As only one place in vhost-scsi.c uses DEFINE_VHOST_SCSI_PROPERTIES, there is no need to expose it. Inline it into vhost-scsi.c to avoid wrongly use.

Make features 64bit wide everywhere. On migration a full 64bit guest_features field is sent if one of the high bits is set, in addition to the lower 32bit guest_features field which must stay for compatibility reasons. That way we send the lower 32 feature bits twice, but the code is simpler because we don't have to split and compose the 64bit features into two 32bit fields.

monitor_handle_fd_param() is a wrapper around monitor_handle_fd_param2() that feeds errors to qerror_report_err() instead of returning them. qerror_report_err() is inappropriate in many contexts. monitor_handle_fd_param() looks simpler than monitor_handle_fd_param2(), which tempts use. Remove the temptation: drop the wrapper and open-code the (trivial) error handling instead. Replace the open-coded qerror_report_err() by error_report_err() in places that already use error_report(). Turns out that's everywhere. While there, rename monitor_handle_fd_param2() to monitor_fd_param(). Signed-off-by: NMarkus Armbruster <armbru@redhat.com> Reviewed-by: NEric Blake <eblake@redhat.com>

We get two error messages: one from monitor_handle_fd_param2(), and another one from vhost_scsi_realize(). The second one gets suppressed in QMP context. That's because monitor_handle_fd_param() calls qerror_report_err(). Calling qerror_report_err() is always inappropriate in realize methods, because it doesn't return the Error object. It either reports the error to stderr or the human monitor, or it stores it in the QMP monitor, where it makes the QMP command fail even when the realize method ignores the error and succeeds. Fortunately, vhost_scsi_realize() doesn't do that. Fix by switching to monitor_handle_fd_param2(). Signed-off-by: NMarkus Armbruster <armbru@redhat.com> Acked-by: NPaolo Bonzini <pbonzini@redhat.com>

As vhost core can use backend_features during init, clear it earlier to avoid using uninitialized memory. This use would be harmless since vhost scsi ignores the result anyway, but initializing earlier will help prevent valgrind errors, and make scsi and net behave similarly.

vhost_dev_init will replace devfd and devpath with a single opaque argument. This is initialised with a file descriptor. When TAP is used (through vhost_net), open /dev/vhost-net and pass the fd as an opaque parameter in VhostNetOptions. The same applies to vhost-scsi - open /dev/vhost-scsi and pass the fd.

vhost userspace needn't to handle vq's notification from guest, so define dummy handle_output callback for all vqs of vhost-scsi. In some corner cases(such as when handling vq's reset from VM), virtio-pci still trys to handle pending virtio-scsi events, then object check failure inside virtio_scsi_handle_event() for vhost-scsi can be triggered. The issue can be reproduced by 'rmmod virtio-scsi', 'system sleep' or reboot inside VM. Cc: qemu-stable@nongnu.org Cc: Anthony Liguori <aliguori@amazon.com> Cc: "Michael S.

The WWPN specified in configfs is passed to "-device vhost-scsi-pci". The tgpt field of the SET_ENDPOINT ioctl is obsolete now, so it is not available from the QEMU command-line.
