cache=unsafe completely ignored bdrv_flush, because flushing the host disk costs a lot of performance. However, this means that qcow2 images (and potentially any other format) can lose data even after the guest has issued a flush if the qemu process crashes/is killed. In case of a host crash, data loss is certainly expected with cache=unsafe, but if just the qemu process dies this is a bit too unsafe. Now that we have two separate flush functions, we can choose to flush everythign to the OS, but don't enforce that it's physically written to the disk. Signed-off-by: NKevin Wolf <kwolf@redhat.com>

qcow2 has a writeback metadata cache, so flushing a qcow2 image actually consists of writing back that cache to the protocol and only then flushes the protocol in order to get everything stable on disk. This introduces a separate bdrv_co_flush_to_os to reflect the split. Signed-off-by: NKevin Wolf <kwolf@redhat.com>

There are two different types of flush that you can do: Flushing one level up to the OS (i.e. writing data to the host page cache) or flushing it all the way down to the disk. The existing functions flush to the disk, reflect this in the function name. Signed-off-by: NKevin Wolf <kwolf@redhat.com>

Fix a use-while-uninitialized of the fd_type[] array (introduced in commit 34d4260e, noticed by Coverity).

The Data Offset field in the Dynamic Disk Header is an 8 byte field. Although the specification (2006-10-11) gives an example of initializing only the first 4 bytes, images generated by Microsoft on Windows initialize all 8 bytes. Failure to initialize all 8 bytes results in errors from utilities like Citrix's vhd-util which checks specifically for the proper Data Offset field initialization.

This is cleaner, because we do not need to close the block device when there is an error opening /dev/nbdX. It was done this way only to print errors before daemonizing.

Now that the client and server are in the same process, there is no need to race on the creation of the socket. We can open the listening socket before starting the client thread. This avoids that "qemu-nbd -v -c" prints this once before connecting successfully to the socket: connect(unix:/var/lock/qemu-nbd-nbd0): No such file or directory Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

In order to get nice error messages, keep the qemu-nbd process running until before issuing NBD_DO_IT and connected to the daemon with a pipe. This lets the qemu-nbd process relay error messages from the daemon and exit with a nonzero status if appropriate.

This avoids that qemu-nbd uses both forking and threads, which do not behave well together. qemu-nbd is already Unix only, and there is no qemu_thread_join, so for now use pthreads. Since the parent and child no longer have separate file descriptors, we can open the NBD device before daemonizing, instead of checking with access(2) and restricting the open to the client only.

The client process right now uses SIGTERM to interrupt the server side. This does not affect the exit status of "qemu-nbd -v -c" because the server is a child process. This will change when both sides will be in the same process, and anyway cleaning up things nicely upon SIGTERM is good practice.
