      crypto: ux500 - make interrupt mode plausible · e1f8859e
      由 Arnd Bergmann 提交于 
      The interrupt handler in the ux500 crypto driver has an obviously
incorrect way to access the data buffer, which for a while has
caused this build warning:

../ux500/cryp/cryp_core.c: In function 'cryp_interrupt_handler':
../ux500/cryp/cryp_core.c:234:5: warning: passing argument 1 of '__fswab32' makes integer from pointer without a cast [enabled by default]

There are at least two, possibly three problems here:
a) when writing into the FIFO, we copy the pointer rather than the
   actual data we want to give to the hardware
b) the data pointer is an array of 8-bit values, while the FIFO
   is 32-bit wide, so both the read and write access fail to do
   a proper type conversion
c) This seems incorrect for big-endian kernels, on which we need to
   byte-swap any register access, but not normally FIFO accesses,
   at least the DMA case doesn't do it either.

This converts the bogus loop to use the same readsl/writesl pair
that we use for the two other modes (DMA and polling). This is
more efficient and consistent, and probably correct for endianess.

The bug has existed since the driver was first merged, and was
probably never detected because nobody tried to use interrupt mode.
It might make sense to backport this fix to stable kernels, depending
on how the crypto maintainers feel about that.

      crypto: qce - Qualcomm crypto engine driver · ec8f5d8f
      由 Stanimir Varbanov 提交于 
      The driver is separated by functional parts. The core part
implements a platform driver probe and remove callbaks.
The probe enables clocks, checks crypto version, initialize
and request dma channels, create done tasklet and init
crypto queue and finally register the algorithms into crypto
core subsystem.

- DMA and SG helper functions
 implement dmaengine and sg-list helper functions used by
 other parts of the crypto driver.

- ablkcipher algorithms
 implementation of AES, DES and 3DES crypto API callbacks,
 the crypto register alg function, the async request handler
 and its dma done callback function.

- SHA and HMAC transforms
 implementation and registration of ahash crypto type.
 It includes sha1, sha256, hmac(sha1) and hmac(sha256).

- infrastructure to setup the crypto hw
 contains functions used to setup/prepare hardware registers for
 all algorithms supported by the crypto block. It also exports
 few helper functions needed by algorithms:
	- to check hardware status
	- to start crypto hardware
	- to translate data stream to big endian form

 Adds register addresses and bit/masks used by the driver
 as well.

      crypto: fips - only panic on bad/missing crypto mod signatures · 002c77a4
      由 Jarod Wilson 提交于 
      Per further discussion with NIST, the requirements for FIPS state that
we only need to panic the system on failed kernel module signature checks
for crypto subsystem modules. This moves the fips-mode-only module
signature check out of the generic module loading code, into the crypto
subsystem, at points where we can catch both algorithm module loads and
mode module loads. At the same time, make CONFIG_CRYPTO_FIPS dependent on
CONFIG_MODULE_SIG, as this is entirely necessary for FIPS mode.

v2: remove extraneous blank line, perform checks in static inline
function, drop no longer necessary fips.h include.

      crypto: aes - AES CTR x86_64 "by8" AVX optimization · 22cddcc7
      由 chandramouli narayanan 提交于 
      This patch introduces "by8" AES CTR mode AVX optimization inspired by
Intel Optimized IPSEC Cryptograhpic library. For additional information,
please see:
http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=22972

The functions aes_ctr_enc_128_avx_by8(), aes_ctr_enc_192_avx_by8() and
aes_ctr_enc_256_avx_by8() are adapted from
Intel Optimized IPSEC Cryptographic library. When both AES and AVX features
are enabled in a platform, the glue code in AESNI module overrieds the
existing "by4" CTR mode en/decryption with the "by8"
AES CTR mode en/decryption.

On a Haswell desktop, with turbo disabled and all cpus running
at maximum frequency, the "by8" CTR mode optimization
shows better performance results across data & key sizes
as measured by tcrypt.

The average performance improvement of the "by8" version over the "by4"
version is as follows:

For 128 bit key and data sizes >= 256 bytes, there is a 10-16% improvement.
For 192 bit key and data sizes >= 256 bytes, there is a 20-22% improvement.
For 256 bit key and data sizes >= 256 bytes, there is a 20-25% improvement.

A typical run of tcrypt with AES CTR mode encryption of the "by4" and "by8"
optimization shows the following results:

crypto: Incorporate feed back to AES CTR mode optimization patch

Specifically, the following:
a) alignment around main loop in aes_ctrby8_avx_x86_64.S
b) .rodata around data constants used in the assembely code.
c) the use of CONFIG_AVX in the glue code.
d) fix up white space.
e) informational message for "by8" AES CTR mode optimization
f) "by8" AES CTR mode optimization can be simply enabled
if the platform supports both AES and AVX features. The
optimization works superbly on Sandybridge as well.

Testing on Haswell shows no performance change since the last.

Testing on Sandybridge shows that the "by8" AES CTR mode optimization
greatly improves performance.

      crypto: crc32c-pclmul - Shrink K_table to 32-bit words · 473946e6
      由 George Spelvin 提交于 
      There's no need for the K_table to be made of 64-bit words.  For some
reason, the original authors didn't fully reduce the values modulo the
CRC32C polynomial, and so had some 33-bit values in there.  They can
all be reduced to 32 bits.

Doing that cuts the table size in half.  Since the code depends on both
pclmulq and crc32, SSE 4.1 is obviously present, so we can use pmovzxdq
to fetch it in the correct format.

This adds (measured on Ivy Bridge) 1 cycle per main loop iteration
(CRC of up to 3K bytes), less than 0.2%.  The hope is that the reduced
D-cache footprint will make up the loss in other code.

Two other related fixes:
* K_table is read-only, so belongs in .rodata, and
* There's no need for more than 8-byte alignment

      Update to makefiles etc.
Don't update the firmware/Makefile yet since there is no FW binary in
the crypto repo yet. This will be added later.
