From 0cfc0cd32239d3c08d2121e028b297022450b320 Mon Sep 17 00:00:00 2001 From: Vasil Dimov Date: Sun, 18 Oct 2020 14:45:35 +0200 Subject: net: fix GetListenPort() to derive the proper port `GetListenPort()` uses a simple logic: "if `-port=P` is given, then we must be listening on `P`, otherwise we must be listening on `8333`". This is however not true if `-bind=` has been provided with `:port` part or if `-whitebind=` has been provided. Thus, extend `GetListenPort()` to return the port from `-bind=` or `-whitebind=`, if any.
