From 9ee8a692f1da77d798842fdc1e0dc2a5ff0fc0c1 Mon Sep 17 00:00:00 2001 From: Emanuele Giuseppe Esposito Date: Tue, 26 Jun 2018 16:18:53 +0200 Subject: [PATCH] vhost-user-test: added proper TestServer *dest initialization in test_migrate() server->bus in _test_server_free() could be NULL, since TestServer *dest in test_migrate() was not properly initialized like TestServer *s. Added init_virtio_dev(dest) and uninit_virtio_dev(dest), so the fields are properly set and when test_server_free(dest); is called, they can be correctly freed. The reason for that is init_virtio_dev() calls qpci_init_pc(), that creates a QPCIBusPC * (returned as QPCIBus *), while test_server_free() calls qpci_free_pc(), that frees the QPCIBus *. Not calling init_virtio_dev() would leave the QPCIBus * of TestServer unset. Problem came out once I modified pci-pc.c and pci-pc.h, modifying QPCIBusPC by adding another field before QPCIBus bus. Re-running the tests showed vhost-user-test failing.
