* Store cgroup manager on a per-container basisMatthew Heon2020-10-08
| | | | | | | | | | | | | | | | | | | | | When we create a container, we assign a cgroup parent based on the current cgroup manager in use. This parent is only usable with the cgroup manager the container is created with, so if the default cgroup manager is later changed or overridden, the container will not be able to start. To solve this, store the cgroup manager that created the container in container configuration, so we can guarantee a container with a systemd cgroup parent will always be started with systemd cgroups. Unfortunately, this is very difficult to test in CI, due to the fact that we hard-code cgroup manager on all invocations of Podman in CI. Fixes #7830 Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make Podman pod operations that do not involve starting containers (which needs to be done in a specific order) use the same parallel operation code we use to make `podman stop` on large numbers of containers fast. We were previously stopping containers in a pod serially, which could take up to the timeout (default 15 seconds) for each container - stopping 100 containers that do not respond to SIGTERM would take 25 minutes. To do this, refactor the parallel operation code a bit to remove its dependency on libpod (damn circular import restrictions...) and use parallel functions that just re-use the standard container API operations - maximizes code reuse (previously each pod handler had a separate implementation of the container function it performed). This is a bit of a palate cleanser after fighting CI for two days - nice to be able to return to a land of sanity. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| |/ | | | | | | | | | | | | | | | | | | due to a lack of "locking" on cni operations, we could get ourselves in trouble when doing rapid creation or removal of networks. added a simple file lock to deal with the collision and because it is not considered a performent path, use of the file lock should be ok. if proven otherwise in the future, some generic shared memory lock should be implemented for libpod and also used here. moved pkog/network to libpod/network because libpod is now being pulled into the package and it has therefore lost its generic nature. this will make it easier to absorb into libpod as we try to make the network closer to core operations.

This is not the behavior that is encountered, as this test shows: it is instead considered an error if and only if the Relabeling operation returns ENOTSUP, spitting out a somewhat incongruous error message, while all other error types that may be returned are logged without being propogated, with an even more incongruous error message saying that the operation was not supported. The comparison was changed to match the behavior documented by the log messages, and a test was added that will simulate executing this function on a path where the mounted filesystem does not support SELinux labels, with the assertion that the function should not return an error in order to highlight the condition these changes seek to alleviate.

Also fixed an issue when images were matching other images names based on prefix, causing images to always be pulled. I had named an image myfedora and when ever I pulled fedora, the system thought that it there were two images named fedora since it was checking for the name fedora as well as the prefix fedora. I changed it to check for fedora and the prefix /fedora, to prefent failures like I had. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
* | | HTTP Attach: Wait until both STDIN and STDOUT finishMatthew Heon2020-09-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the old code, there was a chance that we could return when only one of STDIN or STDOUT had finished - this could lead to us dropping either input to the container, or output from it, in the case that one stream terminated early. To resolve this, use separate channels to return STDOUT and STDIN errors, and track which ones have returned cleanly to ensure that we need bith in order to return from the HTTP attach function and pass control back to the HTTP handler (which would assume we exited cleanly and close the client's attach connection).

This guarantee was broken for containers where the `--user` flag was specified; this patch resolves that. Somewhere in the Exec rewrite for APIv2, I changed the location where the container's User is passed into the exec session (similar to groups, we also want to preserve user unless overridden). The lower-level Exec APIs already handled setting user and group appropriately if not specified when the exec session was created, but I added duplicate code to handle this higher in the stack - and that code only handled setting user, not supplemental groups, breaking support in that specific case. Two things conspired to make this one hard to track down: first, things were only broken if the container explicitly set a user; otherwise, the container user would still appear to be unset to the lower-level code, which would properly set supplemental groups (this tricked our existing test into passing). Also, the `crun` OCI runtime will add the groups without prompting, which further masked the problem there. I debated making `runc` do the same, but in the end it's better to fix this in Podman - it's better to be explicit about what we want done so we will work with all OCI runtimes.
