DRBG CAVS test error

[Bhat, Jayalakshmi Manjunath]

Hi All

I am executing DRBG CAVS test, using drbg_nopr_hmac_sha512. Below is the code 
snippet.

test_data.testentropy = &testentropy;
drbg_string_fill(&testentropy, drbg_st->entropy_nonce_input, 
drbg_st->entropy_nonce_len);
drbg_string_fill(&pers, drbg_st->personalization_string, 
iv_struct->personalization_string_len);
ret = crypto_drbg_reset_test(drng, &pers, &test_data);

drbg_string_fill(&additional_input, drbg_st->additional_input_reseed, 
drbg_st->additional_input_reseed_len);
if (drbg_st->entropy_input_reseed_len >0)
        drbg_string_fill(&entropy_input, drbg_st->>entropy_input_reseed, 
drbg_st->entropy_input_reseed_len);
ret = crypto_drbg_get_bytes_addtl(drng, buf, test->expectedlen, 
&additional_input);

drbg_string_fill(&additional_input,   drbg_st->additional_generate,    
drbg_st->additional_generate_len);
if (drbg_st->entropy_input_generate_len >0)
        drbg_string_fill(&entropy_input, drbg_st->entropy_input_generate, 
drbg_st->entropy_input_generate_len);
ret = crypto_drbg_get_bytes_addtl(drng, buf, test->expectedlen, 
&additional_input);

drbg_string_fill(&additional_input, drbg_st->additional_input_final,    
drbg_st->additional_input_final_len);
if (additional_input_final_len > 0)
        drbg_string_fill(&entropy_input, drbg_st->entropy_input_final, 
drbg_st->entropy_input_final_len);
ret = crypto_drbg_get_bytes_addtl(drng, buf, test->expectedlen, 
&additional_input);

However the output generated seems to be wrong. Can any help me to indicate 
what I am doing wrong

Regards,
Jaya
