The one creating the DRBG should instantiate it, it's there that we know which parameters we should use to instantiate it. This splits the rand init in two parts to avoid a deadlock because when the global drbg is created it wands to call rand_add on the global rand method.

The DRBG callbacks 'get_entropy()' and 'cleanup_entropy()' are designed in such a way that the randomness buffer does not have to be allocated by the calling function. It receives the address of a dynamically allocated buffer from get_entropy() and returns this address to cleanup_entropy(), where it is freed. If these two calls are properly paired, the address can be stored in a stack local variable of the calling function, so there is no need for having a 'randomness' member (and a 'filled' member) in 'RAND_DRBG'.

Unlike the NIST DRBG standard, entropy counts are in bits and buffer lengths are in bytes. This has lead to some confusion and errors in the past, see my comment on PR 3789. To clarify the destinction between entropy counts and buffer lengths, a 'len' suffix has been added to all member names of RAND_DRBG which represent buffer lengths: - {min,max}_{entropy,adin,nonce,pers} + {min,max}_{entropy,adin,nonce,pers}len This change makes naming also more consistent, as can be seen in the diffs, for example: - else if (adinlen > drbg->max_adin) { + else if (adinlen > drbg->max_adinlen) { Also replaced all 'ent's by 'entropy's, following a suggestion of Paul Dale.

Add a new global DRBG for private keys used by RAND_priv_bytes. Add BN_priv_rand() and BN_priv_rand_range() which use RAND_priv_bytes(). Change callers to use the appropriate BN_priv... function.

Give each SSL object it's own DRBG, chained to the parent global DRBG which is used only as a source of randomness into the per-SSL DRBG. This is used for all session, ticket, and pre-master secret keys. It is NOT used for ECDH key generation which use only the global DRBG. (Doing that without changing the API is tricky, if not impossible.) Reviewed-by: NPaul Dale <paul.dale@oracle.com> (Merged from https://github.com/openssl/openssl/pull/4050)

If RAND_add wraps around, XOR with existing. Add test to drbgtest that does the wrap-around. Re-order seeding and stop after first success. Add RAND_poll_ex() Use the DF and therefore lower RANDOMNESS_NEEDED. Also, for child DRBG's, mix in the address as the personalization bits. Centralize the entropy callbacks, from drbg_lib to rand_lib. (Conceptually, entropy is part of the enclosing application.) Thanks to Dr. Matthias St Pierre for the suggestion. Various code cleanups: -Make state an enum; inline RANDerr calls. -Add RAND_POLL_RETRIES (thanks Pauli for the idea) -Remove most RAND_seed calls from rest of library -Rename DRBG_CTX to RAND_DRBG, etc. -Move some code from drbg_lib to drbg_rand; drbg_lib is now only the implementation of NIST DRBG. -Remove blocklength Reviewed-by: NPaul Dale <paul.dale@oracle.com> (Merged from https://github.com/openssl/openssl/pull/4019)
