From 0257427146e84af365612508ace9d0d87dfb7d7a Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Thu, 27 Jul 2023 13:35:50 -0400 Subject: [PATCH] net/tls: Add TLS Alert definitions I'm about to add support for kernel handshake API consumers to send TLS Alerts, so introduce the needed protocol definitions in the new header tls_prot.h. This presages support for Closure alerts. Also, support for alerts is a pre-requite for handling session re-keying, where one peer will signal the need for a re-key by sending a TLS Alert.
