File virtio-crypto-do-delete-ctrl_vq-in-virti.patch of Package qemu
From: Pan Nengyuan <pannengyuan@huawei.com> Date: Tue, 25 Feb 2020 15:55:54 +0800 Subject: virtio-crypto: do delete ctrl_vq in virtio_crypto_device_unrealize Git-commit: d56e1c8256cb37e68f9b5d98c6cc4e6ca463f1fd Similar to other virtio-deivces, ctrl_vq forgot to delete in virtio_crypto_device_unrealize, this patch fix it. This device has aleardy maintained vq pointers. Thus, we use the new virtio_delete_queue function directly to do the cleanup. The leak stack: Direct leak of 10752 byte(s) in 3 object(s) allocated from: #0 0x7f4c024b1970 in __interceptor_calloc (/lib64/libasan.so.5+0xef970) #1 0x7f4c018be49d in g_malloc0 (/lib64/libglib-2.0.so.0+0x5249d) #2 0x55a2f8017279 in virtio_add_queue /mnt/sdb/qemu-new/qemu_test/qemu/hw/virtio/virtio.c:2333 #3 0x55a2f8057035 in virtio_crypto_device_realize /mnt/sdb/qemu-new/qemu_test/qemu/hw/virtio/virtio-crypto.c:814 #4 0x55a2f8005d80 in virtio_device_realize /mnt/sdb/qemu-new/qemu_test/qemu/hw/virtio/virtio.c:3531 #5 0x55a2f8497d1b in device_set_realized /mnt/sdb/qemu-new/qemu_test/qemu/hw/core/qdev.c:891 #6 0x55a2f8b48595 in property_set_bool /mnt/sdb/qemu-new/qemu_test/qemu/qom/object.c:2238 #7 0x55a2f8b54fad in object_property_set_qobject /mnt/sdb/qemu-new/qemu_test/qemu/qom/qom-qobject.c:26 #8 0x55a2f8b4de2c in object_property_set_bool /mnt/sdb/qemu-new/qemu_test/qemu/qom/object.c:1390 #9 0x55a2f80609c9 in virtio_crypto_pci_realize /mnt/sdb/qemu-new/qemu_test/qemu/hw/virtio/virtio-crypto-pci.c:58 Reported-by: Euler Robot <euler.robot@huawei.com> Signed-off-by: Pan Nengyuan <pannengyuan@huawei.com> Cc: "Gonglei (Arei)" <arei.gonglei@huawei.com> Message-Id: <20200225075554.10835-5-pannengyuan@huawei.com> Reviewed-by: Michael S.
