crypto: doc - improve the skcipher API example code
Rewrite the skcipher API example, changing it to encrypt a buffer with
AES-256-XTS. This addresses various problems with the previous example:
- It requests a specific driver "cbc-aes-aesni", which is unusual.
Normally users ask for "cbc(aes)", not a specific driver.
- It encrypts only a single AES block. For the reader, that doesn't
clearly distinguish the "skcipher" API from the "cipher" API.
- Showing how to encrypt something with bare CBC is arguably a poor
choice of example, as it doesn't follow modern crypto trends. Now,
usually authenticated encryption is recommended, in which case the
user would use the AEAD API, not skcipher. Disk encryption is still a
legitimate use for skcipher, but for that usually XTS is recommended.
- Many other bugs and poor coding practices, such as not setting
CRYPTO_TFM_REQ_MAY_SLEEP, unnecessarily allocating a heap buffer for
the IV, unnecessary NULL checks, using a pointless wrapper struct, and

crypto: caam - limit output IV to CBC to work around CTR mode DMA issue
The CAAM driver currently violates an undocumented and slightly
controversial requirement imposed by the crypto stack that a buffer
referred to by the request structure via its virtual address may not
be modified while any scatterlists passed via the same request
structure are mapped for inbound DMA.
This may result in errors like
alg: aead: decryption failed on test 1 for gcm_base(ctr-aes-caam,ghash-generic): ret=74
alg: aead: Failed to load transform for gcm(aes): -2
on non-cache coherent systems, due to the fact that the GCM driver
passes an IV buffer by virtual address which shares a cacheline with
the auth_tag buffer passed via a scatterlist, resulting in corruption
of the auth_tag when the IV is updated while the DMA mapping is live.
Since the IV that is returned to the caller is only valid for CBC mode,
and given that the in-kernel users of CBC (such as CTS) don't trigger the
same issue as the GCM driver, let's just disable the output IV generation
for all modes except CBC for the time being.

crypto: jitter - update implementation to 2.1.2
The Jitter RNG implementation is updated to comply with upstream version
2.1.2. The change covers the following aspects:
* Time variation measurement is conducted over the LFSR operation
instead of the XOR folding
* Invcation of stuck test during initialization
* Removal of the stirring functionality and the Von-Neumann
unbiaser as the LFSR using a primitive and irreducible polynomial
generates an identical distribution of random bits
This implementation was successfully used in FIPS 140-2 validations
as well as in German BSI evaluations.
This kernel implementation was tested as follows:
* The unchanged kernel code file jitterentropy.c is compiled as part
of user space application to generate raw unconditioned noise
data. That data is processed with the NIST SP800-90B non-IID test
tool to verify that the kernel code exhibits an equal amount of noise
as the upstream Jitter RNG version 2.1.2.
* Using AF_ALG with the libkcapi tool of kcapi-rng the Jitter RNG was
output tested with dieharder to verify that the output does not
exhibit statistical weaknesses. The following command was used:
kcapi-rng -n "jitterentropy_rng" -b
100000000000 | dieharder -a -g 200
* The unchanged kernel code file jitterentropy.c is compiled as part
of user space application to test the LFSR implementation. The
LFSR is injected a monotonically increasing counter as input and
the output is fed into dieharder to verify that the LFSR operation
does not exhibit statistical weaknesses.
* The patch was tested on the Muen separation kernel which returns
a more coarse time stamp to verify that the Jitter RNG does not cause
regressions with its initialization test considering that the Jitter
RNG depends on a high-resolution timer.

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).

to the requests, and by using this number instead of the 'last' bit
found on the descriptors to process them.

When enabling IOMMU support, the following issue becomes visible

Even though the output sequence length is set to zero, the crypto engine

in SEQ OUT PTR command - which is either generated in SW in case of
caam/jr or in HW in case of caam/qi, caam/qi2).
The DMA read operation will trigger an IOMMU fault since the address in
the SEQ OUT PTR is "dummy" (set to zero / not obtained via DMA API
mapping).
1. In case of caam/jr, avoid the IOMMU fault by clearing the SGF bit
in SEQ OUT PTR command.
2. In case of caam/qi - setting address, bpid, length to zero for output
entry in the compound frame has a special meaning (cf. CAAM RM):
"Output frame = Unspecified, Input address = Y. A unspecified frame is
indicated by an unused SGT entry (an entry in which the Address, Length,
and BPID fields are all zero). SEC obtains output buffers from BMan as
prescribed by the preheader."
Since no output buffers are needed, modify the preheader by setting
(ABS = 1, ADDBUF = 0):
-"ABS = 1 means obtain the number of buffers in ADDBUF (0 or 1) from
the pool POOL ID"
-ADDBUF: "If ABS is set, ADD BUF specifies whether to allocate
a buffer or not"
3. In case of caam/qi2, since engine:
-does not support FLE[FMT]=2'b11 ("unused" entry) mentioned in DPAA2 RM
-requires output entry to be present, even if not used
the solution chosen is to leave output frame list entry zeroized.
