A while back, I noticed that the crypto and crypto API usage in big_keys were entirely broken in multiple ways, so I rewrote it. Now, I'm rewriting it again, but this time using the simpler ChaCha20Poly1305 library function. This makes the file considerably more simple; the diffstat alone should justify this commit. It also should be faster, since it no longer requires a mutex around the "aead api object" (nor allocations), allowing us to encrypt multiple items in parallel. We also benefit from being able to pass any type of pointer, so we can get rid of the ridiculously complex custom page allocator that big_key really doesn't need. [DH: Change the select CRYPTO_LIB_CHACHA20POLY1305 to a depends on as select doesn't propagate and the build can end up with an =y dependending on some =m pieces. The depends on CRYPTO also had to be removed otherwise the configurator complains about a recursive dependency.] Cc: Andy Lutomirski <luto@kernel.org> Cc: Greg KH <gregkh@linuxfoundation.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: kernel-hardening@lists.openwall.com Reviewed-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Jason A.
