* Revert "Podman Pod Create --cpus and --cpuset-cpus flags"Matthew Heon2021-08-11
| | | | | | | | | This reverts commit bbd085ad1e3cf9c5b543c907ad7014ccf8a5cb34. The cgroup work to enable these has not happened yet and will not be ready in time for the release of Podman 3.3.0. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| | | | | | | | | The slirp4netns path can be set in the config file or with --network-cmd-path. Podman info should read the version information correctly and not use PATH in this case. Also show the slirp4netns version information to root users. Signed-off-by: Paul Holzinger <pholzing@redhat.com>

* Do not add an entry to /etc/hosts with `--net=host`Matthew Heon2021-08-10
| | | | | | | | | | | | | | | To match Docker's behavior, in the `--net=host` case, we need to use the host's `/etc/hosts` file, unmodified (without adding an entry for the container). We will still respect hosts from `--add-host` but will not make any automatic changes. Fortuntely, this is strictly a matter of removal and refactoring as we already base our `/etc/hosts` on the host's version - just need to remove the code that added entries when net=host was set.

* podman info: try qfile before equeryEd Santiago2021-08-10
| | | | | | | | | | | | | | | | | | podman info takes >20s on Gentoo, because equery is s..l..o..w. qfile is much faster and, I suspect, present in most Gentoo installations, so let's try it first. And, because packageVersion() was scarily unmaintainable, refactor it. Define a simple (string) list of packaging tools to query (rpm, dpkg, ...) and iterate until we find one that works. IMPORTANT NOTE: the Debian (and, presumably, Ubuntu) query does not include version number! There is no standard way on Debian to get a package version from a file path, you can only do it via pipes of chained commands, and I have no desire to implement that.

* fix rootless port forwarding with network dis-/connectPaul Holzinger2021-08-06
| | | | | | | | | | | | | | | | | | | | | | | | The rootlessport forwarder requires a child IP to be set. This must be a valid ip in the container network namespace. The problem is that after a network disconnect and connect the eth0 ip changed. Therefore the packages are dropped since the source ip does no longer exists in the netns. One solution is to set the child IP to 127.0.0.1, however this is a security problem. [1] To fix this we have to recreate the ports after network connect and disconnect. To make this work the rootlessport process exposes a socket where podman network connect/disconnect connect to and send to new child IP to rootlessport. The rootlessport process will remove all ports and recreate them with the new correct child IP. Also bump rootlesskit to v0.14.3 to fix a race with RemovePort().

|\ | | | | | | | | adrianreber/2021-07-12-checkpoint-restore-into-pod Add support for checkpoint/restore into and out of pods
| * Support checkpoint/restore with podsAdrian Reber2021-07-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support to checkpoint containers out of pods and restore container into pods. It is only possible to restore a container into a pod if it has been checkpointed out of pod. It is also not possible to restore a non pod container into a pod. The main reason this does not work is the PID namespace. If a non pod container is being restored in a pod with a shared PID namespace, at least one process in the restored container uses PID 1 which is already in use by the infrastructure container. If someone tries to restore container from a pod with a shared PID namespace without a shared PID namespace it will also fail because the resulting PID namespace will not have a PID 1.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There was an race condition when calling `GetRootlessCNINetNs()`. It created the rootless cni directory before it got locked. Therefore another process could have called cleanup and removed this directory before it was used resulting in errors. The lockfile got moved into the XDG_RUNTIME_DIR directory to prevent a panic when the parent dir was removed by cleanup. Fixes #10930 Fixes #10922 To make this even more robust `GetRootlessCNINetNs()` will now return locked. This guarantees that we can run `Do()` after `GetRootlessCNINetNs()` before another process could have called `Cleanup()` in between. [NO TESTS NEEDED] CI is flaking, hopefully this will fix it.

|/ | | | | | | | | | | | | | | | | | | The rootless cni namespace needs a valid /etc/resolv.conf file. On some distros is a symlink to somewhere under /run. Because the kernel will follow the symlink before mounting, it is not possible to mount a file at exactly /etc/resolv.conf. We have to ensure that the link target will be available in the rootless cni mount ns. Fixes #10855 Also fixed a bug in the /var/lib/cni directory lookup logic.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | First, make podman diff accept optionally a second argument. This allows the user to specify a second image/container to compare the first with. If it is not set the parent layer will be used as before. Second, podman container diff should only use containers and podman image diff should only use images. Previously, podman container diff would use the image when both an image and container with this name exists. To make this work two new parameters have been added to the api. If they are not used the previous behaviour is used. The same applies to the bindings. Fixes #10649 Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* | podman service reaperPaul Holzinger2021-07-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new service reaper package. Podman currently does not reap all child processes. The slirp4netns and rootlesskit processes are not reaped. The is not a problem for local podman since the podman process dies before the other processes and then init will reap them for us. However with podman system service it is possible that the podman process is still alive after slirp died. In this case podman has to reap it or the slirp process will be a zombie until the service is stopped. The service reaper will listen in an extra goroutine on SIGCHLD. Once it receives this signal it will try to reap all pids that were added with `AddPID()`. While I would like to just reap all children this is not possible because many parts of the code use `os/exec` with `cmd.Wait()`. If we reap before `cmd.Wait()` things can break, so reaping everything is not an option. [NO TESTS NEEDED] Fixes #9777 Signed-off-by: Paul Holzinger <pholzing@redhat.com>
