[CRYPTO] aes: Fixed array boundary violation

2006-03-21T09:14:10+00:00

The AES setkey routine writes 64 bytes to the E_KEY area even though
there are only 60 bytes there.  It is in fact safe since E_KEY is
immediately follwed by D_KEY which is initialised afterwards.  However,
doing this may trigger undefined behaviour and makes Coverity unhappy.

So by combining E_KEY and D_KEY into one array we sidestep this issue
altogether.

This problem was reported by Adrian Bunk.

[CRYPTO] tcrypt: Fix key alignment

2006-03-21T09:14:09+00:00

Force 32-bit alignment on keys in tcrypt test vectors.  Also rearrange the
structure to prevent unnecessary padding.

[CRYPTO] api: Align tfm context as wide as possible

2006-03-21T09:14:08+00:00

Since tfm contexts can contain arbitrary types we should provide at least
natural alignment (__attribute__ ((__aligned__))) for them.  In particular,
this is needed on the Xscale which is a 32-bit architecture with a u64 type
that requires 64-bit alignment.  This problem was reported by Ronen Shitrit.

The crypto_tfm structure's size was 44 bytes on 32-bit architectures and
80 bytes on 64-bit architectures.  So adding this requirement only means
that we have to add an extra 4 bytes on 32-bit architectures.

On i386 the natural alignment is 16 bytes which also benefits the VIA
Padlock as it no longer has to manually align its context structure to
128 bits.

[PATCH] remove bogus asm/bug.h includes.

2006-02-08T01:56:35+00:00

A bunch of asm/bug.h includes are both not needed (since it will get
pulled anyway) and bogus (since they are done too early).  Removed.

[CRYPTO] cipher: Set alignmask for multi-byte loads

2006-01-09T22:16:00+00:00

Many cipher implementations use 4-byte/8-byte loads/stores which require
alignment on some architectures.  This patch explicitly sets the alignment
requirements for them.

[CRYPTO] api: Require block size to be less than PAGE_SIZE/8

2006-01-09T22:15:58+00:00

The cipher code path may allocate up to two blocks of data on the stack.
Therefore we need to place limits on the maximum block size.
