crypto: api - Introduce notifier for new crypto algorithms

2018-09-04T03:37:04+00:00

Introduce a facility that can be used to receive a notification
callback when a new algorithm becomes available. This can be used by
existing crypto registrations to trigger a switch from a software-only
algorithm to a hardware-accelerated version.

A new CRYPTO_MSG_ALG_LOADED state is introduced to the existing crypto
notification chain, and the register/unregister functions are exported
so they can be called by subsystems outside of crypto.

crypto: api - Make crypto_alg_lookup static

2018-03-30T17:32:58+00:00

The function crypto_alg_lookup is only usd within the crypto API
and should be not be exported to the modules.  This patch marks
it as a static function.

crypto: algapi - remove unused notifications

2018-01-05T07:43:10+00:00

There is a message posted to the crypto notifier chain when an algorithm
is unregistered, and when a template is registered or unregistered.  But
nothing is listening for those messages; currently there are only
listeners for the algorithm request and registration messages.

Get rid of these unused notifications for now.

crypto: algapi - convert cra_refcnt to refcount_t

2018-01-05T07:43:09+00:00

Reference counters should use refcount_t rather than atomic_t, since the
refcount_t implementation can prevent overflows, reducing the
exploitability of reference leak bugs.  crypto_alg.cra_refcount is a
reference counter with the usual semantics, so switch it over to
refcount_t.

crypto: api - Unexport crypto_larval_lookup()

2017-12-22T08:29:06+00:00

crypto_larval_lookup() is not used outside of crypto/api.c, so unexport
it and mark it 'static'.

crypto: api - Remove no-op exit_ops code

2016-10-21T03:03:42+00:00

crypto_exit_cipher_ops() and crypto_exit_compress_ops() are no-ops and
have been for a long time, so remove them.

crypto: api - Add crypto_type_has_alg helper

2016-01-25T14:42:12+00:00

This patch adds the helper crypto_type_has_alg which is meant
to replace crypto_has_alg for new-style crypto types.  Rather
than hard-coding type/mask information they're now retrieved
from the crypto_type object.

crypto: api - Remove linux/fips.h from internal.h

2015-04-23T06:18:10+00:00

Now that all fips_enabled users are including linux/fips.h directly
instead of getting it through internal.h, we can remove the fips.h
inclusions from internal.h.

crypto: api - Add crypto_alg_extsize helper

2015-04-21T02:19:54+00:00

This patch adds a crypto_alg_extsize helper that can be used
by algorithm types such as pcompress and shash.
