test bpf_prog_array_copy()'s handling of bpf_prog_array list manipulation logic when programs are attached and detached. The test validates that bpf_cookie isn't mixed up and isn't lost during such list manipulations. Perf_event subtest validates that two BPF links can be created against the same perf_event (but not at the same time, only one BPF program can be attached to perf_event itself), and that for each we can specify different bpf_cookie value.

2021-08-13selftests/bpf: Fix test_core_autosize on big-endian machinesIlya Leoshkevich1-5/+15
The "probed" part of test_core_autosize copies an integer using bpf_core_read() into an integer of a potentially different size. On big-endian machines a destination offset is required for this to produce a sensible result.

2021-08-13libbpf: Support weak typed ksyms.Hao Luo2-0/+87
Currently weak typeless ksyms have default value zero, when they don't exist in the kernel. However, weak typed ksyms are rejected by libbpf if they can not be resolved. This means that if a bpf object contains the declaration of a nonexistent weak typed ksym, it will be rejected even if there is no program that references the symbol. Nonexistent weak typed ksyms can also default to zero just like typeless ones. This allows programs that access weak typed ksyms to be accepted by verifier, if the accesses are guarded. For example, extern const int bpf_link_fops3 __ksym __weak; /* then in BPF program */ if (&bpf_link_fops3) { /* use bpf_link_fops3 */ } If actual use of nonexistent typed ksym is not guarded properly, verifier would see that register is not PTR_TO_BTF_ID and wouldn't allow to use it for direct memory reads or passing it to BPF helpers.

2021-08-13selftests/bpf: Fix running of XDP bonding testsJussi Maki1-3/+3
An "innocent" cleanup in the last version of the XDP bonding patchset moved the "test__start_subtest" calls to the test main function, but I forgot to reverse the condition, which lead to all tests being skipped.

2021-08-13kunit: Print test statistics on failureDavid Gow1-1/+1
When a number of tests fail, it can be useful to get higher-level statistics of how many tests are failing (or how many parameters are failing in parameterised tests), and in what cases or suites. This is already done by some non-KUnit tests, so add support for automatically generating these for KUnit tests. This change adds a 'kunit.stats_enabled' switch which has three values: - 0: No stats are printed (current behaviour) - 1: Stats are printed only for tests/suites with more than one subtest (new default) - 2: Always print test statistics For parameterised tests, the summary line looks as follows: " # inode_test_xtimestamp_decoding: pass:16 fail:0 skip:0 total:16" For test suites, there are two lines looking like this: "# ext4_inode_test: pass:1 fail:0 skip:0 total:1" "# Totals: pass:16 fail:0 skip:0 total:16" The first line gives the number of direct subtests, the second "Totals" line is the accumulated sum of all tests and test parameters. This format is based on the one used by kselftest[1].

2021-08-13kunit: tool: make --raw_output support only showing kunit outputDaniel Latypov3-9/+24
--raw_output is nice, but it would be nicer if could show only output after KUnit tests have started. So change the flag to allow specifying a string ('kunit'). Make it so `--raw_output` alone will default to `--raw_output=all` and have the same original behavior. Drop the small kunit_parser.raw_output() function since it feels wrong to put it in "kunit_parser.py" when the point of it is to not parse anything. E.g. $ ./tools/testing/kunit/kunit.py run --raw_output=kunit ... [15:24:07] Starting KUnit Kernel ... TAP version 14 1..1 # Subtest: example 1..3 # example_simple_test: initializing ok 1 - example_simple_test # example_skip_test: initializing # example_skip_test: You should not see a line below. ok 2 - example_skip_test # SKIP this test should be skipped # example_mark_skipped_test: initializing # example_mark_skipped_test: You should see a line below. # example_mark_skipped_test: You should see this line. ok 3 - example_mark_skipped_test # SKIP this test should be skipped ok 1 - example [15:24:10] Elapsed time: 6.487s total, 0.001s configuring, 3.510s building, 0.000s running Signed-off-by: Daniel Latypov <[email protected]> Reviewed-by: David Gow <[email protected]> Signed-off-by: Shuah Khan <[email protected]>
2021-08-13kunit: tool: add --kernel_args to allow setting module paramsDaniel Latypov2-10/+26
kunit.py currently does not make it possible for users to specify module parameters (/kernel arguments more generally) unless one directly tweaks the kunit.py code itself. This hasn't mattered much so far, but this would make it easier to port existing tests that expose module parameters over to KUnit and/or let current KUnit tests take advantage of them. Tested using an kunit internal parameter: $ ./tools/testing/kunit/kunit.py run --kunitconfig=lib/kunit \ --kernel_args=kunit.filter_glob=kunit_status ... Testing complete. 2 tests run. 0 failed. 0 crashed. 0 skipped.
