[License Exception Request] Connect: allow OpenSSL license for swift-nio-ssl #823

Open akshayjshah opened 6 days ago

akshayjshah commented 6 days ago

Component details

The component is swift-nio-ssl, part of Swift's non-blocking networking stack, at the most recent version. (All versions I checked have the same problem, but let's focus on the latest version.)

The repository is https://github.com/apple/swift-nio-ssl. The repository as a whole claims to be available under an Apache 2 license, but it includes code that's licensed under the OpenSSL license. The text in that file also allows use under the CRYPTOGAMS license or GPL v2.

Any alternatives?

As far as I know, swift-nio-ssl is the only way to use HTTP/2 + TLS and have access to HTTP trailers on iOS.

Integrates with other components?

connect-swift is an RPC library that's part of the broader Connect project, which recently joined the CNCF Sandbox. swift-nio-ssl is a build-time dependency of the connect-swift subpackage that offers gRPC compatibility.

For context, swift-nio-ssl is also used in gRPC's Swift implementation: https://github.com/grpc/grpc-swift/blob/main/Package.swift#L81.
