From 0bacc71fc208e5cdf0727de027438b8e901ff666 Mon Sep 17 00:00:00 2001 From: Harald Welte Date: Sat, 8 Apr 2017 22:09:57 +0200 Subject: stream/datagram: Consistently use osmo_talloc_replace_string() during osmo_*_set_addr(), we must make sure to talloc_free() any old address before copying in the new address. Not all functions did this, and those that did implemented it manually. Let's use osmo_talloc_replace_string() which is exactly intended for this case.
