This is a note to let you know that I've just added the patch titled vlan: partially enable SIOCSHWTSTAMP in container to the 5.10-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: vlan-partially-enable-siocshwtstamp-in-container.patch and it can be found in the queue-5.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit c0e4557772e894eb844b9c6520531f16fc227153 Author: Vadim Fedorenko <vadim.fedorenko@xxxxxxxxx> Date: Wed Mar 15 08:33:02 2023 -0700 vlan: partially enable SIOCSHWTSTAMP in container [ Upstream commit 731b73dba359e3ff00517c13aa0daa82b34ff466 ] Setting timestamp filter was explicitly disabled on vlan devices in containers because it might affect other processes on the host. But it's absolutely legit in case when real device is in the same namespace.
