380cb2f4df selftests/powerpc: Fix fpu_signal failures
My recent commit e5d00aaac6 ("selftests/powerpc: Check all FPRs in
fpu_preempt") inadvertently broke the fpu_signal test.

It needs to take into account that fpu_preempt now loads 32 FPRs, so
enlarge darray.

Also use the newly added randomise_darray() to properly randomise darray.

Finally the checking done in signal_fpu_sig() needs to skip checking
f30/f31, because they are used as scratch registers in check_all_fprs(),
called by preempt_fpu(), and so could hold other values when the signal
is taken.

642b02b45d ALSA: hda: optimize the probe codec process
In azx_probe_codecs function, when bus->codec_mask is becomes to 0(no codecs),
execute azx_init_chip, bus->codec_mask will be initialized to a value again,
this causes snd_hda_codec_new function to run, the process is as follows:
-->snd_hda_codec_new
-->snd_hda_codec_device_init
-->snd_hdac_device_init---snd_hdac_read_parm(...AC_PAR_VENDOR_ID) 2s
		       ---snd_hdac_read_parm(...AC_PAR_VENDOR_ID) 2s
		       ---snd_hdac_read_parm(...AC_PAR_SUBSYSTEM_ID) 2s
		       ---snd_hdac_read_parm(...AC_PAR_REV_ID) 2s
		       ---snd_hdac_read_parm(...AC_PAR_NODE_COUNT) 2s
when no codecs, read communication is error, each command will be polled for
2 second, a total of 10s, it is easy to some problem.
like this:

76f06cbd7b Merge branch 'netdevsim-link'
David Wei says:

====================
netdevsim: link and forward skbs between ports

This patchset adds the ability to link two netdevsim ports together and
forward skbs between them, similar to veth. The goal is to use netdevsim
for testing features e.g. zero copy Rx using io_uring.

This feature was tested locally on QEMU, and a selftest is included.

I ran netdev selftests CI style and all tests but the following passed:
- gro.sh
- l2tp.sh
- ip_local_port_range.sh

gro.sh fails because virtme-ng mounts as read-only and it tries to write
to log.txt. This issue was reported to virtme-ng upstream.

l2tp.sh and ip_local_port_range.sh both fail for me on net-next/main as
well.

9eb95228a7 netdevsim: forward skbs from one connected port to another
Forward skbs sent from one netdevsim port to its connected netdevsim
port using dev_forward_skb, in a spirit similar to veth.

Add a tx_dropped variable to struct netdevsim, tracking the number of
skbs that could not be forwarded using dev_forward_skb().

The xmit() function accessing the peer ptr is protected by an RCU read
critical section. The rcu_read_lock() is functionally redundant as since
v5.0 all softirqs are implicitly RCU read critical sections; but it is
useful for human readers.

If another CPU is concurrently in nsim_destroy(), then it will first set
the peer ptr to NULL. This does not affect any existing readers that
dereferenced a non-NULL peer. Then, in unregister_netdevice(), there is
a synchronize_rcu() before the netdev is actually unregistered and
freed. This ensures that any readers i.e. xmit() that got a non-NULL
peer will complete before the netdev is freed.

Any readers after the RCU_INIT_POINTER() but before synchronize_rcu()
will dereference NULL, making it safe.

The codepath to nsim_destroy() and nsim_create() takes both the newly
added nsim_dev_list_lock and rtnl_lock. This makes it safe with
concurrent calls to linking two netdevsims together.

cdb083e73d crypto: iaa - Fix comp/decomp delay statistics
The comp/decomp delay statistics currently have no callers; somehow
they were dropped during refactoring. There originally were also two
sets, one for the async algorithm, the other for the synchronous
version. Because the synchronous algorithm was dropped, one set should
be removed. To keep it consistent with the rest of the stats, and
since there's no ambiguity, remove the acomp/adecomp versions.  Also
add back the callers.

2beb81fbf0 crypto: remove CONFIG_CRYPTO_STATS
Remove support for the "Crypto usage statistics" feature
(CONFIG_CRYPTO_STATS).  This feature does not appear to have ever been
used, and it is harmful because it significantly reduces performance and
is a large maintenance burden.

Covering each of these points in detail:

1. Feature is not being used

Since these generic crypto statistics are only readable using netlink,
it's fairly straightforward to look for programs that use them.  I'm
unable to find any evidence that any such programs exist.  For example,
Debian Code Search returns no hits except the kernel header and kernel
code itself and translations of the kernel header:
https://codesearch.debian.net/search?q=CRYPTOCFGA_STAT&literal=1&perpkg=1

The patch series that added this feature in 2018
(https://lore.kernel.org/linux-crypto/1537351855-16618-1-git-send-email-clabbe@baylibre.com/)
said "The goal is to have an ifconfig for crypto device."  This doesn't
appear to have happened.

It's not clear that there is real demand for crypto statistics.  Just
because the kernel provides other types of statistics such as I/O and
networking statistics and some people find those useful does not mean
that crypto statistics are useful too.

Further evidence that programs are not using CONFIG_CRYPTO_STATS is that
it was able to be disabled in RHEL and Fedora as a bug fix
(https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-9/-/merge_requests/2947).

Even further evidence comes from the fact that there are and have been
bugs in how the stats work, but they were never reported.  For example,
before Linux v6.7 hash stats were double-counted in most cases.

There has also never been any documentation for this feature, so it
might be hard to use even if someone wanted to.

2. CONFIG_CRYPTO_STATS significantly reduces performance

Enabling CONFIG_CRYPTO_STATS significantly reduces the performance of
the crypto API, even if no program ever retrieves the statistics.  This
primarily affects systems with large number of CPUs.  For example,
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2039576 reported
that Lustre client encryption performance improved from 21.7GB/s to
48.2GB/s by disabling CONFIG_CRYPTO_STATS.

It can be argued that this means that CONFIG_CRYPTO_STATS should be
optimized with per-cpu counters similar to many of the networking
counters.  But no one has done this in 5+ years.  This is consistent
with the fact that the feature appears to be unused, so there seems to
be little interest in improving it as opposed to just disabling it.

It can be argued that because CONFIG_CRYPTO_STATS is off by default,
performance doesn't matter.  But Linux distros tend to error on the side
of enabling options.  The option is enabled in Ubuntu and Arch Linux,
and until recently was enabled in RHEL and Fedora (see above).  So, even
just having the option available is harmful to users.

3. CONFIG_CRYPTO_STATS is a large maintenance burden

There are over 1000 lines of code associated with CONFIG_CRYPTO_STATS,
spread among 32 files.  It significantly complicates much of the
implementation of the crypto API.  After the initial submission, many
fixes and refactorings have consumed effort of multiple people to keep
this feature "working".  We should be spending this effort elsewhere.

e2d890afba Merge branch 'selftests-xfail'
Jakub Kicinski says:

====================
selftests: kselftest_harness: support using xfail

When running selftests for our subsystem in our CI we'd like all
tests to pass. Currently some tests use SKIP for cases they
expect to fail, because the kselftest_harness limits the return
codes to pass/fail/skip. XFAIL which would be a great match
here cannot be used.

Remove the no_print handling and use vfork() to run the test in
a different process than the setup. This way we don't need to
pass "failing step" via the exit code. Further clean up the exit
codes so that we can use all KSFT_* values. Rewrite the result
printing to make handling XFAIL/XPASS easier. Support tests
declaring combinations of fixture + variant they expect to fail.

Merge plan is to put it on top of -rc6 and merge into net-next.
That way others should be able to pull the patches without
any networking changes.

2709473c93 selftests: kselftest_harness: support using xfail
Currently some tests report skip for things they expect to fail
e.g. when given combination of parameters is known to be unsupported.
This is confusing because in an ideal test environment and fully
featured kernel no tests should be skipped.

Selftest summary line already includes xfail and xpass counters,
e.g.:

  Totals: pass:725 fail:0 xfail:0 xpass:0 skip:0 error:0

but there's no way to use it from within the harness.

Add a new per-fixture+variant combination list of test cases
we expect to fail.

According to the spec we should always print a # if we add

as part of diagnostic message makes handling this a bit

732e203528 selftests: kselftest_harness: print test name for SKIP
Jakub points out that for parsers it's rather useful to always
have the test name on the result line. Currently if we SKIP
(or soon XFAIL or XPASS), we will print:

ok 17 # SKIP SCTP doesn't support IP_BIND_ADDRESS_NO_PORT

     ^
     no test name

Always print the test name.
KTAP format seems to allow or even call for it, per:

fa1a53d836 selftests: kselftest: add ksft_test_result_code(), handling all exit codes
For generic test harness code it's more useful to deal with exit
codes directly, rather than having to switch on them and call
the right ksft_test_result_*() helper. Add such function to kselftest.h.

Note that "directive" and "diagnostic" are what ktap docs call
those parts of the message.

796a344fa4 selftests: kselftest_harness: use exit code to store skip
We always use skip in combination with exit_code being 0
(KSFT_PASS). This are basic KSFT / KTAP semantics.
Store the right KSFT_* code in exit_code directly.

This makes it easier to support tests reporting other
extended KSFT_* codes like XFAIL / XPASS.

0710a1a73f selftests/harness: Merge TEST_F_FORK() into TEST_F()
Replace Landlock-specific TEST_F_FORK() with an improved TEST_F() which
brings four related changes:

Run TEST_F()'s tests in a grandchild process to make it possible to
drop privileges and delegate teardown to the parent.

Compared to TEST_F_FORK(), simplify handling of the test grandchild
process thanks to vfork(2), and makes it generic (e.g. no explicit
conversion between exit code and _metadata).

Compared to TEST_F_FORK(), run teardown even when tests failed with an
assert thanks to commit 63e6b2a423 ("selftests/harness: Run TEARDOWN
for ASSERT failures").

Simplify the test harness code by removing the no_print and step fields
which are not used.  I added this feature just after I made
kselftest_harness.h more broadly available but this step counter
remained even though it wasn't needed after all. See commit 369130b631
("selftests: Enhance kselftest_harness.h to print which assert failed").

Replace spaces with tabs in one line of __TEST_F_IMPL().

 PCI MSI interrupts are wired up across SM8150, SM8250, SM8350, SM8450,
 SM8550, SM8650, SC7280, and SC8180X
 
 On IPQ6018 QUP5 I2C, tsens sand thermal zones are defined. The Inline
 Crypto Engine (ICE) is enabled for IPQ9574.
 
 On MSM8953 the GPU and its IOMMU is introduced, the reset for the
 display subsystem is also wired up.
 
 VLS CLAMP registers are specified for USB3 PHYs on MSM8998, QCM2290, and
 SM6115.
 
 USB Type-C port management is enabled on QRB4210 RB2.
 
 On the SA8295P ADP the MAX20411 regulator powering the GPU rails is
 introduced and the GPU is enabled. The first PCI instance on SA8540P
 Ride is disabled for now, as a fix for the interrupt storm produced here
 has not been presented.
 
 On SA8775P the firmware memory map has changed and is updated. Safety
 IRQ is added to the Ethernet controller.
 
 On SC7180 UFS support is introduced and the cros-ec-spi is marked as
 wakeup source.
 
 For SC7280 capacity and DPC properties are added, cryptobam definition
 is improved to work in more firmware environments, more Chrome-specific
 properties are moved out from main dtsi, and cros-ec-spi is maked as a
 wakeup source. Slimbus definition is added to the platform.
 
 A missing reserved-memory range is added to Fairphone FP5, PMIC GLINK
 and Venus are enabled. LEDs are introduced and voltage settings
 corrected on the QCM6490 IDP, and RB3gen2 sees the same voltage changes
 and GCC protected clocks are introduced to make the board boot properly.
 
 RPMh sleep stats and a variety of cleanups and fixes are introduced for
 SC8180X.
 
 On SC8280XP the additional tsens instances are introduced. Camera
 Subsystem and Camera Control Interface (CCI) are added. PMIC die-temp
 vadc channels are introduced on the CRD, to allow ADC channels to be
 tied to the shared PMIC temp-alarms, to actually report temperature.
 
 On SDM630 USB QMP PHY support is introduced and enabled on the Inforce
 IFC6560 board. On the various Sony Xperia XA2 variants WLED is enabled
 and configured.
 
 On SM6350 display subsystem interconnects and tsens-based thermal zones

Justin Chen says:

====================
Support for ASP 2.2 and optimizations

ASP 2.2 adds some power savings during low power modes.

Also make various improvements when entering low power modes and
reduce MDIO traffic by hooking up interrupts.

4688f4f41c net: bcmasp: Keep buffers through power management
There is no advantage of freeing and re-allocating buffers through
suspend and resume. This waste cycles and makes suspend/resume time
longer. We also open ourselves to failed allocations in systems with
heavy memory fragmentation.

1d472eb5b6 net: bcmasp: Add support for ASP 2.2
ASP 2.2 improves power savings during low power modes.

A new register was added to toggle to a slower clock during low
power modes.

EEE was broken for ASP 2.0/2.1. A HW workaround was added for
ASP 2.2 that requires toggling a chicken bit.
