From 41581265aa83127036e4f2d6417820f59276514b Mon Sep 17 00:00:00 2001 From: Zongmin Zhou Date: Mon, 20 Nov 2023 11:14:28 +0800 Subject: [PATCH] migration: free 'saddr' since be no longer used MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Since socket_parse() will allocate memory for 'saddr',and its value will pass to 'addr' that allocated by migrate_uri_parse(), then 'saddr' will no longer used,need to free. But due to 'saddr->u' is shallow copying the contents of the union, the members of this union containing allocated strings,and will be used after that. So just free 'saddr' itself without doing a deep free on the contents of the SocketAddress.
