git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux Pull hardening updates from Kees Cook: - string: Add missing kernel-doc return descriptions (Kriish Sharma) - Update some mis-typed allocations These correct some accidentally wrong types used in allocations (that didn't affect the resulting size) that never got picked up from the batch I sent a few months ago. - Enable GCC diagnostic context for value-tracking warnings This results in better GCC diagnostics for the value range tracking, so we can get better visibility into where those values are coming from when we get out-of-bounds warnings at compile time. * tag 'hardening-v6.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: kbuild: Enable GCC diagnostic context for value-tracking warnings string: Add missing kernel-doc return descriptions media: iris: Cast iris_hfi_gen2_get_instance() allocation type drm/plane: Remove const qualifier from plane->modifiers allocation type comedi: Adjust range_table_list allocation type

2025-12-05tpm2-sessions: Fix out of range indexing in name_sizeJarkko Sakkinen
'name_size' does not have any range checks, and it just directly indexes with TPM_ALG_ID, which could lead into memory corruption at worst. Address the issue by only processing known values and returning -EINVAL for unrecognized values. Make also 'tpm_buf_append_name' and 'tpm_buf_fill_hmac_session' fallible so that errors are detected before causing any spurious TPM traffic. End also the authorization session on failure in both of the functions, as the session state would be then by definition corrupted.

2025-12-04Merge tag 'for-linus-iommufd' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd Pull iommufd updates from Jason Gunthorpe: "This is a pretty consequential cycle for iommufd, though this pull is not too big. It is based on a shared branch with VFIO that introduces VFIO_DEVICE_FEATURE_DMA_BUF a DMABUF exporter for VFIO device's MMIO PCI BARs. This was a large multiple series journey over the last year and a half. Based on that work IOMMUFD gains support for VFIO DMABUF's in its existing IOMMU_IOAS_MAP_FILE, which closes the last major gap to support PCI peer to peer transfers within VMs. In Joerg's iommu tree we have the "generic page table" work which aims to consolidate all the duplicated page table code in every iommu driver into a single algorithm. This will be used by iommufd to implement unique page table operations to start adding new features and improve performance. In here: - Expand IOMMU_IOAS_MAP_FILE to accept a DMABUF exported from VFIO. This is the first step to broader DMABUF support in iommufd, right now it only works with VFIO. This closes the last functional gap with classic VFIO type 1 to safely support PCI peer to peer DMA by mapping the VFIO device's MMIO into the IOMMU. - Relax SMMUv3 restrictions on nesting domains to better support qemu's sequence to have an identity mapping before the vSID is established" * tag 'for-linus-iommufd' of git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd: iommu/arm-smmu-v3-iommufd: Allow attaching nested domain for GBPA cases iommufd/selftest: Add some tests for the dmabuf flow iommufd: Accept a DMABUF through IOMMU_IOAS_MAP_FILE iommufd: Have iopt_map_file_pages convert the fd to a file iommufd: Have pfn_reader process DMABUF iopt_pages iommufd: Allow MMIO pages in a batch iommufd: Allow a DMABUF to be revoked iommufd: Do not map/unmap revoked DMABUFs iommufd: Add DMABUF to iopt_pages vfio/pci: Add vfio_pci_dma_buf_iommufd_map()

Pull VFIO updates from Alex Williamson: - Move libvfio selftest artifacts in preparation of more tightly coupled integration with KVM selftests (David Matlack) - Fix comment typo in mtty driver (Chu Guangqing) - Support for new hardware revision in the hisi_acc vfio-pci variant driver where the migration registers can now be accessed via the PF. When enabled for this support, the full BAR can be exposed to the user (Longfang Liu) - Fix vfio cdev support for VF token passing, using the correct size for the kernel structure, thereby actually allowing userspace to provide a non-zero UUID token. Also set the match token callback for the hisi_acc, fixing VF token support for this this vfio-pci variant driver (Raghavendra Rao Ananta) - Introduce internal callbacks on vfio devices to simplify and consolidate duplicate code for generating VFIO_DEVICE_GET_REGION_INFO data, removing various ioctl intercepts with a more structured solution (Jason Gunthorpe) - Introduce dma-buf support for vfio-pci devices, allowing MMIO regions to be exposed through dma-buf objects with lifecycle managed through move operations. This enables low-level interactions such as a vfio-pci based SPDK drivers interacting directly with dma-buf capable RDMA devices to enable peer-to-peer operations. IOMMUFD is also now able to build upon this support to fill a long standing feature gap versus the legacy vfio type1 IOMMU backend with an implementation of P2P support for VM use cases that better manages the lifecycle of the P2P mapping (Leon Romanovsky, Jason Gunthorpe, Vivek Kasireddy) - Convert eventfd triggering for error and request signals to use RCU mechanisms in order to avoid a 3-way lockdep reported deadlock issue (Alex Williamson) - Fix a 32-bit overflow introduced via dma-buf support manifesting with large DMA buffers (Alex Mastro) - Convert nvgrace-gpu vfio-pci variant driver to insert mappings on fault rather than at mmap time. This conversion serves both to make use of huge PFNMAPs but also to both avoid corrected RAS events during reset by now being subject to vfio-pci-core's use of unmap_mapping_range(), and to enable a device readiness test after reset (Ankit Agrawal) - Refactoring of vfio selftests to support multi-device tests and split code to provide better separation between IOMMU and device objects.

git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux Pull gpio updates from Bartosz Golaszewski: "There's one new driver, lots of various updates to existing ones, some refactoring support for new models and misc tweaks and fixes. The biggest new feature in GPIO core is adding support for managed, enable-counted sharing of GPIO pins, something that - until now - was only hacked around with the GPIOD_FLAGS_BIT_NONEXCLUSIVE request flag which basically allowed drivers to "fight it out" for the descriptor and provided no synchronization. It was enabled on Qualcomm platforms (and thus is enabled on arm64 defconfig) and I plan on removing GPIOD_FLAGS_BIT_NONEXCLUSIVE once all drivers using it are switched to the new mechanism. GPIO core: - add proper support for shared GPIOs that's aiming to replace the current sharing mechanism (which provides no synchronization ot enable counting) and enable it for Qualcomm platforms - improve the software node GPIO lookup by using the fwnode representation instead of the software node's name which was prone to bugs (GPIO controllers don't have to use the software node's name as their kernel label) - remove the last user of legacy-of-mm-gpiochip.h and drop the header - move closer to removing the legacy gpio_request_one() routine - rename some symbols for consistency - shrink GPIO printk() helpers by reusing existing code - remove some redundant kernel messages - use min() instead of min_t() in GPIO ACPI code - use system_percpu_wq instead of system_wq in GPIO character device code New drivers: - add a driver for the QIXIS FPGA GPIO controller Driver improvements: - use modernized variants of power management macros across a wide array of drivers in order to avoid having to use the __maybe_unused attribute - convert gpio-elkhartlake and reset-gpio to using the auxiliary bus instead of the platform bus as they are not really described in firmware - use lock guards and update symbol prefixes in gpio-mmio - support the bryx radio interface kit in gpio-mpsse + refactor the driver - use software nodes for configuring the reset-gpio driver, including setting up the reference to the shared "reset" pin - check and propagate the return value of gpiod_set_value() to user-space in gpio-virtuser (this was previously not possible as this function returned void) - extend the gpio-regmap helper with more features (bypass cache for aliased inputs, force writes for aliased data registers, add a new configuration parameter) - remove unneeded includes from gpio-aspeed and gpio-latch - add support for Tegra410 to gpio-tegra186 - replace PCI-specific PM with generic device-level PM in gpio-bt8xx - use dynamic GPIO range allocation in gpio-loongson-64bit - improve handling of level-triggered interrupts in gpio-pca953x - add suspend/resume support to gpio-fxl6408 - add support for more models to gpio-menz127 - optimize gpio-mvebu interrupt handling by avoiding unnecessary calls to mvebu_gpio_irq_handler() - make locking more consistent in gpio-grgpio Device-tree bindings: - document new NXP and Microchip models Documentation: - add a comprehensive compatibility and feature list for gpio-pca953x, which is a great addition as it's probably the most commonly used GPIO expander driver - kernel-doc tweaks Late fixes: - use BYTE_CTRL_MODE for 2K2000/3000 models in gpio-loongson" * tag 'gpio-updates-for-v6.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (80 commits) gpio: loongson: Switch 2K2000/3000 GPIO to BYTE_CTRL_MODE gpio: regmap: fix kernel-doc notation gpio: shared: fix a deadlock gpio: shared-proxy: set suppress_bind_attrs gpio: shared: ignore GPIO hogs when traversing the device tree gpio: shared: ignore special __symbols__ node when traversing device tree gpio: shared: handle the reset-gpios corner case gpio: zynq: Use modern PM macros gpio: xilinx: Use modern PM macros gpio: xgene: Use modern PM macros gpio: uniphier: Use modern PM macros gpio: tqmx86: Use modern PM macros gpio: pch: Use modern PM macros gpio: omap: Use modern PM macros gpio: msc313: Use modern PM macros gpio: mlxbf2: Use modern PM macros gpio: ml-ioh: Use modern PM macros gpio: pl061: Use modern PM macros gpio: htc-egpio: Use modern PM macros gpio: brcmstb: Use modern PM macros ...

To identify such quirks at an early stages of device detection, the step for reading the configuration ROM contents has been changed. As a side effect, the entire detection process is now performed at the basic transaction speed (S100), without a trial to probe higher supported speeds. With this change, the following devices should now work with fewer issues: - TASCAM FW-1884, FW-1804, and FW-1082 - MOTU Audio Express - Safer removals of host card There was a race condition between host card removal and handling of bus reset events in the workqueue.

This is useful for IIO type applcations where you trigger an operation then read the result after a delay. - Add a tracepoint for flash exec_ops, bringing the flash support more in line with the debuggability of vanilla SPI. - Support for Airoha EN7523, Arduino MCUs, Aspeed AST2700, Microchip PolarFire SPI controllers, NXP i.MX51 ECSPI target mode, Qualcomm IPQ5414 and IPQ5332, Renesas RZ/T2H, RZ/V2N and RZ/2NH and SpacemiT K1 QuadSPI.

2025-12-04blk-mq: add blk_rq_nr_bvec() helperChaitanya Kulkarni
Add a new helper function blk_rq_nr_bvec() that returns the number of bvecs in a request. This count represents the number of iterations rq_for_each_bvec() would perform on a request. Drivers need to pre-allocate bvec arrays before iterating through a request's bvecs. Currently, they manually count bvecs using rq_for_each_bvec() in a loop, which is repetitive. The new helper centralizes this logic. This pattern exists in loop and zloop drivers, where multi-bio requests require copying bvecs into a contiguous array before creating an iov_iter for file operations. Update loop and zloop drivers to use the new helper, eliminating duplicate code. This patch also provides a clear API to avoid any potential misuse of blk_nr_phys_segments() for calculating the bvecs since, one bvec can have more than one segments and use of blk_nr_phys_segments() can lead to extra memory allocation :- [ 6155.673749] nullb_bio: 128K bio as ONE bvec: sector=0, size=131072 [ 6155.673846] null_blk: #### null_handle_data_transfer:1375 [ 6155.673850] null_blk: nr_bvec=1 blk_rq_nr_phys_segments=2 [ 6155.674263] null_blk: #### null_handle_data_transfer:1375 [ 6155.674267] null_blk: nr_bvec=1 blk_rq_nr_phys_segments=1 Reviewed-by: Niklas Cassel <cassel@kernel.org> Signed-off-by: Chaitanya Kulkarni <ckulkarnilinux@gmail.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>

The on-disk layout declarations have been moved into include/linux/hfs_common.h with the goal to exclude the declarations duplication and to keep the HFS/HFS+ on-disk layout declarations in one place.

2025-12-04f2fs: revert summary entry count from 2048 to 512 in 16kb block supportDaeho Jeong
The recent increase in the number of Segment Summary Area (SSA) entries from 512 to 2048 was an unintentional change in logic of 16kb block support. This commit corrects the issue. To better utilize the space available from the erroneous 2048-entry calculation, we are implementing a solution to share the currently unused SSA space with neighboring segments. This enhances overall SSA utilization without impacting the established 8MB segment size.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: "Core & protocols: - Replace busylock at the Tx queuing layer with a lockless list. Resulting in a 300% (4x) improvement on heavy TX workloads, sending twice the number of packets per second, for half the cpu cycles. - Allow constantly busy flows to migrate to a more suitable CPU/NIC queue. Normally we perform queue re-selection when flow comes out of idle, but under extreme circumstances the flows may be constantly busy. Add sysctl to allow periodic rehashing even if it'd risk packet reordering. - Optimize the NAPI skb cache, make it larger, use it in more paths. - Attempt returning Tx skbs to the originating CPU (like we already did for Rx skbs). - Various data structure layout and prefetch optimizations from Eric. - Remove ktime_get() from the recvmsg() fast path, ktime_get() is sadly quite expensive on recent AMD machines. - Extend threaded NAPI polling to allow the kthread busy poll for packets. - Make MPTCP use Rx backlog processing. This lowers the lock pressure, improving the Rx performance. - Support memcg accounting of MPTCP socket memory. - Allow admin to opt sockets out of global protocol memory accounting (using a sysctl or BPF-based policy). The global limits are a poor fit for modern container workloads, where limits are imposed using cgroups. - Improve heuristics for when to kick off AF_UNIX garbage collection. - Allow users to control TCP SACK compression, and default to 33% of RTT. - Add tcp_rcvbuf_low_rtt sysctl to let datacenter users avoid unnecessarily aggressive rcvbuf growth and overshot when the connection RTT is low. - Preserve skb metadata space across skb_push / skb_pull operations. - Support for IPIP encapsulation in the nftables flowtable offload. - Support appending IP interface information to ICMP messages (RFC 5837). - Support setting max record size in TLS (RFC 8449). - Remove taking rtnl_lock from RTM_GETNEIGHTBL and RTM_SETNEIGHTBL. - Use a dedicated lock (and RCU) in MPLS, instead of rtnl_lock. - Let users configure the number of write buffers in SMC. - Add new struct sockaddr_unsized for sockaddr of unknown length, from Kees. - Some conversions away from the crypto_ahash API, from Eric Biggers. - Some preparations for slimming down struct page. - YAML Netlink protocol spec for WireGuard. - Add a tool on top of YAML Netlink specs/lib for reporting commonly computed derived statistics and summarized system state. Driver API: - Add CAN XL support to the CAN Netlink interface. - Add uAPI for reporting PHY Mean Square Error (MSE) diagnostics, as defined by the OPEN Alliance's "Advanced diagnostic features for 100BASE-T1 automotive Ethernet PHYs" specification. - Add DPLL phase-adjust-gran pin attribute (and implement it in zl3073x). - Refactor xfrm_input lock to reduce contention when NIC offloads IPsec and performs RSS. - Add info to devlink params whether the current setting is the default or a user override. Allow resetting back to default. - Add standard device stats for PSP crypto offload. - Leverage DSA frame broadcast to implement simple HSR frame duplication for a lot of switches without dedicated HSR offload. - Add uAPI defines for 1.6Tbps link modes. Device drivers: - Add Motorcomm YT921x gigabit Ethernet switch support. - Add MUCSE driver for N500/N210 1GbE NIC series. - Convert drivers to support dedicated ops for timestamping control, and away from the direct IOCTL handling. While at it support GET operations for PHY timestamping. - Add (and convert most drivers to) a dedicated ethtool callback for reading the Rx ring count. - Significant refactoring efforts in the STMMAC driver, which supports Synopsys turn-key MAC IP integrated into a ton of SoCs. -

git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext Pull sched_ext updates from Tejun Heo: - Improve recovery from misbehaving BPF schedulers. When a scheduler puts many tasks with varying affinity restrictions on a shared DSQ, CPUs scanning through tasks they cannot run can overwhelm the system, causing lockups. Bypass mode now uses per-CPU DSQs with a load balancer to avoid this, and hooks into the hardlockup detector to attempt recovery. Add scx_cpu0 example scheduler to demonstrate this scenario. - Add lockless peek operation for DSQs to reduce lock contention for schedulers that need to query queue state during load balancing. - Allow scx_bpf_reenqueue_local() to be called from anywhere in preparation for deprecating cpu_acquire/release() callbacks in favor of generic BPF hooks. - Prepare for hierarchical scheduler support: add scx_bpf_task_set_slice() and scx_bpf_task_set_dsq_vtime() kfuncs, make scx_bpf_dsq_insert*() return bool, and wrap kfunc args in structs for future aux__prog parameter. - Implement cgroup_set_idle() callback to notify BPF schedulers when a cgroup's idle state changes. - Fix migration tasks being incorrectly downgraded from stop_sched_class to rt_sched_class across sched_ext enable/disable.

Otherwise, the driver would rely on the kthread. It is going to be used as the-best-effort approach for an experimental nbcon netconsole driver, see https://lore.kernel.org/r/20251121-nbcon-v1-2-503d17b2b4af@debian.org Note that a safe .write_atomic() callback is supposed to work in NMI context. But some networking drivers are not safe even in IRQ context: https://lore.kernel.org/r/oc46gdpmmlly5o44obvmoatfqo5bhpgv7pabpvb6sjuqioymcg@gjsma3ghoz35 In an ideal world, all networking drivers would be fixed first and the atomic flush would be blocked only in NMI context. But it brings the question how reliable networking drivers are when the system is in a bad state. They might block flushing more reliable serial consoles which are more suitable for serious debugging anyway. - Allow to use the last 4 bytes of the printk ring buffer. - Prevent queuing IRQ work and block printk kthreads when consoles are suspended. Otherwise, they create non-necessary churn or even block the suspend. - Release console_lock() between each record in the kthread used for legacy consoles on RT. It might significantly speed up the boot. - Release nbcon context between each record in the atomic flush. It prevents stalls of the related printk kthread after it has lost the ownership in the middle of a record - Add support for NBCON consoles into KDB - Add %ptsP modifier for printing struct timespec64 and use it where possible - Misc code clean up * tag 'printk-for-6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux: (48 commits) printk: Use console_is_usable on console_unblank arch: um: kmsg_dump: Use console_is_usable drivers: serial: kgdboc: Drop checks for CON_ENABLED and CON_BOOT lib/vsprintf: Unify FORMAT_STATE_NUM handlers printk: Avoid irq_work for printk_deferred() on suspend printk: Avoid scheduling irq_work on suspend printk: Allow printk_trigger_flush() to flush all types tracing: Switch to use %ptSp scsi: snic: Switch to use %ptSp scsi: fnic: Switch to use %ptSp s390/dasd: Switch to use %ptSp ptp: ocp: Switch to use %ptSp pps: Switch to use %ptSp PCI: epf-test: Switch to use %ptSp net: dsa: sja1105: Switch to use %ptSp mmc: mmc_test: Switch to use %ptSp media: av7110: Switch to use %ptSp ipmi: Switch to use %ptSp igb: Switch to use %ptSp e1000e: Switch to use %ptSp ...

git://git.kernel.org/pub/scm/linux/kernel/git/rcu/linux Pull RCU updates from Frederic Weisbecker: "SRCU: - Properly handle SRCU readers within IRQ disabled sections in tiny SRCU - Preparation to reimplement RCU Tasks Trace on top of SRCU fast: - Introduce API to expedite a grace period and test it through rcutorture - Split srcu-fast in two flavours: SRCU-fast and SRCU-fast-updown. Both are still targeted toward faster readers (without full barriers on LOCK and UNLOCK) at the expense of heavier write side (using full RCU grace period ordering instead of simply full ordering) as compared to "traditional" non-fast SRCU. But those srcu-fast flavours are going to be optimized in two different ways: - SRCU-fast will become the reimplementation basis for RCU-TASK-TRACE for consolidation. Since RCU-TASK-TRACE must be NMI safe, SRCU-fast must be as well. - SRCU-fast-updown will be needed for uretprobes code in order to get rid of the read-side memory barriers while still allowing entering the reader at task level while exiting it in a timer handler. It is considered semaphore-like in that it can have different owners between LOCK and UNLOCK. However it is not NMI-safe. The actual optimizations are work in progress for the next cycle. Only the new interfaces are added for now, along with related torture and scalability test code. - Create/document/debug/torture new proper initializers for RCU fast: DEFINE_SRCU_FAST() and init_srcu_struct_fast() This allows for using right away the proper ordering on the write side (either full ordering or full RCU grace period ordering) without waiting for the read side to tell which to use. This also optimizes the read side altogether with moving flavour debug checks under debug config and with removing a costly RmW operation on their first call. - Make some diagnostic functions tracing safe Refscale: - Add performance testing for common context synchronizations (Preemption, IRQ, Softirq) and per-cpu increments. Those are relevant comparisons against SRCU-fast read side APIs, especially as they are planned to synchronize further tracing fast-path code Miscellanous: - In order to prepare the layout for nohz_full work deferral to user exit, the context tracking state must shrink the counter of transitions to/from RCU not watching. The only possible hazard is to trigger wrap-around more easily, delaying a bit grace periods when that happens. This should be a rare event though. Yet add debugging and torture code to test that assumption - Fix memory leak on locktorture module - Annotate accesses in rculist_nulls.h to prevent from KCSAN warnings. On recent discussions, we also concluded that all those WRITE_ONCE() and READ_ONCE() on list APIs deserve appropriate comments. Something to be expected for the next cycle - Provide a script to apply several configs to several commits with torture - Allow torture to reuse a build directory in order to save needless rebuild time - Various cleanups" * tag 'rcu.release.v6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/rcu/linux: (29 commits) refscale: Add SRCU-fast-updown readers refscale: Exercise DEFINE_STATIC_SRCU_FAST() and init_srcu_struct_fast() rcutorture: Make srcu{,d}_torture_init() announce the SRCU type srcu: Create an SRCU-fast-updown API refscale: Do not disable interrupts for tests involving local_bh_enable() refscale: Add non-atomic per-CPU increment readers refscale: Add this_cpu_inc() readers refscale: Add preempt_disable() readers refscale: Add local_bh_disable() readers refscale: Add local_irq_disable() and local_irq_save() readers torture: Permit negative kvm.sh --kconfig numberic arguments srcu: Add SRCU_READ_FLAVOR_FAST_UPDOWN CPP macro rcu: Mark diagnostic functions as notrace rcutorture: Make TREE04 use CONFIG_RCU_DYNTICKS_TORTURE rcutorture: Remove redundant rcutorture_one_extend() from rcu_torture_one_read() rcutorture: Permit kvm-again.sh to re-use the build directory torture: Add kvm-series.sh to test commit/scenario combination rcu: use WRITE_ONCE() for ->next and ->pprev of hlist_nulls locktorture: Fix memory leak in param_set_cpumask() doc: Update for SRCU-fast definitions and initialization ...
