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: Remove references to page->__folio_index
Pages don't have indexes, folios have indexes. Correct this in
ntfs_read_compressed_block() and also remove a use of page->mapping
while I'm in here. Also convert the calls to unlock_page() and
flush_dcache_page().

ntfs: Use zero_user_segment() in handle_bounds_compressed_page()
This fixes handle_bounds_compressed_page() on highmem memory
as page_address() does not work on memory which has been kmap_local(),
only on kmap() memory.

ntfs: Remove use of __folio_index in handle_bounds_compressed_page()
Nobody is supposed to use page->__folio_index. Use page_offset()
instead, and simplify by working exclusively in loff_t instead of mixing
up loff_t and pgoff_t.

ntfs: Inline zero_partial_compressed_page()
zero_partial_compressed_page() has one caller and the next commit
will make changes to it that make it inelegant to split across two
functions.

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.

ntfs: remove empty EA attribute pair
Removing the final xattr leaves an empty $EA stream. An empty $EA
attribute paired with $EA_INFORMATION is not a valid EA chain and
ntfsck reports it as corrupt.
Remove both attributes when the final EA entry is deleted.
Fixes:

ntfs: validate final EA attribute size
A replacement first removes the existing EA record, then adds the
replacement. Check the size of that final $EA stream before mutating
the current stream.
This avoids committing the shortened $EA stream or $EA_INFORMATION before
discovering that the replacement exceeds the AttrDef size limit.

IIO new device support, features, cleanup for 7.3
Includes a merge of 7.2-rc2 to pick up the changes around mod_devicetable.h and reduce resulting conflicts around includes. New device support ------------------ adi,ad3530R - Add support for the AD3532R and AD3532 16 channel DACs. adi,ad4080 - Add support for the AD4883 ADC. adi,ad5686 - Add support for AD5313R, AD5317R, AD5674, AD5687R, AD5689, AD5689R DACs over SPI - Add support for AD5316R, AD5674, AD5697R and AD5696 DACs over I2C - Significant driver refactoring prior to these additions, partly to reduce bus traffic and to add triggered buffer and gain control support. An earlier set added support for missing supplies, reset and LDAC GPIO. adi,adf41513 - New driver to support this PLL frequency synthesizer that runs up to 26.5 GHz. - Included infrastructure to handle higher precision attributes with extensive tests adi,ltc2378-20 - New driver supporting LTC2338, LTC2364, LTC2367, LTC2368, LT2369, LTC2370 LTC2376, LTC2377, LTC2378, LTC2379 and LTC23980 ADCs with both high speed capture via appropriate backend and conventional triggered buffer SPI capture. invensense,icm42607 - New driver for this IMU. mediateck,mt6323 - New driver for this PMIC ADC. microchip,mcp47a1 - New driver for this I2C 6 bit DAC. nxp,mcf54415-dac - New driver for this DAC found in NXP SoCs. qst,qmc5884l - New driver for this 3 axis magnetometer. Included dt vendor entry for qst. qst,qmc6308 - New driver for this 3 axis magnetometer. sensiron,slf3s - New driver for this liquid flow sensor. Includes adding IIO_VOLUMEFLOW channel type. st,vl53l1x - Refactors to improve readability. ti,ads112c14 - New driver supporting the ADS112C14 and ADS122C14 ADCs. These bring some new ABI for input chopping, particular useful for resistive sensors like thermocouples or Wheatstone bridges. - Support CRC8 detection of corruption on the bus. - Support buffered reads. ti,tmp117 - (trivial) Add support for the tmp119 temperature sensor. xilinx,versal-sysmon - New ADC driver for this block found on various FPGAs including various bus interfaces, threshold and oversampling support. dt binding updates ------------------ new shared bindings - excitation-channels and excitation-current-nanoamp allow per channel specification of currents used for resistive sensor measurement. - reference-sources property to allow selection of a per channel reference. rockchip,saradc - Add RV1106 which is compatible with the RV3588. Features -------- buffer-dmaengine - Allow cyclic buffers, useful for repeating sequence generation with DACs. devantech,dmard09 - Implement read back of channel scale - previously interface always returned an error. hid,sensors-als - Enable separate channel scaling for hardware that supports it. invensense,timestamp library - Various precision improvements. invensense,icm42600 - Add support for hwfifo watermark interfaces. taos,tcs3472 - Support wait time and sampling frequency control. Cleanups, minor fixes --------------------- Minor cleanups not mentioned at all in this summary such as white space fixes or typos. Affecting various drivers - Cleanup of conditionals that had no affect. - Drop some runtime pm local wrappers as now runtime_pm does the mark_last_busy part inside the put, these provide no useful code deduplication or readability advantages over directly calling the runtime_pm functions. - Return 0 from write_raw() on success. - Use of dev_err_probe() to simplify code and sometimes provide useful info for deferred probe debugging. - Drop some redundant error prints where the called function already provides information on errors. - Make some read only arrays in functions static. - Fix up missing handling of regcache_sync() errors. - Drop some false kernel-doc markings. - Add missing MODULE_DEVICE_TABLE for some of_match_id tables. - Use local variables for things like the struct device to shorten and improve readability of code. - Drop some unused structure elements. - Reorder dds.h macro parameters to be inline with others. - Header reorders and IWYU. Often part of a more significant series. - Remove abstractions designed to allow a driver to support multiple device types, when they have been around a long time and only the original part showed up. - Initialize spi_device_id arrays using member names following dropping of driver data from drivers that didn't actually use it. - Catch up with i2c_device_id tables added since previous effort to use named initializers for all those. - Use kernel types in a few places instead of standard C ones or bare unsigned. Misc - Update Xilinx AMS maintainer. - Update email address for Maxwell Doose. - Update email address for Siratul Islam. - Update email address for Tomasz Duszynski and re-add Tomasz to various maintainer entries. Docs - Encourage use of differential channel naming even when there is no flexibility in input to differential pair mapping. Intended to provide a strong signal to userspace that a channel is differential. adi,ad_sigma_delta - Allow COMPILE_TEST without any users. adi,ad2s1201 - Refactor trigger handler to avoid mix of guard() and goto. adi,ad5686 - Avoid potential NULL dereference is user forces a driver bind. adi,ad5696 - Add a couple of missing entries to the of_match_id table and update binding to match. atmel,ad91_adc - Use const char * for DT string property allowing a cast to be dropped. avia,hx711 - Various refactors and cleanup to enable support of additional parts (to come) - Add missing supply and gpio dt-bindings. bosch,bmc150 - Harden against device reporting too large a FIFO sample count. - Use FIELD_PREP() / FIELD_GET() to improve readability. freescale,fxls8962af - Harden against device reporting too large a FIFO sample count. hid-sensors-* - Reorder probe to not expose userspace interfaces until the rest of the setup is done to avoid potentially dropping data. honeywell,abp2030pa - Drop an unreachable return. invensens,icm45600 - Harden against bad value of FIFO sample count from device. - Use i2c_match_data if firmware table sourced match data isn't available. nxp,mpl1115 - Ensure runtime_pm is balanced on error in probe. rohm,bm1390 - Make the driver slightly more likely to recover from transient errors. sensiron,sgp30 - Handle thread creation errors. st,lsm6dsx - Update the enable mask when doing sensor fusion to avoid incorrect fifo data handling. st,stm32-dfsdm - Treat dt flags as booleans. ti,ads1015 - Switch to devm helpers which simplified code and closed a resource leak. ti,opt3001 - Split complicated opt3001_get_processed() logic into irq an no irq helper functions. - Use devm to simplify code. - Use guard() to simplify code. - Reorder probe so final call exposes userspace interfaces. - Various other more minor cleanup taos,tsl2772 - Fix calibscale readback to check right channel type. taos,tsl2583 - Use sysfs_emit() and sysfs_emit_at() to replace open coded equivalents. -----BEGIN PGP SIGNATURE----- iQJFBAABCgAvFiEEbilms4eEBlKRJoGxVIU0mcT0FogFAmp1Pm8RHGppYzIzQGtl cm5lbC5vcmcACgkQVIU0mcT0FoioNRAAi338gJ/xvG3rZlPr1RrTEgmsWaMqxxpr FWxFApdjAGvINn6SGwcWWkdfmB+OYg8sbhLLGkOx07e9R/GbS0y3j2kODvZHodZz k3wYXEy12HwuMgQRQWR+rNIke6bJdJFI10saJTfIRr3if7GkVvBTqd9exfoD2vGa Xzj12YN6ZcRiv8eWgju4yqQuVomMkRigd2mDHwvN4H9/ZylBRMgGIHhteWoPjx3y hs6lLeqc8lfocz1Azslb0ZEDPJ4+zPCO9eCBZ+1ZMwrzKUeqCfMYDQdE9TVUswpG aHlr5E+R2PlpLn4Ijk0faFJUZYFaOFIn3II3ZZfzzgFop2C0cVORYuIf7bgDRsaD zrLj2ybzSr/7+aAK2ry3hoVrxh9mkbv6G0Lf7bvFhQaXltJJBVQi98pU13p2AoFj BT8+pHOwgKUsF+LyxNqch6LyLDEzNw0P3Fl7SmrH/k2RVfj/L4+8PMOAijBTLpCC 3J4k17laTYWJZ8sFpyBEXYyhgp6SZqr2UIIcizrc1nIUK+mJI2/XBVbtsBY/6jW8 7RM07TNqkm+ZhsV58YiMfKdDuqPiQpCp5TYjVcxjjmOK4aE5bFSbyzi5SvAcG6oG C2l9k5vgZEpti6ZkFBj4qNUK0cVXinDWqHhlAXF7wjKCj69yEFLCtl+de//A0I+v 3FBEkBCsq+M= =4ayG -----END PGP SIGNATURE----- Merge tag 'iio-for-7.3a' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Jonathan writes: IIO new device support, features, cleanup for 7.3 Includes a merge of 7.2-rc2 to pick up the changes around mod_devicetable.h and reduce resulting conflicts around includes.

Features -------- buffer-dmaengine - Allow cyclic buffers, useful for repeating sequence generation with DACs. devantech,dmard09 - Implement read back of channel scale - previously interface always returned an error. hid,sensors-als - Enable separate channel scaling for hardware that supports it. invensense,timestamp library - Various precision improvements. invensense,icm42600 - Add support for hwfifo watermark interfaces. taos,tcs3472 - Support wait time and sampling frequency control. Cleanups, minor fixes --------------------- Minor cleanups not mentioned at all in this summary such as white space fixes or typos. Affecting various drivers - Cleanup of conditionals that had no affect. - Drop some runtime pm local wrappers as now runtime_pm does the mark_last_busy part inside the put, these provide no useful code deduplication or readability advantages over directly calling the runtime_pm functions. - Return 0 from write_raw() on success. - Use of dev_err_probe() to simplify code and sometimes provide useful info for deferred probe debugging. - Drop some redundant error prints where the called function already provides information on errors. - Make some read only arrays in functions static. - Fix up missing handling of regcache_sync() errors. - Drop some false kernel-doc markings. - Add missing MODULE_DEVICE_TABLE for some of_match_id tables. - Use local variables for things like the struct device to shorten and improve readability of code. - Drop some unused structure elements. - Reorder dds.h macro parameters to be inline with others. - Header reorders and IWYU. Often part of a more significant series. - Remove abstractions designed to allow a driver to support multiple device types, when they have been around a long time and only the original part showed up. - Initialize spi_device_id arrays using member names following dropping of driver data from drivers that didn't actually use it. - Catch up with i2c_device_id tables added since previous effort to use named initializers for all those. - Use kernel types in a few places instead of standard C ones or bare unsigned. Misc - Update Xilinx AMS maintainer. - Update email address for Maxwell Doose. - Update email address for Siratul Islam. - Update email address for Tomasz Duszynski and re-add Tomasz to various maintainer entries. Docs - Encourage use of differential channel naming even when there is no flexibility in input to differential pair mapping. Intended to provide a strong signal to userspace that a channel is differential. adi,ad_sigma_delta - Allow COMPILE_TEST without any users. adi,ad2s1201 - Refactor trigger handler to avoid mix of guard() and goto. adi,ad5686 - Avoid potential NULL dereference is user forces a driver bind. adi,ad5696 - Add a couple of missing entries to the of_match_id table and update binding to match. atmel,ad91_adc - Use const char * for DT string property allowing a cast to be dropped. avia,hx711 - Various refactors and cleanup to enable support of additional parts (to come) - Add missing supply and gpio dt-bindings. bosch,bmc150 - Harden against device reporting too large a FIFO sample count. - Use FIELD_PREP() / FIELD_GET() to improve readability. freescale,fxls8962af - Harden against device reporting too large a FIFO sample count. hid-sensors-* - Reorder probe to not expose userspace interfaces until the rest of the setup is done to avoid potentially dropping data. honeywell,abp2030pa - Drop an unreachable return. invensens,icm45600 - Harden against bad value of FIFO sample count from device. - Use i2c_match_data if firmware table sourced match data isn't available. nxp,mpl1115 - Ensure runtime_pm is balanced on error in probe. rohm,bm1390 - Make the driver slightly more likely to recover from transient errors. sensiron,sgp30 - Handle thread creation errors. st,lsm6dsx - Update the enable mask when doing sensor fusion to avoid incorrect fifo data handling. st,stm32-dfsdm - Treat dt flags as booleans. ti,ads1015 - Switch to devm helpers which simplified code and closed a resource leak. ti,opt3001 - Split complicated opt3001_get_processed() logic into irq an no irq helper functions. - Use devm to simplify code. - Use guard() to simplify code. - Reorder probe so final call exposes userspace interfaces. - Various other more minor cleanup taos,tsl2772 - Fix calibscale readback to check right channel type. taos,tsl2583 - Use sysfs_emit() and sysfs_emit_at() to replace open coded equivalents. * tag 'iio-for-7.3a' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (232 commits) iio: dac: mcp47a1: add support for new device dt-bindings: iio: dac: add support for mcp47a1 iio: Update email for Maxwell Doose iio: imu: st_lsm6dsx: Update enable mask when using sensor fusion iio: light: cm32181: return zero after writing calibscale iio: flow: add Sensirion SLF3S liquid flow sensor driver iio: core: add IIO_VAL_DECIMAL64_FEMTO format type dt-bindings: iio: flow: add Sensirion SLF3S liquid flow sensor iio: types: add IIO_VOLUMEFLOW channel type iio: ABI: Encourage differential voltage ABI usage iio: adc: ltc2378: Add support for LTC2338-18 iio: adc: ltc2378: Enable triggered buffer data capture iio: adc: ltc2378: Enable high-speed data capture iio: adc: ltc2378: Add support for LTC2378-20 and similar ADCs dt-bindings: iio: adc: Add ltc2378 iio: magnetometer: ak8974: remove conditional return with no effect iio: light: tsl2583: remove conditional return with no effect iio: adc: rcar-gyroadc: remove rcar_gyroadc_set_power() helper iio: light: vcnl4000: remove vcnl4000_set_pm_runtime_state() helper iio: light: vcnl4035: remove vcnl4035_set_pm_runtime_state() helper ... |

i3c: dw: reduce do_daa time if there's no client
dw_i3c_master_daa() derives the number of newly assigned dynamic addresses from cmd->rx_len, the ISR sets it to the number of address slots ENTDAA left unassigned. It starts out as zero, which already means "every address was assigned", so a timed out transfer leaves that value in place and it gets used as a result. If there's no client connected, the addr assign cmd times out, then the driver calls i3c_master_add_i3c_dev_locked() to add devices that are not there, each costing about 1s, thus adds non necessary boot time up to (maxdev * 1)s. Start from maxdevs instead: no address is assigned before ENTDAA runs, and the existing rx_count >= maxdevs check then reports an empty bus.

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: drivers for 7.3
The SoC driver changes once more consist of many small fixes and
cleanups, that are to a large part the result of automated testing. On
platform specific drivers, this includes SoC specific code for xilinx,
freescale/nxp, qualcomm, TI, aspeed, omap, tegra, samsung, rockchip,
renesas, ixp4xx. In firmware drivers, we see a similar picture for
SCMI and qcomtee.
Aside from these, we see actual new hardware support in a few
areas:
- The Apple platform gets a new driver for low power states
- Updates to Qualcomm platform drivers add several new
hardware specific features and additional SoCs.
- Amlogic SoC support for A1 and T7 is added
- The Mediatek MMSYS driver is refactored as a cleanup.

Pull SoC driver updates from Arnd Bergmann:
"The SoC driver changes once more consist of many small fixes and
cleanups, that are to a large part the result of automated testing.
On platform specific drivers, this includes SoC specific code for
xilinx, freescale/nxp, qualcomm, TI, aspeed, omap, tegra, samsung,
rockchip, renesas, ixp4xx. In firmware drivers, we see a similar
picture for SCMI and qcomtee.
Aside from these, we see actual new hardware support in a few areas:
- The Apple platform gets a new driver for low power states
- Updates to Qualcomm platform drivers add several new hardware
specific features and additional SoCs.
- Amlogic SoC support for A1 and T7 is added
- The Mediatek MMSYS driver is refactored as a cleanup"

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

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

Clocksource/event driver updates:
- Remove redundant dev_err() and dev_err_probe() invocations in various
drivers.
- Handle SWAP_IO_SPACE correctly in the rtl-otto driver
- Make the Samsumg PWM timer driver PREEMPT_RT compatible
- Ensure that the SUN4I timer is programmed with a delta larger than zero
as a zero delta causes the the timer to be disabled.
- The usual fixes and improvements all over the place
