| * 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. [NO TESTS NEEDED] because I have no reliable way to force it. [1] https://github.com/containers/podman/issues/8148#issuecomment-778253474 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

| * Rewrite copy-up to use buildah CopierMatthew Heon2021-02-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. But because the OCI spec requires the ulimit value to be uint64, we were displaying the inspect values as a uint64 as well. Simple change to display as an int64.

| | | | | | | | | | | | | | | | | | | | | | When resolving the workdir of a container, we may need to create unless the user set it explicitly on the command line. Otherwise, we just do a presence check. Unfortunately, there was a missing return that lead us to fall through into attempting to create and chown the workdir. That caused a regression when running on a read-only root fs. Fixes: #9230 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

| * workdir presence checksValentin Rothberg2021-01-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A container's workdir can be specified via the CLI via `--workdir` and via an image config with the CLI having precedence. Since images have a tendency to specify workdirs without necessarily shipping the paths with the root FS, make sure that Podman creates the workdir. When specified via the CLI, do not create the path, but check for its existence and return a human-friendly error. NOTE: `crun` is performing a similar check that would yield exit code 127. With this change, however, Podman performs the check and yields exit code 126. Since this is specific to `crun`, I do not consider it to be a breaking change of Podman.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | podman-remote search had some FIXMEs in tests that were failing. So I reworked the search handler to use the local abi. This means the podman search and podman-remote search will use the same functions. While doing this, I noticed we were just outputing errors via logrus.Error rather then returning them, which works ok for podman but the messages get lost on podman-remote. Changed the code to actually return the error messages to the caller. This allows us to turn on the remaining podman-remote FIXME tests. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
* | Ensure shutdown handler access is syncronizedMatthew Heon2021-01-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There was a potential race where two handlers could be added at the same time. Go Maps are not thread-safe, so that could do unpleasant things. Add a mutex to keep things safe. Also, swap the order or Register and Start for the handlers in Libpod runtime created. As written, there was a small gap between Start and Register where SIGTERM/SIGINT would be completely ignored, instead of stopping Podman. Swapping the two closes this gap.

* Move the cni lock file into the cni config dirPaul Holzinger2021-01-21
| | | | | | | | | | | | | | Commit(fe3faa517e1b) introduced a lock file for network create/rm calls. There is a problem with the location of the lock file. The lock file was stored in the tmpdir. Running multiple podman network create/remove commands in parallel with different tmpdirs made the lockfile inaccessible to the other process, and so parallel read/write operations to the cni config directory continued to occur. This scenario happened frequently during the e2e tests and caused some flakes. Fixes #9041 Signed-off-by: Paul Holzinger <paul.holzinger@web.de>
