[Qemu-block] [PATCH v5 0/7] Add new LUKS block driver (for 2.6)

[Daniel P. Berrange]

This series is just the block layer parts needed to add
a LUKS driver to QEMU. It was previously posted as part
of the larger series

  v1: https://lists.gnu.org/archive/html/qemu-devel/2015-11/msg04748.html
  v2: https://lists.gnu.org/archive/html/qemu-block/2016-01/msg00534.html
  v3: https://lists.gnu.org/archive/html/qemu-devel/2016-02/msg03176.html
  v4: https://lists.gnu.org/archive/html/qemu-devel/2016-02/msg06552.html

The crypto subsystem pieces that this series depends on have
been submitted for merge

  https://lists.gnu.org/archive/html/qemu-devel/2016-03/msg04371.html

In this posting I am only proposing merge of the generic
LUKS driver. This can be added as a layer above any of the
existing drivers for accessing LUKS formatted volumes.

When creating new volumes, however, only the file backend
can be used, since the block driver API doesn't allow for
arbitrary stacking of protocols when creating images.

The integration with the qcow2 driver to replace the existing
built-in AES-CBC code is dropped from this series, postponed
until the 2.7 development cycle.

There is a QEMU I/O test 149 that exercises the LUKS driver
and checks for compatibility with the dm-crypt/cryptsetup
impl.


Daniel P. Berrange (7):
  block: add flag to indicate that no I/O will be performed
  qemu-img/qemu-io: don't prompt for passwords if not required
  tests: redirect stderr to stdout for iotests
  tests: refactor python I/O tests helper main method
  tests: add output filter to python I/O tests helper
  block: add generic full disk encryption driver
  block: drop support for using qcow[2] encryption with system emulators
