kernel: 5.4: import wireguard backport
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.

commit 84faa307249b341f6ad8de3e1869d77a65e26669 upstream.
|
|
|
|
|
|
|
|

|
Somehow this was forgotten when Zinc was being split into oddly shaped
|
|
|
|
|
pieces, resulting in linker errors. The x86_64 glue has a specific key
|
|
|
|
|
generation implementation, but the Arm one does not. However, it can
|
|
|
|
|
still receive the NEON speedups by calling the ordinary DH function
|
|
|
|
|
using the base point.
