[PATCH v4 1/2] usb: dwc3: gadget: Fix TRB reclaim logic for short transfers and ZLPs

by Johannes Schneider

Commit 61440628a4ff ("usb: dwc3: gadget: Cleanup SG handling") updated the TRB reclaim path to use the TRB CHN (Chain) bit to determine whether a TRB was part of a chain. However, this inadvertently changed the behavior of reclaiming the final TRB in some scatter-gather or short transfer cases. In particular, if the final TRB did not have the CHN bit set, the cleanup path could incorrectly skip clearing the HWO (Hardware Own) bit, leaving stale TRBs in the ring. This resulted in broken data transfer completions in userspace, notably for MTP over FunctionFS. Fix this by unconditionally clearing the HWO bit during TRB reclaim, regardless of the CHN bit state. This restores correct behavior especially for transfers that require ZLPs or end on non-CHN TRBs.

[PATCH v4] iio: common: st_sensors: Fix use of uninitialize device structs

by Maud Spierings via B4 Relay

From: Maud Spierings <maudspierings(a)gocontroll.com> Throughout the various probe functions &indio_dev->dev is used before it is initialized. This caused a kernel panic in st_sensors_power_enable() when the call to devm_regulator_bulk_get_enable() fails and then calls dev_err_probe() with the uninitialized device. This seems to only cause a panic with dev_err_probe(), dev_err(), dev_warn() and dev_info() don't seem to cause a panic, but are fixed as well. The issue is reported and traced here: [1] Link: https://lore.kernel.org/all/AM7P189MB100986A83D2F28AF3FFAF976E39EA@AM7P189M… [1] Cc: stable(a)vger.kernel.org Signed-off-by: Maud Spierings <maudspierings(a)gocontroll.com> --- When I search for general &indio_dev->dev usage, I see quite a lot more hits, but I am not sure if there are issues with those too. This issue has existed for a long time it seems and therefore it is nearly impossible to find a proper fixes tag. I would love to see it at least backported to 6.12 as that is where I encountered it, and I believe the patch should apply without conflicts. --- Changes in v4: - Put the link to the original issue in a proper link tag - Remove stray newline - Link to v3: https://lore.kernel.org/r/20250526-st_iio_fix-v3-1-039fec38707c@gocontroll.… Changes in v3: - Added the stable cc to the commit message - Move the link to the original issue to the commit message - Fix function notation in the commit message - Move some more of the dev_*() calls to one line - Link to v2: https://lore.kernel.org/r/20250522-st_iio_fix-v2-1-07a32655a996@gocontroll.… Changes in v2: - Added SoB in commit message - Link to v1: https://lore.kernel.org/r/20250522-st_iio_fix-v1-1-d689b35f1612@gocontroll.… --- drivers/iio/accel/st_accel_core.c | 10 +++--- drivers/iio/common/st_sensors/st_sensors_core.c | 36 ++++++++++------------ drivers/iio/common/st_sensors/st_sensors_trigger.c | 20 ++++++------ 3 files changed, 31 insertions(+), 35 deletions(-) diff --git a/drivers/iio/accel/st_accel_core.c b/drivers/iio/accel/st_accel_core.c index 99cb661fabb2d9cc1943fa8d0a6f3becb71126e6..a7961c610ed203d039bbf298c8883031a578fb0b 100644 --- a/drivers/iio/accel/st_accel_core.c +++ b/drivers/iio/accel/st_accel_core.c @@ -1353,6 +1353,7 @@ static int apply_acpi_orientation(struct iio_dev *indio_dev) union acpi_object *ont;

[PATCH v 5] usb: dwc2: gadget: Fix enter to hibernation for UTMI+ PHY

by Minas Harutyunyan

For UTMI+ PHY, according to programming guide, first should be set PMUACTV bit then STOPPCLK bit. Otherwise, when the device issues Remote Wakeup, then host notices disconnect instead. For ULPI PHY, above mentioned bits must be set in reversed order: STOPPCLK then PMUACTV.

[PATCH 6.12.y 0/2] crypto: rng - FIPS 140-3 compliance for random number generation

by Jay Wang

This patch series implements FIPS 140-3 compliance requirements for random number generation in the Linux kernel 6.12. The changes ensure that when the kernel is operating in FIPS mode, FIPS-compliant random number generators are used instead of the default /dev/random implementation. IMPORTANT: These two patches must be applied together as a series. Applying only the first patch without the second will cause a deadlock during boot in FIPS-enabled environments. The second patch fixes a critical timing issue introduced by the first patch where the crypto RNG attempts to override the drivers/char/random interface before the default RNG becomes available. The series consists of two patches: 1. Initial implementation to override drivers/char/random in FIPS mode 2. Refinement to ensure override only occurs after FIPS-mode RNGs are available These 2 patches are required for FIPS 140-3 certification and compliance in government and enterprise environments.

A common failure is due to new MCA bank types that are not recognized and don't have a short name set. The MCA thresholding feature is optional and should not break the common MCE sysfs interface. Also, new MCA bank types are occasionally introduced, and updates will be needed to recognize them. But likewise, this should not break the common sysfs interface. Keep the MCE sysfs interface regardless of the status of the thresholding sysfs interface.

This tells the kernel to *not* start the MCE timer on a CPU. If the user did not disable CMCI, then storms can occur. When these happen, the MCE timer will be started with a fixed interval. After the storm subsides, the timer's next interval is set to check_interval. This disregards the user's input through "ignore_ce" and "check_interval". Furthermore, if "check_interval=0", then the new timer will run faster than expected. Create a new helper to check these conditions and use it when a CMCI storm ends.

[PATCH v2 1/1] mm/rmap: fix potential out-of-bounds page table access during batched unmap

by Lance Yang

From: Lance Yang <lance.yang(a)linux.dev> As pointed out by David[1], the batched unmap logic in try_to_unmap_one() can read past the end of a PTE table if a large folio is mapped starting at the last entry of that table. It would be quite rare in practice, as MADV_FREE typically splits the large folio ;) So let's fix the potential out-of-bounds read by refactoring the logic into a new helper, folio_unmap_pte_batch(). The new helper now correctly calculates the safe number of pages to scan by limiting the operation to the boundaries of the current VMA and the PTE table. In addition, the "all-or-nothing" batching restriction is removed to support partial batches. The reference counting is also cleaned up to use folio_put_refs().

The current mTHP swapin path have some problems. It may potentially hang, may cause redundant faults due to false positive swap cache lookup, and it will involve at least 4 Xarray tree walks (get order, get order again, confirm swap, insert folio). And for !CONFIG_TRANSPARENT_HUGEPAGE builds, it will performs some mTHP related checks. This series fixes all of the mentioned issues, and the code should be more robust and prepared for the swap table series. Now tree walks is reduced to twice (get order & confirm, insert folio) and added more sanity checks and comments. !CONFIG_TRANSPARENT_HUGEPAGE build overhead is also minimized, and comes with a sanity check now. The performance is slightly better after this series, sequential swap in of 24G data from ZRAM, using transparent_hugepage_tmpfs=always (24 samples each): Before: 11.17, Standard Deviation: 0.02 After patch 1: 10.89, Standard Deviation: 0.05 After patch 2: 10.84, Standard Deviation: 0.03 After patch 3: 10.91, Standard Deviation: 0.03 After patch 4: 10.86, Standard Deviation: 0.03 After patch 5: 10.07, Standard Deviation: 0.04 After patch 7: 10.09, Standard Deviation: 0.03 Each patch improves the performance by a little, which is about ~10% faster in total. Build kernel test showed very slightly improvement, testing with make -j24 with defconfig in a 256M memcg also using ZRAM as swap, and transparent_hugepage_tmpfs=always (6 test runs): Before: system time avg: 3911.80s After: system time avg: 3863.76s This patch (of 7): The current swap-in code assumes that, when a swap entry in shmem mapping is order 0, its cached folios (if present) must be order 0 too, which turns out not always correct. The problem is shmem_split_large_entry is called before verifying the folio will eventually be swapped in, one possible race is: CPU1 CPU2 shmem_swapin_folio /* swap in of order > 0 swap entry S1 */ folio = swap_cache_get_folio /* folio = NULL */ order = xa_get_order /* order > 0 */ folio = shmem_swap_alloc_folio /* mTHP alloc failure, folio = NULL */ <... Interrupted ...> shmem_swapin_folio /* S1 is swapped in */ shmem_writeout /* S1 is swapped out, folio cached */ shmem_split_large_entry(..., S1) /* S1 is split, but the folio covering it has order > 0 now */ Now any following swapin of S1 will hang: `xa_get_order` returns 0, and folio lookup will return a folio with order > 0. The `xa_get_order(&mapping->i_pages, index) != folio_order(folio)` will always return false causing swap-in to return -EEXIST. And this looks fragile. So fix this up by allowing seeing a larger folio in swap cache, and check the whole shmem mapping range covered by the swapin have the right swap value upon inserting the folio. And drop the redundant tree walks before the insertion. This will actually improve performance, as it avoids two redundant Xarray tree walks in the hot path, and the only side effect is that in the failure path, shmem may redundantly reallocate a few folios causing temporary slight memory pressure. And worth noting, it may seems the order and value check before inserting might help reducing the lock contention, which is not true. The swap cache layer ensures raced swapin will either see a swap cache folio or failed to do a swapin (we have SWAP_HAS_CACHE bit even if swap cache is bypassed), so holding the folio lock and checking the folio flag is already good enough for avoiding the lock contention. The chance that a folio passes the swap entry value check but the shmem mapping slot has changed should be very low.

It would be quite rare in practice, as MADV_FREE typically splits the large folio ;) So let's fix the potential out-of-bounds read by refactoring the logic into a new helper, folio_unmap_pte_batch(). The new helper now correctly calculates the safe number of pages to scan by limiting the operation to the boundaries of the current VMA and the PTE table. In addition, the "all-or-nothing" batching restriction is removed to support partial batches. The reference counting is also cleaned up to use folio_put_refs().

[PATCH v1 3/4] mpi3mr: Serialize admin queue BAR writes on 32-bit systems

by Ranjan Kumar

On 32-bit systems, 64-bit BAR writes to admin queue registers are performed as two 32-bit writes. Without locking, this can cause partial writes when accessed concurrently. Updated per-queue spinlocks is used to serialize these writes and prevent race conditions.

The "is_waiting" flag was updated after calling complete(), which could lead to a race where the waiting thread wakes up before the flag is cleared, may cause a missed wakeup or stale state check.

[PATCH v3] Bluetooth: HCI: Set extended advertising data synchronously

by Christian Eggers

Currently, for controllers with extended advertising, the advertising data is set in the asynchronous response handler for extended adverstising params.

[PATCH 1/4] usb: xhci: quirk for data loss in ISOC transfers

by Mathias Nyman

From: Raju Rangoju <Raju.Rangoju(a)amd.com> During the High-Speed Isochronous Audio transfers, xHCI controller on certain AMD platforms experiences momentary data loss. This results in Missed Service Errors (MSE) being generated by the xHCI. The root cause of the MSE is attributed to the ISOC OUT endpoint being omitted from scheduling. This can happen when an IN endpoint with a 64ms service interval either is pre-scheduled prior to the ISOC OUT endpoint or the interval of the ISOC OUT endpoint is shorter than that of the IN endpoint. Consequently, the OUT service is neglected when an IN endpoint with a service interval exceeding 32ms is scheduled concurrently (every 64ms in this scenario). This issue is particularly seen on certain older AMD platforms. To mitigate this problem, it is recommended to adjust the service interval of the IN endpoint to not exceed 32ms (interval 8). This adjustment ensures that the OUT endpoint will not be bypassed, even if a smaller interval value is utilized.

[PATCH v3 0/3] Samsung Exynos 7870 DECON driver support

by Kaustabh Chakraborty

This patch series aims at adding support for Exynos7870's DECON in the Exynos7 DECON driver. It introduces a driver data struct so that support for DECON on other SoCs can be added to it in the future. It also fixes a few bugs in the driver, such as functions receiving bad pointers. Tested on Samsung Galaxy J7 Prime (samsung-on7xelte), Samsung Galaxy A2 Core (samsung-a2corelte), and Samsung Galaxy J6 (samsung-j6lte). Signed-off-by: Kaustabh Chakraborty <kauschluss(a)disroot.org> --- Changes in v3: - Add a new commit documenting iommus and ports dt properties. - Link to v2: https://lore.kernel.org/r/20250612-exynosdrm-decon-v2-0-d6c1d21c8057@disroo… Changes in v2: - Add a new commit to prevent an occasional panic under circumstances. - Rewrite and redo [v1 2/6] to be a more sensible commit. - Link to v1: https://lore.kernel.org/r/20240919-exynosdrm-decon-v1-0-6c5861c1cb04@disroo… --- Kaustabh Chakraborty (3): dt-bindings: display: samsung,exynos7-decon: add properties for iommus and ports drm/exynos: exynos7_drm_decon: fix call of decon_commit() drm/exynos: exynos7_drm_decon: add vblank check in IRQ handling .../bindings/display/samsung/samsung,exynos7-decon.yaml | 8 ++++++++ drivers/gpu/drm/exynos/exynos7_drm_decon.c | 8 ++++++-- 2 files changed, 14 insertions(+), 2 deletions(-) --- base-commit: 1b152eeca84a02bdb648f16b82ef3394007a9dcf change-id: 20240917-exynosdrm-decon-4c228dd1d2bf Best regards, -- Kaustabh Chakraborty <kauschluss(a)disroot.org>

[PATCH] drm/gem: Acquire references on GEM handles for framebuffers

by Thomas Zimmermann

A GEM handle can be released while the GEM buffer object is attached to a DRM framebuffer. This leads to the release of the dma-buf backing the buffer object, if any. [1] Trying to use the framebuffer in further mode-setting operations leads to a segmentation fault. Most easily happens with driver that use shadow planes for vmap-ing the dma-buf during a page flip. An example is shown below.
