Explicitly load both the "default" and "legacy" providers in the test case. The "legacy" provider is intended to be used with the "default" provider. The "default" provider is typically loaded automatically, but that only happens when no other provider has been loaded yet.
Check for the function we actually use. Both SSL_set0_tmp_dh_pkey() and SSL_CTX_set0_tmp_dh_pkey() were added in OpenSSL 3.0.
Enable automatic DH parameters for TLS 1.2 or earlier when neither SSLSocket#tmp_dh nor SSLSocket#tmp_dh_callback is set. This is supported since OpenSSL 1.1.0. This allows us to remove the default tmp_dh_callback proc defined in lib/openssl/ssl.rb, which uses hard-coded parameters and is not Ractor-shareable.
tmp_dh_callback no longer has a default value. It also no longer has to share code with tmp_ecdh_callback, which was removed in v3.0.0.

I don't think the failure with openssl-master with the fips provider is relevant, but I haven't been able to reproduce it locally. |

I executed the current latest master branch dfbbac6 with the latest OpenSSL master branch openssl/openssl@b20da23. I can see the failure below. https://github.com/junaruga/ruby-openssl/actions/runs/16680199093/job/47216748820 |

I opened the issue ticket #926 for the FIPS test failures. |

SSLSocket#tmp_dhnorSSLSocket#tmp_dh_callbackis set. This is supported since OpenSSL 1.1.0.This allows us to remove the default
tmp_dh_callbackproc defined inlib/openssl/ssl.rb, which uses hard-coded parameters and is not Ractor-shareable.Also, a few cleanups in related code:
provider: load "default" provider in test_openssl_legacy_provider
Explicitly load both the "default" and "legacy" providers in the test case.
The "legacy" provider is intended to be used with the "default" provider. The "default" provider is typically loaded automatically, but that only happens when no other provider has been loaded yet.
ssl: fix extconf.rb check for SSL_CTX_set0_tmp_dh_pkey()
Check for the function we actually use. Both SSL_set0_tmp_dh_pkey() and SSL_CTX_set0_tmp_dh_pkey() were added in OpenSSL 3.0.
ssl: refactor tmp_dh_callback handling
tmp_dh_callback no longer has a default value. It also no longer has to share code with tmp_ecdh_callback, which was removed in v3.0.0.
