From fdb3accc2c15fabc2b687b2819da9167027c61b6 Mon Sep 17 00:00:00 2001 From: Richard Alpe Date: Fri, 26 Aug 2016 10:52:55 +0200 Subject: tipc: add the ability to get UDP options via netlink Add UDP bearer options to netlink bearer get message. This is used by the tipc user space tool to display UDP options. The UDP bearer information is passed using either a sockaddr_in or sockaddr_in6 structs. This means the user space receiver should intermediately store the retrieved data in a large enough struct (sockaddr_strage) before casting to the proper IP version type.
