* block: pass option prefix down to crypto layerDaniel P. Berrange2017-07-111-0/+2
| | | | | | | | | | | | | | | While the crypto layer uses a fixed option name "key-secret", the upper block layer may have a prefix on the options. e.g. "encrypt.key-secret", in order to avoid clashes between crypto option names & other block option names. To ensure the crypto layer can report accurate error messages, we must tell it what option name prefix was used.

* crypto: add support for querying parameters for block encryptionDaniel P. Berrange2016-07-261-0/+4
| | | | | | | | | | | | | When creating new block encryption volumes, we accept a list of parameters to control the formatting process. It is useful to be able to query what those parameters were for existing block devices. Add a qcrypto_block_get_info() method which returns a QCryptoBlockInfo instance to report this data.

* Clean up header guards that don't match their file nameMarkus Armbruster2016-07-121-3/+3
| | | | | | | | | | | | Header guard symbols should match their file name to make guard collisions less likely. Offenders found with scripts/clean-header-guards.pl -vn. Cleaned up with scripts/clean-header-guards.pl, followed by some renaming of new guard symbols picked by the script to better ones.

* crypto: add block encryption frameworkDaniel P. Berrange2016-03-171-0/+92
Add a generic framework for supporting different block encryption formats. Upon instantiating a QCryptoBlock object, it will read the encryption header and extract the encryption keys. It is then possible to call methods to encrypt/decrypt data buffers. There is also a mode whereby it will create/initialize a new encryption header on a previously unformatted volume. The initial framework comes with support for the legacy QCow AES based encryption. This enables code in the QCow driver to be consolidated later.
