[Qemu-devel] [PATCH 02/11] qemu-nbd: Improve error reporting

[Kevin Wolf]

From: Ryota Ozaki <ozaki.ryota@gmail.com>

- use err(3) instead of errx(3) if errno is available
  to report why failed
- let fail prior to daemon(3) if opening a nbd file
  is likely to fail after daemonizing to avoid silent
  failure exit
- add missing 'ret = 1' when unix_socket_outgoing failed

[Qemu-devel] [PATCH 04/11] cloop: use qemu block API

[Kevin Wolf]

From: Christoph Hellwig <hch@lst.de>

Use bdrv_pwrite to access the backing device instead of pread, and
convert the driver to implementing the bdrv_open method which gives
it an already opened BlockDriverState for the underlying device.

[Qemu-devel] [PATCH 05/11] ide: Fix ide_dma_cancel

[Kevin Wolf]

When cancelling a request, bdrv_aio_cancel may decide that it waits for
completion of a request rather than for cancellation. IDE therefore can't
abandon its DMA status before calling bdrv_aio_cancel; otherwise the callback
of a completed request would use invalid data.

[Qemu-devel] [PATCH 07/11] bochs: use qemu block API

[Kevin Wolf]

From: Christoph Hellwig <hch@lst.de>

Use bdrv_pwrite to access the backing device instead of pread, and
convert the driver to implementing the bdrv_open method which gives
it an already opened BlockDriverState for the underlying device.

[Qemu-devel] [PATCH 11/11] block/vdi: Allow disk images of size 0

[Kevin Wolf]

From: Stefan Weil <weil@mail.berlios.de>

Even it is not very useful, users may create images of size 0.

Without the special option CONFIG_ZERO_MALLOC, qemu_mallocz
aborts execution when it is told to allocate 0 bytes,
so avoid this kind of call.

Yep, that worked fine: I've applied that.

Please update the changelog at https://wiki.qemu.org/ChangeLog/4.1
for any user-visible changes.

(Strace says that we seem to successfully connect to
the git.xanclic.moe server and do some talking to it,
but the first time the client issues a "fetch" command
the server never replies and the client is just blocked
in read().)

Self-NACK.  Sorry, I don't quite know how the locking fix slipped in
there, but it shouldn't be here.

 * Copy offloading for qemu-img convert (iSCSI, raw, and qcow2)

   If the underlying storage supports copy offloading, qemu-img convert will
   use it instead of performing reads and writes.  This avoids data transfers
   and thus frees up storage bandwidth for other purposes.  SCSI EXTENDED COPY
   and Linux copy_file_range(2) are used to implement this optimization.

 * Drop spurious "WARNING: I\/O thread spun for 1000 iterations" warning

----------------------------------------------------------------

Fam Zheng (10):
  block: Introduce API for copy offloading
  raw: Check byte range uniformly
  raw: Implement copy offloading
  qcow2: Implement copy offloading
  file-posix: Implement bdrv_co_copy_range
  iscsi: Query and save device designator when opening
  iscsi: Create and use iscsi_co_wait_for_task
  iscsi: Implement copy offloading
  block-backend: Add blk_co_copy_range
  qemu-img: Convert with copy offloading

I think all of your suggestions would be appropriate, even though most
of them fix rather theoretical cases.

Are any of these appropriate for -stable?  I think some are, below:

This?  Appears to be a minor case.

Most likely this.  Jason?

This, but does anyone really use sheepdog with savevm/loadvm?
Probably a very minor issue too, not worth -stable.

And this,

And probably this too?  I'm not sure about this one.
