2017-07-11	qcow: convert QCow to use QCryptoBlock for encryption	Daniel P. Berrange	1	-5/+15
	This converts the qcow driver to make use of the QCryptoBlock APIs for encrypting image content. This is only wired up to permit use of the legacy QCow encryption format. Users who wish to have the strong LUKS format should switch to qcow2 instead. With this change it is now required to use the QCryptoSecret object for providing passwords, instead of the current block password APIs / interactive prompting. $QEMU \ -object secret,id=sec0,file=/home/berrange/encrypted.pw \ -drive file=/home/berrange/encrypted.qcow,encrypt.format=aes,\ encrypt.key-secret=sec0 Though note that running QEMU system emulators with the AES encryption is no longer supported, so while the above syntax is valid, QEMU will refuse to actually run the VM in this particular example. Likewise when creating images with the legacy AES-CBC format qemu-img create -f qcow \ --object secret,id=sec0,file=/home/berrange/encrypted.pw \ -o encrypt.format=aes,encrypt.key-secret=sec0 \ /home/berrange/encrypted.qcow 64M Reviewed-by: Max Reitz <mreitz@redhat.com> Reviewed-by: Alberto Garcia <berto@igalia.com> Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P.

2017-07-11	block: add ability to set a prefix for opt names	Daniel P. Berrange	1	-20/+20
	When integrating the crypto support with qcow/qcow2, we don't want to use the bare LUKS option names "hash-alg", "key-secret", etc. We need to namespace them to match the nested QAPI schema. e.g. "encrypt.hash-alg", "encrypt.key-secret" so that they don't clash with any general qcow options at a later date.

2017-07-11	block: expose crypto option names / defs to other drivers	Daniel P. Berrange	1	-0/+91
	The block/crypto.c defines a set of QemuOpts that provide parameters for encryption. This will also be needed by the qcow/qcow2 integration, so expose the relevant pieces in a new block/crypto.h header. Some helper methods taking QemuOpts are changed to take QDict to simplify usage in other places.
