* libpod: Factor out usage of unix.MNT_DETACH from (*Volume).unmountDoug Rabson2022-09-27
| | | | | | | | | | | There is an existing wrapper for unix.Unmount(..., MNT_DETACH) in util_linux.go but that filters all errors and for volumes, we only want to filter EINVAL. The existing libpod.Unmount seems to only have one call site so perhaps these can be merged. [NO NEW TESTS NEEDED] Signed-off-by: Doug Rabson <dfr@rabson.org>

* auto-update: validate container imageValentin Rothberg2022-09-26
| | | | | | | | | | | Auto updates using the "registry" policy require container to be created with a fully-qualified image reference. Short names are not supported due the ambiguity of their source registry. Initially, container creation errored out for non FQN images but it seems that Podman has regressed.

* | Add support for 'image' volume driverMatthew Heon2022-09-22
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | We added the concept of image volumes in 2.2.0, to support inspecting an image from within a container. However, this is a strictly read-only mount, with no modification allowed. By contrast, the new `image` volume driver creates a c/storage container as its underlying storage, so we have a read/write layer. This, in and of itself, is not especially interesting, but what it will enable in the future is. If we add a new command to allow these image volumes to be committed, we can now distribute volumes - and changes to them - via a standard OCI image registry (which is rather new and quite exciting). Future work in this area: - Add support for `podman volume push` (commit volume changes and push resulting image to OCI registry). - Add support for `podman volume pull` (currently, we require that the image a volume is created from be already pulled; it would be simpler if we had a dedicated command that did the pull and made a volume from it) - Add support for scratch images (make an empty image on demand to use as the base of the volume) - Add UOR support to `podman volume push` and `podman volume pull` to enable both with non-image volume drivers Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Don't mount /dev/tty* inside privileged containers running systemdDan Čermák2022-09-22
| | | | | | | | | | | | | | According to https://systemd.io/CONTAINER_INTERFACE/, systemd will try take control over /dev/ttyN if exported, which can cause conflicts with the host's tty in privileged containers. Thus we will not expose these to privileged containers in systemd mode, as this is a bad idea according to systemd's maintainers. Additionally, this commit adds a bats regression test to check that no /dev/ttyN are present in a privileged container in systemd mode This fixes https://github.com/containers/podman/issues/15878 Signed-off-by: Dan Čermák <dcermak@suse.com>

|\ | | | | Introduce graph-based pod container removal
| * Introduce graph-based pod container removalMatthew Heon2022-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally, during pod removal, we locked every container in the pod at once, did a number of validity checks to ensure everything was safe, and then removed all the containers in the pod. A deadlock was recently discovered with this approach. In brief, we cannot lock the entire pod (or much more than a single container at a time) without causing a deadlock. As such, we converted to an approach where we just looped over each container in the pod, removing them individually. Unfortunately, this removed a lot of the validity checking of the earlier approach, allowing for a lot of unintended bad things. Infra containers could be removed while containers in the pod still depended on them, for example. There's no easy way to do validity checks while in a simple loop, so I implemented a version of our graph-traversal logic that currently handles pod start. This version acts in the reverse order of startup: startup starts from containers which depend on nothing and moves outwards, while removal acts on containers which have nothing depend on them and moves inwards. By doing graph traversal, we can guarantee that nothing is removed while something that depends on it still exists - so the infra container should be the last thing in a pod that is removed, for example. In the (unlikely) case that a graph of the pod's containers cannot be built (most likely impossible without database editing) the old method of pod removal has been retained to ensure that even misbehaving pods can be forcibly evicted from the state. I'm fairly confident that this resolves the problem, but there are a lot of assumptions around dependency structure built into the original pod removal code and I am not 100% sure I have captured all of them.

| * | Ensure that a broken OCI spec does not break inspectMatthew Heon2022-09-14
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The process of saving the OCI spec is not particularly reboot-safe. Normally, this doesn't matter, because we recreate the spec every time a container starts, but if one was to reboot (or SIGKILL, or otherwise fatally interrupt) Podman in the middle of writing the spec to disk, we can end up with a malformed spec that sticks around until the container is next started. Some Podman commands want to read the latest version of the spec off disk (to get information only populated after a container is started), and will break in the case that a partially populated spec is present. Swap to just ignoring these errors (with a logged warning, to let folks know something went wrong) so we don't break important commands like `podman inspect` in these cases.

* | events: Fix spelling of newNullEventerDoug Rabson2022-09-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This function changed from public to private which broke the FreeBSD build. Sadly, adding FreeBSD to the cross build isn't currently possible since github.com/godbus/dbus relies on cgo on FreeBSD. I've tried to fix this upstream but my PR is going nowhere - I think this dependency is only needed for systemd which isn't a thing on FreeBSD so it might be possible to work around the problem in libpod by making the systemd code conditional on linux.

The problem is that we are using the journal accessors wrong. There is no need to call GetCursor() and compare them manually. The Next() return an integer which tells if it moved to the next or not. This means the we can remove GetCursor() which would fail when there is no entry. This also includes another bug fix. Previously the logic called Next() twice for the first entry which caused us to miss the first entry. To reproduce this issue you can run the following commands: ``` sudo journalctl --rotate sudo journalctl --vacuum-time=1s ``` Note that this will delete the full journal. Now run podman events and it fails but with this patch it works. Now generate a single event, i.e. podman pull alpine, and run podman events --until 1s. I am not sure how to get a reliable test into CI, I really do not want to delete the journal and developer or CI systems.
