ntfs: fix resident conversion in ntfs_new_attr_flags
When setting sparse/compressed flags on a resident attribute, the function skipped the resident-to-non-resident conversion and terminated. Signed-off-by: Hyunchul Lee <hyc.lee@gmail.com> Signed-off-by: Namjae Jeon <linkinjeon@kernel.org> |

ntfs: skip reads for full compression unit overwrites
ntfs_compress_write() reads every page in a compression unit before copying new data into it. The read is unnecessary when an aligned write replaces every byte covered by the page-cache folios. Detect full page-aligned compression unit overwrites and grab locked cache folios without reading them. Keep the read-modify-write path for partial units and units that cover only part of a large page. Reviewed-by: Hyunchul Lee <hyc.lee@gmail.com> Signed-off-by: Namjae Jeon <linkinjeon@kernel.org> |

ntfs: submit one bio per compressed write unit
ntfs_write_cb() allocates a single-vector bio and synchronously submits it whenever another output page cannot be added. A 64 KiB uncompressed unit therefore requires up to sixteen separate bio submissions. Allocate enough vectors for the complete unit, add all output pages, and perform one synchronous submission.

ntfs: reuse compression output workspace across write units
ntfs_write_cb() allocates output pages and creates input and output vmaps for every compression unit. Sequential writes repeatedly pay those allocation and page-table costs even though each unit has the same maximum output size. Allocate and map the output workspace once per write request. Access input sub-blocks with kmap_local_page(), and reuse the output pages and mapping for every compression unit in the request.

ntfs: reuse the compression context during writes
ntfs_compress_block() allocates and initializes a roughly 40 KiB match finder context for every 4 KiB sub-block. A 64 KiB compression unit thus performs sixteen large allocations even though the calls are serialized. Allocate one context for the complete write request and reset its hash chains for each sub-block as before.

ntfs: fix initialized size and page state after compressed writes
The write iterator now expands attributes before calling ntfs_compress_write(), so compressed writes must not expand the attribute themselves. However, the compressed path still needs to reject zero-byte iterator copies, advance initialized_size after successful I/O, and invalidate modified folios after a failed compression-unit write. Reject no-progress copies, persist the new initialized size on success, and clear folio uptodate state when the synchronous write fails.

ntfs: write compressed data before replacing old clusters
ntfs_write_cb() punches the old compression unit and publishes the new mapping before submitting the replacement data. An allocation or I/O failure after the punch loses the previous contents and can leave the mapping pointing at unwritten clusters. Allocate and write the replacement clusters first. Replace the runlist only after the synchronous write succeeds, and free new clusters on failure. Reviewed-by: Hyunchul Lee <hyc.lee@gmail.com> Signed-off-by: Namjae Jeon <linkinjeon@kernel.org> |

ntfs: punch all-zero compressed blocks
When a rewritten compression block consists entirely of zeroes, ntfs_write_cb() returns without replacing its existing runlist mapping. The old on-disk contents therefore remain visible after cache eviction. Punch the compression unit so that reads resolve it as a sparse block and release any clusters that held the previous contents.

ntfs: support large pages in compressed writes
ntfs_compress_write() derives its page count by shifting the compression block size and assumes that every compression block begins at a page boundary. This produces a zero page count for small compression blocks on large-page systems and ignores an in-page compression block offset. Map every page covering the compression block, pass the in-page offset to ntfs_write_cb(), and stage uncompressed output in page-aligned pages.

ntfs: file extension before write submission
Prepare non-resident file allocation and initialized-size extension in ->write_iter() before entering the buffered or direct iomap write paths. Previously, the iomap write callback extended initialized_size. When a direct write started beyond initialized_size, ntfs_extend_initialized_size() used iomap_zero_range() to zero the gap through the page cache. This created dirty folios after iomap DIO had invalidated its target cache range. The bsync path then had to synchronously write back the entire zeroed gap to prevent the post-DIO invalidation from encountering a dirty boundary folio. Move allocation and initialized-size preparation ahead of iomap submission. For DIO, kiocb_invalidate_pages() now sees any dirty boundary folio created by iomap_zero_range(), writes it back when necessary, and invalidates it before the direct I/O is issued. This removes the explicit synchronous writeback of the zeroed gap while preserving the required boundary-folio ordering. Keep compressed writes out of the early initialized-size extension so their existing write path can zero uninitialized data before compression. Move compressed-file allocation expansion to write_iter as well, eliminating the now-redundant expansion from ntfs_compress_write().

ntfs: fix kmap_local_page() usage in compress
Several compressed I/O paths discard the address returned by
kmap_local_page() and later access or unmap the page using page_address().
This is invalid for highmem pages, and local mappings must also be unmapped
using the address returned by kmap_local_page().
Map each destination page in ntfs_decompress() only while producing the
current sub-block. Use memcpy_from_page(), memcpy_to_page(), and
memzero_page() for the other page accesses. Remove unnecessary local
mappings from ntfs_write_cb(), where pages are accessed through the vmap()
mapping.

ntfs: Fix min_len for compressed/sparse attributes in ntfs_non_resident_attr_value_is_valid()
Here the attribute validator computes a single min_len = 64 (as the end of initialized_size) for all non-resident attributes regardless of the flags field. This is correct for regular non-resident attributes but for sparse or compressed non-resident attributes the fixed header is 8 bytes longer, it includes a compressed_size field at bytes 64-71, min_len should be 72. Since the validator lets a sparse/compressed attr_record be less than the correct length, caller's accesses to compressed_size (e.g., ntfs_read_locked_inode() or ntfs_attr_update_mapping_pairs()) can extend past the attribute declared boundary. This can cause OOB reads or OOB writes past the MFT record buffer if the attribute is positioned near the end of the MFT record. The compressed_size field is accessed from: - ntfs_read_locked_inode() - ntfs_read_locked_attr_inode() - ntfs_attr_open() - ntfs_attr_update_mapping_pairs() ntfs_attr_make_non_resident() seems to be safe. Fixing this by raising min_len for sparse/compressed attributes in the validator. The OOB reads and the OOB writes require a crafted filesystem image, which is not in the kernel threat model, anyway, fixing memory errors would be nice to keep things secure.

ntfs: rewrite EA stream before updating metadata
Updating an EA removes the old record and appends its replacement.
Build the complete $EA stream in memory and rewrite it from offset zero,
rather than committing a compacted stream followed by a separate append.
generic/642 shows that the append path can leave an invalid record layout
on disk, including when a new EA entry is added.
When removing an EA, write the compacted stream before updating
$EA_INFORMATION and restore the original pair if the metadata update
fails.
When the final EA entry is removed the $EA/$EA_INFORMATION pair is torn
down. If removing $EA_INFORMATION fails after $EA has already been
removed, the original $EA is restored so the two attributes stay
consistent.

soc: Arm platform updates for 7.3
The 32-bit Arm platforms are a bit more interesting this time: I refreshed
an earlier series to mark code as deprecated that does have the tendency
of getting in the way of cleanups and new features but has close to zero
users. Among these are:
- 22 of the remaining 28 legacy board files that predate the current
devicetree based descriptions, using old chips from Intel and Marvell.
The remaining six board files are for TI OMAP1 and Samsung s3c64xx
chips and all still have known users.
- support for Cortex-M3/M4/M7 and ARM1136r0 CPU cores and the 25
machines based on these. These all use devicetree but the CPU
support causes disproportional work. Most of them are just
reference boards, the notable exceptions being the Nokia N800/N810
tablet and the Buglabs BUG platform.
- be8, be32, oabi and iwmmxt userspace binaries, which were mostly
associated with the platforms now scheduled for removal and
are increasingly problematic to support with modern toolchains.
Nothing is actually removed at this point, to ensure that any remaining
users continue to have the 7.3-LTS for a while longer. Patches for
removal are currently being tested.
Other updates include a continued work to convert GPIO number based
interfaces to descriptors, a patch to restore little-endian mode
on the one Arm platform (ixp4xx) that only worked in big-endian mode
recently, and some minor cleanups and bugfixes.

soc: devicetree updates for 7.3
There are two new mystery SoCs with very little public information
about them so far, Qualcomm's Cortex-A78C based "Shikra" and
Altera's Cortex-A720 based Agilex72 SOCFPGA.
We have also gained support for a couple of SoCs from the
2023/2024 timeframe that have been in the making for a while:
- The Apple platform gains support for M3 Pro, Max and Ultra SoC,
following the basic M3 support from 7.2.
- Samsung Exynos 1580 is a high-end mobile phone SoC from 2024
- Canaan K230 is a RISC-V based 64-bit AI SoC, based on the
earlier K210 chip
- Sophgo SG2000 is a mixed Arm/RISC-V chip that was already
supported using the Arm core but is now also added for RISC-V
along with several other variants of the cv18xx series
In terms of newly added machines we have reference platforms
for all the chips above, plus
- only four 32-bit Arm boards: two older phones and two
older industrial/embedded boards; using Allwinner, Qualcomm and
Rockchip SoCs
- Three laptops und three phones using Qualcomm SoCs
- Ten 64-bit Rockchips based single-board computers, along with one
NAS box and a game console.
- Seven industrial/embedded boards and modules using NXP i.MX8/9 SoCs.
- A Lenovo desktop box based on NVIDIA Jetson Xavier NX
- A few more single-board computers based on Allwinnner A133,
Spacemit K1 and TI AM62.
As usual, there is a constant stream of minor cleanups and fixes
towards addressing the 'dt-check-style --mode strict' warnings,
and everyone is expected to address those warnings for new
submissions now.

These changes are useful independently and enable previously missing debugging facilities on Alpha.

Pull x86 mm updates from Dave Hansen:
"There are two things in here of note. First, there are fixes to reduce
the time that the TLB flushing code sits around with interrupts
disabled. It should be well tested, but it's certainly something to
keep an eye on.
Second is a little back-and-forth in the interactions between the
set_memory*() locking and DEBUG_PAGEALLOC. There was a slightly
painful re-discovery of why DEBUG_PAGEALLOC has special locking rules,
but the code did end up better for it.
Summary:
- Fix pkey_alloc() return value when pkeys are not supported
- Allow preemption during IPI completion waiting to improve wakeup
latency
- Convert more x86 page table code to ptdescs
- Fixes and cleanups for set_memory*() locking, mostly around large
pages"

Timers and timekeeping core updates:
- Fix a subtly inconsistency in the timekeeping code, which fails to
account for the monotonicity adjustment in ntp_error. For small changes
of the clocksource multiplicator (+/-1) which are typically used by the
NTP PLL this is hardly to observe. But for larger adjustments,
e.g. caused by a direct frequency setting through adjtimex() the
one-time uncompensated offset is significant.
Cure this by adjusting ntp_error with the resulting offset so that the
discrepancy is smoothed away over time
- Make tick length calculations correct in NTP. The timekeeping core
takes the quantisation of the clocksource into account when calculating
the tick length to compensate for the deviation of the nominal
NTP_INTERVAL_LENGTH. While timekeeping gets this right, NTP is not
aware of that, which means it operates on the nominal value and not on
the actual value which is determined by the clock source frequency. The
rounding of a coarse clocksource like the ACPI PM timer results in a
+127 PPM deviation.
Cure this by exposing the deviation to the NTP code so that it can
operate on the same data as the timekeeping core. This is purely kernel
internal. User space still sees the nominal tick lenght via adjtimex().
- The accuracy of the NTP adjustments is fairly approximate as the code
assumes that the invocations are precisely in NTP interval frequency
ticks and the final adjustment can over and under-run.
Cure this by adjusting ntp_error by the intended skew on each tick to
achieve the desired rate.
- Handle the two competing skews of time offset and time adjustment
correctly by calculating the conflict portion between the skews and
adjusting both accordingly.
- A set of updates and improvements for the selftests
- The usual small fixes and improvements all over the place

Treewide timer related cleanups:
- Remove the leftover CLOCK_TICK_RATE which has been scheduled for
removal more than a decade ago along with some now empty asm/timex.h
files.
- Consolidate delay timer calibration
The construct of having a define in a header requires that
architectures provided asm/timex.h for no reason. Also the function
name for reading the delay timer is confusing at best.
Use a config switch to enable that functionality and rename the
function to delay_read_timer() to make the purpose clear.
This removes some more now empty asm/timex.h files as well.

Pull treewide timer related cleanups from Thomas Gleixner:
- Remove the leftover CLOCK_TICK_RATE which has been scheduled for
removal more than a decade ago along with some now empty asm/timex.h
files.
- Consolidate delay timer calibration
The construct of having a define in a header requires that
architectures provided asm/timex.h for no reason. Also the function
name for reading the delay timer is confusing at best.
Use a config switch to enable that functionality and rename the
function to delay_read_timer() to make the purpose clear.
This removes some more now empty asm/timex.h files as well.

SMP core updates:
- Reduce the preemption disabled sections in smp_call_function*().
The various smp call functions keep preemption disabled accross the
full operation which includes the wait for completion. Especially the
latter can take some time when one of the target CPUs is not
immediately responding to the IPI, which can result in large latency
spikes.
To improve this provide a per task CPU mask to track the CPUs to wait
for. That makes the information required for the wait task local and
therefore allows to reenable preemption before the wait. While this
comes with moderate extra memory cost this reduces SMP function call
induced latency measured in a fleet for high priority tasks from ~17ms
to ~1.5ms (~90%).
- Reduce the overhead of the CSD debug code by replacing the heavy memory
barriers with smp_store_release()/acquire().
- Remove obsolute unused hotplug states

- Remove the unused IMGPDC driver, which got orphaned when the metag
architecture was removed long ago.
- Update the Qualcom PDC interrupt chip driver to support differnent
versions of the IP block, to properly differentiable between direct and
GPIO based interrupts and to utilize pass through mode to the
underlying GIC interrupt.
- Remove redundant dev_err() and dev_err_probe() invocations in various
drivers as that error logging has been moved to devm_request_*_irq().
- Support dynamic MSI-X allocations in the GIC-V3-ITS MSI parent domain
driver. That's important for VFIO pass through devices to avoid
reinitialization of the MSI-X space when extending the vector
range. Such a reinitialization can result is lost interrupts and stale
devices.

Generic entry code updates:
- Make syscall user dispatching configurable
Not all architectures can makes use of syscall user dispatching. Allow
them to disable the feature completely.
- Consolidate stack randomization for the generic entry code and the
architectures using it.
Stack randomization on syscall entry was sprinkled throughout the
architecture specific low level entry code and in some cases at the
wrong points, e.g. before establishing state, which violates the
non-instrumentable constraints of that code.
Clean this up by integrating stack randomization into the generic entry
code helpers so that it is invoked at the earliest possible point right
after establishing state and converting all generic entry code using
architecture over.
- Clean up the syscall number handling in the generic entry code. It
works correctly for architectures which have a separate return value
storage in pt_regs, but fails to distinguish the case where user space
handed in -1 as syscall number from the case where the entry code
rejects it by returning -1 to the callers. Aside of that the return
value functionality of those interfaces is not really intuitive.
Fix this by separating the decision to reject a syscall (user dispatch,
ptrace, seccomp ...) from the potential modification of the syscall
number through these mechanisms.
This solves most of the problems for architectures which do not have a
separate return value storage in pt_regs except for the case where a
tracepoint has a BPF script or a probe attached which overwrite both
the syscall number and the return value. But that's a problem which
cannot be solved in the generic code, that only can be addressed by
separating the storage model in the affected architectures.

dispatch, ptrace, seccomp ...) from the potential modification of the
syscall number through these mechanisms.
This solves most of the problems for architectures which do not have
a separate return value storage in pt_regs except for the case where
a tracepoint has a BPF script or a probe attached which overwrite
both the syscall number and the return value. But that's a problem
which cannot be solved in the generic code, that only can be
addressed by separating the storage model in the affected
architectures.
