| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Basic theory: We remove the container, but *only from the DB*. We leave it in c/storage, we leave the lock allocated, we leave it running (if it is). Then we create an identical container with an altered name, and add that back to the database. Theoretically we now have a renamed container. The advantage of this approach is that it doesn't just apply to rename - we can use this to make *any* configuration change to a container that does not alter its container ID. Potential problems are numerous. This process is *THOROUGHLY* non-atomic at present - if you `kill -9` Podman mid-rename things will be in a bad place, for example. Also, we can't rename containers that can't be removed normally - IE, containers with dependencies (pod infra containers, for example). The largest potential improvement will be to move the majority of the work into the DB, with a `RecreateContainer()` method - that will add atomicity, and let us remove the container without worrying about depencies and similar issues. Potential problems: long-running processes that edit the DB and may have an older version of the configuration around. Most notable example is `podman run --rm` - the removal command needed to be manually edited to avoid this one. This begins to get at the heart of me not wanting to do this in the first place... This provides CLI and API implementations for frontend, but no tunnel implementation. It will be added in a future release (just held back for time now - we need this in 3.0 and are running low on time). This is honestly kind of horrifying, but I think it will work.

|\ \ | |/ |/| Initial implementation of volume plugins
| * Add tests for volume pluginsMatthew Heon2021-01-14
| | | | | | | | | | | | | | | | | | This involves a new test binary (a basic implementation of the volume plugin protocol) and a new image on quay.io (Containerfile to produce it and all sources located in this commit). The image is used to run a containerized plugin we can test against. Signed-off-by: Matthew Heon <mheon@redhat.com>
| * Initial implementation of volume pluginsMatthew Heon2021-01-14
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This implements support for mounting and unmounting volumes backed by volume plugins. Support for actually retrieving plugins requires a pull request to land in containers.conf and then that to be vendored, and as such is not yet ready. Given this, this code is only compile tested. However, the code for everything past retrieving the plugin has been written - there is support for creating, removing, mounting, and unmounting volumes, which should allow full functionality once the c/common PR is merged. A major change is the signature of the MountPoint function for volumes, which now, by necessity, returns an error. Named volumes managed by a plugin do not have a mountpoint we control; instead, it is managed entirely by the plugin. As such, we need to cache the path in the DB, and calls to retrieve it now need to access the DB (and may fail as such). Notably absent is support for SELinux relabelling and chowning these volumes. Given that we don't manage the mountpoint for these volumes, I am extremely reluctant to try and modify it - we could easily break the plugin trying to chown or relabel it. Also, we had no less than *5* separate implementations of inspecting a volume floating around in pkg/infra/abi and pkg/api/handlers/libpod. And none of them used volume.Inspect(), the only correct way of inspecting volumes. Remove them all and consolidate to using the correct way. Compat API is likely still doing things the wrong way, but that is an issue for another day. Fixes #4304 Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| * | container stop: release lock before calling the runtimeValentin Rothberg2021-01-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Podman defers stopping the container to the runtime, which can take some time. Keeping the lock while waiting for the runtime to complete the stop procedure, prevents other commands from acquiring the lock as shown in #8501. To improve the user experience, release the lock before invoking the runtime, and re-acquire the lock when the runtime is finished. Also introduce an intermediate "stopping" to properly distinguish from "stopped" containers etc. Fixes: #8501 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

Thus, indicating to users that the place to debug should be in the security attributes of the container. When creating a container with a SELinux label that doesn't exist, we get a fairly cryptic error message: ``` $ podman run --security-opt label=type:my_container.process -it fedora bash Error: OCI runtime error: write file `/proc/thread-self/attr/exec`: Invalid argument ``` This instead handles any errors coming from LSM's `/proc` API and enhances the error message with a relevant indicator that it's related to the container's security attributes. A sample run looks as follows: ``` $ bin/podman run --security-opt label=type:my_container.process -it fedora bash Error: `/proc/thread-self/attr/exec`: OCI runtime error: unable to assign security attribute ``` With `debug` log level enabled it would be: ``` Error: write file `/proc/thread-self/attr/exec`: Invalid argument: OCI runtime error: unable to assign security attribute ``` Note that these errors wrap ErrOCIRuntime, so it's still possible to to compare these errors with `errors.Is/errors.As`. One advantage of this approach is that we could start handling these errors in a more efficient manner in the future. e.g. If a SELinux label doesn't exist (yet), we could retry until it becomes available.
