Make all configuration macros available for application by making sure they are available in opensslconf.h, by giving them names starting with "OPENSSL_" to avoid conflicts with other packages and by making sure e_os2.h will cover all platform-specific cases together with opensslconf.h. I've checked fairly well that nothing breaks with this (apart from external software that will adapt if they have used something like NO_KRB5), but I can't guarantee it completely, so a review of this change would be a good thing.

DRBG: add locking api This commit adds three new accessors to the internal DRBG lock int RAND_DRBG_lock(RAND_DRBG *drbg) int RAND_DRBG_unlock(RAND_DRBG *drbg) int RAND_DRBG_enable_locking(RAND_DRBG *drbg) The three shared DRBGs are intended to be used concurrently, so they have locking enabled by default. It is the callers responsibility to guard access to the shared DRBGs by calls to RAND_DRBG_lock() and RAND_DRBG_unlock(). All other DRBG instances don't have locking enabled by default, because they are intendended to be used by a single thread. If it is desired, locking can be enabled by using RAND_DRBG_enable_locking(). Reviewed-by: Rich Salz <rsalz@openssl.org> (Merged from https://github.com/openssl/openssl/pull/5294)

(This header contains functions which are internal, but shared between libcrypto and libssl.)

crypto/rand: restore the generic DRBG implementation The DRGB concept described in NIST SP 800-90A provides for having different algorithms to generate random output. In fact, the FIPS object module used to implement three of them, CTR DRBG, HASH DRBG and HMAC DRBG. When the FIPS code was ported to master in #4019, two of the three algorithms were dropped, and together with those the entire code that made RAND_DRBG generic was removed, since only one concrete implementation was left. This commit restores the original generic implementation of the DRBG, making it possible again to add additional implementations using different algorithms (like RAND_DRBG_CHACHA20) in the future.

DRBG: fix reseeding via RAND_add()/RAND_seed() with large input In pull request #4328 the seeding of the DRBG via RAND_add()/RAND_seed() was implemented by buffering the data in a random pool where it is picked up later by the rand_drbg_get_entropy() callback. This buffer was limited to the size of 4096 bytes. When a larger input was added via RAND_add() or RAND_seed() to the DRBG, the reseeding failed, but the error returned by the DRBG was ignored by the two calling functions, which both don't return an error code. As a consequence, the data provided by the application was effectively ignored. This commit fixes the problem by a more efficient implementation which does not copy the data in memory and by raising the buffer the size limit to INT32_MAX (2 gigabytes). This is less than the NIST limit of 2^35 bits but it was chosen intentionally to avoid platform dependent problems like integer sizes and/or signed/unsigned conversion. Additionally, the DRBG is now less permissive on errors: In addition to pushing a message to the openssl error stack, it enters the error state, which forces a reinstantiation on next call. Thanks go to Dr. Falko Strenzke for reporting this issue to the openssl-security mailing list. After internal discussion the issue has been categorized as not being security relevant, because the DRBG reseeds automatically and is fully functional even without additional randomness provided by the application.

DRBG: add locking api This commit adds three new accessors to the internal DRBG lock int RAND_DRBG_lock(RAND_DRBG *drbg) int RAND_DRBG_unlock(RAND_DRBG *drbg) int RAND_DRBG_enable_locking(RAND_DRBG *drbg) The three shared DRBGs are intended to be used concurrently, so they have locking enabled by default. It is the callers responsibility to guard access to the shared DRBGs by calls to RAND_DRBG_lock() and RAND_DRBG_unlock(). All other DRBG instances don't have locking enabled by default, because they are intendended to be used by a single thread. If it is desired, locking can be enabled by using RAND_DRBG_enable_locking(). Reviewed-by: Rich Salz <rsalz@openssl.org> (Merged from https://github.com/openssl/openssl/pull/5294)

Fix reseeding issues of the public RAND_DRBG Reseeding is handled very differently by the classic RAND_METHOD API and the new RAND_DRBG api. These differences led to some problems when the new RAND_DRBG was made the default OpenSSL RNG. In particular, RAND_add() did not work as expected anymore. These issues are discussed on the thread '[openssl-dev] Plea for a new public OpenSSL RNG API' and in Pull Request #4328. This commit fixes the mentioned issues, introducing the following changes: - Replace the fixed size RAND_BYTES_BUFFER by a new RAND_POOL API which facilitates collecting entropy by the get_entropy() callback. - Don't use RAND_poll()/RAND_add() for collecting entropy from the get_entropy() callback anymore. Instead, replace RAND_poll() by RAND_POOL_acquire_entropy(). - Add a new function rand_drbg_restart() which tries to get the DRBG in an instantiated state by all means, regardless of the current state (uninstantiated, error, ...) the DRBG is in. If the caller provides entropy or additional input, it will be used for reseeding. - Restore the original documented behaviour of RAND_add() and RAND_poll() (namely to reseed the DRBG immediately) by a new implementation based on rand_drbg_restart(). - Add automatic error recovery from temporary failures of the entropy source to RAND_DRBG_generate() using the rand_drbg_restart() function.

crypto/rand: restore the generic DRBG implementation The DRGB concept described in NIST SP 800-90A provides for having different algorithms to generate random output. In fact, the FIPS object module used to implement three of them, CTR DRBG, HASH DRBG and HMAC DRBG. When the FIPS code was ported to master in #4019, two of the three algorithms were dropped, and together with those the entire code that made RAND_DRBG generic was removed, since only one concrete implementation was left. This commit restores the original generic implementation of the DRBG, making it possible again to add additional implementations using different algorithms (like RAND_DRBG_CHACHA20) in the future.
