From: Sabrina Dubroca <s...@queasysnail.net> 3.12-stable review patch. If anyone has any objections, please let me know.
=============== [ Upstream commit c88507fbad8055297c1d1e21e599f46960cbee39 ] DST_NOCOUNT should only be used if an authorized user adds routes locally. In case of routes which are added on behalf of router advertisments this flag must not get used as it allows an unlimited number of routes getting added remotely.
