This patch adds a new primitive crypto_grab_spawn which is meant to replace crypto_init_spawn and crypto_init_spawn2. Under the new scheme the user no longer has to worry about reference counting the alg object before it is subsumed by the spawn. It is pretty much an exact copy of crypto_grab_aead. Prior to calling this function spawn->frontend and spawn->inst must have been set. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

This trims off a couple of instructions of the total size of the core AES transform by reordering the final branch in the AES-192 code path with the rounds that are performed regardless of whether the branch is taken or not. Other than the slight size reduction, this has no performance benefit. Fix up a comment regarding the prototype of this function while we're at it.

This replaces the SHA-512 NEON module with the faster and more versatile implementation from the OpenSSL project. It consists of both a NEON and a generic ASM version of the core SHA-512 transform, where the NEON version reverts to the ASM version when invoked in non-process context. This patch is based on the OpenSSL upstream version b1a5d1c65208 of sha512-armv4.pl, which can be found here: https://git.openssl.org/gitweb/?p=openssl.git;h=b1a5d1c65208 Performance relative to the generic implementation (measured using tcrypt.ko mode=306 sec=1 running on a Cortex-A57 under KVM): input size block size asm neon old neon 16 16 1.39 2.54 2.21 64 16 1.32 2.33 2.09 64 64 1.38 2.53 2.19 256 16 1.31 2.28 2.06 256 64 1.38 2.54 2.25 256 256 1.40 2.77 2.39 1024 16 1.29 2.22 2.01 1024 256 1.40 2.82 2.45 1024 1024 1.41 2.93 2.53 2048 16 1.33 2.21 2.00 2048 256 1.40 2.84 2.46 2048 1024 1.41 2.96 2.55 2048 2048 1.41 2.98 2.56 4096 16 1.34 2.20 1.99 4096 256 1.40 2.84 2.46 4096 1024 1.41 2.97 2.56 4096 4096 1.41 3.01 2.58 8192 16 1.34 2.19 1.99 8192 256 1.40 2.85 2.47 8192 1024 1.41 2.98 2.56 8192 4096 1.41 2.71 2.59 8192 8192 1.51 3.51 2.69 Acked-by: Jussi Kivilinna <jussi.kivilinna@iki.fi> Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

Add crypto compression alg for 842 hardware compression and decompression, using the alg name "842" and driver_name "842-nx". This uses only the PowerPC coprocessor hardware for 842 compression. It also uses the hardware for decompression, but if the hardware fails it will fall back to the 842 software decompression library, so that decompression never fails (for valid 842 compressed buffers). A header must be used in most cases, due to the hardware's restrictions on the buffers being specifically aligned and sized. Due to the header this driver adds, compressed buffers it creates cannot be directly passed to the 842 software library for decompression. However, compressed buffers created by the software 842 library can be passed to this driver for hardware 842 decompression (with the exception of buffers containing the "short data" template, as lib/842/842.h explains).

Simplify the pSeries NX-842 driver: do not expect incoming buffers to be exactly page-sized; do not break up input buffers to compress smaller blocks; do not use any internal headers in the compressed data blocks; remove the software decompression implementation; implement the pSeries nx842_constraints. This changes the pSeries NX-842 driver to perform constraints-based compression so that it only needs to compress one entire input block at a time. This removes the need for it to split input data blocks into multiple compressed data sections in the output buffer, and removes the need for any extra header info in the compressed data; all that is moved (in a later patch) into the main crypto 842 driver. Additionally, the 842 software decompression implementation is no longer needed here, as the crypto 842 driver will use the generic software 842 decompression function as a fallback if any hardware 842 driver fails.

Add "constraints" for the NX-842 driver. The constraints are used to indicate what the current NX-842 platform driver is capable of. The constraints tell the NX-842 user what alignment, min and max length, and length multiple each provided buffers should conform to. These are required because the 842 hardware requires buffers to meet specific constraints that vary based on platform - for example, the pSeries max length is much lower than the PowerNV max length.

Add NX-842 frontend that allows using either the pSeries platform or PowerNV platform driver (to be added by later patch) for the NX-842 hardware.

Move the entire NX-842 driver for the pSeries platform from the file nx-842.c to nx-842-pseries.c. This is required by later patches that add NX-842 support for the PowerNV platform. This patch does not alter the content of the pSeries NX-842 driver at all, it only changes the filename.

Change the crypto 842 compression alg to use the software 842 compression and decompression library. Add the crypto driver_name as "842-generic". Remove the fallback to LZO compression. Previously, this crypto compression alg attemped 842 compression using PowerPC hardware, and fell back to LZO compression and decompression if the 842 PowerPC hardware was unavailable or failed. This should not fall back to any other compression method, however; users of this crypto compression alg can fallback if desired, and transparent fallback tricks callers into thinking they are getting 842 compression when they actually get LZO compression - the failure of the 842 hardware should not be transparent to the caller. The crypto compression alg for a hardware device also should not be located in crypto/ so this is now a software-only implementation that uses the 842 software compression/decompression library.

Add 842-format software compression and decompression functions. Update the MAINTAINERS 842 section to include the new files. The 842 compression function can compress any input data into the 842 compression format. The 842 decompression function can decompress any standard-format 842 compressed data - specifically, either a compressed data buffer created by the 842 software compression function, or a compressed data buffer created by the 842 hardware compressor (located in PowerPC coprocessors). The 842 compressed data format is explained in the header comments. This is used in a later patch to provide a full software 842 compression and decompression crypto interface.
