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.

The disable_async paths of iaa_compress/decompress() don't free idxd
descriptors in the async_disable case. Currently this only happens in
the testcases where req->dst is set to null. Add a test to free them
in those paths.

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.

The function dh_is_pubkey_valid was added to for FIPS but it was
only partially conditional to fips_enabled.
In particular, the first test in the function relies on the last
test to work properly, but the last test is only run in FIPS mode.
Fix this inconsistency by making the whole function conditional
on fips_enabled.

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.
v4:
- rebase on top of Mickael's vfork() changes
v3: https://lore.kernel.org/all/20240220192235.2953484-1-kuba@kernel.org/
- combine multiple series
- change to "list of expected failures" rather than SKIP()-like handling
v2: https://lore.kernel.org/all/20240216002619.1999225-1-kuba@kernel.org/

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.

ksft_test_result_code()
According to the spec we should always print a # if we add
a diagnostic message. Having the caller pass in the new line
as part of diagnostic message makes handling this a bit

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:

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.

those parts of the message.

We always use skip in combination with exit_code being 0

Store the right KSFT_* code in exit_code directly.

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 63e6b2a42342 ("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 369130b63178
("selftests: Enhance kselftest_harness.h to print which assert failed").
Replace spaces with tabs in one line of __TEST_F_IMPL().

This has the effect of creating a new test process for either TEST_F()

Qualcomm ARM64 DeviceTree updates for v6.9
Four variants of Samsung Galaxy Core Prime and Grand Prime, built on
MSM8916, and the Hardware Development Kit (HDK) for SM8550, are
introduced.
On X Elite audio and compute remoteprocs, IPCC, PCIe, AOSS QMP, SMP2P,
TCSR, USB, display, audio, and soundwire support is introduced, and
enabled across the CRD and QCP devices.
For SM8650 PCIe controllers are moved to GIC-ITS and msi-map-mask is
defined. Missing qlink-logging reserved-memory region is added for the
modem remoteproc. FastRPC compute contexts are marked dma-coherent.
Audio, USB Type-C and PM8010 support is introduced across MTP and QRD
devices.
GPU cooling devices are hooked up across MSM8916, MSM8939, SC8180X,
SDM630, SDM845, SM6115, SM8150, SM8250, SM8350, and SM8550.
UFS PHY clocks are corrected across MSM8996, MSM8998, SC8180X, SC8280XP,

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
are added. On SM7125 UFS support is added.
On Fairphone FP4, on SM7225, display and GPU are enabled, and firmware
paths are corrected.
SM8150 PCIe controller definitions are corrected.
As with SM8650, the SM8550 the fastrpc compute contexts are marked
dm-coherent, and PCIe controllers are moved to use GIC-ITS. The UFS
controller frequency definition is moved to the generic opp-table.
Touchscreen is enabled on the QRD device.
As usual, a variety of smaller cleanups and corrections to match
DeviceTree bindings and style guidelines are introduced across the
various files.

Commit 358e76fd613a ("drm/sun4i: hdmi: Consolidate atomic_check and
mode_valid") added a call to drm_atomic_get_new_connector_state() but
didn't include drm_atomic.h which defines it.
On some configuration, this leads to a build failure, presumably because
in the common case the header gets included by an intermediate header
but it isn't always the case.
Let's add a proper include.

====================
net: phy: qcom: qca808x: fill in possible_interfaces
QCA808x does not currently fill in the possible_interfaces.
This leads to Phylink not being aware that it supports 2500Base-X as well
so in cases where it is connected to a DSA switch like MV88E6393 it will
limit that port to phy-mode set in the DTS.
That means that if SGMII is used you are limited to 1G only while if
2500Base-X was set you are limited to 2.5G only.
Populating the possible_interfaces fixes this.
Changes in v2:
* Get rid of the if/else by Russels suggestion in the helper

Currently QCA808x driver does not fill the possible_interfaces.
2.5G QCA808x support SGMII and 2500Base-X while 1G model only supports
SGMII, so fill the possible_interfaces accordingly.

There are 2 versions of QCA808x, one 2.5G capable and one 1G capable.
Currently, this matter only in the .get_features call however, it will
be required for filling supported interface modes so lets add a helper
that can be reused.

It is now possible to disable BQL, but that causes the cpsw driver to break:
drivers/net/ethernet/ti/am65-cpsw-nuss.c:297:28: error: no member named 'dql' in 'struct netdev_queue'
297 | dql_avail(&netif_txq->dql),
There is already a helper function in net/sch_generic.h that could
be used to help here. Move its implementation into the common
linux/netdevice.h along with the other bql interfaces and change
both users over to the new interface.

====================
ipv6: lockless accesses to devconf
- First patch puts in a cacheline_group the fields used in fast paths.
- Annotate all data races around idev->cnf fields.
- Last patch in this series removes RTNL use for RTM_GETNETCONF dumps.
v3: addressed Jakub Kicinski feedback in addrconf_disable_ipv6()
Added tags from Jiri and Florian.
v2: addressed Jiri Pirko feedback
- Added "ipv6: addrconf_disable_ipv6() optimizations"
and "ipv6: addrconf_disable_policy() optimization"

1) inet6_netconf_dump_devconf() can run under RCU protection
instead of RTNL.
2) properly return 0 at the end of a dump, avoiding an
an extra recvmsg() system call.
3) Do not use inet6_base_seq() anymore, for_each_netdev_dump()
has nice properties. Restarting a GETDEVCONF dump if a device has
been added/removed or if net->ipv6.dev_addr_genid has changed is moot.
