If a hypervisor debug console is enabled and sandbox_cgroup_only is set,
the hypervisor can fail to open /dev/ptmx, which prevents the sandbox
from launching.
This is caused by the absence of a device cgroup entry to allow access
to /dev/ptmx. When sandbox_cgroup_only is not set, the hypervisor
inherits the default unrestrcited device cgroup, but with it enabled it
runs into allow / deny list restrictions.
Fix by adding an allowlist entry for /dev/ptmx when debug is enabled,
sandbox_cgroup_only is true, and no /dev/ptmx is already in the list of
devices.

This PR is a continuing work for (kata-containers#3679).

Fixes: kata-containers#3678
Signed-off-by: Hyounggyu Choi <Hyounggyu.Choi@ibm.com>
Initial VFIO-AP support (#578) was simple, but somewhat hacky; a
different code path would be chosen for performing the hotplug, and
agent-side device handling was bound to knowing the assigned queue
numbers (APQNs) through some other means; plus the code for awaiting
them was written for the Go agent and never released. This code also
artificially increased the hotplug timeout to wait for the (relatively
expensive, thus limited to 5 seconds at the quickest) AP rescan, which
is impractical for e.g. common k8s timeouts.
Since then, the general handling logic was improved (#1190), but it
assumed PCI in several places.
In the runtime, introduce and parse AP devices. Annotate them as such
when passing to the agent, and include information about the associated
APQNs.
The agent awaits the passed APQNs through uevents and triggers a
rescan directly.

- VFIOPciDeviceMediatedType() can simply fulfill the device addition based
on a type categorized by GetVFIODeviceType()

In some cases, network endpoints will be configured through Prestart
Hook. So network endpoints may need to be added(hotpluged) after vm
is started and also Prestart Hook is executed.
We move pre-start hook functions' execution to sandbox_start to allow
hooks running between vm_start and netns_scan easily, so that the
lifecycle API can be cleaner.

According to the runtime OCI Spec, there can be some hook
operations in the lifecycle of the container. In these hook
operations, the runtime can execute some commands. There are different
points in time in the container lifecycle and different hook types
can be executed.
In this commit, we are now supporting 4 types of hooks(same in
runtime-go): Prestart hook, CreateRuntime hook, Poststart hook and
Poststop hook.

The logic to decide which cgroup driver is used is currently based on the
cgroup path that the host provides. This requires host and guest to use the
same cgroup driver. If the guest uses kata-agent as init, then systemd can't be
used as the cgroup driver. If the host requests a systemd cgroup, this
currently results in a rustjail panic:

The QEMU log file is essentially about fine grain tracing of QEMU
internals and mostly useful for developpers, not production. Notably,
the log file isn't limited in size, nor rotated in any way. It means
that a container running in the VM could possibly flood the log file
with a guest triggerable trace. For example, on openshift, the log
file is supposed to reside on a per-VM 14 GiB tmpfs mount. This means
that each pod running with the kata runtime could potentially consume
this amount of host RAM which is not acceptable.
Error messages are best collected from QEMU's stderr as kata is doing
now since PR #5736 was merged. Drop support for the QEMU log file
because it doesn't bring any value but can certainly do harm.

QEMU has always been started daemonized since the beginning. I
could not find any justification for that though, but it certainly
introduces a problem : QEMU stops logging errors when started this
way, which isn't accaptable from a support standpoint. The QEMU
community discourages the use of -daemonize ; mostly because
libvirt, QEMU's primary consummer, doesn't use this option and
prefers getting errors from QEMU's stderr through a pipe in order
to enforce rollover.
Now that virtcontainers knows how to start QEMU with a pre-
established QMP connection, let's start QEMU without -daemonize.
This requires to handle the reaping of QEMU when it terminates.
Since cmd.Wait() is blocking, call it from a goroutine.
Signed-off-by: Greg Kurz <groug@kaod.org>
LaunchCustomQemu() currently starts QEMU with cmd.Run() which is
supposed to block until the child process terminates. This assumes
that QEMU daemonizes itself, otherwise LaunchCustomQemu() would
block forever. The virtcontainers package indeed enables the
Daemonize knob in the configuration but having such an implicit
dependency on a supposedly configurable setting is ugly and fragile.
cmd.Run() is :
func (c *Cmd) Run() error {
if err := c.Start(); err != nil {
return err
}
return c.Wait()
}
Let's open-code this : govmm calls cmd.Start() and returns the
cmd to virtcontainers which calls cmd.Wait().
If QEMU doesn't start, e.g. missing binary, there won't be any
errors to collect from QEMU output. Just drop these lines in govmm.
Similarily there won't be any log file to read from in virtcontainers.
Drop that as well.

Running QEMU daemonized ensures that the QMP socket is ready to
accept connections when LaunchQemu() returns. In order to be
able to run QEMU undaemonized, let's handle that part upfront.
Create a listener socket and connect to it. Pass the listener
to QEMU and pass the connected socket to QMP : this ensures
that we cannot fail to establish QMP connection and that we
can detect if QEMU exits before accepting the connection.
This is basically what libvirt does.

QEMU's -qmp option can be passed the file descriptor of a socket that
is already in listening mode. This is done with by passing `fd=XXX`
to `-qmp` instead of a path. Note that these two options are mutually
exclusive : QEMU errors out if both are passed, so we check that as
well in the validation function.
While here add the `path=` stanza in the path based case for clarity.

When QEMU is launched daemonized, we have the guarantee that the

Augment the mock hypervisor so that we can validate that ACPI memory hotplug
is carried out as expected.
We'll augment the number of memory slots in the hypervisor config each

that large memory hotplugs are broken up into appropriately sized
pieces in the unit test.
Signed-off-by: Eric Ernst <eric_ernst@apple.com>
If we're using ACPI hotplug for memory, there's a limitation on the
amount of memory which can be hotplugged at a single time.
During hotplug, we'll allocate memory for the memmap for each page,
resulting in a 64 byte per 4KiB page allocation. As an example, hotplugging 12GiB
of memory requires ~192 MiB of *free* memory, which is about the limit
we should expect for an idle 256 MiB guest (conservative heuristic of 75%
of provided memory).
From experimentation, at pod creation time we can reliably add 48 times
what is provided to the guest. (a factor of 48 results in using 75% of
provided memory for hotplug). Using prior example of a guest with 256Mi
RAM, 256 Mi * 48 = 12 Gi; 12GiB is upper end of what we should expect
can be hotplugged successfully into the guest.
Note: It isn't expected that we'll need to hotplug large amounts of RAM
after workloads have already started -- container additions are expected
to occur first in pod lifecycle. Based on this, we expect that provided
memory should be freely available for hotplug.
If virtio-mem is being utilized, there isn't such a limitation - we can
hotplug the max allowed memory at a single time.

When booting the TDX kernel with `tdx_disable_filter`, as it's been done

Whether this will be part of the upstream kernel or not is a different

DMA API, making these devices compatible with TDX.

To make cgroup v1 and v2 works well, I use `cgroups::cgroup` in
`Container` to manager cgroup now. `CgroupManager` in rustjail has some
drawbacks. Frist, methods in Manager traits are not visiable. So we need
to modify rustjail and make them public. Second, CgrupManager.cgroup is
private too, and it can't be serialized. We can't load/save it in
status file. One solution is adding getter/setter in rustjail, then
create `cgroup` and set it when loading status. In order to keep the
modifications to a minimum in rustjail, I use `cgroups::cgroup`
directly. Now it can work on cgroup v1 or v2, since cgroup-rs do this
stuff.

To plug drop-in support into existing config-loading code in a robust
way, more specifically to create a single point where this needs to be
handled, load_from_file() and load_raw_from_file() were refactored.
Seeing as the original implemenations of both functions were identical
apart from adjust_config() calls in load_from_file(), load_from_file()
was reimplemented in terms of load_raw_from_file().

The central function being added here is load() which takes a path to a
base config file and uses it to load the base config file itself, find
the corresponding drop-in directory (get_dropin_dir_path()), iterate
through its contents (update_from_dropins()) and load each drop-in in
turn and merge its contents with the base file (update_from_dropin()).
Also added is a test of load() which mirrors the corresponding test in
the golang runtime (TestLoadDropInConfiguration() in config_test.go).

This is the core functionality of merging config file fragments into the
base config file. Our TOML parser crate doesn't seem to allow working
at the level of TomlConfig instances like BurntSushi, used in the Golang
runtime, does so we implement the required functionality at the level of
toml::Value trees.
Tests to verify basic requirements are included. Values set by a base
config file and not touched by a subsequent drop-in should be preserved.
Drop-in config file fragments should be able to change values set by the
base config file and add settings not present in the base. Conversion
of a merged tree into a mock TomlConfig-style structure is tested as
well.

`exec` will execute a command inside a container which exists and is not
frozon or stopped. *Inside* means that the new process share namespaces
and cgroup with the container init process. Command can be specified by
`--process` parameter to read from a file, or from other parameters such
as arg, env, etc. In order to be compatible with `create`/`run`
commands, I refactor libcontainer. `Container` in builder.rs is divided
into `InitContainer` and `ActivatedContainer`. `InitContainer` is used
for `create`/`run` command. It will load spec from given bundle path.
`ActivatedContainer` is used by `exec` command, and will read the
container's status file, which stores the spec and `CreateOpt` for
creating the rustjail::LinuxContainer. Adapt the spec by replacing the
process with given options and updating the namesapces with some paths
to join the container. I also rename the `ContainerContext` as
`ContainerLauncher`, which is only used to spawn process now. It uses
the `LinuxContaier` in rustjail as the runner. For `create`/`run`, the
`launch` method will create a new container and run the first process.
For `exec`, the `launch` method will spawn a process which joins a
container.

The `is_signal_handled` function determine which signal the container
process has been handled. But currently `is_signal_handled` is only
catching (SigCgt). While the container process is ignoring (SigIgn) or
blocking (SigBlk) also should not be converted from the `SIGTERM` to
`SIGKILL`. For example, when using terminationGracePeriodSeconds the k8s
will send SIGTERM first and then send `SIGKILL`, in this case, the
container ignores the `SIGTERM`, so we should send the `SIGTERM` not the
`SIGKILL` to the container.

updateFromDropIn() uses the infrastructure built by previous commits to
ensure no contents of 'tomlConfig' are lost during decoding. To do
this, we preserve the current contents of our tomlConfig in a clone and
decode a drop-in into the original. At this point, the original
instance is updated but its Agent and/or Hypervisor fields are
potentially damaged.
To merge, we update the clone's Agent/Hypervisor from the original
instance. Now the clone has the desired Agent/Hypervisor and the
original instance has the rest, so to finish, we just need to move the
clone's Agent/Hypervisor to the original.

These functions take a TOML key - an array of individual components,

two 'tomlConfig' instances. They copy the value of the struct field
identified by the key from the source instance to the target one if
necessary.
This is only done if the TOML key points to structures stored in
maps by 'tomlConfig', i.e. 'hypervisor' and 'agent'. Nothing needs to

Similar to network, we can use multiple queues for virtio-block
devices. This can help improve storage performance.
This commit changes the number of queues for block devices to
the number of cpus for cloud-hypervisor and qemu.
Today the default number of cpus a VM starts with is 1.
Hence the queues used will be 1. This change will help
improve performance when the default cold-plugged cpus is greater
than one by changing this in the config file. This may also help
when we use the sandboxing feature with k8s that passes down
the sum of the resources required down to Kata.

We want to have the file descriptors of the opened tuntap device to pass
them down to the VMMs, so the VMMs don't have to explicitly open a new
tuntap device themselves, as the `container_kvm_t` label does not allow
such a thing.
With this change we ensure that what's currently done when using QEMU as
the hypervisor, can be easily replicated with other VMMs, even if they
don't support multiqueue.
As a side effect of this, we need to close the received file descriptors
in the code of the VMMs which are not going to use them.

Adding FFI_NO_PI to the netlink flags causes no harm to the supported
and tested hypervisors as when opening the device by its name Cloud
Hypervisor[0], Firecracker[1], and QEMU[2] do set the flag already.
However, when receiving the file descriptor of an opened tutap device
Cloud Hypervisor is not able to set the flag, leaving the guest without
connectivity.
To avoid such an issue, let's simply add the FFI_NO_PI flag to the
netlink flags and ensure, from our side, that the VMMs don't have to set
it on their side when dealing with an already opened tuntap device.
Note that there's a PR opened[3] just for testing that this change
doesn't cause any breakage.

Some annotations are used to override hypervisor configurations, and you
know it's dangerous. We must be careful when overriding hypervisor configuration
by annotations, to avoid security flaws.
There are two existing mechanisms to prevent attacks by annotations:
1) config.hypervisor.enable_annotations defines the allowed annotation
keys for config.hypervisor.
2) config.hyperisor.xxxx_paths defines allowd values for specific keys.
The access methods for config.hypervisor.xxx enforces the permisstion
checks for above rules.
To update conifg, traverse the annotation hashmap,check if the key is enabled in hypervisor or not.
If it is enabled. For path related annotation, check whether it is valid or not
before updating conifg. For cpu and memory related annotation, check whether it
is more than or less than the limitation for DB and qemu beforing updating config.
If it is not enabled, there will be three possibilities, agent related
annotation, runtime related annotation and hypervisor related annotation
but not enabled. The function will handle agent and runtime annotation
first, then the option left will be the invlaid hypervisor, err message
will be returned.

The TomlConfig structure is a parsed form of Kata configuration file,
but it's a little inconveneient to access those configuration
information directly. So introduce a wrapper KataConfig to easily
access those configuration information.
Two singletons of KataConfig is provided:
- KATA_DEFAULT_CONFIG: the original version directly loaded from Kata
configuration file.
- KATA_ACTIVE_CONFIG: the active version is the KATA_DEFAULT_CONFIG
patched by annotations.
So the recommended to way to use these two singletons:
- Load TomlConfig from configuration file and set it as the default one.
- Clone the default one and patch it with values from annotations.
- Use the default one for permission checks, such as to check for
allowed annotation keys/values.
- The patched version may be set as the active one or passed to clients.
- The clients directly accesses information from the active/passed one,
and do not need to check annotation for override.

Since #902 the `io.katacontainers.config.hypervisor` pod annotations
have only been permitted if explicitly allowed in the global
configuration. The default global configuration allows no such
annotations. That's important because several of those annotations
would cause Kata to execute arbitrary binaries, and so were wildly
unsafe.
However, this is inconvenient for the
`io.katacontainers.config.hypervisor.enable_iommu` annotation
specifically, which controls whether the sandbox VM includes a vIOMMU.
A guest side vIOMMU is necessary to implement VFIO passthrough devices
with `vfio_mode = vfio`, so enabling that mode of operation currently
requires a global configuration change, and can't just be enabled
per-pod.
Unlike some of the other hypervisor annotations, the `enable_iommu`
annotation is quite safe. By default the vIOMMU is not present, so
allowing a user to override it for a pod only improves their
facilities for isolation. Even if the global default were changed to
enable the vIOMMU, that doesn't compel the guest kernel to use it, so
allowing a user to disable the vIOMMU doesn't materially affect
isolation either.
Therefore, allow the io.katacontainers.config.hypervisor.enable_iommu
annotation to work in the default configurations.

This commit enables runk to handle `root.path` in `config.json`
properly even if the path is specified by a relative path that
includes the single (`.`) or the double (`..`) dots.
For example, with a bundle at `/to/bundle` and a rootfs directly
under `/to/bundle` such as `/to/bundle/{bin,dev,etc,home,...}`,
the `root.path` value can be either `/to/bundle` or just `.`.
This behavior conforms to OCI runtime spec.
Accordingly, a bundle path managed by runk's status file
(`status.json`) always is statically stored as a canonical path.
Previously, a bundle path has been got by `oci_state()` of rustjail's
API that returns the path as the parent directory path of a rootfs
(`root.path`). In case of the kata-agent, this works properly because
the kata containers assume that the rootfs path is always
`/to/bundle/rootfs`. However in case of standard OCI runtimes,
a rootfs can be placed anywhere under a bundle, so the rootfs path
doesn't always have to be at a `/to/bundle/rootfs`.

This release has been tracked through the v24.0 project.
virtio-iommu specification describes how a device can be attached by default
to a bypass domain. This feature is particularly helpful for booting a VM with
guest software which doesn't support virtio-iommu but still need to access
the device. Now that Cloud Hypervisor supports this feature, it can boot a VM
with Rust Hypervisor Firmware or OVMF even if the virtio-block device exposing
the disk image is placed behind a virtual IOMMU.
Multiple checks have been added to the code to prevent devices with identical
identifiers from being created, and therefore avoid unexpected behaviors at boot
or whenever a device was hot plugged into the VM.
Sparse mmap support has been added to both VFIO and vfio-user devices. This
allows the device regions that are not fully mappable to be partially mapped.
And the more a device region can be mapped into the guest address space, the
fewer VM exits will be generated when this device is accessed. This directly
impacts the performance related to this device.
A new serial_number option has been added to --platform, allowing a user to
set a specific serial number for the platform. This number is exposed to the
guest through the SMBIOS.

go-test.sh changes behaviour based on both the $CI and $KATA_DEV_MODE
variables, but not in a way that makes a lot of sense.
If either one is set it uses the test_coverage path, instead of the
test_local path. That collects coverage information, as the name
suggests, but it also means it runs the tests twice as root and
non-root, which is very non-obvious.
It's not clear what use case the test_local path is for at all.
Developer local builds will typically have $KATA_DEV_MODE set and CI
builds will have $CI set. There's essentially no downside to running
coverage all the time - it has little impact on the test runtime.
In addition, if *both* $CI and $KATA_DEV_MODE are set, the script
refuses to run things as root, considering it "unsafe". While having
both set might be unwise in a general sense, there's not really any
way running sudo can be any more unsafe than it is with either one
set.
So, simplify everything by just always running the test_coverage path.
This leaves the test_local path unused, so we can remove it entirely.

go-test.sh defaults to testing all the packages listed by go list, except
for a number filtered out. It turns out that none of those filters are
necessary any more:
* We've long required a Go newer than 1.9 which means the vendor filter
isn't needed
* The agent filter doesn't do anything now that we've moved to the Kata
2.x unified repo
* The tests filters don't hit anything on the list of modules in
src/runtime (which is the only user of the script)
But since we don't need to filter anything out any more, we don't even need
to iterate through a list ourselves. We can simply pass "./..." directly
to go test and it will iterate through all the sub-packages itself.
Interestingly this more than doubles the speed of "make test" for me - I
suspect because go test's internal paralellism works better over a larger
pool of tests.
This also lets us remove handling of non-existent coverage files from
test_go_package(), since with default options we will no longer test packages without tests
by default. If the user explicitly requests testing of a package with no
tests, then failing makes sense.

The go-test.sh script has an explicit chmod command, run as root, to
set the mode of the temporary coverage files to 0644. AFAICT the
point of this is specifically the 004 bit allowing world read access,
so that we can then merge the temporary coverage file into the main
coverage file.
That's a convoluted way of doing things. Instead we can just run the tail
command which reads the temporary file as the same user that generated it.
In addition, go-test.sh became root to remove that temporary coverage
file. This is not necessary, since deleting a regular file just requires
write access to the directory, not the file itself.

The html-coverage option to this script doesn't really alter behaviour
it just does the same thing as normal coverage, then converts the
report to HTML. That conversion is a single command, plus a chmod to
make the final output mode 0644. That overrides any umask the user
has set, which doesn't seem like a policy decision this script should
be making.
Nothing in the kata-containers or tests repository uses this, so it doesn't
really make sense to keep this logic inside this script.

We're currently hitting a race condition on the Cloud Hypervisor's
driver code when quickly removing and adding a block device.
This happens because the device removal is an asynchronous operation,
and we currently do *not* monitor events coming from Cloud Hypervisor to
know when the device was actually removed. Together with this, the
sandbox code doesn't know about that and when a new device is attached
it'll quickly assign what may be the very same ID to the new device,
leading to the Cloud Hypervisor's driver trying to hotplug a device with
the very same ID of the device that was not yet removed.
This is, in a nutshell, why the tests with Cloud Hypervisor and
devmapper have been failing every now and then.
The workaround taken to solve the issue is basically *not* passing down
the device ID to Cloud Hypervisor and simply letting Cloud Hypervisor
itself generate those, as Cloud Hypervisor does it in a manner that
avoids such conflicts. With this addition we have then to keep a map of
the device ID and the Cloud Hypervisor's generated ID, so we can
properly remove the device.
This workaround will probably stay for a while, at least till someone
has enough cycles to implement a way to watch the device removal event
and then properly act on that. Spoiler alert, this will be a complex
change that may not even be worth it considering the race can be avoided
with this commit.

Unbreak the `agent-ctl` tool connecting to the agent with a Unix domain
socket.
It appears that [1] changed the behaviour of connecting to the agent
using a local Unix socket (which is not used by Kata under normal
operation).
The change can be seen by reverting to commit
72b8144b56 (the one before [1]) and
running the agent manually as:
```bash
$ sudo KATA_AGENT_SERVER_ADDR=unix:///tmp/foo.socket target/x86_64-unknown-linux-musl/release/kata-agent
```
Before [1], in another terminal we see this:
```bash
$ sudo lsof -U 2>/dev/null |grep foo|awk '{print $9}'
@/tmp/foo.socket@
```
But now, we see the following:
```bash
$ sudo lsof -U 2>/dev/null |grep foo|awk '{print $9}'
@/tmp/foo.socket
```
Note the last byte which represents a nul (`\0`) value.
The `agent-ctl` tool used to add that trailing nul but now it seems to not
be needed, so this change removes it, restoring functionality. No
external changes are necessary so the `agent-ctl` tool can connect to
the agent as below like this:
```bash
$ cargo run -- -l debug connect --server-address "unix://@/tmp/foo.socket" --bundle-dir "$bundle_dir" -c Check -c GetGuestDetails

which have to be added so we can expose I/O throttling configurations to

Cloud Hypervisor exposes a single MaxRate to be used for both inbound

Currently EnableMockTesting() takes no arguments and will always place the
mock storage in the fixed location /tmp/vc/mockfs. This means that one
test run can interfere with the next one if anything isn't cleaned up
(and there are other bugs which means that happens). If if those were
fixed this would allow developers testing on the same machine to interfere
with each other.
So, allow the mockfs to be placed at an arbitrary place given as a

existing temporary directory, so we don't need any additional cleanup just

There are several tests in mount_test.go which perform a sample bind
mount. These need a corresponding unmount to clean up afterwards or
attempting to delete the temporary files will fail due to the existing
mountpoint. Most of them had such an unmount, but
TestBindMountInvalidPgtypes was missing one.
In addition, the existing unmounts where done inconsistently - one was
simply inline (so wouldn't be executed if the test fails too early) and one
is a defer. Change them all to use the t.Cleanup mechanism.
For the dummy mountpoint files, rather than cleaning them up after the
test, the tests were removing them at the beginning of the test. That
stops the test being messed up by a previous run, but messily. Since
these are created in a private temporary directory anyway, if there's
something already there, that indicates a problem we shouldn't ignore.
In fact we don't need to explicitly remove these at all - they'll be
removed along with the rest of the private temporary directory.

kata-monitor allows to get data profiles from the kata shim

(e.g., http://$NODE_ADDRESS:8090/debug/pprof/?sandbox=$MYSANDBOXID).
In order to proxy the requests and the responses to the right shim,

The profiling index page proxied by kata-monitor contains the link to all

accessed through kata-monitor.
This happens because the profiling index page comes from the kata shim,

Running unit tests should generally have minimal dependencies on
things outside the build tree. It *definitely* shouldn't modify
system wide things outside the build tree. Currently the runtime
"make test" target does so, though.
Several of the tests in src/runtime/pkg/katautils/hook_test.go require a
sample hook binary. They expect this hook in
/usr/bin/virtcontainers/bin/test/hook, so the makefile, as root, installs
the test binary to that location.
Go tests automatically run within the package's directory though, so
there's no need to use a system wide path. We can use a relative path to
the binary build within the tree just as easily.

If, for some reason, we're able to launch cloud hypervisor but not able

kata-containers/pulls#3771 added TDX support for Cloud Hypervisor, but
two big things got overlooked while doing that.
1. virtio-fs, as of now, cannot be part of the trust boundary, so the
Confidential Guest will not be using it.
2. virtio-block hotplug should be enabled in order to use virtio-block
for the rootfs (used with the devmapper plugin).
When trying to use cloud-hypervisor with TDX using virtio-fs, we're
facing the following error on the guest kernel:
```
virtiofs virtio2: device must provide VIRTIO_F_ACCESS_PLATFORM
```
After checking and double-checking with virtiofs and cloud-hypervisor
developers, it happens as confidential containers might put some
limitations on the device, so it can't access all of the guests' memory
and that's where this restriction seems to be coming from. Vivek
mentioned that virtiofsd do not support VIRTIO_F_ACCESS_PLATFORM (aka
VIRTIO_F_IOMMU_PLATFORM) yet, and that for ecrypted guests virtiofs may
not be the best solution at the moment.
@sboeuf put this in a very nice way: "if the virtio-fs driver doesn't
support VIRTIO_F_ACCESS_PLATFORM, then the pages corresponding to the
virtqueues and the buffers won't be marked as SHARED, meaning the VMM
won't have access to it".
Interestingly enough, it works with QEMU, and it may be due to some
change done on the patched QEMU that @devimc is packaging, but we won't
take the path to figure out what was the change and patch
cloud-hypervisor on the same way, because of 1.

The OCI spec is very specific about it:
"The prestart hooks MUST be executed in the runtime namespace."
Signed-off-by: Samuel Ortiz <s.ortiz@apple.com>
That allows us to amend those annotations with information that could be
used when running those hooks.
For example nerdctl will use those annotations to resolve the networking
namespace path in where to run the CNI plugin, i.e. the created pod
networking namespace.

This feature was introduced a year ago or so by Hanna Reitz as part of

In commit 78dff468bf1 we introduced logic to rewrite PCIDEVICE_ environment
variables for the container so that they contain correct addresses for the
Kata VM rather than for the host. Unfortunately, we never actually invoked
the function to do this.
It turns out we need to do this not only at container creation time, but
also for environment variables supplied to processes exec-ed into the
container after creation (e.g. with crictl exec). Add calls to make both
those updates.

add_devices() generates a mapping of host to guest PCI addresses which is
used to update some environment variables for the workload. Currently it
just does this locally, but it turns out we're going to need the same map
again in order to correct environment variables for processes exec-ed into
the existing container.
Move the map to the sandbox structure so we can keep it around for those
later uses.

This function updates PCIDEVICE_ environment variables (such as those
supplied by the Kubernetes SR-IOV plugin) in the OCI spec to be correct
for the Kata VM, rather than for the host.
We neglected to actually call this function, however, and it turns out that
when we do, we need to do things slightly different. We actually need to
adjust envionment variables both in the OCI spec when creating a container
and also in the variables supplied for exec-ing a new process within an
existing container.
Adjust the function so that it can be used for both these cases.

We are converting the Network structure into an interface, so that

There are software and hardware architectures which do not support
dynamically adjusting the CPU and memory resources associated with a
sandbox. For these, today, they rely on "default CPU" and "default
memory" configuration options for the runtime, either set by annotation
or by the configuration toml on disk.
In the case of a single container (launched by ctr, or something like
"docker run"), we could allow for sizing the VM correctly, since all of
the information is already available to us at creation time.
In the sandbox / pod container case, it is possible for the upper layer
container runtime (ie, containerd or crio) could send a specific
annotation indicating the total workload resource requirements
associated with the sandbox creation request.
In the case of sizing information not being provided, we will follow
same behavior as today: start the VM with (just) the default CPU/memory.
If this information is provided, we'll track this as Workload specific
resources, and track default sizing information as Base resources. We
will update the hypervisor configuration to utilize Base+Workload
resources, thus starting the VM with the appropriate amount of CPU and
memory.
In this scenario (we start the VM with the "right" amount of
CPU/Memory), we do not want to update the VM resources when containers
are added, or adjusted in size.
This functionality is introduced behind a configuration flag,
`static_sandbox_resource_mgmt`. This is defaulted to false for all
configurations except Firecracker, which is set to true.
This'll greatly improve UX for folks who are utilizing
Kata with a VMM or hardware architecture that doesn't support hotplug.
Note, users will still be unable to do in place vertical pod autoscaling
or other dynamic container/pod sizing with this enabled.

Add the POD metadata we get from the container manager to the metrics by

Fixes: #3551
Signed-off-by: Francesco Giudici <fgiudici@redhat.com>
Kata-monitor detects started and terminated kata pods by monitoring the
vc/sbs fs (this makes sense since we will have to access that path to
access the sockets there to get the metrics from the shim).
While kata-monitor updates its sandbox cache based on the sbs fs events,
it will schedule also a sync with the container manager via the CRI in
order to sync the list of sandboxes there.
The container manager will be the ultimate source of truth, so we will
stick with the response from the container manager, removing the
sandboxes not reported from the container manager.
May happen anyway that when we check the container manager, the new kata
pod is not reported yet, and we will remove it from the kata-monitor pod
cache. If we don't get any new kata pod added or removed, we will not
check with the container manager again, missing reporting metrics about
that kata pod.
Let's stick with the sbs fs as the source of truth: we will update the
cache just following what happens on the sbs fs.
At this point we may have also decided to drop the container manager
connection... better instead to keep it in order to get the kube pod
metadata from it, i.e., the kube UID, Name and Namespace associated with
the sandbox.
Every time we get a new sandbox from the sbs fs we will try to retrieve the
pod metadata associated with it.
Right now we just attach the container manager sandbox id as a label to
the exposed metrics, making hard to link the metrics to the running pod
in the kubernetes cluster.
With kubernetes pod metadata we will be able to add them as labels to map
explicitly the metrics to the kubernetes workloads.
