2025-09-03of/irq: Convert of_msi_map_id() callers to of_msi_xlate()Lorenzo Pieralisi
With the introduction of the of_msi_xlate() function, the OF layer provides an API to map a device ID and retrieve the MSI controller node the ID is mapped to with a single call. of_msi_map_id() is currently used to map a deviceID to a specific MSI controller node; of_msi_xlate() can be used for that purpose too, there is no need to keep the two functions. Convert of_msi_map_id() to of_msi_xlate() calls and update the of_msi_xlate() documentation to describe how the struct device_node pointer passed in should be set-up to either provide the MSI controller node target or receive its pointer upon mapping completion.

2025-09-03vdso/vsyscall: Avoid slow division loop in auxiliary clock updateThomas Weißschuh
The call to __iter_div_u64_rem() in vdso_time_update_aux() is a wrapper around subtraction. It cannot be used to divide large numbers, as that introduces long, computationally expensive delays. A regular u64 division is also not possible in the timekeeper update path as it can be too slow. Instead of splitting the ktime_t offset into into second and subsecond components during the timekeeper update fast-path, do it together with the adjustment of tk->offs_aux in the slow-path. Equivalent to the handling of offs_boot and monotonic_to_boot. Reuse the storage of monotonic_to_boot for the new field, as it is not used by auxiliary timekeepers.

2025-09-03sched/fair: Get rid of sched_domains_curr_level hack for tl->cpumask()Peter Zijlstra
Leon [1] and Vinicius [2] noted a topology_span_sane() warning during their testing starting from v6.16-rc1. Debug that followed pointed to the tl->mask() for the NODE domain being incorrectly resolved to that of the highest NUMA domain. tl->mask() for NODE is set to the sd_numa_mask() which depends on the global "sched_domains_curr_level" hack. "sched_domains_curr_level" is set to the "tl->numa_level" during tl traversal in build_sched_domains() calling sd_init() but was not reset before topology_span_sane(). Since "tl->numa_level" still reflected the old value from build_sched_domains(), topology_span_sane() for the NODE domain trips when the span of the last NUMA domain overlaps. Instead of replicating the "sched_domains_curr_level" hack, get rid of it entirely and instead, pass the entire "sched_domain_topology_level" object to tl->cpumask() function to prevent such mishap in the future. sd_numa_mask() now directly references "tl->numa_level" instead of relying on the global "sched_domains_curr_level" hack to index into sched_domains_numa_masks[]. The original warning was reproducible on the following NUMA topology reported by Leon: $ sudo numactl -H available: 5 nodes (0-4) node 0 cpus: 0 1 node 0 size: 2927 MB node 0 free: 1603 MB node 1 cpus: 2 3 node 1 size: 3023 MB node 1 free: 3008 MB node 2 cpus: 4 5 node 2 size: 3023 MB node 2 free: 3007 MB node 3 cpus: 6 7 node 3 size: 3023 MB node 3 free: 3002 MB node 4 cpus: 8 9 node 4 size: 3022 MB node 4 free: 2718 MB node distances: node 0 1 2 3 4 0: 10 39 38 37 36 1: 39 10 38 37 36 2: 38 38 10 37 36 3: 37 37 37 10 36 4: 36 36 36 36 10 The above topology can be mimicked using the following QEMU cmd that was used to reproduce the warning and test the fix: sudo qemu-system-x86_64 -enable-kvm -cpu host \ -m 20G -smp cpus=10,sockets=10 -machine q35 \ -object memory-backend-ram,size=4G,id=m0 \ -object memory-backend-ram,size=4G,id=m1 \ -object memory-backend-ram,size=4G,id=m2 \ -object memory-backend-ram,size=4G,id=m3 \ -object memory-backend-ram,size=4G,id=m4 \ -numa node,cpus=0-1,memdev=m0,nodeid=0 \ -numa node,cpus=2-3,memdev=m1,nodeid=1 \ -numa node,cpus=4-5,memdev=m2,nodeid=2 \ -numa node,cpus=6-7,memdev=m3,nodeid=3 \ -numa node,cpus=8-9,memdev=m4,nodeid=4 \ -numa dist,src=0,dst=1,val=39 \ -numa dist,src=0,dst=2,val=38 \ -numa dist,src=0,dst=3,val=37 \ -numa dist,src=0,dst=4,val=36 \ -numa dist,src=1,dst=0,val=39 \ -numa dist,src=1,dst=2,val=38 \ -numa dist,src=1,dst=3,val=37 \ -numa dist,src=1,dst=4,val=36 \ -numa dist,src=2,dst=0,val=38 \ -numa dist,src=2,dst=1,val=38 \ -numa dist,src=2,dst=3,val=37 \ -numa dist,src=2,dst=4,val=36 \ -numa dist,src=3,dst=0,val=37 \ -numa dist,src=3,dst=1,val=37 \ -numa dist,src=3,dst=2,val=37 \ -numa dist,src=3,dst=4,val=36 \ -numa dist,src=4,dst=0,val=36 \ -numa dist,src=4,dst=1,val=36 \ -numa dist,src=4,dst=2,val=36 \ -numa dist,src=4,dst=3,val=36 \ ...

2025-09-02bitmap: introduce hardware-specific bitfield operationsNicolas Frattaroli
Hardware of various vendors, but very notably Rockchip, often uses 32-bit registers where the upper 16-bit half of the register is a write-enable mask for the lower half. This type of hardware setup allows for more granular concurrent register write access. Over the years, many drivers have hand-rolled their own version of this macro, usually without any checks, often called something like HIWORD_UPDATE or FIELD_PREP_HIWORD, commonly with slightly different semantics between them. Clearly there is a demand for such a macro, and thus the demand should be satisfied in a common header file. As this is a convention that spans across multiple vendors, and similar conventions may also have cross-vendor adoption, it's best if it lives in a vendor-agnostic header file that can be expanded over time. Add hw_bitfield.h with two macros: FIELD_PREP_WM16, and FIELD_PREP_WM16_CONST. The latter is a version that can be used in initializers, like FIELD_PREP_CONST.

2025-09-02cxl, acpi/hmat: Update CXL access coordinates directly instead of through HMATDave Jiang
The current implementation of CXL memory hotplug notifier gets called before the HMAT memory hotplug notifier. The CXL driver calculates the access coordinates (bandwidth and latency values) for the CXL end to end path (i.e. CPU to endpoint). When the CXL region is onlined, the CXL memory hotplug notifier writes the access coordinates to the HMAT target structs. Then the HMAT memory hotplug notifier is called and it creates the access coordinates for the node sysfs attributes. During testing on an Intel platform, it was found that although the newly calculated coordinates were pushed to sysfs, the sysfs attributes for the access coordinates showed up with the wrong initiator. The system has 4 nodes (0, 1, 2, 3) where node 0 and 1 are CPU nodes and node 2 and 3 are CXL nodes. The expectation is that node 2 would show up as a target to node 0: /sys/devices/system/node/node2/access0/initiators/node0 However it was observed that node 2 showed up as a target under node 1: /sys/devices/system/node/node2/access0/initiators/node1 The original intent of the 'ext_updated' flag in HMAT handling code was to stop HMAT memory hotplug callback from clobbering the access coordinates after CXL has injected its calculated coordinates and replaced the generic target access coordinates provided by the HMAT table in the HMAT target structs. However the flag is hacky at best and blocks the updates from other CXL regions that are onlined in the same node later on. Remove the 'ext_updated' flag usage and just update the access coordinates for the nodes directly without touching HMAT target data. The hotplug memory callback ordering is changed. Instead of changing CXL, move HMAT back so there's room for the levels rather than have CXL share the same level as SLAB_CALLBACK_PRI. The change will resulting in the CXL callback to be executed after the HMAT callback. With the change, the CXL hotplug memory notifier runs after the HMAT callback. The HMAT callback will create the node sysfs attributes for access coordinates. The CXL callback will write the access coordinates to the now created node sysfs attributes directly and will not pollute the HMAT target values. A nodemask is introduced to keep track if a node has been updated and prevents further updates.

2025-09-02ptp: add helpers to get the phc_index by of_node or devWei Fang
Some Ethernet controllers do not have an integrated PTP timer function. Instead, the PTP timer is a separated device and provides PTP hardware clock to the Ethernet controller to use. Therefore, the Ethernet controller driver needs to obtain the PTP clock's phc_index in its ethtool_ops::get_ts_info(). Currently, most drivers implement this in the following ways. 1. The PTP device driver adds a custom API and exports it to the Ethernet controller driver. 2. The PTP device driver adds private data to its device structure. So the private data structure needs to be exposed to the Ethernet controller driver. When registering the ptp clock, ptp_clock_register() always saves the ptp_clock pointer to the private data of ptp_clock::dev. Therefore, as long as ptp_clock::dev is obtained, the phc_index can be obtained. So the following generic APIs can be added to the ptp driver to obtain the phc_index. 1. ptp_clock_index_by_dev(): Obtain the phc_index by the device pointer of the PTP device. 2.ptp_clock_index_by_of_node(): Obtain the phc_index by the of_node pointer of the PTP device. Also, we can add another API like ptp_clock_index_by_fwnode() to get the phc_index by fwnode of PTP device. However, this API is not used in this patch set, so it is better to add it when needed.

2025-09-01copy_process: pass clone_flags as u64 across calltreeSimon Schuster
With the introduction of clone3 in commit 7f192e3cd316 ("fork: add clone3") the effective bit width of clone_flags on all architectures was increased from 32-bit to 64-bit, with a new type of u64 for the flags. However, for most consumers of clone_flags the interface was not changed from the previous type of unsigned long. While this works fine as long as none of the new 64-bit flag bits (CLONE_CLEAR_SIGHAND and CLONE_INTO_CGROUP) are evaluated, this is still undesirable in terms of the principle of least surprise. Thus, this commit fixes all relevant interfaces of callees to sys_clone3/copy_process (excluding the architecture-specific copy_thread) to consistently pass clone_flags as u64, so that no truncation to 32-bit integers occurs on 32-bit architectures.

2025-08-29pppoe: remove rwlock usageQingfang Deng
Like ppp_generic.c, convert the PPPoE socket hash table to use RCU for lookups and a spinlock for updates. This removes rwlock usage and allows lockless readers on the fast path. - Mark hash table and list pointers as __rcu. - Use spin_lock() to protect writers. - Readers use rcu_dereference() under rcu_read_lock(). All known callers of get_item() already hold the RCU read lock, so no additional locking is needed. - get_item() now uses refcount_inc_not_zero() instead of sock_hold() to safely take a reference. This prevents crashes if a socket is already in the process of being freed (sk_refcnt == 0). - Set SOCK_RCU_FREE to defer socket freeing until after an RCU grace period. - Move skb_queue_purge() into sk_destruct callback to ensure purge happens after an RCU grace period.

2025-08-29Add RWF_NOSIGNAL flag for pwritev2Lauri Vasama
For a user mode library to avoid generating SIGPIPE signals (e.g. because this behaviour is not portable across operating systems) is cumbersome. It is generally bad form to change the process-wide signal mask in a library, so a local solution is needed instead. For I/O performed directly using system calls (synchronous or readiness based asynchronous) this currently involves applying a thread-specific signal mask before the operation and reverting it afterwards. This can be avoided when it is known that the file descriptor refers to neither a pipe nor a socket, but a conservative implementation must always apply the mask. This incurs the cost of two additional system calls. In the case of sockets, the existing MSG_NOSIGNAL flag can be used with send. For asynchronous I/O performed using io_uring, currently the only option (apart from MSG_NOSIGNAL for sockets), is to mask SIGPIPE entirely in the call to io_uring_enter. Thankfully io_uring_enter takes a signal mask, so only a single syscall is needed. However, copying the signal mask on every call incurs a non-zero performance penalty. Furthermore, this mask applies to all completions, meaning that if the non-signaling behaviour is desired only for some subset of operations, the desired signals must be raised manually from user-mode depending on the completed operation. Add RWF_NOSIGNAL flag for pwritev2. This flag prevents the SIGPIPE signal from being raised when writing on disconnected pipes or sockets. The flag is handled directly by the pipe filesystem and converted to the existing MSG_NOSIGNAL flag for sockets.

2025-08-28x86/apic: Add new driver for Secure AVICNeeraj Upadhyay
The Secure AVIC feature provides SEV-SNP guests hardware acceleration for performance sensitive APIC accesses while securely managing the guest-owned APIC state through the use of a private APIC backing page. This helps prevent the hypervisor from generating unexpected interrupts for a vCPU or otherwise violate architectural assumptions around the APIC behavior. Add a new x2APIC driver that will serve as the base of the Secure AVIC support. It is initially the same as the x2APIC physical driver (without IPI callbacks), but will be modified as features are implemented. As the new driver does not implement Secure AVIC features yet, if the hypervisor sets the Secure AVIC bit in SEV_STATUS, maintain the existing behavior to enforce the guest termination.

When a packet flood hits one or more RAW sockets, many cpus have to update sk->sk_drops. This slows down other cpus, because currently sk_drops is in sock_write_rx group.
