Rather than using the clunky, old, slower wireguard-linux-compat out of tree module, this commit does a patch-by-patch backport of upstream's wireguard to 5.4. This specific backport is in widespread use, being part of SUSE's enterprise kernel, Oracle's enterprise kernel, Google's Android kernel, Gentoo's distro kernel, and probably more I've forgotten about. It's definately the "more proper" way of adding wireguard to a kernel than the ugly compat.h hell of the wireguard-linux-compat repo. And most importantly for OpenWRT, it allows using the same module configuration code for 5.10 as for 5.4, with no need for bifurcation. These patches are from the backport tree which is maintained in the open here: https://git.zx2c4.com/wireguard-linux/log/?h=backport-5.4.y I'll be sending PRs to update this as needed.

Subject: [PATCH] wireguard: selftests: tie socket waiting to target pid
|
|
|
|
commit 88f404a9b1d75388225b1c67b6dd327cb2182777 upstream.
|
|
|
|
Without this, we wind up proceeding too early sometimes when the
|
|
previous process has just used the same listening port. So, we tie the
|
|
listening socket query to the specific pid we're interested in.
