Author: kevlo Date: Mon Aug 8 05:25:51 2011 New Revision: 224703 URL: http://svn.freebsd.org/changeset/base/224703 Log: In rtinit1(), before rtrequest1_fib() is called, info.rti_flags is initialized by flags (function argument) or-ed with ifa->ifa_flags. If both NIC has a loopback route to itself, so IFA_RTSELF is set on ifa(s). As IFA_RTSELF is defined by RTF_HOST, rtrequest1_fib() is called with RTF_HOST flag even if netmask is not NULL. Consequently, netmask is set to zero in rtrequest1_fib(), and request to add network route is changed under hands to request to add host route.
