From e18f6133b254db9e1dc7b202366b067b15a68123 Mon Sep 17 00:00:00 2001 From: David Kalnischkies Date: Wed, 10 Dec 2014 22:26:59 +0100 Subject: do not make PTY slave the controlling terminal MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit If we have no controlling terminal opening a terminal will make this terminal our controller, which is a serious problem if this happens to be the pseudo terminal we created to run dpkg in as we will close this terminal at the end hanging ourself up in the process… The offending open is the one we do to have at least one slave fd open all the time, but for good measure, we apply the flag also to the slave fd opening in the child process as we set the controlling terminal explicitely here. This is a regression from 150bdc9ca5d656f9fba94d37c5f4f183b02bd746 with the slight twist that this usecase was silently broken before in that it wasn't logging the output in term.log (as a pseudo terminal wasn't created).
