From c669d837f4dec1d158af45e6c327fecc6461f7ed Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Wed, 24 Nov 2021 15:25:57 -0800 Subject: [PATCH] selftests: tls: test for correct proto_ops Previous patch fixes overriding callbacks incorrectly. Triggering the crash in sendpage_locked would be more spectacular but it's hard to get to, so take the easier path of proving this is broken and call getname. We're currently getting IPv4 socket info on an IPv6 socket.
