CC| |kp@freebsd.org --- Comment #12 from Bjoern A. Zeeb --- (In reply to Robin Haberkorn from comment #11) Yes I understand why the question was for the original one; I just wanted = to understand as the "copy" should have it too then and when manually going up= the stack I couldn't spot where it might be cleared. I wonder what Dan Epure's report looked like, Glebius? Do you have a backt= race from that? Same code paths? Also UDP? Also ovpn loaded? I don't know how the openvpn kernel module is hooking into the input path; = if it's using u_tun_func then that at least would explain why we do not see it= in the backtrace. And then Takahiro Kurosawa's analysis from #c7 sounds fairly valid if m_unshare can lose the PKTHDR on the copy. OpenVPN doesn't have t= o be active; it seems if there's an interface the filtering function will be ho= oked up. And then it's not a regression in iwm or the network stack; then it's imply the feature.
