Now I’m getting 0x300 in skb->protocol for what tcpdump -X makes me believe is a fragmented IP packet.
I also get it for unfragmented packets, and the kernel source does not ever set it, which got me on the right track for searching. Turns out that the buster-backports kernel has the fix already: https://lore.kernel.org/netdev/20190318053952.115180-1-komachi.yoshiki@lab.ntt.co.jp/t/ (local) describes my problem, and booting into 5.10 instead of 4.19 gives me the correct skb->protocol value. bye, //mirabilos -- Infrastrukturexperte • tarent solutions GmbH Am Dickobskreuz 10, D-53121 Bonn • http://www.tarent.de/ Telephon +49 228 54881-393 • Fax: +49 228 54881-235 HRB AG Bonn 5168 • USt-ID (VAT): DE122264941 Geschäftsführer: Dr. Stefan Barth, Kai Ebenrett, Boris Esser, Alexander Steeg **************************************************** /⁀\ The UTF-8 Ribbon ╲ ╱ Campaign against Mit dem tarent-Newsletter nichts mehr verpassen: ╳ HTML eMail!
