Pull kvm updates from Paolo Bonzini: "Generic: - Use memdup_array_user() to harden against overflow. - Unconditionally advertise KVM_CAP_DEVICE_CTRL for all architectures. - Clean up Kconfigs that all KVM architectures were selecting - New functionality around "guest_memfd", a new userspace API that creates an anonymous file and returns a file descriptor that refers to it. guest_memfd files are bound to their owning virtual machine, cannot be mapped, read, or written by userspace, and cannot be resized. guest_memfd files do however support PUNCH_HOLE, which can be used to switch a memory area between guest_memfd and regular anonymous memory. - New ioctl KVM_SET_MEMORY_ATTRIBUTES allowing userspace to specify per-page attributes for a given page of guest memory; right now the only attribute is whether the guest expects to access memory via guest_memfd or not, which in Confidential SVMs backed by SEV-SNP, TDX or ARM64 pKVM is checked by firmware or hypervisor that guarantees confidentiality (AMD PSP, Intel TDX module, or EL2 in the case of pKVM). x86: - Support for "software-protected VMs" that can use the new guest_memfd and page attributes infrastructure. This is mostly useful for testing, since there is no pKVM-like infrastructure to provide a meaningfully reduced TCB. - Fix a relatively benign off-by-one error when splitting huge pages during CLEAR_DIRTY_LOG. - Fix a bug where KVM could incorrectly test-and-clear dirty bits in non-leaf TDP MMU SPTEs if a racing thread replaces a huge SPTE with a non-huge SPTE. - Use more generic lockdep assertions in paths that don't actually care about whether the caller is a reader or a writer. - let Xen guests opt out of having PV clock reported as "based on a stable TSC", because some of them don't expect the "TSC stable" bit (added to the pvclock ABI by KVM, but never set by Xen) to be set. - Revert a bogus, made-up nested SVM consistency check for TLB_CONTROL. - Advertise flush-by-ASID support for nSVM unconditionally, as KVM always flushes on nested transitions, i.e. always satisfies flush requests. This allows running bleeding edge versions of VMware Workstation on top of KVM. - Sanity check that the CPU supports flush-by-ASID when enabling SEV support. - On AMD machines with vNMI, always rely on hardware instead of intercepting IRET in some cases to detect unmasking of NMIs - Support for virtualizing Linear Address Masking (LAM) - Fix a variety of vPMU bugs where KVM fail to stop/reset counters and other state prior to refreshing the vPMU model. - Fix a double-overflow PMU bug by tracking emulated counter events using a dedicated field instead of snapshotting the "previous" counter. If the hardware PMC count triggers overflow that is recognized in the same VM-Exit that KVM manually bumps an event count, KVM would pend PMIs for both the hardware-triggered overflow and for KVM-triggered overflow. - Turn off KVM_WERROR by default for all configs so that it's not inadvertantly enabled by non-KVM developers, which can be problematic for subsystems that require no regressions for W=1 builds. - Advertise all of the host-supported CPUID bits that enumerate IA32_SPEC_CTRL "features". - Don't force a masterclock update when a vCPU synchronizes to the current TSC generation, as updating the masterclock can cause kvmclock's time to "jump" unexpectedly, e.g. when userspace hotplugs a pre-created vCPU. - Use RIP-relative address to read kvm_rebooting in the VM-Enter fault paths, partly as a super minor optimization, but mostly to make KVM play nice with position independent executable builds. - Guard KVM-on-HyperV's range-based TLB flush hooks with an #ifdef on CONFIG_HYPERV as a minor optimization, and to self-document the code. - Add CONFIG_KVM_HYPERV to allow disabling KVM support for HyperV "emulation" at build time. ARM64: - LPA2 support, adding 52bit IPA/PA capability for 4kB and 16kB base granule sizes. Branch shared with the arm64 tree. - Large Fine-Grained Trap rework, bringing some sanity to the feature, although there is more to come.

2024-01-17s390/vfio-ap: reset queues associated with adapter for queue unbound from driverTony Krowiak
When a queue is unbound from the vfio_ap device driver, if that queue is assigned to a guest's AP configuration, its associated adapter is removed because queues are defined to a guest via a matrix of adapters and domains; so, it is not possible to remove a single queue. If an adapter is removed from the guest's AP configuration, all associated queues must be reset to prevent leaking crypto data should any of them be assigned to a different guest or device driver. The one caveat is that if the queue is being removed because the adapter or domain has been removed from the host's AP configuration, then an attempt to reset the queue will fail with response code 01, AP-queue number not valid; so resetting these queues should be skipped.

2024-01-17s390/vfio-ap: reset queues filtered from the guest's AP configTony Krowiak
When filtering the adapters from the configuration profile for a guest to create or update a guest's AP configuration, if the APID of an adapter and the APQI of a domain identify a queue device that is not bound to the vfio_ap device driver, the APID of the adapter will be filtered because an individual APQN can not be filtered due to the fact the APQNs are assigned to an AP configuration as a matrix of APIDs and APQIs. Consequently, a guest will not have access to all of the queues associated with the filtered adapter. If the queues are subsequently made available again to the guest, they should re-appear in a reset state; so, let's make sure all queues associated with an adapter unplugged from the guest are reset. In order to identify the set of queues that need to be reset, let's allow a vfio_ap_queue object to be simultaneously stored in both a hashtable and a list: A hashtable used to store all of the queues assigned to a matrix mdev; and/or, a list used to store a subset of the queues that need to be reset. For example, when an adapter is hot unplugged from a guest, all guest queues associated with that adapter must be reset. Since that may be a subset of those assigned to the matrix mdev, they can be stored in a list that can be passed to the vfio_ap_mdev_reset_queues function.

2024-01-17s390/vfio-ap: let on_scan_complete() callback filter matrix and update ↵Tony Krowiak
guest's APCB When adapters and/or domains are added to the host's AP configuration, this may result in multiple queue devices getting created and probed by the vfio_ap device driver. For each queue device probed, the matrix of adapters and domains assigned to a matrix mdev will be filtered to update the guest's APCB. If any adapters or domains get added to or removed from the APCB, the guest's AP configuration will be dynamically updated (i.e., hot plug/unplug). To dynamically update the guest's configuration, its VCPUs must be taken out of SIE for the period of time it takes to make the update. This is disruptive to the guest's operation and if there are many queues probed due to a change in the host's AP configuration, this could be troublesome. The problem is exacerbated by the fact that the 'on_scan_complete' callback also filters the mdev's matrix and updates the guest's AP configuration. In order to reduce the potential amount of disruption to the guest that may result from a change to the host's AP configuration, let's bypass the filtering of the matrix and updating of the guest's AP configuration in the probe callback - if due to a host config change - and defer it until the 'on_scan_complete' callback is invoked after the AP bus finishes its device scan operation. This way the filtering and updating will be performed only once regardless of the number of queues added.

2024-01-17s390/vfio-ap: loop over the shadow APCB when filtering guest's AP configurationTony Krowiak
While filtering the mdev matrix, it doesn't make sense - and will have unexpected results - to filter an APID from the matrix if the APID or one of the associated APQIs is not in the host's AP configuration. There are two reasons for this: 1. An adapter or domain that is not in the host's AP configuration can be assigned to the matrix; this is known as over-provisioning. Queue devices, however, are only created for adapters and domains in the host's AP configuration, so there will be no queues associated with an over-provisioned adapter or domain to filter. 2. The adapter or domain may have been externally removed from the host's configuration via an SE or HMC attached to a DPM enabled LPAR. In this case, the vfio_ap device driver would have been notified by the AP bus via the on_config_changed callback and the adapter or domain would have already been filtered. Since the matrix_mdev->shadow_apcb.apm and matrix_mdev->shadow_apcb.aqm are copied from the mdev matrix sans the APIDs and APQIs not in the host's AP configuration, let's loop over those bitmaps instead of those assigned to the matrix.

2024-01-17s390/vfio-ap: always filter entire AP matrixTony Krowiak
The vfio_ap_mdev_filter_matrix function is called whenever a new adapter or domain is assigned to the mdev. The purpose of the function is to update the guest's AP configuration by filtering the matrix of adapters and domains assigned to the mdev. When an adapter or domain is assigned, only the APQNs associated with the APID of the new adapter or APQI of the new domain are inspected. If an APQN does not reference a queue device bound to the vfio_ap device driver, then it's APID will be filtered from the mdev's matrix when updating the guest's AP configuration. Inspecting only the APID of the new adapter or APQI of the new domain will result in passing AP queues through to a guest that are not bound to the vfio_ap device driver under certain circumstances. Consider the following: guest's AP configuration (all also assigned to the mdev's matrix): 14.0004 14.0005 14.0006 16.0004 16.0005 16.0006 unassign domain 4 unbind queue 16.0005 assign domain 4 When domain 4 is re-assigned, since only domain 4 will be inspected, the APQNs that will be examined will be: 14.0004 16.0004 Since both of those APQNs reference queue devices that are bound to the vfio_ap device driver, nothing will get filtered from the mdev's matrix when updating the guest's AP configuration. Consequently, queue 16.0005 will get passed through despite not being bound to the driver. This violates the linux device model requirement that a guest shall only be given access to devices bound to the device driver facilitating their pass-through. To resolve this problem, every adapter and domain assigned to the mdev will be inspected when filtering the mdev's matrix.

2024-01-17net: stmmac: Prevent DSA tags from breaking COERomain Gantois
Some DSA tagging protocols change the EtherType field in the MAC header e.g. DSA_TAG_PROTO_(DSA/EDSA/BRCM/MTK/RTL4C_A/SJA1105). On TX these tagged frames are ignored by the checksum offload engine and IP header checker of some stmmac cores. On RX, the stmmac driver wrongly assumes that checksums have been computed for these tagged packets, and sets CHECKSUM_UNNECESSARY. Add an additional check in the stmmac TX and RX hotpaths so that COE is deactivated for packets with ethertypes that will not trigger the COE and IP header checks.

This reverts commits 1979a2807547 ("gpiolib: replace the GPIO device mutex with a read-write semaphore") and 65a828bab158 ("gpiolib: use a mutex to protect the list of GPIO devices"). Unfortunately the legacy GPIO API that's still used in older code has to translate numbers from the global GPIO numberspace to descriptors. This results in a GPIO device lookup in every call to legacy functions. Some of those functions - like gpio_set/get_value() - can be called from atomic context so taking a sleeping lock that is an RW semaphore results in an error. We'll probably have to protect this list with SRCU.
