Hi, You need this fix:
https://sourceforge.net/p/tipc/mailman/message/34768934/ But it wont apply cleanly, so you need this entire series to fix all issues related to topology server. https://sourceforge.net/p/tipc/mailman/message/34768927/ They were too intrusive to be pushed to net, hence were pushed to net-next and were merged in 4.7. /Partha On 09/01/2016 08:43 PM, Jon Maloy wrote: > Hi Jonas, > I don’t think there is any such thing as a “long-term” kernel from the > community viewpoint.
