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/chacha - only unregister algorithms if registered
|
|
|
|
commit b62755aed3a3f5ca9edd2718339ccea3b6bbbe57 upstream.
|
|
|
|
It's not valid to call crypto_unregister_skciphers() without a prior
|
|
call to crypto_register_skciphers().

|
|

Fixes: 84e03fa39fbe ("crypto: x86/chacha - expose SIMD ChaCha routine as library function")
