vsftpd/0021-Follow-crypto-policies-for-ssl-ciphers.patch
Pavol Žáčik ca207c8895
Adjust opinionated use of cryptography
Adhere to crypto-policies when restricting
TLS 1.3 ciphersuites by default.

When using DH, let OpenSSL set up its params
automatically by default.

When using ephemeral ECDH, allow all supported
curves. Deprecate the `ecdh_param_file` config
option which is broken since the transition to
OpenSSL 3.0.

Also remove old unused patches.
