From 9ed40766735a9628cc6c936076b175e6f66534bb Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Fri, 30 May 2014 11:33:01 +0300 Subject: [PATCH] RADIUS client: Do not try to send message without socket It is possible for the RADIUS authentication/accounting socket to not be open even if partial RADIUS server configuration has been done through the control interface SET commands. Previously, this resulted in send() attempt using fd=-1 which fails with bad file descriptor. Clean this up by logging this as a missing configuration instead of trying to send the message when that is known to fail.
