From e00c024230e457a0f37ea5c90bd8caac0c30020e Mon Sep 17 00:00:00 2001 From: Wolfgang Bumiller Date: Thu, 28 Jul 2016 11:52:18 +0200 Subject: [PATCH] conf: set pty_info to NULL after free This fixes a double free corruption on container-requested reboots when lxc_spawn() fails before receiving the ttys, as lxc_fini() (part of __lxc_start()'s cleanup) calls lxc_delete_tty().
