ksmbd: fix slab-out-of-bounds in smb_strndup_from_utf16()
If ->NameOffset of smb2_create_req is smaller than Buffer offset of smb2_create_req, slab-out-of-bounds read can happen from smb2_open. This patch set the minimum value of the name offset to the buffer offset to validate name length of smb2_create_req().

ovl: relax WARN_ON in ovl_verify_area()
syzbot hit an assertion in copy up data loop which looks like it is
the result of a lower file whose size is being changed underneath
overlayfs.
This type of use case is documented to cause undefined behavior, so
returning EIO error for the copy up makes sense, but it should not be
causing a WARN_ON assertion.

ring-buffer: use READ_ONCE() to read cpu_buffer->commit_page in concurrent environment
In function ring_buffer_iter_empty(), cpu_buffer->commit_page is read while other threads may change it. It may cause the time_stamp that read in the next line come from a different page. Use READ_ONCE() to avoid having to reason about compiler optimizations now and in future.

tracing: Move saved_cmdline code into trace_sched_switch.c
The code that handles saved_cmdlines is split between the trace.c file and the trace_sched_switch.c. There's some history to this. The trace_sched_switch.c was originally created to handle the sched_switch tracer that was deprecated due to sched_switch trace event making it obsolete. But that file did not get deleted as it had some code to help with saved_cmdlines. But trace.c has grown tremendously since then. Just move all the saved_cmdlines code into trace_sched_switch.c as that's the only reason that file still exists, and trace.c has gotten too big. No functional changes.

tracing: Move open coded processing of tgid_map into helper function
In preparation of moving the saved_cmdlines logic out of trace.c and into trace_sched_switch.c, replace the open coded manipulation of tgid_map in set_tracer_flag() into a helper function trace_alloc_tgid_map() so that it can be easily moved into trace_sched_switch.c without changing existing functions in trace.c.

tracing: Have saved_cmdlines arrays all in one allocation
The saved_cmdlines have three arrays for mapping PIDs to COMMs:
- map_pid_to_cmdline[]
- map_cmdline_to_pid[]
- saved_cmdlines
The map_pid_to_cmdline[] is PID_MAX_DEFAULT in size and holds the index
into the other arrays. The map_cmdline_to_pid[] is a mapping back to the
full pid as it can be larger than PID_MAX_DEFAULT. And the
saved_cmdlines[] just holds the COMMs associated to the pids.
Currently the map_pid_to_cmdline[] and saved_cmdlines[] are allocated
together (in reality the saved_cmdlines is just in the memory of the
rounding of the allocation of the structure as it is always allocated in
powers of two). The map_cmdline_to_pid[] array is allocated separately.
Since the rounding to a power of two is rather large (it allows for 8000
elements in saved_cmdlines), also include the map_cmdline_to_pid[] array.
(This drops it to 6000 by default, which is still plenty for most use
cases). This saves even more memory as the map_cmdline_to_pid[] array
doesn't need to be allocated.

eventfs: Add WARN_ON_ONCE() to checks in eventfs_root_lookup()
There's a couple of if statements in eventfs_root_lookup() that should never be true. Instead of removing them, add WARN_ON_ONCE() around them. One is a tracefs_inode not being for eventfs. The other is a child being freed but still on the parent's children list. When a child is freed, it is removed from the list under the same mutex that is held during the iteration.

powerpc/kdump: Split KEXEC_CORE and CRASH_DUMP dependency
Remove CONFIG_CRASH_DUMP dependency on CONFIG_KEXEC. CONFIG_KEXEC_CORE was used at places where CONFIG_CRASH_DUMP or CONFIG_CRASH_RESERVE was appropriate. Replace with appropriate #ifdefs to support CONFIG_KEXEC and !CONFIG_CRASH_DUMP configuration option. Also, make CONFIG_FA_DUMP dependent on CONFIG_CRASH_DUMP to avoid unmet dependencies for FA_DUMP with !CONFIG_KEXEC_CORE configuration option.

kexec/kdump: make struct crash_mem available without CONFIG_CRASH_DUMP
struct crash_mem defined under include/linux/crash_core.h represents a list of memory ranges. While it is used to represent memory ranges for kdump kernel, it can also be used for other kind of memory ranges. In fact, KEXEC_FILE_LOAD syscall in powerpc uses this structure to represent reserved memory ranges and exclude memory ranges needed to find the right memory regions to load kexec kernel.

timer/migration: Remove buggy early return on deactivation
When a CPU enters into idle and deactivates itself from the timer
migration hierarchy without any global timer of its own to propagate,
the group event of that CPU is set to "ignore" and tmigr_update_events()
accordingly performs an early return without considering timers queued
by other CPUs.
If the hierarchy has a single level, and the CPU is the last one to
enter idle, it will ignore others' global timers, as in the following
layout:
[GRP0:0]
migrator = 0
active = 0
nextevt = T0i
/ \
0 1
active (T0i) idle (T1)
0) CPU 0 is active thus its event is ignored (the letter 'i') and so are
upper levels' events. CPU 1 is idle and has the timer T1 enqueued.
[GRP0:0]
migrator = NONE
active = NONE
nextevt = T0i
/ \
0 1
idle (T0i) idle (T1)
1) CPU 0 goes idle without global event queued. Therefore KTIME_MAX is
pushed as its next expiry and its own event kept as "ignore". As a result
tmigr_update_events() ignores T1 and CPU 0 goes to idle with T1
unhandled.
This isn't proper to single level hierarchy though. A similar issue,
although slightly different, may arise on multi-level:
[GRP1:0]
migrator = GRP0:0
active = GRP0:0
nextevt = T0:0i, T0:1
/ \
[GRP0:0] [GRP0:1]
migrator = 0 migrator = NONE
active = 0 active = NONE
nextevt = T0i nextevt = T2
/ \ / \
0 (T0i) 1 (T1) 2 (T2) 3
active idle idle idle
0) CPU 0 is active thus its event is ignored (the letter 'i') and so are
upper levels' events. CPU 1 is idle and has the timer T1 enqueued.
CPU 2 also has a timer. The expiry order is T0 (ignored) < T1 < T2
[GRP1:0]
migrator = GRP0:0
active = GRP0:0
nextevt = T0:0i, T0:1
/ \
[GRP0:0] [GRP0:1]
migrator = NONE migrator = NONE
active = NONE active = NONE
nextevt = T0i nextevt = T2
/ \ / \
0 (T0i) 1 (T1) 2 (T2) 3
idle idle idle idle
1) CPU 0 goes idle without global event queued. Therefore KTIME_MAX is
pushed as its next expiry and its own event kept as "ignore". As a result
tmigr_update_events() ignores T1. The change only propagated up to 1st
level so far.
[GRP1:0]
migrator = NONE
active = NONE
nextevt = T0:1
/ \
[GRP0:0] [GRP0:1]
migrator = NONE migrator = NONE
active = NONE active = NONE
nextevt = T0i nextevt = T2
/ \ / \
0 (T0i) 1 (T1) 2 (T2) 3
idle idle idle idle
2) The change now propagates up to the top. tmigr_update_events() finds
that the child event is ignored and thus removes it. The top level next
event is now T2 which is returned to CPU 0 as its next effective expiry
to take account for as the global idle migrator. However T1 has been
ignored along the way, leaving it unhandled.
Fix those issues with removing the buggy related early return. Ignored
child events must not prevent from evaluating the other events within
the same group.

io_uring: clear opcode specific data for an early failure
If failure happens before the opcode prep handler is called, ensure that we clear the opcode specific area of the request, which holds data specific to that request type. This prevents errors where opcode handlers either don't get to clear per-request private data since prep isn't even called.

Merge tag 'cxl-for-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl
Pull CXL updates from Dan Williams:
"CXL has mechanisms to enumerate the performance characteristics of
memory devices. Those mechanisms allow Linux to build the equivalent
of ACPI SRAT, SLIT, and HMAT tables dynamically at runtime. That
capability is necessary because static ACPI can not represent dynamic
CXL configurations (and reconfigurations).
So, building on the v6.8 work to add "Quality of Service" enumeration,
this update plumbs CXL "access coordinates" (read/write access latency
and bandwidth) in all the same places that ACPI HMAT feeds similar
data. Follow-on patches from the -mm side can then use that data to
feed mechanisms like mm/memory-tiers.c. Greg has acked the touch to
drivers/base/.
The other feature update this cycle is support for CXL error injection
via the ACPI EINJ module. That facility enables injection of bus
protocol errors provided the user knows the magic address values to
insert in the interface. To hide that magic, and make this easier to
use, new error injection attributes were added to CXL debugfs. That
interface injects the errors relative to a CXL object rather than
require user tooling to know how to lookup and inject RCRB (Root
Complex Register Block) addresses into the raw EINJ debugfs interface.
It received some helpful review comments from Tony, but no explicit
acks from the ACPI side. The primary user visible change for existing
EINJ users is that they may find that einj.ko was already loaded by
cxl_core.ko. Previously, einj.ko was only loaded on demand.
The usual collection of miscellaneous cleanups are also present this
cycle.
Summary:
- Supplement ACPI HMAT reported memory performance with native CXL
memory performance enumeration
- Add support for CXL error injection via the ACPI EINJ mechanism
- Cleanup CXL DOE and CDAT integration
- Miscellaneous cleanups and fixes"

(struct nfs4_ff_layout_ds *)0xffffffffffffffed
This is clear from the stack trace, we call nfs4_ff_layout_prepare_ds()
which could error out initializing the mirror_ds, and then we go to
clean it all up and our check is only for if (!mirror->mirror_ds). This
is inconsistent with the rest of the users of mirror_ds, which have
if (IS_ERR_OR_NULL(mirror_ds))
to keep from tripping over this exact scenario. Fix this up in
ff_layout_cancel_io() to make sure we don't panic when we get an error.
I also spot checked all the other instances of checking mirror_ds and we
appear to be doing the correct checks everywhere, only unconditionally
dereferencing mirror_ds when we know it would be valid.

io_uring/net: ensure async prep handlers always initialize ->done_io
If we get a request with IOSQE_ASYNC set, then we first run the prep
async handlers. But if we then fail setting it up and want to post
a CQE with -EINVAL, we use ->done_io. This was previously guarded with
REQ_F_PARTIAL_IO, and the normal setup handlers do set it up before any
potential errors, but we need to cover the async setup too.

io_uring/waitid: always remove waitid entry for cancel all
We know the request is either being removed, or already in the process of
being removed through task_work, so we can delete it from our waitid list
upfront. This is important for remove all conditions, as we otherwise
will find it multiple times and prevent cancelation progress.
Remove the dead check in cancelation as well for the hash_node being
empty or not. We already have a waitid reference check for ownership,
so we don't need to check the list too.

VFIO updates for v6.9-rc1
- Add warning in unlikely case that device is not captured with
driver_override. (Kunwu Chan)
- Error handling improvements in mlx5-vfio-pci to detect firmware
tracking object error states, logging of firmware error syndrom,
and releasing of firmware resources in aborted migration sequence.
(Yishai Hadas)
- Correct an un-alphabetized VFIO MAINTAINERS entry.
(Alex Williamson)
- Make the mdev_bus_type const and also make the class struct const
for a couple of the vfio-mdev sample drivers. (Ricardo B. Marliere)
- Addition of a new vfio-pci variant driver for the GPU of NVIDIA's
Grace-Hopper superchip. During initialization of the chip-to-chip
interconnect in this hardware module, the PCI BARs of the device
become unused in favor of a faster, coherent mechanism for exposing
device memory. This driver primarily changes the VFIO
representation of the device to masquerade this coherent aperture
to replace the physical PCI BARs for userspace drivers. This also
incorporates use of a new vma flag allowing KVM to use write
combining attributes for uncached device memory. (Ankit Agrawal)
- Reset fixes and cleanups for the pds-vfio-pci driver. Save and
restore files were previously leaked if the device didn't pass
through an error state, this is resolved and later re-fixed to
prevent access to the now freed files. Reset handling is also
refactored to remove the complicated deferred reset mechanism.
(Brett Creeley)
- Remove some references to pl330 in the vfio-platform amba
driver. (Geert Uytterhoeven)
- Remove twice redundant and ugly code to unpin incidental pins
of the zero-page. (Alex Williamson)
- Deferred reset logic is also removed from the hisi-acc-vfio-pci
driver as a simplification. (Shameer Kolothum)
- Enforce that mlx5-vfio-pci devices must support PRE_COPY and
remove resulting unnecessary code. There is no device firmware
that has been available publicly without this support.
(Yishai Hadas)
- Switch over to using the .remove_new callback for vfio-platform
in support of the broader transition for a void remove function.
(Uwe Kleine-König)
- Resolve multiple issues in interrupt code for VFIO bus drivers
that allow calling eventfd_signal() on a NULL context. This
also remove a potential race in INTx setup on certain hardware
for vfio-pci, races with various mechanisms to mask INTx, and
leaked virqfds in vfio-platform. (Alex Williamson)

S390:
* Changes to FPU handling came in via the main s390 pull request
* Only deliver to the guest the SCLP events that userspace has
requested.
* More virtual vs physical address fixes (only a cleanup since
virtual and physical address spaces are currently the same).
* Fix selftests undefined behavior.
x86:
* Fix a restriction that the guest can't program a PMU event whose
encoding matches an architectural event that isn't included in the
guest CPUID. The enumeration of an architectural event only says
that if a CPU supports an architectural event, then the event can be
programmed *using the architectural encoding*. The enumeration does
NOT say anything about the encoding when the CPU doesn't report support
the event *in general*. It might support it, and it might support it
using the same encoding that made it into the architectural PMU spec.
* Fix a variety of bugs in KVM's emulation of RDPMC (more details on
individual commits) and add a selftest to verify KVM correctly emulates
RDMPC, counter availability, and a variety of other PMC-related
behaviors that depend on guest CPUID and therefore are easier to
validate with selftests than with custom guests (aka kvm-unit-tests).
* Zero out PMU state on AMD if the virtual PMU is disabled, it does not
cause any bug but it wastes time in various cases where KVM would check
if a PMC event needs to be synthesized.
* Optimize triggering of emulated events, with a nice ~10% performance
improvement in VM-Exit microbenchmarks when a vPMU is exposed to the
guest.
* Tighten the check for "PMI in guest" to reduce false positives if an NMI
arrives in the host while KVM is handling an IRQ VM-Exit.
* Fix a bug where KVM would report stale/bogus exit qualification information
when exiting to userspace with an internal error exit code.
* Add a VMX flag in /proc/cpuinfo to report 5-level EPT support.
* Rework TDP MMU root unload, free, and alloc to run with mmu_lock held for
read, e.g. to avoid serializing vCPUs when userspace deletes a memslot.
* Tear down TDP MMU page tables at 4KiB granularity (used to be 1GiB). KVM
doesn't support yielding in the middle of processing a zap, and 1GiB
granularity resulted in multi-millisecond lags that are quite impolite
for CONFIG_PREEMPT kernels.
* Allocate write-tracking metadata on-demand to avoid the memory overhead when
a kernel is built with i915 virtualization support but the workloads use
neither shadow paging nor i915 virtualization.
* Explicitly initialize a variety of on-stack variables in the emulator that
triggered KMSAN false positives.
* Fix the debugregs ABI for 32-bit KVM.
* Rework the "force immediate exit" code so that vendor code ultimately decides
how and when to force the exit, which allowed some optimization for both
Intel and AMD.
* Fix a long-standing bug where kvm_has_noapic_vcpu could be left elevated if
vCPU creation ultimately failed, causing extra unnecessary work.
* Cleanup the logic for checking if the currently loaded vCPU is in-kernel.
* Harden against underflowing the active mmu_notifier invalidation
count, so that "bad" invalidations (usually due to bugs elsehwere in the
kernel) are detected earlier and are less likely to hang the kernel.
x86 Xen emulation:
* Overlay pages can now be cached based on host virtual address,
instead of guest physical addresses. This removes the need to
reconfigure and invalidate the cache if the guest changes the
gpa but the underlying host virtual address remains the same.
* When possible, use a single host TSC value when computing the deadline for
Xen timers in order to improve the accuracy of the timer emulation.
* Inject pending upcall events when the vCPU software-enables its APIC to fix
a bug where an upcall can be lost (and to follow Xen's behavior).
* Fall back to the slow path instead of warning if "fast" IRQ delivery of Xen
events fails, e.g. if the guest has aliased xAPIC IDs.
RISC-V:
* Support exception and interrupt handling in selftests
* New self test for RISC-V architectural timer (Sstc extension)
* New extension support (Ztso, Zacas)
* Support userspace emulation of random number seed CSRs.
ARM:
* Infrastructure for building KVM's trap configuration based on the
architectural features (or lack thereof) advertised in the VM's ID
registers
* Support for mapping vfio-pci BARs as Normal-NC (vaguely similar to
x86's WC) at stage-2, improving the performance of interacting with
assigned devices that can tolerate it
* Conversion of KVM's representation of LPIs to an xarray, utilized to
address serialization some of the serialization on the LPI injection
path
* Support for _architectural_ VHE-only systems, advertised through the
absence of FEAT_E2H0 in the CPU's ID register
* Miscellaneous cleanups, fixes, and spelling corrections to KVM and
selftests
LoongArch:
* Set reserved bits as zero in CPUCFG.
* Start SW timer only when vcpu is blocking.
* Do not restart SW timer when it is expired.
* Remove unnecessary CSR register saving during enter guest.
* Misc cleanups and fixes as usual.
Generic:
* cleanup Kconfig by removing CONFIG_HAVE_KVM, which was basically always
true on all architectures except MIPS (where Kconfig determines the
available depending on CPU capabilities). It is replaced either by
an architecture-dependent symbol for MIPS, and IS_ENABLED(CONFIG_KVM)
everywhere else.
* Factor common "select" statements in common code instead of requiring
each architecture to specify it
* Remove thoroughly obsolete APIs from the uapi headers.
* Move architecture-dependent stuff to uapi/asm/kvm.h
* Always flush the async page fault workqueue when a work item is being
removed, especially during vCPU destruction, to ensure that there are no
workers running in KVM code when all references to KVM-the-module are gone,
i.e. to prevent a very unlikely use-after-free if kvm.ko is unloaded.
* Grab a reference to the VM's mm_struct in the async #PF worker itself instead
of gifting the worker a reference, so that there's no need to remember
to *conditionally* clean up after the worker.
Selftests:
* Reduce boilerplate especially when utilize selftest TAP infrastructure.
* Add basic smoke tests for SEV and SEV-ES, along with a pile of library
support for handling private/encrypted/protected memory.
* Fix benign bugs where tests neglect to close() guest_memfd files.

use-after-free if kvm.ko is unloaded
- Grab a reference to the VM's mm_struct in the async #PF worker
itself instead of gifting the worker a reference, so that there's
no need to remember to *conditionally* clean up after the worker
Selftests:
- Reduce boilerplate especially when utilize selftest TAP
infrastructure
- Add basic smoke tests for SEV and SEV-ES, along with a pile of
library support for handling private/encrypted/protected memory
- Fix benign bugs where tests neglect to close() guest_memfd files"

Devicetree updates for v6.9:
DT core:
- Add cleanup.h based auto release of struct device_node pointers via
__free marking and new for_each_child_of_node_scoped() iterator to use
it.
- Always create a base skeleton DT when CONFIG_OF is enabled. This
supports several usecases of adding DT data on non-DT booted systems.
- Move around some /reserved-memory code in preparation for further
improvements
- Add a stub for_each_property_of_node() for !OF
- Adjust the printk levels on some messages
- Fix __be32 sparse warning
- Drop RESERVEDMEM_OF_DECLARE usage from Freescale qbman driver
(currently orphaned)
- Add Saravana Kannan and drop Frank Rowand as DT maintainers
DT bindings:
- Convert Mediatek timer, Mediatek sysirq, fsl,imx6ul-tsc,
fsl,imx6ul-pinctrl, Atmel AIC, Atmel HLCDC, FPGA region, and
xlnx,sd-fec to DT schemas
- Add existing, but undocumented fsl,imx-anatop binding
- Add bunch of undocumented vendor prefixes used in compatible strings
- Drop obsolete brcm,bcm2835-pm-wdt binding
- Drop obsolete i2c.txt which as been replaced with schema in dtschema
- Add DPS310 device and sort trivial-devices.yaml
- Enable undocumented compatible checks on DT binding examples
- More QCom maintainer fixes/updates
- Updates to writing-schema.rst and DT submitting-patches.rst to cover
some frequent review comments
- Clean-up SPDX tags to use 'OR' rather than 'or'

MTD
The Carillo Ranch driver has been removed. Top level mtd bindings have
received a couple of improvements (references, selects). The ssfdc
driver received few minor adjustments. These changes come with the usual
load of misc/small improvements and fixes.
Raw NAND
The main series brought is an update of the Broadcom support to support
all BCMBCA SoCs and their specificity (ECC, write protection,
configuration straps), plus a few misc fixes and changes in the main
driver. Device tree updates are also part of this PR, initially because
of a misunderstanding on my side.
The STM32_FMC2 controller driver is also upgraded to properly support
MP1 and MP25 SoCs.
A new compatible is added for an Atmel flavor.
Among all these feature changes, there is as well a load of continuous
read related fixes, avoiding more corner conditions and clarifying the
logic. Finally a few miscellaneous fixes are made to the core, the
lpx32xx_mlc, fsl_lbc, Meson and Atmel controller driver, as well as
final one in the Hynix vendor driver.
SPI-NAND
The ESMT support has been extended to match 5 bytes ID to avoid
collisions. Winbond support on its side receives support for W25N04KV
chips.
SPI NOR
SPI NOR gets the non uniform erase code cleaned. We stopped using
bitmasks for erase types and flags, and instead introduced dedicated
members. We then passed the SPI NOR erase map to MTD. Users can now
determine the erase regions and make informed decisions on partitions
size.
An optional interrupt property is now described in the bindings.
