Pull kvm fixes from Paolo Bonzini:
"x86:
- Fixes for Xen emulation. While nobody should be enabling it in the
kernel (the only public users of the feature are the selftests),
the bug effectively allows userspace to read arbitrary memory.
- Correctness fixes for nested hypervisors that do not intercept INIT
or SHUTDOWN on AMD; the subsequent CPU reset can cause a
use-after-free when it disables virtualization extensions. While
downgrading the panic to a WARN is quite easy, the full fix is a
bit more laborious; there are also tests. This is the bulk of the
pull request.
- Fix race condition due to incorrect mmu_lock use around
make_mmu_pages_available().
Generic:
- Obey changes to the kvm.halt_poll_ns module parameter in VMs not
using KVM_CAP_HALT_POLL, restoring behavior from before the
introduction of the capability"

Commit 868f9f2f8e00 ("vfs: fix copy_file_range() regression in cross-fs
copies") removed fallback to generic_copy_file_range() for cross-fs
cases inside vfs_copy_file_range().
To preserve behavior of nfsd and ksmbd server-side-copy, the fallback to
generic_copy_file_range() was added in nfsd and ksmbd code, but that
call is missing sb_start_write(), fsnotify hooks and more.
Ideally, nfsd and ksmbd would pass a flag to vfs_copy_file_range() that
will take care of the fallback, but that code would be subtle and we got
vfs_copy_file_range() logic wrong too many times already.
Instead, add a flag to explicitly request vfs_copy_file_range() to
perform only generic_copy_file_range() and let nfsd and ksmbd use this
flag only in the fallback path.
This choise keeps the logic changes to minimum in the non-nfsd/ksmbd code
paths to reduce the risk of further regressions.

The type of a->key[0] is char in fscache_volume_same(). If the length
of cache volume key is greater than 127, the value of a->key[0] is less
than 0. In this case, klen becomes much larger than 255 after type
conversion, because the type of klen is size_t. As a result, memcmp()
is read out of bounds.
This causes a slab-out-of-bounds Read in __fscache_acquire_volume(), as
reported by Syzbot.
Fix this by changing the type of the stored key to "u8 *" rather than
"char *" (it isn't a simple string anyway). Also put in a check that
the volume name doesn't exceed NAME_MAX.

ASoC: Fixes for v6.1
A clutch of small fixes that have come in in the past week, people seem
to have been unusually active for this late in the release cycle. The
most critical one here is the fix to renumber the SOF DAI types in order
to restore ABI compatibility which was broken by the addition of AMD
support.

If a socket bound to a wildcard address fails to connect(), we
only reset saddr and keep the port. Then, we have to fix up the
bhash2 bucket; otherwise, the bucket has an inconsistent address
in the list.
Also, listen() for such a socket will fire the WARN_ON() in
inet_csk_get_port(). [0]
Note that when a system runs out of memory, we give up fixing the
bucket and unlink sk from bhash and bhash2 by inet_put_port().

When we specify __GFP_NOWARN, we only expect that no warnings will be
issued for current caller. But in the __should_failslab() and
__should_fail_alloc_page(), the local GFP flags alter the global
{failslab|fail_page_alloc}.attr, which is persistent and shared by all
tasks. This is not what we expected, let's fix it.

While moving to new CMD API (quiet API), some pre-existing flows may call the new API
function that in case of error, returns the error instead of printing it as previously done.
For such flows we bring back the print but to tracepoint this time for sys admins to
have the ability to check for errors especially for commands using the new quiet API.
Tracepoint output example:

Commit 0ff4eb3d5ebb ("neighbour: make proxy_queue.qlen limit
per-device") introduced the length counter qlen in struct neigh_parms.
There are separate neigh_parms instances for IPv4/ARP and IPv6/ND, and
while the family specific qlen is incremented in pneigh_enqueue(), the
mentioned commit decrements always the IPv4/ARP specific qlen,
regardless of the currently processed family, in pneigh_queue_purge()
and neigh_proxy_process().
As a result, with IPv6/ND, the family specific qlen is only incremented
(and never decremented) until it exceeds PROXY_QLEN, and then, according
to the check in pneigh_enqueue(), neighbor solicitations are not
answered anymore. As an example, this is noted when using the
subnet-router anycast address to access a Linux router. After a certain
amount of time (in the observed case, qlen exceeded PROXY_QLEN after two
days), the Linux router stops answering neighbor solicitations for its
subnet-router anycast address and effectively becomes unreachable.
Another result with IPv6/ND is that the IPv4/ARP specific qlen is
decremented more often than incremented. This leads to negative qlen
values, as a signed integer has been used for the length counter qlen,
and potentially to an integer overflow.
Fix this by introducing the helper function neigh_parms_qlen_dec(),
which decrements the family specific qlen. Thereby, make use of the
existing helper function neigh_get_dev_parms_rcu(), whose definition
therefore needs to be placed earlier in neighbour.c. Take the family
member from struct neigh_table to determine the currently processed
family and appropriately call neigh_parms_qlen_dec() from
pneigh_queue_purge() and neigh_proxy_process().
Additionally, use an unsigned integer for the length counter qlen.

Having REQ_F_POLLED set doesn't guarantee that the request is
executed as a multishot from the polling path. Fortunately for us, if
the code thinks it's multishot issue when it's not, it can only ask to
skip completion so leaking the request. Use issue_flags to mark
multipoll issues.

Obey kvm.halt_poll_ns in VMs not using KVM_CAP_HALT_POLL on every halt,
rather than just sampling the module parameter when the VM is first
created. This restore the original behavior of kvm.halt_poll_ns for VMs
that have not opted into KVM_CAP_HALT_POLL.
Notably, this change restores the ability for admins to disable or
change the maximum halt-polling time system wide for VMs not using
KVM_CAP_HALT_POLL.

Currently the way polling works on the ring buffer is broken. It will
return immediately if there's any data in the ring buffer whereas a read
will block until the watermark (defined by the tracefs buffer_percent file)
is hit.
That is, a select() or poll() will return as if there's data available,
but then the following read will block. This is broken for the way
select()s and poll()s are supposed to work.
Have the polling on the ring buffer also block the same way reads and
splice does on the ring buffer.

sk->sk_user_data has multiple users, which are not compatible with each
other. Writers must synchronize by grabbing the sk->sk_callback_lock.
l2tp currently fails to grab the lock when modifying the underlying tunnel
socket fields. Fix it by adding appropriate locking.
We err on the side of safety and grab the sk_callback_lock also inside the
sk_destruct callback overridden by l2tp, even though there should be no
refs allowing access to the sock at the time when sk_destruct gets called.
v4:
- serialize write to sk_user_data in l2tp sk_destruct
v3:
- switch from sock lock to sk_callback_lock
- document write-protection for sk_user_data
v2:
- update Fixes to point to origin of the bug
- use real names in Reported/Tested-by tags

they're all fairly minor though - the widest possible impact is the fix
to the use of prefixes on regulator names which would have broken any

Ampere Altra machines are reported to misbehave when the SetTime() EFI
runtime service is called after ExitBootServices() but before calling
SetVirtualAddressMap(). Given that the latter is horrid, pointless and
explicitly documented as optional by the EFI spec, we no longer invoke
it at boot if the configured size of the VA space guarantees that the
EFI runtime memory regions can remain mapped 1:1 like they are at boot
time.
On Ampere Altra machines, this results in SetTime() calls issued by the
rtc-efi driver triggering synchronous exceptions during boot. We can
now recover from those without bringing down the system entirely, due to
commit 23715a26c8d81291 ("arm64: efi: Recover from synchronous
exceptions occurring in firmware"). However, it would be better to avoid
the issue entirely, given that the firmware appears to remain in a funny
state after this.
So attempt to identify these machines based on the 'family' field in the
type #1 SMBIOS record, and call SetVirtualAddressMap() unconditionally
in that case.

The open count of a device set is the sum of the open counts of all
devices in the set. Drivers can use this value to determine whether
shared resources are in use without tracking them manually or accessing
the private open_count in vfio_device.

"Most are small fixups as described below.
The !CONFIG_TRACING fix is a bit bigger and would normally be done in

Summary:

wasted space tracking and planned hardening changes.

Along the development cycle, the testing code support for module/in-kernel
compiles was removed. Restore this functionality by moving any internal
API tests to the userspace side, as well as threading tests. Fix the
lockdep issues and add a way to reduce memory usage so the tests can
complete with KASAN + memleak detection. Make the tests work on 32 bit
hosts where possible and detect 32 bit hosts in the radix test suite.

"A small audit patch to fix an instance of undefined behavior in a
shift operator caused when shifting a signed value too far, the same
case as the lsm patch merged previously.
While the fix is trivial and I can't imagine it causing a problem in a
backport, I'm not explicitly marking it for stable on the off chance
that there is some system out there which is relying on some wonky
unexpected behavior which this patch could break; *if* it does break,
IMO it's better that to happen in a minor or -rcX release and not in a
stable backport"
