For all 32-bit systems and 64-bit Windows systems, "long" is 4 bytes long.
Due to using "long" for a linear address, svm_canonicalization would
set all high bits to 1 when (assuming 48-bit linear address) the segment
base is bigger than 0x7FFF.
This fixes booting guests under TCG when the guest IDT and GDT bases are
above 0x7FFF, thereby resulting in incorrect bases. When an interrupt
arrives, it would trigger a #PF exception; the #PF would trigger again,
resulting in a #DF exception; the #PF would trigger for the third time,
resulting in triple-fault, and eventually causes a shutdown VM-Exit to
the hypervisor right after guest boot.

Update the header makes it different from the original kernel that user
provides via "-kernel", which leads to a different hash and breaks the
attestation, e.g., for TDX.
We already skip it for SEV VMs. Instead of adding another check of
is_tdx_vm() to cover the TDX case, check machine->cgs to cover all the
confidential computing case for x86.

For now, qemu save/load CPU exception info(such as exception_nr and
has_error_code), while the exception error_code is ignored. This will
cause the dest hypervisor reinject a vCPU exception with error_code(0),
potentially causing a guest kernel panic.
For instance, if src VM stopped with an user-mode write #PF (error_code 6),
the dest hypervisor will reinject an #PF with error_code(0) when vCPU resume,
then guest kernel panic as:
BUG: unable to handle page fault for address: 00007f80319cb010
#PF: supervisor read access in user mode
#PF: error_code(0x0000) - not-present page
RIP: 0033:0x40115d
To fix it, support save/load exception error_code.

This reverts commit 00268e00027459abede448662f8794d78eb4b0a4.
(The only conflict is in the !is_tdx_vm() part of the condition,
which is safe to keep).
mark_unavailable_features() actively blocks usage of the feature,
so it is a functional change, not merely a emitting warning.
The commit was intended to merely warn if PDCM was enabled when
the performance counters are not, so revert it.

qemu_rbd_get_specific_info() has at least two problems:
The first is that it issues a blocking rbd_read() call in order to probe
the encryption format for the image while querying the node. This means
that if the connection to the server goes down, not only I/O is stuck
(which is unavoidable), but query-names-block-nodes will actually make
the whole QEMU instance unresponsive. .bdrv_get_specific_info
implementations shouldn't perform blocking operations, but only return
what is already known.
The second is that the information returned isn't even correct. If the
image is already opened with encryption enabled at the RBD level, we'll
probe for "double encryption", i.e. if the encrypted data contains
another encryption header. If it doesn't (which is the normal case), we
won't return the encryption format. If it does, we return misleading
information because it looks like we're talking about the outer level
(the encryption format of the image itself) while the information is
about an encryption header in the guest data.
Fix this by storing the encryption format in BDRVRBDState when the image
is opened (and we do blocking operations anyway) and returning only the
stored information in qemu_rbd_get_specific_info().
The information we'll store is either the actual encryption format that
we enabled on the RBD level, or if the image is unencrypted, the result
of the same probing as we previously did when querying the node. Probing
image formats based on content that can be modified by the guest has
long been known as problematic, but as long as we only output it to the
user instead of making decisions based on it, it should be okay. It is
undoubtedly useful in the context of 'qemu-img info' when you're trying
to figure out which encryption options you have to use to open the
image successfully.

When the guest writes to register UEFI_VARS_REG_BUFFER_SIZE, the .write
callback `uefi_vars_write` is invoked. The function allocates a
heap buffer without zeroing the memory, leaving the buffer filled with
residual data from prior allocations. When the guest later reads from
register UEFI_VARS_REG_PIO_BUFFER_TRANSFER, the .read callback
`uefi_vars_read` returns leftover metadata or other sensitive process
memory from the previously allocated buffer, leading to an information
disclosure vulnerability.

The emulated device had let the user set whatever max transfers size
they wanted, including no limit. However the device does have an
internal limit of 1024 segments. NVMe doesn't report max segments,
though. This is implicitly inferred based on the MDTS and MPSMIN values.
IOV_MAX is currently 1024 which 4k PRPs can exceed with 2MB transfers.
Don't allow MDTS values that can exceed this, otherwise users risk
seeing "internal error" status to their otherwise protocol compliant
commands.

cpr-transfer may lose a VFIO interrupt because the KVM instance is
destroyed and recreated. If an interrupt arrives in the middle, it is
dropped. To fix, stop pending new interrupts during cpr save, and pick
up the pieces. In more detail:
Stop the VCPUs. Call kvm_irqchip_remove_irqfd_notifier_gsi --> KVM_IRQFD to
deassign the irqfd gsi that routes interrupts directly to the VCPU and KVM.
After this call, interrupts fall back to the kernel vfio_msihandler, which
writes to QEMU's kvm_interrupt eventfd. CPR already preserves that
eventfd. When the route is re-established in new QEMU, the kernel tests
the eventfd and injects an interrupt to KVM if necessary.
Deassign INTx in a similar manner. For both MSI and INTx, remove the
eventfd handler so old QEMU does not consume an event.
If an interrupt was already pended to KVM prior to the completion of
kvm_irqchip_remove_irqfd_notifier_gsi, it will be recovered by the
subsequent call to cpu_synchronize_all_states, which pulls KVM interrupt
state to userland prior to saving it in vmstate.

Commit v9.0.0-343-g2048129625 introduced usage of
g_file_set_contents() function to write to /sys/power/state.
This function uses G_FILE_SET_CONTENTS_CONSISTENT flag to
g_file_set_contents_full(), which is implemented by creating
a temp file in the same directory and renaming it to the final
destination. Which is not how sysfs works.
Here, there's not a big deal to do open/write/close - it becomes
almost the same as using g_file_set_contents[_full](). But it
does not have surprises like this.
Also, since this is linux code, it should be ok to use %m in
the error reporting function.

With a microvm-only build based on a custom device config,
we get a link failure due to undefined reference to
build_pci_host_bridge_osc_method() which is defined in hw/acpi/pci.c and
whose compilation depends on CONFIG_ACPI_PCI. Although CONFIG_ACPI
and CONFIG_PCI are set with such configuration, implied CONFIG_ACPI_PCI
in config PCI_EXPRESS_GENERIC_BRIDGE is not selected as expected.
It Looks like CONFIG_ACPI_PCI must be enforced and this patch selects
CONFIG_ACPI_PCI in MICROVM config directly as done for PC config.

CPUID[0x1]
Currently, the addressable ID encoding for CPUID[0x1].EBX[bits 16-23]
(Maximum number of addressable IDs for logical processors in this
physical package) is covered by vendor_cpuid_only_v2 compat property.
The previous consideration was to avoid breaking migration and this
compat property makes it unfriendly to backport the commit f985a1195ba2
("i386/cpu: Fix number of addressable IDs field for CPUID.01H.EBX
[23:16]").
However, NetBSD booting is broken since the commit 88dd4ca06c83
("i386/cpu: Use APIC ID info to encode cache topo in CPUID[4]"),
because NetBSD calculates smt information via `lp_max` / `core_max` for
legacy Intel CPUs which doesn't support 0xb leaf, where `lp_max` is from
CPUID[0x1].EBX.bits[16-23] and `core_max` is from CPUID[0x4].0x0.bits[26
-31].
The commit 88dd4ca0 changed the encoding rule of `core_max` but didn't
update `lp_max`, so that NetBSD would get the wrong smt information,
which leads to the module loading failure.
Luckily, the commit f985a1195ba2 ("i386/cpu: Fix number of addressable
IDs field for CPUID.01H.EBX[23:16]") updated the encoding rule for
`lp_max` and accidentally fixed the NetBSD issue too. This also shows
that using CPUID[0x1] and CPUID[0x4].0x0 to calculate HT/SMT information
is a common practice to detect CPU topology on legacy Intel CPUs.
Therefore, it's necessary to backport the commit f985a1195ba2 to
previous stable QEMU to help address the similar issues as well. Then
the compat property is not needed any more since all stable QEMUs will
follow the same encoding way.
So, in CPUID[0x1], move addressable ID encoding out of compat property.

SD card mode is a superset of its state (SDState::state),
no need to migrate it.
Use sd_mode() to get the SDCardModes from the SDCardStates.

The card should be in STANDBY mode to process SEND_CSD or SEND_CID,
but is still in IDLE mode.
Unfortunately I don't have enough time to keep debugging this issue,
so disable the check for the time being and the next release, as it
blocks Linux. I'll keep looking.
