From cccbc0151883cfb4f43d6fa0a4a3caedc27e6cf5 Mon Sep 17 00:00:00 2001 From: Paul Jakma Date: Thu, 14 Jun 2012 10:40:26 +0100 Subject: bgpd: Add "no listen" socket option for the BGP master configuration * bgpd.h: add a BGP_OPT_NO_LISTEN option for the master BGP configuration, to prevent any listen socket being created automatically. Allows code to be used outside of BGP daemon settings. * bgpd.c: (bgp_get) honour above the flag, suppress auto-creation of listen socket on first BGP instance if set.
