[CRYPTO] sha: Add module aliases for sha1 / sha256

2006-09-21T01:40:20+00:00

Crypto modules should be loadable by their .cra_driver_name, so
we should make MODULE_ALIAS()es with these names. This patch adds
aliases for SHA1 and SHA256 only as that's what we need for
PadLock-SHA driver.

[CRYPTO] all: Pass tfm instead of ctx to algorithms

2006-06-26T07:34:39+00:00

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.

[CRYPTO] digest: Add alignment handling

2006-06-26T07:34:38+00:00

Some hash modules load/store data words directly.  The digest layer
should pass properly aligned buffer to update()/final() method.  This
patch also add cra_alignmask to some hash modules.

[CRYPTO] sha1: Fixed off-by-64 bug in sha1_update

2006-01-09T22:15:56+00:00

After a partial update, the done pointer is off to the right by 64 bytes.

[CRYPTO] sha1: Avoid shifting count left and right

2006-01-09T22:15:46+00:00

This patch avoids shifting the count left and right needlessly for each
call to sha1_update().  It instead can be done only once at the end in
sha1_final().

Keeping the previous test example (sha1_update() successively called with
len=64), a 1.3% performance increase can be observed on i386, or 0.2% on
ARM.  The generated code is also smaller on ARM.

[CRYPTO] sha1: Rename i/j to done/partial

2006-01-09T22:15:44+00:00

This patch gives more descriptive names to the variables i and j.

[CRYPTO] sha1: Avoid useless memcpy()

2006-01-09T22:15:41+00:00

The current code unconditionally copy the first block for every call to
sha1_update().  This can be avoided if there is no pending partial block.
This is always the case on the first call to sha1_update() (if the length
is >= 64 of course.

Furthermore, temp does need to be called if sha_transform is never invoked.
Also consolidate the sha_transform calls into one to reduce code size.

[CRYPTO] Use standard byte order macros wherever possible

2006-01-09T22:15:34+00:00

A lot of crypto code needs to read/write a 32-bit/64-bit words in a
specific gender.  Many of them open code them by reading/writing one
byte at a time.  This patch converts all the applicable usages over
to use the standard byte order macros.

This is based on a previous patch by Denis Vlasenko.

Linux-2.6.12-rc2

2005-04-16T22:20:36+00:00

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
