[gnutls-devel] GnuTLS | DRBG: Remove all traces of FIPS 140-2 continuous self test (!820)

[Development of GNU's TLS library]

Dmitry Eremin-Solenikov commented on a discussion on lib/nettle/int/drbg-aes.c:

>  		memset(seed, 0, DRBG_AES_SEED_SIZE);

>  
> -	/* Throw the first block generated. FIPS 140-2 requirement (see

> -	 */
> -	if (ctx->prev_block_present == 0) {
> -		INCREMENT(sizeof(ctx->v), ctx->v);
> -		aes256_encrypt(&ctx->key, AES_BLOCK_SIZE, ctx->prev_block, ctx->v);
> -
> -		ctx->prev_block_present = 1;
> -	}
> -

I did not yet have time to cross-check FIPS 140-2 and SP 800-90A that we are allowed not to drop first block.
