From c38c5cfd3ed7c59fc03134f6a3e53ed440922fdc Mon Sep 17 00:00:00 2001 From: Thomas Lange Date: Thu, 4 Jan 2024 09:57:44 +0100 Subject: [PATCH] net: Implement missing SO_TIMESTAMPING_NEW cmsg support [ Upstream commit 382a32018b74f407008615e0e831d05ed28e81cd ] Commit 9718475e6908 ("socket: Add SO_TIMESTAMPING_NEW") added the new socket option SO_TIMESTAMPING_NEW. However, it was never implemented in __sock_cmsg_send thus breaking SO_TIMESTAMPING cmsg for platforms using SO_TIMESTAMPING_NEW.
