2025-03-21hwmon: (acpi_power_meter) Replace the deprecated hwmon_device_registerHuisong Li
When load this mode, we can see the following log: "power_meter ACPI000D:00: hwmon_device_register() is deprecated. Please convert the driver to use hwmon_device_register_with_info()." So replace hwmon_device_register with hwmon_device_register_with_info. These attributes, 'power_accuracy', 'power_cap_hyst', 'power_average_min' and 'power_average_max', should have been placed in hwmon_chip_info as power data type. But these attributes are displayed as string format on the following case: a) power1_accuracy --> display like '90.0%' b) power1_cap_hyst --> display 'unknown' when its value is 0xFFFFFFFF c) power1_average_min/max --> display 'unknown' when its value is negative. To avoid any changes in the display of these sysfs interfaces, we can't modifiy the type of these attributes in hwmon core and have to put them to extra_groups. Please note that the path of these sysfs interfaces are modified accordingly if use hwmon_device_register_with_info(): old: all sysfs interfaces are under acpi device, namely, /sys/class/hwmon/hwmonX/device/ now: all sysfs interfaces are under hwmon device, namely, /sys/class/hwmon/hwmonX/ The new ABI does not guarantee that the underlying path remains the same. But we have to accept this change so as to replace the deprecated API. Fortunately, some userspace application, like libsensors, would scan the two path and handles this automatically. So we can accept this change so as to drop the deprecated message.

2025-03-21arm: defconfig: drop RT_GROUP_SCHED=y from bcm2835/tegra/omap2plusCeleste Liu
Commit 673ce00c5d6c ("ARM: omap2plus_defconfig: Add support for distros with systemd") said it's because of recommendation from systemd. But systemd changed their recommendation later.[1] For cgroup v1, if turned on, and there's any cgroup in the "cpu" hierarchy it needs an RT budget assigned, otherwise the processes in it will not be able to get RT at all. The problem with RT group scheduling is that it requires the budget assigned but there's no way we could assign a default budget, since the values to assign are both upper and lower time limits, are absolute, and need to be sum up to < 1 for each individal cgroup. That means we cannot really come up with values that would work by default in the general case.[2] For cgroup v2, it's almost unusable as well. If it turned on, the cpu controller can only be enabled when all RT processes are in the root cgroup. But it will lose the benefits of cgroup v2 if all RT process were placed in the same cgroup. Red Hat, Gentoo, Arch Linux and Debian all disable it. systemd also doesn't support it.

2025-03-21netfilter: fib: avoid lookup if socket is availableFlorian Westphal
In case the fib match is used from the input hook we can avoid the fib lookup if early demux assigned a socket for us: check that the input interface matches sk-cached one. Rework the existing 'lo bypass' logic to first check sk, then for loopback interface type to elide the fib lookup. This speeds up fib matching a little, before: 93.08 GBit/s (no rules at all) 75.1 GBit/s ("fib saddr . iif oif missing drop" in prerouting) 75.62 GBit/s ("fib saddr . iif oif missing drop" in input) After: 92.48 GBit/s (no rules at all) 75.62 GBit/s (fib rule in prerouting) 90.37 GBit/s (fib rule in input). Numbers for the 'no rules' and 'prerouting' are expected to closely match in-between runs, the 3rd/input test case exercises the the 'avoid lookup if cached ifindex in sk matches' case. Test used iperf3 via veth interface, lo can't be used due to existing loopback test. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2025-03-21PCI/MSI: Convert pci_msi_ignore_mask to per MSI domain flagRoger Pau Monne
Setting pci_msi_ignore_mask inhibits the toggling of the mask bit for both MSI and MSI-X entries globally, regardless of the IRQ chip they are using. Only Xen sets the pci_msi_ignore_mask when routing physical interrupts over event channels, to prevent PCI code from attempting to toggle the maskbit, as it's Xen that controls the bit. However, the pci_msi_ignore_mask being global will affect devices that use MSI interrupts but are not routing those interrupts over event channels (not using the Xen pIRQ chip). One example is devices behind a VMD PCI bridge. In that scenario the VMD bridge configures MSI(-X) using the normal IRQ chip (the pIRQ one in the Xen case), and devices behind the bridge configure the MSI entries using indexes into the VMD bridge MSI table. The VMD bridge then demultiplexes such interrupts and delivers to the destination device(s). Having pci_msi_ignore_mask set in that scenario prevents (un)masking of MSI entries for devices behind the VMD bridge. Move the signaling of no entry masking into the MSI domain flags, as that allows setting it on a per-domain basis. Set it for the Xen MSI domain that uses the pIRQ chip, while leaving it unset for the rest of the cases. Remove pci_msi_ignore_mask at once, since it was only used by Xen code, and with Xen dropping usage the variable is unneeded. This fixes using devices behind a VMD bridge on Xen PV hardware domains. Albeit Devices behind a VMD bridge are not known to Xen, that doesn't mean Linux cannot use them. By inhibiting the usage of VMD_FEAT_CAN_BYPASS_MSI_REMAP and the removal of the pci_msi_ignore_mask bodge devices behind a VMD bridge do work fine when use from a Linux Xen hardware domain. That's the whole point of the series.

2025-03-21PCI: vmd: Disable MSI remapping bypass under XenRoger Pau Monne
MSI remapping bypass (directly configuring MSI entries for devices on the VMD bus) won't work under Xen, as Xen is not aware of devices in such bus, and hence cannot configure the entries using the pIRQ interface in the PV case, and in the PVH case traps won't be setup for MSI entries for such devices. Until Xen is aware of devices in the VMD bus prevent the VMD_FEAT_CAN_BYPASS_MSI_REMAP capability from being used when running as any kind of Xen guest. The MSI remapping bypass is an optional feature of VMD bridges, and hence when running under Xen it will be masked and devices will be forced to redirect its interrupts from the VMD bridge. That mode of operation must always be supported by VMD bridges and works when Xen is not aware of devices behind the VMD bridge.

2025-03-21x86/asm: Make asm export of __ref_stack_chk_guard unconditionalArd Biesheuvel
Clang does not tolerate the use of non-TLS symbols for the per-CPU stack protector very well, and to work around this limitation, the symbol passed via the -mstack-protector-guard-symbol= option is never defined in C code, but only in the linker script, and it is exported from an assembly file. This is necessary because Clang will fail to generate the correct %GS based references in a compilation unit that includes a non-TLS definition of the guard symbol being used to store the stack cookie. This problem is only triggered by symbol definitions, not by declarations, but nonetheless, the declaration in <asm/asm-prototypes.h> is conditional on __GENKSYMS__ being #define'd, so that only genksyms will observe it, but for ordinary compilation, it will be invisible. This is causing problems with the genksyms alternative gendwarfksyms, which does not #define __GENKSYMS__, does not observe the symbol declaration, and therefore lacks the information it needs to version it. Adding the #define creates problems in other places, so that is not a straight-forward solution. So take the easy way out, and drop the conditional on __GENKSYMS__, as this is not really needed to begin with.

2025-03-21xen/pci: Do not register devices with segments >= 0x10000Roger Pau Monne
The current hypercall interface for doing PCI device operations always uses a segment field that has a 16 bit width. However on Linux there are buses like VMD that hook up devices into the PCI hierarchy at segment >= 0x10000, after the maximum possible segment enumerated in ACPI. Attempting to register or manage those devices with Xen would result in errors at best, or overlaps with existing devices living on the truncated equivalent segment values. Note also that the VMD segment numbers are arbitrarily assigned by the OS, and hence there would need to be some negotiation between Xen and the OS to agree on how to enumerate VMD segments and devices behind them. Skip notifying Xen about those devices. Given how VMD bridges can multiplex interrupts on behalf of devices behind them there's no need for Xen to be aware of such devices for them to be usable by Linux.

2025-03-20io_uring: enable toggle of iowait usage when waiting on CQEsJens Axboe
By default, io_uring marks a waiting task as being in iowait, if it's sleeping waiting on events and there are pending requests. This isn't necessarily always useful, and may be confusing on non-storage setups where iowait isn't expected. It can also cause extra power usage, by preventing the CPU from entering lower sleep states. This adds a new enter flag, IORING_ENTER_NO_IOWAIT. If set, then io_uring will not account the sleeping task as being in iowait. If the kernel supports this feature, then it will be marked by having the IORING_FEAT_NO_IOWAIT feature flag set. As the kernel currently does not support separating the iowait accounting and CPU frequency boosting, the IORING_ENTER_NO_IOWAIT controls both of these at the same time. In the future, if those do end up being split, then it'd be possible to control them separately. However, it seems more likely that the kernel will decouple iowait and CPU frequency boosting anyway.

2025-03-20nvme-tcp: fix selinux denied when calling sock_sendmsgPeijie Shao
In a SELinux enabled kernel, socket_create() initializes the security label of the socket using the security label of the calling process, this typically works well. However, in a containerized environment like Kubernetes, problem arises when a privileged container(domain spc_t) connects to an NVMe target and mounts the NVMe as persistent storage for unprivileged containers(domain container_t). This is because the container_t domain cannot access resources labeled with spc_t, resulting in socket_sendmsg returning -EACCES. The solution is to use socket_create_kern() instead of socket_create(), which labels the socket context to kernel_t. Access control will then be handled by the VFS layer rather than the socket itself.

2025-03-20nvmet: pci-epf: Always configure BAR0 as 64-bitNiklas Cassel
NVMe PCIe Transport Specification 1.1, section 2.1.10, claims that the BAR0 type is Implementation Specific. However, in NVMe 1.1, the type is required to be 64-bit. Thus, to make our PCI EPF work on as many host systems as possible, always configure the BAR0 type to be 64-bit. In the rare case that the underlying PCI EPC does not support configuring BAR0 as 64-bit, the call to pci_epc_set_bar() will fail, and we will return a failure back to the user. This should not be a problem, as most PCI EPCs support configuring a BAR as 64-bit (and those EPCs with .only_64bit set to true in epc_features only support configuring the BAR as 64-bit).

2025-03-20nvme-multipath: Add visibility for queue-depth io-policyNilay Shroff
This patch helps add nvme native multipath visibility for queue-depth io-policy. It adds a new attribute file named "queue_depth" under namespace device path node which would print the number of active/ in-flight I/O requests currently queued for the given path. For instance, if we have a shared namespace accessible from two different controllers/paths then accessing head block node of the shared namespace would show the following output: $ ls -l /sys/block/nvme1n1/multipath/ nvme1c1n1 -> ../../../../../pci052e:78/052e:78:00.0/nvme/nvme1/nvme1c1n1 nvme1c3n1 -> ../../../../../pci058e:78/058e:78:00.0/nvme/nvme3/nvme1c3n1 In the above example, nvme1n1 is head gendisk node created for a shared namespace and the namespace is accessible from nvme1c1n1 and nvme1c3n1 paths. For queue-depth io-policy we can then refer the "queue_depth" attribute file created under each namespace path: $ cat /sys/block/nvme1n1/multipath/nvme1c1n1/queue_depth 518 $cat /sys/block/nvme1n1/multipath/nvme1c3n1/queue_depth 504 >From the above output, we can infer that I/O workload targeted at nvme1n1 uses two paths nvme1c1n1 and nvme1c3n1 and the current queue depth of each path is 518 and 504 respectively. Reading "queue_depth" file when configured io-policy is anything but queue-depth would show no output.

2025-03-20nvme-multipath: Add visibility for numa io-policyNilay Shroff
This patch helps add nvme native multipath visibility for numa io-policy. It adds a new attribute file named "numa_nodes" under namespace gendisk device path node which prints the list of numa nodes preferred by the given namespace path. The numa nodes value is comma delimited list of nodes or A-B range of nodes. For instance, if we have a shared namespace accessible from two different controllers/paths then accessing head node of the shared namespace would show the following output: $ ls -l /sys/block/nvme1n1/multipath/ nvme1c1n1 -> ../../../../../pci052e:78/052e:78:00.0/nvme/nvme1/nvme1c1n1 nvme1c3n1 -> ../../../../../pci058e:78/058e:78:00.0/nvme/nvme3/nvme1c3n1 In the above example, nvme1n1 is head gendisk node created for a shared namespace and this namespace is accessible from nvme1c1n1 and nvme1c3n1 paths. For numa io-policy we can then refer the "numa_nodes" attribute file created under each namespace path: $ cat /sys/block/nvme1n1/multipath/nvme1c1n1/numa_nodes 0-1 $ cat /sys/block/nvme1n1/multipath/nvme1c3n1/numa_nodes 2-3 >From the above output, we infer that I/O workload targeted at nvme1n1 and running on numa nodes 0 and 1 would prefer using path nvme1c1n1. Similarly, I/O workload running on numa nodes 2 and 3 would prefer using path nvme1c3n1. Reading "numa_nodes" file when configured io-policy is anything but numa would show no output.

This patch helps add nvme native multipath visibility for round-robin io-policy. It creates a "multipath" sysfs directory under head gendisk device node directory and then from "multipath" directory it adds a link to each namespace path device the head node refers. For instance, if we have a shared namespace accessible from two different controllers/paths then we create a soft link to each path device from head disk node as shown below: $ ls -l /sys/block/nvme1n1/multipath/ nvme1c1n1 -> ../../../../../pci052e:78/052e:78:00.0/nvme/nvme1/nvme1c1n1 nvme1c3n1 -> ../../../../../pci058e:78/058e:78:00.0/nvme/nvme3/nvme1c3n1 In the above example, nvme1n1 is head gendisk node created for a shared namespace and the namespace is accessible from nvme1c1n1 and nvme1c3n1 paths. For round-robin I/O policy, we could easily infer from the above output that I/O workload targeted to nvme1n1 would toggle across paths nvme1c1n1 and nvme1c3n1.
