77ee331be0 resources: Enable KASLR in kernel config 
This option improves the security of the guest by randomising the start
address of the kernel in physical memory. We should turn this on so as
to ensure all our functionality such as memory hotplug and kernel
loading works as this is an option used widely in production.

d2f1749edb vmm: config: Add poll_queue property to DiskConfig 
Recently, vhost_user_block gained the ability of actively polling the
queue, a feature that can be disabled with the poll_queue property.

This change adds this property to DiskConfig, so it can be used
through the "disk" argument.

For the moment, it can only be used when vhost_user=true, but this
will change once virtio-block gets the poll_queue feature too.

4ebf01b344 vhost_user_backend: Don't report out socket broken errors 
This is a perfectly acceptable situation as it causes the backend to
exit because the VMM has closed the connection. This addresses the
rather ugly reporting of errors from the backend that appears
interleaved with the output from the VMM.

ed1e7817cc vmm: Workaround double reboot triggered by the kernel 
The kernel does not adhere to the ACPI specification (probably to work
around broken hardware) and rather than busy looping after requesting an
ACPI reset it will attempt to reset by other mechanisms (such as i8042
reset.)

In order to trigger a reset the devices write to an EventFd (called
reset_evt.) This is used by the VMM to identify if a reset is requested
and make the VM reboot. As the reset_evt is part of the VMM and reused
for both the old and new VM it is possible for the newly booted VM to
immediately get reset as there is an old event sitting in the EventFd.

The simplest solution is to "drain" the reset_evt EventFd on reboot to
make sure that there is no spurious events in the EventFd.

5c06b7f862 vhost_user_block: Implement optional static polling 
Actively polling the virtqueue significantly reduces the latency of
each I/O operation, at the expense of using more CPU time. This
features is specially useful when using low-latency devices (SSD,
NVMe) as the backend.

This change implements static polling. When a request arrives after
being idle, vhost_user_block will keep checking the virtqueue for new
requests, until POLL_QUEUE_US (50us) has passed without finding one.

POLL_QUEUE_US is defined to be 50us, based on the current latency of
enterprise SSDs (< 30us) and the overhead of the emulation.

This feature is enabled by default, and can be disabled by using the
"poll_queue" parameter of "block-backend".

This is a test using null_blk as a backend for the image, with the
following parameters:

 - null_blk gb=20 nr_devices=1 irqmode=2 completion_nsec=0 no_sched=1

0e4e27ea9d vhost_user_block: Make use of the EVENT_IDX feature 
Now that vhost_user_backend and vm-virtio do support EVENT_IDX, use it

It can be clearly appreciated how the number of vm exits per second,
specially the ones related to notifications (kvm_fast_mmio and
kvm_msi_set_irq) is drastically lower.

d17fa784bc vm-virtio: Implement support for EVENT_IDX 
VIRTIO_RING_F_EVENT_IDX is a virtio feature that allows to avoid
device <-> driver notifications under some circunstances, most
notably when actively polling the queue.

This commit implements support for in in the vm-virtio
crate. Consumers of this crate will also need to add support for it by
exposing the feature and calling using update_avail_event() and
get_used_event() accordingly.

793d4e7b8d vmm: Move codebase to GuestMemoryAtomic from vm-memory 
Relying on the latest vm-memory version, including the freshly
introduced structure GuestMemoryAtomic, this patch replaces every
occurrence of Arc<ArcSwap<GuestMemoryMmap> with
GuestMemoryAtomic<GuestMemoryMmap>.

The point is to rely on the common RCU-like implementation from
vm-memory so that we don't have to do it from Cloud-Hypervisor.

ddf6caf955 ci: Improve test_memory_mergeable_on stability 
The integration test test_memory_mergeable_on has been fairly unstable
for quite some time now. Because it can take some time for the VM to be
spawned and to be able to perform a correct measure of the PSS, this
commit simply increases the time before such measure is done.
This should return more accurate PSS results, which should help
stabilize the test.

3f09eff6c5 vhost_user_fs: add fs cache request operations 
This introduces setupmapping and removemapping methods to server.rs,
passthrough.rs and filesystem.rs in order to support virtiofs dax mode
inside guest.

Since we don't really want the server.rs to know that it is dealing with
vhost-user specifically, this is making it more generic by adding a new
trait which has three functions map()/unmap()/sync() corresponding to
fs_slave_{map, unmap, sync}, server.rs will take anything that implements
the trait.

be78c6da49 vhost_rs: Fix unit test race condition 
The unit tests are run from cargo test through multiple threads of the
same process. For this reason, all these threads share their file
descriptors (because that's how this works on Linux), which means that
any of them can close a file descriptor opened from another thread.

In the context of create_listener() and accept_connection() tests, they
can run concurrently and this generates some failure when the file
descriptor create_listener() is binding to is being closed from the
accept_connection() test.

In order to avoid such race condition, this patch simply removes the
part of the unit test performing an explicit and unsafe file descriptor
closure.

3edc2bd6ab vmm: Prevent memory overcommitment through virtio-fs shared regions 
When a virtio-fs device is created with a dedicated shared region, by
default the region should be mapped as PROT_NONE so that no pages can be
faulted in.

It's only when the guest performs the mount of the virtiofs filesystem
that we can expect the VMM, on behalf of the backend, to perform some
new mappings in the reserved shared window, using PROT_READ and/or
PROT_WRITE.
