| * Rewrite Rename backend in a more atomic fashionMatthew Heon2021-03-02
| | | | | | | | | | | | | | | | | | | | | | | | | | Move the core of renaming logic into the DB. This guarantees a lot more atomicity than we have right now (our current solution, removing the container from the DB and re-creating it, is *VERY* not atomic and prone to leaving a corrupted state behind if things go wrong. Moving things into the DB allows us to remove most, but not all, of this - there's still a potential scenario where the c/storage rename fails but the Podman rename succeeds, and we end up with a mismatched state.

* podman rmi: handle corrupted storage betterValentin Rothberg2021-03-01
| | | | | | | | | | | | | | | The storage can easily be corrupted when a build or pull process (or any process *writing* to the storage) has been killed. The corruption surfaces in Podman reporting that a given layer could not be found in the layer tree. Those errors must not be fatal but only logged, such that the image removal may continue. Otherwise, a user may be unable to remove an image. [NO TESTS NEEDED] as I do not yet have a reliable way to cause such a storage corruption.

| * container removal: handle already removed containersValentin Rothberg2021-02-23
| | | | | | | | | | | | | | | | | | | | | | | | Since commit d54478d8eaec, a container's lock is released before attempting to stop it via the OCI runtime. This opened the window for various kinds of race conditions. One of them led to #9479 where the removal+cleanup sequences of a `run --rm` session overlapped with `rm -af`. Make both execution paths more robust by handling the case of an already removed container. Fixes: #9479 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

* Fix podman network IDs handlingPaul Holzinger2021-02-22
| | | | | | | | | | | | | The libpod network logic knows about networks IDs but OCICNI does not. We cannot pass the network ID to OCICNI. Instead we need to make sure we only use network names internally. This is also important for libpod since we also only store the network names in the state. If we would add a ID there the same networks could accidentally be added twice. Fixes #9451 Signed-off-by: Paul Holzinger <paul.holzinger@web.de>

* Change source path resolution for volume copy-upMatthew Heon2021-02-17
| | | | | | | | | | | | | | | Instead of using the container's mountpoint as the base of the chroot and indexing from there by the volume directory, instead use the full path of what we want to copy as the base of the chroot and copy everything in it. This resolves the bug, ends up being a bit simpler code-wise (no string concatenation, as we already have the full path calculated for other checks), and seems more understandable than trying to resolve things on the destination side of the copy-up.

| * Fix an issue where copyup could fail with ENOENTMatthew Heon2021-02-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This one is rather bizarre because it triggers only on some systems. I've included a CI test, for example, but I'm 99% sure we use images in CI that have volumes over empty directories, and the earlier patch to change copy-up implementation passed CI without complaint. I can reproduce this on a stock F33 VM, but that's the only place I have been able to see it. Regardless, the issue: under certain as-yet-unidentified environmental conditions, the copier.Get method will return an ENOENT attempting to stream a directory that is empty. Work around this by avoiding the copy altogether in this case. Signed-off-by: Matthew Heon <mheon@redhat.com>
* | Do not reset storage when running inside of a containerDaniel J Walsh2021-02-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently if the host shares container storage with a container running podman, the podman inside of the container resets the storage on the host. This can cause issues on the host, as well as causes the podman command running the container, to fail to unmount /dev/shm. podman run -ti --rm --privileged -v /var/lib/containers:/var/lib/containers quay.io/podman/stable podman run alpine echo hello * unlinkat /var/lib/containers/storage/overlay-containers/a7f3c9deb0656f8de1d107e7ddff2d3c3c279c11c1635f233a0bffb16051fb2c/userdata/shm: device or resource busy * unlinkat /var/lib/containers/storage/overlay-containers/a7f3c9deb0656f8de1d107e7ddff2d3c3c279c11c1635f233a0bffb16051fb2c/userdata/shm: device or resource busy Since podman is volume mounting in the graphroot, it will add a flag to /run/.containerenv to tell podman inside of container whether to reset storage or not. Since the inner podman is running inside of the container, no reason to assume this is a fresh reboot, so if "container" environment variable is set then skip reset of storage. Also added tests to make sure /run/.containerenv is runnig correctly. Fixes: https://github.com/containers/podman/issues/9191 Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

| * make layer-tree lookup errors non-fatalValentin Rothberg2021-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Internally, Podman constructs a tree of layers in containers/storage to quickly compute relations among layers and hence images. To compute the tree, we intersect all local layers with all local images. So far, lookup errors have been fatal which has turned out to be a mistake since it seems fairly easy to cause storage corruptions, for instance, when killing builds. In that case, a (partial) image may list a layer which does not exist (anymore). Since the errors were fatal, there was no easy way to clean up and many commands were erroring out. To improve usability, turn the fatal errors into warnings that guide the user into resolving the issue. In this case, a `podman system reset` may be the approriate way for now.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old copy-up implementation was very unhappy with symlinks, which could cause containers to fail to start for unclear reasons when a directory we wanted to copy-up contained one. Rewrite to use the Buildah Copier, which is more recent and should be both safer and less likely to blow up over links. At the same time, fix a deadlock in copy-up for volumes requiring mounting - the Mountpoint() function tried to take the already-acquired volume lock.

| | | | | | | | | | | | | | | | | | | | | | When doing a container inspect on a container with unlimited ulimits, the value should be -1.
