* Ensure that exec sends resize eventsMatthew Heon2020-03-25
| | | | | | | | | | | | | | | We previously tried to send resize events only after the exec session successfully started, which makes sense (we might drop an event or two that came in before the exec session started otherwise). However, the start function blocks, so waiting actually means we send no resize events at all, which is obviously worse than losing a few.. Sending resizes before attach starts seems to work fine in my testing, so let's do that until we get bug reports that it doesn't work. Fixes #5584 Signed-off-by: Matthew Heon <mheon@redhat.com>

| * Attempt manual removal of CNI IP allocations on refreshMatthew Heon2020-03-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We previously attempted to work within CNI to do this, without success. So let's do it manually, instead. We know where the files should live, so we can remove them ourselves instead. This solves issues around sudden reboots where containers do not have time to fully tear themselves down, and leave IP address allocations which, for various reasons, are not stored in tmpfs and persist through reboot.

| * Add structure for new exec session tracking to DBMatthew Heon2020-03-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As part of the rework of exec sessions, we need to address them independently of containers. In the new API, we need to be able to fetch them by their ID, regardless of what container they are associated with. Unfortunately, our existing exec sessions are tied to individual containers; there's no way to tell what container a session belongs to and retrieve it without getting every exec session for every container. This adds a pointer to the container an exec session is associated with to the database. The sessions themselves are still stored in the container. Exec-related APIs have been restructured to work with the new database representation. The originally monolithic API has been split into a number of smaller calls to allow more fine-grained control of lifecycle. Support for legacy exec sessions has been retained, but in a deprecated fashion; we should remove this in a few releases. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| | | | | | | | | | | | | | | | | | As part of the rework of exec sessions, we want to split Create and Start - and, as a result, we need to keep everything needed to start exec sessions in the struct, not just the bare minimum for tracking running ones.

If the label is present and set to "image", Podman reaches out to the corresponding registry to check if the image has been updated. We consider an image to be updated if the digest in the local storage is different than the one of the remote image. If an image must be updated, Podman pulls it down and restarts the container. Note that the restarting sequence relies on systemd. At container-creation time, Podman looks up the "PODMAN_SYSTEMD_UNIT" environment variables and stores it verbatim in the container's label. This variable is now set by all systemd units generated by `podman-generate-systemd` and is set to `%n` (i.e., the name of systemd unit starting the container). This data is then being used in the auto-update sequence to instruct systemd (via DBUS) to restart the unit and hence to restart the container. Note that this implementation of auto-updates relies on systemd and requires a fully-qualified image reference to be used to create the container. This enforcement is necessary to know which image to actually check and pull. If we used an image ID, we would not know which image to check/pull anymore.

If the user or image specified capabilities that are not in the default set, the container will print an error message and will continue to run with the default capabilities.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Until now, we've been validating every part of container configuration through the With... functions that set the options. This if fine when we are just validating the options to an individual function, but things get complicated once we need to validate conflicts between different options. We don't know the order in which things were passed, so we need the validation on both of the potential options that can conflict, resulting in significant code duplication. To solve this, add a validate() function for containers, and use this to check whether everything is in a good state. We can probably move more into this function (there are other parts of container creation that also do validation of a sort) but this is a good start to simplifying our options.
