+From 5e3704dd850a5df2fb2b3eafd117963d017d07b4 Mon Sep 17 00:00:00 2001
+From: "Bruce A. Mah" <bmah@es.net>
+Date: Tue, 1 Aug 2023 14:02:54 -0700
+Subject: [PATCH] Implement fixes to make the control connection more robust.
+
+These include various timeouts in Nread() to guarantee that it will
+eventually exit, a 10-second timeout for each attempt to read data
+from the network and an approximately 30-second overall timeout per
+Nread() call.
+
+Also the iperf3 server now checks the length of the received session
+cookie, and errors out if this happens to be incorrect.
+
+Reported by Jorge Sancho Larraz - Canonical.
