Hi, Ubuntu kernel 5.3.0-52.46 breaks the DKMS build for wireguard-linux-compat 1.0.20200429. Function skb_reset_redirect() got added to the kernel's include/linux/skbuff.h, but collides with the function defintion from wireguard-linux-compat's compat/compat.h: https://kernel.ubuntu.com/git/ubuntu/ubuntu-eoan.git/commit/include/linux/skbuff.h?h=Ubuntu-5.3.0-52.46&id=b8845f9376917c49f5e219288613c6cbe172f884 Kernel 5.3.0-52.46 is not only used for Ubuntu 19.10, but serves also as HWE kernel in Ubuntu 18.04. I've got the DKMS module to compile again on Ubuntu 18.04 using the attached patch, but I'm not sure it that's the correct solution to the problem since the colliding function definitions differ and I'm not really familiar with the kernel's network internals. Regards Pascal
