   Dear Maintainer,   
      
   I've updated to the latest version of the 6.12. branch from 6.12.63 to   
   6.12.69.   
      
   I have a ip6gre tunnel secured by ipsec. after the update to that   
   version no packet is received anymore on the gre device and the error   
   counter counts up for every inbound gre packet.   
      
   The information that the error counter counts seems to confirm that the   
   kernel finds the right gre device the packet should be delivered to.   
      
   I recompiled the kernel reverting   
   https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git   
   commit/net/ipv6/ip6_tunnel.c?id=81c734dae203757fb3c9eee6f9896386940776bd   
      
   and now the custom dpkg-buildpackage (now obviosly -unsigned) works   
   again.   
      
   Looking at the code I don't see why it would fail, especially since   
   kernel 6.19 from ubuntu seems to work (I did not check if 6.19 includes   
   this, if it does not that the mentioned commit above is the real   
   regression)   
      
   Thanks
