git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux Pull selinux updates from Paul Moore: - Add additional SELinux access controls for kernel file reads/loads The SELinux kernel file read/load access controls were never updated beyond the initial kernel module support, this pull request adds support for firmware, kexec, policies, and x.509 certificates. - Add support for wildcards in network interface names There are a number of userspace tools which auto-generate network interface names using some pattern of <XXXX>-<NN> where <XXXX> is a fixed string, e.g. "podman", and <NN> is a increasing counter. Supporting wildcards in the SELinux policy for network interfaces simplifies the policy associted with these interfaces. - Fix a potential problem in the kernel read file SELinux code SELinux should always check the file label in the security_kernel_read_file() LSM hook, regardless of if the file is being read in chunks. Unfortunately, the existing code only considered the file label on the first chunk; this pull request fixes this problem. There is more detail in the individual commit, but thankfully the existing code didn't expose a bug due to multi-stage reads only taking place in one driver, and that driver loading a file type that isn't targeted by the SELinux policy. - Fix the subshell error handling in the example policy loader Minor fix to SELinux example policy loader in scripts/selinux due to an undesired interaction with subshells and errexit. * tag 'selinux-pr-20250323' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: selinux: get netif_wildcard policycap from policy instead of cache selinux: support wildcard network interface names selinux: Chain up tool resolving errors in install_policy.sh selinux: add permission checks for loading other kinds of kernel files selinux: always check the file label in selinux_kernel_read_file() selinux: fix spelling error

git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm Pull lsm updates from Paul Moore: - Various minor updates to the LSM Rust bindings Changes include marking trivial Rust bindings as inlines and comment tweaks to better reflect the LSM hooks. - Add LSM/SELinux access controls to io_uring_allowed() Similar to the io_uring_disabled sysctl, add a LSM hook to io_uring_allowed() to enable LSMs a simple way to enforce security policy on the use of io_uring. This pull request includes SELinux support for this new control using the io_uring/allowed permission. - Remove an unused parameter from the security_perf_event_open() hook The perf_event_attr struct parameter was not used by any currently supported LSMs, remove it from the hook. - Add an explicit MAINTAINERS entry for the credentials code We've seen problems in the past where patches to the credentials code sent by non-maintainers would often languish on the lists for multiple months as there was no one explicitly tasked with the responsibility of reviewing and/or merging credentials related code. Considering that most of the code under security/ has a vested interest in ensuring that the credentials code is well maintained, I'm volunteering to look after the credentials code and Serge Hallyn has also volunteered to step up as an official reviewer.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull power management updates from Rafael Wysocki: "These are dominated by cpufreq updates which in turn are dominated by updates related to boost support in the core and drivers and amd-pstate driver optimizations. Apart from the above, there are some cpuidle updates including a rework of the most recent idle intervals handling in the venerable menu governor that leads to significant improvements in some performance benchmarks, as the governor is now more likely to predict a shorter idle duration in some cases, and there are updates of the core device power management code, mostly related to system suspend and resume, that should help to avoid potential issues arising when the drivers of devices depending on one another want to use different optimizations. There is also a usual collection of assorted fixes and cleanups, including removal of some unused code. Specifics: - Manage sysfs attributes and boost frequencies efficiently from cpufreq core to reduce boilerplate code in drivers (Viresh Kumar) - Minor cleanups to cpufreq drivers (Aaron Kling, Benjamin Schneider, Dhananjay Ugwekar, Imran Shaik, zuoqian) - Migrate some cpufreq drivers to using for_each_present_cpu() (Jacky Bai) - cpufreq-qcom-hw DT binding fixes (Krzysztof Kozlowski) - Use str_enable_disable() helper in cpufreq_online() (Lifeng Zheng) - Optimize the amd-pstate driver to avoid cases where call paths end up calling the same writes multiple times and needlessly caching variables through code reorganization, locking overhaul and tracing adjustments (Mario Limonciello, Dhananjay Ugwekar) - Make it possible to avoid enabling capacity-aware scheduling (CAS) in the intel_pstate driver and relocate a check for out-of-band (OOB) platform handling in it to make it detect OOB before checking HWP availability (Rafael Wysocki) - Fix dbs_update() to avoid inadvertent conversions of negative integer values to unsigned int which causes CPU frequency selection to be inaccurate in some cases when the "conservative" cpufreq governor is in use (Jie Zhan) - Update the handling of the most recent idle intervals in the menu cpuidle governor to prevent useful information from being discarded by it in some cases and improve the prediction accuracy (Rafael Wysocki) - Make it possible to tell the intel_idle driver to ignore its built-in table of idle states for the given processor, clean up the handling of auto-demotion disabling on Baytrail and Cherrytrail chips in it, and update its MAINTAINERS entry (David Arcari, Artem Bityutskiy, Rafael Wysocki) - Make some cpuidle drivers use for_each_present_cpu() instead of for_each_possible_cpu() during initialization to avoid issues occurring when nosmp or maxcpus=0 are used (Jacky Bai) - Clean up the Energy Model handling code somewhat (Rafael Wysocki) - Use kfree_rcu() to simplify the handling of runtime Energy Model updates (Li RongQing) - Add an entry for the Energy Model framework to MAINTAINERS as properly maintained (Lukasz Luba) - Address RCU-related sparse warnings in the Energy Model code (Rafael Wysocki) - Remove ENERGY_MODEL dependency on SMP and allow it to be selected when DEVFREQ is set without CPUFREQ so it can be used on a wider range of systems (Jeson Gao) - Unify error handling during runtime suspend and runtime resume in the core to help drivers to implement more consistent runtime PM error handling (Rafael Wysocki) - Drop a redundant check from pm_runtime_force_resume() and rearrange documentation related to __pm_runtime_disable() (Rafael Wysocki) - Rework the handling of the "smart suspend" driver flag in the PM core to avoid issues hat may occur when drivers using it depend on some other drivers and clean up the related PM core code (Rafael Wysocki, Colin Ian King) - Fix the handling of devices with the power.direct_complete flag set if device_suspend() returns an error for at least one device to avoid situations in which some of them may not be resumed (Rafael Wysocki) - Use mutex_trylock() in hibernate_compressor_param_set() to avoid a possible deadlock that may occur if the "compressor" hibernation module parameter is accessed during the registration of a new ieee80211 device (Lizhi Xu) - Suppress sleeping parent warning in device_pm_add() in the case when new children are added under a device with the power.direct_complete set after it has been processed by device_resume() (Xu Yang) - Remove needless return in three void functions related to system wakeup (Zijun Hu) - Replace deprecated kmap_atomic() with kmap_local_page() in the hibernation core code (David Reaver) - Remove unused helper functions related to system sleep (David Alan Gilbert) - Clean up s2idle_enter() so it does not lock and unlock CPU offline in vain and update comments in it (Ulf Hansson) - Clean up broken white space in dpm_wait_for_children() (Geert Uytterhoeven) - Update the cpupower utility to fix lib version-ing in it and memory leaks in error legs, remove hard-coded values, and implement CPU physical core querying (Thomas Renninger, John B.

Andy Shevchenko says: ==================== net: usb: asix: ax88772: Fix potential string cut The agreement and also PHY_MAX_ADDR limit suggest that the PHY address can't occupy more than two hex digits. In some cases GCC complains about potential string cut. In course of fixing this, introduce the PHY_ID_SIZE predefined constant to make it easier for the users to know the bare minimum for the buffer that holds PHY ID string (patch 1).

2025-03-25net: usb: asix: ax88772: Increase phy_name sizeAndy Shevchenko
GCC compiler (Debian 14.2.0-17) is not happy about printing into a too short buffer (when build with `make W=1`): drivers/net/usb/ax88172a.c:311:9: note: ‘snprintf’ output between 4 and 66 bytes into a destination of size 20 Indeed, the buffer size is chosen based on some assumptions, while in general the assigned name might not fit. Increase the buffer size to cover the minimum required one. With that, change snprintf() to use sizeof() instead of the hard coded value. While at it, make sure that the PHY address is not bigger than the allowed maximum.

2025-03-25net: phy: Introduce PHY_ID_SIZE — minimum size for PHY ID stringAndy Shevchenko
The PHY_ID_FMT defines the format specifier "%s:%02x" to form the PHY ID string, where the maximum of the first part is defined in MII_BUS_ID_SIZE, including NUL terminator, and the second part is implied to be 3 as the maximum address is limited to 32, meaning that 2 hex digits is more than enough, plus ':' (colon) delimiter. However, some drivers, which are using PHY_ID_FMT, customise buffer size and do that incorrectly. Introduce a new constant PHY_ID_SIZE that makes the minimum required size explicit, so drivers are encouraged to use it.

Pull kvm updates from Paolo Bonzini: "ARM: - Nested virtualization support for VGICv3, giving the nested hypervisor control of the VGIC hardware when running an L2 VM - Removal of 'late' nested virtualization feature register masking, making the supported feature set directly visible to userspace - Support for emulating FEAT_PMUv3 on Apple silicon, taking advantage of an IMPLEMENTATION DEFINED trap that covers all PMUv3 registers - Paravirtual interface for discovering the set of CPU implementations where a VM may run, addressing a longstanding issue of guest CPU errata awareness in big-little systems and cross-implementation VM migration - Userspace control of the registers responsible for identifying a particular CPU implementation (MIDR_EL1, REVIDR_EL1, AIDR_EL1), allowing VMs to be migrated cross-implementation - pKVM updates, including support for tracking stage-2 page table allocations in the protected hypervisor in the 'SecPageTable' stat - Fixes to vPMU, ensuring that userspace updates to the vPMU after KVM_RUN are reflected into the backing perf events LoongArch: - Remove unnecessary header include path - Assume constant PGD during VM context switch - Add perf events support for guest VM RISC-V: - Disable the kernel perf counter during configure - KVM selftests improvements for PMU - Fix warning at the time of KVM module removal x86: - Add support for aging of SPTEs without holding mmu_lock. Not taking mmu_lock allows multiple aging actions to run in parallel, and more importantly avoids stalling vCPUs. This includes an implementation of per-rmap-entry locking; aging the gfn is done with only a per-rmap single-bin spinlock taken, whereas locking an rmap for write requires taking both the per-rmap spinlock and the mmu_lock. Note that this decreases slightly the accuracy of accessed-page information, because changes to the SPTE outside aging might not use atomic operations even if they could race against a clear of the Accessed bit. This is deliberate because KVM and mm/ tolerate false positives/negatives for accessed information, and testing has shown that reducing the latency of aging is far more beneficial to overall system performance than providing "perfect" young/old information. - Defer runtime CPUID updates until KVM emulates a CPUID instruction, to coalesce updates when multiple pieces of vCPU state are changing, e.g. as part of a nested transition - Fix a variety of nested emulation bugs, and add VMX support for synthesizing nested VM-Exit on interception (instead of injecting #UD into L2) - Drop "support" for async page faults for protected guests that do not set SEND_ALWAYS (i.e. that only want async page faults at CPL3) - Bring a bit of sanity to x86's VM teardown code, which has accumulated a lot of cruft over the years. Particularly, destroy vCPUs before the MMU, despite the latter being a VM-wide operation - Add common secure TSC infrastructure for use within SNP and in the future TDX - Block KVM_CAP_SYNC_REGS if guest state is protected. It does not make sense to use the capability if the relevant registers are not available for reading or writing - Don't take kvm->lock when iterating over vCPUs in the suspend notifier to fix a largely theoretical deadlock - Use the vCPU's actual Xen PV clock information when starting the Xen timer, as the cached state in arch.hv_clock can be stale/bogus - Fix a bug where KVM could bleed PVCLOCK_GUEST_STOPPED across different PV clocks; restrict PVCLOCK_GUEST_STOPPED to kvmclock, as KVM's suspend notifier only accounts for kvmclock, and there's no evidence that the flag is actually supported by Xen guests - Clean up the per-vCPU "cache" of its reference pvclock, and instead only track the vCPU's TSC scaling (multipler+shift) metadata (which is moderately expensive to compute, and rarely changes for modern setups) - Don't write to the Xen hypercall page on MSR writes that are initiated by the host (userspace or KVM) to fix a class of bugs where KVM can write to guest memory at unexpected times, e.g. during vCPU creation if userspace has set the Xen hypercall MSR index to collide with an MSR that KVM emulates - Restrict the Xen hypercall MSR index to the unofficial synthetic range to reduce the set of possible collisions with MSRs that are emulated by KVM (collisions can still happen as KVM emulates Hyper-V MSRs, which also reside in the synthetic range) - Clean up and optimize KVM's handling of Xen MSR writes and xen_hvm_config - Update Xen TSC leaves during CPUID emulation instead of modifying the CPUID entries when updating PV clocks; there is no guarantee PV clocks will be updated between TSC frequency changes and CPUID emulation, and guest reads of the TSC leaves should be rare, i.e. are not a hot path x86 (Intel): - Fix a bug where KVM unnecessarily reads XFD_ERR from hardware and thus modifies the vCPU's XFD_ERR on a #NM due to CR0.TS=1 - Pass XFD_ERR as the payload when injecting #NM, as a preparatory step for upcoming FRED virtualization support - Decouple the EPT entry RWX protection bit macros from the EPT Violation bits, both as a general cleanup and in anticipation of adding support for emulating Mode-Based Execution Control (MBEC) - Reject KVM_RUN if userspace manages to gain control and stuff invalid guest state while KVM is in the middle of emulating nested VM-Enter - Add a macro to handle KVM's sanity checks on entry/exit VMCS control pairs in anticipation of adding sanity checks for secondary exit controls (the primary field is out of bits) x86 (AMD): - Ensure the PSP driver is initialized when both the PSP and KVM modules are built-in (the initcall framework doesn't handle dependencies) - Use long-term pins when registering encrypted memory regions, so that the pages are migrated out of MIGRATE_CMA/ZONE_MOVABLE and don't lead to excessive fragmentation - Add macros and helpers for setting GHCB return/error codes - Add support for Idle HLT interception, which elides interception if the vCPU has a pending, unmasked virtual IRQ when HLT is executed - Fix a bug in INVPCID emulation where KVM fails to check for a non-canonical address - Don't attempt VMRUN for SEV-ES+ guests if the vCPU's VMSA is invalid, e.g. because the vCPU was "destroyed" via SNP's AP Creation hypercall - Reject SNP AP Creation if the requested SEV features for the vCPU don't match the VM's configured set of features Selftests: - Fix again the Intel PMU counters test; add a data load and do CLFLUSH{OPT} on the data instead of executing code. The theory is that modern Intel CPUs have learned new code prefetching tricks that bypass the PMU counters - Fix a flaw in the Intel PMU counters test where it asserts that an event is counting correctly without actually knowing what the event counts on the underlying hardware - Fix a variety of flaws, bugs, and false failures/passes dirty_log_test, and improve its coverage by collecting all dirty entries on each iteration - Fix a few minor bugs related to handling of stats FDs - Add infrastructure to make vCPU and VM stats FDs available to tests by default (open the FDs during VM/vCPU creation) - Relax an assertion on the number of HLT exits in the xAPIC IPI test when running on a CPU that supports AMD's Idle HLT (which elides interception of HLT if a virtual IRQ is pending and unmasked)" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (216 commits) RISC-V: KVM: Optimize comments in kvm_riscv_vcpu_isa_disable_allowed RISC-V: KVM: Teardown riscv specific bits after kvm_exit LoongArch: KVM: Register perf callbacks for guest LoongArch: KVM: Implement arch-specific functions for guest perf LoongArch: KVM: Add stub for kvm_arch_vcpu_preempted_in_kernel() LoongArch: KVM: Remove PGD saving during VM context switch LoongArch: KVM: Remove unnecessary header include path KVM: arm64: Tear down vGIC on failed vCPU creation KVM: arm64: PMU: Reload when resetting KVM: arm64: PMU: Reload when user modifies registers KVM: arm64: PMU: Fix SET_ONE_REG for vPMC regs KVM: arm64: PMU: Assume PMU presence in pmu-emul.c KVM: arm64: PMU: Set raw values from user to PM{C,I}NTEN{SET,CLR}, PMOVS{SET,CLR} KVM: arm64: Create each pKVM hyp vcpu after its corresponding host vcpu KVM: arm64: Factor out pKVM hyp vcpu creation to separate function KVM: arm64: Initialize HCRX_EL2 traps in pKVM KVM: arm64: Factor out setting HCRX_EL2 traps into separate function KVM: x86: block KVM_CAP_SYNC_REGS if guest state is protected KVM: x86: Add infrastructure for secure TSC KVM: x86: Push down setting vcpu.arch.user_set_tsc ...

When MPOA_cache_impos_rcvd() receives the msg, it can trigger Null Pointer Dereference Vulnerability if both entry and holding_time are NULL. Because there is only for the situation where entry is NULL and holding_time exists, it can be passed when both entry and holding_time are NULL.

2025-03-25net: tn40xx: add pci-id of the aqr105-based Tehuti TN4010 cardsHans-Frieder Vogt
Add the PCI-ID of the AQR105-based Tehuti TN4010 cards to allow loading of the tn40xx driver on these cards.

2025-03-25net: tn40xx: prepare tn40xx driver to find phy of the TN9510 cardHans-Frieder Vogt
Prepare the tn40xx driver to load for Tehuti TN9510 cards, which require bit 3 in the register TN40_REG_MDIO_CMD_STAT to be set. The function of bit 3 is unclear, but may have something to do with the length of the preamble in the MDIO communication. If bit 3 is not set, the PHY will not be found when performing a scan for PHYs. Use the available tn40_mdio_set_speed function which includes setting bit 3. Just move the function to before the devm_mdio_register function, which scans the mdio bus for PHYs.

This patch makes functions that were provided for aqr107 applicable to aqr105, or replaces generic functions with specific ones.

2025-03-25gve: add XDP DROP and PASS support for DQJoshua Washington
This patch adds support for running XDP programs on DQ, along with rudimentary processing for XDP_DROP and XDP_PASS. These actions require very limited driver functionality when it comes to processing an XDP buffer, so currently if the XDP action is not XDP_PASS, the packet is dropped and stats are updated.

2025-03-25gve: update XDP allocation path support RX buffer postingJoshua Washington
In order to support installing an XDP program on DQ, RX buffers need to be reposted using 4K buffers, which is larger than the default packet buffer size of 2K. This is needed to accommodate the extra head and tail that accompanies the data portion of an XDP buffer. Continuing to use 2K buffers would mean that the packet buffer size for the NIC would have to be restricted to 2048 - 320 - 256 = 1472B. However, this is problematic for two reasons: first, 1472 is not a packet buffer size accepted by GVE; second, at least 1474B of buffer space is needed to accommodate an MTU of 1460, which is the default on GCP. As such, we allocate 4K buffers, and post a 2K section of those 4K buffers (offset relative to the XDP headroom) to the NIC for DMA to avoid a potential extra copy. Because the GQ-QPL datapath requires copies regardless, this change was not needed to support XDP in that case. To capture this subtlety, a new field, packet_buffer_truesize, has been added to the rx ring struct to represent size of the allocated buffer, while packet_buffer_size has been left to represent the portion of the buffer posted to the NIC.

The data_buffer_size_dqo field in gve_priv and the packet_buffer_size field in gve_rx_ring theoretically have the same meaning, but they are defined in two different places and used in two separate contexts. There is no good reason for this, so this change merges those fields into the packet_buffer_size field in the RX ring. This change also introduces a packet_buffer_size field to struct gve_rx_queue_config to account for cases where queues are not allocated, such as when the interface is down.

Commit ebdfae0d377b ("gve: adopt page pool for DQ RDA mode") introduced a buf_size field to the gve_rx_slot_page_info struct, which can be used in the datapath to take the place of the packet_buffer_size field, as it will already be hot in the cache due to its extensive use. Using the buf_size field in the datapath frees up the packet_buffer_size field in the GQ-specific RX cacheline to be generalized for GQ and DQ (in the next patch), as there is currently no common packet buffer size field between the two queue formats.

2025-03-25gve: introduce config-based allocation for XDPJoshua Washington
An earlier patch series[1] introduced RX/TX ring allocation configuration structs which contained metadata used to allocate and configure new RX and TX rings. This led to a much cleaner and safer allocation pattern wherein queue resources were not deallocated until new queue resources were successfully allocated. Migrate the XDP allocation path to use the same pattern to allow for the existence of a single allocation path instead of relying on XDP-specific allocation methods. These extra allocation methods result in the duplication of many existing behaviors while being prone to error when configuration changes unrelated to XDP occur.

Some controllers seems to generate HCI_EV_LE_DIRECT_ADV_REPORT even when scan_filter is not set to 0x02 or 0x03, which indicates that local privacy is enabled, causing them to be ignored thus breaking auto-connect logic: < HCI Command: LE Set Scan Parameters (0x08|0x000b) plen 7 Type: Passive (0x00) Interval: 60.000 msec (0x0060) Window: 30.000 msec (0x0030) Own address type: Public (0x00) Filter policy: Ignore not in accept list (0x01) ... > HCI Event: LE Meta Event (0x3e) plen 18 LE Direct Advertising Report (0x0b) Num reports: 1 Event type: Connectable directed - ADV_DIRECT_IND (0x01) Address type: Random (0x01) Address: XX:XX:XX:XX:XX:XX (Static) Direct address type: Random (0x01) Direct address: XX:XX:XX:XX:XX:XX (Non-Resolvable) RSSI: -54 dBm (0xca) So this attempts to mitigate the above problem by skipping checking of direct_addr if local privacy is not enabled.

2025-03-25Bluetooth: btnxpuart: Fix kernel panic during FW releaseNeeraj Sanjay Kale
This fixes a kernel panic seen during release FW in a stress test scenario where WLAN and BT FW download occurs simultaneously, and due to a HW bug, chip sends out only 1 bootloader signatures. When driver receives the bootloader signature, it enters FW download mode, but since no consequtive bootloader signatures seen, FW file is not requested. After 60 seconds, when FW download times out, release_firmware causes a kernel panic.

2025-03-25Bluetooth: btnxpuart: Handle bootloader error during cmd5 and cmd7Neeraj Sanjay Kale
This handles the scenario where the driver receives an error code after sending cmd5 or cmd7 in the bootloader signature during FW download. The bootloader error code is handled by the driver and FW offset is corrected accordingly, and the cmd5 or cmd7 is re-sent to the controller in case of CRC error.
