The specification which crypto facility is required for an algorithm is added
as a parameter to the availability check which is done before an algorithm is
registered. With this change it is easier to add new algorithms that require
different facilities.Signed-off-by: Jan Glauber

The fallback code in cipher mode touch the union fallback.blk instead
of fallback.cip. This is wrong because we use the cipher and not the
blockcipher. This did not show any side effects yet because both types /
structs contain the same element right now.Signed-off-by: Roel Kluin

With the mandatory algorithm testing at registration, we have
now created a deadlock with algorithms requiring fallbacks.
This can happen if the module containing the algorithm requiring
fallback is loaded first, without the fallback module being loaded
first. The system will then try to test the new algorithm, find
that it needs to load a fallback, and then try to load that.As both algorithms share the same module alias, it can attempt
to load the original algorithm again and block indefinitely.As algorithms requiring fallbacks are a special case, we can fix
this by giving them a different module alias than the rest. Then
it's just a matter of using the right aliases according to what
algorithms we're trying to find.Signed-off-by: Herbert Xu

Some CPUs support only 128 bit keys in HW. This patch adds SW fallback
support for the other keys which may be required. The generic algorithm
(and the block mode) must be availble in case of a fallback.Signed-off-by: Sebastian Siewior

Loading the crypto algorithm by the alias instead of by module directly
has the advantage that all possible implementations of this algorithm
are loaded automatically and the crypto API can choose the best one
depending on its priority.Additionally it ensures that the generic implementation as well as the
HW driver (if available) is loaded in case the HW driver needs the
generic version as fallback in corner cases.Signed-off-by: Sebastian Siewior

This patch moves the config options for the s390 crypto instructions
to the standard "Hardware crypto devices" menu. In addition some
cleanup has been done: use a flag for supported keylengths, add a
warning about machien limitation, return ENOTSUPP in case the
hardware has no support, remove superfluous printks and update
email addresses.Signed-off-by: Jan Glauber

This patch removes obsolete block operations of the simple cipher type
from drivers. These were preserved so that existing users can make a
smooth transition. Now that the transition is complete, they are no
longer needed.Signed-off-by: Herbert Xu

This patch adds block cipher algorithms for S390. Once all users of the
old cipher type have been converted the existing CBC/ECB non-block cipher
operations will be removed.Signed-off-by: Herbert Xu

Accelerated versions of crypto algorithms must carry a distinct driver name

Now that the tfm is passed directly to setkey instead of the ctx, we no
longer need to pass the &tfm->crt_flags pointer.This patch also gets rid of a few unnecessary checks on the key length
for ciphers as the cipher layer guarantees that the key length is within
the bounds specified by the algorithm.Rather than testing dia_setkey every time, this patch does it only once
during crypto_alloc_tfm. The redundant check from crypto_digest_setkey
is also removed.Signed-off-by: Herbert Xu

Up until now algorithms have been happy to get a context pointer since
they know everything that's in the tfm already (e.g., alignment, block
size).However, once we have parameterised algorithms, such information will
be specific to each tfm. So the algorithm API needs to be changed to
pass the tfm structure instead of the context pointer.This patch is basically a text substitution. The only tricky bit is
the assembly routines that need to get the context pointer offset
through asm-offsets.h.Signed-off-by: Herbert Xu
