Add basic arm64 support into OpenSSL

[Wookey]

Openssl doesn't build for arm without having a suitable config line in its ./configure.

This patch adds one, with assembler turned off, which allows the package to build.

The patch is probably broken.

it should have SIXTY_FOUR_BIT instead of BN_LLONG

[Riku Voipio (riku-voipio)]

Updated patch - now with 64bit pointers.

Just checked - OE has same line - since October.

[Ard Biesheuvel (ard-biesheuvel)]

In fact, this still does not look correct: it should read SIXTY_FOUR_BIT_LONG not SIXTY_FOUR_BIT (the latter is intended for Win64 style LLP64 model)

Hi Ard,

Thanks, good catch - apparently we have the correct item OpenEmbedded but the Ubuntu patch has wrong one. Not sure how it ended up there. Updated patched attached.

We would still need someone to write the assembler code to take advantage of the ARMv8 AES and SHA instructions.

[Ard Biesheuvel (ard-biesheuvel)]

Hi Riku,

I am in touch with the OpenSSL maintainer who authored most of the assembler code in OpenSSL (for all architectures).

ARMv8 versions will likely be done in collaboration with him, including (NEON) accelerated versions of SHA and AES (as the crypto extensions on v8 are optional). I will keep you informed about when any of this is expected to appear upstream.
