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] crypto: x86/poly1305 - emit does base conversion itself
|
|
|
|
commit f9e7fe32a792726186301423ff63a465d63386e1 upstream.
|
|
|
|
The emit code does optional base conversion itself in assembly, so we
|
|
don't need to do that here. Also, neither one of these functions uses
|
|
simd instructions, so checking for that doesn't make sense either.
