      ORIGINAL SUMMARY: Investigate changes in SERVER-75989: Add support for OpenSSL 3.0 FIPS

      Original Downstream Change Summary

      MongoDB FIPS mode is not supported on MongoDB 6.0.x with OpenSSL 3. This ticket fixes that (when backported). This affects only Ubuntu 22.04, RHEL 9 and Amazon Linux 2023.

      Description of Linked Ticket

      MongoDB does not support OpenSSL 3.0 FIPS due to a breaking API change by OpenSSL in the 3.0 release.

      As per the Open SSL documentation, https://www.openssl.org/docs/man3.0/man7/migration_guide.html -

      Removed FIPS_mode() and FIPS_mode_set()
      These functions are legacy APIs that are not 
      applicable to the new provider model. 
      Applications should instead use 
      EVP_default_properties_is_fips_enabled(3) and 

      This OpenSSL FIPS check in the build system (https://github.com/mongodb/mongo/blob/04e2094cff720a2f75f92f9f95b53422524740c7/src/mongo/util/net/openssl_init.cpp#L149-L165) is conditional on a function that was removed in OpenSSL 3.0

      This was not caught in our existing test cases because we have no test cases that assert that MongoDB OpenSSL FIPS support works on platforms that have OpenSSL FIPS module support.

      We do have a test that ensures log lines match either positive or negative expected values though. The test does not know what log line is expected on which platform though.
