b8151220f3 crypto: inside-secure - Fixed authenc w/ (3)DES fails on Macchiatobin
Fixed 2 copy-paste mistakes in the commit mentioned below that caused
authenc w/ (3)DES to consistently fail on Macchiatobin (but strangely
work fine on x86+FPGA??).
Now fully tested on both platforms.

Fixes: 13a1bb93f7 ("crypto: inside-secure - Fixed warnings...")

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".

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.

5bdb6e6aa5 crypto: inside-secure - fix incorrect skcipher output IV
This patch fixes corruption issues with the skcipher output IV
witnessed on x86+EIP197-FPGA (devboard). The original fix, commit
57660b11d5 ("crypto: inside-secure - implement IV retrieval"),
attempted to write out the result IV through the context record.
However, this is not a reliable mechanism as there is no way of
knowing the hardware context update actually arrived in memory, so
it is possible to read the old contents instead of the updated IV.
(and indeed, this failed for the x86/FPGA case)

The alternative approach used here recognises the fact that the
result IV for CBC is actually the last cipher block, which is the last
input block in case of decryption and the last output block in case
of encryption. So the result IV is taken from the input data buffer
respectively the output data buffer instead, which *is* reliable.

8933259042 crypto: inside-secure - do not rely on the hardware last bit for result descriptors
When performing a transformation the hardware is given result
descriptors to save the result data. Those result descriptors are
batched using a 'first' and a 'last' bit. There are cases were more
descriptors than needed are given to the engine, leading to the engine
only using some of them, and not setting the last bit on the last
descriptor we gave. This causes issues were the driver and the hardware
aren't in sync anymore about the number of result descriptors given (as
the driver do not give a pool of descriptor to use for any
transformation, but a pool of descriptors to use *per* transformation).

This patch fixes it by attaching the number of given result descriptors
to the requests, and by using this number instead of the 'last' bit
found on the descriptors to process them.

231baecdef crypto: clarify name of WEAK_KEY request flag
CRYPTO_TFM_REQ_WEAK_KEY confuses newcomers to the crypto API because it
sounds like it is requesting a weak key.  Actually, it is requesting
that weak keys be forbidden (for algorithms that have the notion of
"weak keys"; currently only DES and XTS do).

Also it is only one letter away from CRYPTO_TFM_RES_WEAK_KEY, with which
it can be easily confused.  (This in fact happened in the UX500 driver,
though just in some debugging messages.)

Therefore, make the intent clear by renaming it to
CRYPTO_TFM_REQ_FORBID_WEAK_KEYS.

2b78aeb366 crypto: inside-secure - remove useless setting of type flags
Remove the unnecessary setting of CRYPTO_ALG_TYPE_SKCIPHER.
Commit 2c95e6d978 ("crypto: skcipher - remove useless setting of type
flags") took care of this everywhere else, but a few more instances made
it into the tree at about the same time.  Squash them before they get
copy+pasted around again.

This patch shouldn't change any actual behavior.

e5c8ee1f7c crypto: inside-secure - initialize first_rdesc to make GCC happy
In the cipher safexcel_send_req function, GCC warns that
first_rdesc may be used uninitialized. While this should never
happen, this patch removes the warning by initializing this
variable to NULL to make GCC happy.

This was reported by the kbuild test robot.

2c95e6d978 crypto: skcipher - remove useless setting of type flags
Some skcipher algorithms set .cra_flags = CRYPTO_ALG_TYPE_SKCIPHER.  But
this is redundant with the C structure type ('struct skcipher_alg'), and
crypto_register_skcipher() already sets the type flag automatically,
clearing any type flag that was already there.  Apparently the useless
assignment has just been copy+pasted around.

So, remove the useless assignment from all the skcipher algorithms.

This patch shouldn't change any actual behavior.
