From 0e79668e1ffcfabb259bea6c2a2bae00a6b27252 Mon Sep 17 00:00:00 2001 From: zhanghailiang Date: Tue, 28 Feb 2017 11:54:18 +0800 Subject: [PATCH] net/colo: fix memory double free error The 'primary_list' and 'secondary_list' members of struct Connection is not allocated through dynamically g_queue_new(), but we free it by using g_queue_free(), which will lead to a double-free bug.
