From 8db804ac412010fc96397c2d67ee6417eccd9d34 Mon Sep 17 00:00:00 2001 From: Gonglei Date: Thu, 20 Nov 2014 19:35:01 +0800 Subject: net/socket: fix Uninitialized scalar variable If is_connected parameter is false, the saddr variable will no initialize. Coverity report: uninit_use: Using uninitialized value saddr.sin_port. We don't need add saddr information to nc->info_str when is_connected is false.
