* Return empty runtime directory if we're not rootlessJonathan Dieter2019-12-07
| | | | | | | | | | | | | | | | | | | Currently, we return a runtime directory of the form `/run/user/<uid>`, even when running as root. Depending on configuration, that directory may be deleted when the user logs out, which is quite awkward when the container is started as a systemd service and then someone logs in and out as root. This patch fixes the problem by returning an empty runtime directory if the container is being started by root. The runtime should automatically use the default runtime directory (`/run/crun` when crun is used), which should be accessible to root. Tested in Fedora 31 by running containers under both root and a regular user. State for root containers is stored in `/run/crun`, while state for rootless containers is in `/run/user/<uid>/crun`.

* Add ONBUILD support to --changeMatthew Heon2019-12-05
| | | | | | | | | | | Return types had to change a bit for this, but since we can wrap the old v1.ImageConfig, changes are overall not particularly bad. At present, I believe this only works with commit, not import. This matches how things were before we changed to the new parsing so I think this is fine.

* Completely rework --change parsingMatthew Heon2019-12-04
| | | | | | | | | | | | The way we were trying to parse was very broken. I originally attempted to use Buildah's Dockerfile parser here, but dealing with it (and convincing it to accept only a limited subset, and only one instruction at a time) was challenging, so I rewrote a subset of Dockerfile parsing. This should handle most common cases well, though there are definitely unhandled edge cases for ENV and LABEL. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

I can't figure out the reason for go.mod tracking github.com/containers/image v3.0.2+incompatible // indirect ((go mod graph) lists it as a direct dependency of libpod, but (go list -json -m all) lists it as an indirect dependency), but at least looking at the vendor subdirectory, it doesn't seem to be actually used in the built binaries.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If I mount, say, /usr/bin into my container - I expect to be able to run the executables in that mount. Unconditionally applying noexec would be a bad idea. Before my patches to change mount options and allow exec/dev/suid being set explicitly, we inferred the mount options from where on the base system the mount originated, and the options it had there. Implement the same functionality for the new option handling. There's a lot of performance left on the table here, but I don't know that this is ever going to take enough time to make it worth optimizing. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
| * Add support for 'exec', 'suid', 'dev' mount flagsMatthew Heon2019-08-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we explicitly set noexec/nosuid/nodev on every mount, with no ability to disable them. The 'mount' command on Linux will accept their inverses without complaint, though - 'noexec' is counteracted by 'exec', 'nosuid' by 'suid', etc. Add support for passing these options at the command line to disable our explicit forcing of security options. This also cleans up mount option handling significantly. We are still parsing options in more than one place, which isn't good, but option parsing for bind and tmpfs mounts has been unified.

* Move the HostConfig portion of Inspect inside libpodMatthew Heon2019-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we first began writing Podman, we ran into a major issue when implementing Inspect. Libpod deliberately does not tie its internal data structures to Docker, and stores most information about containers encoded within the OCI spec. However, Podman must present a CLI compatible with Docker, which means it must expose all the information in 'docker inspect' - most of which is not contained in the OCI spec or libpod's Config struct. Our solution at the time was the create artifact. We JSON'd the complete CreateConfig (a parsed form of the CLI arguments to 'podman run') and stored it with the container, restoring it when we needed to run commands that required the extra info. Over the past month, I've been looking more at Inspect, and refactored large portions of it into Libpod - generating them from what we know about the OCI config and libpod's (now much expanded, versus previously) container configuration. This path comes close to completing the process, moving the last part of inspect into libpod and removing the need for the create artifact. This improves libpod's compatability with non-Podman containers. We no longer require an arbitrarily-formatted JSON blob to be present to run inspect.

| | | | | | | | | | | | | | | | | use a pause process to keep the user and mount namespace alive. The pause process is created immediately on reload, and all successive Podman processes will refer to it for joining the user&mount namespace. This solves all the race conditions we had on joining the correct namespaces using the conmon processes. As a fallback if the join fails for any reason (e.g. the pause process was killed), then we try to join the running containers as we were doing before.
