When QEMU is terminated by signal 15, it deletes the PidFile.
Upon detecting that QEMU has exited, the shim executes the stopVM function.
If the PidFile is not found, the PID is set to 0.
Subsequently, the shim executes `kill -9 0`, which terminates the current process group.
This prevents any further logic from being executed, resulting in resources not being cleaned up.

add_device() now checks if QEMU is running already by checking if we have
a QMP connection. If we do a new function hotplug_device() is called
which hotplugs the device if it's a network one.
Signed-off-by: Pavel Mores <pmores@redhat.com>
With the helpers from previous commit, the actual hotplugging
implementation, though lengthy, is mostly just assembling a QMP command
to hotplug the network device backend and then doing the same for the
corresponding frontend.
Note that hotplug_network_device() takes cmdline_generator types Netdev
and DeviceVirtioNet. This is intentional and aims to take advantage of
the similarity between parameter sets needed to coldplug and hotplug
devices reuse and simplify our code. To enable using the types from qmp,
accessors were added as needed.
Signed-off-by: Pavel Mores <pmores@redhat.com>
Before adding network device hotplugging functionality itself we add
a couple of helpers in a separate commit since their functionality is
non-trivial.
To hotplug a device we need a free PCI slot. We add find_free_slot()
which can be called to obtain one. It looks for PCI bridges connected
to the root bridge and looks for an unoccupied slot on each of them. The
first found is returned to the caller. The algorithm explicitly doesn't
support any more complex bridge hierarchies since those are never produced
when coldplugging PCI bridges.
Sending netdev queue and vhost file descriptors to QEMU is slightly
involved and implemented in pass_fd(). The actual socket has to be passed
in an SCM_RIGHTS socket control message (also called ancillary data, see
man 3 cmsg) so we have to use the msghdr structure and sendmsg() call
(see man 2 sendmsg) to send the message. Since qapi-rs doesn't support
sending messages with ancillary data we have to do the sending sort of
"under it", manually, by retrieving qapi-rs's socket and using it directly.

NetworkConfig::index has been used to generate an id for a network device

Network device hotplugging will use the same infrastructure (Netdev,
DeviceVirtioNet) as coldplugging, i.e. QemuCmdLine. To make the code

At least one PCI bridge is necessary to hotplug PCI devices. We only
support PCI (at this point at least) since that's what the go runtime
does (note that looking at the code in virtcontainers it might seem that
other bus types are supported, however when the bridge objects are passed
to govmm, all but PCI bridges are actually ignored). The entire logic of
bridge setup is lifted from runtime-go for compatibility's sake.

This change technically affects the path for enabled guest selinux as well,
however since this is not implemented in runtime-rs anyway nothing should
break. When guest selinux support is added this change will come handy.
Signed-off-by: Pavel Mores <pmores@redhat.com>
If guest selinux is off the runtime has to ensure that container OCI spec
contains no selinux labels for the container rootfs and process. Failure
to do so causes kata agent to try and apply the labels which fails since
selinux is not enabled in guest, which in turn causes container launch
to fail.
This is largely inspired by golang runtime(*) with a slight deviation
in ordering of checks. This change simply checks the disable_guest_selinux
config setting and if it's true it clears both rootfs and process label if
necessary. Golang runtime, on the other hand, seems to first check if
process label is non-empty and only then it checks the config setting,
meaning that if process label is empty the rootfs label is not reset
even if it's non-empty. Frankly, this looks like a potential bug though
probably unlikely to manifest since it can be assumed that the labels are
either both empty, or both non-empty.

kata-shim was not reporting `inactive_file` in memory stat.
This memory is deducted by containerd when calculating the size of container working set, as it can be paged out by the operating
system under memory pressure. Without reporting `inactive_file`, containerd will over report container memory usage.
[Here](https://github.com/containerd/containerd/blob/v1.7.22/pkg/cri/server/container_stats_list_linux.go#L117) is where containerd
deducts `inactive_file` from memory usage.
Note that kata-shim correctly reports `total_inactive_file` for cgroup v1, but this was not implemented for cgroup v2.
This commit:
- Adds code in kata-shim to report "inactive_file" memory for cgroup v2
- Implements reporting of all available cgroup v2 memory stats to containerd
- Uses defensive coding to avoid assuming existence of any memory.stat fields

Some container images are configured such that the user (and group)

For example, in a Dockerfile, one might write:
> USER 185

Some images, however, might have:
> RUN groupadd --system --gid=185 spark
> RUN useradd --system --uid=185 --gid=spark spark
> ...
> USER spark
indicating that the UID:GID pair should be resolved at runtime via
/etc/passwd.
To handle such images correctly, read through all /etc/passwd files in
all layers, find the latest version of it (i.e., the top-most layer with
such a file), and, in so doing, ensure that whiteouts of this file are
respected (i.e., if one layer adds the file and some subsequent layer

Our code for handling images being pulled inside the guest relies on a
containerType ("sandbox" or "container") being set as part of the
container annotations, which is done by the CRI Engine being used, and
depending on the used CRI Engine we check for a specfic annotation
related to the image-name, which is then passed to the agent.
However, when running kata-containers without kubernetes, specifically
when using `nerdctl`, none of those annotations are set at all.
One thing that we can do to allow folks to use `nerdctl`, however, is to
take advantage of the `--label` flag, and document on our side that
users must pass `io.kubernetes.cri.image-name=$image_name` as part of
the label.
By doing this, and changing our "fallback" so we can always look for
such annotation, we ensure that nerdctl will work when using the nydus
snapshotter, with kata-containers, to perform image pulling inside the

1. Use the new value of AllowRequestsFailingPolicy after setting up a
new Policy. Before this change, the only way to enable
AllowRequestsFailingPolicy was to change the default Policy file,
built into the Guest rootfs image.
2. Ignore errors returned by regorus while evaluating Policy rules, if
AllowRequestsFailingPolicy was enabled. For example, trying to
evaluate the UpdateInterfaceRequest rules using a policy that didn't
define any UpdateInterfaceRequest rules results in a "not found"
error from regorus. Allow AllowRequestsFailingPolicy := true to
bypass that error.
3. Add simple CI test for AllowRequestsFailingPolicy.
These changes are restoring functionality that was broken recently by
commmit df23eb09a6.

Since we can't find a homogeneous value for the resource/cgroup
management of multiple hypervisors, and we have decoupled the
env vars in the Makefile, we don't need the generic ones.

To avoid overriding env vars when multiple hypervisors are
available, we add per-hypervisor vars for static resource
management and cgroups handling. We reflect that in the
relevant config files as well.

It's better to check the container's status before
try to send signal to it. Since there's no need
to send signal to it when the container's stopped.

Since stop sandbox would be called in multi path,
thus it's better to set and check the sandbox's state.

Generate policy that validates each exec command line argument, instead
of joining those args and validating the resulting string. Joining the
args ignored the fact that some of the args might include space
characters.
The older format from genpolicy-settings.json was similar to:
"ExecProcessRequest": {
"commands": [
"sh -c cat /proc/self/status"
],
"regex": []
},
That format will not be supported anymore. genpolicy will detect if its
users are trying to use the older "commands" field and will exit with
a relevant error message in that case.
The new settings format is:
"ExecProcessRequest": {
"allowed_commands": [
[
"sh",
"-c",
"cat /proc/self/status"
]
],
"regex": []
},

It's time to delete the kata oci spec implemented just
for kata. As we have already done align OCI Spec with
oci-spec-rs.

This commit aligns the OCI Spec implementation in runtime-rs
with the OCI Spec definitions and related operations provided
by oci-spec-rs. Key changes as below:
(1) Leveraged oci-spec-rs to align Kata Runtime OCI Spec with
the official OCI Spec.
(2) Introduced runtime-spec to separate OCI Spec definitions
from Kata-specific State data structures.
(3) Preserved the original code logic and implementation as
much as possible.
(4) Made minor code adjustments to adhere to Rust programming
conventions;

This commit aligns the OCI Spec used within agent-ctl
with the oci-spec-rs definition and operations. This
enhancement ensures that agent-ctl adheres to the latest
OCI standards and provides a more consistent and reliable
experience for managing container images and configurations.

This commit transitions the data implementation for OCI Spec
from kata-oci-spec to oci-spec-rs. While both libraries adhere
to the OCI Spec standard, significant implementation details
differ. To ensure data exchange through TTRPC services, this
commit reimplements necessary data conversion logic.
This conversion bridges the gap between oci-spec-rs data and
TTRPC data formats, guaranteeing consistent and reliable data
transfer across the system.
