[PATCH 0/5] RFC: connector: Add network namespace awareness

From: Matt Bennett
Date: Wed Jul 01 2020 - 20:27:51 EST


Previously the connector functionality could only be used by processes running in the
default network namespace. This meant that any process that uses the connector functionality
could not operate correctly when run inside a container. This is a draft patch series that
attempts to now allow this functionality outside of the default network namespace.

I see this has been discussed previously [1], but am not sure how my changes relate to all
of the topics discussed there and/or if there are any unintended side effects from my draft
changes.

Thanks.
