crypto: remove several VLAs

2018-04-20T16:58:34+00:00

We avoid various VLAs[1] by using constant expressions for block size
and alignment mask.

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 missing headers for setkey_unaligned

2007-10-10T23:55:40+00:00

This patch ensures that kernel.h and slab.h are included for
the setkey_unaligned function.  It also breaks a couple of
long lines.

[CRYPTO] api: fix writting into unallocated memory in setkey_aligned

2007-08-06T07:33:56+00:00

setkey_unaligned() commited in ca7c39385ce1a7b44894a4b225a4608624e90730
overwrites unallocated memory in the following memset() because
I used the wrong buffer length.

[CRYPTO] api: Handle unaligned keys in setkey

2007-07-11T12:58:54+00:00

setkey() in {cipher,blkcipher,ablkcipher,hash}.c does not respect the
requested alignment by the algorithm. This patch fixes it. The extra
memory is allocated by kmalloc() with GFP_ATOMIC flag.

[CRYPTO] api: Mark parts of cipher interface as deprecated

2006-09-21T01:46:16+00:00

Mark the parts of the cipher interface that have been replaced by
block ciphers as deprecated.  Thanks to Andrew Morton for suggesting
doing this before removing them completely.

[CRYPTO] scatterwalk: Prepare for block ciphers

2006-09-21T01:41:52+00:00

This patch prepares the scatterwalk code for use by the new block cipher
type.

Firstly it halves the size of scatter_walk on 32-bit platforms.  This
is important as we allocate at least two of these objects on the stack
for each block cipher operation.

It also exports the symbols since the block cipher code can be built as
a module.

Finally there is a hack in scatterwalk_unmap that relies on progress
being made.  Unfortunately, for hardware crypto we can't guarantee
progress to be made since the hardware can fail.

So this also gets rid of the hack by not advancing the address returned
by scatterwalk_map.

[CRYPTO] cipher: Added encrypt_one/decrypt_one

2006-09-21T01:41:51+00:00

This patch adds two new operations for the simple cipher that encrypts or
decrypts a single block at a time.  This will be the main interface after
the existing block operations have moved over to the new block ciphers.

It also adds the crypto_cipher type which is currently only used on the
new operations but will be extended to setkey as well once existing users
have been converted to use block ciphers where applicable.
