Before:
$ ./tools/testing/kunit/kunit.py parse /dev/null
...
[ERROR] Test : invalid KTAP input!
After:
$ ./tools/testing/kunit/kunit.py parse /dev/null
...
[ERROR] Test <missing>: could not find any KTAP output!
This error message gets printed out when extract_tap_output() yielded no
lines. So while it could be because of malformed KTAP output from KUnit,
it could also be due to not having any KTAP output at all.
Try and make the error message here more clear.

Note: this potentially breaks custom qemu_configs if people are using
them! But the fix for them is simple, don't specify multiple arguments
in one string and don't add on a redundant ''.
It feels a bit iffy to be using a shell in the first place.
There's the usual shenanigans where people could pass in arbitrary shell
commands via --kernel_arg (since we're just adding '' around the
kernel_cmdline) or via a custom qemu_config.
This isn't too much of a concern given the nature of this script (and
the qemu_config file is in python, you can do w/e you want already).
But it does have some other drawbacks.
One example of a kunit-specific pain point:
If the relevant qemu binary is missing, we get output like this:
> /bin/sh: line 1: qemu-system-aarch64: command not found
This in turn results in our KTAP parser complaining about
missing/invalid KTAP, but we don't directly show the error!
It's even more annoying to debug when you consider --raw_output only
shows KUnit output by default, i.e. you need --raw_output=all to see it.
Whereas directly invoking the binary, Python will raise a
FileNotFoundError for us, which is a noisier but more clear.
Making this change requires
* splitting parameters like ['-m 256'] into ['-m', '256'] in
kunit/qemu_configs/*.py
* change [''] to [] in kunit/qemu_configs/*.py since otherwise
QEMU fails w/ 'Device needs media, but drive is empty'
* dropping explicit quoting of the kernel cmdline
* using shlex.quote() when we print what command we're running
so the user can copy-paste and run it

Before:
> Testing complete. Passed: 137, Failed: 0, Crashed: 0, Skipped: 36, Errors: 0
After:
> Testing complete. Ran 173 tests: passed: 137, skipped: 36
Even with our current set of statuses, the output is a bit verbose.
It could get worse in the future if we add more (e.g. timeout, kasan).
Let's only print the relevant ones.
I had previously been sympathetic to the argument that always
printing out all the statuses would make it easier to parse results.
But now we have commit acd8e8407b8f ("kunit: Print test statistics on
failure"), there are test counts printed out in the raw output.
We don't currently print out an overall total across all suites, but it
would be easy to add, if we see a need for that.

It may lead to kernel panic when execute the following testcase on mips:
# cd tools/testing/selftests/ftrace
# ./ftracetest test.d/kprobe/multiple_kprobes.tc
A preliminary analysis shows that the issue is related with
echo 1 > events/kprobes/enable
after add the 256 probe points.
In order to find the root cause, I want to verify which probe point has
problem, so it is necessary to save kprobe_events to test log.
With this patch, we can get the 256 probe points in the test log through
the following command:
# ./ftracetest test.d/kprobe/multiple_kprobes.tc -vvv -k

fexit_stress is attaching maximum allowed amount of fexit programs to
bpf_fentry_test1 kernel function, which is used by a bunch of other
parallel tests, thus pretty frequently interfering with their execution.
Given the test assumes nothing else is attaching to bpf_fentry_test1,
mark it serial.

This uses the newly added SEC("?foo") naming to disable autoload of

that loading fails and matches the returned error string from verifier.
This is similar to already existing verifier tests but provides coverage

In an effort to actually test the refcounting logic at runtime, add a
refcount_t member to prog_test_ref_kfunc and use it in selftests to
verify and test the whole logic more exhaustively.
The kfunc calls for prog_test_member do not require runtime refcounting,
as they are only used for verifier selftests, not during runtime
execution. Hence, their implementation now has a WARN_ON_ONCE as it is
not meant to be reachable code at runtime. It is strictly used in tests
triggering failure cases in the verifier. bpf_kfunc_call_memb_release is
called from map free path, since prog_test_member is embedded in map
value for some verifier tests, so we skip WARN_ON_ONCE for it.

non-offloaded h2
The host interfaces $h1 and $h2 don't have to be switchdev interfaces,
but due to the fact that we pass $tcflags which may have the value of
"skip_sw", we force $h2 to offload a drop rule for dst_ip, something
which it may not be able to do.
The selftest only wants to verify the hit count of this rule as a means
of figuring out whether the packet was received, so remove the $tcflags
for it and let it be done in software.

Some of the BPF selftests are failing when running with a rather bare
bones configuration based on tools/testing/selftests/bpf/config.
Specifically, we see a bunch of failures due to errno 95:
> test_attach_api:PASS:fentry_raw_skel_load 0 nsec
> libbpf: prog 'test_kprobe_manual': failed to attach: Operation not supported
> test_attach_api:FAIL:bpf_program__attach_kprobe_multi_opts unexpected error: -95
> 79 /6 kprobe_multi_test/attach_api_syms:FAIL
The cause of these is that CONFIG_FPROBE is missing. With this change we
add this configuration value to the BPF selftests config.

Convert the stats tests from spinning on the getsockopt to just check
getsockopt once when the Rx thread has received all the packets. The
actual completion of receiving the last packet forms a natural point
in time when the receiver is ready to call the getsockopt to check the
stats. In the previous version , we just span on the getsockopt until
we received the right answer. This could be forever or just getting
the "correct" answer by shear luck.
The pacing_on variable can now be dropped since all test can now
handle pacing properly.

Fix the reporting of failed tests as it was broken in several
ways. First, a failed test was reported as both failed and passed
messing up the count. Second, tests were not aborted after a failure
and could generate more "failures" messing up the count even
more. Third, the failure reporting from the application to the shell
script was wrong. It always reported pass. And finally, the handling
of the failures in the launch script was not correct.
Correct all this by propagating the failure up through the function
calls to a calling function that can abort the test. A receiver or
sender thread will mark the new variable in the test spec called fail,
if a test has failed. This is then picked up by the main thread when
everyone else has exited and this is then marked and propagated up to
the calling script.
Also add a summary function in the calling script so that a user
does not have to go through the sub tests to see if something has
failed.

veth after commit 726e2c5929de84 ("veth: Ensure eth header is in skb's

Also clean up the confusing naming. MIN_PKT_SIZE was really
MIN_ETH_PKT_SIZE and PKT_SIZE was both MIN_ETH_SIZE and the default
packet size called just PKT_SIZE. Make it consistent by using the

Also remove conflicting definitions from selftests. Some tests rely on
barrier_var() definition being nothing, those will still work as libbpf
does the #ifndef/#endif guarding for barrier() and barrier_var(),

In preparation to a following commit, add clang-format on and
clang-format off stanzas around constant definitions and the TEST_F_FORK
macro. This enables to keep aligned values, which is much more readable
than packed definitions.
Add other clang-format exceptions for FIXTURE() and
FIXTURE_VARIANT_ADD() declarations to force space before open brace,
which is reported by checkpatch.pl .

Update comments in memblock_free_*() functions to match the style used
in tests/alloc_*.c by rewording to make the expected outcome more apparent
and, if more than one memblock is involved, adding a visual of the
memory blocks.
If the comment has an extra column of spaces, remove the extra space at
the beginning of each line for consistency and to conform to Linux kernel
coding style.

check if udp packets and tcp packets are successfully delivered to user
space. If wrong udp packets are delivered, udpgso_bench_rx will exit

The function get_l3_stats() from the test hw_stats_l3.sh will be useful for
any test that wishes to work with L3 stats. Furthermore, it is easy to
generalize to other HW stats suites (for when such are added). Therefore,
move the code to lib.sh, rewrite it to have the same interface as the other
stats-collecting functions, and generalize to take the name of the HW stats
suite to collect as an argument.

The 'ping' utility is able to manage two kind of sockets (raw or icmp),
depending on the sysctl ping_group_range. By default, ping_group_range is
set to '1 0', which forces ping to use an ip raw socket.
Let's replay the ping tests by allowing 'ping' to use the ip icmp socket.
After the previous patch, ipv4 tests results are the same with both kinds
of socket. For ipv6, there are a lot a new failures (the previous patch
fixes only two cases).
