* Add support for containers.conf volume timeoutsMatthew Heon2022-08-23
| | | | | | | | | | | | | | | | | | | | | | | | Also, do a general cleanup of all the timeout code. Changes include: - Convert from int to *uint where possible. Timeouts cannot be negative, hence the uint change; and a timeout of 0 is valid, so we need a new way to detect that the user set a timeout (hence, pointer). - Change name in the database to avoid conflicts between new data type and old one. This will cause timeouts set with 4.2.0 to be lost, but considering nobody is using the feature at present (and the lack of validation means we could have invalid, negative timeouts in the DB) this feels safe. - Ensure volume plugin timeouts can only be used with volumes created using a plugin. Timeouts on the local driver are nonsensical. - Remove the existing test, as it did not use a volume plugin. Write a new test that does. The actual plumbing of the containers.conf timeout in is one line in volume_api.go; the remainder are the above-described cleanups. Signed-off-by: Matthew Heon <mheon@redhat.com>
* Use SafeChown rather then chown for volumes on NFSDaniel J Walsh2022-07-12
| | | | | | | | | | | | | | | | NFS Servers will thrown ENOTSUPP error if you attempt to chown a directory to the same UID and GID as the directory already has. If volumes are stored on NFS directories this throws an ugly error and then works on the next try. Bottom line don't chown directories that already have the correct UID and GID.

* / add podman volume reload to sync volume pluginsPaul Holzinger2022-06-23
|/ | | | | | | | | | | | | | | | | | | Libpod requires that all volumes are stored in the libpod db. Because volume plugins can be created outside of podman, it will not show all available plugins. This podman volume reload command allows users to sync the libpod db with their external volume plugins. All new volumes from the plugin are also created in the libpod db and when a volume from the db no longer exists it will be removed if possible. There are some problems: - naming conflicts, in this case we only use the first volume we found. This is not deterministic. - race conditions, we have no control over the volume plugins. It is possible that the volumes changed while we run this command. Fixes #14207 Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* volume: add new option -o o=noquotaGiuseppe Scrivano2022-04-28
| | | | | | | | | | | | | | | | | add a new option to completely disable xfs quota usage for a volume. xfs quota set on a volume, even just for tracking disk usage, can cause weird errors if the volume is later re-used by a container with a different quota projid. More specifically, link(2) and rename(2) might fail with EXDEV if the source file has a projid that is different from the parent directory. To prevent such kind of issues, the volume should be created beforehand with `podman volume create -o o=noquota $ID` Closes: https://github.com/containers/podman/issues/14049 Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>

* Remove the runtime lockMatthew Heon2022-02-22
| | | | | | | | | | | | | | | | This primarily served to protect us against shutting down the Libpod runtime while operations (like creating a container) were happening. However, it was very inconsistently implemented (a lot of our longer-lived functions, like pulling images, just didn't implement it at all...) and I'm not sure how much we really care about this very-specific error case? Removing it also removes a lot of potential deadlocks, which is nice. [NO NEW TESTS NEEDED] Signed-off-by: Matthew Heon <mheon@redhat.com>

* Volumes: Only remove from DB if plugin removal succeedsMatthew Heon2021-08-18
| | | | | | | | | | | | | | | | | | Originally, Podman would unconditionally remove volumes from the DB, even if they failed to be removed from the volume plugin; this was a safety measure to ensure that `volume rm` can always remove a volume from the database, even if the plugin is misbehaving. However, this is a significant deivation from Docker, which refuses to remove if the plugin errors. These errors can be legitimate configuration issues which the user should address before the volume is removed, so Podman should also use this behaviour.

* Initial implementation of volume pluginsMatthew Heon2021-01-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This implements support for mounting and unmounting volumes backed by volume plugins. Support for actually retrieving plugins requires a pull request to land in containers.conf and then that to be vendored, and as such is not yet ready. Given this, this code is only compile tested. However, the code for everything past retrieving the plugin has been written - there is support for creating, removing, mounting, and unmounting volumes, which should allow full functionality once the c/common PR is merged. A major change is the signature of the MountPoint function for volumes, which now, by necessity, returns an error. Named volumes managed by a plugin do not have a mountpoint we control; instead, it is managed entirely by the plugin. As such, we need to cache the path in the DB, and calls to retrieve it now need to access the DB (and may fail as such). Notably absent is support for SELinux relabelling and chowning these volumes. Given that we don't manage the mountpoint for these volumes, I am extremely reluctant to try and modify it - we could easily break the plugin trying to chown or relabel it. Also, we had no less than *5* separate implementations of inspecting a volume floating around in pkg/infra/abi and pkg/api/handlers/libpod. And none of them used volume.Inspect(), the only correct way of inspecting volumes. Remove them all and consolidate to using the correct way. Compat API is likely still doing things the wrong way, but that is an issue for another day. Fixes #4304 Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* Add basic deadlock detection for container start/removeMatthew Heon2020-02-24
| | | | | | | | | | | | | | | We can easily tell if we're going to deadlock by comparing lock IDs before actually taking the lock. Add a few checks for this in common places where deadlocks might occur. This does not yet cover pod operations, where detection is more difficult (and costly) due to the number of locks being involved being higher than 2. Also, add some error wrapping on the Podman side, so we can tell people to use `system renumber` when it occurs. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Fix SELinux labels of volumesDaniel J Walsh2020-02-13
| | | | | | | | | | | | | | | If we attempt to label a volume and the file system does not support labeling, then just warn. SELinux may or may not work, on the volume. There is no way to setup a private label on a newly created volume without using the container mountlabel.

* Return a better error for volume name conflictsMatthew Heon2019-10-23
| | | | | | | | | | | | | | | | | When you try and create a new volume with the name of a volume that already exists, you presently get a thoroughly unhelpful error from `mkdir` as the volume attempts to create the directory it will be mounted at. An EEXIST out of mkdir is not particularly helpful to Podman users - it doesn't explain that the name is already taken by another volume. The solution here is potentially racy as the runtime is not locked, so someone else could take the name while we're still getting things set up, but that's a narrow timing window, and we will still return an error - just an error that's not as good as this one.

* Ensure volumes can be removed when they fail to unmountMatthew Heon2019-10-14
| | | | | | | | | | | | | | | | | | | | Also, ensure that we don't try to mount them without root - it appears that it can somehow not error and report that mount was successful when it clearly did not succeed, which can induce this case. We reuse the `--force` flag to indicate that a volume should be removed even after unmount errors. It seems fairly natural to expect that --force will remove a volume that is otherwise presenting problems. Finally, ignore EINVAL on unmount - if the mount point no longer exists our job is done.

* Correctly report errors on unmounting SHMMatthew Heon2019-09-05
| | | | | | | | | | | When we fail to remove a container's SHM, that's an error, and we need to report it as such. This may be part of our lingering storage woes. Also, remove MNT_DETACH. It may be another cause of the storage removal failures. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* 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.

| | | | | | | | | | | | | the compilation demands of having libpod in main is a burden for the remote client compilations. to combat this, we should move the use of libpod structs, vars, constants, and functions into the adapter code where it will only be compiled by the local client. this should result in cleaner code organization and smaller binaries. it should also help if we ever need to compile the remote client on non-Linux operating systems natively (not cross-compiled).

| | | | | | | | | | | | | | | | The Commit test is blatantly wrong and testing buggy behavior. We should be commiting the destination, if anything - and more likely nothing at all. When force-removing volumes, don't remove the volumes of containers we need to remove. This can lead to a chicken and the egg problem where the container removes the volume before we can. When we re-add volume locks this could lead to deadlocks. I don't really want to deal with this, and this doesn't seem a particularly harmful quirk, so we'll let this slide until we get a bug report.

* Remove locks from volumesMatthew Heon2019-02-21
| | | | | | | | | | | | | | | | | | | I was looking into why we have locks in volumes, and I'm fairly convinced they're unnecessary. We don't have a state whose accesses we need to guard with locks and syncs. The only real purpose for the lock was to prevent concurrent removal of the same volume. Looking at the code, concurrent removal ought to be fine with a bit of reordering - one or the other might fail, but we will successfully evict the volume from the state. Also, remove the 'prune' bool from RemoveVolume. None of our other API functions accept it, and it only served to toggle off more verbose error messages.
