kvm: defer huge page recovery vhost task to later (2025-01-24 10:53:56 -0500)

There is a conflict in arch/x86/kvm/cpuid.c that is nasty to describe
because the affected area has been completely rewritten, but is really a
one liner. The change to be reproduced is commit 716f86b523d8 ("KVM:
x86: Advertise SRSO_USER_KERNEL_NO to userspace"):

but you can throw away the <<<< ... ==== part completely, and apply the
same change on top of the new implementation:

I cannot blame Boris at all for including the change to cpuid.c, since
this file has never been much of a source of conflicts (and is not
expected to become one in the future).

Thanks,

Paolo

----------------------------------------------------------------
Loongarch:

* Clear LLBCTL if secondary mmu mapping changes.

* Add hypercall service support for usermode VMM.

x86:

* Add a comment to kvm_mmu_do_page_fault() to explain why KVM performs a
direct call to kvm_tdp_page_fault() when RETPOLINE is enabled.

* Ensure that all SEV code is compiled out when disabled in Kconfig, even
if building with less brilliant compilers.

* Remove a redundant TLB flush on AMD processors when guest CR4.PGE changes.

* Use str_enabled_disabled() to replace open coded strings.

* Drop kvm_x86_ops.hwapic_irr_update() as KVM updates hardware's APICv cache
prior to every VM-Enter.

* Overhaul KVM's CPUID feature infrastructure to track all vCPU capabilities
instead of just those where KVM needs to manage state and/or explicitly
enable the feature in hardware. Along the way, refactor the code to make
it easier to add features, and to make it more self-documenting how KVM
is handling each feature.

* Rework KVM's handling of VM-Exits during event vectoring; this plugs holes
where KVM unintentionally puts the vCPU into infinite loops in some scenarios
(e.g. if emulation is triggered by the exit), and brings parity between VMX
and SVM.

* Add pending request and interrupt injection information to the kvm_exit and
kvm_entry tracepoints respectively.

* Fix a relatively benign flaw where KVM would end up redoing RDPKRU when
loading guest/host PKRU, due to a refactoring of the kernel helpers that
didn't account for KVM's pre-checking of the need to do WRPKRU.

* Make the completion of hypercalls go through the complete_hypercall
function pointer argument, no matter if the hypercall exits to
userspace or not. Previously, the code assumed that KVM_HC_MAP_GPA_RANGE
specifically went to userspace, and all the others did not; the new code
need not special case KVM_HC_MAP_GPA_RANGE and in fact does not care at
all whether there was an exit to userspace or not.

* As part of enabling TDX virtual machines, support support separation of
private/shared EPT into separate roots. When TDX will be enabled, operations
on private pages will need to go through the privileged TDX Module via SEAMCALLs;
as a result, they are limited and relatively slow compared to reading a PTE.
The patches included in 6.14 allow KVM to keep a mirror of the private EPT in
host memory, and define entries in kvm_x86_ops to operate on external page
tables such as the TDX private EPT.

* The recently introduced conversion of the NX-page reclamation kthread to
vhost_task moved the task under the main process. The task is created as
soon as KVM_CREATE_VM was invoked and this, of course, broke userspace that
didn't expect to see any child task of the VM process until it started
creating its own userspace threads. In particular crosvm refuses to fork()
if procfs shows any child task, so unbreak it by creating the task lazily.
This is arguably a userspace bug, as there can be other kinds of legitimate
worker tasks and they wouldn't impede fork(); but it's not like userspace
has a way to distinguish kernel worker tasks right now. Should they show
as "Kthread: 1" in proc/.../status?

x86 - Intel:

* Fix a bug where KVM updates hardware's APICv cache of the highest ISR bit
while L2 is active, while ultimately results in a hardware-accelerated L1
EOI effectively being lost.

* Honor event priority when emulating Posted Interrupt delivery during nested
VM-Enter by queueing KVM_REQ_EVENT instead of immediately handling the
interrupt.

* Rework KVM's processing of the Page-Modification Logging buffer to reap
entries in the same order they were created, i.e. to mark gfns dirty in the
same order that hardware marked the page/PTE dirty.

* Misc cleanups.

Generic:

* Cleanup and harden kvm_set_memory_region(); add proper lockdep assertions when
setting memory regions and add a dedicated API for setting KVM-internal
memory regions. The API can then explicitly disallow all flags for
KVM-internal memory regions.

* Explicitly verify the target vCPU is online in kvm_get_vcpu() to fix a bug
where KVM would return a pointer to a vCPU prior to it being fully online,
and give kvm_for_each_vcpu() similar treatment to fix a similar flaw.

* Wait for a vCPU to come online prior to executing a vCPU ioctl, to fix a
bug where userspace could coerce KVM into handling the ioctl on a vCPU that
isn't yet onlined.

* Gracefully handle xarray insertion failures; even though such failures are
impossible in practice after xa_reserve(), reserving an entry is always followed
by xa_store() which does not know (or differentiate) whether there was an
xa_reserve() before or not.

RISC-V:

* Zabha, Svvptc, and Ziccrse extension support for guests. None of them
require anything in KVM except for detecting them and marking them
as supported; Zabha adds byte and halfword atomic operations, while the
others are markers for specific operation of the TLB and of LL/SC
instructions respectively.

* Virtualize SBI system suspend extension for Guest/VM

* Support firmware counters which can be used by the guests to collect
statistics about traps that occur in the host.

Selftests:

* Rework vcpu_get_reg() to return a value instead of using an out-param, and
update all affected arch code accordingly.

* Convert the max_guest_memory_test into a more generic mmu_stress_test.
The basic gist of the "conversion" is to have the test do mprotect() on
guest memory while vCPUs are accessing said memory, e.g. to verify KVM
and mmu_notifiers are working as intended.

* Play nice with treewrite builds of unsupported architectures, e.g. arm
(32-bit), as KVM selftests' Makefile doesn't do anything to ensure the
target architecture is actually one KVM selftests supports.

* Use the kernel's $(ARCH) definition instead of the target triple for arch
specific directories, e.g. arm64 instead of aarch64, mainly so as not to
be different from the rest of the kernel.

* Ensure that format strings for logging statements are checked by the
compiler even when the logging statement itself is disabled.

* Attempt to whack the last LLC references/misses mole in the Intel PMU
counters test by adding a data load and doing CLFLUSH{OPT} on the data
instead of the code being executed. It seems 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 events
are counting correctly without actually knowing what the events count
given the underlying hardware; this can happen if Intel reuses a
formerly microarchitecture-specific event encoding as an architectural
event, as was the case for Top-Down Slots.
