[PATCH v6 00/13] Add PCI pass-thru support to Hyper-V Confidential VMs

[PATCH v6 00/13] Add PCI pass-thru support to Hyper-V Confidential VMs

[Michael Kelley]

This patch series adds support for PCI pass-thru devices to Hyper-V
Confidential VMs (also called "Isolation VMs"). But in preparation, it
first changes how private (encrypted) vs. shared (decrypted) memory is
handled in Hyper-V SEV-SNP guest VMs. The new approach builds on the
confidential computing (coco) mechanisms introduced in the 5.19 kernel
for TDX support and significantly reduces the amount of Hyper-V specific
code. Furthermore, with this new approach a proposed RFC patch set for
generic DMA layer functionality[1] is no longer necessary.

Background
==========
Hyper-V guests on AMD SEV-SNP hardware have the option of using the
"virtual Top Of Memory" (vTOM) feature specified by the SEV-SNP
architecture. With vTOM, shared vs. private memory accesses are
controlled by splitting the guest physical address space into two
halves.  vTOM is the dividing line where the uppermost bit of the
physical address space is set; e.g., with 47 bits of guest physical
address space, vTOM is 0x400000000000 (bit 46 is set).  Guest physical
memory is accessible at two parallel physical addresses -- one below
vTOM and one above vTOM.  Accesses below vTOM are private (encrypted)
while accesses above vTOM are shared (decrypted). In this sense, vTOM
is like the GPA.SHARED bit in Intel TDX.

In Hyper-V's use of vTOM, the normal guest OS runs at VMPL2, while
a Hyper-V provided "paravisor" runs at VMPL0 in the guest VM. (VMPL is
Virtual Machine Privilege Level. See AMD's SEV-SNP spec for more
details.) The paravisor provides emulation for various system devices
like the IO-APIC and TPM as part of the guest VM.  Accesses to such
devices made by the normal guest OS trap to the paravisor and are emulated
in the guest VM context instead of in the Hyper-V host. This emulation is
invisible to the normal guest OS, but with the quirk that memory mapped
I/O accesses to these devices must be treated as private, not shared as
would be the case for other device accesses.

Support for Hyper-V guests using vTOM was added to the Linux kernel
in two patch sets[2][3]. This support treats the vTOM bit as part of
the physical address.  For accessing shared (decrypted) memory, the core
approach is to create a second kernel virtual mapping that maps to
parallel physical addresses above vTOM, while leaving the original
mapping unchanged.  Most of the code for creating that second virtual
mapping is confined to Hyper-V specific areas, but there are also
changes to generic swiotlb code.

Changes in this patch set
=========================
In preparation for supporting PCI pass-thru devices, this patch set
changes the core approach for handling vTOM. In the new approach,
the vTOM bit is treated as a protection flag, and not as part of
the physical address. This new approach is like the approach for
the GPA.SHARED bit in Intel TDX.  Furthermore, there's no need to
create a second kernel virtual mapping.  When memory is changed
between private and shared using set_memory_decrypted() and
set_memory_encrypted(), the PTEs for the existing kernel mapping
are changed to add or remove the vTOM bit just as with TDX. The
hypercalls to change the memory status on the host side are made
using the existing callback mechanism. Everything just works, with
a minor tweak to map the IO-APIC and TPM to use private accesses
as mentioned above.

With the new handling of vTOM in place, existing Hyper-V code that
creates the second kernel virtual mapping still works, but it is now
redundant as the original kernel virtual mapping (as updated) maps
to the same physical address. To simplify things going forward, this
patch set removes the code that creates the second kernel virtual
mapping. And since a second kernel virtual mapping is no longer
needed, changes to the DMA layer proposed as an RFC[1] are no
longer needed.

Finally, to support PCI pass-thru in a Confidential VM, Hyper-V
requires that all accesses to PCI config space be emulated using
a hypercall.  This patch set adds functions to invoke those
hypercalls and uses them in the config space access functions
in the Hyper-V PCI driver. Lastly, the Hyper-V PCI driver is
marked as allowed to be used in a Confidential VM.  The Hyper-V
PCI driver has been hardened against a malicious Hyper-V in a
previous patch set.[4]

Patch Organization
==================
Patches 1 thru 5 are prepatory patches to account for
slightly different assumptions when running in a Hyper-V VM
with vTOM, and to make temporary tweaks to avoid needing a single
large patch to make the transition from the old approach to
the new approach.

Patch 6 enables the new approach to handling vTOM for Hyper-V
guest VMs. This is the core patch after which the new approach
is in effect.

Patches 7 thru 10 remove existing code for creating the second
kernel virtual mapping that is no longer necessary with the
new approach.

Patch 11 updates existing code so that it no longer assumes that
the vTOM bit is part of the physical address.

Patches 12 and 13 add new hypercalls for accessing MMIO space
and use those hypercalls for PCI config space. They also enable
the Hyper-V vPCI driver to be used in a Confidential VM.

These patches are built against the linux-next20230307 tree.

Changes in v6:
* Redo Patch 1 to use a hypervisor callback to determine if an
  MMIO mapping should be private. [Sean Christopherson]

* Remove Patch 6 since it is replaced by the new hypervisor
  callback in Patch 1

* Update the previous Patch 7 (now Patch 6) to set up the
  new hypervisor callback and return "true" when mapping the
  IO-APIC or TPM.

* Minor tweaks to rebase to linux-next20230307

Changes in v5:
* Add new Patch 6 and update hv_vtom_init() in Patch 7 so that
  the virtual TPM in the guest is mapped as encrypted

* Update commit messages for Patches 1 thru 4, and 12 [Boris Petkov]

* Remove the Fixes tag in Patch 4 after discussion upstream
  [Boris Petkov, Tom Lendacky, others]

* Use PAGE_KERNEL instead of PAGE_KERNEL_NOENC in arch independent
  Hyper-V code. PAGE_KERNEL_NOENC doesn't exist for ARM64, so it
  causes compile errors. Using PAGE_KERNEL means or'ing in
  sme_me_mask when on x86, but it will be zero for vTOM VMs.

* In patch 6, break out amd_cc_platform_has() handling of vTOM
  into a separate helper function [Boris Petkov]

Changes in v4:
* Remove previous Patch 1 from this series and submit separately
  [Dave Hansen & Boris Petkov]

* Patch 1: Change the name of the new CC_ATTR that controls
  whether the IO-APIC is mapped decrypted [Boris Petkov]

* Patch 4: Use sme_me_mask directly instead of calling the
  getter function. Add Fixes: tag. [Tom Lendacky]

* Patch 6: Remove CC_VENDOR_HYPERV and merge associated
  vTOM functionality under CC_VENDOR_AMD. [Boris Petkov]

* Patch 8: Use bitwise OR to pick up the vTOM bit in
  shared_gpa_boundary rather than adding it

Changes in v3:
* Patch 1: Tweak the code fix to cleanly separate the page
  alignment and physical address masking [Dave Hansen]

* Patch 2: Change the name of the new CC_ATTR that controls
  whether the IO-APIC is mapped decrypted [Dave Hansen]

* Patch 5 (now patch 7): Add CC_ATTR_MEM_ENCRYPT to what
  Hyper-V vTOM reports as 'true'. With the addition, Patches
  5 and 6 are new to accomodate working correctly with Hyper-V
  VMs using vTOM. [Tom Lendacky]

Changes in v2:
* Patch 11: Include more detail in the error message if an MMIO
  hypercall fails. [Bjorn Helgaas]

* Patch 12: Restore removed memory barriers. It seems like these
  barriers should not be needed because of the spin_unlock() calls,
  but commit bdd74440d9e8 indicates that they are. This patch series
  will leave the barriers unchanged; whether they are really needed
  can be sorted out separately. [Boqun Feng]

[PATCH v6 01/13] x86/ioremap: Add hypervisor callback for private MMIO mapping in coco VM

[Michael Kelley]

Current code always maps MMIO devices as shared (decrypted) in a
confidential computing VM. But Hyper-V guest VMs on AMD SEV-SNP with vTOM
use a paravisor running in VMPL0 to emulate some devices, such as the
IO-APIC and TPM. In such a case, the device must be accessed as private
(encrypted) because the paravisor emulates the device at an address below
vTOM, where all accesses are encrypted.

Add a new hypervisor callback to determine if an MMIO address should
be mapped private. The callback allows hypervisor-specific code to handle
any quirks, the use of a paravisor, etc. in determining whether a mapping
must be private. If the callback is not used by a hypervisor, default
to returning "false", which is consistent with normal coco VM behavior.

Use this callback as another special case to check for when doing ioremap.
Just checking the starting address is sufficient as an ioremap range must
be all private or all shared.

Also make the callback in early boot IO-APIC mapping code that uses the
fixmap.

[PATCH v6 03/13] Drivers: hv: Explicitly request decrypted in vmap_pfn() calls

[Michael Kelley]

Update vmap_pfn() calls to explicitly request that the mapping
be for decrypted access to the memory.  There's no change in
functionality since the PFNs passed to vmap_pfn() are above the
shared_gpa_boundary, implicitly producing a decrypted mapping.
But explicitly requesting "decrypted" allows the code to work
before and after changes that cause vmap_pfn() to mask the
PFNs to being below the shared_gpa_boundary.

[PATCH v6 04/13] x86/mm: Handle decryption/re-encryption of bss_decrypted consistently

[Michael Kelley]

sme_postprocess_startup() decrypts the bss_decrypted section when
sme_me_mask is non-zero.

mem_encrypt_free_decrypted_mem() re-encrypts the unused portion based
on CC_ATTR_MEM_ENCRYPT.

In a Hyper-V guest VM using vTOM, these conditions are not equivalent
as sme_me_mask is always zero when using vTOM. Consequently,
mem_encrypt_free_decrypted_mem() attempts to re-encrypt memory that was
never decrypted.

So check sme_me_mask in mem_encrypt_free_decrypted_mem() too.

Hyper-V guests using vTOM don't need the bss_decrypted section to be
decrypted, so skipping the decryption/re-encryption doesn't cause a
problem.

[PATCH v6 05/13] init: Call mem_encrypt_init() after Hyper-V hypercall init is done

[Michael Kelley]

Full Hyper-V initialization, including support for hypercalls, is done
as an apic_post_init callback via late_time_init().  mem_encrypt_init()
needs to make hypercalls when it marks swiotlb memory as decrypted.
But mem_encrypt_init() is currently called a few lines before
late_time_init(), so the hypercalls don't work.

Fix this by moving mem_encrypt_init() after late_time_init() and
related clock initializations. The intervening initializations don't
do any I/O that requires the swiotlb, so moving mem_encrypt_init()
slightly later has no impact.

[PATCH v6 06/13] x86/hyperv: Change vTOM handling to use standard coco mechanisms

[Michael Kelley]

Hyper-V guests on AMD SEV-SNP hardware have the option of using the
"virtual Top Of Memory" (vTOM) feature specified by the SEV-SNP
architecture. With vTOM, shared vs. private memory accesses are
controlled by splitting the guest physical address space into two
halves.  vTOM is the dividing line where the uppermost bit of the
physical address space is set; e.g., with 47 bits of guest physical
address space, vTOM is 0x400000000000 (bit 46 is set).  Guest physical
memory is accessible at two parallel physical addresses -- one below
vTOM and one above vTOM.  Accesses below vTOM are private (encrypted)
while accesses above vTOM are shared (decrypted). In this sense, vTOM
is like the GPA.SHARED bit in Intel TDX.

Support for Hyper-V guests using vTOM was added to the Linux kernel in
two patch sets[1][2]. This support treats the vTOM bit as part of
the physical address. For accessing shared (decrypted) memory, these
patch sets create a second kernel virtual mapping that maps to physical
addresses above vTOM.

A better approach is to treat the vTOM bit as a protection flag, not
as part of the physical address. This new approach is like the approach
for the GPA.SHARED bit in Intel TDX. Rather than creating a second kernel
virtual mapping, the existing mapping is updated using recently added
coco mechanisms.  When memory is changed between private and shared using
set_memory_decrypted() and set_memory_encrypted(), the PTEs for the
existing kernel mapping are changed to add or remove the vTOM bit
in the guest physical address, just as with TDX. The hypercalls to
change the memory status on the host side are made using the existing
callback mechanism. Everything just works, with a minor tweak to map
the IO-APIC to use private accesses.

To accomplish the switch in approach, the following must be done:

* Update Hyper-V initialization to set the cc_mask based on vTOM
  and do other coco initialization.

* Update physical_mask so the vTOM bit is no longer treated as part
  of the physical address

* Remove CC_VENDOR_HYPERV and merge the associated vTOM functionality
  under CC_VENDOR_AMD. Update cc_mkenc() and cc_mkdec() to set/clear
  the vTOM bit as a protection flag.

* Code already exists to make hypercalls to inform Hyper-V about pages
  changing between shared and private.  Update this code to run as a
  callback from __set_memory_enc_pgtable().

* Remove the Hyper-V special case from __set_memory_enc_dec()

* Remove the Hyper-V specific call to swiotlb_update_mem_attributes()
  since mem_encrypt_init() will now do it.

* Add a Hyper-V specific implementation of the is_private_mmio()
  callback that returns true for the IO-APIC and vTPM MMIO addresses

[PATCH v6 07/13] swiotlb: Remove bounce buffer remapping for Hyper-V

[Michael Kelley]

With changes to how Hyper-V guest VMs flip memory between private
(encrypted) and shared (decrypted), creating a second kernel virtual
mapping for shared memory is no longer necessary. Everything needed
for the transition to shared is handled by set_memory_decrypted().

As such, remove swiotlb_unencrypted_base and the associated
code.

[PATCH v6 08/13] Drivers: hv: vmbus: Remove second mapping of VMBus monitor pages

[Michael Kelley]

With changes to how Hyper-V guest VMs flip memory between private
(encrypted) and shared (decrypted), creating a second kernel virtual
mapping for shared memory is no longer necessary.  Everything needed
for the transition to shared is handled by set_memory_decrypted().

As such, remove the code to create and manage the second
mapping for VMBus monitor pages. Because set_memory_decrypted()
and set_memory_encrypted() are no-ops in normal VMs, it's
not even necessary to test for being in a Confidential VM
(a.k.a., "Isolation VM").

[PATCH v6 09/13] Drivers: hv: vmbus: Remove second way of mapping ring buffers

[Michael Kelley]

With changes to how Hyper-V guest VMs flip memory between private
(encrypted) and shared (decrypted), it's no longer necessary to
have separate code paths for mapping VMBus ring buffers for
for normal VMs and for Confidential VMs.

As such, remove the code path that uses vmap_pfn(), and set
the protection flags argument to vmap() to account for the
difference between normal and Confidential VMs.

[PATCH v6 10/13] hv_netvsc: Remove second mapping of send and recv buffers

[Michael Kelley]

With changes to how Hyper-V guest VMs flip memory between private
(encrypted) and shared (decrypted), creating a second kernel virtual
mapping for shared memory is no longer necessary.  Everything needed
for the transition to shared is handled by set_memory_decrypted().

As such, remove the code to create and manage the second
mapping for the pre-allocated send and recv buffers.  This mapping
is the last user of hv_map_memory()/hv_unmap_memory(), so delete
these functions as well.  Finally, hv_map_memory() is the last
user of vmap_pfn() in Hyper-V guest code, so remove the Kconfig
selection of VMAP_PFN.

[PATCH v6 11/13] Drivers: hv: Don't remap addresses that are above shared_gpa_boundary

[Michael Kelley]

With the vTOM bit now treated as a protection flag and not part of
the physical address, avoid remapping physical addresses with vTOM set
since technically such addresses aren't valid.  Use ioremap_cache()
instead of memremap() to ensure that the mapping provides decrypted
access, which will correctly set the vTOM bit as a protection flag.

While this change is not required for correctness with the current
implementation of memremap(), for general code hygiene it's better to
not depend on the mapping functions doing something reasonable with
a physical address that is out-of-range.

While here, fix typos in two error messages.

[PATCH v6 13/13] PCI: hv: Enable PCI pass-thru devices in Confidential VMs

[Michael Kelley]

For PCI pass-thru devices in a Confidential VM, Hyper-V requires
that PCI config space be accessed via hypercalls.  In normal VMs,
config space accesses are trapped to the Hyper-V host and emulated.
But in a confidential VM, the host can't access guest memory to
decode the instruction for emulation, so an explicit hypercall must
be used.

Update the PCI config space access functions to use the hypercalls
when such use is indicated by Hyper-V flags.  Also, set the flag to
allow the Hyper-V PCI driver to be loaded and used in a Confidential
VM (a.k.a., "Isolation VM").  The driver has previously been hardened
against a malicious Hyper-V host[1].

This is silly. It should simply be:

			return val;

So if you set the C-bit, that doesn't make it decrypted on AMD. cc_mask
on VTOM is 0 so why even bother?

Same as the above.

This looks like a hack. The SEV status MSR cannot be intercepted so the

The x86 bits look pretty much ready modulo some uncertainties in patch 6.

When this has all been clarified I'm thinking of taking patches

1-2,4-6

through tip and giving an immutable branch to HyperV maintainers to base
the rest ontop...

To be clear, cc_mask contains the vTOM bit.  It's not zero.  See the
call to cc_set_mask() further down below.  My code makes sure the
vTOM bit is *not* set for the encrypted case, just like the
CC_VENDOR_INTEL code below does for the TDX SHARED bit.

cc_mask is *not* zero in the vTOM case.  It contains the vTOM bit.
The C-bit is not used or set in the vTOM case.

In a vTOM VM, CPUID leaf 0x8000001f is filtered so it does *not* return
Bit 1 (SEV) as set.  Consequently, sme_enable() does not read MSR_AMD64_SEV
and does not populate sev_status.  The Linux boot sequence proceeds as if
SEV-SNP (and any other memory encryption) is *not* enabled, which is the
whole point of vTOM mode.  The tricky SME/SEV code for setting the C-bit,
getting the kernel encrypted, etc. is not needed or wanted because the
hardware already encrypts all memory by default.  The bootloader runs
with memory encrypted, it loads the kernel into encrypted memory, and
so forth.

sev_status is used here only to communicate to cc_platform_has() and
cc_mkenc() and cc_mkdec() that we're in vTOM mode.  If using sev_status
to communicate is confusing, this could just as easily be some new global
variable, and sev_status could be left as all zeros.

So how much of the hardware side of vTOM are you actually using besides
the actual encryption?

Virtual TOM MSR (C001_0135)? Anything else?

AFAICT, you're passing the vTOM value from CPUID from the hypervisor so
I'm guessing that happens underneath in the hypervisor?

I'd like to make sure there are no more "surprises" down the road...

vTOM mode in Linux is just turning on/off the vTOM bit in the PTE
to create unencrypted or encrypted mappings, with encrypted being the
default.  There's no other hardware dependency except CPUID leaf
0x8000001f reporting that SEV is not enabled, and the GHCB protocol
(if you want to call that "hardware") as mentioned below.

Correct.  Linux in vTOM mode is not reading MSR 0xC0010135.  The
PTE bit position of the vTOM bit is coming from Hyper-V (or the paravisor)
via a synthetic MSR.  Presumably Hyper-V or the paravisor is reading
the vTOM MSR, but I haven't reviewed that code.

> 
> I'd like to make sure there are no more "surprises" down the road...

The only other vTOM changes are for software protocols for communication
between the guest and Hyper-V (or the paravisor).  Some hypercalls and
synthetic MSR accesses need to bypass the paravisor and are handled
with the GHCB protocol.  The Hyper-V and VMbus specific code in Linux
handles those idiosyncrasies.  That code went into the 5.15 kernel and
isn't modified by this patch set.

The vTOM case is down to the bare minimum in the use of the hardware
functionality, so it's unlikely anything else would turn up as being different.

Nit: I'd squash this in with the patch where the calls are used,
don't think this patch is bisectable as it stands (maybe you
split them for review purposes, apologies if so).

I did split the new code into two patches to make it more
consumable from a review standpoint.  But I'm not understanding
what you mean by not being bisectable.  After applying the first
of the two patches, everything should still compile and work
even though there are no users of the new hypercalls.  Or maybe
your concern is that there would be "unused function" warnings?

In any case, squashing the two patches isn't a problem.

If you have config dependency, I think you should fix it in the code or add
Kconfig dependency.

That's why it is called randconfig builds. That doesn't mean that they
should not build properly.

OK, I see what went wrong.  I had tested with CONFIG_AMD_MEM_ENCRYPT=n
and didn't see any compile problems.  It turns out in my test, arch/x86/coco/core.c
wasn't built at all because I did not also have TDX configured, so I didn't see
any errors.  But with CONFIG_INTEL_TDX_GUEST=y, coco/core.c gets built, and
the error with undefined sev_status pops out.

The straightforward fix is somewhat ugly.  That's to put #ifdef
CONFIG_AMD_MEM_ENCRYPT around the entire CC_VENDOR_AMD
case in cc_mkenc() and in cc_mkdec().  Or put it just around the test of
sev_status.

Perhaps a cleaner way would be to have a "vendor_subtype" variable
declared in arch/x86/coco/core.c and tested instead of sev_status.
That subtype variable would be set from hv_vtom_init(), maybe via
a separate accessor function.  But didn't I recently see a patch that
makes the existing "vendor" variable no longer static?   In that case
just setting vendor_subtype without the accessor function may be
OK.

What's your preference Boris?  I can spin a v7 of the patch series
that fixes this, and that squashes the last two patches of the series
per Lorenz Pieralisi's comments.

Actually, a pretty clean approach is to #define sev_status 0ULL in
the #else /* !CONFIG_AMD_MEM_ENCRYPT */ half of
arch/x86/include/asm/mem_encrypt.h.   That's where the existing
extern statement is, and  sme_me_mask is already handled that way.

I'll respin the patch set with that approach.

[tip: x86/sev] init: Call mem_encrypt_init() after Hyper-V hypercall init is done

init: Call mem_encrypt_init() after Hyper-V hypercall init is done

Full Hyper-V initialization, including support for hypercalls, is done
as an apic_post_init callback via late_time_init().  mem_encrypt_init()
needs to make hypercalls when it marks swiotlb memory as decrypted.
But mem_encrypt_init() is currently called a few lines before
late_time_init(), so the hypercalls don't work.

Fix this by moving mem_encrypt_init() after late_time_init() and
related clock initializations. The intervening initializations don't
do any I/O that requires the swiotlb, so moving mem_encrypt_init()
slightly later has no impact.

x86/mm: Handle decryption/re-encryption of bss_decrypted consistently

sme_postprocess_startup() decrypts the bss_decrypted section when
sme_me_mask is non-zero.

mem_encrypt_free_decrypted_mem() re-encrypts the unused portion based
on CC_ATTR_MEM_ENCRYPT.

In a Hyper-V guest VM using vTOM, these conditions are not equivalent
as sme_me_mask is always zero when using vTOM. Consequently,
mem_encrypt_free_decrypted_mem() attempts to re-encrypt memory that was
never decrypted.

So check sme_me_mask in mem_encrypt_free_decrypted_mem() too.

Hyper-V guests using vTOM don't need the bss_decrypted section to be
decrypted, so skipping the decryption/re-encryption doesn't cause a
problem.

x86/ioremap: Add hypervisor callback for private MMIO mapping in coco VM

Current code always maps MMIO devices as shared (decrypted) in a
confidential computing VM. But Hyper-V guest VMs on AMD SEV-SNP with vTOM
use a paravisor running in VMPL0 to emulate some devices, such as the
IO-APIC and TPM. In such a case, the device must be accessed as private
(encrypted) because the paravisor emulates the device at an address below
vTOM, where all accesses are encrypted.

Add a new hypervisor callback to determine if an MMIO address should
be mapped private. The callback allows hypervisor-specific code to handle
any quirks, the use of a paravisor, etc. in determining whether a mapping
must be private. If the callback is not used by a hypervisor, default
to returning "false", which is consistent with normal coco VM behavior.

Use this callback as another special case to check for when doing
ioremap().  Just checking the starting address is sufficient as an
ioremap range must be all private or all shared.

Also make the callback in early boot IO-APIC mapping code that uses the
fixmap.
