Pull x86 sgx updates from Dave Hansen:
"The biggest deal in this series is support for a new hardware feature
that allows enclaves to detect and mitigate single-stepping attacks.
There's also a minor performance tweak and a little piece of the
kmap_atomic() -> kmap_local() transition.
Summary:
- Introduce a new SGX feature (Asynchrounous Exit Notification) for
bare-metal enclaves and KVM guests to mitigate single-step attacks
- Increase batching to speed up enclave release
- Replace kmap/kunmap_atomic() calls"

Pull cxl updates from Dan Williams:
"Compute Express Link (CXL) updates for 6.2.
While it may seem backwards, the CXL update this time around includes
some focus on CXL 1.x enabling where the work to date had been with
CXL 2.0 (VH topologies) in mind.
First generation CXL can mostly be supported via BIOS, similar to DDR,
however it became clear there are use cases for OS native CXL error
handling and some CXL 3.0 endpoint features can be deployed on CXL 1.x
hosts (Restricted CXL Host (RCH) topologies). So, this update brings
RCH topologies into the Linux CXL device model.
In support of the ongoing CXL 2.0+ enabling two new core kernel
facilities are added.
One is the ability for the kernel to flag collisions between userspace
access to PCI configuration registers and kernel accesses. This is
brought on by the PCIe Data-Object-Exchange (DOE) facility, a hardware
mailbox over config-cycles.
The other is a cpu_cache_invalidate_memregion() API that maps to
wbinvd_on_all_cpus() on x86. To prevent abuse it is disabled in guest
VMs and architectures that do not support it yet. The CXL paths that
need it, dynamic memory region creation and security commands (erase /
unlock), are disabled when it is not present.
As for the CXL 2.0+ this cycle the subsystem gains support Persistent
Memory Security commands, error handling in response to PCIe AER
notifications, and support for the "XOR" host bridge interleave
algorithm.
Summary:
- Add the cpu_cache_invalidate_memregion() API for cache flushing in
response to physical memory reconfiguration, or memory-side data
invalidation from operations like secure erase or memory-device
unlock.
- Add a facility for the kernel to warn about collisions between
kernel and userspace access to PCI configuration registers
- Add support for Restricted CXL Host (RCH) topologies (formerly CXL
1.1)
- Add handling and reporting of CXL errors reported via the PCIe AER
mechanism
- Add support for CXL Persistent Memory Security commands
- Add support for the "XOR" algorithm for CXL host bridge interleave
- Rework / simplify CXL to NVDIMM interactions
- Miscellaneous cleanups and fixes"

Currently the KTAP specification says that a test result line is
<result> <number> [<description>][ # [<directive>] [<diagnostic data>]]
and the description of a test can be "any sequence of words
(can't include #)" which specifies that there may be more than
one word but does not specify anything other than those words
which might be used to separate the words which probably isn't
what we want. Given that practically we have tests using a range
of separators for words including combinations of spaces and
combinations of other symbols like underscores or punctuation
let's just clarify that the description can contain any character
other than # (marking the start of the directive/diagnostic) or
newline (marking the end of this test result).

Use macros, VISIBLE_IF_KUNIT and EXPORT_SYMBOL_IF_KUNIT, to allow
static symbols to be conditionally set to be visible during
apparmor_policy_unpack_test, which removes the need to include the testing
file in the implementation file.
Change the namespace of the symbols that are now conditionally visible (by
adding the prefix aa_) to avoid confusion with symbols of the same name.
Allow the test to be built as a module and namespace the module name from
policy_unpack_test to apparmor_policy_unpack_test to improve clarity of
the module name.

Currently, kunit_parser.py is stripping all leading whitespace to make
parsing easier. But this means we can't accurately show kernel output
for failing tests or when the kernel crashes.
Embarassingly, this affects even KUnit's own output, e.g.
[13:40:46] Expected 2 + 1 == 2, but
[13:40:46] 2 + 1 == 3 (0x3)
[13:40:46] not ok 1 example_simple_test
[13:40:46] [FAILED] example_simple_test
After this change, here's what the output in context would look like
[13:40:46] =================== example (4 subtests) ===================
[13:40:46] # example_simple_test: initializing
[13:40:46] # example_simple_test: EXPECTATION FAILED at lib/kunit/kunit-example-test.c:29

[13:40:46] ===================== [FAILED] example =====================
This example shows one minor cosmetic defect this approach has.
The test counts lines prevent us from dedenting the suite-level output.
But at the same time, any form of non-KUnit output would do the same

The "How Do I Use This" section of index.rst and "Next Steps" section of
start.rst were just copies of the table of contents, and therefore
weren't really useful either when looking a sphinx generated output
(which already had the TOC visible) or when reading the source (where
it's just a list of files that ls could give you).
Instead, provide a small number of concrete next steps, and a bit more
description about what the pages contain.
This also removes the broken reference to 'tips.rst', which was

We print the "test log" on failure.
This is meant to be all the kernel output that happened during the test.
But we also include the special KTAP lines in it, which are often
redundant.
E.g. we include the "not ok" line in the log, right before we print
that the test case failed...

Change KUnit test output to better comply with KTAP v1 specifications
found here: https://kernel.org/doc/html/latest/dev-tools/ktap.html.
1) Use "KTAP version 1" instead of "TAP version 14" as test output header
2) Remove '-' between test number and test name on test result lines
2) Add KTAP version lines to each subtest header as well
Note that the new KUnit output still includes the “# Subtest” line now
located after the KTAP version line. This does not completely match the
KTAP v1 spec but since it is classified as a diagnostic line, it is not
expected to be disruptive or break any existing parsers. This
“# Subtest” line comes from the TAP 14 spec
(https://testanything.org/tap-version-14-specification.html) and it is
used to define the test name before the results.
Original output:
TAP version 14
1..1
# Subtest: kunit-test-suite

the KTAP version 1 specification format found here:
https://kernel.org/doc/html/latest/dev-tools/ktap.html. Ensure the parser
is able to parse tests with the original KUnit test output format as
well.
KUnit parser now accepts any of the following test output formats:
Original KUnit test output format:
TAP version 14
1..1
# Subtest: kunit-test-suite
1..3
ok 1 - kunit_test_1
ok 2 - kunit_test_2
ok 3 - kunit_test_3
# kunit-test-suite: pass:3 fail:0 skip:0 total:3
# Totals: pass:3 fail:0 skip:0 total:3
ok 1 - kunit-test-suite
KTAP version 1 test output format:
KTAP version 1
1..1
KTAP version 1
1..3
ok 1 kunit_test_1
ok 2 kunit_test_2
ok 3 kunit_test_3
ok 1 kunit-test-suite
New KUnit test output format (changes made in the next patch of
this series):
KTAP version 1
1..1
KTAP version 1
# Subtest: kunit-test-suite
1..3
ok 1 kunit_test_1

Use the newly-added function kunit_get_current_test() instead of
accessing current->kunit_test directly. This function uses a static key
to return more quickly when KUnit is enabled, but no tests are actively
running. There should therefore be a negligible performance impact to
enabling the slub KUnit tests.
Other than the performance improvement, this should be a no-op.

In order to detect if a KUnit test is running, and to access its
context, the 'kunit_test' member of the current task_struct is used.
Usually, this is accessed directly or via the kunit_fail_current_task()
function.
In order to speed up the case where no test is running, add a wrapper,
kunit_get_current_test(), which uses the static key to fail early.
Equally, Speed up kunit_fail_current_test() by using the static key.
This should make it convenient for code to call this
unconditionally in fakes or error paths, without worrying that this will
slow the code down significantly.
If CONFIG_KUNIT=n (or m), this compiles away to nothing. If
CONFIG_KUNIT=y, it will compile down to a NOP (on most architectures) if
no KUnit test is currently running.
Note that kunit_get_current_test() does not work if KUnit is built as a
module. This mirrors the existing restriction on kunit_fail_current_test().
Note that the definition of kunit_fail_current_test() still wraps an
empty, inline function if KUnit is not built-in. This is to ensure that
the printf format string __attribute__ will still work.
Also update the documentation to suggest users use the new
kunit_get_current_test() function, update the example, and to describe
the behaviour when KUnit is disabled better.

KUnit does a few expensive things when enabled. This hasn't been a
problem because KUnit was only enabled on test kernels, but with a few
people enabling (but not _using_) KUnit on production systems, we need a
runtime way of handling this.
Provide a 'kunit_running' static key (defaulting to false), which allows
us to hide any KUnit code behind a static branch. This should reduce the
performance impact (on other code) of having KUnit enabled to a single
NOP when no tests are running.
Note that, while it looks unintuitive, tests always run entirely within
__kunit_test_suites_init(), so it's safe to decrement the static key at
the end of this function, rather than in __kunit_test_suites_exit(),
which is only there to clean up results in debugfs.

When --raw_output is set (to any value), we don't actually parse the
test results. So asking to print the test results as json doesn't make
sense.
We internally create a fake test with one passing subtest, so --json
would actually print out something misleading.
This patch:
* Rewords the flag descriptions so hopefully this is more obvious.
* Also updates --raw_output's description to note the default behavior
is to print out only "KUnit" results (actually any KTAP results)
* also renames and refactors some related logic for clarity (e.g.
test_result => test, it's a kunit_parser.Test object).
Notably, this patch does not make it an error to specify --json and
--raw_output together. This is an edge case, but I know of at least one
wrapper around kunit.py that always sets --json. You'd never be able to
use --raw_output with that wrapper.

These macros exist because passing an initializer list to other macros
is hard.
The goal of these macros is to generate a line like
struct $ASSERT_TYPE __assertion = $APPROPRIATE_INITIALIZER;
e.g.
struct kunit_unary_assertion __assertion = {
.condition = "foo()",
.expected_true = true
};
But the challenge is you can't pass `{.condition=..., .expect_true=...}`
as a macro argument, since the comma means you're actually passing two
arguments, `{.condition=...` and `.expect_true=....}`.
So we'd made custom macros for each different initializer-list shape.
But we can work around this with the following generic macro
#define KUNIT_INIT_ASSERT(initializers...) { initializers }
Note: this has the downside that we have to rename some macros arguments
to not conflict with the struct field names (e.g. `expected_true`).
It's a bit gross, but probably worth reducing the # of macros.

Before, only the destructor from TCP request sock in IPv4 was called
even if the subflow was IPv6.
It is important to use the right destructor to avoid memory leaks with
some advanced IPv6 features, e.g. when the request socks contain
specific IPv6 options.

tcp_request_sock_ops structure is specific to IPv4. It should then not
be used with MPTCP subflows on top of IPv6.
For example, it contains the 'family' field, initialised to AF_INET.
This 'family' field is used by TCP FastOpen code to generate the cookie
but also by TCP Metrics, SELinux and SYN Cookies. Using the wrong family
will not lead to crashes but displaying/using/checking wrong things.
Note that 'send_reset' callback from request_sock_ops structure is used
in some error paths. It is then also important to use the correct one
for IPv4 or IPv6.
The slab name can also be different in IPv4 and IPv6, it will be used
when printing some log messages. The slab pointer will anyway be the
same because the object size is the same for both v4 and v6. A
BUILD_BUG_ON() has also been added to make sure this size is the same.

To ease the maintenance, it is often recommended to avoid having #ifdef
preprocessor conditions.
Here the section related to CONFIG_MPTCP was quite short but the next
commit needs to add more code around. It is then cleaner to move
specific MPTCP code to functions located in net/mptcp directory.
Now that mptcp_subflow_request_sock_ops structure can be static, it can
also be marked as "read only after init".

Recently, a customer reported that from their container whose
net namespace is different to the host's init_net, they can't set
the container's net.sctp.rto_max to any value smaller than
init_net.sctp.rto_min.
For instance,
Host:
sudo sysctl net.sctp.rto_min
net.sctp.rto_min = 1000
Container:
echo 100 > /mnt/proc-net/sctp/rto_min
echo 400 > /mnt/proc-net/sctp/rto_max
echo: write error: Invalid argument
This is caused by the check made from this'commit 4f3fdf3bc59c
("sctp: add check rto_min and rto_max in sysctl")'
When validating the input value, it's always referring the boundary
value set for the init_net namespace.
Having container's rto_max smaller than host's init_net.sctp.rto_min
does make sense. Consider that the rto between two containers on the
same host is very likely smaller than it for two hosts.
So to fix this problem, as suggested by Marcelo, this patch makes the
extra pointers of rto_min, rto_max, pf_retrans, and ps_retrans point
to the corresponding variables from the newly created net namespace while
the new net namespace is being registered in sctp_sysctl_net_register.

TX/RX callback handlers (ntb_netdev_tx_handler(),
ntb_netdev_rx_handler()) can be called in interrupt
context via the DMA framework when the respective
DMA operations have completed. As such, any calls
by these routines to free skb's, should use the
interrupt context safe dev_kfree_skb_any() function.
Previously, these callback handlers would call the
interrupt unsafe version of dev_kfree_skb(). This has
not presented an issue on Intel IOAT DMA engines as
that driver utilizes tasklets rather than a hard
interrupt handler, like the AMD PTDMA DMA driver.
On AMD systems, a kernel WARNING message is
encountered, which is being issued from
skb_release_head_state() due to in_hardirq()
being true.
Besides the user visible WARNING from the kernel,
the other symptom of this bug was that TCP/IP performance
across the ntb_netdev interface was very poor, i.e.
approximately an order of magnitude below what was
expected. With the repair to use dev_kfree_skb_any(),
kernel WARNINGs from skb_release_head_state() ceased
and TCP/IP performance, as measured by iperf, was on
par with expected results, approximately 20 Gb/s on
AMD Milan based server. Note that this performance
is comparable with Intel based servers.

Pull timer updates from Thomas Gleixner:
"Updates for timers, timekeeping and drivers:
Core:
- The timer_shutdown[_sync]() infrastructure:
Tearing down timers can be tedious when there are circular
dependencies to other things which need to be torn down. A prime
example is timer and workqueue where the timer schedules work and
the work arms the timer.
What needs to prevented is that pending work which is drained via
destroy_workqueue() does not rearm the previously shutdown timer.
Nothing in that shutdown sequence relies on the timer being
functional.
The conclusion was that the semantics of timer_shutdown_sync()
should be:
- timer is not enqueued
- timer callback is not running
- timer cannot be rearmed
Preventing the rearming of shutdown timers is done by discarding
rearm attempts silently.
A warning for the case that a rearm attempt of a shutdown timer is
detected would not be really helpful because it's entirely unclear
how it should be acted upon. The only way to address such a case is
to add 'if (in_shutdown)' conditionals all over the place. This is
error prone and in most cases of teardown not required all.
- The real fix for the bluetooth HCI teardown based on
timer_shutdown_sync().
A larger scale conversion to timer_shutdown_sync() is work in
progress.
- Consolidation of VDSO time namespace helper functions
- Small fixes for timer and timerqueue
Drivers:
- Prevent integer overflow on the XGene-1 TVAL register which causes
an never ending interrupt storm.
- The usual set of new device tree bindings
- Small fixes and improvements all over the place"

Pull x86 cleanups from Thomas Gleixner:
"A set of x86 cleanups:
- Rework the handling of x86_regset for 32 and 64 bit.
The original implementation tried to minimize the allocation size
with quite some hard to understand and fragile tricks. Make it
robust and straight forward by separating the register enumerations
for 32 and 64 bit completely.
- Add a few missing static annotations
- Remove the stale unused setup_once() assembly function
- Address a few minor static analysis and kernel-doc warnings"

Pull x86 apic update from Thomas Gleixner:
"A set of changes for the x86 APIC code:
- Handle the case where x2APIC is enabled and locked by the BIOS on a
kernel with CONFIG_X86_X2APIC=n gracefully.
Instead of a panic which does not make it to the graphical console
during very early boot, simply disable the local APIC completely
and boot with the PIC and very limited functionality, which allows
to diagnose the issue
- Convert x86 APIC device tree bindings to YAML
- Extend x86 APIC device tree bindings to configure interrupt
delivery mode and handle this in during init. This allows to boot
with device tree on platforms which lack a legacy PIC"

Pull CPU hotplug updates from Thomas Gleixner:
"A small set of updates for CPU hotplug:
- Prevent stale CPU hotplug state in the cpu_down() path which was
detected by stress testing the sysfs interface
- Ensure that the target CPU hotplug state for the boot CPU is
CPUHP_ONLINE instead of the compile time init value CPUHP_OFFLINE.
- Switch back to the original behaviour of warning when a CPU hotplug
callback in the DYING/STARTING section returns an error code.
Otherwise a buggy callback can leave the CPUs in an non recoverable
state"
