From: Thomas Lange <thomas@corelatus.se> stable inclusion from stable-v6.6.11 commit 200bc36613253fe1feb61edd43dcd0e496fdb2e0 bugzilla: https://gitee.com/openeuler/kernel/issues/I99TJK Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ 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.
