From f1dc67d0e7df21b3d27beb3ec7b2c9e2b721daff Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Sat, 25 May 2019 00:08:43 +0200 Subject: um: Add an option to make serial driver non-raw In some cases, for example when the program(s) running inside UML isn't/aren't interactive (like the hwsim tests for wpa_supplicant) there's really no value in having the serial lines configured to be raw as they are now by default. Setting them to non-raw lets one abort the whole UML with Ctrl-C, which is really the right thing to do in these cases, basically the whole UML instance is more like a single (testing) program. Add a "ssl-non-raw" option to UML to support such a mode.
