This will be used instead of the crypto API one, allowing the crypto API one to be removed. It will also simplify rxkad.c quite a bit. A KUnit test is included. The FCrypt-PCBC test vectors are borrowed from the existing ones in crypto/testmgr.h. Note that this adds the first KUnit test for net/rxrpc/, which previously had no KUnit tests. The FCrypt code is based on crypto/fcrypt.c, but I simplified it a bit. The PCBC part is straightforward and I just wrote it from scratch. Tested with: kunit.py run --kunitconfig net/rxrpc/ Acked-by: David Howells <dhowells@redhat.com> Signed-off-by: Eric Biggers <ebiggers@kernel.org> Tested-by: Marc Dionne <marc.dionne@auristor.com> Link: https://patch.msgid.link/20260522050740.84561-2-ebiggers@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
