* Support default profile for apparmorDaniel J Walsh2020-07-22
| | | | | | | | | | | | | | Currently you can not apply an ApparmorProfile if you specify --privileged. This patch will allow both to be specified simultaniosly. By default Apparmor should be disabled if the user specifies --privileged, but if the user specifies --security apparmor:PROFILE, with --privileged, we should do both.

| * allow switching of port-forward approaches in rootless/using slirp4netnsaleks-mariusz2020-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As of podman 1.8.0, because of commit da7595a, the default approach of providing port-forwarding in rootless mode has switched (and been hard-coded) to rootlessport, for the purpose of providing super performance. The side-effect of this switch is source within the container to the port-forwarded service always appears to originate from 127.0.0.1 (see issue #5138). This commit allows a user to specify if they want to revert to the previous approach of leveraging slirp4netns add_hostfwd() api which, although not as stellar performance, restores usefulness of seeing incoming traffic origin IP addresses. The change should be transparent; when not specified, rootlessport will continue to be used, however if specifying --net slirp4netns:slirplisten the old approach will be used. Note: the above may imply the restored port-forwarding via slirp4netns is not as performant as the new rootlessport approach, however the figures shared in the original commit that introduced rootlessport are as follows: slirp4netns: 8.3 Gbps, RootlessKit: 27.3 Gbps, which are more than sufficient for many use cases where the origin of traffic is more important than limits that cannot be reached due to bottlenecks elsewhere.

|/ | | | | | | | | | | | | | We were only using the Command field in specgen when determining whether to enable systemd if systemd=true (the default) was used. This does not include the entrypoint, and does not include any entrypoint/command sourced from the image - so an image could be running systemd and we'd not correctly detect this. Using the full, final command resolves this and matches Podman v1.9.x behavior. Fixes #6920 Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* | Fix container and pod create commands for remote createMatthew Heon2020-07-10
|/ | | | | | | | | | | | | | | | | | | | | | | In `podman inspect` output for containers and pods, we include the command that was used to create the container. This is also used by `podman generate systemd --new` to generate unit files. With remote podman, the generated create commands were incorrect since we sourced directly from os.Args on the server side, which was guaranteed to be `podman system service` (or some variant thereof). The solution is to pass the command along in the Specgen or PodSpecgen, where we can source it from the client's os.Args. This will still be VERY iffy for mixed local/remote use (doing a `podman --remote run ...` on a remote client then a `podman generate systemd --new` on the server on the same container will not work, because the `--remote` flag will slip in) but at the very least the output of `podman inspect` will be correct. We can look into properly handling `--remote` (parsing it out would be a little iffy) in a future PR. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* Implement --sdnotify cmdline option to control sd-notify behaviorJoseph Gooch2020-07-06
| | | | | | | | | | | | | | | | | | | --sdnotify container|conmon|ignore With "conmon", we send the MAINPID, and clear the NOTIFY_SOCKET so the OCI runtime doesn't pass it into the container. We also advertise "ready" when the OCI runtime finishes to advertise the service as ready. With "container", we send the MAINPID, and leave the NOTIFY_SOCKET so the OCI runtime passes it into the container for initialization, and let the container advertise further metadata. This is the default, which is closest to the behavior podman has done in the past. The "ignore" option removes NOTIFY_SOCKET from the environment, so neither podman nor any child processes will talk to systemd. This removes the need for hardcoded CID and PID files in the command line, and the PIDFile directive, as the pid is advertised directly through sd-notify.

* Allow empty host port in --publish flagMatthew Heon2020-06-29
| | | | | | | | | | | | | | | | | I didn't believe that this was actually legal, but it looks like it is. And, unlike our previous understanding (host port being empty means just use container port), empty host port actually carries the same meaning as `--expose` + `--publish-all` (that is, assign a random host port to the given container port). This requires a significant rework of our port handling code to handle this new case. I don't foresee this being commonly used, so I optimized having a fixed port number as fast path, which this random assignment code running after the main port handling code only if necessary.

* Set syslog for exit commands on log-level=debugMatthew Heon2020-06-24
| | | | | | | | | | | | | | | | We have a flag, --syslog, for telling logrus to log to syslog as well as to the terminal. Previously, this flag also set the exit command for containers to use `--syslog` (otherwise all output from exit commands is lost). I attempted to replicate this with Podman v2.0, but quickly ran into circular import hell (the flag is defined in cmd/podman, I needed it in cmd/podman/containers, cmd/podman imports cmd/podman/containers already, etc). Instead, let's just set the syslog flag automatically on `--log-level=debug` so we log exit commands automatically when debug-level logs are requested. This is consistent with Conmon and seems to make sense. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* Add support for the unless-stopped restart policyMatthew Heon2020-06-17
| | | | | | | | | | | | | | | | | | We initially believed that implementing this required support for restarting containers after reboot, but this is not the case. The unless-stopped restart policy acts identically to the always restart policy except in cases related to reboot (which we do not support yet), but it does not require that support for us to implement it. Changes themselves are quite simple, we need a new restart policy constant, we need to remove existing checks that block creation of containers when unless-stopped was used, and we need to update the manpages.

| * Re-add resource limit warnings to SpecgenMatthew Heon2020-06-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These were part of Podman v1.9, but were lost in the transition to using Specgen to create containers. Most resource limits are checked via the sysinfo package to ensure they are safe to use (the cgroup is mounted, kernel support is present, etc) and removed if not safe. Further, bounds checks are performed to ensure that values are valid. Ensure these warnings are printed client-side when they occur. This part is a little bit gross, as it happens in pkg/infra and not cmd/podman, which is largely down to how we implemented `podman run` - all the work is done in pkg/infra and it returns only once the container has exited, and we need warnings to print *before* the container runs. The solution here, while inelegant, avoid the need to extensively refactor our handling of run. Should fix blkio-limit warnings that were identified by the FCOS test suite.

| | | | | | | | | | | Add an `--infra-conmon-pidfile` flag to `podman-pod-create` to write the infra container's conmon process ID to a specified path. Several container sub-commands already support `--conmon-pidfile` which is especially helpful to allow for systemd to access and track the conmon processes.

| | | | | | | | | | | | | | Add a `CreateCommand` field to the pod config which includes the entire `os.Args` at pod-creation. Similar to the already existing field in a container config, we need this information to properly generate generic systemd unit files for pods. It's a prerequisite to support the `--new` flag for pods. Also add the `CreateCommand` to the pod-inspect data, which can come in handy for debugging, general inspection and certainly for the tests that are added along with the other changes.

| * Ensure that containers in pods properly set hostnameMatthew Heon2020-06-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we moved to the new Namespace types in Specgen, we made a distinction between taking a namespace from a pod, and taking it from another container. Due to this new distinction, some code that previously worked for both `--pod=$ID` and `--uts=container:$ID` has accidentally become conditional on only the latter case. This happened for Hostname - we weren't properly setting it in cases where the container joined a pod. Fortunately, this is an easy fix once we know to check the condition. Also, ensure that `podman pod inspect` actually prints hostname. Fixes #6494 Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* Enable detached exec for remoteMatthew Heon2020-06-02
| | | | | | | | | | | | | | | | | | | | | | | The biggest obstacle here was cleanup - we needed a way to remove detached exec sessions after they exited, but there's no way to tell if an exec session will be attached or detached when it's created, and that's when we must add the exit command that would do the removal. The solution was adding a delay to the exit command (5 minutes), which gives sufficient time for attached exec sessions to retrieve the exit code of the session after it exits, but still guarantees that they will be removed, even for detached sessions. This requires Conmon 2.0.17, which has the new `--exit-delay` flag. As part of the exit command rework, we can drop the hack we were using to clean up exec sessions (remove them as part of inspect). This is a lot cleaner, and I'm a lot happier about it. Otherwise, this is just plumbing - we need a bindings call for detached exec, and that needed to be added to the tunnel mode backend for entities. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* Enable cleanup processes for detached execMatthew Heon2020-05-20
| | | | | | | | | | | | | | | | | | | | | | The cleanup command creation logic is made public as part of this and wired such that we can call it both within SpecGen (to make container exit commands) and from the ABI detached exec handler. Exit commands are presently only used for detached exec, but theoretically could be turned on for all exec sessions if we wanted (I'm declining to do this because of potential overhead). I also forgot to copy the exit command from the exec config into the ExecOptions struct used by the OCI runtime, so it was not being added. There are also two significant bugfixes for exec in here. One is for updating the status of running exec sessions - this was always failing as I had coded it to remove the exit file *before* reading it, instead of after (oops). The second was that removing a running exec session would always fail because I inverted the check to see if it was running. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
