223d0cf787 virtio-devices: Enable F_EVENT_IDX on control queue if negotiated 
With the VIRTIO_F_EVENT_IDX handling now conducted inside the
virtio-queue crate it is necessary to activate the functionality on
every queue if it is negotiatated. Otherwise this leads to a failure of
the guest to signal to the host that there is something in the available
queue as the queue's internal state has not been configured correctly.

Fixes: #3829

3593055e77 virtio-devices: Consider vhost-user protocol feature as acked 
For vhost-user devices, we don't want to loose the vhost-user protocol
feature through the negotiation between guest and device. Since we know
VIRTIO has no knowledge of the vhost-user protocol feature, there is no
way it would ever be acknowledged by the guest. For that reason, we
create each vhost-user device with the set of acked features containing
the vhost-user protocol feature is this one was part of the available
list.

Having the set of acked features containing this bit allows for solving
a bug that was happening through the migration process since the
vhost-user protocol feature wasn't explicitely enabled.

Implement the VIRTIO_BALLOON_F_REPORTING feature, indicating to the
guest it can report set of free pages. A new virtqueue dedicated for
receiving the information about the free pages is created. The VMM
releases the memory by punching holes with fallocate() if the guest
memory is backed by a file, and madvise() the host about the ranges of
memory that shouldn't be needed anymore.

a45e458c50 vm-migration: Add start_migration() to Migratable trait 
In order to clearly decouple when the migration is started compared to
when the dirty logging is started, we introduce a new method to the
Migratable trait. This clarifies the semantics as we don't end up using
start_dirty_log() for identifying when the migration has been started.
And similarly, we rely on the already existing complete_migration()
method to know when the migration has been ended.

A bug was reported when running a local migration with a vhost-user-net
device in server mode. The reason was because the migration_started
variable was never set to "true", since the start_dirty_log() function
was never invoked.

of the descriptor table, the available ring and used ring addresses
prior to enabling the device itself. This only applies to the case where
the device is placed behind a vIOMMU, which is the reason why the
translation is needed. Indeed, the addresses allocated by the guest are
IOVAs which must be translated into GPAs before we can access the queue.

53caa565bb virtio-devices: Add openat() syscall to seccomp filter 
When freeing memory sometimes glibc will attempt to read
"/proc/sys/vm/overcommit_memory" to find out how it should release the
blocks. This happens sporadically with Cloud Hypervisor but has been
seen in use. It is not necessary to add the read() syscall to the list
as it is already included in the virtio devices common set. Similarly
the vCPU and vmm threads already have both these in the allowed list.

85bbf75fe8 block_util: Align buffers for O_DIRECT 
Whenever the backing file of our virtio-block device is opened with
O_DIRECT, there's a requirement about the buffer address and size to be
aligned to the sector size.

We know virtio-block requests are sector aligned in terms of size, but
we must still check if the buffer address is. In case it's not, we
create an intermediate buffer that will be passed through the system
call. In case of a write operation, the content of the non-aligned
buffer must be copied beforehand, and in case of a read operation, the
content of the aligned buffer must be copied to the non-aligned one
after the operation has been completed.

Fixes #3587

0162d73ed8 virtio-queue: Update crate based on latest rust-vmm/vm-virtio 
This crate contains up to date definition of the Queue, AvailIter,
DescriptorChain and Descriptor structures forked from the upstream
crate rust-vmm/vm-virtio 27b18af01ee2d9564626e084a758a2b496d2c618.

The following patches have been applied on top of this base in order to
make it work correctly with Cloud Hypervisor requirements:

- Add MSI vector field to the Queue

  In order to help with MSI/MSI-X support, it is convenient to store the
  value of the interrupt vector inside the Queue directly.

- Handle address translations

  For devices with access to data in memory being translated, we add to
  the Queue the ability to translate the address stored in the
  descriptor.
  It is very helpful as it performs the translation right after the
  untranslated address is read from memory, avoiding any errors from
  happening from the consumer's crate perspective. It also allows the
  consumer to reduce greatly the amount of duplicated code for applying
  the translation in many different places.

- Add helpers for Queue structure

  They are meant to help crate's consumers getting/setting information
  about the Queue.

These patches can be found on the 'ch' branch from the Cloud Hypervisor
fork: https://github.com/cloud-hypervisor/vm-virtio.git

This patch takes care of updating the Cloud Hypervisor code in
virtio-devices and vm-virtio to build correctly with the latest version
of virtio-queue.

c47ab55e99 virtio-devices: Forward correct evset in vsock muxer 
When forwarding an epoll event from the unix muxer to the
targeted connection event handler, the eventset the connection
registered is forwarded instead of the actual epoll
operation (IN/OUT).

For example, if the connection was registered for EPOLLIN,
and receives an EPOLLOUT, the connection will actually handle
an EPOLLOUT.

This is the root cause of previous bug, which caused the
introduction of some workarounds (i.e: handling ewouldblock
when reading after receiving EPOLLIN, which should never happen).

When matching the connection, we retrieve and use the evset of
the connection instead of the one passed as a parameter.
The compiler does not complain for an unused variable because
it was first logged in a debug! statement.

This is an unfortunate naming mistake that caused a lot of problems.

Fixes #3497

58d25b3ccc virtio-devices: net: Improve throughput with virtio features 
By merging receive buffers through the VIRTIO_NET_F_MRG_RXBUF feature,
as well as enabling the use of indirect descriptors through
VIRTIO_RING_F_INDIRECT_DESC feature, we achieve better throughput for
the virtio-net device without hurting its latency.

cd9d1cf8fc pci, virtio-devices, vmm: Allocate PCI 64-bit bars per segment 
Since each segment must have a non-overlapping memory range associated
with it the device memory must be equally divided amongst all segments.
A new allocator is used for each segment to ensure that BARs are
allocated from the correct address ranges. This requires changes to
PciDevice::allocate/free_bars to take that allocator and when
reallocating BARs the correct allocator must be identified from the
ranges.

0249e8641a Move Cloud Hypervisor to virtio-queue crate 
Relying on the vm-virtio/virtio-queue crate from rust-vmm which has been
copied inside the Cloud Hypervisor tree, the entire codebase is moved to
the new definition of a Queue and other related structures.

The reason for this move is to follow the upstream until we get some
agreement for the patches that we need on top of that to make it
properly work with Cloud Hypervisor.

0fb24ea3ae virtio-devices: mem: Discard unplugged ranges only on activate() 
In order to support correctly the snapshot/restore and migration use
cases, we must be careful with the ranges that we discard by punching
holes. On restore, there might be some ranges already plugged in,
meaning they should not be discarded. That's why we loop over the list
of blocks to discard only the ranges that are marked as unplugged.
