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.

An instruction's QUERY function is executed at initialization, iff the required MSA level is installed. Therefore, it is sufficient to check the bits returned by the QUERY functions. The MSA level does not have to be checked at every function call. crypto/aes/asm/aes-s390x.pl: The AES key schedule must be computed if the required KM or KMC function codes are not available. Formally, the availability of a KMC function code does not imply the availability of the corresponding KM function code. Signed-off-by:

The previous commit removed version negotiation on an HRR. However we should still sanity check the contents of the version field. Reviewed-by:
-
Matt Caswell authored
Previously if a client received an HRR then we would do version negotiation immediately - because we know we are going to get TLSv1.3. However this causes a problem when we emit the 2nd ClientHello because we start changing a whole load of stuff to ommit things that aren't relevant for < TLSv1.3. The spec requires that the 2nd ClientHello is the same except for changes required from the HRR. Therefore the simplest thing to do is to defer the version negotiation until we receive the ServerHello. Fixes #4292 Reviewed-by:

If BN_FLG_STATIC_DATA is set don't cleanse a->d as it will reside in read only memory. If BN_FLG_MALLOCED is not set don't modify the BIGNUM at all. This change applies to BN_clear_free() and BN_free(). Now the BIGNUM structure is opaque applications cannot create a BIGNUM structure without BN_FLG_MALLOCED being set so they are unaffected. Update internal DH routines so they only copy pointers for read only parameters. Reviewed-by:
