Generally, you can create UNIX domain sockets in the global zone, and if you
put the path to them in a filesystem that is mounted inside the local zone,
then that local zone will be able to attach. This is a kind of way to enable
communication between the GZ and the local zone.
Note that generally zones don’t share filesystems, so typically you can’t use
this to get between to distinct local zones. There may be some tricks to make
even that work, but to be honest I’ve not tried — it seems like it would be a
bad idea.
(One weird and random idea I just had — could you do a socketpair in the GZ,
and then exec from two separate forked children, into the zone. I’m not sure
that there is a public API for exec’ing into the context of a specific zone
though.)
