smb/client: invalidate fscache for fallocate range operations
smb3_zero_range(), smb3_punch_hole(), smb3_insert_range(), and
smb3_collapse_range() modify file contents through server-side range
operations. These operations discard the affected page cache, but leave
the FS-Cache cookie valid, so a later read may return data cached before
the range operation.
Fix this by invalidating FS-Cache after outstanding I/O has completed
and before modifying the file on the server.
Run the following as root on a CIFS mount with fsc enabled and an active
CacheFiles backend:
bash -c '
MNT=/mnt/cifs
FILE="$MNT/repro"
# Generate four 1 MiB random blocks: [A][B][C][D].
dd if=/dev/urandom of=/tmp/src bs=1M count=4 status=none
# Expected contents after zeroing B: [A][zero][C][D].
cp /tmp/src /tmp/expected
dd if=/dev/zero of=/tmp/expected bs=1M seek=1 count=1 \
conv=notrunc status=none
cp /tmp/src "$FILE"
# Populate FS-Cache, then discard the page cache.
sync
echo 1 > /proc/sys/vm/drop_caches
cat "$FILE" > /dev/null
sync
echo 1 > /proc/sys/vm/drop_caches
fallocate --zero-range -o 1M -l 1M "$FILE"
if cmp -s /tmp/expected "$FILE"; then
echo "readback: OK"
else
echo "readback: STALE DATA"
fi
'
Before this change, the readback differs from /tmp/expected:
readback: STALE DATA
After this change, it matches:
readback: OK

smb/client: fix stale page cache in insert/collapse range
smb3_insert_range() and smb3_collapse_range() use
truncate_pagecache_range() to invalidate the affected page cache.
However, if off or old_eof is not page-aligned, the boundary pages are
only partially zeroed and remain uptodate. As a result, the client may
return stale data after a successful insert/collapse range operation.
For example, with 4K pages:
page 0 page 1 page 2
0------4K 4K------8K 8K------12K
^ ^
off=2K old_eof=10K
Page 1 is removed from the page cache, while the boundary pages are
only partially zeroed. After COPYCHUNK moves the data on the server,
these cached pages may still return stale data.
This can be reproduced on a CIFS mount:
bash -c '
FILE=/mnt/scratch/repro
# Use a 6 KiB file so EOF is not page-aligned.
dd if=/dev/urandom of=/tmp/src bs=1K count=6 status=none
# Expected: a 4 KiB hole followed by the original data.
rm -f /tmp/expected
truncate -s 4K /tmp/expected
cat /tmp/src >> /tmp/expected
cp /tmp/src "$FILE"
# Prime the page cache before moving data on the server.
cat "$FILE" > /dev/null
fallocate --insert-range -o 0 -l 4K "$FILE"
if cmp -s /tmp/expected "$FILE"; then
echo "readback: OK"
else
echo "readback: STALE DATA"
fi
'
Fix this by writing back dirty data and discarding the page cache from
the start of the page containing off to EOF before moving data on the
server.

smb/client: fix integer truncation in collapse range
smb3_collapse_range() stores the ssize_t return value of
smb2_copychunk_range() in an int. A successful copy larger than
INT_MAX is truncated to a negative value and treated as an error.
Reproducer:
MNT=/mnt/scratch
truncate -s 2056M "$MNT/file"
fallocate --collapse-range -o 1M -l 1M "$MNT/file"
Fix this by using __smb2_copychunk_range(), which reports success as
zero instead of returning the copied byte count.
Before this change, the reproducer fails with:
fallocate: fallocate failed: Success
and the file size remains unchanged at 2056 MiB. After this change, the
reproducer succeeds and the file size becomes the expected 2055 MiB.

smb/client: fix data corruption in emulated insert range
smb3_insert_range() shifts [off, EOF) right with COPYCHUNK, copying from
low to high offsets. When the ranges overlap, the copy can overwrite
source data that has not yet been copied. For a 1 MiB insert at offset 0:
offset: 0 1M 2M 3M 4M 5M
before: | A | B | C | D |
expected: | hole | A | B | C | D |
current: | hole | A | A | A | A | (corrupted)
Let x be the insertion offset, L the total length to move, delta the
insert length, and C the normal chunk size allowed by the server.
Insert range maps
[x, x + L) -> [x + delta, x + delta + L).
When delta >= L, the complete source and target ranges are disjoint, so
the normal copy order and chunk size are safe:
offset: 0 4 8 12 16 20 24 28 32
source: [--S0--][--S1--][--S2--][--S3--]
target: [--T0--][--T1--][--T2--][--T3--]
When delta < L, the complete source and target ranges overlap, so the
copy must proceed from EOF backwards. There are two subcases.
If delta >= C, each corresponding source and target chunk is disjoint.
The 1 MiB example has L = 4 MiB and delta = C = 1 MiB:
offset: 0 1M 2M 3M 4M 5M
source: [--S0--][--S1--][--S2--][--S3--]
target: [--T0--][--T1--][--T2--][--T3--]
Copying S0 from [0, 1M) to [1M, 2M) overwrites S1 before it is copied.
Processing chunks from EOF backwards prevents this inter-chunk
overwrite.
If delta < C, the source and target ranges of a normal chunk also
overlap. For example, with L = 16, delta = 2 and C = 4:
offset: 0 2 4 6 8 10 12 14 16 18
source: [--S0--][--S1--][--S2--][--S3--]
target: [--T0--][--T1--][--T2--][--T3--]
Here S0 and T0 overlap over [2,4), S1 and T1 over [6,8), and so on.
Backward ordering cannot control how the server copies bytes inside one
descriptor, so the chunk size must be limited to delta.
Fix this by copying overlapping right shifts from EOF backwards. Limit
the chunk size to delta when delta < C so that each chunk's source and
target ranges do not overlap. Using larger chunks would require a way to
identify servers that safely handle overlapping COPYCHUNK descriptors.
Therefore:
delta >= L:
keep the normal copy order and chunk size
delta < L:
delta >= C: copy backwards and keep the normal chunk size
delta < C: copy backwards and limit the chunk size to delta
Only the delta < C subcase requires reducing the chunk size for data
integrity.
Reproducer:
bash -c '
MNT=/mnt/scratch
# Generate four 1 MiB random blocks: [A][B][C][D].
dd if=/dev/urandom of=/tmp/src bs=1M count=4 status=none
# With C = 1 MiB, test delta = C and delta < C.
for delta in 1M 1K; do
truncate -s 0 /tmp/expected
truncate -s "$delta" /tmp/expected
cat /tmp/src >> /tmp/expected
cp /tmp/src "$MNT/file"
fallocate --insert-range -o 0 -l "$delta" "$MNT/file"
if cmp -s /tmp/expected "$MNT/file"; then
echo "delta=$delta: OK"
else
echo "delta=$delta: CORRUPTED"
fi
done
'
The corruption reproduces with Samba and ksmbd, while Windows handles
the overlapping COPYCHUNK ranges safely.
The 1 MiB case tests delta >= C, while the 1 KiB case tests delta < C.
Before this change, the reproducer reports:
delta=1M: CORRUPTED
delta=1K: CORRUPTED
After this change, it passes against both ksmbd and Samba:
delta=1M: OK
delta=1K: OK

smb/client: mark file sparse before emulating insert range
The SMB client emulates FALLOC_FL_INSERT_RANGE with SET_EOF, COPYCHUNK
and SET_ZERO_DATA.
SET_ZERO_DATA creates a hole only when the file is sparse. On a
non-sparse file, it clears the inserted range but leaves its blocks
allocated, causing the extent count check in xfstests generic/064 to
fail.
Fix this by marking the file sparse before modifying it.
This patch produces the expected sparse extents in xfstests generic/064
only when the server-reported block size is compatible with the server's
deallocation granularity.
For ksmbd, the reported block size follows the backing filesystem,
and the test passes. For Samba, the test passes with a block size
matching the backend granularity, for example, 4 KiB on Btrfs, but not
with the default 1 KiB value. For Windows Server 2022, 4 KiB inserts do
not generate holes, while aligned inserts of 64 KiB or larger do.

smb/client: validate new EOF for zero range
When FALLOC_FL_ZERO_RANGE is used without FALLOC_FL_KEEP_SIZE,
smb3_zero_range() may extend EOF without checking RLIMIT_FSIZE, allowing
the file to grow beyond the caller's file-size limit.
Fix this by calling inode_newsize_ok() before sending the zero-range
request when the operation would extend EOF.
Reproducer, using a file on a CIFS mount:
bash -c '
FILE=/mnt/cifs/repro
trap "" SIGXFSZ
ulimit -f 3072
truncate -s 2M "$FILE"
fallocate --zero-range -o 0 -l 4M "$FILE"
echo "fallocate rc=$?"
stat -c "file size=%s" "$FILE"
'
Before this change, the operation succeeds despite the 3 MiB limit:
fallocate rc=0
file size=4194304
After this change, fallocate fails and leaves the file at 2 MiB.

smb/client: validate new EOF for insert range
smb3_insert_range() does not check if the new file size
(i_size + len) is valid. This allows FALLOC_FL_INSERT_RANGE to bypass
RLIMIT_FSIZE, exceed s_maxbytes, or produce a size outside the loff_t
range.
Use check_add_overflow() to calculate the new EOF. Validate it with
inode_newsize_ok() before modifying the file.
Reproducer, using a file on a CIFS mount:
bash -c '
FILE=/mnt/cifs/repro
trap "" SIGXFSZ
ulimit -f 3072 # RLIMIT_FSIZE = 3 MiB
# A regular write is stopped at 3 MiB.
dd if=/dev/zero of="$FILE" bs=1M count=4 status=none
stat -c "size after write: %s" "$FILE"
# Insert 2 MiB into a 2 MiB file.
truncate -s 2M "$FILE"
fallocate -i -o 0 -l 2M "$FILE"
stat -c "size after insert: %s" "$FILE"
'
Before this change, the regular write stops at the 3 MiB limit, but
insert range grows the file to 4 MiB:
dd: error writing '/mnt/cifs/repro': File too large
size after write: 3145728
size after insert: 4194304
After this change, insert range also fails at the limit and leaves the
2 MiB file unchanged:
dd: error writing '/mnt/cifs/repro': File too large
size after write: 3145728
fallocate: fallocate failed: File too large
size after insert: 2097152

cifs: add revalidation on FSCTL failure in smb2_duplicate_extents()
smb2_duplicate_extents() has no handling for
FSCTL_DUPLICATE_EXTENTS_TO_FILE failure: when the FSCTL fails, local
inode metadata may be stale from the pre-extension or from concurrent
remote writes, but is never refreshed.
Force revalidation on FSCTL failure and use i_size_read() for the
pre-extension check.

remoteproc updates for v7.3
Add a remoteproc driver and binding for AMD MicroBlaze/V soft cores executing from dual-port BRAM, with clock and reset control and support for firmware without a resource table. Introduce a generic Qualcomm PAS service with SCM and OP-TEE backends, and migrate the PAS, MSS, and WCNSS remoteproc drivers to it. Add Nord ADSP and CDSP support, Eliza CDSP support, Maili ADSP/CDSP bindings, and late-attach SoCCP support for Kaanapali, Hawi, Maili, and Glymur. Enable BAM-DMUX child devices for PAS modems and fix PAS memory protection, handover, shutdown, and resource lifetime handling. Harden remoteproc lifecycle handling by attaching asynchronously, stopping crashed processors, synchronizing crash work with removal, and forcing shutdown before device resources are released. Reallocate resources during attach recovery and fix several reference and error-path leaks. Add Xilinx R5 crash detection and move RPU start and stop sequencing into the platform firmware driver. Consolidate write-combining carveout mapping callbacks, use correct I/O-memory accessors, and share optional ELF resource-table handling across drivers. Convert the TI Wakeup M3 binding to DT schema, correct Qualcomm and generic remoteproc bindings, and harden resource-table iteration against signed-offset out-of-bounds accesses. -----BEGIN PGP SIGNATURE----- iQJCBAABCgAsFiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAmqN/FgOHGJqb3JuQGty eW8uc2UACgkQCx85Pw2ZrcUvXRAAkCk6ogZOdjGY9WBugieN3WEfkAzrWAS9ntWK CGR+VcL633ymLtS/6E2fdv4d7Uh1An/ipcCJUSXU4CzumB7O1FJi1CfQok2j+4xz dIBc9m6SAMYBFVLAXD2NujdOf+nwEDLbJQib7lVBTBCNjQamvjFhUu9g/bnJt4gT F1ieAgNP15OFfHnoSWhoFHXI8ao4Vs0PwfoBLEwIP5VuFXy3DzVGaqEZgEgD7+G5 Qy0ii/TO+EFC8GdK8xxlCtKYT6J3qG/pQBaCtS9QwSXNPTbI31MlDimInUl7lxHS yWeDOJPVgNL279W7DnHiELQT6uGFac+1ILNBIGl9lI1+4Hcwgg6eTwwP6wcIOhYL YFXNfCeb5XW6moOKxhkcbOwZ46/FUS4sywoUyaAevFOc8kisDwMy81C1d2cYVg12 gq69ah4sWkSPSkAgOeUf8Aa8v3eXj9IaxcIAW9+fQdNaduuG7oRvVzowKbli9SiD qAAaIV2wyt+Il7VJl5Nw1R0nJONMTK44Xft+3k/TFzmr5N1ivfSBvGxIg0zdB9xZ 7akukQjCJgWOcyICa3ShyA6foClsJF26xVhQrfY7UPKI7DQHY5GQAKgpA2zWrqH5 cKt5xRcImKn+788pfkNdVj8IxROjGEI5JXf6etIvpPnUzkFG3nZfY6kLryOxvv0H zyxm4OM= =wi8c -----END PGP SIGNATURE----- Merge tag 'rproc-v7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux Pull remoteproc updates from Bjorn Andersson: "Add a remoteproc driver and binding for AMD MicroBlaze/V soft cores executing from dual-port BRAM, with clock and reset control and support for firmware without a resource table.

compels the user to select a specific PMU implementation
* Lazy save/restore of vCPU state for pKVM, along with various fixes
and cleanups to the management of vCPU state between the untrusted
host and pKVM hypervisor
* Disable traps of EL1 registers for nested hypervisors when FEAT_NV2p1
is present, guaranteeing that EL2-specific register bits are stateful
in the EL1 counterpart
* Leverage FEAT_NV3 to avoid unnecessary ERET/TLBI traps when the scope
of those instructions remains 'in host' (i.e. L1 kernel/userspace)
* Pile of fixes for the management of the VNCR pseudo-TLB, such as
under-invalidations and races with concurrent TLBIs on other vCPUs
* Consolidate the non-protected and pKVM view of ICH_VTR_EL2 to a
runtime-patched constant, allowing the same data to be shared with
pKVM prior to dropping host privileges
* Considerable pile of LLM-assisted fixes around the shop but mostly in
the VGIC, our in-kernel generator of bugs (and sometimes interrupts)
LoongArch:
* Advertise already-supported capabilities.
* Some bug fixes about timer and MMIO.
* Some hardening about interrupt injection.
* Replace kvm_err() with kvm_pr_unimpl().
* Add FPU/LSX/LASX test cases for selftests.
RISC-V:
* Svadu/Zicfiss/Zicfilp FWFT support for Guest
* Use try_cmpxchg for IMSIC MRIF RMW
* More arch-specific tracepoints in KVM RISC-V
* Eager page splitting when enabling dirty logging
* Optimize hfence request handling for SMP Guests
* Improve dirty log clearing by skipping zero bits in mask
* Guard HFENCE range loops against overflow
* CPU PM notifiers in KVM RISC-V for non-retentive idle states
* Fix kernel-mode vector context save/restore for Guest
s390:
* Fixes for vfio-ap
* Fixes for the gmap rework
* Fixes for vsie
* AI triggered fixes all over
* diag9c tracing
* code move preparation for the additional arm64 support
* enable CONTEXT_ANALYSIS
x86:
* Perform spring cleaning on x86.{c,h} and asm/kvm_host.h, by adding regs.c
(the kvm_cache_regs.h => regs.h is already applied) and msrs.{c,h}, and moving
relevant code out of x86.c.
* Split kvm_mmu in three parts, respectively to describe the format of page
tables, walking the guest page tables and building the page tables. Always
use the same page table walker kvm->arch.gva_walk as the entry point to
convert a guest's virtual address, where the previous code used two
different kvm_mmu structs depending on whether the walk included nested
EPT/NPT or not. Make page fault vmexits reuse the permission checking
machinery that is used for guest page faults. This is both a cleanup
and a baby step towards supporting XS/XU memory permissions.
* Document some of the "fun" gotchas with the APIC base when creating IRQCHIPs
on x86.
* Remove a defunct masterclock update from kvm_xen_shared_info_init(). It
could result in incorrect kvmclock due to triggering an unnecessary
switch to/from masterclock mode.
* Skip Xen runstate time updates if time has effectively gone backwards, so
that the guest doesn't report 100% steal time for a very, very long time.
* Drop KVM's runtime updates of the Xen PV timing CPUID leaf, as KVM was
updating the wrong sub-leaf, and upstream KVM will soon provide all the
information needed by userspace to populate the CPUID field itself.
* Fix a bug where KVM would walk a newly created rmap without holding the rmap
lock (or mmu_lock) during aging.
* Fix a bug where aging TDP MMU SPTEs could clobber FROZEN SPTEs.
* Fix a variety of #DB priority bugs.
* Fix a class of races related to enabling Hyper-V emulation on a vCPU after
the vCPU is visible to the rest of KVM.
* Use static calls for nested virtualization ops.
* Move more KVM-internal code out of x86's kvm_host.h.
* Enumerate support for a variety of Zhaoxin instructions that don't require
explicit virtualization.
* Fix missing EFER validation bugs, including in the KVM_SET_SREGS* path.
* Harden kvm_vcpu_map() against double-mapping and thus leaking references.
* Misc fixes and cleanups, e.g. for largely benign syzkaller splats.
x86 (Intel):
* Zero a vCPU's entry in VMX's Posted Interrupt Descriptor table used for IPI
virtualization when the vCPU is freed, to fix a use-after-free where hardware
will write to a freed vCPU's PID.
* Service local TLB flushes on a failed nested VM-Enter to fix a bug where KVM
could miss a TLB on a future, successful VM-Enter with the same L2 VPID.
* Cap the maximum value shoved into the VMX Preemption Timer to workaround an
erratum that affects all existing Intel CPUs that support CPUID 0x15.
* Fix VPID virtualization bugs where KVM would fail to flush hardware TLBs.
* Harden the TDX "populate" ioctls against bad input, and to prepare
for supporting in-place private<=>shared conversion.
x86 (AMD):
* Forcefully invalidate SNP VMSA pages if their backing guest_memfd page is
zapped/invalidated, e.g. due to a PUNCH_HOLE in response to a Page-State
Change request.
* Remove a dying VM from the GA Log notifier list before the VM is actually
destroyed, to fix a potential use-after-free.
* While FOLL_WRITE was needed in the past to trigger CoW unsharing, nowadays
FOLL_LONGTERM does that already even without FOLL_WRITE, and in fact,
get_user_pages() actually disallows FOLL_WRITE together with FOLL_LONGTERM.
So don't pass FOLL_WRITE when registering encrypted memory regions, i.e. when
pinning SEV/SEV-ES guest memory, to fix a regression with file-backed memory
introduced by KVM's (correct) usage of long-term pins.

Char/Misc/IIO/etc driver update for 7.3-rc1
Here is the big set of char, misc, iio, counter, fpga, and other small
driver subsystems for 7.3-rc1.
Overall, due to some driver removals we only added a bit more code than
removed, which was a nice change. Highlights in this merge request are:
- Loads of IIO driver updates and additions
- binder driver updates (more on that below...)
- Removal of the SGI XP and GRU drivers as they are not used anymore
and turn out to be pretty insecure overall
- Removal of the obsolete ibmasm driver as it's not being used anymore
- Coresight driver updates and additions
- Mei driver udpates
- Counter driver updates
- FPGA driver updates
- ICC driver updates
- lots and lots of other tiny driver updates to resolve reported
issues
All of these have been in linux-next for a while, with the only reported
issues being some major merge conflicts. Miguel pointed out some of
these with the Rust tree merge, which is the majority of them. I'll
follow up with a diffstat of the merge resolution I made against your
most recent tree, which works for me.

Bootconfig updates for v7.3:
- bootconfig: Support build-time command line rendering for embedded bootconfig
. bootconfig: render descendant keys when xbc_snprint_cmdline() root has a
value. Fix xbc_snprint_cmdline() to render descendant keys when the root
has both a value and subkeys, and treats empty subtrees correctly.
. bootconfig: render embedded bootconfig as a kernel cmdline at build time.
Add build-time pipeline using tools/bootconfig -C to render the embedded
bootconfig "kernel" subtree into .init.rodata as a cmdline string.
. bootconfig: clean build-time tools/bootconfig from make clean.
. bootconfig: add xbc_prepend_embedded_cmdline() helper.
Add helper to prepend embedded bootconfig cmdline into boot_command_line
early before parse_early_param().
. x86/setup: prepend embedded bootconfig cmdline before parse_early_param.
Wire early prepend helper in x86 setup_arch() so early_param handlers see
values from the embedded bootconfig. (So this feature is currently x86 only)
. bootconfig: skip runtime kernel.* render once prepended early.
Avoid duplicating "kernel" keys in setup_boot_config().
. init/main.c: use bootconfig_cmdline_requested() for the runtime opt-in.

This contains 52 commits with improvements to compression support,
metadata handling, error propagation, and filesystem robustness.
New feature:
- Add optional read support for Windows System Compression (WOF).
Add CONFIG_NTFS_FS_WOF_COMPRESSION and support reading WOF-compressed
files through the NTFS page-read path. This includes parsing
REPARSE_TAG_WOF, handling resident and non-resident WOF metadata and
compressed chunks, and adding kernel-side XPRESS 4K/8K/16K and LZX 32K
decompressors. The codecs use a common transparent compression interface
shared with LZNT1. WOF support is read-only and disabled unless
explicitly enabled.
Other changes:
- Harden malformed filesystem handling and error paths.
Add bounds and consistency checks for mapping pairs, run lengths, MFT
locations, update-sequence offsets, non-resident attributes, compressed
attributes, index roots, and bitmap scans. Prevent out-of-bounds accesses
in decompression, MFT allocation, and index conversion paths, clean up MFT
mappings and attribute search contexts on failure, and propagate attribute
and inode initialization errors correctly.
- Improve compressed-file I/O path.
Fix compressed writes on large-page and highmem systems, reuse compression
contexts and output workspaces, avoid unnecessary reads for full-unit
overwrites, and submit one bio per compressed write unit. Write replacement
data before publishing the new mapping, correctly handle zero-filled
compressed blocks, and fix initialized-size and folio state updates after
compressed writes.
- Synchronize resident reads with MFT record updates.
- Validate the final EA stream size before modifying existing data, rewrite
the stream safely when replacing entries, restore the previous state when
metadata updates fail, and remove the EA attribute pair when the last
entry is deleted.
- Apply Windows filename restrictions only when windows_names is enabled.
- Allow index roots to relocate to extent MFT records when the base record
lacks sufficient space.
- Move non-resident attribute payload data before shrinking its record.
- Correct resident-to-non-resident conversion when compression or sparse
flags are enabled.
- Prepare file allocation and initialized-size updates before buffered or
direct I/O submission, and use pagecache_isize_extended() when extending
the file size.
- Fix highmem and page/folio access in compressed I/O paths by using the
correct local mappings and page helpers.
- Apply per-file $LXMOD permissions instead of mount masks when available,
and prevent unprivileged writes to reserved $LX* attributes.
- Update the NTFS maintainer mailing list.
- Four small cleanups.

Add bounds and consistency checks for mapping pairs, run lengths,
MFT locations, update-sequence offsets, non-resident attributes,
compressed attributes, index roots, and bitmap scans. Prevent
out-of-bounds accesses in decompression, MFT allocation, and index
conversion paths, clean up MFT mappings and attribute search
contexts on failure, and propagate attribute and inode
initialization errors correctly.
- Improve compressed-file I/O path.
Fix compressed writes on large-page and highmem systems, reuse
compression contexts and output workspaces, avoid unnecessary reads
for full-unit overwrites, and submit one bio per compressed write
unit. Write replacement data before publishing the new mapping,
correctly handle zero-filled compressed blocks, and fix
initialized-size and folio state updates after compressed writes.
- Synchronize resident reads with MFT record updates.
- Validate the final EA stream size before modifying existing data,
rewrite the stream safely when replacing entries, restore the
previous state when metadata updates fail, and remove the EA
attribute pair when the last entry is deleted.
- Apply Windows filename restrictions only when windows_names is
enabled.
- Allow index roots to relocate to extent MFT records when the base
record lacks sufficient space.
- Move non-resident attribute payload data before shrinking its
record.
- Correct resident-to-non-resident conversion when compression or
sparse flags are enabled.
- Prepare file allocation and initialized-size updates before
buffered or direct I/O submission, and use
pagecache_isize_extended() when extending the file size.
- Fix highmem and page/folio access in compressed I/O paths by using
the correct local mappings and page helpers.
- Apply per-file $LXMOD permissions instead of mount masks when
available, and prevent unprivileged writes to reserved $LX*
attributes
- Update the NTFS maintainer mailing list
- Small cleanups"

cifs: fix loff_t underflow in cifs_remap_file_range() when len == 0
With len == 0 (clone to EOF), the effective length is computed as:
len = src_inode->i_size - off;
If off > i_size, this is a negative loff_t, corrupting the ByteCount
in the FSCTL_DUPLICATE_EXTENTS_TO_FILE request and inverting the range
in filemap_write_and_wait_range(). The existing off >= i_size check
fires only after the ioctl has already been sent.
Snapshot i_size_read() once for both the bounds check and the length
calculation, eliminating the TOCTOU and 32-bit torn-read risk. Reject
off > src_size with -EINVAL. Treat off == src_size as a no-op,
consistent with __generic_remap_file_range_prep().

smb: client: reject a tree connect response whose byte count is too small
CIFSTCon() bounds its strnlen() over the byte area with the server's
ByteCount minus two, which for ByteCount 0 or 1 goes negative as an int
and converts to a huge size_t. The later subtraction wraps the __u16
bytes_left, and that is what bounds cifs_strndup_from_utf16(): a bound of
up to 65535 against a ~16 KB cifs_req_poolp object runs off the end of the
slab object, and the bytes reach userspace through tcon->nativeFileSystem
in /proc/fs/cifs/DebugData.
Reject a byte area too small for what the parser consumes. Two bytes is
the least it can consume, and no conformant response carries fewer. The
new trace point is the 129th smb_eio_trace entry, which __mode(byte)
cannot represent, so the attribute goes with it.

cifs: call pagecache_isize_extended() in cifs_setsize() when extending
cifs_setsize() calls truncate_pagecache() but skips
pagecache_isize_extended() on extension. truncate_setsize() shows
the correct pattern:
i_size_write(inode, newsize);
if (newsize > oldsize)
pagecache_isize_extended(inode, oldsize, newsize);
truncate_pagecache(inode, newsize);
pagecache_isize_extended() zeroes the tail of the page straddling old
EOF. Without it, dirty bytes in that region can be written back to
the server, exposing stale data in the newly extended range.

cifs: clear tcon after cifsFileInfo_put() in cifs_file_set_size()
When the else branch of cifs_file_set_size() finds a writable file handle
via find_writable_file(), it borrows tcon and server from the handle's
tlink, attempts the handle-based set_file_size() RPC, and then releases
the handle with cifsFileInfo_put().
If set_file_size() fails, execution falls through to the path-based
fallback, which reuses the borrowed tcon and server under the
"if (tcon == NULL)" guard. Since tcon is not NULL at that point, the
guard is skipped. If cifsFileInfo_put() dropped the last reference on a
tlink that was already removed from the tlink tree (TCON_LINK_IN_TREE
cleared, as happens during reconnection or session teardown),
cifs_put_tlink() will have freed tcon; the subsequent set_path_size()
call is then a use-after-free.
Setting tcon = NULL after cifsFileInfo_put() causes the existing guard
to take the cifs_sb_tlink() path, which acquires a fresh reference for
the path-based operation or fails cleanly if the session is gone.

smb: client: fix use-before-check of ReparseDataLength in reparse_buf_ptr()
reparse_buf_ptr() reads buf->ReparseDataLength before checking that
count covers the full fixed header:
buf = (struct reparse_data_buffer *)((u8 *)io + off);
len = sizeof(*buf); /* 8 bytes */
rdlen = le16_to_cpu(buf->ReparseDataLength); /* offset 4, 2 bytes */
if (count < len || count < rdlen + len) /* check comes after */
struct reparse_data_buffer has ReparseDataLength at offset 4. If a
server returns OutputCount < 6, the read at offset 4-5 reaches past
the end of the received data. The off+count bounds against iov_len
were already validated, but that does not protect against count being
smaller than sizeof(*buf).
Split the check: verify count >= sizeof(*buf) before reading
ReparseDataLength, then verify count covers the data region.

smb: client: fix UAF and buffer leak in cifs_check_trans2() for malformed secondary T2
When a valid primary TRANSACT2 response has been received (mid->resp_buf
set, mid->multiRsp true) and a subsequent secondary response causes
cifs_check_trans2() to return false -- either because the SMB header is
invalid (malformed != 0) or because check2ndT2() rejects the PDU --
handle_mid() overwrites mid->resp_buf with the new buffer (leaking the
primary buffer) and, because mid->multiRsp is set, skips the
server->smallbuf/bigbuf NULL-out. When the user thread frees
mid->resp_buf, server->smallbuf or server->bigbuf is left dangling; the
demux thread reuses it for the next packet, resulting in a use-after-free.
Combine both early-exit conditions and, when mid->multiRsp is already
set, abort the pending transaction inline: set multiEnd, call
dequeue_mid() with malformed=true, and return true so handle_mid() exits
without touching mid->resp_buf or the server buffer pointers.

smb: client: fix OOB read/write from unvalidated DataOffset in coalesce_t2()
coalesce_t2() computes data pointers directly from server-supplied
DataOffset fields with no validation against buffer bounds:
data_area_of_tgt = (char *)&pSMBt->hdr.Protocol +
get_unaligned_le16(&pSMBt->t2_rsp.DataOffset);
data_area_of_src = (char *)&pSMBs->hdr.Protocol +
get_unaligned_le16(&pSMBs->t2_rsp.DataOffset);
data_area_of_tgt += total_in_tgt;
...
memcpy(data_area_of_tgt, data_area_of_src, total_in_src);
A small DataOffset can push a pointer below the actual byte area,
overwriting header fields; a large one can push it past the buffer
end, causing out-of-bounds heap reads (source) or writes (target).
The BCC overflow guard does not prevent this: BCC reflects how much
data is present, while DataOffset controls where in the buffer it
starts.
The "validate target area" comment present since the function was
first written in 2005 was a placeholder that was never implemented.
Add lower- and upper-bound checks for both data pointers before the
memcpy, and before any target header fields are modified.

smb/client: decode reparse metadata using its payload type
cifs_open_info_data stores FILE_ALL_INFORMATION and SMB3 POSIX query
information in a union. reparse_info_to_fattr() selects a union member
from the mount mode, while several directory checks always read
fi.Attributes.
The metadata can instead come from an SMB2 CREATE response on a POSIX
mount, or from a POSIX query while processing a reparse point. In those
cases the mount mode and hard-coded fi accesses select the wrong union
member.
See the procedures below:
cifs_nt_open
smb2_open_file
SMB2_open
data->fi = SMB2 CREATE response
data->contains_posix_file_info = false
cifs_get_inode_info
reparse_info_to_fattr
if (tcon->posix_extensions) // true
smb311_posix_info_to_fattr
data->posix_fi // wrong union member
smb311_posix_get_fattr
smb2_query_path_info
smb2_compound_op
data->posix_fi = SMB3 POSIX query response
data->contains_posix_file_info = true
reparse_info_to_fattr
data->fi.Attributes // wrong union member
Add a common DOS attribute accessor and use contains_posix_file_info
both for attribute reads and for the final fattr conversion.

smb/client: preserve open info type across compound queries
contains_posix_file_info describes the metadata stored in the
fi/posix_fi union. GET_REPARSE and QUERY_WSL_EA do not update that
union, so clearing the flag while processing those responses can make
POSIX metadata look like FILE_ALL_INFORMATION.
Set the flag when CREATE or a validated query response actually
populates the union, and leave it unchanged for auxiliary compound
operations. This also avoids changing the type when a query fails
before copying any metadata.
The issue can be reproduced against a Samba server with SMB3 UNIX
extensions enabled:
mount -t cifs //<server>/<share> /mnt/cifs \
-o vers=3.1.1,posix,reparse=nfs,actimeo=0
mkfifo /mnt/cifs/test-fifo
umount /mnt/cifs
mount -t cifs //<server>/<share> /mnt/cifs \
-o vers=3.1.1,posix,reparse=nfs,actimeo=0
stat -c '%F %s' /mnt/cifs/test-fifo
Before this change, stat reports "fifo 1024" although the server-side
EOF is zero. After this change, it reports "fifo 0".

smb/client: mark missing nlink values as unknown
Several SMB1 fallback and open responses do not provide the hard link
count. The SMB2 create-only query fallback has the same limitation.
These paths currently leave a zero link count or synthesize a value of
one and then expose it as authoritative metadata.
Mark those results with unknown_nlink so existing inodes keep their
cached link count and new inodes receive the usual sane default.
This was tested against Samba with "server min protocol = NT1". Mount
the share using SMB1 with Unix extensions disabled:
mount -t cifs //<server>/<share> /mnt/cifs \
-o username=<user>,vers=1.0,nounix
Create three names for the same inode and cache its real link count:
TESTDIR=/mnt/cifs/nlink-repro-$$
mkdir "$TESTDIR"
touch "$TESTDIR/file1"
ln "$TESTDIR/file1" "$TESTDIR/file2"
ln "$TESTDIR/file1" "$TESTDIR/file3"
stat -c 'before open: %h' "$TESTDIR/file1"
Open the file and read the link count through the open descriptor:
exec 3<"$TESTDIR/file1"
stat -Lc 'after open: %h' /proc/$$/fd/3
exec 3<&-
Clean up the test files:
rm -f "$TESTDIR/file1" "$TESTDIR/file2" "$TESTDIR/file3"
rmdir "$TESTDIR"
Before this change, the two stat commands report 3 and 1 because the
SMB1 open response overwrites the known link count. With this change,
both commands report 3.
