OpenSSL 3.0 transition might lead to unsupported protocols

[Simon Chopin]

OpenSSL 3.0, which is planned to land in the archive Very Soon™, has moved quite a few algorithms to its "legacy" provider, which isn't loaded by default. Some of those algorithms are used in various protocols implemented by wpa_supplicant, so it's likely that the package will be broken in this regard.

Sadly, this isn't caught by either the build-time tests nor the autopkgtests.

A first good step would be to patch wpa_supplicant to load the "legacy" provider (and the default one too, cf https://www.openssl.org/docs/manmaster/man7/crypto.html , look for "legacy").

Upstream fixed it in https://w1.fi/cgit/hostap/commit/?id=ff2eccbd which is included in the new 2.10 version uploaded to Ubuntu
