| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This bug was introduced in https://github.com/containers/podman/pull/8906. When we use 'podman rm/restart/stop/kill etc...' command to the container running with --rm, the OCI runtime directory remains at /run/<runtime name> (root user) or /run/user/<user id>/<runtime name> (rootless user). This bug could cause other bugs. For example, when we checkpoint the container running with --rm (podman checkpoint --export) and restore it (podman restore --import) with crun, error message "Error: OCI runtime error: crun: container `<container id>` already exists" is outputted. This error is caused by an attempt to restore the container with the same container ID as the remaining OCI runtime's container ID. Therefore, I fix that the cleanupRuntime() function runs to remove the OCI runtime directory, even if the container has already been removed by --rm option.

Because volume plugins can be created outside of podman, it will not show all available plugins. This podman volume reload command allows users to sync the libpod db with their external volume plugins. All new volumes from the plugin are also created in the libpod db and when a volume from the db no longer exists it will be removed if possible. There are some problems: - naming conflicts, in this case we only use the first volume we found. This is not deterministic. - race conditions, we have no control over the volume plugins. It is possible that the volumes changed while we run this command. Fixes #14207 Signed-off-by: Paul Holzinger <pholzing@redhat.com>

| | |/ / | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | currently, setting any sort of resource limit in a pod does nothing. With the newly refactored creation process in c/common, podman ca now set resources at a pod level meaning that resource related flags can now be exposed to podman pod create. cgroupfs and systemd are both supported with varying completion. cgroupfs is a much simpler process and one that is virtually complete for all resource types, the flags now just need to be added. systemd on the other hand has to be handeled via the dbus api meaning that the limits need to be passed as recognized properties to systemd. The properties added so far are the ones that podman pod create supports as well as `cpuset-mems` as this will be the next flag I work on. Signed-off-by: Charlie Doern <cdoern@redhat.com>

We are guaranteed that all containers are gone after a refresh, we should not worry about exit codes given this. Secondly: alter the way pruning was done. We were updating the DB by calling Update from within an existing View, and stacking an RW transaction on top of an existing RO one seems dodgy; further, modifying a bucket while iterating over it with ForEach is undefined behavior. Hopefully this will resolve our CI issues. Signed-off-by: Matthew Heon <mheon@redhat.com>

The three bug fixes are not split into separate commits as tests won't pass otherwise; avoidable noise when bisecting future issues. 1) Podman conflated states: even when asking to wait for the `exited` state, Podman returned as soon as a container transitioned to `stopped`. The issues surfaced in Gitlab tests to fail [1] as `conmon`'s buffers have not (yet) been emptied when attaching to a container right after a wait. The race window was extremely narrow, and I only managed to reproduce with the Gitlab runner [1] unit tests. 2) The clearer separation between `exited` and `stopped` revealed a race condition predating the changes. If a container is configured for autoremoval (e.g., via `run --rm`), the "run" process competes with the "cleanup" process running in the background. The window of the race condition was sufficiently large that the "cleanup" process has already removed the container and storage before the "run" process could read the exit code and hence waited indefinitely. Address the exit-code race condition by recording exit codes in the main libpod database. Exit codes can now be read from a database. When waiting for a container to exit, Podman first waits for the container to transition to `exited` and will then query the database for its exit code. Outdated exit codes are pruned during cleanup (i.e., non-performance critical) and when refreshing the database after a reboot. An exit code is considered outdated when it is older than 5 minutes. While the race condition predates this change, the waiting process has apparently always been fast enough in catching the exit code due to issue 1): `exited` and `stopped` were conflated. The waiting process hence caught the exit code after the container transitioned to `stopped` but before it `exited` and got removed. 3) With 1) and 2), Podman is now waiting for a container to properly transition to the `exited` state. Some tests did not pass after 1) and 2) which revealed the third bug: `conmon` was executed with its working directory pointing to the OCI runtime bundle of the container. The changed working directory broke resolving relative paths in the "cleanup" process. The "cleanup" process error'ed before actually cleaning up the container and waiting "main" process ran indefinitely - or until hitting a timeout. Fix the issue by executing `conmon` with the same working directory as Podman. Note that fixing 3) *may* address a number of issues we have seen in the past where for *some* reason cleanup processes did not fire.

This is helpful to integrate podman in systemd so that the spawned conmon lives in the same cgroup as the service that created it. Unfortunately this breaks when podman daemon is running in a systemd service since the same check is in place thus all the conmon processes end up in the same cgroup as the podman daemon. When the podman daemon systemd service stops the conmon processes are also terminated as well as the containers they monitor. Improve the check to exclude podman running as a daemon.

Fix the code to check Stopped as well (we omit Exited entirely but it's a cheap check and our state logic could change in the future). Also, return an error, instead of exiting cleanly - the Kill failed, after all. ErrCtrStateInvalid is already handled by the sig-proxy logic so there won't be issues.
