| * Ensure pod infra containers have an exit commandMatthew Heon2020-08-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most Libpod containers are made via `pkg/specgen/generate` which includes code to generate an appropriate exit command which will handle unmounting the container's storage, cleaning up the container's network, etc. There is one notable exception: pod infra containers, which are made entirely within Libpod and do not touch pkg/specgen. As such, no cleanup process, network never cleaned up, bad things can happen. There is good news, though - it's not that difficult to add this, and it's done in this PR. Generally speaking, we don't allow passing options directly to the infra container at create time, but we do (optionally) proxy a pre-approved set of options into it when we create it. Add ExitCommand to these options, and set it at time of pod creation using the same code we use to generate exit commands for normal containers.

* / Ensure correct propagation for cgroupsv1 systemd cgroupMatthew Heon2020-08-11
|/ | | | | | | | | | | | | | | | On cgroups v1 systems, we need to mount /sys/fs/cgroup/systemd into the container. We were doing this with no explicit mount propagation tag, which means that, under some circumstances, the shared mount propagation could be chosen - which, combined with the fact that we need a mount to mask /sys/fs/cgroup/systemd/release_agent in the container, means we would leak a never-ending set of mounts under /sys/fs/cgroup/systemd/ on container restart. Fortunately, the fix is very simple - hardcode mount propagation to something that won't leak. Signed-off-by: Matthew Heon <mheon@redhat.com>
* Unconditionally retrieve pod names via APIMatthew Heon2020-08-10
| | | | | | | | | | | | | | | | | | The ListContainers API previously had a Pod parameter, which determined if pod name was returned (but, notably, not Pod ID, which was returned unconditionally). This was fairly confusing, so we decided to deprecate/remove the parameter and return it unconditionally. To do this without serious performance implications, we need to avoid expensive JSON decodes of pod configuration in the DB. The way our Bolt tables are structured, retrieving name given ID is actually quite cheap, but we did not expose this via the Libpod API. Add a new GetName API to do this.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Listing images has shown increasing performance penalties with an increasing number of images. Unless `--all` is specified, Podman will filter intermediate images. Determining intermediate images has been done by finding (and comparing!) parent images which is expensive. We had to query the storage many times which turned it into a bottleneck. Instead, create a layer tree and assign one or more images to nodes that match the images' top layer. Determining the children of an image is now exponentially faster as we already know the child images from the layer graph and the images using the same top layer, which may also be considered child images based on their history. On my system with 510 images, a rootful image list drops from 6 secs down to 0.3 secs. Also use the tree to compute parent nodes, and to filter intermediate images for pruning.

Exec for the remote API, however, has to do this inside Libpod itself, as Libpod will be directly queried (via the Inspect API for exec sessions) to get the exit code. This was done correctly when the exec session started properly, but we did not properly handle cases where the OCI runtime fails before the exec session can properly start. Making two error returns that would otherwise not set exit code actually do so should resolve the issue. Fixes #6893 Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| |/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A recent crun change stopped the creation of the container's working directory if it does not exist. This is arguably correct for user-specified directories, to protect against typos; it is definitely not correct for image WORKDIR, where the image author definitely intended for the directory to be used. This makes Podman create the working directory and chown it to container root, if it does not already exist, and only if it was specified by an image, not the user.

|/ | | | | | | | | | | | | The define package under Libpod is intended to be an extremely minimal package, including constants and very little else. However, as a result of some legacy code, it was dragging in all of libpod/image (and, less significantly, the util package). Fortunately, this was just to ensure that error constants were not duplicating, and there's nothing preventing us from importing in the other direction and keeping libpod/define free of dependencies.

* Ensure that 'rmi --force' evicts Podman containersMatthew Heon2020-07-30
| | | | | | | | | | | | | | | | | | | | | The logic for `podman rmi --force` includes a bit of code that will remove Libpod containers using Libpod's container removal logic - this ensures that they're cleanly and completely removed. For other containers (Buildah, CRI-O, etc) we fall back to manually removing the containers using the image from c/storage. Unfortunately, our logic for invoking the Podman removal function had an error, and it did not properly handle cases where we were force-removing an image with >1 name. Force-removing such images by ID guarantees their removal, not just an untag of a single name; our code for identifying whether to remove containers did not proper detect this case, so we fell through and deleted the Podman containers as storage containers, leaving traces of them in the Libpod DB.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bind-mounting /etc/passwd into the container is problematic becuase of how system utilities like `useradd` work. They want to make a copy and then rename to try to prevent breakage; this is, unfortunately, impossible when the file they want to rename is a bind mount. The current behavior is fine for read-only containers, though, because we expect useradd to fail in those cases. Instead of bind-mounting, we can edit /etc/passwd in the container's rootfs. This is kind of gross, because the change will show up in `podman diff` and similar tools, and will be included in images made by `podman commit`. However, it's a lot better than breaking important system tools. Fixes #6953 Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| | | | | | | | | | | | | | | | | | | | | | | | | | There are many use cases where you want to just mount an image without creating a container on it. For example you might want to just examine the content in an image after you pull it for security analysys. Or you might want to just use the executables on the image without running it in a container. The image is mounted readonly since we do not want people changing images.

Masking such errors is likely to report red herrings since users don't see that reading failed for some reasons but that a given event could not be found. Another race was the handler closing event channel, which could lead to two kinds of panics: double close, send to close channel. The backend takes care of that.
