Miller" Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org Patch 1/2 takes care of preventing the issue fixed by commit 11789039da53 ("fou: Prevent unbounded recursion in GUE error handler") also with UDP-Lite payloads -- I just realised this might happen from a syzbot report. Patch 2/2 fixes the issue for both UDP and UDP-Lite on IPv6, which I also forgot to deal with in that same commit.
