From f9a8b5530d438f836f9697639814f585aaec554d Mon Sep 17 00:00:00 2001 From: Eduardo Habkost Date: Thu, 28 Jan 2016 12:22:35 -0200 Subject: qdev: Use GList for global properties If the same GlobalProperty struct is registered twice, the list entry gets corrupted, making tqe_next points to itself, and qdev_prop_set_globals() gets stuck in a loop. The bug can be easily reproduced by running: $ qemu-system-x86_64 -rtc-td-hack -rtc-td-hack Change global_props to use GList instead of queue.h, making the code simpler and able to deal with properties being registered twice.
