| * Force Attach() to send a SIGWINCH and redrawMatthew Heon2020-09-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Basically, we want to force the application in the container to (iff the container was made with a terminal) redraw said terminal immediately after an attach completes, so the fresh Attach session will be able to see what's going on (e.g. will have a shell prompt). Our current attach functions are unfortunately geared more towards `podman run` than `podman attach` and will start forwarding resize events *immediately* instead of waiting until the attach session is alive (much safer for short-lived `podman run` sessions, but broken for the `podman attach` case). To avoid a major rewrite, let's just manually send a SIGWINCH after attach succeeds to force a redraw. Fixes #6253 Signed-off-by: Matthew Heon <matthew.heon@pm.me>

We did not, however, add entries to the group file, and this created problems - our passwd entries included the group the user is in, but said group might not exist. The solution is to mirror our logic for /etc/passwd modifications to also edit /etc/group in the container. Unfortunately, this is not a catch-all solution. Our logic here is only advanced enough to *add* to the group file - so if the group already exists but we add a user not a part of it, we will not modify that existing entry, and things remain inconsistent. We can look into adding this later if we absolutely need to, but it would involve adding significant complexity to this already massively complicated function. While we're here, address an edge case where Podman could add a user or group whose UID overlapped with an existing user or group. Also, let's make users able to log into users we added. Instead of generating user entries with an 'x' in the password field, indicating they have an entry in /etc/shadow, generate a '*' indicating the user has no password but can be logged into by other means e.g. ssh key, su.

* Ensure rootless containers without a passwd can startMatthew Heon2020-08-31
| | | | | | | | | | | | | | | | We want to modify /etc/passwd to add an entry for the user in question, but at the same time we don't want to require the container provide a /etc/passwd (a container with a single, statically linked binary and nothing else is perfectly fine and should be allowed, for example). We could create the passwd file if it does not exist, but if the container doesn't provide one, it's probably better not to make one at all. Gate changes to /etc/passwd behind a stat() of the file in the container returning cleanly. Fixes #7515 Signed-off-by: Matthew Heon <mheon@redhat.com>

| * Send HTTP Hijack headers after successful attachMatthew Heon2020-08-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our previous flow was to perform a hijack before passing a connection into Libpod, and then Libpod would attach to the container's attach socket and begin forwarding traffic. A problem emerges: we write the attach header as soon as the attach complete. As soon as we write the header, the client assumes that all is ready, and sends a Start request. This Start may be processed *before* we successfully finish attaching, causing us to lose output. The solution is to handle hijacking inside Libpod. Unfortunately, this requires a downright extensive refactor of the Attach and HTTP Exec StartAndAttach code. I think the result is an improvement in some places (a lot more errors will be handled with a proper HTTP error code, before the hijack occurs) but other parts, like the relocation of printing container logs, are just *bad*. Still, we need this fixed now to get CI back into good shape... Fixes #7195 Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When `podman rmi --force` is run, it will remove any containers that depend on the image. This includes Podman containers, but also any other c/storage users who may be using it. With Podman containers, we use the standard Podman removal function for containers, which handles all edge cases nicely, shutting down running containers, ensuring they're unmounted, etc. Unfortunately, no such convient function exists (or can exist) for all c/storage containers. Identifying the PID of a Buildah, CRI-O, or Podman container is extremely different, and those are just the implementations under the containers org. We can't reasonably be able to know if a c/storage container is *in use* and safe for removal if it's not a Podman container. At the very least, though, we can attempt to unmount a storage container before removing it. If it is in use, this will fail (probably with a not-particularly-helpful error message), but if it is not in use but not fully cleaned up, this should make our removing it much more robust than it normally is.

| * Ensure pod infra containers have an exit commandMatthew Heon2020-08-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most Libpod containers are made via `pkg/specgen/generate` which includes code to generate an appropriate exit command which will handle unmounting the container's storage, cleaning up the container's network, etc. There is one notable exception: pod infra containers, which are made entirely within Libpod and do not touch pkg/specgen. As such, no cleanup process, network never cleaned up, bad things can happen. There is good news, though - it's not that difficult to add this, and it's done in this PR. Generally speaking, we don't allow passing options directly to the infra container at create time, but we do (optionally) proxy a pre-approved set of options into it when we create it. Add ExitCommand to these options, and set it at time of pod creation using the same code we use to generate exit commands for normal containers.

|/ | | | | | | | | | | | | | | | On cgroups v1 systems, we need to mount /sys/fs/cgroup/systemd into the container. We were doing this with no explicit mount propagation tag, which means that, under some circumstances, the shared mount propagation could be chosen - which, combined with the fact that we need a mount to mask /sys/fs/cgroup/systemd/release_agent in the container, means we would leak a never-ending set of mounts under /sys/fs/cgroup/systemd/ on container restart. Fortunately, the fix is very simple - hardcode mount propagation to something that won't leak. Signed-off-by: Matthew Heon <mheon@redhat.com>
* Unconditionally retrieve pod names via APIMatthew Heon2020-08-10
| | | | | | | | | | | | | | | | | | The ListContainers API previously had a Pod parameter, which determined if pod name was returned (but, notably, not Pod ID, which was returned unconditionally). This was fairly confusing, so we decided to deprecate/remove the parameter and return it unconditionally. To do this without serious performance implications, we need to avoid expensive JSON decodes of pod configuration in the DB. The way our Bolt tables are structured, retrieving name given ID is actually quite cheap, but we did not expose this via the Libpod API. Add a new GetName API to do this.
