fixes #5317

- What I did

We had a report in fixes #5317 of a panic at

pl.mu.Lock()

Looks like this will happen if the call to create a PluginServer fails and returns nil, since we're not checking for nilness before attempting to call Close:

cli/cmd/docker/docker.go

Lines 247 to 251 in 87c6624

defer func() {
// Close the server when plugin execution is over, so that in case
// it's still open, any sockets on the filesystem are cleaned up.
_ = srv.Close()
}()

_ = srv.Close()

- How I did it

Added a nil check to PluginServer.Close(). We could also have addressed this at the caller sites, but this seems more robust for little cost.

- How to verify it

- Description for the changelog

Fixed issue where main CLI process would sometimes panic while running a plugin.

Wondering if we should also backport this to 26.1.

@vvoland vvoland added this to the 28.0.0 milestone Aug 7, 2024

It's probably ok to cherry-pick; we may not be doing releases from that branch, but a cherry-pick doesn't do harm
