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

bpf_fentry_test1 kernel function, which is used by a bunch of other

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

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.

Also clean up the confusing naming. MIN_PKT_SIZE was really
