* rootless: use RootlessKit port forwarderAkihiro Suda2020-01-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RootlessKit port forwarder has a lot of advantages over the slirp4netns port forwarder: * Very high throughput. Benchmark result on Travis: socat: 5.2 Gbps, slirp4netns: 8.3 Gbps, RootlessKit: 27.3 Gbps (https://travis-ci.org/rootless-containers/rootlesskit/builds/597056377) * Connections from the host are treated as 127.0.0.1 rather than 10.0.2.2 in the namespace. No UDP issue (#4586) * No tcp_rmem issue (#4537) * Probably works with IPv6. Even if not, it is trivial to support IPv6. (#4311) * Easily extensible for future support of SCTP * Easily extensible for future support of `lxc-user-nic` SUID network RootlessKit port forwarder has been already adopted as the default port forwarder by Rootless Docker/Moby, and no issue has been reported AFAIK. As the port forwarder is imported as a Go package, no `rootlesskit` binary is required for Podman.

* | Ensure SizeRw is shown when a user does 'inspect --size -t container'.Neville Cain2019-12-27
|/ | | | | | | | | | | | | | Currently, if a user requests the size on a container (inspect --size -t container), the SizeRw does not show up if the value is 0. It's because InspectContainerData is defined as int64 and there is an omit when empty. We do want to display it even if the value is empty. I have changed the type of SizeRw to be a pointer to an int64 instead of an int64. It will allow us todistinguish the empty value to the missing value. I updated the test "podman inspect container with size" to ensure we check thatSizeRw is displayed correctly. Closes #4744 Signed-off-by: NevilleC <neville.cain@qonto.eu>

This was rather odd, considering they were only in use by one container, and that container was in the process of being removed with the pod. After a bit of tracing, I realized that the cause is the ordering of container removal when we remove a pod. Normally, it's done in removeContainer() before volume removal (which is the last thing in that function). However, when we are removing a pod, we remove containers all at once, after removeContainer has already finished - meaning the container still exists when we try to remove its volumes, and thus the volume can't be removed. Solution: collect a list of all named volumes in use by the pod, and remove them all at once after every container in the pod is gone. This ensures that there are no dependency issues.

Expose this data as a `Config.CreateCommand` field in the container-inspect data as well. This information can be useful for debugging, as we can find out which command has created the container, and, if being created via the Podman CLI, we know exactly with which flags the container has been created with. The immediate motivation for this change is to use this information for `podman-generate-systemd` to generate systemd-service files that allow for creating new containers (in contrast to only starting existing ones).

Instead of getting the changes from the running container to the highest storage layer it got the changes from the highest layer to that parent's layer. For a one layer container this could mean that the complete root file-system is part of the checkpoint. With this commit this changes to use the same functionality as 'podman diff'. This actually enables to correctly diff the root file-system including tracking deleted files. This also removes the non-working helper functions from libpod/diff.go.

This is not a reliable method, though. The Podman frontend for exec could be killed before the session ended, or another Podman process could be holding the lock and prevent update (most notable in `run --rm`, when a container with an active exec session is stopped). To resolve this, add a function to reap active exec sessions from the state, and use it on cleanup (to clear sessions after the container stops) and remove (to do the same when --rm is passed). This is a bit more complicated than it ought to be because Kata and company exist, and we can't guarantee the exec session has a PID on the host, so we have to plumb this through to the OCI runtime.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the process, make everything in the config omitempty in TOML. We're seeing issues (notably [1]) where, after rewriting libpod.conf, fields that were not previously populated are written - and, because they were not previously written, they are included as empty. This is unfortunately different from not included at all - it means that we need to assume the user explicitly unset the value, and we can't use defaults. Setting omitempty prevents us from writing things that should not be written as they were not set originally.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It turns out we had two independent parsing impkementations for Dockerfile instructions out of --change. My previous commit fixed the one used in --change, but as I discovered to my dismay, commit used a different implementation. Remove that and use the new parsing implementation instead. While we're at it, fix some bugs in the current commit code. The addition of anonymous named volumes to Libpod recently means we can now include those in the image config when committing. Some changes (VOLUME, ENV, EXPOSE, LABEL) previously cleared the config of the former image when used; Docker does not do this, so I removed that behavior. Still needs fixing: the new implementation does not support ONBUILD, while the old one did. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* | Ensure volumes reacquire locks on state refreshMatthew Heon2019-12-02
|/ | | | | | | | | | | | | | | | | | | | | | | | After a restart, pods and containers both run a refresh() function to prepare to run after a reboot. Until now, volumes have not had a similar function, because they had no per-boot setup to perform. Unfortunately, this was not noticed when in-memory locking was introduced to volumes. The refresh() routine is, among other things, responsible for ensuring that locks are reserved after a reboot, ensuring they cannot be taken by a freshly-created container, pod, or volume. If this reservation is not done, we can end up with two objects using the same lock, potentially needing to lock each other for some operations - classic recipe for deadlocks. Add a refresh() function to volumes to perform lock reservation and ensure it is called as part of overall refresh(). Fixes #4605 Fixes #4621 Signed-off-by: Matthew Heon <matthew.heon@pm.me>

The most notable problems are storage issues, where the container cannot be removed from c/storage. When this occurs, we were faced with a choice. We can keep the container in the state, appearing in `podman ps` and available for other API operations, but likely unable to do any of them as it's been partially removed. Or we can remove it very early and clean up after it's already gone. We have, until now, used the second approach. The problem that arises is intermittent problems removing storage. We end up removing a container, failing to remove its storage, and ending up with a container permanently stuck in c/storage that we can't remove with the normal Podman CLI, can't use the name of, and generally can't interact with. A notable cause is when Podman is hit by a SIGKILL midway through removal, which can consistently cause `podman rm` to fail to remove storage. We now add a new state for containers that are in the process of being removed, ContainerStateRemoving. We set this at the beginning of the removal process. It notifies Podman that the container cannot be used anymore, but preserves it in the DB until it is fully removed. This will allow Remove to be run on these containers again, which should successfully remove storage if it fails. Fixes #3906 Signed-off-by: Matthew Heon <mheon@redhat.com>

This commit inhibits checkpointing containers started with '--rm' unless '--export' is used.
