Pull ACPI support fixes from Rafael Wysocki:

Pull vfs fixes from Christian Brauner:
- netfs:
- fix the decision when to disallow write-streaming with fscache in
use, handling of asynchronous cache object creation, a double fput
in cachefiles, clearing S_KERNEL_FILE without the inode lock held,
page extraction bugs in the iov_iter helpers (a potential
underflow, a missing allocation failure check, a memory leak, and
a folio offset miscalculation), writeback error and ENOMEM
handling, DIO write retry for filesystems without a
->prepare_write() method, and the replacement of the wb_lock mutex
with a bit lock plus writethrough collection offload so that
multiple asynchronous writebacks don't interfere with each other.
- Fix the barriering when walking the netfs subrequest list during
retries as it was possible to see a subrequest that was just added
by the application thread.
- iomap:
- Change iomap to submit read bios after each extent instead of
building them up across extents. The old behavior was considered
problematic for a while and now caused an actual erofs bug.
- Guard the ioend io_size EOF trim in iomap against underflow when a
concurrent truncate moves EOF below the start of the ioend,
wrapping io_size to a huge value.
- overlayfs
- Fix a stale overlayfs comment about the locking order.
- Store the linked-in upper dentry instead of the disconnected
O_TMPFILE dentry during overlayfs tmpfile copy-up. With a FUSE or
virtiofs upper layer ->d_revalidate() would try to look up "/" in
the workdir and fail, causing persistent ESTALE errors that broke
dpkg and apt.
- vfs-bpf:
Have the bpf_real_data_inode() kfunc take a struct file instead of a
dentry so it is usable from the bprm_check_security, mmap_file, and
file_mprotect hooks, and rename it from bpf_real_inode() to make the
data-inode semantics explicit. The kfunc landed this cycle so the
change is safe.
- afs:
NULL pointer dereferences in the callback service and in
afs_get_tree(), several memory and refcount leaks, missing locking
around the dynamic root inode numbers and premature cell exposure
through /afs, a netns destruction hang caused by a misplaced
increment of net->cells_outstanding, a bulk lookup malfunction caused
by the dir_emit() API change, inode (re)initialisation issues, and
assorted smaller fixes to error codes, seqlock handling, and debug
output.
- vfs:
Refuse O_TMPFILE creation with an unmapped fsuid or fsgid and add a
selftest for it.
- vboxsf:
Add Jori Koolstra as vboxsf maintainer, taking over from Hans de
Goede.
- dio:
Release the pages attached to a short atomic dio bio; the REQ_ATOMIC
size check error path leaked them.
- procfs:
Only bump the parent directory link count when registering
directories in procfs. Registering regular files inflated the count
and leaked a link on every create and remove cycle.
- minix:
Avoid an unsigned overflow in the minix bitmap block count
calculation that let crafted images with huge inode or zone counts
pass superblock validation and crash the kernel during mount.
- cachefiles:
Fix a double unlock in the cachefiles nomem_d_alloc error path left
over from the start_creating() conversion.
- fat:
Stop fat from reading directory entries past the 0x00
end-of-directory marker. If the trailing on-disk slots aren't
zero-filled the driver surfaced arbitrary garbage as directory
entries.
- freexvfs:
Don't BUG() on unknown typed-extent types in freevxfs, reachable via
ioctl(FIBMAP) on a crafted image; fail with an I/O error instead.
- orangefs:
Keep the readdir entry size 64-bit in orangefs fill_from_part().
Truncating it to __u32 bypassed the bounds check and led to
out-of-bounds reads triggerable by the userspace client.
- xfs:
Fix the error unwind in xfs_open_devices() which released the rt
device file twice and left dangling buftarg pointers behind that were
freed again when the failed mount was torn down.
- exec:
Fix an off-by-one in the comment documenting the maximum binfmt
rewrite depth in exec_binprm(). The code allows five rewrites, not
four; restricting the code would break userspace so the comment is
fixed instead.
- file handles:
Reject detached mounts in capable_wrt_mount(). A detached mount can
be dissolved concurrently, leaving a NULL mount namespace that
open_by_handle_at() would dereference.

Pull mod_devicetable.h header split from Uwe Kleine-König:
"Split <linux/mod_devicetable.h> in per subsystem headers
<linux/mod_devicetable.h> is included transitively in nearly every
driver in an x86_64 allmodconfig build of v7.1:
$ find drivers -name \*.o -not -name \*.mod.o | wc -l
21330
$ find drivers -name \*.o.cmd -not -name \*.mod.o.cmd | xargs grep -l mod_devicetable.h | wc -l
17038
The result of this mixture of different and unrelated subsystem
details is that even when touching an obscure device id struct most of
the kernel needs to be recompiled. Given that each driver typically
only needs one or two of these structures, splitting into per
subsystem headers and only including what is really needed reduces the
amount of needed recompilation.
This split is implemented in the first commit and then after some
preparatory work in the following commits, the last two replace
includes of <linux/mod_devicetable.h> by the actually needed more
specific headers.
There are still a few instances left, but the ones with high impact
(that is in headers that are used a lot) and the easy ones (.c files)
are handled. These remaining includes will be addressed during the
next merge window"

(headers)
<linux/mod_devicetable.h> is included in a many files:
$ git grep '<linux/mod_devicetable.h>' ef0c9f75a195 | wc -l
1598
; some of them are widely used headers. To stop mixing up different and
unrelated driver( type)s let the subsystem headers only use the subset
of the recently split <linux/mod_devicetable.h> that are relevant for
them.
The fallout (I hope) is addressed in the previous commits that handle
sources relying on e.g. <linux/i2c.h> pulling in the full legacy header
and thus providing pci_device_id.

Traditionally all *_device_id were defined in a single header
<linux/mod_devicetable.h>. This was split now with the objective that
only the relevant bits are included. So including <linux/pci.h> won't be
enough to get a definition of (the unrelated to pci) struct
hda_device_id.
Add an explicit include for the header defining struct hda_device_id to
keep working when <linux/pci.h> stops providing this defintion.

<linux/of_platform.h> uses resource_size_t and relies on the transitive
include <linux/mod_devicetable.h> -> <linux/types.h>. It also uses error
constants and thus relying on the include chain
<linux/mod_devicetable.h> -> <linux/uuid.h> -> <linux/string.h> ->
<linux/err.h>.
With the plan to split <linux/mod_devicetable.h> per subsystem and then
only letting of_platform.h include the of-specific bits (which don't
require these two headers), add the needed includes explicitly to keep
the header self-contained.

Platform drivers can define an array containing the supported device
variants to be assigned to the struct platform_driver's .id_table.
While a forward declaration of struct platform_device_id is technically
enough to make the driver self-contained, it's reasonable to provide the
(very lightweight) data type definition for that array in
<linux/platform_device.h> to not add that burden to all platform drivers
with an id-table.
Note that currently <linux/device.h> transitively includes
<linux/mod_devicetable.h> that provides struct platform_device_id. But
that include is planned to be replaced by a tighter set of includes that
only define the structures relevant for the stuff in <linux/device.h>.

<linux/mod_devicetable.h> is included transitively in nearly every

$ find drivers -name \*.o -not -name \*.mod.o | wc -l
21330
$ find drivers -name \*.o.cmd -not -name \*.mod.o.cmd | xargs grep -l mod_devicetable.h | wc -l

only needs one or two of these structures, splitting into per subsystem

Implement the first step and define each device id struct in a separate
header (together with its associated #defines).
<linux/mod_devicetable.h> is modified to include all the new headers to
continue to provide the same symbols.
Several headers currently include <linux/mod_devicetable.h>, those that
are most lukrative to include only their subsystem headers only are:
$ git -C source grep -l mod_devicetable.h include/linux | while read h; do echo -n "$h:"; find drivers -name \*.o.cmd -not -name \*.mod.o.cmd | xargs grep -l $h | wc -l; done | sort -t: -k2 -n -r | head

- Fix runtime PM inconsistency where the vfio-pci driver module_init
could modify the idle PM policy of existing devices through globals
managed in vfio-pci-core, leading to unbalanced runtime PM
operations (Alex Williamson)
- Restore mutability of writable vfio-pci module options by further

per device at device init. Provide visibility of the per device
latched values through debugfs (Alex Williamson)
- Fix missing VGA arbiter uninit callback in unwind path (Alex

Add a iomap_bio_submit_read_endio helper factored out of
iomap_bio_submit_read to that all ->submit_read implementations for
iomap_read_ops that use iomap_bio_read_folio_range can shared the
logic.
Right now that logic is mostly trivial, but already has a bug for XFS
because the XFS version is too trivial: file system integrity validation
needs a workqueue context and thus can't happen from the default iomap
bi_end_io I/O handler. Unfortunately the iomap refactoring just before
fs integrity landed moved code around here and the call go misplaced,
meaning it never got called. The PI information still is verified by
the block layer, but the offloading is less efficient (and the future
userspace interface can't get at it).

The netfs_inode::wb_lock mutex is used to prevent multiple simultaneous
writebacks from fighting each other (a writeback thread will write multiple
discontiguous regions within the same request). The mutex, however, only
serialises the issuing of subrequests; it doesn't serialise the collection
of results, and, in particular, the updating of file size information and
fscache populatedness data.
Unfortunately, the mutex cannot be held around the entire process as it has
to be unlocked in the same thread in which it is locked - and we don't want
to hold up the allocator whilst we complete the writeback.
Fix this by replacing the mutex with a bit flag and a list of lock waiters
so that the lock can be dropped in the collector thread after collection is
complete.

Commit 292db66afd20 ("ACPICA: Unbreak tools build after switching over
to strscpy_pad()") added an #ifdef based on a __KERNEL__ check which is
sort of nasty to the acpi_ut_safe_strncpy() definition to unbreak ACPICA
tools builds broken by commit 97f7d3f9c9ac ("ACPICA: Replace strncpy()
with strscpy_pad() in acpi_ut_safe_strncpy()"). However, that #ifdef
effectively produces dead code when tools are built because they don't
call acpi_ut_safe_strncpy().
Accordingly, drop the existing definition of acpi_ut_safe_strncpy() and
define it as a strscpy_pad() alias.

Currently predictor flush on memory reuse is done for all BPF JIT
allocations, but only cBPF programs can be loaded by an unprivileged user.
eBPF is privileged by default, and flushing predictors for all CPUs on
every eBPF reuse penalizes the common case for no security benefit.
eBPF allocations can be frequent on busy systems, only flush predictors
for cBPF programs. Trampoline and dispatcher allocations also skip the
flush as they are eBPF-only.

The BPF JIT allocator packs many small programs into larger executable
allocations and reuses space within those allocations as programs are
loaded and freed. When fresh code is written into space that a previous
program occupied, an indirect jump into the new program can reuse a branch
prediction left behind by the old one.
Flush the indirect branch predictors before reusing JIT memory so that
indirect jumps into a newly written program don't reuse predictions from an
old program that occupied the same space.
Introduce bpf_arch_pred_flush_enabled static key and bpf_arch_pred_flush
static call for flushing the branch predictors on JIT memory reuse.
Architectures that need a flush, can update it to a predictor flush
function. By default, its a NOP and does not emit any CALL.
Allocations larger than a pack are not covered by this flush. That is safe
because cBPF programs (the unprivileged attack surface) are bounded well
below a pack size. Issue a warning if this assumption is ever violated
while the flush is active.

While the GCC and Clang compilers already define __ASSEMBLER__
automatically when compiling assembly code, __ASSEMBLY__ is a
macro that only gets defined by the Makefiles in the kernel.
This can be very confusing when switching between userspace
and kernelspace coding, or when dealing with uapi headers that
rather should use __ASSEMBLER__ instead. So let's standardize now
on the __ASSEMBLER__ macro that is provided by the compilers.
This is a completely mechanical patch (done with a simple "sed -i"
statement).

When CONFIG_BPF_LSM=y is set, BPF inode storage maps
(BPF_MAP_TYPE_INODE_STORAGE) are compiled into the kernel. However,
if the BPF LSM is not explicitly enabled at boot time (e.g. omitted
from the "lsm=" boot parameter), lsm_prepare() is never executed for
the BPF LSM.
Consequently, the BPF inode security blob offset
(bpf_lsm_blob_sizes.lbs_inode) is never initialized and remains at
its default compiled size of 8 bytes instead of being updated to a
valid offset past the reserved struct rcu_head (typically 16 bytes
or more).
When a privileged user creates and updates a BPF_MAP_TYPE_INODE_STORAGE
map, bpf_inode() evaluates inode->i_security + 8. This erroneously
aliases the struct rcu_head.func callback pointer at the beginning
of the inode->i_security blob. During subsequent map element cleanup
or inode destruction, writing NULL to owner_storage clears the queued
RCU callback pointer. When rcu_do_batch() later executes the queued
callback, it attempts an instruction fetch at address 0x0, triggering
an immediate kernel panic.
Fix this by introducing a global bpf_lsm_initialized boolean flag
marked with __ro_after_init. Set this flag to true inside bpf_lsm_init()
when the LSM framework successfully registers the BPF LSM. Gate map
allocation in inode_storage_map_alloc() on this flag, returning
-EOPNOTSUPP if the BPF LSM is in turn uninitialized.
This fail-fast approach prevents userspace from allocating inode
storage maps when the supporting BPF LSM infrastructure is absent,
avoiding zombie map states.

Commit 51e547e8c89c ("tcp: Free TCP-AO/TCP-MD5 info/keys without RCU")
removed the call_rcu() callback from tcp_ao_destroy_sock(), arguing that
"the destruction of info/keys is delayed until the socket destructor"
and therefore "no one can discover it anymore".
That argument does not hold for the call site in tcp_connect()
(net/ipv4/tcp_output.c:4327-4332). At that point the socket is in
TCP_SYN_SENT, has already been inserted into the inet ehash by
inet_hash_connect() in tcp_v4_connect(), and is therefore very much
discoverable: any softirq running tcp_v4_rcv() on another CPU can take
the socket out of the ehash, walk into tcp_inbound_hash(), and load
tp->ao_info via implicit RCU before bh_lock_sock_nested() is taken on
the destroying CPU.
The reader path then enters __tcp_ao_do_lookup() (net/ipv4/tcp_ao.c:208)
which re-loads tp->ao_info via rcu_dereference_check(); the re-load can
still observe the (about-to-be-freed) pointer because there is no
synchronize_rcu() between rcu_assign_pointer(tp->ao_info, NULL) and
tcp_ao_info_free() in tcp_ao_destroy_sock(). The captured pointer is
then walked at line 223:
hlist_for_each_entry_rcu(key, &ao->head, node, ...)
The writer's synchronous kfree() is free to complete between the line
218 re-fetch and the line 223 hlist iteration. The slab is reused
(or simply LIST_POISON1-stamped if not yet reused) and the iteration
walks attacker-controlled or poison memory in softirq context.
Reproducer (no debug shim, stock x86_64 v7.1-rc2 SMP+KASAN, QEMU+KVM):
an unprivileged uid=1000 process inside CLONE_NEWUSER|CLONE_NEWNET
installs TCP_MD5SIG + TCP_AO_ADD_KEY on a TCP socket, sprays forged
TCP-AO segments toward its eventual 4-tuple via raw sockets, then
calls connect(). The md5-wins reconciliation in tcp_connect() fires
tcp_ao_destroy_sock(); the softirq backlog reader on the loopback
NAPI path crashes on the freed ao->head.first walk:
Oops: general protection fault, probably for non-canonical
address 0xfbd59c000000002f
KASAN: maybe wild-memory-access in range
[0xdead000000000178-0xdead00000000017f]
CPU: 0 UID: 1000 PID: 100 Comm: repro_userns

Restore the RCU grace period: re-add struct rcu_head to tcp_ao_info
and replace the synchronous tcp_ao_info_free() with a call_rcu()
callback. Readers that captured tp->ao_info before rcu_assign_pointer
NULLed it now see the object remain valid until rcu_read_unlock().
With the patch applied the reproducer runs cleanly for 2000 iterations
on the same kernel build.

The vfio-pci module parameters of disable_idle_d3, nointxmask, and
disable_vga latch vfio-pci policy into vfio-pci-core globals each time
the vfio-pci module is initialized. The disable_idle_d3 parameter has
already migrated to a per-device flag in order to provide consistency
for refcounted PM operations for the lifetime of the device
registration.
Pull the remaining vfio-pci module-parameter policy out of vfio-pci-core
into per-device flags set at device initialization.
This also restores the mutable aspect of the disable_idle_d3 and
nointxmask module parameters for vfio-pci, with the caveat that the
parameters are latched into the device at probe.
A notable change for variant drivers is that their devices are no longer
affected by vfio-pci module parameters and those drivers may need to
adopt similar module parameters if any devices have a hidden dependency
on vfio-pci setting non-default policy.

Bitfield operations are not atomic, they use a read-modify-write
pattern, therefore we should be careful not to pack bitfields that
can be concurrently updated into the same storage unit.
This split takes a binary approach: flags that are only modified
pre/post open/close remain bitfields, flags modified from user
action, including actions that reach across to another device (ex.
reset) use dedicated storage units.
Note that the virq_disabled and bardirty flags are relocated to fill
an existing hole in the structure.
Bitfield justifications:
has_dyn_msix: written only in vfio_pci_core_enable()
pci_2_3: written only in vfio_pci_core_enable()
reset_works: written only in vfio_pci_core_enable()
extended_caps: written only in vfio_cap_len() under vfio_config_init()
has_vga: written only in vfio_pci_core_enable()
nointx: written only in vfio_pci_core_enable()
needs_pm_restore: written only in vfio_pci_probe_power_state()
disable_idle_d3: written only at .init in vfio_pci_core_init_dev()
Dedicated storage units:
virq_disabled: written by guest INTx command writes in
vfio_basic_config_write() while the device is open
bardirty: written by guest BAR writes in vfio_basic_config_write()
while the device is open
pm_intx_masked: written in the runtime-PM suspend path.
pm_runtime_engaged: written by low-power feature entry/exit paths
needs_reset: set in vfio_pci_core_disable() and cleared for devices in
the set by vfio_pci_dev_set_try_reset()
sriov_active: written by vfio_pci_core_sriov_configure() via sysfs
sriov_numvfs while bound.

When disable_idle_d3 was introduced in vfio-pci, it directly manipulated
the device power state with pci_set_power_state(). There were no
refcounts to maintain or balanced operations, we could unconditionally
bring the device to D0 and conditionally move it to D3hot. Therefore
the module parameter was made writable.
Later, in commit c61302aa48f7 ("vfio/pci: Move module parameters to
vfio_pci.c"), as part of the vfio-pci-core split, the writable aspect
of the module parameter was nullified. The parameter value could still
be changed through sysfs, but the vfio-pci driver latched the values
into vfio-pci-core globals at module init. Loading the vfio-pci module,
or unloading and reloading, with non-default or different values could
change the globals relative to existing devices bound to vfio-pci
variant drivers.
Runtime PM was introduced in commit 7ab5e10eda02 ("vfio/pci: Move the
unused device into low power state with runtime PM"), which marks the
point where power states became refcounted. PM get and put operations
need to be balanced, but the same module operations noted above can
change the global variables relative to those devices already bound to
vfio-pci variant drivers. This introduces a window where PM operations
can now become unbalanced.
To resolve this with a narrow footprint for stable backports, the
disable_idle_d3 flag is latched into the vfio_pci_core_device at the
time of initialization, such that the device always operates with a
consistent value.
NB. vfio_pci_dev_set_try_reset() now unconditionally raises the
runtime PM usage count around bus reset to account for disable_idle_d3
becoming a per-device rather than global flag. When this flag is set,
the additional get/put pair is harmless and allows continued use of the
shared vfio_pci_dev_set_pm_runtime_get() helper.

ASoC: Fixes for v7.2
We've got a good collection of device specific fix here, plus a couple
of stand out things:
- Richard fixed some special cases with the new device_link creation
by more gracefully handling any errors during creation.
- Charles did some light refactoring of the SoundWire interfaces to
fix some persistent randconfig issues that people kept running into.

With an extra event mask we can easily extend the netdev work
to also service driver-defined events. For advanced drivers
this is probably not a perfect match, but it makes running
deferred work easier in simple cases.
Expose the netdev_work facility to drivers. Add helpers
to schedule work and a dedicated ndo to perform the driver-
-scheduled actions.

The rx_mode update runs from a workqueue: drivers have their
ndo_set_rx_mode_async() callback executed by a single global
work item under RTNL and ops lock. This is a useful pattern.
Support multiple "events" that need to be serviced and make RX_MODE
sync the first one. Call the events "core" because later on
we will let drivers define and schedule their own.

WARNING: net/core/dev.c:2241 at netif_state_change+0xed/0x130, CPU#5: ethtool/1335

Looks like I missed ethtool_op_get_link() trying to sync linkwatch,
which needs rtnl_lock. Not all drivers do this - bnxt doesn't,
it just returns the link state, so add an opt-in bit.
