The branch main has been updated by jhb: URL: https://cgit.FreeBSD.org/src/commit/?id=6372fd253e3266c6eb271f49159f1632d527c9bd commit 6372fd253e3266c6eb271f49159f1632d527c9bd Author: John Baldwin <jhb@FreeBSD.org> AuthorDate: 2021-08-17 21:40:16 +0000 Commit: John Baldwin <jhb@FreeBSD.org> CommitDate: 2021-08-17 21:41:42 +0000 OpenSSL: Add support for Chacha20-Poly1305 to kernel TLS on FreeBSD. FreeBSD's kernel TLS supports Chacha20 for both TLS 1.2 and TLS 1.3. NB: This commit has not yet been merged upstream as it is deemed a new feature and did not make the feature freeze cutoff for OpenSSL 3.0.
