crypto: Replaced gcc specific attributes with macros from compiler.h

2017-01-12T16:24:39+00:00

Continuing from this commit: 52f5684c8e1e
("kernel: use macros from compiler.h instead of __attribute__((...))")

I submitted 4 total patches. They are part of task I've taken up to
increase compiler portability in the kernel. I've cleaned up the
subsystems under /kernel /mm /block and /security, this patch targets
/crypto.

There is  which provides macros for various gcc specific
constructs. Eg: __weak for __attribute__((weak)). I've cleaned all
instances of gcc specific attributes with the right macros for the crypto
subsystem.

I had to make one additional change into compiler-gcc.h for the case when
one wants to use this: __attribute__((aligned) and not specify an alignment
factor. From the gcc docs, this will result in the largest alignment for
that data type on the target machine so I've named the macro
__aligned_largest. Please advise if another name is more appropriate.

crypto: aead - Add skcipher null for IV generators

2016-07-18T09:35:42+00:00

This patch adds an skcipher null object alongside the existing
null blkcipher so that IV generators using it can switch over
to skcipher.

crypto: aead - Add chunk size

2016-07-18T09:35:38+00:00

This patch adds a chunk size parameter to aead algorithms, just
like the chunk size for skcipher algorithms.

However, unlike skcipher we do not currently export this to AEAD
users.  It is only meant to be used by AEAD implementors for now.

2015-08-17T08:53:44+00:00

This patch adds the helpers aead_init_geniv and aead_exit_geniv
which are type-safe and intended the replace the existing geniv

crypto: aead - Add type-safe function for freeing instances

2015-07-14T06:56:45+00:00

This patch adds a type-safe function for freeing AEAD instances
to struct aead_instance.  This replaces the existing free function
in struct crypto_template which does not know the type of the
instance that it's freeing.

crypto: aead - Add multiple algorithm registration interface

2015-06-03T02:48:35+00:00

This patch adds the helpers that allow the registration and removal
of multiple algorithms.
