From 0c26f2eca40d6c65ea9edc62a10e510dc7f65cc8 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Mon, 26 Nov 2012 13:10:12 +0100 Subject: qapi: handle visitor->type_size() in QapiDeallocVisitor MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit visit_type_size() requires either visitor->type_size() or visitor_uint64() to be implemented, otherwise a NULL function pointer is invoked. It is possible to trigger this crash as follows: $ qemu-system-x86_64 -netdev tap,sndbuf=0,id=netdev0 \ -device virtio-blk-pci,netdev=netdev0 The 'sndbuf' option has type "size".
