Description Steve Whitehouse 2017-11-03 10:54:35 UTC

Add the ability to specify multiple IP addresses per node for the TCP transport so that multi-homed configurations can use any of a set of IP addresses as a source address and still be recognised by the receiving node. Currently we only support a single source IP address per node when accepting connections.

This will allow support of a wider variety of network configurations.

This will likely need some userland changes too, but for the time being I've only opened a kernel bug to track this item. We can clone more bugs later as required, but this is enough to have a placeholder and a location for any discussion.

Comment 1 Mark Ferrell 2017-11-28 21:07:25 UTC

Is this envisioned as a potential multipath (with a connection per IP) or as a method by which to attempt to reestablish a lost connection with a node and possible round-robin through available IPs?

Comment 2 Steve Whitehouse 2017-11-29 09:36:08 UTC

The connection re-establishment is covered in other bugs. This is just to allow the use of multiple IPs per node, which will allow a wider set of network configs. The intention is that they could be used in combination of course.

Comment 3 Steve Whitehouse 2018-03-26 13:28:46 UTC

I'm guessing that this one should be a reasonable target for 7.6 ?
