ccm128.c: initialize ctx->block (what I was smoking?).

/* First you setup M and L parameters and pass the key schedule */

void CRYPTO_ccm128_init(CCM128_CONTEXT *ctx,

	unsigned int M,unsigned int L,void *key)

	unsigned int M,unsigned int L,void *key,block128_f block)

{

	memset(ctx->nonce.c,0,sizeof(ctx->nonce.c));

	ctx->nonce.c[0] = ((u8)(L-1)&7) | (u8)(((M-2)/2)&7)<<3;

	ctx->blocks = 0;

	ctx->block = block;

	ctx->key = key;

}
