From 73f88915a119eb9c323caf1537b3291129858930 Mon Sep 17 00:00:00 2001 From: Kyle Evans Date: Sun, 20 Apr 2025 22:08:17 -0500 Subject: [PATCH] wireguard-tools: ipc: freebsd: use AF_LOCAL for the control socket AF_INET assumes that IPv4 is built into the kernel, but it's completely valid to build a kernel without it. unix(4) sockets, on the other hand, are not-optional in the kernel build. Given that interface ioctls can be invoked on any kind of socket, switch to the safer one to avoid breaking on IPv6-only kernels.
