The crypto app in OTP can now be compiled, linked and used with the new OpenSSL 3.0 cryptolib.
It has not yet been extensively tested and is in this release *not recommended* for other usages than experiments and alpha testing. There are not yet any guaranties that it works, not even together with other OTP applications like for example SSL and SSH, although there are no known errors.
Compiling and linking with OpenSSL 3.0 cryptolib in compatibility modes (for example to behave as 1.1.1) are not tested. It is not tested with external providers.
The support for FIPS mode does not yet work, and is disabled when compiled with OpenSSL 3.0.
Deprecated functions in the OpenSSL 3.0 cryptolib must not be disabled as OTP/crypto still uses some of the deprecated API functions. The gcc flag -Wno-deprecated-declarations is set to prevent deprecation warnings to be printed when compiling.
The hash algorithms md4 and ripemd160 are disabled temporarily when compiled with OpenSSL 3.0.
The ciphers blowfish_cbc, blowfish_cfb64, blowfish_ecb, blowfish_ofb64, des_cbc, des_cfb, des_ecb, rc2_cbc and rc4 are disabled temporarily when compiled with OpenSSL 3.0.

Responsiveness of processes executing on normal or low priority could suffer due to code purging or literal area removal on systems with a huge amount of processes. This since during these operations all processes on the system were scheduled for execution at once.
This problem has been fixed by introducing a limit on outstanding purge and copy literal requests in the system. By default this limit is set to twice the amount of schedulers on the system. This will ensure that schedulers will have enough work scheduled to perform these operations as quickly as possible at the same time as other work will be interleaved to a much higher degree. Performance of these operations will however be somewhat degraded due to the overhead of enforcing this limit compared to when using a very large limit.
This limit can be set by passing the +zosrl command line argument to erl, or by calling erlang:system_flag(outstanding_system_requests_limit, NewLimit).

The compiler would replace known failing calls (such as atom_to_list(42)) with a call to error(badarg). With the extended error information introduced in OTP 24 (EEP 54), those "optimized" calls would not have extended error information. To ensure that as much extended error information as possible is available, the compiler now keeps the original call even when it is known to fail.

In epmd_ntop, the #if defined(EPMD6) conditional was inverted and it was only including the IPv6-specific code when EPMD6 was undefined. This was causing IPv6 addrs to be interpreted as IPv4 addrs and generating nonsense IPv4 addresses as output.
Several places were incorrectly using 'num_sockets' instead of 'i' to index into the iserv_addr array during error logging. This would result in a read into uninitialized data in the iserv_addr array.
