7536a95424 misc: cleanup &Arc<dyn T> -> &dyn T
Consuming `&Arc<T>` as argument is almost always an antipattern as it
hides whether the callee is going to take over (shared) ownership
(by .clone()) or not. Instead, it is better to consume `&dyn T` or
`Arc<dyn T>` to be more explicit. This commit cleans up the code.

The change is very mechanic and was very easy to implement across the
code base.

3e339439a4 arch: move GICv2M SPI base to leave room for legacy IRQs
Move the GICv2M MSI frame SPI base from 32 to 128 to avoid conflicts
with platform device interrupts.

While at it, rename the constants to make it explicit that they are
associated with the GICv2m MSI Frame.

cb5aaca809 hypervisor, vmm: Remove inner Mutex protecting VcpuFd
This was added in 7be69edf51 to deal with
changes to the KVM bindings that made run() and set_immediate_exit()
take &mut self. Instead adopt a Box<> value in Vcpu allowing the removal
of this internal Mutex.

d39b56544a vmm: fix CpuManager::resume(): gracefully wait for run vCPU loop ACK
Fix a race condition that happens in resume()-pause() cycles.

It is odd that for pause(), the CpuManager waited via `state.paused`
for the vCPU thread to ACK the state change but not for `resume()`.
In the `resume()` case, oddly CpuManager "owned" the state change
in `state.paused`. This commit changes this so that the vCPU ACKs
its state change itself in `state.paused` when it transitions from
pause->run. Further, `CpuManager::resume()` now gracefully waits for
the vCPU to be resumed.

More technical:

This change ensures proper synchronization and prevents situations
in that park() follows right after unpark(), causing deadlocks and
other weird behavior due to race conditions.

Calling resume() now takes slightly longer, very similar to pause().
This is, however, even for 254 vCPUs in the range of less than 10ms,
and ultimately we now have correct behaviour.

## Reproducer

Since [0] is merged, the underlying problem can be tested without this
commit by modifying the pause() API call to run `CpuManager::pause()`
and `CpuManager::resume()` in a loop a thousand times.

`ch-remote --api-socket ... pause`

## Outlook

Decades of experience in VMM development showed us that using
many AtomicBools is a footgun. They are not synchronized with each
other at all. On the long term, we might want to refactor things to
have a single shared AtomicU64 with different bits having different
meanings.

8481026b60 vmm: refactor poor naming
These bindings actually refer to atomic bool shared across all
vCPUs to instruct single vCPUs with their next action. As there
are already enough Arc<AtomicBool>, this helps while debugging
things to see that different bindings refer to the same atomic
bool.

In other words: This naming really confused us while debugging.

256f0c39e9 vmm: Drop 'vfio container' when no active vfio devices
This provides clearer life-cycle management of resources around vfio,
and aligns better with the kernel behavior as reported below with vfio
legacy mode (with vfio container/group).

Fixes: #7328

no kernel or firmware. This patch fixes the sev_snp boot
failure.

5549d846da vmm: support firmware boot on mshv arm64
MSHV (Microsoft Hypervisor) doesn't expose an ITS to guests. Instead it
exposes a GICv2m MSI Frame for mapping MSIs to SPIs.

Update the MADT generation code to create the GIC MSI Frame structure
instead of the ITS structure whenever the guest vGIC is using a GICv2m
frame. This allows booting guests via firmware on MSHV.

690741de13 hypervisor: kvm/x86_64: get and set nested guest state
Since the functionality of [0] was backported to
kvm-bindings@v0.12.1 and kvm-ioctls@v0.22.1 [1, 2], we
can now save nested KVM state. This way, nesting works across
state save/resume and live-migration.

4c16285dde vmm: Fix UB in AMX support checks
Rust's aliasing rules do not permit mutating a `usize` through a shared
reference. Unsafe blocks and FFI are no exception.

This PR fixes such a violation detected in the AMX support checks by
passing a raw mutable pointer instead of a shared reference in the
syscall.

a6426e3615 devices: gracefully close preserved FDs on device remove
For a graceful resource management of externally provided FDs in Cloud
Hypervisor, corresponding FDs need to be closed on a device removal.
This is the case for virtio-net devices using external FDs, for example.

With the fix introduced in this commit, we allow management software to
properly clean up resources, e.g., libvirt can clean up tap devices.

PS: CHV uses "added" and "removed", which has the same meaning as
hot device attach/hotplug and hot device detach/unplug.

452424b66e vmm: api: abstract FD handling behind functions
## TL;DR

This unifies error handling, implementation, and logging of config
objects that are populated with additional FDs received as part of
the HTTP API request from the management software. This prevents current
and future code in repetition.

In the future, if we want to support let's say virtio-blk with external
FDs, the AddBlk API handler simply needs a call to `attach_fds_to_cfg()`
and gets all the magic for free.

## Motivation

The motivation of the new abstraction is to provide a verbose, solid,
and bulletproof solution for a complex domain. The interaction between

- the management layer,
- the passing of file descriptors over UNIX domain sockets via
  SCM_RIGHTS,
- the attachment of configurations to those FDs,
- and the ability to give new developers clear insights into what
  happens under the hood

is not trivial. These factors justify encapsulating the complexity
behind a convenient and well-documented abstraction, making the system
both robust in production and approachable for new developers.

In addition, it allows us to perform unit testing. Further, We get rid
of existing partial code duplication and inconsistencies.

Finally, while this approach may initially result in more code, every
new handler that accepts FDs benefits from reduced duplication and a
correct implementation by relying on the shared abstraction. This will
also enable future functionality, such as virtio-blk devices backed by
FDs which can then be integrated with ease.

ed27e93b81 vmm: remove special serialization of network FDs
Deserializing values as `-1` makes sense to prevent errors, so let's
keep it. However, serializing them differently adds confusion. For
example, a `ch-remote info` call should not report `-1` but the actual
FDs.

0cd87053ee vmm: document + FD (de)serialization + warn -> debug
(1) The old messages are missing the "why" part. With this change, users
    of Cloud Hypervisor have somehow more context and people looking at
    the code perfectly know what's going on.

(2) Using warn! implies that the user should take action, but in this
    case, there’s nothing the user can do. If the API is used correctly
    and file descriptors are passed via an SCM_RIGHTS message over a
    UNIX domain socket, everything works as intended. In that case,
    there's no need to issue a warning — debug! is sufficient.

60efa1aa03 vmm: doc improvement for "magic" network FD handling
Live migration, state save/resume, and hotplug are not trivial when it
comes to virtio-net devices backed by externally provided FDs. As the
mechanism behind it can be considered as quite "multi-step magic" even
for experienced programmers, it makes sense to thoroughly document this
to ease debugging and to improve the mental model of developers working
on this in the future.

66aa0743f0 vmm: allow net devices without ip and mask
This change enables easier integration with third-party
tools by removing the requirement for a dummy IP address
when configuring tap devices. The modification applies to
both CLI and API interactions.

Previously, cloud-hypervisor would automatically set a
default static IP address (192.168.249.1) if none was provided.

This could lead to:

* multiple devices without explicit IP configurations
  would end up with the same default IP
* unnecessary inclusion of this IP in firewall rules
* the IP address could clash with host networking and
  routing

This introduces a new constraint:
When providing an IP, the mask must also be provided.

Removes warnings introduced in #7179.
Closes issue #7083.

Since the user has to explicitly ask for Landlock to be enabled in
Cloud Hypervisor, it's surprising that, even when they've done that,
Landlock will silently not be enabled if the kernel doesn't support
it.

with an error if Landlock, or the one feature of it we use in Cloud
Hypervisor (file access) is not supported.

`clippy::missing_safety_doc` only works for public functions
but none of the corresponding functions is public.

2c6426460e vmm: harmonize bootpath across architectures
On aarch64 and RISC-V, calling load_firmware() through load_kernel()
provides no benefit and only duplicates checks already performed in
load_payload(). load_payload() now directly invokes load_firmware() or
load_kernel(), removing unnecessary indirection and redundancy.

1a63b4b2ff vmm: Consolidate 'load_firmware/kernel' for aarch64 and riscv
Both functions are defined separately for the two architecture with
minor differences.

* `load_firmware()`: call `arch::uefi::load_uefi` which are available on
both architecture;
* `load_kernel()`: manually align to `arch::layout::KERNEL_START` 2MB
for both architecture (e.g. no-op for `aarch64`);

c1f4df600f vmm: cpu_manager: massively accelerate .pause()
With 254 vCPUs, pausing now takes ~4ms instead of >254ms. This
improvement is visible when running `ch-remote pause` and is
particularly important for live migration, where every millisecond
of downtime matters.

For the wait logic, it is fine to stick to the approach of
sleeping 1ms on the first missed ACK as:

1) we have to wait anyway
2) we give time to the OS, enabling it to schedule a vCPU thread next

dd8687aebb vmm: add enum PayloadConfigError validation to improve error reporting
Currently, the following scenarios are supported by Cloud Hypervisor to
bootstrap a VM:

1. provide firmware
2. provide kernel
3. provide kernel + cmdline
4. provide kernel + initrd
5. provide kernel + cmdline + initrd

As the difference between `--firmware` and `--kernel` is not very clear
currently, especially as both use/support a Xen PVH entry, adding this
helps to identify the cause of misconfiguration.

34385e99f2 misc: simplify configure_vcpu() signature on x86_64
It is always called with topology provided, so there is no
need to pass topology as an Option. Simplifying the signature
makes further topology-related changes to arc/src/x86_64 module
simpler.

6e0403a959 misc: make topology a 4-tuple of u16s
This is the second patch in a series intended to let Cloud Hypervisor
support more than 255 vCPUs in guest VMs; the first patch/commit is
https://github.com/cloud-hypervisor/cloud-hypervisor/pull/7231

At the moment, CPU topology in Cloud Hypervisor is using
u8 for components, and somewhat inconsistently:

- struct CpuTopology in vmm/src/vm_config.rs uses four components
  (threads_per_core, cores_per_die, dies_per_package, packages);

- when passed around as a tuple, it is a 3-tuple of u8, with
  some inconsistency:

- in get_x2apic_id in arch/src/x86_64/mod.rs  the three u8
    are assumed to be (correctly)
    threads_per_core, cores_per_die, and dies_per_package, but

- in get_vcpu_topology() in vmm/src/cpu.rs the three-tuple is
    threads_per_core, cores_per_die, and packages (dies_per_package
    is assumed to always be one? not clear).

So for consistency, a 4-tuple is always passed around.

In addition, the types of the tuple components is changed from u8 to
u16, as on x86_64 subcomponents can consume up to 16 bits.

Again, config constraints have not been changed, so this patch
is mostly NOOP.
