The function BN_security_bits() uses the values from SP800-57 to assign security bit values for different FF key sizes. However the value for 192 security bits is wrong. SP800-57 has it as 7680 but the code had it as 7690. Reviewed-by:

Add a check for NULL return in t1_lib.c. Since return type of ssl_cert_lookup_by_idx is pointer and unify coding style, I changed from zero to NULL in ssl_cert.c. Remove unnecessary space for ++. Fix incorrect condition Expression is always false because 'else if' condition matches previous condition. SInce the next line of 'else if' condition has substituted TLSEXT_ECPOINTFORMAT_ansiX962_compressed_char2, the 'else if' condition should compare with NID_X9_62_characteristic_two_field. Reviewed-by:

The drbg's lock must be held across calls to RAND_DRBG_generate() to prevent simultaneous modification of internal state. This was observed in practice with simultaneous SSL_new() calls attempting to seed the (separate) per-SSL RAND_DRBG instances from the global rand_drbg instance; this eventually led to simultaneous calls to ctr_BCC_update() attempting to increment drbg->bltmp_pos for their respective partial final block, violating the invariant that bltmp_pos < 16. The AES operations performed in ctr_BCC_blocks() makes the race window quite easy to trigger. A value of bltmp_pos greater than 16 induces catastrophic failure in ctr_BCC_final(), with subtraction overflowing and leading to an attempt to memset() to zero a very large range, which eventually reaches an unmapped page and segfaults. Provide the needed locking in get_entropy_from_parent(), as well as fixing a similar issue in RAND_priv_bytes(). There is also an unlocked call to RAND_DRBG_generate() in ssl_randbytes(), but the requisite serialization is already guaranteed by the requirements on the application's usage of SSL objects, and no further locking is needed for correct behavior. In that case, leave a comment noting the apparent discrepancy and the reason for its safety (at present). Reviewed-by:

The DRBG_RESEED state plays an analogue role to the |reseed_required_flag| in Appendix B.3.4 of [NIST SP 800-90A Rev. 1]. The latter is a local variable, the scope of which is limited to the RAND_DRBG_generate() function. Hence there is no need for a DRBG_RESEED state outside of the generate function. This state was removed and replaced by a local variable |reseed_required|. Reviewed-by:

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:

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:
