From 832629ca5c313e122b22b8e73a6d80f111b1a1ae Mon Sep 17 00:00:00 2001 From: Richard Alpe Date: Fri, 26 Aug 2016 10:52:56 +0200 Subject: tipc: add UDP remoteip dump to netlink API When using replicast a UDP bearer can have an arbitrary amount of remote ip addresses associated with it. This means we cannot simply add all remote ip addresses to an existing bearer data message as it might fill the message, leaving us with a truncated message that we can't safely resume. To handle this we introduce the new netlink command TIPC_NL_UDP_GET_REMOTEIP. This command is intended to be called when the bearer data message has the TIPC_NLA_UDP_MULTI_REMOTEIP flag set, indicating there are more than one remote ip (replicast).
