Ilya Dryomov b16d0c5d32 libceph: implement CEPHX_V2 calculation mode 
commit cc255c76c70f7a87d97939621eae04b600d9f4a1 upstream.

Derive the signature from the entire buffer (both AES cipher blocks)
instead of using just the first half of the first block, leaving out
data_crc entirely.

This addresses CVE-2018-1129.

* Notes on deprecation:
*
* A *major* release is a release through which all upgrades must pass
* (e.g., jewel). For example, no pre-jewel server will ever talk to
* a post-jewel server (mon, osd, etc).
*
* For feature bits used *only* on the server-side:
*
* - In the first phase we indicate that a feature is DEPRECATED as of
* a particular release. This is the first major release X (say,
* jewel) that does not depend on its peers advertising the feature.
* That is, it safely assumes its peers all have the feature. We
* indicate this with the DEPRECATED macro. For example,
*
* DEFINE_CEPH_FEATURE_DEPRECATED( 2, 1, MONCLOCKCHECK, JEWEL)
*
* because 10.2.z (jewel) did not care if its peers advertised this
* feature bit.
*
* - In the second phase we stop advertising the the bit and call it
* RETIRED. This can normally be done in the *next* major release
* following the one in which we marked the feature DEPRECATED. In
* the above example, for 12.0.z (luminous) we can say:
*
* DEFINE_CEPH_FEATURE_RETIRED( 2, 1, MONCLOCKCHECK, JEWEL, LUMINOUS)
*
* - The bit can be reused in the first post-luminous release, 13.0.z
* (m).
*
* This ensures that no two versions who have different meanings for
* the bit ever speak to each other.
