f99e413eb5 selftests/resctrl: Unmount resctrl FS if child fails to run benchmark
A child calls PARENT_EXIT() when it fails to run a benchmark to kill
the parent process. PARENT_EXIT() lacks unmount for the resctrl FS and
the parent won't be there to unmount it either after it gets killed.

Add the resctrl FS unmount also to PARENT_EXIT().

2d320b1029 selftests/resctrl: Don't leak buffer in fill_cache()
The error path in fill_cache() does return before the allocated buffer
is freed leaking the buffer.

The leak was introduced when fill_cache_read() started to return errors
in commit c7b607fa93 ("selftests/resctrl: Fix null pointer
dereference on open failed"), before that both fill functions always
returned 0.

Move free() earlier to prevent the mem leak.

a32e0834df ASoC: Updates for v6.6
Here's an initial batch of updates for ASoC for this release cycle.
 We've got a bunch of new drivers in here, a bit of core work from
 Morimoto-san and quite a lot of janitorial work.  There's several
 updates that pull in changes from other subsystems in order to build
 on them:
 
  - An adaptor to allow use of IIO DACs and ADCs in ASoC which pulls in
    some IIO changes.
  - Create a library function for intlog10() and use it in the NAU8825
    driver.
  - Include the ASoC tests, including the topology tests, in the default
    KUnit full test coverage.  This also involves enabling UML builds of
    ALSA since that's the default KUnit test environment which pulls in
    the addition of some stubs to the driver.
  - More factoring out from Morimoto-san.
  - Convert a lot of drivers to use the more modern maple tree register
    cache.
  - Support for AMD machines with MAX98388 and NAU8821, Cirrus Logic
    CS35L36, Intel AVS machines with ES8336 and RT5663 and NXP i.MX93.

e0606daeaa selftests: prctl: Add new prctl test for PR_SET_NAME
This patch will add the new test, which covers the prctl call
PR_SET_NAME command. The test tries to give a name using the PR_SET_NAME
call and then confirm it that it changed correctly by using  PR_GET_NAME.
It also tries to rename it with empty name.In the test PR_GET_NAME is
tested by passing null pointer to it and check its behaviour.

Similarly, ordering of MACVLAN creation and RIF creation will be relaxed

7c25ee819f torture: Cause mkinitrd.sh to indicate failure on compile errors
Currently, if the C program created by mkinitrd.sh has compile errors,
the errors are printed, but kvm.sh soldiers on, building kernels that
have init-less initrd setups.  The kernels then fail on boot when they
attempt to mount non-existent root filesystems.

This commit therefore improves user friendliness by making mkinitrd.sh
return non-zero exit status on compile errors, which in turn causes kvm.sh
to take an early exit, with the compile errors still clearly visible.

3666bccab4 selftests/xsk: reset NIC settings to default after running test suite
Currently, when running ZC test suite, after finishing first run of test
suite and then switching to busy-poll tests within xskxceiver, such
errors are observed:

libbpf: Kernel error message: ice: MTU is too large for linear frames and XDP prog does not support frags
1..26
libbpf: Kernel error message: Native and generic XDP can't be active at the same time
Error attaching XDP program
not ok 1 [xskxceiver.c:xsk_reattach_xdp:1568]: ERROR: 17/"File exists"

this is because test suite ends with 9k MTU and native xdp program being
loaded. Busy-poll tests start non-multi-buffer tests for generic mode.
To fix this, let us introduce bash function that will reset NIC settings
to default (e.g. 1500 MTU and no xdp progs loaded) so that test suite
can continue without interrupts. It also means that after busy-poll
tests NIC will have those default settings, whereas right now it is left
with 9k MTU and xdp prog loaded in native mode.

697604492b selftests/xsk: add invalid descriptor test for multi-buffer
Add a test that produces lots of nasty descriptors testing the corner
cases of the descriptor validation. Some of these descriptors are
valid and some are not as indicated by the valid flag. For a
description of all the test combinations, please see the code.

To stress the API, we need to be able to generate combinations of
descriptors that make little sense. A new verbatim mode is introduced
for the packet_stream to accomplish this. In this mode, all packets in
the packet_stream are sent as is. We do not try to chop them up into
frames that are of the right size that we know are going to work as we
would normally do. The packets are just written into the Tx ring even
if we know they make no sense.

17f1034dd7 selftests/xsk: transmit and receive multi-buffer packets
Add the ability to send and receive packets that are larger than the
size of a umem frame, using the AF_XDP /XDP multi-buffer
support. There are three pieces of code that need to be changed to
achieve this: the Rx path, the Tx path, and the validation logic.

Both the Rx path and Tx could only deal with a single fragment per
packet. The Tx path is extended with a new function called
pkt_nb_frags() that can be used to retrieve the number of fragments a
packet will consume. We then create these many fragments in a loop and
fill the N-1 first ones to the max size limit to use the buffer space
efficiently, and the Nth one with whatever data that is left. This
goes on until we have filled in at the most BATCH_SIZE worth of
descriptors and fragments. If we detect that the next packet would
lead to BATCH_SIZE number of fragments sent being exceeded, we do not
send this packet and finish the batch. This packet is instead sent in
the next iteration of BATCH_SIZE fragments.

For Rx, we loop over all fragments we receive as usual, but for every
descriptor that we receive we call a new validation function called
is_frag_valid() to validate the consistency of this fragment. The code
then checks if the packet continues in the next frame. If so, it loops
over the next packet and performs the same validation. once we have
received the last fragment of the packet we also call the function
is_pkt_valid() to validate the packet as a whole. If we get to the end
of the batch and we are not at the end of the current packet, we back
out the partial packet and end the loop. Once we get into the receive
loop next time, we start over from the beginning of that packet. This
so the code becomes simpler at the cost of some performance.

The validation function is_frag_valid() checks that the sequence and
packet numbers are correct at the start and end of each fragment.

example:

f589234e1a selftests: mptcp: userspace_pm: format subtests results in TAP
The current selftests infrastructure formats the results in TAP 13. This
version doesn't support subtests and only the end result of each
selftest is taken into account. It means that a single issue in a
subtest of a selftest containing multiple subtests forces the whole
selftest to be marked as failed. It also means that subtests results are
not tracked by CIs executing selftests.

MPTCP selftests run hundreds of various subtests. It is then important
to track each of them and not one result per selftest.

It is particularly interesting to do that when validating stable kernels
with the last version of the test suite: tests might fail because a
feature is not supported but the test didn't skip that part. In this
case, if subtests are not tracked, the whole selftest will be marked as
failed making the other subtests useless because their results are
ignored.

This patch formats subtests results in TAP in userspace_pm.sh selftest.

ce99025736 selftests: mptcp: diag: format subtests results in TAP
The current selftests infrastructure formats the results in TAP 13. This
version doesn't support subtests and only the end result of each
selftest is taken into account. It means that a single issue in a
subtest of a selftest containing multiple subtests forces the whole
selftest to be marked as failed. It also means that subtests results are
not tracked by CIs executing selftests.

MPTCP selftests run hundreds of various subtests. It is then important
to track each of them and not one result per selftest.

It is particularly interesting to do that when validating stable kernels
with the last version of the test suite: tests might fail because a
feature is not supported but the test didn't skip that part. In this
case, if subtests are not tracked, the whole selftest will be marked as
failed making the other subtests useless because their results are
ignored.

This patch formats subtests results in TAP in diag.sh selftest.

In this selftest and before starting each subtest, the 'reset' function
is called. We can then check if the previous test has passed, failed or
has been skipped from there.

d8463d8165 selftests: mptcp: userspace_pm: reduce dup code around printf
In this selftest, "printf" is always used with "stdbuf".

With a new helper, it is possible to call "stdbuf" only from one place.
This makes the code a bit clearer to read.

e198ad7592 selftests: mptcp: userspace_pm: uniform results printing
There are a few reasons to do that:

- When the tabs are not printed as 8 spaces, some results were not
  properly aligned

- Some lines printing the test name were very long due to the use of a
  lot of spaces/tabs at the end and stdbuf at the beginning.

- To reduce duplicated code, e.g. to print what has failed and set the
  status

But by centralising how the test results are printed, this also prepares
future commits to avoid more duplicated code and ease the tracking of
the different subtests.

8320b1387a selftests: mptcp: userspace_pm: fix shellcheck warnings
shellcheck recently helped to find an issue where a wrong variable name
was used. It is then good to fix the other harmless issues in order to
spot "real" ones later.

Here, three categories of warnings are ignored:

- SC2317: Command appears to be unreachable. The cleanup() function is
  invoke indirectly via the EXIT trap.

- SC2034: Variable appears unused. The check_expected_one() function
  takes the name of the variable in argument but it ends up reading the
  content: indirect usage.

- SC2086: Double quote to prevent globbing and word splitting. This is
  recommended but the current usage is correct and there is no need to
  do all these modifications to be compliant with this rule.

One error has been fixed with SC2181: Check exit code directly with e.g.
'if ! mycmd;', not indirectly with $?.

No more tests were executed after a failure but it is still interesting
to get results for all the tests to better understand what's still OK
and what's not after a modification.

Now we only exit earlier if the two connections cannot be established.
