a243c16d18 KVM: arm64: Add capability to advertise ptrauth for guest
This patch advertises the capability of two cpu feature called address
pointer authentication and generic pointer authentication. These
capabilities depend upon system support for pointer authentication and
VHE mode.

The current arm64 KVM partially implements pointer authentication and
support of address/generic authentication are tied together. However,
separate ABI requirements for both of them is added so that any future
isolated implementation will not require any ABI changes.

This features will allow the KVM guest to allow the handling of
pointer authentication instructions or to treat them as undefined
if not set.

fe365b4ea6 KVM: Clarify KVM_{SET,GET}_ONE_REG error code documentation
The current error code documentation for KVM_GET_ONE_REG and
KVM_SET_ONE_REG could be read as implying that all architectures
implement these error codes, or that KVM guarantees which error
code is returned in a particular situation.

Because this is not really the case, this patch waters down the
documentation explicitly to remove such guarantees.

EPERM is marked as arm64-specific, since for now arm64 really is
the only architecture that yields this error code for the
finalization-required case.  Keeping this as a distinct error code
is useful however for debugging due to the statefulness of the API
in this instance.

No functional change.

9df2d660c7 KVM: Clarify capability requirements for KVM_ARM_VCPU_FINALIZE
Userspace is only supposed to use KVM_ARM_VCPU_FINALIZE when there
is some vcpu feature that can actually be finalized.

This means that documenting KVM_ARM_VCPU_FINALIZE as available or
not depending on the capabilities present is not helpful.

This patch amends the documentation to describe availability in
terms of which capability is required for each finalizable feature
instead.

In any case, userspace sees the same error (EINVAL) regardless of
whether the given feature is not present or KVM_ARM_VCPU_FINALIZE
is not implemented at all.

No functional change.

4bd774e57b KVM: arm64/sve: Simplify KVM_REG_ARM64_SVE_VLS array sizing
A complicated DIV_ROUND_UP() expression is currently written out
explicitly in multiple places in order to specify the size of the
bitmap exchanged with userspace to represent the value of the
KVM_REG_ARM64_SVE_VLS pseudo-register.

Userspace currently has no direct way to work this out either: for
documentation purposes, the size is just quoted as 8 u64s.

To make this more intuitive, this patch replaces these with a
single define, which is also exported to userspace as
KVM_ARM64_SVE_VLS_WORDS.

Since the number of words in a bitmap is just the index of the last
word used + 1, this patch expresses the bound that way instead.
This should make it clearer what is being expressed.

For userspace convenience, the minimum and maximum possible vector
lengths relevant to the KVM ABI are exposed to UAPI as
KVM_ARM64_SVE_VQ_MIN, KVM_ARM64_SVE_VQ_MAX.  Since the only direct
use for these at present is manipulation of KVM_REG_ARM64_SVE_VLS,
no corresponding _VL_ macros are defined.  They could be added
later if a need arises.

Since use of DIV_ROUND_UP() was the only reason for including
<linux/kernel.h> in guest.c, this patch also removes that #include.

919f6cd8bb KVM: doc: Document the life cycle of a VM and its resources
The series to add memcg accounting to KVM allocations[1] states:

  There are many KVM kernel memory allocations which are tied to the
  life of the VM process and should be charged to the VM process's
  cgroup.

While it is correct to account KVM kernel allocations to the cgroup of
the process that created the VM, it's technically incorrect to state
that the KVM kernel memory allocations are tied to the life of the VM

indefinitely; kvm_destroy_vm() isn't called until Qemu closes its file
descriptor *and* the rogue child is killed.

created the VM, but only because KVM's per-{VM,vCPU} ioctls reject the

the VM "alive" but can't do anything useful with its reference.

Alternatively, KVM could aggressively free resources when the creating
process exits, e.g. via mmu_notifier->release().  However, mmu_notifier
isn't guaranteed to be available, and freeing resources when the creator
exits is likely to be error prone and fragile as KVM would need to
ensure that it only freed resources that are truly out of reach. In
practice, the existing behavior shouldn't be problematic as a properly
configured system will prevent a child process from being moved out of
the appropriate cgroup hierarchy, i.e. prevent hiding the process from
the OOM killer, and will prevent an unprivileged user from being able to
to hold a reference to struct kvm via another method, e.g. debugfs.

ddba91801a KVM: Reject device ioctls from processes other than the VM's creator
KVM's API requires thats ioctls must be issued from the same process
that created the VM.  In other words, userspace can play games with a
VM's file descriptors, e.g. fork(), SCM_RIGHTS, etc..., but only the
creator can do anything useful.  Explicitly reject device ioctls that
are issued by a process other than the VM's creator, and update KVM's
API documentation to extend its requirements to device ioctls.

5e124900c6 KVM: doc: Fix incorrect word ordering regarding supported use of APIs
Per Paolo[1], instantiating multiple VMs in a single process is legal;
but this conflicts with KVM's API documentation, which states:

  The only supported use is one virtual machine per process, and one
  vcpu per thread.

However, an earlier section in the documentation states:

   Only run VM ioctls from the same process (address space) that was used
   to create the VM.

and:

   Only run vcpu ioctls from the same thread that was used to create the
   vcpu.

This suggests that the conflicting documentation is simply an incorrect
ordering of of words, i.e. what's really meant is that a virtual machine
can't be shared across multiple processes and a vCPU can't be shared
across multiple threads.

Tweak the blurb on issuing ioctls to use a more assertive tone, and
rewrite the "supported use" sentence to reference said blurb instead of
poorly restating it in different terms.

Opportunistically add missing punctuation.

eca6be566d KVM: doc: Document the life cycle of a VM and its resources
The series to add memcg accounting to KVM allocations[1] states:

  There are many KVM kernel memory allocations which are tied to the
  life of the VM process and should be charged to the VM process's
  cgroup.

While it is correct to account KVM kernel allocations to the cgroup of
the process that created the VM, it's technically incorrect to state
that the KVM kernel memory allocations are tied to the life of the VM
process.  This is because the VM itself, i.e. struct kvm, is not tied to

2bc39970e9 x86/kvm/hyper-v: Introduce KVM_GET_SUPPORTED_HV_CPUID
With every new Hyper-V Enlightenment we implement we're forced to add a
KVM_CAP_HYPERV_* capability. While this approach works it is fairly
inconvenient: the majority of the enlightenments we do have corresponding
CPUID feature bit(s) and userspace has to know this anyways to be able to
expose the feature to the guest.

Add KVM_GET_SUPPORTED_HV_CPUID ioctl (backed by KVM_CAP_HYPERV_CPUID, "one
cap to rule them all!") returning all Hyper-V CPUID feature leaves.

Using the existing KVM_GET_SUPPORTED_CPUID doesn't seem to be possible:
Hyper-V CPUID feature leaves intersect with KVM's (e.g. 0x40000000,
0x40000001) and we would probably confuse userspace in case we decide to
return these twice.

KVM_CAP_HYPERV_CPUID's number is interim: we're intended to drop
KVM_CAP_HYPERV_STIMER_DIRECT and use its number instead.

2a31b9db15 kvm: introduce manual dirty log reprotect
There are two problems with KVM_GET_DIRTY_LOG.  First, and less important,
it can take kvm->mmu_lock for an extended period of time.  Second, its user
can actually see many false positives in some cases.  The latter is due
to a benign race like this:

  1. KVM_GET_DIRTY_LOG returns a set of dirty pages and write protects
     them.
  2. The guest modifies the pages, causing them to be marked ditry.
  3. Userspace actually copies the pages.
  4. KVM_GET_DIRTY_LOG returns those pages as dirty again, even though
     they were not written to since (3).

This is especially a problem for large guests, where the time between
(1) and (3) can be substantial.  This patch introduces a new
capability which, when enabled, makes KVM_GET_DIRTY_LOG not
write-protect the pages it returns.  Instead, userspace has to
explicitly clear the dirty log bits just before using the content
of the page.  The new KVM_CLEAR_DIRTY_LOG ioctl can also operate on a
64-page granularity rather than requiring to sync a full memslot;
this way, the mmu_lock is taken for small amounts of time, and
only a small amount of time will pass between write protection
of pages and the sending of their content.

c4f55198c7 kvm: x86: Introduce KVM_CAP_EXCEPTION_PAYLOAD
This is a per-VM capability which can be enabled by userspace so that
the faulting linear address will be included with the information
about a pending #PF in L2, and the "new DR6 bits" will be included
with the information about a pending #DB in L2. With this capability
enabled, the L1 hypervisor can now intercept #PF before CR2 is
modified. Under VMX, the L1 hypervisor can now intercept #DB before
DR6 and DR7 are modified.

When userspace has enabled KVM_CAP_EXCEPTION_PAYLOAD, it should
generally provide an appropriate payload when injecting a #PF or #DB
exception via KVM_SET_VCPU_EVENTS. However, to support restoring old
checkpoints, this payload is not required.

Note that bit 16 of the "new DR6 bits" is set to indicate that a debug
exception (#DB) or a breakpoint exception (#BP) occurred inside an RTM
region while advanced debugging of RTM transactional regions was
enabled. This is the reverse of DR6.RTM, which is cleared in this
scenario.

This capability also enables exception.pending in struct
kvm_vcpu_events, which allows userspace to distinguish between pending
and injected exceptions.

59073aaf6d kvm: x86: Add exception payload fields to kvm_vcpu_events
The per-VM capability KVM_CAP_EXCEPTION_PAYLOAD (to be introduced in a
later commit) adds the following fields to struct kvm_vcpu_events:
exception_has_payload, exception_payload, and exception.pending.

With this capability set, all of the details of vcpu->arch.exception,
including the payload for a pending exception, are reported to
userspace in response to KVM_GET_VCPU_EVENTS.

With this capability clear, the original ABI is preserved, and the
exception.injected field is set for either pending or injected
exceptions.

When userspace calls KVM_SET_VCPU_EVENTS with
KVM_CAP_EXCEPTION_PAYLOAD clear, exception.injected is no longer
translated to exception.pending. KVM_SET_VCPU_EVENTS can now only
establish a pending exception when KVM_CAP_EXCEPTION_PAYLOAD is set.

0804c849f1 kvm/x86 : add coalesced pio support
Coalesced pio is based on coalesced mmio and can be used for some port
like rtc port, pci-host config port and so on.

Specially in case of rtc as coalesced pio, some versions of windows guest
access rtc frequently because of rtc as system tick. guest access rtc like
this: write register index to 0x70, then write or read data from 0x71.
writing 0x70 port is just as index and do nothing else. So we can use
coalesced pio to handle this scene to reduce VM-EXIT time.

When starting and closing a virtual machine, it will access pci-host config
port frequently. So setting these port as coalesced pio can reduce startup
and shutdown time.

without my patch, get the vm-exit time of accessing rtc 0x70 and piix 0xcf8

of the IPA to host limit and allow lower IPA sizes (e.g, 32).

The userspace could check the extension KVM_CAP_ARM_VM_IPA_SIZE

maximum limit for the physical address shift supported by the host.

ucontrol VMs are rather exotic and creating a new locking concept is

the moment when the process was interrupted to save its state.

With this capability, there are two new vcpu ioctls: KVM_GET_NESTED_STATE

that is in VMX operation.

a449938297 KVM: s390: Add huge page enablement control
General KVM huge page support on s390 has to be enabled via the
kvm.hpage module parameter. Either nested or hpage can be enabled, as
we currently do not support vSIE for huge backed guests. Once the vSIE
support is added we will either drop the parameter or enable it as
default.

For a guest the feature has to be enabled through the new
KVM_CAP_S390_HPAGE_1M capability and the hpage module
parameter. Enabling it means that cmm can't be enabled for the vm and
disables pfmf and storage key interpretation.

This is due to the fact that in some cases, in upcoming patches, we
have to split huge pages in the guest mapping to be able to set more
granular memory protection on 4k pages. These split pages have fake
page tables that are not visible to the Linux memory management which
subsequently will not manage its PGSTEs, while the SIE will. Disabling
these features lets us manage PGSTE data in a consistent matter and
solve that problem.

be26b3a734 arm64: KVM: export the capability to set guest SError syndrome
For the arm64 RAS Extension, user space can inject a virtual-SError
with specified ESR. So user space needs to know whether KVM support
to inject such SError, this interface adds this query for this capability.

KVM will check whether system support RAS Extension, if supported, KVM
returns true to user space, otherwise returns false.

b7b27facc7 arm/arm64: KVM: Add KVM_GET/SET_VCPU_EVENTS
For the migrating VMs, user space may need to know the exception
state. For example, in the machine A, KVM make an SError pending,
when migrate to B, KVM also needs to pend an SError.

This new IOCTL exports user-invisible states related to SError.
Together with appropriate user space changes, user space can get/set
the SError exception state to do migrate/snapshot/suspend.
