gtp-link: set IPv6 socket only GTP driver bails out for IPv4-mapped-IPv6 socket with EADDRNOAVAIL, to prevent issues with setsockopt IPV6_ADDRFORM. GTP control plane checks that tunnel family matches the socket family for this GTP device, ie. there is a 1:1 mapping between the socket listener and the device which determines the supported IP tunnel header.

In order to control the kernel-side GTP-U plane, a netlink based control interface between GTP-C in userspace and GTP-U in kernelspace was invented.
The encoding and decoding of these control messages is implemented in the libgtpnl (library for GTP netlink).
libgtpnl is part of the Osmocom Open Source Mobile Communications project.
The official homepage of the project is https://osmocom.org/projects/linux-kernel-gtp-u/wiki/Libgtpnl
You can clone from the official libgtpnl.git repository using
git clone https://gitea.osmocom.org/cellular-infrastructure/libgtpnl
