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.
