Sebastiaan van Stijn 09053337c3 migrate to github.com/moby/sys/userns
Commit 2ce811e632 migrated the use of the
userns package to the github.com/moby/sys/user module.

After further discussion with maintainers, it was decided to move the
userns package to a separate module, as it has no direct relation with
"user" operations (other than having "user" in its name).

This patch migrates our code to use the new module.

Sebastiaan van Stijn bbbb44e189 migrate to github.com/moby/sys/user/userns
The userns package in libcontainer was integrated into the moby/sys/user
module at commit [3778ae603c706494fd1e2c2faf83b406e38d687d][1].

The userns package is used in many places, and currently either depends
on runc/libcontainer, or on containerd, both of which have a complex
dependency tree. This patch is part of a series of patches to unify the
implementations, and to migrate toward that implementation to simplify
the dependency tree.

Sebastiaan van Stijn c231772a5c update go:build tags to go1.23 to align with vendor.mod
Go maintainers started to unconditionally update the minimum go version
for golang.org/x/ dependencies to go1.23, which means that we'll no longer
be able to support any version below that when updating those dependencies;

> all: upgrade go directive to at least 1.23.0 [generated]
>
> By now Go 1.24.0 has been released, and Go 1.22 is no longer supported
> per the Go Release Policy (https://go.dev/doc/devel/release#policy).
>
> For golang/go#69095.

This updates our minimum version to go1.23, as we won't be able to maintain
compatibility with older versions because of the above.

Akihiro Suda 7ed7e6caf6 plugin: fix mounting /etc/hosts when running in UserNS
Fix `error mounting "/etc/hosts" to rootfs at "/etc/hosts": mount
/etc/hosts:/etc/hosts (via /proc/self/fd/6), flags: 0x5021: operation
not permitted`.

This error was introduced in 7d08d84b03
(`dockerd-rootless.sh: set rootlesskit --state-dir=DIR`) that changed
the filesystem of the state dir from /tmp to /run (in a typical setup).

Fix issue 47248

Brian Goff ec90839ca3 Don't sort plugin mounts slice
This was added as part of a53930a04f with
the intent to sort the mounts in the plugin config, but this was sorting
*all* the mounts from the default OCI spec which is problematic.

In reality we don't need to sort this because we are only adding a
self-binded mount to flag it as rshared.

We may want to look at sorting the plugin mounts before they are added
to the OCI spec in the future, but for now I think the existing behavior
is fine since the plugin author has control of the order (except for the
propagated mount).

Sebastiaan van Stijn 20028325da Merge pull request #35829 from cpuguy83/no_private_mount_for_plugins
Perform plugin mounts in the runtime
2018-02-21 12:28:13 +01:00
Brian Goff a53930a04f Plugins perform propagated mount in runtime spec
Setting up the mounts on the host increases chances of mount leakage and
makes for more cleanup after the plugin has stopped.
With this change all mounts for the plugin are performed by the
container runtime and automatically cleaned up when the container exits.

Brian Goff 426e610e43 Use runtime spec modifier for metrics plugin hook
Currently the metrics plugin uses a really hackish host mount with
propagated mounts to get the metrics socket into a plugin after the
plugin is alreay running.
This approach ends up leaking mounts which requires setting the plugin
manager root to private, which causes some other issues.

With this change, plugin subsystems can register a set of modifiers to
apply to the plugin's runtime spec before the plugin is ever started.
This will help to generalize some of the customization work that needs
to happen for various plugin subsystems (and future ones).

Specifically it lets the metrics plugin subsystem append a mount to the
runtime spec to mount the metrics socket in the plugin's mount namespace
rather than the host's and prevetns any leaking due to this mount.

Anusha Ragunathan 6d6185c257 Add support in plugin config for accessing host ipc namespace.
Plugins might need access to host ipc namespace. A good usecase is
a volume plugin running iscsi multipath commands that need access to
host kernel locks.
Tested with a custom plugin (aragunathan/global-net-plugin-full) that's
built with `"ipchost" : true` in config.json. Observed using
`readlink /proc/self/ns/ipc` that plugin and host have the same ns.

Tonis Tiigi 3d86b0c79b Implement content addressability for plugins
Move plugins to shared distribution stack with images.

Create immutable plugin config that matches schema2 requirements.

Ensure data being pushed is same as pulled/created.

Store distribution artifacts in a blobstore.

Run init layer setup for every plugin start.

Fix breakouts from unsafe file accesses.

Add support for `docker plugin install --alias`

Uses normalized references for default names to avoid collisions when using default hosts/tags.

Some refactoring of the plugin manager to support the change, like removing the singleton manager and adding manager config struct.
