* Adjust crypto_apply function callbacks for OCF.John Baldwin2020-06-101-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | - crypto_apply() is only used for reading a buffer to compute a digest, so change the data pointer to a const pointer. - To better match m_apply(), change the data pointer type to void * and the length from uint16_t to u_int. The length field in particular matters as none of the apply logic was splitting requests larger than UINT16_MAX. - Adjust the auth_xform Update callback to match the function prototype passed to crypto_apply() and crypto_apply_buf(). This removes the needs for casts when using the Update callback. - Change the Reinit and Setkey callbacks to also use a u_int length instead of uint16_t. - Update auth transforms for the changes. While here, use C99 initializers for auth_hash structures and avoid casts on callbacks.

* Add CBC-MAC authentication.Sean Eric Fagan2019-02-151-0/+67
This adds the CBC-MAC code to the kernel, but does not hook it up to anything (that comes in the next commit). https://tools.ietf.org/html/rfc3610 describes the algorithm. Note that this is a software-only implementation, which means it is fairly slow.
