This is not intended to be used to support `--filter` or similar on the
CLIs list yet, it's solely to clean up our rather awkward use of
`ContainerClient.list()` today in the CLI. The list RPC simply returns
all of the containers we have created. Because of this, for a LOT of our
commands we filter to what we need client side, which feels like a
waste.. This change introduces a filter struct that we can provide an
array of container IDs, labels, and the status of the containers to
filter the `list()` output from.
This additionally, because it was killing (pun not intended) me and I
was already having to change this area for the `list()` additions,
changes container kill slightly to return an error if you try and kill a
container that doesn't exist.
`make test` occasionally fails with:
```
✘ Test testHostDNSReinitialize() recorded an issue at HostDNSResolverTest.swift:132:45: Expectation failed: (error →
Error Domain=NSPOSIXErrorDomain Code=2 "No such file or directory") as? (ContainerizationError → NSError)
✘ Suite HostDNSResolverTest failed after 0.119 seconds with 1 issue.

- Implemented the TODO at
ContainerAPIService/Client/Utility.swift:358 — warn the
user when a named volume is auto-created.
- This only triggers for named volumes (not anonymous
ones), matching Docker's behavior of informing users
about implicit resource creation.

- Closes#1150.
- The problem seems to be that the selinux label attribute enforcement
doesn't play well with overlayfs.
- Solution is to set the `lsm` boot line argument. The new value
corresponds to what one would see in a Lima VM with Colima. The Kata
kernel we use doesn't provide any of those modules, so now if you run
`dmesg | grep -i lsm` in a container you will just see: `LSM:
initializing lsm=capability`
Send the hash of entire tar file in the first BuildTransfer packet to
prevent container-builder-shim from using stale cached contents.
This PR resolves#1143.
This PR relies on apple/container-builder-shim#64.
## Type of Change
- [X] Bug fix
- [ ] New feature
- [ ] Breaking change
- [ ] Documentation update
## Motivation and Context
Current container-builder-shim uses only first few bytes of tar file as
checksum, which leads to the usage of stale cached contents if the
change of build context is not included in the first bytes of tar file.

- Bump `containerization` to `0.25.0`
- Updates for parameter changes on containerization
registry access API.
- Updates for change to containerization
`cleanUpOrphanedBlobs` function.
ClientContainer was honestly extremely awkward. It could only be created
by passing either a ContainerConfiguration, or a Snapshot that had to be
obtained from calling a static method on the type itself. The type also
did not store a connection, so every single method got a new xpc
connection to the APIServer. This change aims to rework this type to be
just a generic client, that is *not* a client for one specific
container, but for any.
- Rename to ContainerClient
- Have list() return [ContainerSnapshot]
- Create a connection in the constructor
- Change all the callsites to use the new API
- Small, somewhat related, change to logs API in the APIServer. Now that
we don't need to call get() to grab a client anymore which was typically
what did "does this container exist" logic and gave a nice error
message, I added a small check in the APIServer to see if the container
exists and return mostly the same error message.
- Closes#1122.
- Adds placeholder ManagedResource and unit tests. Nothing is using
these yet.
- Adds system-defined resource labels for owning plugin and resource
role. The system discriminates the builtin network using role "builtin".
- Adds builtin role when creating builtin network at startup, and
ensures that a preexisting network with ID "default" gets updated with
the role label.
- Replace all network ID checks for "default" with the builtin role
check.
- Adds "builder" role to builder VM.

## Summary
The `reload()` method in `PacketFilter.swift` references
`/sbin/reloadProcess` (the local variable name) instead of
`/sbin/pfctl`. This causes all DNS create and delete operations to fail:
```
Error: internalError: "pfctl reload exec failed: "Error Domain=NSCocoaErrorDomain Code=4 "The file "reloadProcess" doesn't exist.""
```
## Fix
One-line change: `/sbin/reloadProcess` → `/sbin/pfctl`
## Testing
Verified on macOS 26 (Tahoe) with Apple Silicon:
- `sudo container system dns create test.sdc.internal --localhost
203.0.113.1` succeeds without error
- Container can resolve and reach host services through the DNS redirect
- Closes#1113.
- This is the newest we can do until we address #767.
- Slight change to PacketFilter error handling so unit tests work more
reliably.
- Try making CLINetworkTests serialized to see if parallel execution is
causing flakes.
- Refer to #862
- Updated `SIZE` field to `FULL SIZE`, as it seemed more appropriate so
it does not get mixed up with the `descriptor size` field
- Closes#860
- Fixed#892.
- By contrast with `rm`, `prune` should display
the amount of reclaimed storage, so added code
to retrieve it.

- Closes#977.
- Closes#1058.
- Prevents unexpected removal of containers on
bootstrapping and starting failures, by reorganizing
error handling for container `run`, `start`, and
`exec` so that error handling only unwinds that
which was done in the current scope.
- Relies on apple/containerization#495.
- Closes#1037.
- Adds a `--mode` flag that has `nat` and `hostOnly` options.
The host-only option selects the vmnet host-only mode,
where containers attached to the network can reach each
other and the host, but not external systems.
- Closes#346.
- This PR enables connecting host's localhost ports from
containers.
- It adds an option `--localhost <localhost>` to DNS
create command, after which the packets heading
ip address in container are redirected to localhost in
host machine. Packet filter rule is added and deleted
along with the creation and deletion of localhost domain.
This change adds --dns parameter support to the build command, matching
the existing functionality in the run command. This allows users to
specify custom DNS nameservers (like Google DNS 8.8.8.8) when building
container images, which is essential when the host machine uses a local
DNS resolver (e.g., 127.0.0.2) that doesn't work inside containers.
Changes:
- Added --dns option to BuildCommand to accept DNS nameserver IP
addresses
- Modified build logic to detect DNS configuration changes and recreate
the builder container when DNS settings differ
- Passed DNS configuration to BuilderStart.start() method
- Updated builder container creation to use specified DNS nameservers or
fall back to network gateway

- Facilitates #507, #642.
- Plumb logger with logger option access into every command.
- StderrLogHandler allows logging to be enhanced for ANSI color mode for
log levels, JSONL log output, replacing `--debug` with `--level level`.
- Global logger is now just an Application.swift fileprivate only used
for initial args processing.
- Log with timestamp at debug and trace level.
- Metadata output is crude at present; we can refine this in a
follow-up.

Closes https://github.com/apple/container/issues/1050
If the sandbox svc exits out of band of the usual stop (or regular exit)
case the container svc's state is not properly updated for the
container. This was due to the cleanup steps involving trying to send
the shutdown rpc which cannot succeed as the sandbox svc does not exist
to service it.
To handle this, let's treat shutdown not returning successfully as
non-fatal (as this is mostly best effort), log an error and continue the
state cleanup.
- Update image load and build to handle rejected paths during tar
extraction. For the image load command there is now a `--force` function
that fails extractions with rejected paths when false, and just warns
about the rejected paths when true.
- Update `container stats` for statistics API properties now all being
optional.

- Adds `aarch64` as an alias for `arm64` in the `Arch` enum. This
addresses the maintainer's request to support this common architecture
name, ensuring consistency with `x86_64` normalization and preventing
failures for users expecting `aarch64` support.
- The container fails to start with a generic "permission denied"
error when attempting to publish privileged ports (ports below
1024) without root privileges. This provides a confusing user
experience as the error doesn't explain why permission was
denied.
- Closes#1005.
- Adapt everything to use MACAddress type from containerization 0.20.0.
- Allocate MAC addresses for every container so that we have
deterministic IPv6 link local addresses.
- Add AAAA handling to ContainerDNSHandler.
- NOTE: Only works on Tahoe. On Sequoia, we don't have a good way to set
or determine the IPv6 network prefix when networks are created, so we
can't infer the IPv6 link local addresses for AAAA responses and we
instead return `NODATA`.
- Closes#461.
- Extract core types into ContainerResources target.
- Extract ContainerNetworkServiceClient from ContainerNetworkService.
- Relocate sandbox client from ContainerClient to
ContainerSandboxServiceClient.
- Relocate ContainerClient to ContainerAPIServiceClient.

Fixes#833.
Currently, when stopping and immediately restarting a container, it would fail with the error:
`“container expected to be in created state, got: shuttingDown”` and then be automatically deleted.
The `SandboxService` process waits five seconds before exiting after shutdown. During this interval, a rapid restart could reconnect to the still-terminating process in the `shuttingDown` state, triggering a state validation error.
This fix forcefully terminates the `SandboxService` process with `SIGKILL` upon container exit, instead of waiting five seconds. The bootstrap now defensively checks for and cleans up any stale services before registering new ones, preventing reconnections to processes in the `shuttingDown` state.

- With CZ release 0.17.0, the IP and CIDR address
types changed from String to IPv4Address and
CIDRv4, respectively. This PR applies the corresponding
adaptations to container.
- Refactor the `volume prune` command to follow a client-side approach.
The `volumeDiskUsage` is calculated in the service file, so it made
sense to leave that there.
- Relates to the discussion from #914
- Fixes#925.
- When the API service enumerates creation dates, the configuration
value from the network helper is used instead of the persistent config
value, so the creation date winds up being the current time. The short
term fix is for the API server to return NetworkState values that
combine the API server's persistent network config with the network
status returned from the helper.
- The longer term refinement could be to define a uniform model for
resources where each resource type has Metadata (id/Identifiable,
creationDate, labels), and type-specific configuration and state/status.

Previously `container image prune` called `ImageStore.prune()` (renamed
to `cleanupOrphanedBlobs()` in cz 0.15.0) which only removed orphaned
content blobs and never actually removed images.
This PR fixes that behavior so `container image prune` removes dangling
images by default, and with `-a` removes all unused images, not just
dangling ones.

## Motivation and Context
This PR implements the `container system df` command to display disk
usage statistics for images, containers, and volumes, along with their
total count, active count, size, and reclaimable space for each resource
type.
Active resources are determined by container mount references and
running state, while reclaimable space is calculated from inactive or
stopped resources.
Example output:
```
~/container ❯ container system df
TYPE TOTAL ACTIVE SIZE RECLAIMABLE
Images 4 3 4.42 GB 516.5 MB (11%)
Containers 4 2 2.69 GB 1.51 GB (56%)
Local Volumes 3 2 208.5 MB 66.2 MB (32%)
```
I'll have some follow-on PRs that will add `-v/--verbose` flag for
detailed per-resource information, `--filter` flag for filtering output
by resource type, and a `--debug` flag for debug statistics like block
usage, clone counts etc.
