mount_source_cpath is the root of the paths used a storage mount

service address is determined after the initial secure image build.

Let me explain why:
In our previous approach, we implemented guest pull by passing PullImageRequest to the guest.
However, this method resulted in the loss of specifications essential for running the container,
such as commands specified in YAML, during the CreateContainer stage. To address this,
it is necessary to integrate the OCI specifications and process information
from the image’s configuration with the container in guest pull.
The snapshotter method does not care this issue. Nevertheless, a problem arises
when two containers in the same pod attempt to pull the same image, like InitContainer.
This is because the image service searches for the existing configuration,
which resides in the guest. The configuration, associated with <image name, cid>,
is stored in the directory /run/kata-containers/<cid>. Consequently, when the InitContainer finishes
its task and terminates, the directory ceases to exist. As a result, during the creation
of the application container, the OCI spec and process information cannot
be merged due to the absence of the expected configuration file.

Currently, the image is pulled by image-rs in the guest and mounted at
`/run/kata-containers/image/cid/rootfs`. Finally, the agent rebinds
`/run/kata-containers/image/cid/rootfs` to `/run/kata-containers/cid/rootfs` in CreateContainer.
However, this process requires specific cleanup steps for these mount points.
To simplify, we reuse the mount point `/run/kata-containers/cid/rootfs`
and allow image-rs to directly mount the image there, eliminating the need for rebinding.

This commit extends the vfio-ap hotplug test to include the use of `zcrypttest`.

- ioctl_test
- simple_test
- simple_one_thread_test
- simple_multi_threads_test
- multi_thread_stress_test
- hang_after_offline_online_test
A writable root filesystem is required for testing because the reference count
needs to be reset after each test round. The current containerd kata containers
support does not include `--privileged_without_host_devices`, which is necessary
to configure a writable filesystem along with `--privileged`. (Please check out
https://github.com/kata-containers/kata-containers/issues/9791 for details)

Since Hypervisor::stop_vm() is called from the WaitProcess request handling
which appears to be per-container, it can be called multiple times during
kata pod shutdown. Currently the function errors out on any subsequent
call after the initial one since there's no VM to stop anymore. This
commit makes the function tolerate that condition.
While it seems conceivable that sandbox shouldn't be stopped by WaitProcess
handling, and the right fix would then have to happen elsewhere, this
commit at least makes qemu driver's behaviour consistent with other
hypervisor drivers in runtime-rs.
We also slightly improve the error message in case there's no
QemuInner::qemu_process instance.

A configuration option `guest_component_procs` has been introduced that
indicates which guest component processes are supposed to be spawned by
the agent. The default behaviour remains that all of those processes are
actively spawned by the agent. At the moment this is based on presence
of binaries in the rootfs and the guest_component_api_rest option.
The new option is incremental:
none -> attestation-agent -> confidential-data-hub -> api-server-rest
e.g. api-server-rest implies attestation-agent and confidential-data-hub
the `none` option has been removed from guest_component_api_rest, since
this is addresses by the introduced option.
To not change expected behaviour for non-coco guests we still will still
only attempt to spawn the processes if the requested attestation binaries
are present on the rootfs, and issue in warning in those cases.

This is needed, as b1710ee2c0 made the
default agent shipped the one with policy support. However, we simply
didn't update the rootfs to reflect that, causing then an issue to start
the agent as shown by the strace below:
```
open("/etc/kata-opa/default-policy.rego", O_RDONLY|O_LARGEFILE|O_CLOEXEC) = -1 ENOENT (No such file or directory)
futex(0x7f401eba0c28, FUTEX_WAKE_PRIVATE, 1) = 1
rt_sigprocmask(SIG_BLOCK, ~[RTMIN RT_1 RT_2], [], 8) = 0
tkill(553681, SIGABRT) = 0
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
--- SIGABRT {si_signo=SIGABRT, si_code=SI_TKILL, si_pid=553681, si_uid=1000} ---
+++ killed by SIGABRT (core dumped) +++
```
This happens as the default policy **must** be set when the agent is
built with policy support, but the code path that copies that into the
rootfs is only triggered if the rootfs itself is built with
AGENT_POLICY=yes, which we're now doing for both confidential and
non-confidential cases.
Sadly this was not caught by CI till we the cache was not used for
rootfs, which should be solved by the previous commit.

By default, when a container is created with the `--privileged` flag,
all devices in `/dev` from the host are mounted into the guest. If
there is a block device(e.g. `/dev/dm`) followed by a generic
device(e.g. `/dev/null`)，two identical block devices(`/dev/dm`)
would be requested to the kata agent causing the agent to exit with error:
> Conflicting device updates for /dev/dm-2
As the generic device type does not hit any cases defined in `switch`，
the variable `kataDevice` which is defined outside of the loop is still
the value of the previous block device rather than `nil`. Defining `kataDevice`
in the loop fixes this bug.

In linux, when a FIFO is opened and there are no writers, the reader
will continuously receive the HUP event. This can be problematic.
To avoid this problem, we open stdin in write mode and keep the stdin-writer
We need to open the stdout/stderr as the read mode and keep the open endpoint
until the process is delete. otherwise,
the process would exit before the containerd side open and read
the stdout fifo, thus runD would write all of the stdout contents into
the stdout fifo and then closed the write endpoint. Then, containerd
open the stdout fifo and try to read, since the write side had closed,
thus containerd would block on the read forever.
Here we keep the stdout/stderr read endpoint File in the common_process,
which would be destroied when containerd send the delete rpc call,
at this time the containerd had waited the stdout read return, thus it
can make sure the contents in the stdout/stderr fifo wouldn't be lost.

## Kata security objective
Kata seeks to prevent an untrusted container workload or user of that container workload to gain
control of, obtain information from, or tamper with the host infrastructure.

## Background on containers, layered security
Traditional containers leverage several key Linux kernel features to provide isolation and
a view that the container workload is the only entity running on the host. Key features include
`Namespaces`, `cgroups`, `capablities`, `SELinux` and `seccomp`. The canonical runtime for creating such
a container is `runc`. In the remainder of the document, the term `traditional-container` will be used
to describe a container workload created by runc.

Kata Containers provides a second layer of isolation on top of those provided by traditional-containers.
The hardware virtualization interface is the basis of this additional layer. Kata launches a lightweight
virtual machine, and uses the guest’s Linux kernel to create a container workload, or workloads in the case
of multi-container pods. In Kubernetes and in the Kata implementation, the sandbox is carried out at the
pod level. In Kata, this sandbox is created using a virtual machine.

an OCI based runtime, such as Kata Containers. Typical CRI implementors are `cri-o` and `containerd`.

In order to run a container inside of the Kata sandbox, several virtual machine devices and interfaces
are required. Kata translates sandbox and container definitions to underlying virtualization technologies provided
by a set of virtual machine monitors (VMMs) and hypervisors. These devices and their underlying
implementations are discussed in detail in the following section.

## Interface to the Kata sandbox/virtual machine
In case of Kata, today the devices which we need in the guest are:
- Storage: In the current design of Kata Containers, we are reliant on the CRI implementor to
assist in image handling and volume management on the host. As a result, we need to support a way of passing to the sandbox the container rootfs, volumes requested
by the workload, and any other volumes created to facilitate sharing of secrets and `configmaps` with the containers. Depending on how these are managed, a block based device or file-system
sharing is required. Kata Containers does this by way of `virtio-blk` and/or `virtio-fs`.
- Networking: A method for enabling network connectivity with the workload is required. Typically this will be done providing a `TAP` device
to the VMM, and this will be exposed to the guest as a `virtio-net` device. It is feasible to pass in a NIC device directly, in which case `VFIO` is leveraged
and the device itself will be exposed to the guest.
-Control: In order to interact with the guest agent and retrieve `STDIO` from containers, a medium of communication is required.
This is available via `virtio-vsock`.
- Devices: `VFIO` is utilized when devices are passed directly to the virtual machine and exposed to the container.
- Dynamic Resource Management: `ACPI` is utilized to allow for dynamic VM resource management (for example: CPU, memory, device hotplug). This is required when containers are resized,
or more generally when containers are added to a pod.

How these devices are utilized varies depending on the VMM utilized. We clarify the default settings provided when integrating Kata
with the QEMU, Firecracker and Cloud Hypervisor VMMs in the following sections.

### Virtual Machine Monitor(s)
In a KVM/QEMU (any other VMM utilizing KVM) virtualization setup, all virtual
machines (VMs) share the same host kernel. This shared environment can lead to
scenarios where one VM could potentially impact the performance or stability of
other VMs, including the possibility of a Denial of Service attack.
- Kernel Vulnerabilities: Since all VMs rely on the host's kernel, a
vulnerability in the kernel could be exploited by a process running within one
VM to affect the entire system. This could lead to scenarios where the
compromised VM impacts other VMs or even takes down the host.
- Improper Isolation and Containment: If the virtualization environment is not
correctly configured, processes in one VM might impact other VMs. This could
occur through improper isolation of network traffic, shared file systems, or
other inter-VM communication channels.
- Hypervisor Vulnerabilities: Flaws in the KVM hypervisor or QEMU could be
exploited to cause information disclosure, data tampering, elevation of
privileges, denial of service, and others. Since KVM/QEMU leverages the host
kernel for its operation, any exploit at this level can have widespread impacts.
- Malicious or Flawed Guest Operating Systems: A guest operating system that is
maliciously designed or has serious flaws could engage in activities that
disrupt the normal operation of the host or other guests. This might include
aggressive network activity or interactions with the virtualization stack that
lead to instability.
- Resource Exhaustion: A VM could consume excessive shared resources such as
CPU, memory, or I/O bandwidth, leading to resource starvation for other VMs.
This could be due to misconfiguration, a runaway process, or a deliberate
denial of service attack from a compromised VM.
### Devices
Each virtio device is implemented by a backend, which may execute within userspace on the host (vhost-user), the VMM itself, or within the host kernel (vhost). While it may provide enhanced performance,
vhost devices are often seen as higher risk since an exploit would be already running within the kernel space. While VMM and vhost-user are both in userspace on the host, `vhost-user` generally allows for the back-end process to require less system calls and capabilities compared to a full VMM.

#### `virtio-fs`
`virtio-fs` is supported in Cloud Hypervisor and QEMU. `virtio-fs`'s interaction with the host filesystem is done through a vhost-user daemon, `virtiofsd`.
The `virtio-fs` client, running in the guest, will generate requests to access files. `virtiofsd` will receive requests, open the file, and request the VMM
to `mmap` it into the guest. When DAX is utilized, the guest will access the host's page cache, avoiding the need for copy and duplication. DAX is still an experimental feature,
and is not enabled by default.

From the `virtiofsd` [documentation](https://gitlab.com/virtio-fs/virtiofsd/-/blob/main/README.md):
```This program must be run as the root user. Upon startup the program will switch into a new file system namespace with the shared directory tree as its root. This prevents “file system escapes” due to symlinks and other file system objects that might lead to files outside the shared directory. The program also sandboxes itself using seccomp(2) to prevent ptrace(2) and other vectors that could allow an attacker to compromise the system after gaining control of the virtiofsd process.```
DAX-less support for `virtio-fs` is available as of the 5.4 Linux kernel. QEMU VMM supports virtio-fs as of v4.2. Cloud Hypervisor
supports `virtio-fs`.

- Device Isolation Failure: One of the primary risks associated with VFIO is the
failure to isolate the physical device. If a VM can affect the operation of the
physical device in a way that impacts other VMs or the host system, it could
lead to security breaches or system instability.
- DMA Attacks: Direct Memory Access (DMA) attacks are a significant concern with
VFIO. Since the device has direct access to the system's memory, there's a risk
that a compromised VM could use its assigned device to read or write memory
outside of its allocated space, potentially accessing sensitive information or
affecting the host or other VMs.
- Firmware Vulnerabilities: Devices attached via VFIO rely on their firmware,
which can have vulnerabilities. A compromised device firmware could be exploited
to gain unauthorized access or to disrupt the system. Resource Starvation:
Improperly managed, a VM with direct access to hardware resources could
monopolize those resources, leading to performance degradation or denial of
service for other VMs or the host system.
- Escalation of Privileges: If a VM with VFIO access is compromised, it could
potentially be used to gain higher privileges than intended, especially if the
I/O devices have capabilities that are not adequately controlled or monitored.
- Improper Configuration and Management: Human errors in configuring VFIO, such
as incorrect group or user permissions, can expose the system to risks.
Additionally, inadequate monitoring and management of the VMs and their devices
can lead to security lapses.
- Software Vulnerabilities: Like any software, the components of VFIO (like the
kernel modules, device drivers, and management tools) can have vulnerabilities
that might be exploited by an attacker to compromise the security of the system.
Inter-VM Interference and Side-Channel Attacks: Even with device assignment,
there could be side-channel attacks where an attacker VM infers sensitive
information from the physical device's behavior or through shared resources like
cache.
#### ACPI (Dragonball uses Upcall)
ACPI is necessary for hotplugging of CPU, memory and devices. ACPI is available
in QEMU and Cloud Hypervisor. Device, CPU and memory hotplug are not available
in Firecracker.
- Hypervisor Vulnerabilities: In virtualized environments, the hypervisor
manages ACPI calls for virtual machines (VMs). If the hypervisor has
vulnerabilities in handling ACPI requests, it could lead to escalated privileges
or other security breaches.
- VM Escape: A sophisticated attack could exploit ACPI functionality to achieve
a VM escape, where malicious code in a VM breaks out to the host system or other
VMs. Firmware Attacks in a Virtualized Context: Similar to physical
environments, firmware-based attacks (including those targeting ACPI) in
virtualized systems can be persistent and difficult to detect. In a virtualized
environment, such attacks might not only compromise the host system but also all
the VMs running on it.
- Resource Starvation Attacks: ACPI functionality could be exploited to
manipulate power management features, causing denial of service through
resource starvation. For example, an attacker could force a VM into a low-power
state, degrading its performance or availability.
- Compromised VMs Affecting Host ACPI Settings: If a VM is compromised, it might
be used to alter ACPI settings on the host, affecting all VMs on that host. This
could lead to various impacts, from performance degradation to system
instability.
- Supply Chain Risks: As with non-virtualized environments, the firmware,
including ACPI firmware used in virtualized environments, could be compromised
during the supply chain process, leading to vulnerabilities that affect all VMs
running on the hardware.
