crypto: algif_skcipher - User-space interface for skcipher operations
This patch adds the af_alg plugin for symmetric key ciphers,
corresponding to the ablkcipher kernel operation type.
Keys can optionally be set through the setsockopt interface.

The test program below runs 1000 encryptions:
# grep nr_free /proc/vmstat
nr_free_pages 11031
# ./test
...
# grep nr_free /proc/vmstat
nr_free_pages 10026

Hi Herbert,
I did a proof-of-concept implementation for our crypto library, the
interface looks good so far. All our hash, hmac, xcbc and cipher test
vectors matched.

Every skcipher operation leaks memory on my box (this pag
