* rootless: automatically create a systemd scopeGiuseppe Scrivano2019-09-12
| | | | | | | | | | | | | | | | | | | | | when running in rootless mode and using systemd as cgroup manager create automatically a systemd scope when the user doesn't own the current cgroup. This solves a couple of issues: on cgroup v2 it is necessary that a process before it can moved to a different cgroup tree must be in a directory owned by the unprivileged user. This is not always true, e.g. when creating a session with su -l. Closes: https://github.com/containers/libpod/issues/3937 Also, for running systemd in a container it was before necessary to specify "systemd-run --scope --user podman ...", now this is done automatically as part of this PR.

* Volume lookup needs to include state to unmarshal intoMatthew Heon2019-09-11
| | | | | | | | | Lookup was written before volume states merged, but merged after, and CI didn't catch the obvious failure here. Without a valid state, we try to unmarshall into a null pointer, and 'volume rm' is completely broken because of it. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| * Do not prune images being used by a containerMatthew Heon2019-09-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Podman is not the only user of containers/storage, and as such we cannot rely on our database as the sole source of truth when pruning images. If images do not show as in use from Podman's perspective, but subsequently fail to remove because they are being used by a container, they're probably being used by Buildah or another c/storage client. Since the images in question are in use, we shouldn't error on failure to prune them - we weren't supposed to prune them in the first place.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change adds the following annotation to every container created by podman: ```json "Annotations": { "io.containers.manager": "libpod" } ``` Target of this annotaions is to indicate which project in the containers ecosystem is the major manager of a container when applications share the same storage paths. This way projects can decide if they want to manipulate the container or not. For example, since CRI-O and podman are not using the same container library (libpod), CRI-O can skip podman containers and provide the end user more useful information. A corresponding end-to-end test has been adapted as well. Relates to: https://github.com/cri-o/cri-o/pull/2761 Signed-off-by: Sascha Grunert <sgrunert@suse.com>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If c/storage paths are explicitly set to "" (the empty string) it will use compiled-in defaults. However, it won't tell us this via `storage.GetDefaultStoreOptions()` - we just get the empty string (which can put our defaults, some of which are relative to c/storage, in a bad spot). Hardcode a sane default for cases like this. Furthermore, add some sanity checks to paths, to ensure we don't use relative paths for core parts of libpod.

* | Add ability for volumes with options to mount/umountMatthew Heon2019-09-05
| | | | | | | | | | | | | | | | | | | | | | | | | | When volume options and the local volume driver are specified, the volume is intended to be mounted using the 'mount' command. Supported options will be used to volume the volume before the first container using it starts, and unmount the volume after the last container using it dies. This should work for any local filesystem, though at present I've only tested with tmpfs and btrfs. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* | Add volume stateMatthew Heon2019-09-05
| | | | | | | | | | | | | | | | | | | | | | | | We need to be able to track the number of times a volume has been mounted for tmpfs/nfs/etc volumes. As such, we need a mutable state for volumes. Add one, with the expected update/save methods in both states. There is backwards compat here, in that older volumes without a state will still be accepted.

* | Change volume driver and options JSON tagsMatthew Heon2019-09-05
|/ | | | | | | | | | | | | | | | In upcoming commits, we're going to turn on the backends for these fields. Volumes with these set will act fundamentally differently from other volumes. There will probably be validation required for each field. Until now, though, we've freely allowed creation of volumes with these set - they just did nothing. So we have no idea what could be in the DB with old volumes. Change the struct tags so we don't have to worry about old, unvalidated data. We'll start fresh with new volumes.

|\ | | | | Allow suid, exec, dev mount options to cancel nosuid/noexec/nodev
| * Set base mount options for bind mounts from base systemMatthew Heon2019-08-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If I mount, say, /usr/bin into my container - I expect to be able to run the executables in that mount. Unconditionally applying noexec would be a bad idea. Before my patches to change mount options and allow exec/dev/suid being set explicitly, we inferred the mount options from where on the base system the mount originated, and the options it had there. Implement the same functionality for the new option handling. There's a lot of performance left on the table here, but I don't know that this is ever going to take enough time to make it worth optimizing. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
| * Add support for 'exec', 'suid', 'dev' mount flagsMatthew Heon2019-08-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we explicitly set noexec/nosuid/nodev on every mount, with no ability to disable them. The 'mount' command on Linux will accept their inverses without complaint, though - 'noexec' is counteracted by 'exec', 'nosuid' by 'suid', etc. Add support for passing these options at the command line to disable our explicit forcing of security options. This also cleans up mount option handling significantly. We are still parsing options in more than one place, which isn't good, but option parsing for bind and tmpfs mounts has been unified.

[1]: https://github.com/containers/buildah/pull/1800 After applying the patch the same OCI image pull looks like this: ``` > ./bin/podman pull oci:alpine > podman images REPOSITORY TAG IMAGE ID CREATED SIZE localhost/alpine latest 4fa153a82426 5 weeks ago 5.85 MB ``` End-to-end tests have been adapted as well to cover the added scenario.
