d96cf190e5 crypto: inside-secure - Fixed corner case TRC admin RAM probing issue
This patch fixed a corner case admin RAM probing issue witnessed on the
Xilinx VCU118 FPGA development board with an EIP197 configuration with
4096 words of admin RAM, of which only 2050 were recognised.

b8c5d882c8 crypto: inside-secure - Fix stability issue with Macchiatobin
This patch corrects an error in the Transform Record Cache initialization
code that was causing intermittent stability problems on the Macchiatobin
board.

Unfortunately, due to HW platform specifics, the problem could not happen
on the main development platform, being the VCU118 Xilinx development
board. And since it was a problem with hash table access, it was very
dependent on the actual physical context record DMA buffers being used,
i.e. with some (bad) luck it could seemingly work quit stable for a while.

8d9d4bdc49 hwrng: omap3-rom - Use runtime PM instead of custom functions
Nowadays we have runtime PM, and we can use it with autosuspend_timeout
to idle things automatically. This allows us to get rid of the custom
PM implementation.

We enable clocks and init RNG in runtime_resume, and reset RNG and
disable clocks in runtime_suspend. And then omap3_rom_rng_read()
becomes very simple and we don't need the old functions for
omap3_rom_rng_idle() and omap3_rom_rng_get_random(). We can now also
get rid of pr_fmt as we're using dev_err instead.

Let's update omap3-rom-rng to use standard driver data to make it easier
to add runtime PM support in the following patch. Just use it for the
rng ops and clock for now. Let's still keep also old rng_clk still around,
we will remove delayed work and rng_clk with runtime PM in the next patch.

Similar to commit 62f95ae805 ("hwrng: omap - Set default quality")
we need to initialize the default quality for the RNG to be used.

produce much data at all.

When unloading omap3-rom-rng, we'll get the following:

0c0ef9ea6f hwrng: omap3-rom - Fix missing clock by probing with device tree
Commit 0ed266d7ae ("clk: ti: omap3: cleanup unnecessary clock aliases")
removed old omap3 clock framework aliases but caused omap3-rom-rng to
stop working with clock not found error.

Based on discussions on the mailing list it was requested by Tero Kristo
that it would be best to fix this issue by probing omap3-rom-rng using
device tree to provide a proper clk property. The other option would be
to add back the missing clock alias, but that does not help moving things
forward with removing old legacy platform_data.

Let's also add a proper device tree binding and keep it together with
the fix.

1769f704e5 crypto: inside-secure - Add SM4 based authenc AEAD ciphersuites
This patch adds support for the authenc(hmac(sha1),cbc(sm4)),
authenc(hmac(sm3),cbc(sm4)), authenc(hmac(sha1),rfc3686(ctr(sm4))),
and authenc(hmac(sm3),rfc3686(ctr(sm4))) aead ciphersuites.
These are necessary to support IPsec according to the Chinese standard
GM/T 022-1014 - IPsec VPN specification.

Note that there are no testvectors present in testmgr for these
ciphersuites. However, considering all building blocks have already been
verified elsewhere, it is fair to assume the generic implementation to be
correct-by-construction.
The hardware implementation has been fuzzed against this generic
implementation by means of a locally modified testmgr. The intention is
to upstream these testmgr changes but this is pending other testmgr changes
being made by Eric Biggers.

The patch has been tested with the eip197c_iewxkbc configuration on the
Xilinx VCU118 development board, using the abovementioned modified testmgr

This patch applies on top of "Add support for SM4 ciphers" and needs to
be applied before "Add (HMAC) SHA3 support".

2eb2d198bd crypto: aegis128-neon - use Clang compatible cflags for ARM
The next version of Clang will start policing compiler command line
options, and will reject combinations of -march and -mfpu that it
thinks are incompatible.

This results in errors like

  clang-10: warning: ignoring extension 'crypto' because the 'armv7-a'
  architecture does not support it [-Winvalid-command-line-argument]
  /tmp/aegis128-neon-inner-5ee428.s: Assembler messages:
            /tmp/aegis128-neon-inner-5ee428.s:73: Error: selected
  processor does not support `aese.8 q2,q14' in ARM mode

when buiding the SIMD aegis128 code for 32-bit ARM, given that the
'armv7-a' -march argument is considered to be compatible with the
ARM crypto extensions. Instead, we should use armv8-a, which does
allow the crypto extensions to be enabled.

a60619211d crypto: inside-secure - Add support for the Chacha20-Poly1305 AEAD
This patch adds support for the Chacha20-Poly1305 cipher suite.
It adds both the basic rfc7539(chacha20,poly1305) as well as the
rfc7539esp(chacha20,poly1305) variant for IPsec ESP acceleration.

changes since v1:
- rebased on top of DES library changes done on cryptodev/master
- fixed crypto/Kconfig so that generic fallback is compiled as well

changes since v2:
- nothing

changes since v3:
- Fixed a problem where the tcrypt performance test would run fully on the
  fallback cipher instead of the HW due to using an AAD length of 8 for
  rfc7539esp. While this is not actually legal ESP (which includes SPI and
  sequence number in the AAD as well), it is both inconvenient and not
  necessary to run these vectors on the fallback cipher.
- Due to above, also realised that for plain (non-ESP) rfc7539, you
  probably want to be able to run vectors with less than 8 bytes of AAD
  on the HW, and this is actually possible as long as cryptlen is large
  enough, so made that possible as well.

11031c0d7d crypto: arm64/gcm-ce - implement 4 way interleave
To improve performance on cores with deep pipelines such as ThunderX2,
reimplement gcm(aes) using a 4-way interleave rather than the 2-way
interleave we use currently.

This comes down to a complete rewrite of the GCM part of the combined
GCM/GHASH driver, and instead of interleaving two invocations of AES
with the GHASH handling at the instruction level, the new version
uses a more coarse grained approach where each chunk of 64 bytes is
encrypted first and then ghashed (or ghashed and then decrypted in
the converse case).

The core NEON routine is now able to consume inputs of any size,
and tail blocks of less than 64 bytes are handled using overlapping
loads and stores, and processed by the same 4-way encryption and
hashing routines. This gets rid of most of the branches, and avoids
having to return to the C code to handle the tail block using a
stack buffer.

The table below compares the performance of the old driver and the new
one on various micro-architectures and running in various modes.

        |     AES-128      |     AES-192      |     AES-256      |

ec05a74f9b crypto: testmgr - add another gcm(aes) testcase
Add an additional gcm(aes) test case that triggers the code path in
the new arm64 driver that deals with tail blocks whose size is not
a multiple of the block size, and where the size of the preceding
input is a multiple of 64 bytes.

7a6eda5b8d crypto: talitos - fix hash result for VMAP_STACK
When VMAP_STACK is selected, stack cannot be DMA-mapped.
Therefore, the hash result has to be DMA-mapped in the request

5b0fe95523 crypto: algif_skcipher - Use chunksize instead of blocksize
When algif_skcipher does a partial operation it always process data
that is a multiple of blocksize.  However, for algorithms such as
CTR this is wrong because even though it can process any number of
bytes overall, the partial block must come at the very end and not
in the middle.

This is exactly what chunksize is meant to describe so this patch
changes blocksize to chunksize.
