This patch adds block cipher algorithms for cbc(aes) and ecb(aes) for the PadLock device. Once all users to the old cipher type have been converted the old cbc/ecb PadLock operations will be removed. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

Some VIA processors come with an integrated crypto engine
|
|
(so called VIA PadLock ACE, Advanced Cryptography Engine)
|
|
that provides instructions for very fast cryptographic
|
|
operations with supported algorithms.
|
|
|
|
The instructions are used only when the CPU supports them.
|
|
Otherwise software encryption is used.
|
|
|
|
Selecting M for this option will compile a helper module
|
|
padlock.ko that should autoload all below configured
|
|
algorithms. Don't worry if your hardware does not support
|
|
some or all of them. In such case padlock.ko will
|
|
simply write a single line into the kernel log informing
|
|
about its failure but everything will keep working fine.
|
|
|
|
If you are unsure, say M. The compiled module will be
|
|
called padlock.ko
