crypto: cryptd - Use crypto_grab_aead

2015-05-22T03:25:49+00:00

As AEAD has switched over to using frontend types, the function
crypto_init_spawn must not be used since it does not specify a
frontend type.  Otherwise it leads to a crash when the spawn is
used.

This patch fixes it by switching over to crypto_grab_aead instead.

crypto: cryptd - Use crypto_aead_set_reqsize helper

2015-05-13T02:31:40+00:00

This patch uses the crypto_aead_set_reqsize helper to avoid directly
touching the internals of aead.

crypto: cryptd - process CRYPTO_ALG_INTERNAL

2015-03-31T13:21:04+00:00

The cryptd is used as a wrapper around internal ciphers. Therefore, the
cryptd must process the internal cipher by marking cryptd as internal if
the underlying cipher is an internal cipher.

crypto: include crypto- module prefix in template

2014-11-26T12:06:30+00:00

This adds the module loading prefix "crypto-" to the template lookup
as well.

For example, attempting to load 'vfat(blowfish)' via AF_ALG now correctly
includes the "crypto-" prefix at every level, correctly rejecting "vfat":

	net-pf-38
	algif-hash
	crypto-vfat(blowfish)
	crypto-vfat(blowfish)-all
	crypto-vfat

Change formal parameters to not clash with global names to
eliminate many W=2 warnings.

crypto: cryptd - disable softirqs in cryptd_queue_worker to prevent data corruption

2012-10-24T13:21:18+00:00

cryptd_queue_worker attempts to prevent simultaneous accesses to crypto
workqueue by cryptd_enqueue_request using preempt_disable/preempt_enable.
However cryptd_enqueue_request might be called from softirq context,
so add local_bh_disable/local_bh_enable to prevent data corruption and
panics.

v2:
 - Disable software interrupts instead of hardware interrupts

crypto: cryptd - Use subsys_initcall to prevent races with aesni

2011-08-20T08:08:03+00:00

As cryptd is depeneded on by other algorithms such as aesni-intel,
it needs to be registered before them.  When everything is built
as modules, this occurs naturally.  However, for this to work when
they are built-in, we need to use subsys_initcall in cryptd.

crypto: cryptd - Adding the AEAD interface type support to cryptd

2010-09-20T08:05:12+00:00

This patch adds AEAD support into the cryptd framework. Having AEAD
support in cryptd enables crypto drivers that use the AEAD
interface type (such as the patch for AEAD based RFC4106 AES-GCM
implementation using Intel New Instructions) to leverage cryptd for
asynchronous processing.
