"Including fixes from netfilter, wifi and ipsec.
A little more changes than usual, but it's pretty normal for us that

more of an unscientific hunch.

Add new network selftests for the bonding device which exercise the ether
type changing call paths. They also test for the recent syzbot bug[1] which
causes a warning and results in wrong device flags (IFF_SLAVE missing).
The test adds three bond devices and a nlmon device, enslaves one of the
bond devices to the other and then uses the nlmon device for successful
and unsuccesful enslaves both of which change the bond ether type. Thus
we can test for both MASTER and SLAVE flags at the same time.
If the flags are properly restored we get:
TEST: Change ether type of an enslaved bond device with unsuccessful enslave [ OK ]
TEST: Change ether type of an enslaved bond device with successful enslave [ OK ]

The `devlink -j port show` command output may not contain the "flavour"
key, an example from Ubuntu 22.10 s390x LPAR(5.19.0-37-generic), with
mlx4 driver and iproute2-5.15.0:
{"port":{"pci/0001:00:00.0/1":{"type":"eth","netdev":"ens301"},
"pci/0001:00:00.0/2":{"type":"eth","netdev":"ens301d1"},

"pci/0002:00:00.0/2":{"type":"eth","netdev":"ens317d1"}}}
This will cause a KeyError exception.
Create a validate_devlink_output() to check for this "flavour" from
devlink command output to avoid this KeyError exception. Also let
it handle the check for `devlink -j dev show` output in main().
Apart from this, if the test was not started because the max lanes of
the designated device is 0. The script will still return 0 and thus
causing a false-negative test result.
Use a found_max_lanes flag to determine if these tests were skipped
due to this reason and return KSFT_SKIP to make it more clear.

When kvm_xen_evtchn_send() takes the slow path because the shinfo GPC
needs to be revalidated, it used to violate the SRCU vs. kvm->lock
locking rules and potentially cause a deadlock.
Now that lockdep is learning to catch such things, make sure that code
path is exercised by the selftest.

The xen_shinfo_test started off with very few iterations, and the numbers
we used in GUEST_SYNC() were precisely mapped to the RUNSTATE_xxx values
anyway to start with.
It has since grown quite a few more tests, and it's kind of awful to be
handling them all as bare numbers. Especially when I want to add a new
test in the middle. Define an enum for the test stages, and use it both
in the guest code and the host switch statement.
No functional change, if I can count to 24.

Right now, if KVM memory stress tests are run with hugetlb sources but hugetlb is
not available (either in the kernel or because /proc/sys/vm/nr_hugepages is 0)
the test will fail with a memory allocation error.
This makes it impossible to add tests that default to hugetlb-backed memory,
because on a machine with a default configuration they will fail. Therefore,
check HugePages_Total as well and, if zero, direct the user to enable hugepages
in procfs. Furthermore, return KSFT_SKIP whenever hugetlb is not available.

Pull clone3 fix from Christian Brauner:
"A simple fix for the clone3() system call.
The CLONE_NEWTIME allows the creation of time namespaces. The flag
reuses a bit from the CSIGNAL bits that are used in the legacy clone()
system call to set the signal that gets sent to the parent after the
child exits.
The clone3() system call doesn't rely on CSIGNAL anymore as it uses a
dedicated .exit_signal field in struct clone_args. So we blocked all
CSIGNAL bits in clone3_args_valid(). When CLONE_NEWTIME was introduced
and reused a CSIGNAL bit we forgot to adapt clone3_args_valid()
causing CLONE_NEWTIME with clone3() to be rejected. Fix this"

a total of 9 files changed, 64 insertions(+), 18 deletions(-).
The main changes are:
1) Fix BTF resolver for DATASEC sections when a VAR points at a modifier,
that is, keep resolving such instances instead of bailing out,
from Lorenz Bauer.
2) Fix BPF test framework with regards to xdp_frame info misplacement
in the "live packet" code, from Alexander Lobakin.
3) Fix an infinite loop in BPF sockmap code for TCP/UDP/AF_UNIX,
from Liu Jian.
4) Fix a build error for riscv BPF JIT under PERF_EVENTS=n,
from Randy Dunlap.

Bring back the Python scripts that were initially added with
TEST_GEN_FILES but now with TEST_FILES to avoid having them deleted
when doing a clean. Also fix the way the architecture is being
determined as they should also be installed when ARCH=x86_64 is
provided explicitly. Then also append extra files to TEST_FILES and
TEST_PROGS with += so they don't get discarded.

&xdp_buff and &xdp_frame are bound in a way that
xdp_buff->data_hard_start == xdp_frame
It's always the case and e.g. xdp_convert_buff_to_frame() relies on
this.
IOW, the following:
for (u32 i = 0; i < 0xdead; i++) {
xdpf = xdp_convert_buff_to_frame(&xdp);
xdp_convert_frame_to_buff(xdpf, &xdp);
}
shouldn't ever modify @xdpf's contents or the pointer itself.
However, "live packet" code wrongly treats &xdp_frame as part of its
context placed *before* the data_hard_start. With such flow,
data_hard_start is sizeof(*xdpf) off to the right and no longer points
to the XDP frame.
Instead of replacing `sizeof(ctx)` with `offsetof(ctx, xdpf)` in several
places and praying that there are no more miscalcs left somewhere in the
code, unionize ::frm with ::data in a flex array, so that both starts
pointing to the actual data_hard_start and the XDP frame actually starts
being a part of it, i.e. a part of the headroom, not the context.
A nice side effect is that the maximum frame size for this mode gets
increased by 40 bytes, as xdp_buff::frame_sz includes everything from
data_hard_start (-> includes xdpf already) to the end of XDP/skb shared
info.
Also update %MAX_PKT_SIZE accordingly in the selftests code. Leave it
hardcoded for 64 bit && 4k pages, it can be made more flexible later on.
Minor: align `&head->data` with how `head->frm` is assigned for
consistency.
Minor #2: rename 'frm' to 'frame' in &xdp_page_head while at it for
clarity.
(was found while testing XDP traffic generator on ice, which calls
xdp_convert_frame_to_buff() for each XDP frame)

Back in 2008 we extended the capability bits from 32 to 64, and we did
it by extending the single 32-bit capability word from one word to an
array of two words. It was then obfuscated by hiding the "2" behind two
macro expansions, with the reasoning being that maybe it gets extended
further some day.
That reasoning may have been valid at the time, but the last thing we
want to do is to extend the capability set any more. And the array of
values not only causes source code oddities (with loops to deal with
it), but also results in worse code generation. It's a lose-lose
situation.
So just change the 'u32[2]' into a 'u64' and be done with it.
We still have to deal with the fact that the user space interface is
designed around an array of these 32-bit values, but that was the case
before too, since the array layouts were different (ie user space
doesn't use an array of 32-bit values for individual capability masks,
but an array of 32-bit slices of multiple masks).
So that marshalling of data is actually simplified too, even if it does
remain somewhat obscure and odd.
This was all triggered by my reaction to the new "cap_isidentical()"
introduced recently. By just using a saner data structure, it went from
unsigned __capi;
CAP_FOR_EACH_U32(__capi) {
if (a.cap[__capi] != b.cap[__capi])
return false;
}
return true;
to just being
return a.val == b.val;
instead. Which is rather more obvious both to humans and to compilers.

The test_local_dnat_portonly() function initiates the client-side as
soon as it sets the listening side to the background. This could lead to
a race condition where the server may not be ready to listen. To ensure
that the server-side is up and running before initiating the
client-side, a delay is introduced to the test_local_dnat_portonly()
function.

- A preamble to adding support for nested virtualization to KVM,

Pull Compute Express Link (CXL) updates from Dan Williams:
"To date Linux has been dependent on platform-firmware to map CXL RAM
regions and handle events / errors from devices. With this update we
can now parse / update the CXL memory layout, and report events /
errors from devices. This is a precursor for the CXL subsystem to
handle the end-to-end "RAS" flow for CXL memory. i.e. the flow that
for DDR-attached-DRAM is handled by the EDAC driver where it maps
system physical address events to a field-replaceable-unit (FRU /
endpoint device). In general, CXL has the potential to standardize
what has historically been a pile of memory-controller-specific error
handling logic.
Another change of note is the default policy for handling RAM-backed
device-dax instances. Previously the default access mode was "device",
mmap(2) a device special file to access memory. The new default is
"kmem" where the address range is assigned to the core-mm via
add_memory_driver_managed(). This saves typical users from wondering
why their platform memory is not visible via free(1) and stuck behind
a device-file. At the same time it allows expert users to deploy
policy to, for example, get dedicated access to high performance
memory, or hide low performance memory from general purpose kernel
allocations. This affects not only CXL, but also systems with
high-bandwidth-memory that platform-firmware tags with the
EFI_MEMORY_SP (special purpose) designation.
Summary:
- CXL RAM region enumeration: instantiate 'struct cxl_region' objects
for platform firmware created memory regions
- CXL RAM region provisioning: complement the existing PMEM region
creation support with RAM region support

out trace event output.
- Add kernel command line to create trace instances on boot up.
- Add enabling of events to instances created at boot up.
- Add trace_array_puts() to write into instances.
- Allow boot instances to take a snapshot at the end of boot up.

Initial support of HID-BPF (Benjamin Tissoires)
The history is a little long for this series, as it was intended to be
sent for v6.2. However some last minute issues forced us to postpone it
to v6.3.
Conflicts:
* drivers/hid/i2c-hid/Kconfig:
commit bf7660dab3 ("HID: stop drivers from selecting CONFIG_HID")
conflicts with commit 2afac81dd1 ("HID: fix I2C_HID not selected
when I2C_HID_OF_ELAN is")
the resolution is simple enough: just drop the "default" and "select"
lines as the new commit from Arnd is doing
