[PATCH] crypto: add alignment handling to digest layer
anemo at mba

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.

Ping. This patch can be applied cleanly to 2.6.17-rc1.

should pass properly aligned buffer to update()/final() method. This
patch also add cra_alignmask to some hash modules.

This patch is in my queue. I'll be travelling for the next couple of
weeks but I'll get onto it after that.

Thanks,

Don't we need to copy this to an aligned buffer?

We don't. I think update functions do not need an aligned buffer for
data which is smaller then the alignment size.

You're right. If we do ever get any hardware that requires this we can
always change it later on.

Another thing, could you pleas change the stack allocation in final so
that it does it like cbc_process_decrypt? The reason is that gcc is too
stupid to not allocate that buffer unconditionally.

Thanks,

I can do it, but it will add another overhead. (we must call
crypto_tfm_alg_digestsize() unconditionally)

It seems modern gcc (at least gcc 3.4 on i386 and mips) can allocate
the buffer conditionally. It is better to optimize for newer gcc,
isn't it?

Of course it does. I must've been confused.
