[PATCH v3 00/25] KVM: arm64: Introduce pKVM hyp VM and vCPU state at EL2

[Will Deacon]

Hi folks,

This is v3 of the series previously posted here:

  Mega-series: https://lore.kernel.org/kvmarm/20220519134204.5379-1-will@kernel.org/
  v2: https://lore.kernel.org/all/20220630135747.26983-1-will@kernel.org/

There have been some significant changes since v2, including:

- Removal of unnecessary backpointer linking a hyp vCPU to its hyp VM in
  favour of container_of()

- Removing confusing use of 'shadow' at EL2 in favour of 'pkvm_hyp'
  (although this was much more work than a simple sed expression!)

- Simplified vm table lookup and removal of redundant table traversal

- Rework of the hypervisor fixmap to avoid redundant page-table walks

- Splitting of memory donations required to create a guest so that the
  requirement for physically-contiguous pages is reduced

- Fixed a memory leak when the stage-2 pgd is configured with an
  unsupported size

- Dropped rework of 'struct hyp_page' as it is not required by this
  series

- Improved commit messages

- Rebased onto v6.0-rc1

Oliver -- as discussed in person, I've left the owner ID enumeration
where it is for now since we will need to track the guest *instance* in
future and so consolidating this into the pgtable code is unlikely to be
beneficial.

As with the previous posting, the last patch is marked as RFC because,
although it plumbs in the shadow state, it is woefully inefficient and
copies to/from the host state on every vCPU run. Without the last patch,
the new structures are unused but we move considerably closer to
isolating guests from the host.

Cheers,

Will, Quentin, Fuad and Marc

[PATCH v3 01/25] KVM: arm64: Move hyp refcount manipulation helpers to common header file

[Will Deacon]

From: Quentin Perret <qperret@google.com>

We will soon need to manipulate 'struct hyp_page' refcounts from outside
page_alloc.c, so move the helpers to a common header file to allow them
to be reused easily.

[PATCH v3 02/25] KVM: arm64: Allow attaching of non-coalescable pages to a hyp pool

[Will Deacon]

From: Quentin Perret <qperret@google.com>

All the contiguous pages used to initialize a 'struct hyp_pool' are
considered coalescable, which means that the hyp page allocator will
actively try to merge them with their buddies on the hyp_put_page() path.
However, using hyp_put_page() on a page that is not part of the inital
memory range given to a hyp_pool() is currently unsupported.

In order to allow dynamically extending hyp pools at run-time, add a
check to __hyp_attach_page() to allow inserting 'external' pages into
the free-list of order 0. This will be necessary to allow lazy donation
of pages from the host to the hypervisor when allocating guest stage-2
page-table pages at EL2.

[PATCH v3 03/25] KVM: arm64: Back the hypervisor 'struct hyp_page' array for all memory

[Will Deacon]

From: Quentin Perret <qperret@google.com>

The EL2 'vmemmap' array in nVHE Protected mode is currently very sparse:
only memory pages owned by the hypervisor itself have a matching 'struct
hyp_page'. However, as the size of this struct has been reduced
significantly since its introduction, it appears that we can now afford
to back the vmemmap for all of memory.

Having an easily accessible 'struct hyp_page' for every physical page in
memory provides the hypervisor with a simple mechanism to store metadata
(e.g. a refcount) that wouldn't otherwise fit in the very limited number
of software bits available in the host stage-2 page-table entries. This
will be used in subsequent patches when pinning host memory pages for
use by the hypervisor at EL2.

[PATCH v3 04/25] KVM: arm64: Fix-up hyp stage-1 refcounts for all pages mapped at EL2

[Will Deacon]

From: Quentin Perret <qperret@google.com>

In order to allow unmapping arbitrary memory pages from the hypervisor
stage-1 page-table, fix-up the initial refcount for pages that have been
mapped before the 'vmemmap' array was up and running so that it
accurately accounts for all existing hypervisor mappings.

This is achieved by traversing the entire hypervisor stage-1 page-table
during initialisation of EL2 and updating the corresponding

[PATCH v3 05/25] KVM: arm64: Unify identifiers used to distinguish host and hypervisor

[Will Deacon]

The 'pkvm_component_id' enum type provides constants to refer to the
host and the hypervisor, yet this information is duplicated by the
'pkvm_hyp_id' constant.

Remove the definition of 'pkvm_hyp_id' and move the 'pkvm_component_id'
type definition to 'mem_protect.h' so that it can be used outside of
the memory protection code, for example when initialising the owner for
hypervisor-owned pages.

[PATCH v3 06/25] KVM: arm64: Implement do_donate() helper for donating memory

[Will Deacon]

From: Quentin Perret <qperret@google.com>

Transferring ownership information of a memory region from one component
to another can be achieved using a "donate" operation, which results
in the previous owner losing access to the underlying pages entirely
and the new owner having exclusive access to the page.

Implement a do_donate() helper, along the same lines as do_{un,}share,
and provide this functionality for the host-{to,from}-hyp cases as this
will later be used to donate/reclaim memory pages to store VM metadata
at EL2.

In a similar manner to the sharing transitions, permission checks are
performed by the hypervisor to ensure that the component initiating the
transition really is the owner of the page and also that the completer
does not currently have a page mapped at the target address.

[PATCH v3 07/25] KVM: arm64: Prevent the donation of no-map pages

[Will Deacon]

From: Quentin Perret <qperret@google.com>

Memory regions marked as "no-map" in the host device-tree routinely
include TrustZone carevouts and DMA pools. Although donating such pages
to the hypervisor may not breach confidentiality, it could be used to
corrupt its state in uncontrollable ways. To prevent this, let's block
host-initiated memory transitions targeting "no-map" pages altogether in
nVHE protected mode as there should be no valid reason to do this in
current operation.

Thankfully, the pKVM EL2 hypervisor has a full copy of the host's list
of memblock regions, so we can easily check for the presence of the
MEMBLOCK_NOMAP flag on a region containing pages being donated from the
host.

[PATCH v3 08/25] KVM: arm64: Add helpers to pin memory shared with the hypervisor at EL2

[Will Deacon]

From: Quentin Perret <qperret@google.com>

Add helpers allowing the hypervisor to check whether a range of pages
are currently shared by the host, and 'pin' them if so by blocking host
unshare operations until the memory has been unpinned.

This will allow the hypervisor to take references on host-provided
data-structures (e.g. 'struct kvm') with the guarantee that these pages
will remain in a stable state until the hypervisor decides to release
them, for example during guest teardown.

[PATCH v3 09/25] KVM: arm64: Include asm/kvm_mmu.h in nvhe/mem_protect.h

[Will Deacon]

nvhe/mem_protect.h refers to __load_stage2() in the definition of
__load_host_stage2() but doesn't include the relevant header.

Include asm/kvm_mmu.h in nvhe/mem_protect.h so that users of the latter
don't have to do this themselves.

[PATCH v3 10/25] KVM: arm64: Add hyp_spinlock_t static initializer

[Will Deacon]

From: Fuad Tabba <tabba@google.com>

Introduce a static initializer macro for 'hyp_spinlock_t' so that it is
straightforward to instantiate global locks at EL2. This will be later
utilised for locking the VM table in the hypervisor.

[PATCH v3 11/25] KVM: arm64: Rename 'host_kvm' to 'host_mmu'

[Will Deacon]

In preparation for introducing VM and vCPU state at EL2, rename the
existing 'struct host_kvm' and its singleton 'host_kvm' instance to
'host_mmu' so as to avoid confusion between the structure tracking the
host stage-2 MMU state and the host instance of a 'struct kvm' for a
protected guest.

[PATCH v3 12/25] KVM: arm64: Add infrastructure to create and track pKVM instances at EL2

[Will Deacon]

From: Fuad Tabba <tabba@google.com>

Introduce a global table (and lock) to track pKVM instances at EL2, and
provide hypercalls that can be used by the untrusted host to create and
destroy pKVM VMs and their vCPUs. pKVM VM/vCPU state is directly
accessible only by the trusted hypervisor (EL2).

Each pKVM VM is directly associated with an untrusted host KVM instance,
and is referenced by the host using an opaque handle. Future patches
will provide hypercalls to allow the host to initialize/set/get pKVM
VM/vCPU state using the opaque handle.

[PATCH v3 13/25] KVM: arm64: Instantiate pKVM hypervisor VM and vCPU structures from EL1

[Will Deacon]

From: Fuad Tabba <tabba@google.com>

With the pKVM hypervisor at EL2 now offering hypercalls to the host for
creating and destroying VM and vCPU structures, plumb these in to the
existing arm64 KVM backend to ensure that the hypervisor data structures
are allocated and initialised on first vCPU run for a pKVM guest.

In the host, 'struct kvm_protected_vm' is introduced to hold the handle
of the pKVM VM instance as well as to track references to the memory
donated to the hypervisor so that it can be freed back to the host
allocator following VM teardown. The stage-2 page-table, hypervisor VM
and vCPU structures are allocated separately so as to avoid the need for
a large physically-contiguous allocation in the host at run-time.

[PATCH v3 14/25] KVM: arm64: Add per-cpu fixmap infrastructure at EL2

[Will Deacon]

From: Quentin Perret <qperret@google.com>

Mapping pages in a guest page-table from within the pKVM hypervisor at
EL2 may require cache maintenance to ensure that the initialised page
contents is visible even to non-cacheable (e.g. MMU-off) accesses from
the guest.

In preparation for performing this maintenance at EL2, introduce a
per-vCPU fixmap which allows the pKVM hypervisor to map guest pages
temporarily into its stage-1 page-table for the purposes of cache
maintenance and, in future, poisoning on the reclaim path. The use of a
fixmap avoids the need for memory allocation or locking on the map()
path.

[PATCH v3 15/25] KVM: arm64: Initialise hypervisor copies of host symbols unconditionally

[Will Deacon]

The nVHE object at EL2 maintains its own copies of some host variables
so that, when pKVM is enabled, the host cannot directly modify the
hypervisor state. When running in normal nVHE mode, however, these
variables are still mirrored at EL2 but are not initialised.

Initialise the hypervisor symbols from the host copies regardless of
pKVM, ensuring that any reference to this data at EL2 with normal nVHE
will return a sensibly initialised value.

[PATCH v3 16/25] KVM: arm64: Provide I-cache invalidation by virtual address at EL2

[Will Deacon]

In preparation for handling cache maintenance of guest pages from within
the pKVM hypervisor at EL2, introduce an EL2 copy of icache_inval_pou()
which will later be plumbed into the stage-2 page-table cache
maintenance callbacks, ensuring that the initial contents of pages
mapped as executable into the guest stage-2 page-table is visible to the
instruction fetcher.

[PATCH v3 17/25] KVM: arm64: Add generic hyp_memcache helpers

[Will Deacon]

From: Quentin Perret <qperret@google.com>

The host at EL1 and the pKVM hypervisor at EL2 will soon need to
exchange memory pages dynamically for creating and destroying VM state.

Indeed, the hypervisor will rely on the host to donate memory pages it
can use to create guest stage-2 page-tables and to store VM and vCPU
metadata. In order to ease this process, introduce a
'struct hyp_memcache' which is essentially a linked list of available
pages, indexed by physical addresses so that it can be passed
meaningfully between the different virtual address spaces configured at
EL1 and EL2.

[PATCH v3 18/25] KVM: arm64: Consolidate stage-2 initialisation into a single function

[Will Deacon]

From: Quentin Perret <qperret@google.com>

The initialisation of guest stage-2 page-tables is currently split
across two functions: kvm_init_stage2_mmu() and kvm_arm_setup_stage2().
That is presumably for historical reasons as kvm_arm_setup_stage2()
originates from the (now defunct) KVM port for 32-bit Arm.

Simplify this code path by merging both functions into one, taking care
to map the 'struct kvm' into the hypervisor stage-1 early on in order to
simplify the failure path.

[PATCH v3 19/25] KVM: arm64: Instantiate guest stage-2 page-tables at EL2

[Will Deacon]

From: Quentin Perret <qperret@google.com>

Extend the initialisation of guest data structures within the pKVM
hypervisor at EL2 so that we instantiate a memory pool and a full
'struct kvm_s2_mmu' structure for each VM, with a stage-2 page-table
entirely independent from the one managed by the host at EL1.

The 'struct kvm_pgtable_mm_ops' used by the page-table code is populated
with a set of callbacks that can manage guest pages in the hypervisor
without any direct intervention from the host, allocating page-table
pages from the provided pool and returning these to the host on VM
teardown. To keep things simple, the stage-2 MMU for the guest is
configured identically to the host stage-2 in the VTCR register and so
the IPA size of the guest must match the PA size of the host.

For now, the new page-table is unused as there is no way for the host
to map anything into it. Yet.

[PATCH v3 20/25] KVM: arm64: Return guest memory from EL2 via dedicated teardown memcache

[Will Deacon]

From: Quentin Perret <qperret@google.com>

Rather than relying on the host to free the previously-donated pKVM
hypervisor VM pages explicitly on teardown, introduce a dedicated
teardown memcache which allows the host to reclaim guest memory
resources without having to keep track of all of the allocations made by
the pKVM hypervisor at EL2.

[PATCH v3 21/25] KVM: arm64: Unmap 'kvm_arm_hyp_percpu_base' from the host

[Will Deacon]

From: Quentin Perret <qperret@google.com>

When pKVM is enabled, the hypervisor at EL2 does not trust the host at
EL1 and must therefore prevent it from having unrestricted access to
internal hypervisor state.

The 'kvm_arm_hyp_percpu_base' array holds the offsets for hypervisor
per-cpu allocations, so move this this into the nVHE code where it
cannot be modified by the untrusted host at EL1.

[PATCH v3 22/25] KVM: arm64: Maintain a copy of 'kvm_arm_vmid_bits' at EL2

[Will Deacon]

Sharing 'kvm_arm_vmid_bits' between EL1 and EL2 allows the host to
modify the variable arbitrarily, potentially leading to all sorts of
shenanians as this is used to configure the VTTBR register for the
guest stage-2.

In preparation for unmapping host sections entirely from EL2, maintain
a copy of 'kvm_arm_vmid_bits' in the pKVM hypervisor and initialise it
from the host value while it is still trusted.

[PATCH v3 23/25] KVM: arm64: Explicitly map 'kvm_vgic_global_state' at EL2

[Will Deacon]

From: Quentin Perret <qperret@google.com>

The pkvm hypervisor at EL2 may need to read the 'kvm_vgic_global_state'
variable from the host, for example when saving and restoring the state
of the virtual GIC.

Explicitly map 'kvm_vgic_global_state' in the stage-1 page-table of the
pKVM hypervisor rather than relying on mapping all of the host '.rodata'
section.

[Will Deacon]

From: Quentin Perret <qperret@google.com>

We no longer need to map the host's '.rodata' and '.bss' sections in the
stage-1 page-table of the pKVM hypervisor at EL2, so remove those
mappings and avoid creating any future dependencies at EL2 on
host-controlled data structures.

[RFC PATCH v3 25/25] KVM: arm64: Use the pKVM hyp vCPU structure in handle___kvm_vcpu_run()

[Will Deacon]

As a stepping stone towards deprivileging the host's access to the
guest's vCPU structures, introduce some naive flush/sync routines to
copy most of the host vCPU into the hyp vCPU on vCPU run and back
again on return to EL1.

This allows us to run using the pKVM hyp structures when KVM is
initialised in protected mode.
