| * logs: k8s-file: fix raceValentin Rothberg2021-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix a race in the k8s-file logs driver. When "following" the logs, Podman will print the container's logs until the end. Previously, Podman logged until the state transitioned into something non-running which opened up a race with the container still running, possibly in the "stopping" state. To fix the race, log until we've seen the wait event for the specific container. In that case, conmon will have finished writing all logs to the file, and Podman will read it until EOF. Further tweak the integration tests for testing `logs -f` on a running container. Previously, the test only checked for one of two lines stating that there was a race. Indeed the race was in using `run --rm` where a log file may be removed before we could fully read it. Fixes: #10596 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* | Improve systemd-resolved detectionPaul Holzinger2021-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | When 127.0.0.53 is the only nameserver in /etc/resolv.conf assume systemd-resolved is used. This is better because /etc/resolv.conf does not have to be symlinked to /run/systemd/resolve/stub-resolv.conf in order to use systemd-resolved.

* | Add parameter to specify checkpoint archive compressionAdrian Reber2021-06-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The checkpoint archive compression was hardcoded to `archive.Gzip`. There have been requests to make the used compression algorithm selectable. There was especially the request to not compress the checkpoint archive to be able to create faster checkpoints when not compressing it. This also changes the default from `gzip` to `zstd`. This change should not break anything as the restore code path automatically handles whatever compression the user provides during restore. Signed-off-by: Adrian Reber <areber@redhat.com>
* | add ipv6 nameservers only when the container has ipv6 enabledPaul Holzinger2021-06-03
|/ | | | | | | | | | | | | | | The containers /etc/resolv.conf allways preserved the ipv6 nameserves from the host even when the container did not supported ipv6. Check if the cni result contains an ipv6 address or slirp4netns has ipv6 support enabled and only add the ipv6 nameservers when this is the case. The test needs to have an ipv6 nameserver in the hosts /etc/hosts but we should never mess with this file on the host. Therefore the test is skipped when no ipv6 is detected.

| * Ensure that container still exists when removingMatthew Heon2021-05-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After #8906, there is a potential race condition in container removal of running containers with `--rm`. Running containers must first be stopped, which was changed to unlock the container to allow commands like `podman ps` to continue to run while stopping; however, this also means that the cleanup process can potentially run before we re-lock, and remove the container from under us, resulting in error messages from `podman rm`. The end result is unchanged, the container is still cleanly removed, but the `podman rm` command will seem to have failed. Work around this by pinging the database after we stop the container to make sure it still exists. If it doesn't, our job is done and we can exit cleanly.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the containers.conf field "NetNS" is set to "Bridge" and the "RootlessNetworking" field is set to "cni", Podman will now handle rootless in the same way it does root - all containers will be joined to a default CNI network, instead of exclusively using slirp4netns. If no CNI default network config is present for the user, one will be auto-generated (this also works for root, but it won't be nearly as common there since the package should already ship a config). I eventually hope to remove the "NetNS=Bridge" bit from containers.conf, but let's get something in for Brent to work with. Signed-off-by: Matthew Heon <mheon@redhat.com>

|\ \ | |/ |/| journald logger: fix race condition
| * journald logger: fix race conditionValentin Rothberg2021-05-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix a race in journald driver. Following the logs implies streaming until the container is dead. Streaming happened in one goroutine, waiting for the container to exit/die and signaling that event happened in another goroutine. The nature of having two goroutines running simultaneously is pretty much the core of the race condition. When the streaming goroutines received the signal that the container has exitted, the routine may not have read and written all of the container's logs. Fix this race by reading both, the logs and the events, of the container and stop streaming when the died/exited event has been read. The died event is guaranteed to be after all logs in the journal which guarantees not only consistencty but also a deterministic behavior. Note that the journald log driver now requires the journald event backend to be set. Fixes: #10323 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

|/ | | | | | | | | | | | | | When attempting to copy files into and out of running containers within the host pidnamespace, the code was attempting to join the host pidns again, and getting an error. This was causing the podman cp command to fail. Since we are already in the host pid namespace, we should not be attempting to join.

| * Ensure that :Z/:z/:U can be used with named volumesMatthew Heon2021-05-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Docker allows relabeling of any volume passed in via -v, even including named volumes. This normally isn't an issue at all, given named volumes get the right label for container access automatically, but this becomes an issue when volume plugins are involved - these aren't managed by Podman, and may well be unaware of SELinux labelling. We could automatically relabel these volumes on creation, but I'm still reluctant to do that (feels like it could break things). Instead, let's allow :z and :Z to be used with named volumes, so users can explicitly request relabel of a volume plugin-backed volume. We also get :U at the same time. I don't see any real need for it but it also doesn't seem to hurt, so I didn't bother disabling it. Fixes #10273 Signed-off-by: Matthew Heon <mheon@redhat.com>

Further changes: * Fix a bug in the journald logging which requires to strip trailing new lines from the message. The system tests did not pass due to empty new lines. Triggered by changing the default logger to journald in containers/common. * Fix another bug in the journald logging which embedded the container ID inside the message rather than the specifid field. That surfaced in a preceeding whitespace of each log line which broke the system tests. * Alter the system tests to make sure that the k8s-file and the journald logging drivers are executed. * A number of e2e tests have been changed to force the k8s-file driver to make them pass when running inside a root container. * Increase the timeout in a kill test which seems to take longer now.
