@enj enj commented Nov 2, 2021

This change updates the makeClientHello logic to only advertise TLS
1.3 ciphers when tls.Config.MinVersion is set to tls.VersionTLS13
(i.e the client only supports TLS 1.3). Previously, TLS 1.2 ciphers
would be included in the client hello message.

Fixes #57771

Message from Go Bot:

Patch Set 1:

Congratulations on opening your first change. Thank you for your contribution!

Next steps:
A maintainer will review your change and provide feedback. See
https://golang.org/doc/contribute.html#review for more info and tips to get your
patch through code review.

Most changes in the Go project go through a few rounds of revision. This can be
surprising to people new to the project. The careful, iterative review process
is our way of helping mentor contributors and ensuring that their contributions
have a lasting impact.

During May-July and Nov-Jan the Go project is in a code freeze, during which
little code gets reviewed or merged. If a reviewer responds with a comment like
R=go1.11 or adds a tag like "wait-release", it means that this CL will be
reviewed as part of the next development cycle. See https://golang.org/s/release
for more details.
