2025-05-23Drivers: hv: vmbus: Introduce hv_get_vmbus_root_device()Roman Kisel
The ARM64 PCI code for hyperv needs to know the VMBus root device, and it is private. Provide a function that returns it. Rename it from "hv_dev" as "hv_dev" as a symbol is very overloaded. No functional changes.

2025-05-23arm64: kvm, smccc: Introduce and use API for getting hypervisor UUIDRoman Kisel
The KVM/arm64 uses SMCCC to detect hypervisor presence. That code is private, and it follows the SMCCC specification. Other existing and emerging hypervisor guest implementations can and should use that standard approach as well. Factor out a common infrastructure that the guests can use, update KVM to employ the new API. The central notion of the SMCCC method is the UUID of the hypervisor, and the new API follows that. No functional changes. Validated with a KVM/arm64 guest.

2025-05-23fs: convert mount flags to enumStephen Brennan
In prior kernel versions (5.8-6.8), commit 9f6c61f96f2d9 ("proc/mounts: add cursor") introduced MNT_CURSOR, a flag used by readers from /proc/mounts to keep their place while reading the file. Later, commit 2eea9ce4310d8 ("mounts: keep list of mounts in an rbtree") removed this flag and its value has since been repurposed. For debuggers iterating over the list of mounts, cursors should be skipped as they are irrelevant. Detecting whether an element is a cursor can be difficult. Since the MNT_CURSOR flag is a preprocessor constant, it's not present in debuginfo, and since its value is repurposed, we cannot hard-code it. For this specific issue, cursors are possible to detect in other ways, but ideally, we would be able to read the mount flag definitions out of the debuginfo. For that reason, convert the mount flags to an enum.

2025-05-23netfilter: nf_tables: Have a list of nf_hook_ops in nft_hookPhil Sutter
Supporting a 1:n relationship between nft_hook and nf_hook_ops is convenient since a chain's or flowtable's nft_hooks may remain in place despite matching interfaces disappearing. This stabilizes ruleset dumps in that regard and opens the possibility to claim newly added interfaces which match the spec. Also it prepares for wildcard interface specs since these will potentially match multiple interfaces. All spots dealing with hook registration are updated to handle a list of multiple nf_hook_ops, but nft_netdev_hook_alloc() only adds a single item for now to retain the old behaviour. The only expected functional change here is how vanishing interfaces are handled: Instead of dropping the respective nft_hook, only the matching nf_hook_ops are dropped. To safely remove individual ops from the list in netdev handlers, an rcu_head is added to struct nf_hook_ops so kfree_rcu() may be used. There is at least nft_flowtable_find_dev() which may be iterating through the list at the same time. Signed-off-by: Phil Sutter <phil@nwl.cc> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2025-05-23netfilter: conntrack: make nf_conntrack_id callable without a module dependencyFlorian Westphal
While nf_conntrack_id() doesn't need any functionaliy from conntrack, it does reside in nf_conntrack_core.c -- callers add a module dependency on conntrack. Followup patch will need to compute the conntrack id from nf_tables_trace.c to include it in nf_trace messages emitted to userspace via netlink. I don't want to introduce a module dependency between nf_tables and conntrack for this. Since trace is slowpath, the added indirection is ok. One alternative is to move nf_conntrack_id to the netfilter/core.c, but I don't see a compelling reason so far.

2025-05-23af_unix: Move SOCK_PASS{CRED,PIDFD,SEC} to struct sock.Kuniyuki Iwashima
As explained in the next patch, SO_PASSRIGHTS would have a problem if we assigned a corresponding bit to socket->flags, so it must be managed in struct sock. Mixing socket->flags and sk->sk_flags for similar options will look confusing, and sk->sk_flags does not have enough space on 32bit system. Also, as mentioned in commit 16e572626961 ("af_unix: dont send SCM_CREDENTIALS by default"), SOCK_PASSCRED and SOCK_PASSPID handling is known to be slow, and managing the flags in struct socket cannot avoid that for embryo sockets. Let's move SOCK_PASS{CRED,PIDFD,SEC} to struct sock. While at it, other SOCK_XXX flags in net.h are grouped as enum. Note that assign_bit() was atomic, so the writer side is moved down after lock_sock() in setsockopt(), but the bit is only read once in sendmsg() and recvmsg(), so lock_sock() is not needed there.

2025-05-23netfs: Fix undifferentiation of DIO reads from unbuffered readsDavid Howells
On cifs, "DIO reads" (specified by O_DIRECT) need to be differentiated from "unbuffered reads" (specified by cache=none in the mount parameters). The difference is flagged in the protocol and the server may behave differently: Windows Server will, for example, mandate that DIO reads are block aligned. Fix this by adding a NETFS_UNBUFFERED_READ to differentiate this from NETFS_DIO_READ, parallelling the write differentiation that already exists. cifs will then do the right thing.

2025-05-22mm: remove WARN_ON_ONCE() in file_has_valid_mmap_hooks()Lorenzo Stoakes
Having encountered a trinity report in linux-next (Linked in the 'Closes' tag) it appears that there are legitimate situations where a file-backed mapping can be acquired but no file->f_op->mmap or file->f_op->mmap_prepare is set, at which point do_mmap() should simply error out with -ENODEV. Since previously we did not warn in this scenario and it appears we rely upon this, restore this situation, while retaining a WARN_ON_ONCE() for the case where both are set, which is absolutely incorrect and must be addressed and thus always requires a warning. If further work is required to chase down precisely what is causing this, then we can later restore this, but it makes no sense to hold up this series to do so, as this is existing and apparently expected behaviour.

2025-05-22mm: convert VM_PFNMAP tracking to pfnmap_track() + pfnmap_untrack()David Hildenbrand
Let's use our new interface. In remap_pfn_range(), we'll now decide whether we have to track (full VMA covered) or only lookup the cachemode (partial VMA covered). Remember what we have to untrack by linking it from the VMA. When duplicating VMAs (e.g., splitting, mremap, fork), we'll handle it similar to anon VMA names, and use a kref to share the tracking. Once the last VMA un-refs our tracking data, we'll do the untracking, which simplifies things a lot and should sort our various issues we saw recently, for example, when partially unmapping/zapping a tracked VMA. This change implies that we'll keep tracking the original PFN range even after splitting + partially unmapping it: not too bad, because it was not working reliably before. The only thing that kind-of worked before was shrinking such a mapping using mremap(): we managed to adjust the reservation in a hacky way, now we won't adjust the reservation but leave it around until all involved VMAs are gone. If that ever turns out to be an issue, we could hook into VM splitting code and split the tracking; however, that adds complexity that might not be required, so we'll keep it simple for now.

Other subsystems may make use of the cgroup hierarchy with the cgroup_bpf support being one such example. For such a feature, it's useful to be able to hook into cgroup creation and destruction paths to perform feature-specific initializations and cleanups. Add cgroup_lifetime_notifier which generates CGROUP_LIFETIME_ONLINE and CGROUP_LIFETIME_OFFLINE events whenever cgroups are created and destroyed, respectively. The next patch will convert cgroup_bpf to use the new notifier and other uses are planned. Signed-off-by: Tejun Heo <tj@kernel.org>

There is a known merge conflict due to changes in neighbouring lines. Stephen's resolution in linux-next is: https://lore.kernel.org/linux-next/20250506155728.65605bae@canb.auug.org.au/ Added 3 named IIO reviewers to MAINTAINERS. This is a reflection of those who have been doing much of this work for some time. Lars-Peter is removed from the entry having moved on to other topics. Thanks Nuno, David and Andy for stepping up and Lars-Peter for all your hard work in the past! Includes the usual mix of new device support, features and general cleanup. This time we also have some tree wide changes. - Rip out the iio_device_claim_direct_scoped() as it proved hard to work with. This series includes quite a few related cleanups such as use of guard or factoring code out to allow direct returns. - Switch from iio_device_claim/release_direct_mode() to new iio_device_claim/release_direct() which is structured so that sparse can warn on failed releases. There were a few false positives but those were mostly in code that benefited from being cleaned up as part of this process. - Introduce iio_push_to_buffers_with_ts() to replace the _timestamp() version over time. This version takes the size of the supplied buffer which the core checks is at least as big as expected by calculation from channel descriptions of those channels enabled. Use this in an initial set of drivers. - Add macros for IIO_DECLARE_BUFFER_WITH_TS() and IIO_DECLARE_DMA_BUFFER_WITH_TS() to avoid lots of fiddly code to ensure correctly aligned buffers for timestamps being added onto the end of channel data. New device support ------------------ adi,ad3530r - New driver for AD3530, AD3530R, AD3531 and AD3531R DACs with programmable gain controls. R variants have internal references. adi,ad7476 - Add support (dt compatible only) for the Rohm BU79100G ADC which is fully compatible with the ti,ads7866. adi,ad7606 - Support ad7606c-16 and ad7606c-18 devices. Includes switch to dynamic channel information allocation. adi,ad7380 - Add support for the AD7389-4 dfrobot,sen0322 - New driver for this oxygen sensor. mediatek,mt2701-auxadc - Add binding for MT6893 which is fully compatible with already supported MT8173. meson-saradc - Support the GXLX SoCs. Mostly this is a workaround for some unrelated clock control bits found in the ADC register map. nuvoton,nct7201 - New driver for NCT7201 and NCT7202 I2C ADCs. rohm,bd79124 - New driver for this 12-bit, 8-channel SAR ADC. - Switch to new set_rv etc gpio callbacks that were added in 6.15. rohm,bd79703 - Add support for BD79700, BD79701 and BD79702 DACs that have subsets of functionality of the already supported bd79703. Included making this driver suitable for support device variants. st,stm32-lptimer - Add support for stm32pm25 to this trigger. Features -------- Beyond IIO - Property iterator for named children. core - Enable writes for 64 bit integers used for standard IIO ABI elements. Previously these could be read only. - Helper library that should avoid code duplication for simpler ADC bindings that have a child node per channel. - Enforce that IIO_DMA_MINALIGN is always at least 8 (almost always true and simplifies code on all significant architectures) core/backend - Add support to control source of data - useful when the HDL includes things like generated ramps for testing purposes. Enable this for adi-axi-dac adi,ad3552-hs - Add debugfs related callbacks to allow debug access to register contents. adi,ad4000 - Support SPI offload with appropriate FPGA firmware along with improving documentation. adi,ad7293 - Add support for external reference voltage. adi,ad7606 - Support SPI offload. adi,ad7768-1 - Support reset GPIO. adi,admv8818 - Support filter frequencies beyond 2^32. adi,adxl345 - Add single and double tap events. hid-sensor-prox - Support 16-bit report sizes as seen on some Intel platforms. invensense,icm42600 - Enable use of named interrupts to avoid problems with some wiring choices. Get the interrupt by name, but fallback to previous assumption on the first being INT1 if no names are supplied. microchip,mcp3911 - Add reset gpio support. rohm,bh7150 - Add reset gpio support. st,stm32 - Add support to control oversampling. ti,adc128s052 - Add support for ROHM BD79104 which is early compatible with the TI parts already supported by this driver.

2025-05-22net: Add support for providing the PTP hardware source in tsinfoKory Maincent
Multi-PTP source support within a network topology has been merged, but the hardware timestamp source is not yet exposed to users. Currently, users only see the PTP index, which does not indicate whether the timestamp comes from a PHY or a MAC. Add support for reporting the hwtstamp source using a hwtstamp-source field, alongside hwtstamp-phyindex, to describe the origin of the hardware timestamp. Remove HWTSTAMP_SOURCE_UNSPEC enum value as it is not used at all.

2025-05-22regmap: irq: Add support for chips without separate IRQ statusMathieu Dubois-Briand
Some GPIO chips allow to rise an IRQ on GPIO level changes but do not provide an IRQ status for each separate line: only the current gpio level can be retrieved. Add support for these chips, emulating IRQ status by comparing GPIO levels with the levels during the previous interrupt.

2025-05-22spi: use container_of_cont() for to_spi_device()Greg Kroah-Hartman
Some places in the spi core pass in a const pointer to a device and the default container_of() casts that away, which is not a good idea. Preserve the proper const attribute by using container_of_const() for to_spi_device() instead, which is what it was designed for. Note, this removes the NULL check for a device pointer in the call, but no one was ever checking for that return value, and a device pointer should never be NULL overall anyway, so this should be a safe change.

2025-05-22regulator: bcm590xx: Store regulator descriptions in tableArtur Weber
Instead of filling in the regulator description programatically, store the data in a struct. This will make it a bit nicer to introduce support for other BCM590xx chips besides the BCM59056. To do this, add a new struct type, bcm590xx_reg_data, to store all of the necessary information. Drop the old IS_LDO, IS_GPLDO... macros in favor of the "type" field in this struct. Adapt the old bcm590xx_reg struct to the new types.
