[PATCH 0/5] ML-KEM and X-Wing support

[Eric Biggers <ebiggers@kernel.org>]

This series applies to v7.1-rc5.  It is a proof-of-concept that won't be
merged until there is an in-kernel user.  Multiple people have been
asking about this though, so I wanted to get ahead of the curve and
provide something that people can experiment with if needed.

This series adds support for "post-quantum" (i.e. quantum-resistant) key
encapsulation to the kernel's crypto library.  Specifically this
includes ML-KEM-768 and ML-KEM-1024, and the X-Wing hybrid KEM built on
top of it.  The ML-KEM functions are put in the CRYPTO_INTERNAL
namespace, as they will be used only as a component of hybrid KEMs.

It's likely this will eventually be useful for at least one of the
in-kernel users of classical key agreement schemes (currently NVMe
authentication, Bluetooth, and WireGuard).  However, the details of the
upgrade to "post-quantum" will be up to the protocol authors in each
case.  I suggest that X-Wing be chosen when possible.
