More eventfs fixes and a seq_buf fix for 6.8:
- Hard-code the inodes for eventfs to the same number for files, and the same number for directories. - Have getdent() not create dentries/inodes in iterate_shared() as now it has hard-coded inode numbers - Use kcalloc() instead of kzalloc() on a list of elements - Fix seq_buf warning and make static work properly. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZak5GxQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qvZYAP0ZO4YN9fKnl6Cw1GNCwPtMO13dEg9D mIvwftxX8DuaegD/fQFY9gBc+ZMSCbiWVJBAyfO57NPvHk4S3slwPVuL9gA= =iKJI -----END PGP SIGNATURE----- Merge tag 'eventfs-v6.8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull eventfs updates from Steven Rostedt: - Remove "lookup" parameter of create_dir_dentry() and create_file_dentry(). These functions were called by lookup and the readdir logic, where readdir needed it to up the ref count of the dentry but the lookup did not. A "lookup" parameter was passed in to tell it what to do, but this complicated the code. It is better to just always up the ref count and require the caller to decrement it, even for lookup. - Modify the .iterate_shared callback to not use the dcache_readdir() logic and just handle what gets displayed by that one function. This removes the need for eventfs to hijack the file->private_data from the dcache_readdir() "cursor" pointer, and makes the code a bit more sane - Use the root and instance inodes for default ownership. Instead of walking the dentry tree and updating each dentry gid, use the getattr(), setattr() and permission() callbacks to set the ownership and permissions using the root or instance as the default - Some other optimizations with the eventfs iterate_shared logic - Hard-code the inodes for eventfs to the same number for files, and the same number for directories - Have getdent() not create dentries/inodes in iterate_shared() as now it has hard-coded inode numbers - Use kcalloc() instead of kzalloc() on a list of elements - Fix seq_buf warning and make static work properly. * tag 'eventfs-v6.8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: seq_buf: Make DECLARE_SEQ_BUF() usable eventfs: Use kcalloc() instead of kzalloc() eventfs: Do not create dentries nor inodes in iterate_shared eventfs: Have the inodes all for files and directories all be the same eventfs: Shortcut eventfs_iterate() by skipping entries already read eventfs: Read ei->entries before ei->children in eventfs_iterate() eventfs: Do ctx->pos update for all iterations in eventfs_iterate() eventfs: Have eventfs_iterate() stop immediately if ei->is_freed is set tracefs/eventfs: Use root and instance inodes as default ownership eventfs: Stop using dcache_readdir() for getdents() eventfs: Remove "lookup" parameter from create_dir/file_dentry() |

tracing updates for 6.8:
- Allow kernel trace instance creation to specify what events are created Inside the kernel, a subsystem may create a tracing instance that it can use to send events to user space. This sub-system may not care about the thousands of events that exist in eventfs. Allow the sub-system to specify what sub-systems of events it cares about, and only those events are exposed to this instance. - Allow the ring buffer to be broken up into bigger sub-buffers than just the architecture page size. A new tracefs file called "buffer_subbuf_size_kb" is created. The user can now specify a minimum size the sub-buffer may be in kilobytes. Note, that the implementation currently make the sub-buffer size a power of 2 pages (1, 2, 4, 8, 16, ...) but the user only writes in kilobyte size, and the sub-buffer will be updated to the next size that it will can accommodate it. If the user writes in 10, it will change the size to be 4 pages on x86 (16K), as that is the next available size that can hold 10K pages. - Update the debug output when a corrupt time is detected in the ring buffer. If the ring buffer detects inconsistent timestamps, there's a debug config options that will dump the contents of the meta data of the sub-buffer that is used for debugging. Add some more information to this dump that helps with debugging. - Add more timestamp debugging checks (only triggers when the config is enabled) - Increase the trace_seq iterator to 2 page sizes. - Allow strings written into tracefs_marker to be larger. Up to just under 2 page sizes (based on what trace_seq can hold). - Increase the trace_maker_raw write to be as big as a sub-buffer can hold. - Remove 32 bit time stamp logic, now that the rb_time_cmpxchg() has been removed. - More selftests were added. - Some code clean ups as well. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZZ8p3BQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6ql2GAQDZg/zlFEiJHyTfWbCIE8pA3T5xbzKo 26TNxIZAxJJZpQEAvGFU5Smy14pG6soEoVMp8B6ZOANbqU8VVamhOL+r+Qw= =0OYG -----END PGP SIGNATURE----- Merge tag 'trace-v6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing updates from Steven Rostedt: - Allow kernel trace instance creation to specify what events are created Inside the kernel, a subsystem may create a tracing instance that it can use to send events to user space.

This does not include the actual KVM-side support which will come from the KVM folks. The TDX host interactions with kexec also needs to be ironed out before this is ready for prime time, so this code is currently Kconfig'd off when kexec is on. The majority of the code here is the kernel telling the TDX module which memory to protect and handing some additional memory over to it to use to store TDX module metadata. That sounds pretty simple, but the TDX architecture is rather flexible and it takes quite a bit of back-and-forth to say, "just protect all memory, please." There is also some code tacked on near the end of the series to handle a hardware erratum. The erratum can make software bugs such as a kernel write to TDX-protected memory cause a machine check and masquerade as a real hardware failure. The erratum handling watches out for these and tries to provide nicer user errors" * tag 'x86_tdx_for_6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (21 commits) x86/virt/tdx: Make TDX host depend on X86_MCE x86/virt/tdx: Disable TDX host support when kexec is enabled Documentation/x86: Add documentation for TDX host support x86/mce: Differentiate real hardware #MCs from TDX erratum ones x86/cpu: Detect TDX partial write machine check erratum x86/virt/tdx: Handle TDX interaction with sleep and hibernation x86/virt/tdx: Initialize all TDMRs x86/virt/tdx: Configure global KeyID on all packages x86/virt/tdx: Configure TDX module with the TDMRs and global KeyID x86/virt/tdx: Designate reserved areas for all TDMRs x86/virt/tdx: Allocate and set up PAMTs for TDMRs x86/virt/tdx: Fill out TDMRs to cover all TDX memory regions x86/virt/tdx: Add placeholder to construct TDMRs to cover all TDX memory regions x86/virt/tdx: Get module global metadata for module initialization x86/virt/tdx: Use all system memory when initializing TDX module as TDX memory x86/virt/tdx: Add skeleton to enable TDX on demand x86/virt/tdx: Add SEAMCALL error printing for module initialization x86/virt/tdx: Handle SEAMCALL no entropy error in common code x86/virt/tdx: Make INTEL_TDX_HOST depend on X86_X2APIC x86/virt/tdx: Define TDX supported page sizes as macros ... |

Driver core changes for 6.8-rc1
Here are the set of driver core and kernfs changes for 6.8-rc1. Nothing
major in here this release cycle, just lots of small cleanups and some
tweaks on kernfs that in the very end, got reverted and will come back
in a safer way next release cycle.
Included in here are:
- more driver core 'const' cleanups and fixes
- fw_devlink=rpm is now the default behavior
- kernfs tiny changes to remove some string functions
- cpu handling in the driver core is updated to work better on many
systems that add topologies and cpus after booting
- other minor changes and cleanups
All of the cpu handling patches have been acked by the respective
maintainers and are coming in here in one series. Everything has been
in linux-next for a while with no reported issues.

seq_buf: Make DECLARE_SEQ_BUF() usable
Using the address operator on the array doesn't work:
./include/linux/seq_buf.h:27:27: error: initialization of ‘char *’
from incompatible pointer type ‘char (*)[128]’
[-Werror=incompatible-pointer-types]
27 | .buffer = &__ ## NAME ## _buffer, \
| ^
Apart from fixing that, we can improve DECLARE_SEQ_BUF() by using a
compound literal to define the buffer array without attaching a name
to it. This makes the macro a single statement, allowing constructs
such as:
static DECLARE_SEQ_BUF(my_seq_buf, MYSB_SIZE);
to work as intended.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Reserve ECAM so we don't assign it to PCI BARs; this works around
bugs where BIOS included ECAM in a PNP0A03 host bridge window,
didn't reserve it via a PNP0C02 motherboard device, and didn't
allocate space for SR-IOV VF BARs (Bjorn Helgaas)
- Add MMCONFIG/ECAM debug logging (Bjorn Helgaas)
- Rename 'MMCONFIG' to 'ECAM' to match spec usage (Bjorn Helgaas)
- Log device type (Root Port, Switch Port, etc) during enumeration
(Bjorn Helgaas)
- Log bridges before downstream devices so the dmesg order is more
logical (Bjorn Helgaas)
- Log resource names (BAR 0, VF BAR 0, bridge window, etc)
consistently instead of a mix of names and "reg 0x10" (Puranjay
Mohan, Bjorn Helgaas)
- Fix 64GT/s effective data rate calculation to use 1b/1b encoding
rather than the 8b/10b or 128b/130b used by lower rates (Ilpo
Järvinen)
- Use PCI_HEADER_TYPE_* instead of literals in x86, powerpc, SCSI
lpfc (Ilpo Järvinen)
- Clean up open-coded PCIBIOS return code mangling (Ilpo Järvinen)
Resource management:
- Restructure pci_dev_for_each_resource() to avoid computing the
address of an out-of-bounds array element (the bounds check was
performed later so the element was never actually *read*, but it's
nicer to avoid even computing an out-of-bounds address) (Andy
Shevchenko)
Driver binding:
- Convert pci-host-common.c platform .remove() callback to
.remove_new() returning 'void' since it's not useful to return
error codes here (Uwe Kleine-König)
- Convert exynos, keystone, kirin from .remove() to .remove_new(),
which returns void instead of int (Uwe Kleine-König)
- Drop unused struct pci_driver.node member (Mathias Krause)
Virtualization:
- Add ACS quirk for more Zhaoxin Root Ports (LeoLiuoc)
Error handling:
- Log AER errors as "Correctable" (not "Corrected") or
"Uncorrectable" to match spec terminology (Bjorn Helgaas)
- Decode Requester ID when no error info found instead of printing
the raw hex value (Bjorn Helgaas)
Endpoint framework:
- Use a unique test pattern for each BAR in the pci_endpoint_test to
make it easier to debug address translation issues (Niklas Cassel)
Broadcom STB PCIe controller driver:
- Add DT property "brcm,clkreq-mode" and driver support for different
CLKREQ# modes to make ASPM L1.x states possible (Jim Quinlan)
Freescale Layerscape PCIe controller driver:
- Add suspend/resume support for Layerscape LS1043a and LS1021a,
including software-managed PME_Turn_Off and transitions between L0,
L2/L3_Ready Link states (Frank Li)
MediaTek PCIe controller driver:
- Clear MSI interrupt status before handler to avoid missing MSIs
that occur after the handler (qizhong cheng)
MediaTek PCIe Gen3 controller driver:
- Update mediatek-gen3 translation window setup to handle MMIO space
that is not a power of two in size (Jianjun Wang)
Qualcomm PCIe controller driver:
- Increase qcom iommu-map maxItems to accommodate SDX55 (five
entries) and SDM845 (sixteen entries) (Krzysztof Kozlowski)
- Describe qcom,pcie-sc8180x clocks and resets accurately (Krzysztof
Kozlowski)
- Describe qcom,pcie-sm8150 clocks and resets accurately (Krzysztof
Kozlowski)
- Correct the qcom "reset-name" property, previously incorrectly
called "reset-names" (Krzysztof Kozlowski)
- Document qcom,pcie-sm8650, based on qcom,pcie-sm8550 (Neil
Armstrong)
Renesas R-Car PCIe controller driver:
- Replace of_device.h with explicit of.h include to untangle header
usage (Rob Herring)
- Add DT and driver support for optional miniPCIe 1.5v and 3.3v
regulators on KingFisher (Wolfram Sang)
SiFive FU740 PCIe controller driver:
- Convert fu740 CONFIG_PCIE_FU740 dependency from SOC_SIFIVE to
ARCH_SIFIVE (Conor Dooley)
Synopsys DesignWare PCIe controller driver:
- Align iATU mapping for endpoint MSI-X (Niklas Cassel)
- Drop "host_" prefix from struct dw_pcie_host_ops members (Yoshihiro
Shimoda)
- Drop "ep_" prefix from struct dw_pcie_ep_ops members (Yoshihiro
Shimoda)
- Rename struct dw_pcie_ep_ops.func_conf_select() to
.get_dbi_offset() to be more descriptive (Yoshihiro Shimoda)
- Add Endpoint DBI accessors to encapsulate offset lookups (Yoshihiro
Shimoda)
TI J721E PCIe driver:
- Add j721e DT and driver support for 'num-lanes' for devices that
support x1, x2, or x4 Links (Matt Ranostay)
- Add j721e DT compatible strings and driver support for j784s4 (Matt
Ranostay)
- Make TI J721E Kconfig depend on ARCH_K3 since the hardware is
specific to those TI SoC parts (Peter Robinson)
TI Keystone PCIe controller driver:
- Hold power management references to all PHYs while enabling them to
avoid a race when one provides clocks to others (Siddharth
Vadapalli)
Xilinx XDMA PCIe controller driver:
- Remove redundant dev_err(), since platform_get_irq() and
platform_get_irq_byname() already log errors (Yang Li)
- Fix uninitialized symbols in xilinx_pl_dma_pcie_setup_irq()
(Krzysztof Wilczyński)
- Fix xilinx_pl_dma_pcie_init_irq_domain() error return when
irq_domain_add_linear() fails (Harshit Mogalapalli)
MicroSemi Switchtec management driver:
- Do dma_mrpc cleanup during switchtec_pci_remove() to match its devm
ioremapping in switchtec_pci_probe(). Previously the cleanup was
done in stdev_release(), which used stale pointers if stdev->cdev
happened to be open when the PCI device was removed (Daniel
Stodden)
Miscellaneous:
- Convert interrupt terminology from "legacy" to "INTx" to be more
specific and match spec terminology (Damien Le Moal)
- In dw-xdata-pcie, pci_endpoint_test, and vmd, replace usage of
deprecated ida_simple_*() API with ida_alloc() and ida_free()
(Christophe JAILLET)"

This is the main pin control pull request for the v6.8 kernel series.
Core changes:
- A new PINCTRL_GROUP_DESC() infrastructure macro is added and
used in different drivers, generic group description struct
group_desc is now used all over the place.
New drivers:
- New driver for the Texas Instruments TPS6494 Power Management IC.
- New driver for the Lantic PEF2256 framer pin multiplexer.
This IC has some pins that can be reconfigured in different
ways. The actual driver comes on an immutable branch with the
net WAN parts, the IC is some latest-and-greatest serial line
funnel for e.g. wireless access points.
- New subdriver for the Samsung Exynos Auto V920 pin controller,
used for automotive applications.
- New subdriver for the Samsung "GS101" SoC pin controller, this

Merge tag 'pinctrl-v6.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij:
"For this kernel cycle I managed an immutable branch for the PEF2256
WAN framer that has some pin control portions. It already landed in
your tree through the net pull request but here it is mentioned again.
The most interesting is perhaps the Samsung Exynos subdrivers for the
Tensor SoC used in Google Pixel 6 and the ExynosAuto subdriver for
automotive. Along with the earlier merged Tesla FSD subdriver it shows
some of the versatile uses of the Samsung Exynos silicon. It is also
used in the latest version of Axis Communications ARTPEC chips so it
is a very widely deployed SoC family.
We also have the Intel Meteor Lake SoC which I think is for laptops.
It's a pretty interesting chip with Xe graphics and integrated PCH.
Core changes:
- A new PINCTRL_GROUP_DESC() infrastructure macro is added and used
in different drivers, generic group description struct group_desc
is now used all over the place.
New drivers:
- New driver for the Texas Instruments TPS6494 Power Management IC.
- New driver for the Lantic PEF2256 framer pin multiplexer. This IC
has some pins that can be reconfigured in different ways. The
actual driver comes on an immutable branch with the net WAN parts,
the IC is some latest-and-greatest serial line funnel for e.g.
wireless access points.
- New subdriver for the Samsung Exynos Auto V920 pin controller, used
for automotive applications.
- New subdriver for the Samsung "GS101" SoC pin controller, this is
the Google "Tensor" SoC used in the Google Pixel 6.
- New subdriver for the Intel Meteor Point SoC pin controller.
- New subdriver for the Qualcomm SM8650 top level (TLMM) and LPASS
pin controllers.
- New subdriver for the Qualcomm X1E80100 top level (TLMM) pin
controller.
- New subdriver for the Qualcomm SM4450 top level (TLMM) pin

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. This comes with
a prefix branch shared with the arm64 tree.
- Some additional Nested Virtualization groundwork, mostly
introducing the NV2 VNCR support and retargetting the NV
support to that version of the architecture.
- A small set of vgic fixes and associated cleanups.
Loongarch:
- Optimization for memslot hugepage checking
- Cleanup and fix some HW/SW timer issues
- Add LSX/LASX (128bit/256bit SIMD) support
RISC-V:
- KVM_GET_REG_LIST improvement for vector registers
- Generate ISA extension reg_list using macros in get-reg-list selftest
- Support for reporting steal time along with selftest
s390:
- Bugfixes
Selftests:
- Fix an annoying goof where the NX hugepage test prints out garbage
instead of the magic token needed to run the test.
- Fix build errors when a header is delete/moved due to a missing flag
in the Makefile.
- Detect if KVM bugged/killed a selftest's VM and print out a helpful
message instead of complaining that a random ioctl() failed.
- Annotate the guest printf/assert helpers with __printf(), and fix the
various bugs that were lurking due to lack of said annotation.
There are two non-KVM patches buried in the middle of guest_memfd support:
fs: Rename anon_inode_getfile_secure() and anon_inode_getfd_secure()
mm: Add AS_UNMOVABLE to mark mapping as completely unmovable
The first is small and mostly suggested-by Christian Brauner; the second
a bit less so but it was written by an mm person (Vlastimil Babka).

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. This comes with a prefix
branch shared with the arm64 tree.
- Some additional Nested Virtualization groundwork, mostly
introducing the NV2 VNCR support and retargetting the NV support to
that version of the architecture.
- A small set of vgic fixes and associated cleanups.
Loongarch:
- Optimization for memslot hugepage checking
- Cleanup and fix some HW/SW timer issues
- Add LSX/LASX (128bit/256bit SIMD) support
RISC-V:
- KVM_GET_REG_LIST improvement for vector registers
- Generate ISA extension reg_list using macros in get-reg-list
selftest
- Support for reporting steal time along with selftest
s390:
- Bugfixes
Selftests:
- Fix an annoying goof where the NX hugepage test prints out garbage
instead of the magic token needed to run the test.
- Fix build errors when a header is delete/moved due to a missing
flag in the Makefile.
- Detect if KVM bugged/killed a selftest's VM and print out a helpful
message instead of complaining that a random ioctl() failed.
- Annotate the guest printf/assert helpers with __printf(), and fix
the various bugs that were lurking due to lack of said annotation"

- The proposed listmount changes are currently under my authorship. I
wasn't sure whether you'd wanted to be author as the patch wasn't
signed off. If you do I'm happy if you just apply your own patch.
I've tested the patch with my sh4 cross-build setup. And confirmed
that a) the build failure with sh on current upstream is
reproducible and that b) the proposed patch fixes the build
failure. That should only leave the task of fixing put_user on sh.
- The fsnotify regression was caused by moving one of the hooks out
of the security hook in preparation for other fsnotify work. This
meant that CONFIG_SECURITY would have compiled out the fsnotify
hook before but didn't do so now.
That lead to up to 6% performance regression in some io_uring
workloads that compile all fsnotify and security checks out. Fix
this by making sure that the relevant hooks are covered by the
already existing CONFIG_FANOTIFY_ACCESS_PERMISSIONS where the
relevant hook belongs"

s390/vfio-ap: do not reset queue removed from host config
When a queue is unbound from the vfio_ap device driver, it is reset to
ensure its crypto data is not leaked when it is bound to another device
driver. If the queue is unbound due to the fact that the adapter or domain
was removed from the host's AP configuration, then attempting to reset it
will fail with response code 01 (APID not valid) getting returned from the
reset command. Let's ensure that the queue is assigned to the host's
configuration before resetting it.

s390/vfio-ap: reset queues associated with adapter for queue unbound from driver
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.

s390/vfio-ap: reset queues filtered from the guest's AP config
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.

s390/vfio-ap: let on_scan_complete() callback filter matrix and update 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.

s390/vfio-ap: loop over the shadow APCB when filtering guest's AP configuration
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.

s390/vfio-ap: always filter entire AP matrix
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.

eventfs: Use kcalloc() instead of kzalloc()
As noted in the "Deprecated Interfaces, Language Features, Attributes, and Conventions" documentation [1], size calculations (especially multiplication) should not be performed in memory allocator (or similar) function arguments due to the risk of them overflowing. This could lead to values wrapping around and a smaller allocation being made than the caller was expecting. Using those allocations could lead to linear overflows of heap memory and other misbehaviors. So, use the purpose specific kcalloc() function instead of the argument size * count in the kzalloc() function.

eventfs: Do not create dentries nor inodes in iterate_shared
The original eventfs code added a wrapper around the dcache_readdir open
callback and created all the dentries and inodes at open, and increment
their ref count. A wrapper was added around the dcache_readdir release
function to decrement all the ref counts of those created inodes and
dentries. But this proved to be buggy[1] for when a kprobe was created
during a dir read, it would create a dentry between the open and the
release, and because the release would decrement all ref counts of all
files and directories, that would include the kprobe directory that was
not there to have its ref count incremented in open. This would cause the
ref count to go to negative and later crash the kernel.
To solve this, the dentries and inodes that were created and had their ref
count upped in open needed to be saved. That list needed to be passed from
the open to the release, so that the release would only decrement the ref
counts of the entries that were incremented in the open.
Unfortunately, the dcache_readdir logic was already using the
file->private_data, which is the only field that can be used to pass
information from the open to the release. What was done was the eventfs
created another descriptor that had a void pointer to save the
dcache_readdir pointer, and it wrapped all the callbacks, so that it could
save the list of entries that had their ref counts incremented in the
open, and pass it to the release. The wrapped callbacks would just put
back the dcache_readdir pointer and call the functions it used so it could
still use its data[2].
But Linus had an issue with the "hijacking" of the file->private_data
(unfortunately this discussion was on a security list, so no public link).
Which we finally agreed on doing everything within the iterate_shared
callback and leave the dcache_readdir out of it[3]. All the information
needed for the getents() could be created then.
But this ended up being buggy too[4]. The iterate_shared callback was not
the right place to create the dentries and inodes. Even Christian Brauner
had issues with that[5].
An attempt was to go back to creating the inodes and dentries at
the open, create an array to store the information in the
file->private_data, and pass that information to the other callbacks.[6]
The difference between that and the original method, is that it does not
use dcache_readdir. It also does not up the ref counts of the dentries and
pass them. Instead, it creates an array of a structure that saves the
dentry's name and inode number. That information is used in the
iterate_shared callback, and the array is freed in the dir release. The
dentries and inodes created in the open are not used for the iterate_share
or release callbacks. Just their names and inode numbers.
Linus did not like that either[7] and just wanted to remove the dentries
being created in iterate_shared and use the hard coded inode numbers.
[ All this while Linus enjoyed an unexpected vacation during the merge
window due to lack of power. ]
