vm: Limit size of descriptions #1891

Closed mvollmer closed 1 week ago

mvollmer commented 3 weeks ago

Descriptions longer than about 128KiB will crash the Cockpit session with a protocol error since they are included in the open message for a "spawn" channel.

Only use the first 32k (about) when setting them to avoid that.

Fixes #1889
