From 89c568489122de996920b760c34e81b925cc8181 Mon Sep 17 00:00:00 2001 From: "Dr. David Alan Gilbert" Date: Thu, 13 Jan 2022 19:44:51 +0000 Subject: migration: Add canary to VMSTATE_END_OF_LIST MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We fairly regularly forget VMSTATE_END_OF_LIST markers off descriptions; given that the current check is only for ->name being NULL, sometimes we get unlucky and the code apparently works and no one spots the error. Explicitly add a flag, VMS_END that should be set, and assert it is set during the traversal. Note: This can't go in until we update the copy of vmstate.h in slirp.
