Description

In development of https://github.com/openssl/openssl/pull/2341 I noticed that I can never seem to get picotls to resume if it sends a HelloRetryRequest during the resuming handshake. Is this a known restriction or a bug (possibly mine)?

Contributor guide

Research direction

Start by reproducing a resumption handshake in picotls that receives a HelloRetryRequest, using the OpenSSL PR 2341 context described in the issue. Compare the behavior with the RFC8446 resumption flow and determine whether this is an intentional restriction or a bug; done means the behavior is documented or corrected and verified with a regression test.
