crypto: x86/sha512_ssse3 - fixup for asm function prototype change

2015-04-24T12:09:01+00:00

Patch e68410ebf626 ("crypto: x86/sha512_ssse3 - move SHA-384/512
SSSE3 implementation to base layer") changed the prototypes of the
core asm SHA-512 implementations so that they are compatible with
the prototype used by the base layer.

However, in one instance, the register that was used for passing the
input buffer was reused as a scratch register later on in the code,
and since the input buffer param changed places with the digest param
-which needs to be written back before the function returns- this
resulted in the scratch register to be dereferenced in a memory write
operation, causing a GPF.

Fix this by changing the scratch register to use the same register as
the input buffer param again.

Pull crypto update from Herbert Xu:
 "Here is the crypto update for 4.1:

  New interfaces:
   - user-space interface for AEAD
   - user-space interface for RNG (i.e., pseudo RNG)

  New hashes:
   - ARMv8 SHA1/256
   - ARMv8 AES
   - ARMv8 GHASH
   - ARM assembler and NEON SHA256
   - MIPS OCTEON SHA1/256/512
   - MIPS img-hash SHA1/256 and MD5
   - Power 8 VMX AES/CBC/CTR/GHASH
   - PPC assembler AES, SHA1/256 and MD5
   - Broadcom IPROC RNG driver

  Cleanups/fixes:
   - prevent internal helper algos from being exposed to user-space
   - merge common code from assembly/C SHA implementations
   - misc fixes"

crypto: x86/sha512_ssse3 - move SHA-384/512 SSSE3 implementation to base layer

2015-04-10T13:39:48+00:00

This removes all the boilerplate from the existing implementation,
and replaces it with calls into the base layer.  It also changes the
prototypes of the core asm functions to be compatible with the base
prototype

  void (sha512_block_fn)(struct sha256_state *sst, u8 const *src, int blocks)

so that they can be passed to the base layer directly.

x86/asm: Replace "MOVQ $imm, %reg" with MOVL

2015-04-01T11:17:39+00:00

There is no reason to use MOVQ to load a non-negative immediate
constant value into a 64-bit register. MOVL does the same, since
the upper 32 bits are zero-extended by the CPU.

This makes the code a bit smaller, while leaving functionality
unchanged.
